In the fast-paced world of ecommerce, success isn't just about driving traffic. It's about having the right product, in the right place, at the right time. For sellers on competitive platforms like Amazon, Walmart, and eBay, poor inventory control leads to stockouts, lost sales, and plummeting search rankings. Conversely, excess stock ties up capital, increases holding costs, and risks obsolescence. Mastering your inventory is no longer optional; it's the core engine of profitability and scale.

This guide presents ten proven inventory management best practices, tailored specifically for ambitious ecommerce brands. We'll move beyond generic advice to provide actionable strategies, real-world examples, and implementation checklists designed to turn inventory from a liability into a strategic asset. You will learn how to:

• Prioritize your most valuable products with ABC analysis.
• Prevent stockouts with precise safety stock and reorder point calculations.
• Reduce waste and carrying costs using FIFO and JIT methodologies.
• Optimize your SKU portfolio to maximize profit and simplify operations.

Implementing a robust strategy often involves complex logistics. To truly unlock growth and gain a significant competitive edge, modern businesses should consider how Third Party Logistics (3PL) business storage is increasingly seen as a best practice for the 21st century. By leveraging specialized partners, you can focus on core business functions while ensuring your inventory is handled efficiently. This comprehensive approach, combining smart internal practices with strategic external support, is key to building a resilient and profitable online business. Let's dive into the practices that will help you achieve just that.

1. Implement Real-Time Inventory Tracking Systems

For modern ecommerce brands, manual inventory counting in spreadsheets is a recipe for disaster. Real-time inventory tracking systems provide immediate, automated visibility into your stock levels across every sales channel, from marketplaces like Amazon and Walmart to your D2C Shopify store. These platforms automatically sync and update inventory counts the instant a sale is made, an order is fulfilled, or a return is processed.

This continuous synchronization is one of the most crucial inventory management best practices because it prevents overselling, a costly mistake that leads to canceled orders, poor customer reviews, and severe marketplace penalties. Platforms like Amazon can suppress your listings or even suspend your account for maintaining inaccurate inventory data, directly impacting your visibility and revenue. By integrating your sales channels, warehouse management system (WMS), and fulfillment services, you create a single source of truth for your stock.

How to Implement Real-Time Tracking

Successfully implementing a real-time system requires more than just choosing software like Cin7, NetSuite, or a Shopify app like Stocky. It demands a strategic approach to maintain data accuracy and operational efficiency. For instance, Amazon sellers often leverage tools like Algopix to gain precise inventory insights that directly improve Amazon sales by preventing stockouts on high-performing ASINs.

Key Insight: Real-time tracking isn't just about preventing stockouts; it's about protecting your brand's reputation and search ranking on competitive marketplaces. Inaccurate data is a direct path to penalties and lost customer trust.

Actionable Tips for Implementation

• Prioritize High-Velocity SKUs: Start your integration with your top-selling products. This minimizes initial complexity and delivers the most immediate impact.
• Establish Automated Alerts: Configure your system to send notifications at specific stock thresholds (e.g., 30%, 15%, and 5%) to give your purchasing team ample time to reorder.
• Set Dynamic Sync Frequency: Sync inventory every 2-4 hours for high-demand products, especially during peak seasons like Black Friday, to prevent overselling when order velocity is highest.
• Conduct Spot Audits: Use your system's data to perform daily or weekly cycle counts on a small subset of SKUs. This helps catch any discrepancies from theft, damage, or receiving errors before they escalate.

2. Adopt the ABC Analysis (Pareto Principle) for Inventory Prioritization

Not all products in your catalog are created equal. ABC analysis, rooted in the Pareto Principle (the 80/20 rule), is an inventory categorization technique that groups SKUs into three tiers based on their value to the business. This framework allows you to prioritize your focus, capital, and resources on the products that matter most, rather than treating every item with the same level of attention.

This strategic classification is one of the most effective inventory management best practices because it directs your efforts where they will generate the highest return. Typically, "A-items" are the top ~20% of your products that generate ~80% of your revenue. "B-items" are the next ~30% contributing ~15% of revenue, and "C-items" are the remaining ~50% of products that only account for ~5% of revenue. For marketplace sellers, focusing ad spend and optimization efforts on A-items can dramatically boost profitability and search ranking.

How to Implement ABC Analysis

Implementing ABC analysis starts with data. You calculate the annual consumption value for each SKU (Annual Demand x Item Cost) and rank them from highest to lowest. For example, Amazon sellers can use this data to allocate their A+ Content budget exclusively to their A-tier products, maximizing conversion rates on their most valuable ASINs. This prevents wasting resources on optimizing low-impact, C-tier product listings that contribute minimally to the bottom line.

Key Insight: ABC analysis transforms inventory management from a uniform task into a strategic, value-based system. It ensures your most profitable products receive the tightest control, best forecasting, and highest service levels.

Actionable Tips for Implementation

• Use Margin, Not Just Revenue: Calculate your tiers using profit margin instead of revenue to identify your true "A-items." A high-revenue, low-margin product may actually be a B- or C-item when viewed through a profitability lens.
• Review Classifications Quarterly: Product lifecycles and consumer demand change. Re-evaluate your ABC categories every quarter to ensure your inventory strategy aligns with current sales performance and market trends.
• Tailor Management Strategies: Apply different rules for each category. Use sophisticated forecasting and maintain higher safety stock for A-items, automated reordering for B-items, and consider a "run-to-stockout" approach for non-critical C-items.
• Align Budgets to Tiers: Allocate your advertising and marketing budgets according to ABC classifications. A common model is dedicating 70% of spend to A-items, 20% to B-items, and just 10% to C-items.

3. Establish Safety Stock Levels and Demand Forecasting

Relying on guesswork to manage stock is a direct path to lost revenue. Safety stock is the extra inventory you hold to guard against unpredictable demand spikes and supply chain delays, while demand forecasting uses historical data to predict future sales. This combination is one of the most powerful inventory management best practices because it prevents the two most expensive inventory mistakes: stockouts, which kill sales velocity and marketplace rankings, and overstocking, which ties up capital in slow-moving goods.

For marketplace sellers, forecasting is non-negotiable. An Amazon FBA stockout not only means lost sales but also a drop in your Best Seller Rank (BSR), making it harder to regain momentum. Similarly, Walmart sellers must adjust safety stock levels for major retail events like back-to-school and holiday seasons to avoid penalties for unfulfilled orders.

How to Implement Forecasting and Safety Stock

Effective implementation requires a data-driven approach, not intuition. It involves analyzing past sales, understanding market trends, and setting precise reorder triggers. For example, fashion brands often use forecasting to build inventory 3-4 months ahead of seasonal peaks, while Amazon sellers can use historical Amazon sales data from tools like Keepa to anticipate demand shifts during Q4. The goal is to create a dynamic model that adapts to changing consumer behavior and supply chain performance.

Key Insight: Safety stock isn't "just-in-case" inventory; it's a strategic buffer calculated to protect your revenue and search rankings against specific, quantifiable risks like supplier delays and unexpected demand.

Actionable Tips for Implementation

• Analyze Historical Data: Use at least two years of sales data to identify clear seasonal patterns and growth trends for accurate forecasting.
• Segment by Channel: Create separate forecasts for each sales channel (e.g., Amazon, Walmart, Shopify) as customer behavior and demand drivers often differ significantly.
• Calculate Safety Stock Precisely: Use a standard formula, such as (Max Daily Sales × Max Lead Time) – (Average Daily Sales × Average Lead Time), to set a data-backed buffer.
• Monitor Supplier Lead Times: Regularly check your suppliers' fulfillment speed and adjust your reorder points and safety stock levels accordingly to avoid unexpected stockouts.

4. Optimize Inventory Turnover and Reduce Holding Costs

Inventory turnover is a critical financial metric that reveals how many times your inventory is sold and replaced within a specific period. Calculated as Cost of Goods Sold (COGS) divided by the average inventory value, a higher turnover rate indicates efficient sales and lean inventory management. For ecommerce brands, fast turnover directly improves cash flow, reduces the risk of stock obsolescence, and frees up capital that can be reinvested into growth initiatives like marketing or new product development.

This is one of the most impactful inventory management best practices because slow-moving inventory quietly drains your profits. Holding costs, which include warehousing fees, insurance, handling, and potential spoilage or damage, can easily consume 25-35% of your inventory's value annually. For marketplace sellers, high turnover also sends positive signals to algorithms on platforms like Amazon, correlating with fresh stock and improved search rankings.

How to Improve Turnover and Cut Costs

Improving inventory turnover isn't just about selling more; it's about selling smarter. It requires a proactive strategy to identify and liquidate slow-moving products before their holding costs spiral out of control. For example, Amazon FBA sellers in competitive niches often aim for an annual turnover of 4-6x to stay profitable after fees, while fast-fashion D2C brands might target 8-12x turnover through aggressive promotional cycles.

Key Insight: Inventory sitting on a shelf is a depreciating asset, not a stable one. Every day it remains unsold, its true cost increases due to holding fees, tying up cash that could be used for scaling your business.

Actionable Tips for Implementation

• Set Turnover Targets: Aim for an annual turnover rate of 6-8x for most standard ecommerce categories. Adjust this target higher for perishables and fast-fashion or lower for high-margin, slower-moving goods.
• Implement Dynamic Pricing: Automatically reduce prices by 10-20% on any inventory that has been sitting for over 60 days to stimulate sales and avoid long-term holding.
• Bundle Slow-Movers: Pair underperforming products with your best-sellers as a value-added bundle. This tactic can significantly increase Amazon sales velocity for the entire package.
• Run Strategic Clearance Campaigns: Schedule quarterly or biannual clearance events specifically to liquidate the bottom 10% of your SKUs by performance.

5. Implement First-In, First-Out (FIFO) Rotation and Shelf Life Management

For brands selling perishable or dated products, the First-In, First-Out (FIFO) method is non-negotiable. FIFO is a physical inventory management system where the oldest stock (First-In) is sold and shipped before newer stock (First-Out). This is critical for categories like food, supplements, beauty products, and pharmaceuticals to prevent waste from expired goods and ensure product quality.

Adopting FIFO is one of the most fundamental inventory management best practices for protecting your bottom line and brand integrity. Sending customers products near their expiration date leads to dissatisfaction, negative reviews, and costly returns. On marketplaces like Amazon, this can trigger quality alerts and even listing suspensions, as they enforce strict standards to protect buyers. Proper rotation ensures every customer receives a fresh, effective product, building trust and repeat business.

How to Implement FIFO and Shelf Life Management

Effective FIFO implementation goes beyond a simple "oldest out first" rule; it requires disciplined operational processes and often, technological support. It involves meticulous tracking from the moment inventory is received until it is shipped. For instance, a direct-to-consumer brand selling premium skincare must track batch numbers to ensure the first manufactured lots are picked first by their fulfillment center, guaranteeing customers receive products with maximum potency and shelf life.

Key Insight: FIFO is not just an accounting principle; it's an operational strategy that directly impacts customer satisfaction and regulatory compliance. Failing to manage shelf life is a direct path to financial loss and brand damage.

Actionable Tips for Implementation

• Label All Incoming Stock: Clearly mark all incoming inventory with the receiving date and/or expiration date. This provides an immediate visual cue for warehouse staff.
• Organize Warehouse for Rotation: Structure your shelving so that the oldest stock is physically placed at the front or most accessible picking location, making it the default choice.
• Set Up Expiration Date Alerts: Use your inventory management system to create automated alerts for stock that is 3-6 months from its expiration date. This gives you time to plan promotions or liquidations.
• Train Fulfillment Staff Rigorously: Ensure your warehouse team understands the importance of FIFO during onboarding and conduct quarterly refresher training sessions on proper picking procedures.

6. Use Just-In-Time (JIT) Inventory to Reduce Carrying Costs

Just-In-Time (JIT) inventory is a lean strategy where goods are ordered from suppliers only as they are needed for production or to fulfill customer orders. Instead of tying up capital in large volumes of safety stock, JIT focuses on receiving inventory "just in time," which significantly cuts down on warehousing space, insurance, and the risk of inventory obsolescence. This approach transforms your warehouse from a costly storage unit into a dynamic, high-velocity fulfillment center.

For ecommerce brands, especially established ones with predictable demand, JIT is one of the most effective inventory management best practices for boosting cash flow. By minimizing on-hand stock, you free up capital that can be reinvested into marketing, product development, or other growth initiatives. However, JIT demands exceptional supply chain coordination, as any disruption in logistics or supplier performance can lead to immediate stockouts and lost sales.

How to Implement JIT Inventory

A successful JIT model is built on a foundation of strong supplier relationships and highly accurate demand forecasting. It's not a strategy for new startups with erratic sales but is ideal for brands with at least 12-18 months of stable sales history. For example, direct-to-consumer fashion brands often use JIT by working with agile manufacturers who can quickly produce and ship small batches based on real-time sales data, preventing overproduction of unpopular styles.

Key Insight: JIT is more than a cost-saving tactic; it's an operational discipline. It forces you to perfect your demand forecasting and strengthen your supplier partnerships, making your entire supply chain more resilient and responsive.

Actionable Tips for Implementation

• Establish Supplier Redundancy: Build relationships with at least two or three reliable suppliers for your core products. This creates a safety net if one supplier experiences delays or quality issues.
• Negotiate Short Lead Times: JIT is only viable with fast turnarounds. Aim to negotiate lead times of four weeks or less with your key suppliers to maintain agility.
• Automate Your Reordering Process: Implement a system that automatically triggers purchase orders when stock levels hit a predetermined minimum threshold, ensuring orders are placed without manual delay.
• Start with A-Category Products: Pilot your JIT strategy with your top 20% of SKUs (your A-items). These high-velocity products will provide the clearest data on the model's effectiveness before a full rollout.

7. Implement Inventory Segmentation by Location and Channel

Treating all your inventory as one single pool is a common but costly mistake for multi-channel brands. Inventory segmentation is the practice of strategically allocating stock across different locations and sales channels based on their unique demand patterns, fulfillment requirements, and profitability. This approach moves beyond a one-size-fits-all model, allowing you to position products closer to customers and optimize for channel-specific needs, whether it's Amazon FBA, a third-party logistics (3PL) provider, or your own warehouse.

This strategic allocation is one of the most effective inventory management best practices because it directly reduces fulfillment times and shipping costs. For example, a brand selling on its Shopify store and Amazon can place a portion of its inventory in FBA to meet Prime delivery expectations, while keeping another portion at a 3PL to handle D2C orders with more control over branding and shipping. This segmentation prevents putting all your eggs in one basket and builds a more resilient and efficient supply chain.

How to Implement Inventory Segmentation

Effective segmentation starts with data analysis. Review historical sales data for each channel (e.g., Amazon, Walmart, D2C website) to understand their respective demand volumes and geographic concentrations. For Amazon sellers, this means deciding how much stock to send to FBA versus keeping at a 3PL for FBM or multi-channel fulfillment. Understanding the nuances of what Amazon FBA means for your operational costs and customer experience is critical to making the right allocation decisions.

Key Insight: Inventory segmentation isn't just about splitting stock; it's about aligning your inventory placement with channel-specific customer expectations for speed, cost, and service.

Actionable Tips for Implementation

• Allocate Based on Demand: Use historical sales data to assign inventory proportionally. If Amazon drives 60% of sales, allocate a corresponding amount of inventory to FBA or a nearby 3PL.
• Build Channel-Specific Buffers: Hold a 10-15% safety stock buffer at your fastest-growing channels to prevent stockouts during unexpected demand spikes.
• Establish Regional Hubs: For D2C brands, place inventory in warehouses on both the East and West coasts to reduce shipping zones, cut costs, and offer 2-day shipping nationwide.
• Conduct Quarterly Rebalancing: Review channel performance and profitability each quarter. Reallocate slow-moving inventory from an underperforming channel to one with higher velocity to improve turnover.

8. Establish Inventory Audits and Cycle Counts

Even with sophisticated software, the data in your inventory system can drift away from the physical reality in your warehouse. Inventory audits and cycle counts are the essential checks and balances that maintain data integrity. A full physical audit is a complete, wall-to-wall count of every item, while cycle counting is a continuous process of counting small, targeted subsets of SKUs on a rotating basis.

For ecommerce brands, this discipline is one of the most critical inventory management best practices for financial accuracy and operational health. Discrepancies between your system and physical stock can lead to stranded inventory on platforms like Amazon, where mismatched data prevents your products from being sold. Regular audits uncover hidden issues like theft, receiving errors, or undetected product damage, allowing you to correct process breakdowns before they escalate into major financial losses.

How to Implement Audits and Cycle Counts

Effective implementation moves beyond a simple year-end count and integrates counting into daily operations. For example, many successful D2C brands use a perpetual cycle counting method based on ABC analysis, where high-value 'A' items are counted daily or weekly, while slower-moving 'C' items are counted monthly or quarterly. This targeted approach is far less disruptive than a full shutdown for a physical inventory and provides more immediate, actionable data.

Key Insight: Cycle counting isn't just about correcting numbers; it's a diagnostic tool. Every significant variance you find points to a flaw in your receiving, picking, or security processes that needs to be fixed.

Actionable Tips for Implementation

• Schedule a Full Annual Audit: Conduct a full physical inventory count at least once per year, typically at year-end, to meet financial reporting and tax requirements.
• Implement ABC Cycle Counting: Count your high-value A-items daily or weekly, B-items bi-weekly or monthly, and C-items quarterly to focus efforts where they matter most.
• Use Mobile Scanners: Equip your team with mobile barcode scanners to verify on-hand quantities against system data in real-time, drastically reducing human error.
• Investigate All Variances: Set a threshold (e.g., 3-5%) and investigate any discrepancy that exceeds it to identify the root cause, whether it's theft, damage, or a process error.
• Document Every Adjustment: Maintain a clear audit trail by requiring reason codes (e.g., "damaged in warehouse," "receiving error") for every inventory adjustment made in your system.

9. Leverage Data Analytics and Predictive Modeling for Inventory Optimization

Relying solely on historical sales data for forecasting is no longer enough in a volatile ecommerce landscape. Advanced analytics and predictive modeling use machine learning (ML) and statistical algorithms to analyze vast datasets, identify hidden patterns, and predict future demand with greater accuracy. This approach moves beyond simple averages to incorporate variables like seasonality, competitor activity, marketing campaigns, and even macroeconomic trends.

Leveraging these tools is a critical component of modern inventory management best practices because it transforms inventory decisions from reactive to proactive. Instead of just reordering based on past performance, brands can anticipate shifts in consumer behavior. For example, a D2C brand might use Looker to see how a recent influencer campaign is impacting traffic and conversion rates, allowing them to adjust inventory levels for an anticipated sales lift before a stockout occurs.

How to Implement Predictive Modeling

Implementation involves more than just software; it requires a commitment to data quality and a strategic approach to model selection. Amazon sellers frequently use tools like Helium 10 to analyze historical keyword search volume and competitor sales data, forecasting seasonal demand for niche products far more accurately than basic sales reports would allow. Similarly, understanding how to apply data-driven marketing strategies can provide crucial qualitative inputs for your forecasting models.

Key Insight: Predictive analytics isn't about perfectly predicting the future. It's about reducing uncertainty and making smarter, probability-based decisions that minimize the financial risks of both overstocking and understocking.

Actionable Tips for Implementation

• Start Simple: Begin with foundational models like moving averages or exponential smoothing to establish a baseline before investing in complex AI/ML solutions.
• Prioritize Data Hygiene: Ensure your data is clean and accurate. Regularly audit sources, remove outliers, and validate information from your sales channels, WMS, and ERP systems.
• Combine Quantitative and Qualitative Data: Augment your statistical forecasts with qualitative insights, such as upcoming product launches, planned marketing promotions, or anticipated supply chain disruptions.
• Review and Refine Models: Update and test your models monthly as new sales data becomes available. Set up alerts for forecast accuracy metrics to catch model degradation early.
• Invest in Visualization: Use tools like Tableau or Power BI to translate complex data into actionable dashboards for your purchasing and operations teams. To dive deeper into the technological aspects of optimizing inventory, you can explore how hybrid BI for inventory management can be a game-changer.

10. Implement SKU Rationalization and Portfolio Optimization

SKU rationalization is the process of eliminating slow-moving, unprofitable products to simplify inventory and focus resources on top performers. For ecommerce brands, carrying excess SKUs bloats operational complexity, increases warehouse costs, and ties up capital that could be used for growth. This strategic pruning of your product portfolio is one of the most impactful inventory management best practices for boosting profitability.

Focusing your catalog allows you to concentrate marketing efforts, improve inventory turnover, and maintain fresher stock, which is especially important on marketplaces like Amazon and Walmart. By cutting the bottom 10-20% of your SKUs, you reduce the noise in your inventory system, simplify demand forecasting, and free up cash to invest in products that truly drive revenue. This approach also streamlines content management, as your team can focus on optimizing fewer product listings, ad campaigns, and A+ content pages.

How to Implement SKU Rationalization

Effective SKU rationalization requires a data-driven approach, not just intuition. Start by analyzing each SKU's contribution margin, which is the revenue left after subtracting variable costs like cost of goods sold (COGS), fulfillment fees, and direct marketing spend. For example, a D2C brand might discover that five of its 12 product color variants account for 90% of sales but 100% of its stockout headaches. Eliminating the underperforming seven variants simplifies everything from purchasing to warehouse slotting.

Key Insight: SKU rationalization isn't just about cutting products; it's a strategic reallocation of your most valuable resources: cash, warehouse space, and employee attention. A smaller, more profitable portfolio almost always outperforms a large, bloated one.

Actionable Tips for Implementation

• Analyze SKU Profitability Quarterly: Calculate the true contribution margin for every SKU, factoring in all variable costs. Rank them from most to least profitable.
• Target the Bottom 10-20%: Prioritize consolidating or discontinuing SKUs in the lowest decile for both sales volume and profit margin.
• Set Clear Criteria for New SKUs: Establish a rule that any new product must meet a specific revenue target within its first 90 days or serve a clear strategic purpose, like entering a new market.
• Manage the Discontinuation Process: Create a clear plan to liquidate discontinued inventory through discounts or bundles. Inform loyal customers and recommend suitable alternatives to prevent churn.

From Theory to Action: Building Your Inventory Management Flywheel

We've journeyed through a comprehensive set of inventory management best practices, from implementing real-time tracking systems and ABC analysis to leveraging predictive modeling and SKU rationalization. Each strategy represents a critical gear in the complex machinery of a successful ecommerce operation. However, the true power of these concepts is unlocked not by implementing them in isolation, but by integrating them into a cohesive, self-reinforcing system.

Think of it as building an "inventory flywheel." Accurate, real-time data from your tracking system (Practice #1) feeds more precise demand forecasting (Practice #3). This improved forecasting allows you to set more effective safety stock levels and reorder points, which in turn optimizes your inventory turnover (Practice #4) and reduces costly holding fees. The capital you save can then be reinvested into your high-performing "A" products, identified through ABC analysis (Practice #2), further accelerating your growth. This continuous cycle of improvement is the essence of strategic inventory control.

Key Takeaways and Your Path Forward

Mastering inventory is not a one-time setup; it is an ongoing discipline. The difference between a thriving ecommerce brand and one that struggles with cash flow often comes down to how well it manages the assets sitting in its warehouse. Poor inventory management leads to stockouts that kill sales momentum, overstocks that drain capital, and expired goods that become a total loss. Conversely, strong inventory practices create a powerful competitive advantage, enabling you to meet customer demand reliably, operate more efficiently, and scale profitably.

To translate these principles into action, consider this structured approach:

1. Start with an Audit: Begin by conducting a thorough inventory audit using cycle counting (Practice #8). You cannot manage what you do not measure, and this first step provides the baseline data needed for every other initiative.
2. Prioritize Your Efforts: Immediately apply the ABC analysis (Practice #2) to your product catalog. This will instantly clarify where your focus should be. Devote your initial energy to optimizing the inventory management for your top 20% of SKUs that drive 80% of your revenue.
3. Implement Foundational Tech: If you're still using spreadsheets, your next priority is to adopt a real-time inventory tracking system (Practice #1). This is the technological backbone that enables almost all other best practices, from accurate forecasting to multi-channel fulfillment.
4. Establish Core Metrics: Define and begin tracking your key performance indicators (KPIs), such as Inventory Turnover Ratio, Holding Costs, and Stockout Rate. These metrics will tell you if your strategies are working and where you need to make adjustments.

The True Cost of Inaction

It can be tempting to view this level of strategic oversight as a task for "later," especially when you're busy with marketing, sales, and customer service. But the hidden costs of inaction are immense. Every dollar tied up in slow-moving inventory is a dollar you can't use for a new product launch, a critical ad campaign, or strategic hiring. Every lost sale due to a stockout erodes customer loyalty and damages your marketplace ranking.

Adopting these inventory management best practices transforms your stock from a passive, costly necessity into an active, strategic asset. It empowers you to make data-driven decisions that directly impact your bottom line, creating a resilient and scalable business ready for any market condition. The journey from reactive order-taking to proactive inventory optimization is the hallmark of a mature and successful ecommerce brand.
