The hidden cost of stockouts and overstocking

Inventory management can feel like a constant tightrope walk. On one side, you risk the frustration and lost sales of a stockout. On the other hand, the financial drain and wasted space of overstocking. It's a delicate balance that, if not managed correctly, can significantly impact your bottom line and customer satisfaction. Running out of critical materials can stall production lines, delay shipments, and erode customer trust.  But what if there was a way to navigate this challenge with confidence, ensuring you always have just the right amount of product on hand? According to McKinsey, companies can reduce inventory carrying costs by up to 20% through better planning.

An inventory replenishment workflow provides structure to prevent these risks. It combines automated triggers, clear approval thresholds, and streamlined vendor coordination so teams can act with confidence. Instead of reacting to shortages, businesses can anticipate demand, manage risks, and optimize capital usage.

This blog post will unveil the ultimate inventory replenishment workflow designed to help you avoid both stockouts and overstocking. We'll dive into practical strategies, essential tools, and best practices that will transform your inventory process from a headache into a finely tuned operation. Get ready to optimize your stock, boost efficiency, and keep your customers happy.

Triggers and signals: When does replenishment start

The first step in any effective replenishment process is recognizing the right time to act. This isn't just about waiting until a shelf is empty; it's about using intelligent triggers to maintain optimal stock levels.

Minimum and maximum levels (Min/Max)

This is the most fundamental replenishment trigger. Businesses define stock “floors” (minimum) and “ceilings” (maximum) for each item.

Minimum threshold: When items drop below this pre-set level, the workflow automatically triggers a replenishment order. This prevents stockouts.

Maximum threshold: Similarly, orders pause if inventory approaches the maximum level. This prevents overstocking, which ties up cash and warehouse space.

Reorder Point (ROP)

A more dynamic approach than a simple minimum level, the reorder point formula considers both demand and supplier lead time. It's calculated as:

ROP = (Average Daily Usage x Average Lead Time in Days) + Safety Stock

When inventory hits this point, it’s the signal to order more. This ensures new stock arrives just as you're about to run out, factoring in how long it takes your supplier to deliver.

Material requirements planning (MRP)

More advanced organizations rely on MRP systems. These software solutions go beyond simple counts and calculate replenishment needs based on:

Demand forecasts: Predicting future sales.

Production schedules: Knowing what materials will be needed for manufacturing.

Supplier lead times: Understanding how long it takes to get new stock.

This method ensures replenishment is tied directly to actual and projected business activity, not just static inventory levels.

Example in action

Imagine a logistics firm managing vehicle spare parts. Their system uses a reorder point trigger. For brake pads, the ROP is 200 units. When stock dips below this number, the workflow automatically sends a replenishment request. With integrations into their vendor portal, the supplier is notified instantly, kicking off the delivery process and ensuring continuous availability without manual intervention.

Approval thresholds: Keeping spending under control

Not every replenishment signal should immediately result in a purchase order. This is where approval thresholds come in, creating essential guardrails for financial oversight and preventing budget blowouts.

By setting up an approval workflow, you can automate routine purchases while flagging larger, more significant expenses for review. For example, a company might allow automatic replenishment for any order up to $5,000, but anything higher requires management review. This tiered approach ensures agility for everyday needs while preventing large, unchecked financial commitments.

Key benefits of setting approval thresholds include:

Financial control: Prevents overspending and ensures procurement aligns with budget constraints.

Risk mitigation: Adds a layer of review for high-value orders, reducing the risk of costly purchasing errors or fraudulent activities.

Strategic oversight: Gives management visibility into significant expenditures, allowing them to make more strategic decisions about inventory investment.

With modern platforms like Moxo, these approval workflows can be streamlined. Approvals can be routed dynamically to the right person, reminders can be automated to avoid delays, and every decision is tracked in a clear audit trail. This protects compliance and accountability while keeping the procurement process responsive and efficient.

Vendor POs and confirmations: Closing the loop for optimal inventory

Once a requisition for inventory is approved, purchase orders (POs) are generated and sent to vendors. But the workflow doesn't stop there. Confirmations from suppliers are equally critical for effective inventory management. They validate order acceptance, expected delivery dates (crucial for replenishment timelines), and agreed-upon terms, preventing stockouts or overstock situations. Without prompt and accurate confirmations, organizations risk unpleasant surprises, impacting their ability to meet demand.

Using secure document sharing and e-signatures within a client portal, businesses can exchange POs and confirmations seamlessly. This not only reduces email clutter but also creates a single source of truth for inventory orders, accessible to both internal teams and external partners. This digital trail is vital for tracking replenishment orders, reconciling stock, and ensuring your inventory levels remain perfectly balanced.

‍

Handling exceptions and escalations: When things go wrong

Even the best-laid plans can go awry. Late shipments, damaged goods, or sudden spikes in demand are inevitable disruptions in any supply chain. That’s why a robust replenishment workflow must include clear escalation paths for when things don't go as planned.

For example, if a vendor misses a delivery window, the workflow can automatically trigger an alert and escalate the issue, perhaps by notifying a manager or even placing an order with a backup supplier. Similarly, if a quality control check flags a shipment as damaged, the system can automatically route the issue to the appropriate team to arrange a return and reorder.

Key exceptions to plan for include:

Supplier issues: Late deliveries, partial shipments, or quality problems.

Logistical disruptions: Shipping delays, customs holds, or warehouse receiving errors.

Inventory discrepancies: Stock counts not matching system data (e.g., due to theft, damage, or misplacement).

Demand fluctuations: Unexpected surges or drops in sales that throw off forecasts.

By building automated exception handling into your workflow, these problems don't get lost in someone's inbox. Instead, they are addressed immediately with clarity and accountability, preventing minor hiccups from turning into major stockouts or overstock situations.
