How to Reduce Stockouts on Your Shopify Store
Stockouts can come from changing demand, late deliveries, or incorrect inventory records. These six checks help you see the problem earlier and choose a response.
1. Check the inventory record
Compare the stock you can physically sell with the quantity recorded for the right location. Investigate missed receipts, unrecorded movements, and discrepancies before raising a reorder quantity. More purchasing will not fix an incorrect location assignment.
2. Use realistic supplier lead times
Track the time from an accepted order to usable stock on the shelf, including transit and receiving. Review unusual delays separately from normal deliveries. Revisit the planning lead time when your supplier’s performance or shipping method changes.
3. Review sales velocity
Average daily sales provide a starting point. In a simplified example, 300 units sold over 30 days equals 10 units per day. Check whether promotions, stockouts, cancellations, or new products make that average less representative of upcoming demand.
4. Set an explicit buffer
A basic planning threshold is expected demand during lead time plus a safety buffer. For example, 10 units per day over a seven-day lead time uses 70 units; a chosen 20-unit buffer brings the threshold to 90. These are illustrative inputs, not a recommendation for every SKU.
Choose the buffer based on demand variability, supplier reliability, the consequences of running out, and the cost of holding extra stock. Revisit it when those conditions change.
5. Check what is already on order
Inspect open POs and the quantities still outstanding before placing another order. Consider arrival dates: stock that arrives after the projected shortage will not prevent that shortage. Avoid treating an unaccepted draft as a confirmed delivery.
6. Turn review into a repeatable task
Use alerts and a regular review schedule to identify products needing attention. Assign someone to check supplier availability, cost, and quantities before an order is sent. Track whether the recommendation led to an accepted order and a completed receipt.
StockrHub can show stock coverage and replenishment suggestions, and reorder analysis can create or update draft POs. Configured automation has its own activation requirements and effects; read the automation guide before enabling it.
Start with a small group
Choose a few important SKUs with understandable sales patterns. Check the records, configure planning inputs, and compare recommendations with actual demand and deliveries. Expand when your team can explain the results. No forecast or alert eliminates every stockout.
