Shopify Inventory Best Practices Checklist
A scannable checklist of Shopify inventory management best practices — forecasting, metrics, reorder points, counts, and discrepancy prevention in one place.
Most inventory advice arrives as a 2,000-word guide when what you actually need is ten minutes to check what you're already missing. This is that ten minutes: eighteen checks, grouped by theme, each one linking out to the full guide if you need to fix something instead of just confirm it.
Run through it once now, then again every quarter — a checklist that only gets checked once isn't really a checklist. Nothing here is new; it's the same eighteen-odd things phrased as decisions instead of essays.
Forecasting Demand
Forecasting decides how much you order and when — get this wrong and every other practice below is just compensating for it.
- Reorder from real sales velocity, not a gut check. Use average daily sales times lead time plus safety stock, recalculated from a recent 60–90 day window rather than a stale annual average. Full formula: how to calculate reorder points.
- Recheck supplier lead times before trusting the number. A lead time that quietly grew from 10 days to 18 will break a reorder point still built on the old figure, and you won't know until you're already short.
- Review reorder points on a schedule, not once and forever. Sales velocity drifts, suppliers change, and seasons turn — review quarterly at minimum, monthly for your top-selling SKUs.
Tracking the Right Metrics
Metrics tell you which SKUs are actually a problem before a customer tells you first.
- Track turnover and sell-through monthly, not only when something feels off. Both predict stockouts and dead stock ahead of time. Full formulas and what counts as healthy: the metrics worth tracking.
- Check Shopify's own reports before building a spreadsheet. The numbers you need (sell-through, days of inventory, ABC analysis) likely already exist natively. See where to find them.
- Don't assume every report is on every plan. ABC analysis and some deeper inventory reports require the Grow plan or higher — check your own Reports page rather than assuming it's there.
Setting Reorder Points
A reorder point only works if the tracking underneath it is actually switched on.
- Confirm tracking is on before you rely on a reorder point. An untracked variant shows no Available, Committed, or On hand number at all. Here's how to turn tracking on.
- Set a real alert, not just an admin badge. Shopify's low-stock threshold won't email you by default. Set up alerts that actually reach you.
Counting Stock Regularly
Every other item on this list assumes the count it's built on was accurate to begin with.
- Run a stock count on a schedule, not only when a number looks wrong. Here's the full count workflow, from prep through reconciling variances.
- Choose your counting method deliberately. Cycle counting and a full physical count suit different store sizes and SKU counts. Compare both approaches here.
Preventing Discrepancies
Most discrepancies trace back to a process gap, not a mystery — these are two of the most common ones.
- Reserve draft orders the moment you promise a customer stock. An unreserved draft stays fully sellable to anyone else browsing your store at the same time.
- Uncheck "Restock" on refunds for damaged or unsellable returns. It's selected by default, which quietly adds bad stock back into Available. Root causes and fixes.
- Check bundle or kit inventory manually if you sell them. Whether Shopify's native Bundles app decrements component stock automatically isn't something worth guessing at — confirm it directly in your own store before you trust the number.
Multi-Location Hygiene
Running more than one location doubles the ways inventory can quietly go wrong.
- Set up locations before assigning inventory to products. Shopify only stocks a product where you deliberately choose, not everywhere by default. Full multi-location setup.
- Reconcile each location separately during a count. A healthy store-wide total can still hide one location that's badly off.
- Assign each product to specific locations on purpose. A location isn't stocked automatically just because it exists — pick where each SKU actually lives before you rely on any per-location number.
Using the Right Tools
The last habit is choosing tools that make the rest of this list easier to keep, not harder.
- Pick the real adjustment reason, not the Correction default. It's the difference between an audit trail that explains itself later and one that doesn't. Adjustment reasons and mechanics.
- Start with the fundamentals if any term above is unfamiliar. Inventory management fundamentals covers stock states, turnover, and control methods before any of this will click.
Most of this list is a discipline problem, not a tooling problem, until your SKU count grows past what manual tracking can keep up with. There's no shame in staying manual at ten SKUs — the shame is still doing it by hand at four hundred. That's usually the point where stores look at a dedicated forecasting app instead of another spreadsheet tab — StockCue is ours, and it computes most of this list's numbers for you rather than asking you to maintain them.
STOCKCUE
Run this checklist quarterly, not once — sales velocity drifts and yesterday's reorder points won't stay accurate forever. StockCue automates the forecasting and alerting half of this list, and forecasting itself is included on every plan, including Free.
