Inventory how-to

Why inventory accuracy matters

Inventory accuracy means the stock number in your store admin matches what is actually on your shelf.

Short answer: Inventory accuracy means the stock number in your store admin matches what is actually on your shelf. If it drifts, you oversell, understock, and misjudge what to reorder. Accuracy is the foundation that any forecast or reorder plan depends on.

What inventory accuracy actually means

It means that when your store admin says you have 40 units of a variant, you have 40 units, not 34 or 52. Small gaps build up over time from damaged stock, miscounts, returns, or receiving errors that never get corrected.

What happens when it breaks down

If your recorded stock is higher than reality, you sell items you do not have and have to cancel or delay orders. If it is lower than reality, you stop selling an item that is still sitting on the shelf, or you reorder stock you do not need. Either way, any sales forecast or reorder suggestion built on that wrong number will be wrong too, no matter how good the math behind it is.

Where the errors creep in

Common sources are partial deliveries that get marked as fully received, manual stock adjustments that are never logged, damaged or lost items that are not written off, and counts that only happen once a year. Each of these pushes your recorded number further from reality until something forces a correction, usually a customer complaint or a surprise stockout.

Keeping it under control without full stocktakes

You do not need a full warehouse count every month to stay reasonably accurate. Spot-checking your fastest-moving and highest-value variants regularly catches most of the damage early. Correcting stock as soon as you notice a discrepancy, rather than waiting for a scheduled count, keeps the gap small.

Step by step

  1. Spot-check your top 20 variants by sales volume every few weeks, not just once a year.
  2. Record every partial delivery exactly as received, not as fully received.
  3. Write off damaged, lost, or returned-and-unsellable stock the day you find it, not at month end.
  4. Investigate any variant where sales suddenly stop or spike with no obvious cause, that is often a sign of a stock error.
  5. Keep one person responsible for stock adjustments so changes are not made inconsistently by different staff.
  6. Review stock accuracy for any SKU before you place a large reorder for it.

Worked example

A store shows 60 units of a candle on hand, but 10 were damaged in a warehouse spill three weeks ago and never written off. The real count is 50. Daily sales for that candle are 3 units. With the wrong number, days of stock look like 60 / 3 = 20 days. With the correct number it is 50 / 3 = 16.7 days, which is closer to when a reorder should actually go out. The 3.3-day gap is small per SKU, but across hundreds of variants it adds up to real stockouts and wasted orders.

How SteadyShelf helps

SteadyShelf forecasts and reorder suggestions are only as good as the stock numbers in your store, and it relies on your store admin's inventory count rather than doing its own stocktakes or cycle counts. It does handle receiving, including partial deliveries, accurately into Shopify, which closes off one common source of drift. For counting and correcting errors elsewhere, that still has to be a manual process on your end.

FAQ

How often should a small store do a full stocktake?

There is no fixed schedule that fits every store. Many small stores do a full count once or twice a year and rely on spot-checks of high-value or fast-moving items in between. The right frequency depends on how often you catch discrepancies and how much a stockout or overstock costs you on a given SKU.

Does SteadyShelf fix inventory accuracy problems automatically?

No. SteadyShelf reads the stock numbers already in your store and uses them to forecast and suggest reorders. It does not run stocktakes or cycle counts, so if your underlying numbers are wrong, you need to correct them manually in your store admin.
