Inventory advice for small brands usually comes from the warehouse world — barcode scanners, bin locations, cycle counts. If you're a founder making things in small batches, most of that is noise. You have exactly three inventory problems worth solving:
- Don't oversell — promising the same 20 units to your website and two wholesale accounts.
- Don't overmake — producing what isn't selling while what is selling sits out of stock.
- Know what to make next — production planning driven by real demand, not anxiety.
The minimum viable inventory system
One sheet, four columns per SKU: on hand, committed (sold but not shipped — including wholesale orders the moment they're confirmed!), available (on hand minus committed), and reorder point (the level at which you start making more, set by how long a batch takes you). Update it at two moments only: when an order is confirmed and when a batch is finished. That's it. The brands that get burned aren't the ones with simple systems — they're the ones whose wholesale orders never make it into any system, so "available" is fiction. (This is why order capture is upstream of inventory: our order management guide covers that pipeline.)
Signals that beat software
Sell-through per account tells you what to make more of — "Foxglove sold through the mugs in 3 weeks" is a production instruction. Seasonal memory beats forecasting tools at small scale: last Q4's numbers, written down, are your best plan for this Q4. And your wholesale case packs (see the glossary) should match your batch sizes — friction between the two quietly costs hours.
When to graduate to real software
Honest answer: when you have multiple sales channels pulling from one pool of stock and the sheet is wrong more than once a month. Shopify's inventory is a fine spine for DTC + wholesale if your wholesale orders actually get entered. That "if" is the weak link — which is why the highest-leverage inventory fix for most founders isn't inventory software at all; it's making wholesale orders flow into the system the moment they're spoken or emailed, automatically. (That's Mira's job — and a native Shopify inventory sync is on our roadmap; add your email there if you need it and the most-wanted feature gets built first.)
