Stop selling what you no longer have
Overselling is the moment two people buy the same item — because one channel sold it and the others didn’t find out in time. You refund one of them. You apologise. You take the hit on your seller rating. And unless something changes, it happens again next week.
It isn’t carelessness. It’s the gap between a sale happening on one channel and every other channel finding out. If eBay sells your last jacket but Shopify still shows it in stock for even a few minutes, someone can buy a jacket you no longer have.
Why it keeps happening
Every platform tracks stock on its own. Shopify counts its way, eBay counts its way, Etsy counts its way — and none of them talk to each other. A sale or an edit on one never reaches the rest, so the numbers drift apart. The more places you sell, the wider the gap, and the more often it catches you out.
Most sellers try to hide from the problem by holding stock back — listing 3 when they have 5, keeping a buffer "just in case." That loses you real sales, ties up stock you could be selling, and still fails on the last unit.
How Stoki One prevents it
Stoki One holds one true stock number for every item, underneath all your channels. When something sells anywhere, Stoki corrects every other connected channel within seconds — not on a schedule, but as it happens.
You set the real number once. Stoki guards it. You can list your full stock everywhere, confidently, because the moment a unit sells on one channel, it disappears from the others before the next buyer can reach it.
- One true number for every item, across every channel you sell on
- Corrected everywhere within seconds of a sale
- No more holding stock back "just in case"
- Refunds and returns restore stock only when the item actually comes back
Who it's for
Sellers who list the same items across two or more channels — Shopify, eBay, Etsy, WooCommerce, and in person — and who are tired of refunding orders they can’t fulfil.
Common questions
- Does it work in real time?
- Stoki corrects every connected channel within seconds of a sale — not on a batch schedule.
- What about in-person sales?
- Sell something at a market stall or over the counter with Stoki One POS, and your online stock drops everywhere straight away.
- Do refunds add stock back automatically?
- Only when the item genuinely returns. Stoki treats the money and the stock as two separate things, so it never adds back stock you don’t physically have.
One system. One app. One true number — everywhere you sell.
