Overselling — selling a product that's already gone — leads to cancellations, bad reviews and marketplace penalties. The cause is almost always the same: stock updated by hand and too late.
How auto-sync works
The platform regularly checks supplier availability and instantly updates it everywhere. Out of stock — the listing hides itself, without your involvement.
What you get
- No orders for items you don't have.
- Fewer cancellations and returns.
- A higher seller rating and less risk of bans.
Tip
Set the update interval to match your turnover: check bestsellers more often. Availability stays accurate.
Step-by-step plan
- Check how your supplier sends availability: as a quantity or a text status.
- Set up an availability rule so text statuses are interpreted correctly.
- Choose an update interval based on how fast your products sell.
- Enable automatic hiding of zero-stock products on all marketplaces.
- Once a week, check when the feed last updated so you catch failures early.
The most common mistake
Sellers often set infrequent stock updates, such as once a day, to 'avoid overloading the system'. That's enough for slow movers, but bestsellers can sell out at the supplier by lunchtime. As a result, evening orders have to be cancelled. Set the frequency separately: update popular items more often and keep the standard interval for the rest. This removes most overselling at no extra cost.
What overselling really costs
Every cancelled order is more than a lost sale. Marketplaces lower a seller's rating for a high cancellation rate, and your products appear lower in search. Repeated violations can get the account restricted. A buyer who never received the item rarely comes back.
That's why accurate stock isn't about convenience — it's about your store surviving on the marketplace.
FAQ
How often is stock updated?
The interval is configurable — from 15 minutes to a day. For bestsellers we recommend more frequent updates.
What if the supplier didn't update the feed?
The platform uses the latest data received and shows in the dashboard when the feed was last updated, so you spot the problem in time.
Is the product hidden automatically?
Yes. When stock hits zero, the product is marked out of stock on every connected marketplace.
