One true stock number, everywhere you sell
Sellsync is event-driven: the moment a sale lands on any channel, your shared stock figure updates and every other channel follows within seconds — so overselling stops.
A sale on one channel updates them all
Event-driven sync means no overnight batch jobs and no manual re-counting — each sale is handled as it happens.
A sale lands
A buyer checks out on any connected channel, or you ring up a sale at the POS.
Shared stock drops
Sellsync decrements the one master stock figure for that SKU straight away.
Every channel updates
The new quantity is pushed back out to all your channels within seconds.
The real cost of overselling
Selling the same last unit twice isn't just an awkward email. On marketplaces, a cancellation ripples into penalties and lost visibility — the things that quietly cap your growth.
Cancelled orders
Selling the last unit twice forces a cancellation — and a let-down buyer.
Account-health penalties
Marketplaces penalise cancellations and late ships, hurting your store's standing.
Lost Buy Box & ranking
Weak fulfilment metrics push listings down the results and cost you the Buy Box.
Stock control that keeps up with you
Central stock pool
One master quantity per SKU feeds every channel and your POS.

Bundles & variants

Record deliveries, damages, and counts — all with a full history.
Purchase orders & restock
