Shopify inventory sync — sell everywhere, count once

Running a shop and a Shopify store usually means two stock numbers that slowly drift apart. StockFlow makes itself the single source of truth: paid Shopify orders flow in as sales, stock levels flow back out, and a built-in audit continuously proves the two systems agree.

Paid orders become sales automatically

A paid Shopify order is ingested as a sale — stock deducted at the right location and the full accounting posted — so online revenue lands in your books with no re-keying.

Stock levels sync back out

As you sell, receive or transfer in StockFlow, updated quantities are pushed to Shopify, so your storefront shows what you can actually fulfil.

A mismatch audit you can trust

A built-in check compares StockFlow and Shopify and surfaces any discrepancy, so drift is caught early instead of at stock-take.

Resilient by design

Syncs run through a job queue; if one fails it’s queued for one-click retry rather than silently lost — and every action is logged.

Frequently asked questions

Does my Shopify store keep working?
Yes — it keeps running, with StockFlow as its source of truth. Paid orders flow in as sales (stock deducted, accounting posted) and stock levels flow back out to Shopify.
What happens if a sync fails?
Syncs run through a queue; a failed sync is queued for one-click retry rather than lost, and a built-in mismatch audit proves the two systems agree.
Does an online sale post accounting too?
Yes. An ingested Shopify sale posts the same balanced double-entry as an in-store sale — revenue, VAT, COGS and stock.
Can I sell in-store and online from one stock pool?
Yes — both channels draw from the same per-location inventory, so you count once and sell everywhere.
