Inventory reconciliation audit
Your sync app says everything is fine. Meanwhile a listing on Etsy is selling stock you don't have. Parity reads both sides every day and tells you the moment the numbers stop agreeing.
None of these throw an error. That's the whole problem — your sync app reports success while the stock drifts apart underneath it.
One-way sync
You change a quantity on Etsy. It never reaches Shopify. Nothing warns you. Sellers routinely find out months later, after the damage is done.
Restock lag
Quantity syncs, price doesn't. The listing goes live again at whatever it cost the last time you restocked, and you sell at a loss until you notice.
Silent zero-out
One bad sync run empties every listing, or fills them with stock you never had. By the time support answers, you've already oversold.
Read-only. It never writes to your store or your listings, so it can't be the thing that breaks them.
Connect
Authorise Shopify and your channel. Two clicks each. No data leaves your account except the quantities we compare.
Watch
Channel orders are checked the second they're paid. A full catalogue reconciliation runs daily to catch the slow drift nothing else reports.
Tell you
Which item, which channel, what each side thinks it has, and when they diverged. No dashboard to check. You only hear from us when something is wrong.
You already pay for one. It's probably fine most of the time — and when it isn't, it doesn't tell you.
Parity sits next to whatever you already use. You don't migrate, you don't rebuild your listings, you don't change anything. If your sync app is working, you'll never hear from us and you'll know it's working. If it stops, you'll know that too — the same day, not at the end of the month.
Works alongside every major Shopify multichannel app.
