Securely link your Square and Shopify accounts. No code, no developers.

Everything stays matched, both directions

Your inventory, products, and variants come across in a one-time bulk sync, then inventory stays matched in real time between Square and Shopify. If anything ever looks off, sync history and one-click rollback have your back.

Not every inventory tool works the same way — here’s what to look for, and what OneKeepr does:

More than sync — the inventory platform behind your Shopify store

Sync is the foundation. OneKeepr also runs your product hub, purchasing, vendors, reporting and multi-location — use it on its own or connected to Shopify.

Stop overselling. Stop double entry.

When your POS and online store don’t talk to each other, you either oversell items you don’t have or burn hours keying the same change into two systems. OneKeepr removes the manual work and keeps your numbers honest — a sale anywhere updates everywhere.

Simple pricing, 7-day free trial

Starter $29/mo for smaller catalogs · Growth $49/mo for larger stores.

Questions

Does it sync both ways?+

Yes. Changes in Square update Shopify, and changes in Shopify update Square, in real time.

Does it sync full products, or just stock counts?+

More than counts. Inventory, products and variants sync between Square and Shopify — not just quantities.

Do I have to pick a “master” or source of truth?+

No. There’s no master platform to choose — both stay in sync automatically, so you can edit in whichever system is handy.

How fast does it sync?+

Inventory changes are real time — seconds, not hours. Your first full catalog import runs once in the background.

Will my price go up as I get more orders?+

No. It’s one flat monthly price, no matter how many orders you process.

Will it prevent overselling?+

Yes. Your stock stays matched across both, so you won’t sell what you don’t have.

Do I have to move my catalog manually?+

No. A one-time bulk sync brings your existing products in.

What if a sync goes wrong?+

Every change is logged, and you can roll back with one click.

Is there a contract?+

No. It’s month-to-month — cancel anytime.
