Frequently asked questions

Do I have to switch off Shopify or Square?

No. You keep both exactly as they are. OneStock just keeps the stock counts in sync between them.

How is this cheaper than Lightspeed or the big POS suites?

Those replace your whole setup and start around $89/mo. OneStock does one job — sync — for $29 and changes nothing else.

What about WooCommerce?

On the roadmap. Same engine, so WooCommerce + Square is next after Shopify.
