Reliably connect Square POS to BigCommerce — real-time inventory, product and cost sync, purchase orders, and reporting.

Reliably connect your point of sale to BigCommerce and keep both in step, automatically. When you sell in-store, your online stock updates. When inventory arrives or moves, every channel reflects it — so you stop overselling and stop editing the same product in two places.

OneKeepr goes beyond keeping stock accurate. It gives independent retailers a real operations layer: one product hub for titles, variants, pricing, and cost; purchase orders and receiving that keep costs and vendors attached to every SKU; multi-location stock and transfers; and reporting on sales, margin, vendors, and reorder points.

Built for independent retailers who run their store on a modern POS and sell on BigCommerce online, and need both to stay accurate — without the manual work.
