Dutchie
Connect a Dutchie POS key and Purchase Pro keeps rooms, employees, and vendors in sync, and receives inventory against the order.
Integrations
The systems you already run, on the purchasing record
Point of sale, track-and-trace, licensed wholesale, and the ledger stay connected to the location that is buying. Agents connect the same way: with that user’s permissions.

A public API for purchasing data, and a supplier product-sync API for catalog updates.
