Product/Invoices

An invoice inbox that runs itself.

AI-powered accounts payable. Invoices land in a dedicated inbox, get read and matched to the PO, route through approval, and push to Xero. Unmonitored by design, so nothing sits unprocessed.

From a dedicated inbox to Xero, without you touching it.

01 · Receive

A dedicated inbox that monitors itself.

Every company gets a unique invoice email address. Suppliers send invoices straight to it, and the inbox reads everything that lands, whether or not anyone is watching.
