Every invoice finds its paperwork, however it arrives
Five purchasing shapes are derived from what you upload rather than fixed in advance — invoice to order, invoice to order to receipt, invoice to receipt, order to proforma, contract to invoice. Anything unusual becomes its own flow rather than being forced into a shape that does not fit it.
- └─A purchase order that arrives after its invoices still pulls them in
- └─An invoice authorised by a contract rather than an order sits in the same queue
- └─Duplicate numbers are caught before a second payable can form
