Purchase-to-pay
What is purchase-to-pay?
Purchase-to-pay is the purchasing chain from order to payment: purchase order, receipt, purchase invoice, approval and payment to the supplier.
In many organisations this is still surprisingly manual: purchase invoices are retyped, checked against the order and the receipt, and sent past one or more approvers. Finance automation with AI takes that manual work out.
AI can read purchase invoices, pre-code them, check them against the purchase order and queue them for approval. Deviations in amount or quantity are flagged before anything is paid.
The sales side is called order-to-cash.
