What is accounts payable automation?

Definition

Accounts payable automation is software that handles supplier invoices from receipt to payment: it captures invoice data, matches invoices to purchase orders, routes them for approval, schedules and makes payments, and posts the entries to the general ledger. It replaces manual keying, paper approvals and paying suppliers one by one in the bank portal.

How accounts payable automation works

An invoice arrives by email, supplier portal, e-invoice or post. The software reads the supplier, dates, amounts, tax and line items, checks the supplier against the vendor master and flags possible duplicates. Invoices with a purchase order are matched to the order and the goods receipt; others are coded to accounts and cost centres, often with suggestions learned from past coding. Approval rules route each invoice by amount, entity or department. Approved invoices go into a payment run by due date, paid by bank transfer, ACH, card or cheque, and the payment and invoice post to the ledger. BILL serves small and mid-sized businesses, Tipalti focuses on global payables and mass payouts, and Coupa covers procurement through to payment for large enterprises.

Common questions

What is the difference between AP automation and procure-to-pay?+

Accounts payable automation starts when the supplier invoice arrives. Procure-to-pay also covers what happens before it: purchase requests, approvals, purchase orders and receipt of goods. Many AP products now include some purchasing, and procurement suites include AP.

Does AP automation replace the accounts payable team?+

No. It removes data entry, chasing approvals and building payments by hand. The team still sets up suppliers, resolves exceptions such as price differences and missing purchase orders, and reviews payments before they are released.

Which invoices can AP automation process without anyone touching them?+

Invoices from known suppliers that match a purchase order or a recurring pattern, pass duplicate and tax checks and fall within approval rules. The share processed this way is measured as the touchless rate.
