Accounts payable automation software handles the other half of the invoice cycle — the bills your company owes rather than the ones it is owed. A supplier invoice arrives by email or PDF, someone keys it into the ERP, someone else has to approve it, and eventually a payment goes out by ACH, card, wire or paper check. These platforms capture the invoice automatically, code it against your chart of accounts, route it through an approval chain, match it to a purchase order and receipt where one exists, execute the payment, and write the whole thing back to the accounting system. Three things separate the products more than feature lists do. First, how deep the ERP integration goes: a QuickBooks-only bill-pay tool and a platform certified against seventy ERPs including SAP and Oracle solve different problems. Second, who the payees are — paying two hundred domestic suppliers is a different job from onboarding thousands of overseas contractors who need W-8 forms and local payment rails. Third, the pricing model, which ranges from published per-seat tiers with per-transaction fees at the small-business end to quote-only platform contracts where implementation is its own line item.
Small-business bill pay with a genuinely free tier and published per-transaction fees, now owned by Xero after the $2.5B acquisition completed in October 2025.
Global payables built around the payee side — supplier self-onboarding, W-8/W-9 collection and 1099/1042-S filing, paying into 200+ countries; from $99/month plus transaction fees.
