The full list
It depends on your accounting system and volume: BILL, Ramp and Melio suit small teams that mainly pay bills, Stampli, AvidXchange, Medius and Coupa suit quote-based mid-market and enterprise buyers, and Tipalti suits global payouts. Aequo AP fits SMB and mid-market teams on QuickBooks Online, Xero, FreshBooks, Zoho Books or Business Central that need purchase-order matching at a flat price.
By accounting system
Guides for every accounting system Aequo AP connects to live today: QuickBooks Online, Xero, FreshBooks, Zoho Books or Business Central.
- The best AP automation software for QuickBooks Online
For payments, BILL, Ramp and Melio sync with QuickBooks Online; ApprovalMax adds approvals, Dext captures bills, and Stampli, Ottimate and Aequo AP match invoices to purchase orders before the bill posts. On QuickBooks Advanced, the included Bill Pay Elite approvals may be enough for a small team.
- The best AP automation software for Xero
It depends on the gap: ApprovalMax is the approval specialist on Xero, Dext and Hubdoc capture bills, BILL, Ramp and Melio pay them, and Aequo AP combines capture, PO matching and approvals in one queue. Small Xero users may need none of them, because Xero’s own document capture and bill pay cover simple AP.
- The best AP automation software for Business Central
Continia Document Capture is built specifically for Business Central, and Stampli, Medius, Tipalti, BILL and Ramp each list a Business Central integration; Aequo AP connects too, with published pricing and draft purchase invoices it never posts. Start with Business Central’s own approval workflows and Payables Agent, which may cover simpler AP.
- The best AP automation software for FreshBooks
For most FreshBooks users the best option is FreshBooks itself: Premium and Select include bills, bill scanning and Bill Pay. Few AP tools connect to FreshBooks directly; BILL offers file import and export, and Aequo AP writes approved bills into FreshBooks when you need approvals and duplicate checks in front of it.
- The best AP automation software for Zoho Books
Start with Zoho’s own BillPay add-on, which scans bills, matches them to purchase orders and adds approvals; Dext captures documents into Zoho Books and Ramp syncs bills and payments for US companies. Aequo AP is the option when you want matching, approvals and exceptions in one queue, since most payment-led AP tools do not list Zoho Books.
