   BILL (formerly Bill.com) - the default pick for small businesses whose real problem is accounts payable: invoice capture, multi-step approvals, vendor management, and AP + AR in one place.
5. QuickBooks mentioned
   Deepest QuickBooks/Xero integration of the group, and the one accountants and bookkeepers know best, which matters if an outside firm touches your books.

10. Stampli mentioned

    Plooto - flat-rate pricing rather than per-user, which is the cheapest path once you have several people who need access but low invoice volume.
13. Zoho Books mentioned
    Zoho Books / QuickBooks Online bill pay - worth naming because plenty of small businesses don't need a separate AP tool at all.

The answer, as recorded

## Short answer For most small businesses: **BILL** if AP is the actual job, **Ramp** if you want AP bundled free with corporate cards, **Melio** if you're tiny and just need bills paid. **1. BILL (formerly Bill.com)** - the default pick for small businesses whose real problem is accounts payable: invoice capture, multi-step approvals, vendor management, and AP + AR in one place. Deepest QuickBooks/Xero integration of the group, and the one accountants and bookkeepers know best, which matters if an outside firm touches your books. Costs real money per user/month, and that's the tradeoff. ([BILL comparison](https://www.bill.com/blog/best-accounts-payable-software), [fitsmallbusiness](https://fitsmallbusiness.com/bill-com-vs-melio/)) **2. Ramp Bill Pay** - best value if you also want corporate cards and expense management. AP is included free because Ramp makes money on interchange, and it leans hard on AI for invoice coding. Best when you want one system for cards + bills; weaker if you need complex AP-specific approval hierarchies without adopting the whole spend platform. ([Tipalti: Ramp vs BILL](https://tipalti.com/resources/learn/ramp-vs-bill/)) **3. Melio** - for solo operators and teams under ~10 people. Free ACH, no subscription, pay vendors by card even when they only accept checks. Deliberately skips AI coding, PO matching, and deeper ERP integrations, so you will outgrow it if invoice volume or approval complexity climbs. ([Tipalti: Melio vs BILL](https://tipalti.com/resources/learn/melio-vs-bill/)) **4. Stampli** - pick this when approvals are the bottleneck. It centers everything on a communication thread attached to each invoice, so the back-and-forth with approvers stops living in email. Strong AI coding, and it fits companies with messier internal review chains. ([Xelix roundup](https://xelix.com/resources/accounts-payable-solutions/best-13-accounts-payable-software-solutions)) **5. ApprovalMax** - narrow but excellent if you're already on Xero or QuickBooks and only need a real approval layer bolted on, not a whole new AP system. ([ApprovalMax](https://blog.approvalmax.com/accounts-payable-software-for-small-business)) **6. Plooto** - flat-rate pricing rather than per-user, which is the cheapest path once you have several people who need access but low invoice volume. **7. Zoho Books / QuickBooks Online bill pay** - worth naming because plenty of small businesses don't need a separate AP tool at all. If you're under ~20 bills a month with one approver, the AP features already inside your accounting software are enough, and adding a fourth system is a net loss. ## One caveat on the sources Several of the "best AP software" listicles that dominate these search results are published by vendors in the category - Ramp, BILL, and Tipalti all run comparison blogs that rank themselves favorably. I've cross-read them against each other, but treat any single one as marketing rather than a review. ## How I'd decide Under 50 invoices/month and one approver → Melio or your existing accounting software. Want cards and bills unified → Ramp. Real AP volume, multiple approvers, an outside bookkeeper → BILL. Approvals specifically are what's broken → Stampli or ApprovalMax.
