AP Automation Pricing Compared (2026): 10 Tools at 200 Bills a Month

For a company paying 200 vendor bills a month, 20% of them to suppliers abroad, with 3 people approving payments, billed monthly, Ramp's free AP plan is the cheapest at $894.40 a month ($10,732.80 a year) once its per-payment fees are counted, verified on Ramp's pricing and fee pages in September 2026. Melio is the closest runner-up for a team that wants a flat per-seat price instead of a fee schedule, at $915 a month.

CFOpresso data: Toolradar, the software directory we run, has evaluated 265 accounting tools for its ranking, last updated September 2026. Of the 10 AP tools this brief set out to price at the same 200-bill scenario, only 4 could be ranked on a published, dated, USD figure; the cheapest and priciest of those 4 sit $4,267.20 apart a year for the identical job of paying the same 200 bills.

The scenario, and the math

The scenario is a company that pays 200 vendor bills a month, 40 of them (20%) to suppliers outside the US, with 3 people who need to approve a bill before it pays, billed monthly rather than annually. A tool only earns a spot in the ranking if it can actually clear all three conditions on a published price: enough approver seats, a domestic payment method, and an international payment method, all confirmed on the vendor's own pricing or fee page.

Ramp's math is the cleanest because its AP plan itself is free. Its Free tier covers 3 users at $0 each, so the entire monthly bill is transaction fees: 160 domestic bills at $0.59 per standard ACH payment, plus 40 international bills at $20 per SWIFT USD wire, comes to $94.40 in ACH fees plus $800 in wire fees, for $894.40 a month, or $10,732.80 a year. That fee schedule took effect in June 2026; Ramp's marketing still leans on "free wires," which is only true when the payment is funded from a Ramp Checking Account rather than an outside bank.

Ramp: free AP plan, but the fee schedule now does the pricing

Ramp's AP product carries no subscription cost at the tier this scenario needs, confirmed on Ramp's pricing page: the Free plan already includes invoice extraction, configurable approval workflows and bill payment by ACH, card, check or wire, at $0 per user. What changed in 2026 is the fee schedule underneath it. Ramp's own fee breakdown now lists a standard ACH payment at $0.59, a domestic wire at $15 and an international SWIFT USD wire at $20, effective June 1, 2026, with those fees waived only when the payment is funded from a Ramp Checking Account rather than an outside bank. For a company routing payments from its existing bank, the "free" plan still runs $894.40 a month on 200 bills. It stays the cheapest option in this table, but the margin over Melio is a lot thinner than the sticker price suggests.

Melio: the flattest fee, undercut by its per-seat add-on

Melio's Core plan is built for exactly this kind of approval workflow, confirmed on Melio's pricing page: $25 a month covers the first user, with each additional approver added at $10 a month, so 3 users run $45 a month before a single bill is paid. Melio's own transaction-fee schedule charges $0.50 per domestic ACH payment past the plan's 20 free ones and a flat $20 per international payment settled in USD, both lower or equal to Ramp's rates. What keeps Melio from taking the top spot is that $10-per-seat add-on: three approvers cost more than Ramp's free seats, enough to land Melio $20.60 a month behind Ramp even with a marginally cheaper domestic ACH rate.

Where the ranking flips

This ranking holds at 200 bills a month with a fifth of them paid abroad. It flips once volume climbs, because Ramp, Melio and BILL all charge per bill while Routable charges a flat monthly fee regardless of how many bills move through it. Using this scenario's 80/20 domestic-to-international split, Ramp's fees average $4.47 per bill, so dividing Routable's flat rate by that blended fee puts the crossover at roughly 280 bills a month, the point where Routable's flat price becomes the cheaper choice. A company at 200 bills today that expects to grow past that mark should model Routable's flat fee against its own growth curve rather than defaulting to the per-transaction tools that win at today's volume.

Hidden costs to budget for

• Ramp: the per-wire and per-ACH fees in the table above are both new as of June 2026 and apply to every payment funded from an outside bank; routing bills through a Ramp Checking Account is the only way to waive them, confirmed on Ramp's fee schedule.
• Melio: each approver past the first costs $10 a month on every paid plan, and its international payment fee (see table above) kicks in once the free monthly ACH allotment (5 on Go, 20 on Core) runs out, confirmed on Melio's pricing page.
• BILL: an international USD wire costs $19.99 even though BILL's international FX wire is fee-free (the FX spread isn't published as a flat number), and a failed ACH charged back after the vendor has already been paid costs $50, confirmed on BILL's pricing page.
• Routable: Growth has no lower self-serve tier, so a smaller team pays the full monthly fee or nothing; Scale and Enterprise both require a sales call, confirmed on Routable's pricing page.
• QuickBooks: Bill Pay does not send international vendor payments at all, so it can't cover the 20% of this scenario's bills going abroad without pairing it with a separate international-payment tool.
• Tipalti, Stampli, AvidXchange: none of the three publishes a full price for this scenario. Tipalti's pricing page lists Accounts Payable "starting at $99/month" but doesn't disclose the per-invoice or per-payment transaction fees needed to total a 200-bill month, directing that to "your custom quote"; Stampli's pricing page carries no dollar figure, only a "Request a Quote" button; AvidXchange's site has no pricing page at all and names no price anywhere else on the site. All three are excluded from the ranked table above because their published pages don't confirm a total cost at this scenario.
• Airbase: since Paylocity completed its acquisition of Airbase in 2024, Airbase's former standalone pricing page now redirects into Paylocity's general pricing hub, and no Airbase-specific price is published; it remains a quote-only sale.
• Plooto: its pricing page lists Go, Grow and Pro at $9, $32 and $99 a month without a currency label next to the figures, and the company bills through both USD and CAD accounts. Without a confirmed USD price on the page, it's left out of the ranked table rather than assumed.

Methodology

Prices for the 4 ranked vendors were read on each vendor's own pricing or fee-schedule page on the day this article was written, in September 2026, in US dollars. The scenario is 200 vendor bills a month, 40 of them (20%) paid to suppliers abroad, with 3 approvers, billed monthly; "Cost at scenario" is the subscription for 3 users plus the per-payment fees for 160 domestic and 40 international bills at each vendor's published rate. Tipalti, Stampli, AvidXchange and Airbase publish no total price for this scenario (Tipalti names a starting price but not its per-transaction fees) and are excluded as quote-only. Plooto is excluded because its pricing page doesn't confirm the currency of its listed figures. QuickBooks Online is excluded because its Bill Pay feature does not support international vendor payments, so it cannot clear this scenario's requirements on its own. The ranking above is ordered only by cost at the stated scenario.

FAQ

What is the cheapest AP automation tool for 200 bills a month in 2026?

Ramp, at $894.40 a month ($10,732.80 a year) for 3 approvers with 20% of bills paid internationally, confirmed on Ramp's pricing and fee pages in September 2026. Its AP plan itself is free; the cost comes entirely from per-payment fees.

Is there a free AP automation tool?

Ramp's Free plan and Melio's Go plan both cost $0 a month, but neither is free at this scenario's volume. Ramp's Free plan has no published bill-volume cap but still charges per-transaction fees on every domestic and international payment (see the pricing table above). Melio's Go plan caps out at 1 user and 5 free ACH payments a month, well short of 200 bills and 3 approvers.

How much does BILL cost for 200 bills a month?

$1,041 a month ($12,492 a year) on the Essentials plan at $49 per user for 3 approvers, plus $0.59 per domestic ACH payment and $19.99 per international USD wire, confirmed on BILL's pricing page in September 2026.

Why aren't Tipalti, Stampli and AvidXchange in the ranked table?

None of the three publishes a full price for this scenario. Tipalti's pricing page lists Accounts Payable "starting at $99/month" but sends the per-transaction fees to a custom quote, Stampli is request-a-quote only, and AvidXchange has no pricing page anywhere on its site. A vendor's true cost at 200 bills a month can't be verified against a number nobody publishes, so all three are excluded rather than ranked on a guess.

Can QuickBooks Online handle this AP scenario?

Not on its own. QuickBooks Online's Bill Pay feature does not support sending payments to international vendors, so it cannot cover the 20% of this scenario's bills going abroad without adding a separate international-payment tool alongside it.

Does Melio charge per approver?

Yes. Melio's Core plan is $25 a month for the first user, and every additional approver costs $10 a month on top, so 3 approvers run $45 a month before any transaction fees, confirmed on Melio's pricing page.

What does Routable cost, and why is it more expensive here?

$1,250 a month flat on the Growth plan, regardless of bill volume or approver count, confirmed on Routable's pricing page. At 200 bills a month it's the priciest of the 4 ranked tools, but its flat rate means it gets relatively cheaper as bill volume climbs past roughly 280 bills a month, where the per-transaction vendors start costing more.

Is Ramp really free for international payments?

No. Ramp markets "free wires" through Bill Pay, but its own fee schedule, in effect since June 2026, charges $20 per international SWIFT USD wire unless the payment is funded from a Ramp Checking Account rather than an external bank account.
