Melio vs BILL.com for AP in 2026

Verdict

Pick Melio if you are a US shop that pays a stack of vendors, wants approvals, and will use ACH instead of mailing checks or putting the landlord on a personal card. Pick BILL if your bookkeeper already has a login in that network and you will model seats at $49 / $65 / $89 per user — not the headline. Do not pick Melio as a travel-and-expense suite. Do not pick BILL Essentials for two bills a month.

This is complementary to Is Melio worth it and Best bill pay software for small business. Is Ramp worth it is the card-plus-AP fork. We are not your accountant. ACH is the cheap rail. Card-to-vendor fees fund a lot of “free” software.

Two jobs

Melio’s job is SMB accounts payable: capture the bill, approve it, pay ACH, post something a ledger can take. A free Go-class plan exists. Paid Core / Boost / Unlimited are commonly listed from about $25 / $55 / $80 per month. QBO sync is a known path. Vendors get a link. You do not share the operating login. That is why Melio sits as the Incacent default on the bill-pay ranking.

BILL’s job is an accountant-network AP/AR suite. Many US bookkeepers already live there. Accounts Payable / Receivable publishes Essentials $49/user/month, Team $65, Corporate $89 on bill.com/product/pricing. Spend & Expense software is $0/user (cards require approval). Transaction fees apply. Implementation is a project if you are leaving a shoebox. Five users on Essentials is $245/month before payment fees.

Ramp includes bill pay on a spend platform — Free $0 / Plus $15+platform — if cards and policy are the rest of the job. Relay is banking with payments, not a full AP desk. QBO bill pay or the bank’s bill pay is enough if volume is tiny. Two AP tools is how you double-pay. Appoint one closer of vendor bills.

Public pricing as of September 21, 2026

Melio: free Go-class plan and paid Core / Boost / Unlimited commonly listed from about $25 / $55 / $80 per month. ACH is the cheap way to pay. Paying a vendor by card costs more — that fee is how “free AP” is funded when you choose plastic. Confirm melio.com/pricing.

BILL: AP/AR Essentials $49/user/month; Team $65; Corporate $89. Spend & Expense software $0/user. Transaction fees apply. Confirm bill.com/product/pricing. Approval-only seats exist on higher tiers — ask.

• Ten ACH vendor payments on Melio Go: often $0 software if you stay in the free cap.
• Melio Core at ~$25 if you need the next tier of users/approvals.
• One $5,000 vendor paid by card at a few percent can exceed a year of Melio Core. Prefer ACH.
• Two BILL Essentials users: $98/month before payment fees. Five users: $245.
• Ramp Free includes bill pay if you are already on Ramp. Do not stack Melio on top.

Who should pick which

• Founder plus a bookkeeper, stack of vendors, will use ACH: Melio.
• Bookkeeper already in the BILL network and will not leave: BILL — model seats.
• Cards, receipts, and policy are the leak: Ramp. See Is Ramp worth it.
• Two bills a month from the bank and it works: stay. Do not buy software.
• International vendors as a habit: read both vendors’ rails before you assume ACH is enough.
• You wanted employee cards, not vendor links: Ramp or BILL Spend — not Melio Go.

Skip-ifs

Skip Melio if you already pay bills inside Ramp or QBO and it is fine. Skip BILL if you wanted $0 software and ten ACH payments. Skip both if you will pay every vendor by card “for points” and ignore the fee. Skip buying Corporate to impersonate a controller. AI AP bots stay on Aiacent. Confirm official URLs.
