Melio vs BILL for AP: which bill-pay stack fits the job?

The job, not the brand

You need vendors paid on time, fewer “did you get that invoice?” emails, and a clean handoff into QuickBooks Online or Xero. You do not need a platform brochure.

Two products dominate that search: Melio (simple B2B bill pay with a low-friction entry path) and BILL (AP automation with stronger approvals, audit trail, and ERP breadth). They overlap on ACH and check. They diverge on who owns approvals, how many seats you pay for, and how much capture/routing you actually use.

This page is a buy-intent comparison for operators who will pay or switch this month. Dollars and minutes matter more than feature checklists. Focus on the AP job, fees, and fit for your volume.

If you only need to push one invoice through ACH today, open Melio’s entry path and time it. If you already have three people arguing in Slack about who approved a $12k contractor, short-list BILL before you buy another “simple” tool.

Pros and cons (honest)

Melio — strengths / gaps

• + Low friction; free/cheap ACH path for many small shops.
• + Card-to-vendor is a real cash-flow lever when rewards/float beat the fee.
• + Faster first pay run than a full AP platform for solo owners.
• − Thinner approval / ERP story as you scale.
• − Not trying to be full financial ops (spend cards, heavy AR, compliance packs).
• − Teams often outgrow basic workflows around the first finance hire.

BILL — strengths / gaps

• + Approvals, audit trail, ERP breadth.
• + Scales past “owner pays the bills.”
• + Stronger central inbox / capture story at volume.
• − Higher seat cost; overkill for solo operators with five vendors.
• − Longer setup than Melio for a simple Friday pay run.
• − Easy to over-buy seats “just in case.”

Wrong buys

Trial / first steps (20–40 minutes)

Path A — Melio first (owner-approver)

1. Open https://melio.com/pricing and confirm current free/paid structure.
2. Connect the bank account you actually pay from (not a dormant one).
3. Import or upload one real vendor invoice under $500.
4. Time ACH vs card-to-vendor on the same bill if you use cards for float — write the fee and the minutes.
5. Confirm the QBO or Xero sync posts the way your bookkeeper expects (attachment, vendor name, amount).
6. Write a three-line SOP: inbox → approve → pay → sync before close.

Path B — BILL first (multi-approver)

1. Open https://www.bill.com/ and confirm seat model for AP users who must approve.
2. Map roles: submitter, approver 1, approver 2, payer (they are not always the same person).
3. Configure a >$X dual-approval rule that matches your policy, not a demo default.
4. Run one low-risk invoice through capture → approve → pay.
5. Export or inspect the audit trail: who touched what, when.
6. Only then invite the whole team — seats multiply.

Graduation signal (Melio → BILL)

Many shops start Melio and move when: a second full-time finance person arrives; auditors ask for multi-step trails; or sync needs leave QBO/Xero for Intacct/NetSuite-class depth. Graduation is a project, not a weekend toggle — budget parallel pay runs carefully.

Desk Teams context (optional secondary)

If your AP rail is BILL and you want a Grok Bot roster (standing prompts, weekday routines, ~48-hour playbook) on your Cursor / SuperGrok / Teams seats, Desk Teams sells an AP for BILL pack. Pack price: $149 (confirm at https://deskteams.ai).
Buyer-owned AI seat prices (Cursor Ultra / SuperGrok Heavy / Teams Premium): confirm on https://cursor.com/pricing and https://x.ai/grok.

FAQ

Is Melio “free forever”?
There is a marketed free/entry path with limits; paid tiers exist. Confirm ACH caps and card fees on https://melio.com/pricing before you promise “free” to a partner.

Does BILL replace my accountant?
No. It structures payables. Judgment, tax treatment, and close still sit with humans (and your CPA).

Can I pay international vendors?
Both market international options with different rails and fees. Confirm currency, timing, and fee lines on the vendor site for your corridor — treat corridor fee details as confirm-on-vendor before you rely on them.
