Ramp vs BILL vs Brex for AP automation: AI coding, fees and US pricing
Ramp, BILL and Brex all read incoming vendor invoices with AI, route them through approval rules and pay them by ACH, check, wire or card, yet their published US prices follow three different models. Ramp lists a Free plan at $0 per user per month and a Plus plan at $15 per user per month plus an unpublished platform fee, and from June 1, 2026 it charges $0.59 per standard ACH bill payment and $1.99 per standard check unless the bill is paid from a Ramp Checking Account. BILL lists its AP and AR plans at $49, $65 and $89 per user per month, with $0.59 per ACH payment and $1.99 per mailed check on top. Brex lists Essentials at $0 and Premium at $12 per user per month, and its support documentation states that Brex does not charge transaction fees for ACH, checks, domestic wires or international wires.
The AI layer also differs by plan. Ramp includes automated invoice extraction (OCR) on Free and reserves auto-coded line items and AI-driven approval recommendations for Plus. BILL places its AI multi-line bill coding, the Invoice Coding Agent, in Team, Corporate and Enterprise, while Essentials relies on manual CSV import and export with QuickBooks Online and Xero. Brex shows automatic invoice entry on all three plans and tells users in its documentation that AI pre-filled fields can be wrong and must be checked. For a team paying 124 bills a month with three AP users, the published fees in the worked example below range from $0 on Brex Essentials to $373.76 a month on BILL Team, before any unpublished platform fee or negotiated price.
All prices, fees and features below were read on the vendors' own pricing pages, product pages and help centers on November 10, 2026. Enterprise tiers on all three platforms are quoted on request and are left out of the cost comparison.

AP AUTOMATION WITH AI: WHAT RAMP, BILL AND BREX AUTOMATE.
Accounts payable automation covers the path from an invoice arriving in an inbox to a payment leaving the bank account and a coded bill appearing in the general ledger. The manual version of that path involves keying vendor, invoice number, dates, amounts and GL coding, chasing approvers, scheduling payments and reconciling the payment back to the ERP. Each of the three vendors now applies AI to the first two steps, extraction and coding, and adds rule-based or AI-assisted checks before money moves. The control questions that come with this work, such as cut-off, duplicate payments and the aging of unpaid bills, do not disappear; our explainer on accounts payable aging and supplier payments covers the reporting side that sits downstream of these tools.
Ramp describes its Bill Pay product as built around four specialized AI agents covering auto-coding, fraud prevention, approvals and automatic payments. Its product page states that the OCR captures each detail and line item with 99% accuracy, that the coding agent learns from past invoices and applies the same logic to new ones, and that two-way and three-way matching checks every line item against purchase orders. The fraud agent flags suspicious activity such as unexpected changes to vendor banking details before payment.
BILL states on its AI product page that its AI extracts key fields and codes multi-line bills, predicting account, amount, department, class, location, customer and job from previous bill entries. BILL gives an extraction figure of approximately 99% accuracy under tested conditions and qualifies it in a footnote as based on the top 20% of common bills, with results varying by layout and data quality. Users review, edit or undo the suggestions before finalizing the bill, admins can switch AI capabilities on or off, and an audit log records AI actions. BILL also lists duplicate bill detection, which compares new bills with existing ones using vendor, invoice number, due date, amount and document data, and a W-9 agent that requests and validates vendor tax forms.
Brex converts an uploaded or emailed invoice into a draft bill. Invoices can be forwarded to a unique Brex address or to bills@brex.com from a registered user email, in PNG, PDF, JPEG, JPG, TXT or DOCX format, and the documentation recommends one invoice per email, written in English and in USD. AI pre-fills the bill fields, and the help center states that it is the user's responsibility to make sure the fields are filled out correctly. Bills are then routed by the Policy Engine according to amount and vendor.

RAMP, BILL AND BREX US PRICING AND PLAN LIMITS.
The three pricing pages use different units, so the comparison below keeps each vendor's own wording. Ramp's page also states that annual billing saves 20% on Plus, but the platform fee that Plus adds is based on team size and is not published. BILL's page does not say whether its per-user prices assume monthly or annual billing.
........
Plan | Listed price | AI on AP | ERP sync |
Ramp Free | $0/user/month | Invoice extraction (OCR) | QuickBooks Online, Xero |
Ramp Plus | $15/user/month + platform fee | Auto-coded lines, AI approval suggestions | Adds NetSuite, Sage Intacct |
BILL Essentials | $49/user/month | No coding agent | Manual CSV (QBO, Xero) |
BILL Team | $65/user/month | Invoice Coding Agent | 2-way sync QBO, Xero |
BILL Corporate | $89/user/month | Invoice Coding Agent | 2-way sync QBO, Xero |
Brex Essentials | $0/user/month | Automatic invoice entry | Includes NetSuite |
Brex Premium | $12/user/month | Automatic invoice entry | Custom ERP and HRIS |
........
Approval depth follows the same pattern. Ramp Free lists configurable approval workflows, and Plus adds routing by vendor, department, accounting field and payment type, automated batch payments and payment release approvals. BILL includes approval workflows on every plan and custom approval policies from Corporate upward, where two-way matching for procurement is also included rather than sold as an add-on. Brex lists multi-level approval flows on Essentials and adds advanced approvals with dynamic spend-limit approval chains on Premium; its documentation adds that spend limits are required by default on Essentials and optional on Premium and Enterprise.
For integrations, Ramp moves NetSuite and Sage Intacct to Plus and Workday and Oracle Fusion Cloud to Enterprise. BILL keeps NetSuite, Sage Intacct, Microsoft Dynamics, QuickBooks Enterprise, Acumatica and Rillet for Enterprise. Brex's support page lists bill sync with QuickBooks Online, NetSuite, Sage Intacct and Xero, with virtual card payment records syncing to the ERP for NetSuite only.

BILL PAYMENT FEES: ACH, CHECK, WIRE AND INTERNATIONAL.
Payment fees decide much of the real monthly cost for a company that pays many small vendors. Ramp's help center lists the following Bill Pay fees, with the standard ACH and check fees taking effect on June 1, 2026 and a three-month grace period for active customers who paid at least one bill before May 1, 2026. Paying from a Ramp Checking Account waives the standard ACH, standard check, same-day ACH, domestic wire and SWIFT fees, while overnight check delivery and check attachments are still charged. Batched payments to the same vendor in one ACH or check incur one fee.
........
Payment type | Ramp | BILL | Brex |
Standard ACH | $0.59 | $0.59 | No fee |
Same-day ACH | $10 | $11.99 | Not stated |
Standard check | $1.99 | $1.99 | No fee |
Domestic wire | $15 | Not listed | No fee |
International USD wire | $20 | $19.99 | No fee |
International FX wire | Not stated | Free, FX rate applies | No fee, Brex FX rate |
Overnight check | $20 | $24.99 | Not stated |
........
BILL also lists instant payment at 1.0% with a $9.99 minimum and a $100 maximum, free virtual card payments, and a 2.9% charge when the payer funds a payment by credit or debit card. Brex warns that third-party banks may still charge fees and that foreign currency wires use the exchange rate chosen by Brex, locked once the bill is approved and ready to be paid. Brex does not support international checks or international ACH, even in USD. Ramp's pricing page adds $0.65 per IRS 1099 filing with free state filing on all plans.

WORKED EXAMPLE: MONTHLY AP COST FOR 124 BILLS.
The example below is illustrative. A US company has three AP users and pays 124 bills a month: 100 by standard ACH, 20 by mailed check and 4 by international wire in USD. It pays from an external bank account, so Ramp's checking-account waiver does not apply. Only published list prices are used; Ramp's Plus platform fee is not published and is excluded, and bank fees charged by third parties are left out.
........
Cost line (monthly) | Ramp Free | BILL Team | Brex Essentials |
Subscriptions (3 users) | $0.00 | $195.00 | $0.00 |
100 ACH payments | $59.00 | $59.00 | $0.00 |
20 checks | $39.80 | $39.80 | $0.00 |
4 international USD wires | $80.00 | $79.96 | $0.00 |
Total per month | $178.80 | $373.76 | $0.00 |
Total per year | $2,145.60 | $4,485.12 | $0.00 |
........
The same volume on BILL Essentials costs $325.76 a month ($147 in subscriptions plus $178.76 in fees), and on BILL Corporate $445.76. Ramp Plus would cost $223.80 a month before the platform fee ($45 in subscriptions plus $178.80 in fees), or $45 plus the platform fee if the bills were paid from a Ramp Checking Account. Brex Premium would cost $36 a month for three users. The cheapest line in the table is also the one with the least documented AI coding, which makes the AI features the deciding variable once fees are known.
A finance team can rebuild the comparison in Excel with its own volumes. With the inputs in named cells, the monthly cost of one plan is a single formula, and the sheet can be extended with same-day ACH or overnight check counts.
=Users*PricePerUser + ACH_Count*ACH_Fee + Check_Count*Check_Fee + Wire_Count*Wire_Fee
BILL Team example: =3*65 + 100*0.59 + 20*1.99 + 4*19.99 returns 373.76Asking Copilot in Excel, Claude or ChatGPT to build this sheet from a pasted fee table is a reasonable shortcut, as long as the result is checked against the figures above. A model that applies Ramp's $15 domestic wire fee to international wires, or forgets that BILL charges per user, will produce totals that look plausible and are wrong.

HOW TO CHECK AI-CAPTURED INVOICES BEFORE APPROVAL.
Vendor accuracy figures describe extraction under tested conditions, and BILL's own footnote limits its figure to the most common bill layouts. The practical control is to confirm that the extracted lines add up to the extracted header before a bill reaches an approver. In an illustrative invoice with 40 units at $18.50, 12 units at $62.00 and one service fee of $350.00, the line amounts are $740.00, $744.00 and $350.00, the subtotal is $1,834.00, sales tax at 7.25% is $132.97 and the invoice total is $1,966.97. If the captured bill shows a total that differs from the sum of its captured lines plus tax, either a line was missed or a quantity was misread.
........
Check | What to compare | Typical AI error |
Line arithmetic | Quantity x price vs line amount | Misread quantity or decimal |
Header total | Lines + tax vs invoice total | Missed line on page two |
Vendor bank details | Captured vs vendor master | Changed account (fraud) |
Duplicate | Vendor + invoice number + amount | Same bill emailed twice |
GL coding | Suggested account vs policy | Coding copied from an old bill |
........
Coding agents that learn from past bills reproduce past mistakes as reliably as past good decisions, so a sample review of AI-coded lines each close is a sensible control, especially after chart-of-accounts changes. Changes to vendor bank details should stay human-verified through a call-back to a known contact, whatever the fraud agent flags. Payment release should remain with a person who did not draft the bill; Brex's documentation notes that when the drafter is also the first approver, the approval toggle defaults to on and auto-approves the bill, a setting to review during implementation. BILL's admin switch and AI audit log give reviewers a record of what the AI changed. Teams comparing receipt and expense capture rather than vendor invoices can read our Dext vs Hubdoc vs QuickBooks receipt capture comparison, and those still choosing a general ledger can start with QuickBooks Online vs Xero plan limits and pricing.

CHOOSING BETWEEN RAMP, BILL AND BREX FOR AP AUTOMATION.
On published list prices, Brex is the only one of the three that charges neither a per-user fee on its entry plan nor transaction fees on ACH, checks and wires, and it includes AI invoice entry and NetSuite sync on Essentials. Ramp Free matches the zero subscription and adds OCR extraction, and its payment fees fall to zero for standard ACH, checks and wires when bills are paid from a Ramp Checking Account; its line-item auto-coding and AI approval recommendations sit on Plus, whose platform fee is not published. BILL is the most expensive per user, and the Invoice Coding Agent with two-way QuickBooks Online and Xero sync starts at $65 per user per month on Team, but it documents the most detail about how its AI predicts coding fields, how users undo suggestions and how admins audit AI actions.
Several points cannot be settled from public pages. Ramp's Plus platform fee, BILL's billing period and every Enterprise price require a quote, and Ramp's international FX payment pricing and Brex's same-day ACH terms are not stated on the pages reviewed. The 99% extraction figures from Ramp and BILL are vendor claims, and only BILL describes the conditions behind its figure. A team that already runs its close on a dedicated platform can compare how AP data flows into reconciliation with our BlackLine vs FloQast close comparison. For most US teams the deciding inputs are payment volume by method, whether paying from the vendor's own bank account is acceptable, and which ERP has to receive the coded bills.
