How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- Melio and Ramp suit small teams that want low starting costs, while Tipalti and Stampli suit larger, global, or high-volume AP work.
- Brex and Mercury bundle bill pay with cards and banking, which can replace several tools at once for startups.
- Quote-based tools such as Stampli and AvidXchange need a sales conversation, so budget extra time for demos and implementation.
- Payment fees, approval depth, and accounting sync matter more than the headline subscription price alone.

#1Melio
Best for: Small-business bill pay4.4/5 on
G2 (248 reviews, checked Oct 2026)
Visit melio.com
Starting priceSee website
Free planYes
Melio suits a small business that wants to stop paying bills by hand without a long implementation. Upload or forward an invoice, approve it, and pay by bank transfer, card, or check through Melio, even when the vendor only accepts paper checks. That check-handling trick removes a common reason small teams keep manual processes.
The limits appear as volume grows. The free tier covers only a small number of users and payments, and card payments carry a percentage fee that adds up if used for large bills. International coverage is narrower than Tipalti. For US small businesses paying a modest vendor list, Melio is an easy first alternative to BILL.
What we like- Simple bill pay setup
- Pay vendors by card even if they accept checks
- QuickBooks and Xero sync
Watch out for- Advanced approvals sit on higher tiers
- International payments are limited
- Card fees add up
#2Ramp
Best for: Free AP plus cards4.8/5 on

Visit ramp.com
Starting price$0
Free planYes
Ramp combines bill pay, corporate cards, and expense management in one free starting tier, which is why it appears in so many BILL comparisons. Invoices are captured with AI, coded, routed for approval, and paid, while cards give teams spend controls in the same system. For startups and small businesses that already want cards, the bundle is hard to ignore.
Paid tiers add deeper approvals, purchase order matching, and ERP sync for NetSuite and Sage Intacct. Teams that only need AP, without cards, may find parts of Ramp less relevant, though the free bill pay still stands on its own. If your team wants AP and spend controls together at no software cost to start, Ramp is the pick to trial first.
What we like- Free bill pay tier
- Corporate cards included
- AI invoice capture and approvals
Watch out for- Advanced AP controls need Ramp Plus
- NetSuite and Intacct sync on paid tiers
- Card-led model suits some teams less
#3Brex
Best for: Cards, banking, and AP together4.8/5 on
G2 (1,643 reviews, checked Oct 2026)
Visit brex.com
Starting price$0
Free planYes
Brex started as a corporate card company and has grown into a finance platform with bill pay, banking, expenses, and travel. Its free Essentials tier covers cards, basic bill pay, and approvals, while Premium adds live budgets, multi-entity support, and deeper controls. Global payments and wires suit startups with international vendors or contractors.
The main watch point is eligibility and tier fit. Brex underwriting and account requirements differ from BILL, and some AP features that BILL includes on mid tiers sit on Brex Premium. For venture-backed startups and scaling companies that want one finance stack, Brex is a strong alternative.
What we like- Free Essentials tier
- Multi-level approvals
- Global wires and cards
Watch out for- Premium features cost $12 per user per month
- Underwriting requirements apply
- AP depth varies by tier
#4Tipalti
Best for: Global vendor payments4.5/5 on
G2 (419 reviews, checked Oct 2026)
Visit tipalti.com
Starting price$99 per month
Free planNo
Tipalti suits companies that pay many vendors, suppliers, or creators across borders. It handles supplier onboarding, tax form collection, approvals, and payments in many currencies and methods, with integrations for NetSuite, Sage Intacct, QuickBooks, and Xero. That compliance layer is the reason global teams choose Tipalti over a simple bill pay tool.
Costs go beyond the $99 monthly starting figure, since transaction fees apply and higher tiers add features. Implementation also needs time for supplier data, tax rules, and ERP mapping. For a US-only small business with ten vendors, Tipalti is more than needed. For a company paying globally at volume, it is one of the most complete options here.
What we like- Payments to 200 plus countries
- Tax forms and compliance built in
- Strong ERP integrations
Watch out for- Higher starting price
- Transaction fees on top
- Implementation takes planning
#5Stampli
Best for: Collaborative invoice approvals4.6/5 on

Visit stampli.com
Starting priceSee website
Free planNo
Stampli centers on how approvers actually work: comments, questions, and decisions live on the invoice itself, rather than in separate email threads. Its AI assistant, Billy, suggests coding and routing based on past behavior, which speeds up high-volume AP. It connects with more than 70 accounting and ERP systems, so teams are less likely to need a system change to adopt it.
Pricing is quote-based by invoice volume, with unlimited users on paid plans, so small teams cannot judge cost from a public page. A demo and volume estimate are required, and rollout benefits from training approvers on the new workflow. For midmarket teams where approval bottlenecks are the real problem, Stampli deserves a demo.
What we like- In-invoice collaboration for approvers
- AI coding assistant
- Works with many ERPs
Watch out for- Quote-based pricing
- No free plan
- Implementation and training needed
Starting price$0
Free planYes
Mercury is a business banking platform that also handles bills, which suits startups that want banking, cards, and bill pay in one account. Bills arrive in an inbox, are read with OCR, routed for approval, and paid from the Mercury balance, with accounting sync to QuickBooks, Xero, and NetSuite. That closeness to cash flow helps small teams see what is due and what is available in one view.
Mercury is not a full AP suite for complex procurement or three-way matching, so larger finance teams may outgrow it. Paid tiers add features and higher limits, and banking eligibility rules apply. For startups already considering Mercury for banking, its bill pay is a genuine reason to skip a separate AP tool at first.
What we like- Free business banking starting point
- Bill inbox with OCR
- Approvals on all plans
Watch out for- AP is part of banking, not a standalone AP suite
- Advanced tiers cost more
- No PO matching depth
Starting priceSee website
Free planNo
QuickBooks Bill Pay suits businesses already running QuickBooks Online, since bills, payments, and accounting stay in one system. There is no separate sync to maintain, and the interface is familiar to bookkeepers and accountants who already use QuickBooks daily. For small teams with straightforward approvals, that simplicity outweighs a dedicated AP suite.
The trade-off is depth. Multi-step approvals, purchase order matching, and global payment features are thinner than in Tipalti or Stampli, and pricing depends on the QuickBooks plan and Bill Pay add-on chosen. Teams that outgrow QuickBooks approvals should look at Ramp or Melio as a next step before a full ERP-grade tool.
What we like- Native QuickBooks Online integration
- No second login for accounting
- Familiar interface
Watch out for- AP depth is lighter than dedicated tools
- Pricing sits inside QuickBooks plans
- Advanced approvals limited
Starting priceSee website
Free planNo
AvidXchange targets midmarket companies moving from paper invoices and checks to automated AP. It captures paper and emailed invoices, routes them for approval, and pays suppliers through its network by check, ACH, or virtual card. Integrations with many ERPs and accounting systems help larger teams keep their system of record while changing how invoices arrive and get paid.
Expect a sales-led process with implementation, supplier enrollment, and training, rather than self-serve signup. That effort pays off for companies with high invoice volume and many suppliers, but it is too much for a ten-person business. For paper-heavy midmarket AP, AvidXchange is a proven alternative to BILL.
What we like- Large supplier network
- Paper invoice digitization
- Many ERP integrations
Watch out for- Quote-based pricing
- Implementation project required
- Overkill for small teams
How we chose
We compared tools on AP fit, approval depth, payment methods, global coverage, accounting integrations, and pricing transparency. Prices were taken from vendor pages and recent published comparisons, with quote-based tools marked as See website rather than guessed. We did not claim hands-on testing. Public reviews and vendor documentation were used to check approval, sync, and payment claims.
What to check before switching from BILL
This guide compares software features and prices. It is not financial advice, and payment, tax, and banking rules for your business should be confirmed with your accountant or finance adviser. Start by listing what BILL does for you today, including approval chains, payment methods, and integrations, then match that list against each alternative.
Count the real cost
Add subscription, per-user fees, ACH and check fees, card percentage fees, and any FX or international charges for a typical month. A free tool with high card fees can cost more than a paid tool with free ACH, depending on how you pay. Use last month's invoice count and payment mix, not a vendor example, for the estimate.
Test approvals with real approvers
Approvals fail more often from workflow friction than from missing features. Run a pilot with actual managers, test mobile approval, delegation when someone is away, and audit trails for finance. A tool that approvers avoid will not save time, even if its feature list looks complete.
Confirm the accounting sync
Check whether sync is one-way or two-way, how often it runs, and how errors are shown and fixed. A sync that drops a bill or duplicates a payment creates month-end work that erases automation gains. Ask for a sync error report example during a demo, and test it with your own chart of accounts.
Frequently asked questions
What is the cheapest Bill.com alternative?
Ramp and Brex both start free for core bill pay and cards, and Mercury starts free for banking plus bill pay. Melio also offers a free starting tier for very small volumes. The cheapest overall choice depends on payment fees and whether you need paid approvals or ERP sync.
Can I pay vendors by credit card if they only accept checks?
Yes, Melio and similar tools let you pay by card on your side while the vendor receives a check or bank transfer. Card fees apply, usually as a percentage, so this route suits cash-flow timing or rewards goals rather than every bill. Check the exact fee before using it for large payments.
Which alternative is best for global payments?
Tipalti is the strongest pick here, with payments to 200 plus countries, many currencies, and tax compliance built in. Brex also handles global wires, while Melio and Mercury cover fewer countries. For a large international vendor list, prioritize tax forms and payment method coverage over headline price.
Do these tools sync with QuickBooks and Xero?
Most do, with depth varying by tier. Melio, Ramp, Tipalti, Mercury, and QuickBooks Bill Pay all sync with QuickBooks, and several also sync with Xero. NetSuite and Sage Intacct sync often sits on paid or midmarket tiers, so confirm your exact ERP version before signing.
How long does switching from BILL take?
A small team can switch in days if approvals are simple and vendor data exports cleanly. Midmarket moves with ERP mapping, supplier enrollment, and approval redesign can take weeks. Export vendor lists, open bills, and approval histories before canceling BILL, and run both systems in parallel for one payment cycle if possible.
