Bill.com vs Melio: Which AP and Payment Platform Is Better?

TL;DR: Melio is the better choice for small businesses that want free bill payments and simple AP management. Bill.com (now BILL) suits mid-size businesses needing approval workflows, accounts receivable, international payments, and enterprise-grade AP automation. You pay more with BILL but get significantly more automation.

Quick comparison

Invoice creation and accounts receivable

BILL offers accounts receivable features — create and send invoices, accept payments, and track outstanding balances. This makes it a two-sided platform handling both what you owe and what you are owed. Melio focuses exclusively on accounts payable — paying your bills, not sending invoices to clients.

If you need an invoicing tool alongside your AP platform, BILL includes it. With Melio, you will need a separate invoicing solution. Tools like InvoiceQuickly pair well with Melio for businesses that need simple invoicing alongside their bill payment workflow.

Pricing

Melio is free for bank transfers (ACH) and charges 2.9% for card payments. This makes it accessible for small businesses paying a handful of vendors. BILL Essentials is $45/user/month, Team is $55/user/month, and Corporate is $79/user/month. Enterprise pricing is custom.

The cost difference is substantial. A three-person team on BILL pays $135-$237/month before payment processing fees. The same team on Melio pays nothing for ACH payments. BILL justifies its cost through advanced automation, approval workflows, and breadth of features.

Automation and workflows

BILL's automation is its core strength. AI-powered invoice capture reads and extracts data from uploaded bills (OCR). Multi-step approval workflows route bills to the right approvers based on amount, vendor, or department. Scheduled payments, automatic two-way sync with accounting software, and audit trails make it a serious AP platform.

Melio automates the basics — schedule payments, sync with QuickBooks or Xero, and set up recurring payments. Approvals are available but limited compared to BILL's multi-level workflow engine. For businesses processing fewer than 50 bills per month, Melio's automation is usually sufficient. For finance teams processing hundreds of bills with multiple approvers, BILL's workflow engine eliminates bottlenecks that Melio cannot address.

Integrations

BILL integrates with QuickBooks, Xero, Sage, NetSuite, and Oracle — covering small to enterprise accounting platforms. The two-way sync ensures bills and payments flow automatically between systems. Melio integrates with QuickBooks and Xero, covering the two most popular small business accounting platforms.

For businesses on Sage, NetSuite, or other mid-market platforms, BILL is often the only viable option.

Ease of use

Melio is simpler to set up and use. Upload a bill (or enter details manually), schedule a payment, done. The interface is clean and focused. BILL has more to configure — approval workflows, user permissions, payment policies — but this complexity reflects its more powerful feature set.

Small businesses that want to pay bills without a learning curve prefer Melio. Finance teams that need controls and compliance prefer BILL. If you also need an invoicing tool for sending invoices to your own clients, remember that BILL includes accounts receivable while Melio does not — you will need a separate invoicing platform alongside Melio.

Customer support

BILL offers phone, email, and chat support with dedicated account management on higher plans. Melio provides email and chat support with helpful onboarding assistance. BILL's support infrastructure is more robust, which matters for businesses processing critical vendor payments. Melio's support is adequate for its simpler feature set and smaller business audience.

Verdict

Choose Melio if you are a small business that wants to pay vendors via ACH for free, needs basic bill management, and does not require complex approval workflows. The free tier is genuinely useful.

Choose BILL if you process high bill volumes, need multi-level approvals, want AR and AP in one platform, or operate at a scale where AP automation saves significant staff time. The cost is high but the automation ROI is real for mid-size businesses.

Frequently asked questions

Can I pay vendors by credit card through either platform?

Yes. Both let you pay vendors by credit card even when the vendor only accepts checks or ACH — the platform converts the payment. This earns you card rewards on bill payments. Both charge approximately 2.9% for card payments. Factor in your rewards rate to determine if the fee is worth it.

Which is better for accounts payable automation?

BILL by a wide margin. OCR invoice capture, multi-level approval routing, custom policies, and enterprise integrations make it purpose-built for AP automation. Melio is a bill payment tool with light AP features, not an AP automation platform.

Can Melio handle international payments?

Melio has limited international payment support. BILL offers international wire transfers in multiple currencies with better exchange rates and compliance features. For businesses that regularly pay international vendors, BILL is the stronger choice.

How do they handle duplicate payments?

BILL has built-in duplicate payment detection that flags potential double payments before they process. Melio relies on you to catch duplicates manually. For businesses processing dozens or hundreds of bills monthly, BILL's safeguards prevent costly errors that are surprisingly common in manual AP workflows.
