Bill.com Alternatives: 5 Better Options for Modern AP

BILL (formerly Bill.com) is like the reliable old sedan in your garage – widely trusted, gets the job done, but starting to feel its age. It was built in the early 2000s and it shows.

‍

While BILL helped digitize accounts payable for businesses, modern finance teams face increasingly complex challenges beyond what traditional AP systems were designed to handle. Whether it's managing global payments, streamlining procurement workflows, or exploring emerging payment technologies like digital assets, finance leaders are seeking more versatile alternatives. 

‍

This post explores the five best alternatives to BILL: Bitwave, Tipalti, Airbase, Melio, and Coupa Pay. Each has its own strengths, so I’ll break down what they do best, where they fall short, and who they’re really built for.

‍

1. Bitwave

Best for: Crypto-enabled finance teams and enterprises needing dual fiat + digital asset workflows

‍

Bitwave bridges the stability of traditional payments with the speed and efficiency of crypto. It lets you send fiat and crypto payments, reconcile them, and maintain full compliance. Built for finance teams navigating the digital asset economy, Bitwave combines AP/AR automation with its enterprise-grade subledger – with audit-ready accounting and tex reporting and integrations with the wallets, exchanges, and ERPs you use most.

‍

✅ Pros

• Real-time stablecoin and crypto payments
• Dual fiat and crypto workflows
• Digital asset accounting subledger (audit-ready)
• ERP integrations (NetSuite, QuickBooks, etc.)

‍

⚠️ Cons

• Not focused on T&E or procurement workflows
• Overkill for simple fiat-only payment operations

2. Tipalti

Best for: Global AP automation with deep compliance needs

‍

Tipalti is a global payments and payables automation platform. It supports payouts in 190+ countries and handles tax compliance, mass payments, and vendor onboarding.

‍

✅ Pros

• Handles tax forms (W-8/W-9), VAT compliance, OFAC checks
• Supplier portal for self-service updates
• Mass payouts, global currency support

‍

⚠️ Cons

• No stablecoin or crypto support
• UI can be slow or rigid for some workflows
• Vendors must create separate logins per client

3. Airbase

Best for: Unified spend management with AP, cards, and reimbursements

‍

Airbase offers a true all-in-one platform for managing non-payroll spend. It includes AP, corporate cards, expense reimbursements, and guided procurement workflows.

‍

✅ Pros

• All spend types in one system
• Advanced approval workflows and real-time dashboards
• Strong ERP sync and automation

‍

⚠️ Cons

• No stablecoin or crypto support
• Better suited to mid-market firms (100+ employees)
• Can be complex to implement

4. Melio

Best for: Small teams needing a lightweight bill pay tool

‍

Melio simplifies vendor payments for QuickBooks and Xero users. It’s ideal for startups needing to pay by ACH or credit card without a heavy system.

‍

✅ Pros

• Extremely easy to use
• Pay vendors by credit card, even if they only take ACH
• QuickBooks and Xero sync

‍

⚠️ Cons

• Limited workflow control
• No multi-entity or crypto support
• Melio upset some early users by moving previously free features behind a paywall. The free tier now limits you to very basic functionality (e.g., a handful of free ACH transfers).
• Melio’s simplicity is a double-edged sword – great for small needs, but you may outgrow it. You won’t find purchase order matching, budget vs actual reports, or an ERP-level audit trail.

5. Coupa Pay

Best for: Enterprises looking for full procurement-to-pay integration

‍

Coupa Pay is the payments module within Coupa’s spend management suite. It’s designed for large enterprises that need to integrate sourcing, procurement, and payments.

‍

✅ Pros

• Deep integration with Coupa’s procurement workflows
• Strong compliance and audit controls
• Supply chain finance features (e.g. early payment discounts)

‍

⚠️ Cons

• High cost and long implementation time
• Clunky UI for some users
• No crypto support

The Bottom Line

Bill.com paved the way for AP automation, but modern finance leaders are facing new demands: global scalability, real-time settlement, and crypto readiness. 

‍

If your business is outgrowing the limitations of bank rails and legacy AP systems, exploring alternatives like Tipalti, Airbase, Coupa Pay, and especially Bitwave, may be the smartest move you make this year.

‍

Bitwave is particularly compelling for companies operating in both fiat and crypto—offering the compliance infrastructure your auditors require, and the speed your global vendors demand.
