Best alternatives to JustPaid in 2026
Getting paid on time is one of the most tedious parts of running a B2B company — someone has to read the signed contract, figure out what to bill, send the invoice, and then politely (or not so politely) nag anyone who's late. JustPaid automates that entire chain: it reads a signed contract to pull out the billing terms, generates and sends the invoice, follows up automatically when payment is late, and then checks off the payment against the company's bank account and accounting software once it lands — like hiring a very persistent, very organized billing clerk who never forgets a follow-up. JustPaid supports subscription, usage-based, and hybrid billing models with multi-currency support, and reconciles payments automatically across Stripe, bank feeds, and QuickBooks. The AI-driven collections sequences report an 87% collection rate. It's Y Combinator-backed (W23), SOC 2/GDPR/HIPAA compliant, and integrates with QuickBooks, Xero, Salesforce and NetSuite, having processed over $81M in payment volume across 17,000+ invoices for 9,000+ customers.
