1. Paddle
Usage-basedEstablished merchant of record
Paddle is a mature merchant-of-record built for SaaS, taking on global tax, compliance, billing, and fraud so you don't have to register for VAT anywhere. Its enterprise-grade billing and reporting are a strength. The trade-off is that onboarding approval can be stricter and its interface less indie-friendly than newer, lighter tools.
Best for: Established SaaS wanting hands-off tax
