How to choose: the tax question decides it
The choice between Paddle and Stripe almost always comes down to who owns your tax liability. With Paddle, the Merchant of Record model means Paddle is the legal seller — it registers for VAT across the EU, collects US sales tax in the states where you have nexus, and remits everything on your behalf. With Stripe, you are the seller of record, so EU VAT registration, the IOSS scheme, and US economic-nexus tracking are yours to handle, usually through Stripe Tax or a tool like TaxJar. Ask one question: do you have the time or accountant to manage filings in multiple jurisdictions? If no, Paddle's higher fee buys back that work. If you already have tax infrastructure or sell primarily in one country, Stripe's flexibility and lower fees win.
