In 2026, Stripe remains the developer darling, Paddle solves the tax compliance headache as a Merchant of Record, and Lemon Squeezy targets indie makers with a simpler experience.

Merchant of Record (MoR) Explained

With Stripe, you are the merchant — you handle tax collection, remittance, and compliance. Stripe Tax helps calculate tax but you still file returns. With Paddle and Lemon Squeezy (MoRs), they are the merchant — they handle all tax liability, file returns in every country, and deal with compliance. You receive a single payout. The tradeoff: ~2% higher fees for zero tax headaches.

When Each Processor Wins

Stripe — Best for: US/EU-based businesses with simple tax situations, or businesses that can afford an accountant for global compliance. Stripe's API quality, documentation, and ecosystem are unmatched. Weak spot: Global tax compliance is on you — at $20K+/month in global revenue, tax filing complexity becomes a real operational burden.

Paddle — Best for: Global SaaS businesses that want to sell worldwide without worrying about VAT, GST, or sales tax registration in dozens of countries. Paddle's MoR model means you never deal with tax authorities — they handle everything. Weak spot: Higher fees (5% + $0.50 vs Stripe's 2.9% + $0.30); approval process (requires business verification); less flexible API than Stripe.

Lemon Squeezy — Best for: Indie developers and small SaaS products that want a simple, fast setup with built-in features like affiliate tracking, email marketing, and license key delivery. Weak spot: Newer platform (less battle-tested); fewer integrations; API is simpler but less powerful.

Fee Comparison at Different Revenue Levels

Monthly RevenueStripe (2.9% + $0.30)Paddle/Lemon Squeezy (5% + $0.50)Difference
$1,000 (50 transactions)$44$75$31 more for MoR
$10,000 (200 transactions)$350$600$250 more for MoR

$100,000 (1,000 transactions)$3,200$5,500$2,300 more for MoR

Bottom line: Start with Stripe if you are in one country with simple tax. Switch to Paddle (or add it alongside Stripe) when global tax compliance becomes painful — typically around $5K-10K/month in international revenue. The ~2% MoR premium is cheaper than hiring an international tax accountant. Lemon Squeezy is the best all-in-one for indie makers who want simplicity over flexibility.
