SaaS Payment Provider Landscape 2026: Processors, Merchants of Record, and Subscription Layers

The SaaS payment provider landscape in 2026 divides into three structural categories based on who is the legal seller in the transaction. ## Category 1: Payment Processors **You are the legal seller.** The processor handles money movement; you handle tax registration, collection, and remittance yourself. Major players: Stripe (dominant for developers, ~2.9% + $0.30 per transaction), Braintree (PayPal-owned, strong in enterprise), Adyen (European origin, strong in multi-currency), Mollie (European-focused, simpler than Stripe), Square (strong in physical + digital hybrid). The key burden: if you sell to customers in the EU, UK, and other jurisdictions with sales tax thresholds, you must register for VAT/GST in each jurisdiction, collect the correct tax rate, and file returns — often quarterly. This becomes a significant operational cost at scale. ## Category 2: Merchants of Record (MoR) **A third party is the legal seller.** The customer is buying from the MoR, not from you. The MoR handles global tax registration, collection, remittance, refunds, and chargebacks. You receive net revenue minus their fee. Major players: Polar.sh (developer-focused, 4% + $0.40), Paddle (established, strong in SaaS), Lemon Squeezy (acquired by Stripe in July 2024), FastSpring (enterprise-focused), Dodo, Creem, Gumroad (creator-focused). The trade-off: higher fees (typically 4-5% vs 2.9%) in exchange for eliminating all tax compliance burden. For solo developers and small teams selling internationally, this is often the correct choice. ## Category 3: Subscription Management Layers Sit on top of a payment processor and handle billing logic: dunning (failed payment recovery), plan management, proration, usage-based billing, revenue recognition. Major players: Chargebee, Recurly. These do not replace a processor — they add billing intelligence on top. ## The 2026 Shift: Stripe as MoR Stripe Managed Payments, in private beta since April 2025, positions Stripe as a Merchant of Record — handling tax compliance on behalf of the seller. Built on the Lemon Squeezy acquisition (July 2024). If Stripe launches this publicly in 2026, it could significantly reshape the MoR market by offering MoR services from a processor that most developers already use.
