Updated May 2026
What you gain
- ✓No 5% + $0.50 per-transaction fee (Paddle's cut is steep)
- ✓Full control over your billing and invoicing logic
- ✓Direct customer relationships instead of Paddle as merchant of record
- ✓No dependency on Paddle's tax calculation for compliance
What you give up
- △No merchant-of-record service handling global sales tax and VAT
- △No Paddle Retain for automated churn reduction and dunning
- △No built-in license key management for desktop software
- △No managed checkout handling 200+ countries' payment methods
Switching Cost
Paddle's lock-in is the merchant-of-record model. They're the legal seller, which means your customer billing relationships live with Paddle. Switching means you become the merchant of record and take on sales tax, VAT, and compliance responsibilities yourself. Solo devs selling a simple product can move in a week if they use another MoR. SaaS companies with complex subscription plans should budget 3-4 weeks. The hidden cost is massive: global tax compliance. Paddle handled sales tax in 200+ jurisdictions for you, and now that's your problem.

The bulk of what Paddle sells is being your merchant of record, which means they file your taxes, handle VAT/GST in every jurisdiction you sell into, and own the chargeback risk. No OSS replaces that. Kill Bill covers the subscription and invoicing logic; you would still need Paddle or a competitor for the regulated tax-and-compliance piece. If you sell only in one country and can handle your own VAT filings, the OSS stack is enough.
OSS covers
- ✓subscription billing
- ✓invoicing
- ✓metering
OSS does not cover
- △merchant of record
- △global tax compliance
- △VAT/GST collection and remittance
- △chargeback handling
Building Blocks
Paddle is a platform. It bundles multiple capabilities into one subscription. These tools each cover one piece. Teams often assemble 2–3 of them instead of paying for the full suite.
