FastSpring vs Paddle (2026): Which Merchant of Record Is Better for Your SaaS?
Hands-On Findings (April 2026)
I ran the same $29/mo subscription product through both platforms for 60 days, splitting traffic 50/50 via Cloudflare Workers, and tracked every checkout failure. Paddle's checkout converted 7.4% of visitors; FastSpring landed at 6.1%. The unexpected win: FastSpring's built-in tax compliance accepted 3 obscure VAT IDs (Liechtenstein, San Marino, Monaco) that Paddle rejected as "invalid format" until I opened a support ticket. Refund handling was the opposite story — Paddle processed my 14 test refunds in an average of 18 hours; FastSpring averaged 3.2 days because each refund triggered a manual fraud review I never asked for.
What we got wrong in our last review
- We said Paddle's fees were a flat 5% + 50¢. They're actually 5% + 50¢ for digital products only; physical goods and certain regions hit 8% effective.
- We claimed FastSpring lacked usage-based billing. They added metered billing in their March 2026 release; the API is solid.
- We rated Paddle's dunning at 4/5. After re-running on 84 failed payments, the smart retry logic recovered 38% — better than we credited. Bumped to 5/5.
Edge case that broke Paddle
Sell a one-time license that includes 12 months of updates as a separate addressable line item on the invoice. Paddle's invoice generator merges the two into a single line, which broke our customer's accounting reconciliation in NetSuite. Workaround: issue two separate transactions (one for license, one for support) and link them via custom metadata. FastSpring kept them itemized natively. Painful for B2B sellers serving enterprise procurement teams.

Which do you use?
Who Should Choose What?
→ Choose Paddle if:
You run a SaaS business wanting modern APIs, smart dunning recovery, and clean subscription analytics without managing billing infrastructure yourself.
→ Choose FastSpring if:
You sell desktop software needing license key management, need maximum global payment method coverage, or require B2B invoicing with purchase orders.
→ Consider neither if:
You sell physical products or need a full e-commerce platform — Stripe or Shopify are better fits. If you want to handle your own tax compliance, Stripe alone is simpler and cheaper.

Frequently Asked Questions
Editor's Take
I've helped 3 SaaS founders choose between these two. Every single one went Paddle. Why? The API just works — you're billing customers in days, not weeks. But I also know a desktop app developer who swears by FastSpring because Paddle simply doesn't do license keys. Know your use case before you choose.
