Running a SaaS or subscription business means recurring billing, dunning, and global payments need to Just Work. We compare Stripe, PayPal, and Wise across developer experience, reach, and cost — plus explain Merchant of Record vs. payment processor so you pick the right stack for your stage.
If you run a SaaS or subscription business, your payment processor isn't just a checkout button — it's the engine that handles recurring billing, dunning emails, failed payment retries, and multi-currency settlements. Pick the wrong one and you bleed revenue to churn and FX fees. Pick the right one and it fades into the background, quietly converting.
Here's our take on the three most important payment tools for subscription businesses, how they compare, and when to use each.
Stripe is the default for a reason. Its API-first design, Stripe Billing module, and rich subscription management tooling make it the go-to for SaaS teams that want to build custom checkout flows without fighting the platform.1
You get automated recurring invoices, smart dunning (retry logic on failed payments), metered billing, and a full customer portal out of the box. The developer experience is best-in-class: clean docs, webhooks for everything, and a dashboard that doesn't get in your way.
Best for: teams that want to own the checkout experience and need deep subscription logic.
PayPal isn't as customizable as Stripe, but it brings something Stripe can't replicate: brand recognition and buyer trust.2 For subscription businesses targeting consumers or less tech-savvy audiences, offering PayPal at checkout can meaningfully lift conversion.
PayPal's subscription API handles recurring payments, and its PayPal Checkout button is a familiar, low-friction option. The trade-off is less control over the flow and higher cross-border fees compared to Stripe.
Best for: businesses where customer trust and familiarity matter more than customization.
If your SaaS sells globally, Wise (formerly TransferWise) isn't a full payment processor — it's a smarter way to handle multi-currency payouts and reduce FX fees. Use it alongside Stripe or PayPal to convert and withdraw funds at the mid-market rate instead of eating 2-3% on every currency conversion.
Wise Business gives you local bank details in multiple currencies, so you can receive USD, EUR, GBP, and more without paying for wire transfers. For subscription businesses with a large international customer base, this is the cheapest way to get your money home.
Best for: global SaaS teams that want to minimize FX costs on cross-border revenue.
| Feature | Stripe | PayPal | Wise |
|---|---|---|---|
| Recurring billing | Native (Stripe Billing) | Via subscriptions API | Not a processor |
| Developer experience | Excellent (API-first) | Good (SDKs available) | Good (API for payouts) |
| Global reach | 135+ currencies | 200+ markets | 50+ currencies |
| FX fees | 1-2% above mid-market | 2.5-4% | Mid-market + small fee |
| Best use case | Custom subscription flows | Consumer trust & checkout | Multi-currency payouts |
One distinction that matters for subscription businesses: Merchant of Record (MoR) vs. payment processor.
A payment processor (like Stripe or PayPal) moves money from the customer to you. You're the merchant — you handle refunds, chargebacks, tax compliance, and PCI compliance.
A Merchant of Record (like Stripe's Tax or services like Paddle) takes on liability for compliance, tax remittance, and fraud. The customer pays the MoR, and the MoR pays you. This is valuable if you don't want to handle VAT/GST in 50+ jurisdictions yourself.
For early-stage SaaS, a processor is fine. As you scale internationally, consider adding an MoR layer or using Stripe Tax to automate compliance.
