Stripe vs Other Payment Gateways for a New MVP
Founders often ask which payment gateway to use before they’ve asked what actually differs between them. For most MVPs, the honest answer is that the gateways are more alike than different on raw pricing — the real differences are in integration effort, tax handling, and how well each fits your specific business model.
The Short Version
| Stripe | PayPal | Braintree | Paddle | |
|---|---|---|---|---|
| Standard fee | ~2.9% + $0.30 | ~2.9% + $0.30 (varies) | ~2.9% + $0.30 | Higher (~5%), but includes tax handling |
| Documentation quality | Excellent | Fair | Good | Good |
| Best for | Custom SaaS/marketplace products | Products where buyers already trust/use PayPal | Similar to Stripe, common in mobile-first stacks | International SaaS avoiding manual tax compliance |
| Merchant of record | No — you handle tax compliance | No | No | Yes — Paddle handles sales tax/VAT for you |
For a typical software MVP building a custom checkout or subscription flow, Stripe’s fee is comparable to the alternatives, but its documentation and SDK maturity reduce integration risk — which matters more at MVP stage than a fractional difference in transaction fees.
Where PayPal Still Wins
PayPal’s advantage isn’t documentation — it’s buyer trust and existing account penetration. If your target customers are consumers who already have PayPal accounts and are wary of entering card details on an unfamiliar site, offering PayPal as a payment option alongside a card gateway can reduce checkout abandonment. It’s rarely the only gateway a product needs, but it’s a reasonable addition once the core payment flow is stable.
Where Paddle Changes the Calculation
Paddle’s higher fee buys something specific: it acts as the merchant of record, meaning Paddle — not you — is legally responsible for collecting and remitting sales tax and VAT across the regions you sell into. For a SaaS product selling internationally from day one, this can save meaningful legal and accounting overhead that would otherwise need to be handled separately. For a product selling only domestically at MVP stage, this benefit is smaller and the extra fee is harder to justify.
What Actually Matters More Than the Fee Difference
- SDK and documentation quality — a gateway with unclear docs costs you development hours that dwarf a fractional fee difference at MVP transaction volumes
- Subscription support — if you’re billing recurring revenue, check the gateway’s native support for proration, plan changes, and dunning rather than building that logic yourself
- Tax/compliance handling — decide early whether you want to manage sales tax yourself or pay a merchant-of-record gateway to handle it
- Migration cost if you switch later — moving active subscriptions and stored payment methods between gateways is real engineering work, so this is a decision worth getting right the first time, not treating as reversible
Making the Call for Your MVP
For most software MVPs without a specific reason to choose otherwise, Stripe remains the default recommendation — see what Stripe integration for your MVP actually involves for what that looks like in practice, and what payment gateway integration actually costs for a cost breakdown that applies across gateways. The exception is a product with a clear international-tax need (favoring Paddle) or a consumer audience that specifically expects PayPal as an option.

Is Stripe more expensive than PayPal for a startup?
Their standard rates are close — both charge around 2.9% + a fixed fee per transaction — so cost is rarely the deciding factor. The bigger difference is documentation quality and integration flexibility, where Stripe has an edge for custom software products.
When does Paddle make more sense than Stripe?
Paddle acts as a merchant of record, meaning it handles sales tax and VAT compliance across regions for you — worth considering if you're selling a SaaS product internationally from day one and don't want to manage tax compliance yourself.
Does switching payment gateways later cause problems?
It's a real migration effort, not a config change — customer payment methods, active subscriptions, and billing history need to move over. It's manageable, but worth choosing carefully upfront rather than assuming a costless later switch.
Which gateway has the best developer documentation?
Stripe is widely regarded as having the strongest developer documentation and SDK support of any payment gateway, which is a real factor for MVP speed since less time gets spent decoding unclear API references.
