Frequently Asked Questions
01 What payment processor has the lowest fees for startups?
Braintree has the lowest standard rates at 2.59% + 49¢ with no monthly fees, slightly beating Stripe's 2.9% + 30¢. However, Stripe's superior developer experience and ecosystem often provide better value despite the marginally higher fee. Square offers 2.6% + 10¢ but is optimized for businesses with physical sales.
02 Can I use Stripe if I haven't incorporated my startup yet?
Yes, you can use Stripe as a sole proprietor using your Social Security Number in the US. However, Stripe Atlas can help you incorporate a Delaware C-corp for $500 and includes a Stripe account with waived fees on your first $5,000 in processing, making it a popular option for first-time founders.
03 Do I need a merchant account as a startup?
No, modern payment processors like Stripe, Square, and Braintree are payment service providers (PSPs) that handle merchant accounts for you. This eliminates monthly fees, long approval processes, and complex contracts. Traditional merchant accounts from banks are outdated for most startups and only make sense at very high volumes ($1M+ monthly).
04 Which payment processor is best for SaaS startups?
Stripe is the clear leader for SaaS startups due to Stripe Billing's sophisticated subscription management, usage-based billing, proration, and trial period handling. Braintree also supports subscriptions but with fewer features. Square is not optimized for SaaS recurring revenue models.
05 When should a startup switch from Stripe to a cheaper processor?
Consider switching when you're processing $500K+ monthly and have a technical team. At this volume, Checkout.com or Adyen can offer interchange++ pricing that saves 0.3-0.5% compared to Stripe's flat rate. However, factor in migration costs, engineering time, and the value of Stripe's ecosystem before switching.
06 What's the difference between free and paid tiers?
Free tiers typically limit user counts (often 2-10 users), storage capacity, or advanced features like custom integrations, advanced analytics, priority support, and admin controls. Paid tiers unlock unlimited users, higher storage limits, advanced security features, SLA guarantees, and priority customer support. Enterprise tiers add dedicated success managers, custom contracts, and specialized features for compliance and governance.
