Stripe Connect Express vs Custom Platform Fees

Stripe Connect has two main account types for platforms. Express: $2/month per active connected account + 0.25% on payouts + standard Stripe processing (2.9% + $0.30). Stripe handles onboarding UI and compliance. Custom: 0.25% on payouts + processing — no monthly account fee, but you build your own onboarding flow and have more compliance responsibility. For low-volume platforms with <400 active accounts, Express can actually be cheaper than Custom due to reduced development costs.

When does Stripe Connect Custom become cheaper than Express?

At $2/month per active account, Express costs $200/month for 100 active accounts, $2,000/month for 1,000, and $20,000/month for 10,000. The payout and processing fees are identical for both. So if your development cost to build Custom onboarding is under $2 × (number of active accounts) × 12 months, Custom may save money over time — but only if you have a large, stable base of active connected accounts.

What does 'active connected account' mean for Stripe Connect billing?

Stripe charges the $2/month Express fee for each connected account that processes at least one payment in a given month. Connected accounts with zero activity in a month are free. This means your monthly cost scales with usage — a new marketplace with 500 registered sellers but only 50 actively selling pays for 50 accounts, not 500.

Can I switch from Stripe Connect Express to Custom?

Yes, but it requires a migration. Express accounts use Stripe's hosted onboarding flow and dashboard — migrating to Custom means building your own equivalent. Stripe provides migration tools, but it's a significant engineering effort. Many platforms start with Express to launch faster and migrate to Custom once they have sufficient volume to justify the development investment.
