Stripe Connect Integration for SaaS: What You Actually Need to Know

If your SaaS platform needs to collect payments on behalf of users, you’re not just building a billing feature — you’re building a financial product. And unless you want to spend 6 months dealing with KYC rules, fraud detection, and tax forms, the only sane way to do it is Stripe Connect.

We’ve integrated Stripe Connect into tournament apps, service marketplaces, B2B tools, and HIPAA-compliant platforms. Here’s what actually matters when you’re setting it up — and how to avoid common mistakes.

Know Which Connect Mode You Need

Stripe Connect has three modes — but only one is probably right for your SaaS:

We recommend Express for 90% of platforms. It balances control with compliance and makes onboarding easier.

Account Creation and KYC = The Bottleneck

Every connected account must pass:

• Identity verification (legal name, DOB, SSN or EIN)
• Bank account or debit card link
• Email + country matching

Plan your UX flow around this. You’ll want:

• A clear call to action for “Connect Bank Account”
• Status indicators: Pending, Verified, Incomplete
• Fallback support when Stripe blocks onboarding

Stripe’s dashboard will give you webhooks for status changes — use them.

Handle Payouts (and Delays) Transparently

Your users will want to know:

• How often they get paid (daily, weekly, manual)
• What their balance is right now
• What fees they’re paying

Build:

• A “Payouts” screen that pulls from Stripe’s /payouts and /balance APIs
• A breakdown of fees per transaction (Stripe + your cut)
• Alerts when payouts fail (wrong bank info, risk blocks)

Implement Platform Fees and Split Logic Correctly

You can:

• Charge a flat fee (e.g. $5 per job)
• Charge a percentage (e.g. 10% of the sale)
• Or combine both with custom logic

Use application_fee_amount in your payment intent
Or set up destination charges for full control
Log every fee and payment split in your DB — Stripe is not your source of truth

Don’t Forget About Taxes and 1099-Ks

If your users earn money through your platform:

• You may be required to issue 1099-Ks (in the U.S.)
• Stripe will do this automatically if you use Express or Custom mode

Set capabilities: { transfers: true, tax_reporting_us_1099_k: true }
Confirm legal entities during onboarding
Provide access to Stripe’s prebuilt 1099 dashboard (you don’t want to build this)

Final Thought

Stripe Connect integration for SaaS isn’t a plug-and-play module — it’s infrastructure for your entire revenue system.

If you’re building a platform where users earn or collect money, this integration is the product. It has to be frictionless, compliant, and bulletproof — or you’ll get support tickets, angry users, and account shutdowns.

We’ve done it before, and we can help you get it right.
