How Stripe Connect Payouts Work for STL Sellers

Stripe Connect lets a marketplace support paid STL downloads without building its own payout system. Sellers onboard with Stripe Express, buyers pay through Checkout, and the site grants file access only when payment events confirm the order.

Why Stripe Express is used

Payout setup requires sensitive identity and bank details that belong with a payment provider.

• The marketplace starts onboarding; Stripe collects and verifies the required payout information.
• Sellers return to 3DPrintedCarPart.com to manage listings after onboarding.
• If Stripe needs updated details, the seller flow can generate another account link.

How checkout unlocks downloads

Paid files should remain gated until the payment has completed.

• Active paid listings create Checkout sessions for authenticated buyers.
• Successful payment creates or preserves a download entitlement for the listing.
• Refund, dispute, and expiration events keep entitlements aligned with payment reality.

How to explain payouts

Good seller copy is accurate without overpromising.

• Mention the platform fee target, but leave room for Stripe processing, taxes, refunds, disputes, and payout timing.
• Do not promise instant payout or fixed net revenue.
• Point sellers to /sell and Stripe status for operational details.
