Why is there a platform commission?

Supadir charges a platform commission on payments your listing owners make to you: 7% on the Professional plan, 4% on the Business plan. This is on top of the monthly platform subscription. At first glance, that might look like a double cost. It isn’t — and understanding why is important before you set your listing prices.

​

What the commission actually covers

The commission covers all Stripe transaction costs on your behalf. Stripe charges for every payment it processes. This includes card processing fees, invoice generation, subscription management, payout transfers, and dispute handling. These costs are real, and on a typical European card they amount to roughly 1.4% + €0.25 per transaction. Supadir absorbs all of these costs from the commission it takes. You don’t see separate Stripe fees on top — what Supadir deducts is the total cost.

​

What you get for those few percent

This is where the comparison to alternatives matters. Most directory platforms give you a website. Supadir gives you a complete financial engine — the same class of billing infrastructure that marketplace companies spend months and tens of thousands of euros building from scratch. Here’s what runs automatically, without any intervention from you: Recurring subscriptions. Listing owners subscribe to your plan and are charged automatically every month or year. You don’t send invoices, chase payments, or manually renew anything. Automatic invoicing. Every payment generates a Stripe-hosted invoice, automatically sent to the listing owner. VAT, billing details, PDF download — all handled. Direct bank payouts. Collected funds are automatically transferred to your connected bank account on Stripe’s standard payout schedule. No withdrawal requests, no manual transfers. Failed payment recovery. When a card payment fails, Stripe automatically retries it and sends reminder emails to the listing owner. You don’t need to chase anyone. Pro-rata refunds on catalog closure. If you ever close your catalog, Supadir can automatically calculate and process proportional refunds to listing owners with active subscriptions — based on the days remaining in their billing period. This is a legally and ethically complex calculation that happens automatically. Upgrade and downgrade handling. When a listing owner changes their plan mid-cycle, Stripe handles the proration calculation and charges or credits the difference. Automatically.

​

The cost of building this yourself

If you were to build the same infrastructure on a WordPress plugin or a cheaper SaaS platform that doesn’t include payment automation, here’s what you’d be looking at: The commission doesn’t pay for a feature. It pays for the ongoing operation of infrastructure that would cost you thousands of euros and months of development to replicate — and ongoing maintenance to keep running.

​

How to think about it when pricing your plans

Because Supadir absorbs Stripe fees, you can price your listing plans without worrying about per-transaction costs on top. If you charge a listing owner $20/month on the Professional plan:

• Supadir takes 7% = $1.40
• Stripe transaction costs are covered within that 7%
• You receive ~$18.60

There are no additional line items. No “plus Stripe fees”. No surprises at month end.

Summary

You’re not paying a commission on top of a payment processor. You’re paying for a fully automated marketplace billing engine that replaces weeks of development work and multiple third-party tools.
