FAQ's
Is it really FREE?
Yes, companies never pay us a penny. We charge a small 2% booking fee to the user, meaning your success = our success.
The only fee your business pays is Stripe’s processing fee: 1.5% + 25¢ per transaction.
To be fully transparent, we’ve created a calculator so you can see the exact cost. Just note, this goes to Stripe, not Wunderbook.
Keep an eye out for platforms that hike up these fees and still charge you a monthly subscription.

No contracts. No commitments. Just register, connect Stripe, and start taking payments. If we don’t add value, walk away – no hard feelings.
Can I have more than 1 account
Absolutely and we actually recommend it. Multiple accounts allow you to take full advantage of our geo-targeting feature, which shows users the businesses closest to them first.
More local visibility = more bookings.
We can also link your accounts for easier management across locations — making it simple to switch, monitor, and grow each business.
