Bookwhen does not charge you anything beyond your chosen subscription cost.
However, if you accept online payments then you need to secure the services of one of our approved payment gateways. Your chosen payment gateway will then take a small fee per transaction for using their payment infrastructure.
Payment gateway fees
The available payment gateways you can integrate with your Bookwhen subscription are (Only one payment gateway account can be integrated with one Bookwhen account):
The flat fee - is a set amount collected from each transaction
The percentage fee - is the % of the transaction total that is also collected
With Bookwhen, you can pass this fee onto your customers if you wish (if you're in the EEA please make sure you read this first).
If you are looking for information about how payments work on Bookwhen you can read our support article here, and you can find information about the countries and currencies supported by each payment gateway here.
