Yes, the but the fees vary depending on what card your customers uses. 

• You can find Stripe's fees here. 
• Stripe transfers funds to your account on a 7day rolling basis.
• You bear the cost of the fees (not your customer). i.e. If you invoice your customer £100 (VAT included), then you will get £100 - Stripe fees into your bank account.

Note: Solna doesn't take any mark up on the fees unlike other invoicing platforms.
