How to add two products to one payment link - trying to find a way to add a fixed transaction fee to every purchase (Stripe)

I am trying to set up a transaction fee as part of this project. My client has this set up within their stripe (and can do so legally) that the stripe transaction fee is charged to the client. 

I am suprised this isn't an option within Squarespace but also that the integration with Stripe doesn't pull this info through to the checkout.

I am open to creative ideas here and some css to get the desired process but am a bit stuck! 

The customer journey through to purchase is primarily through an events calendar where customers can go straight to checkout. That said they can at this point still click on the product and go straight to checkout from there. (Something I am happy to disable if that is possible!) 

I thought one way around this was to create a product called 'Transaction Fee' and add two products to one payment/checkout link but it doesn't seem to be as simple as I was hoping!  

Anyone ideas how I can make this work?

Squarespace wasn't designed with commercial B2B transactions in mind, so doesn't include a method of applying surcharges to online transactions. This situation is therefore usually managed by passing on the costs to customers through an increase in the headline price. 

I understand that but is there no way I can show it as a seperate line item through having it as a product? 

It is frustrating it doesn't just pull through the set up from Stripe?

I'm not saying it is impossible, but I wouldn't recommend this approach to a client unless they want to pay ongoing maintenance to a developer to keep the solution functional and up-to-date. 

I hope this helps 🙂

How would you suggest doing this?
