Is it possible to charge a fee for ServiceM8 customers paying with credit card through stripe?

I’d like to have the option to pass on the credit card fees to clients who chose to pay by credit card. I don’t want to charge clients who pay by bank transfer.

Since I don’t know what method of payment a client will choose, I can’t add the fee as a line item on the invoice.

So, it needs to be an added percentage put on top of the invoice price.

For me, stripe processes the credit card and I also have Xero integrated.

I asked ServiceM8 support and they told me I should just increase all of my prices. They don’t have this feature on their radar.
