I work for a client based in Great Britain, and I will be sending him an invoice for graphic design work that has already been completed. The payment will be made via PayPal, and he is willing to cover the payment gateway charges of PayPal.
So when I make the invoice, how shall I write the entry of the payment gateway charges in the invoice? What is the best procedure to follow when defining the additional charge on an invoice so that all transactions remain transparent to the client?
Your advice will be greatly appreciated. Thank you.
