I was just made aware of this:
4.d Sellers may not charge a surcharge for accepting PayPal as a payment method.
4.6 No Surcharges. You agree that you will not impose a surcharge or any other fee for accepting PayPal as a payment method. You may charge a handling fee in connection with the sale of goods or services as long as the handling fee does not operate as a surcharge and is not higher than the handling fee you charge for non-PayPal transactions.
Does that mean if we invoice our customers (eg: for website work) we are not allowed to charge the extra "paypal fee" ontop of our invoice amount?
How many people charge their customers the extra paypal fee (only if paypal is used)? And, I guess.. is doing this really allowed?
(let's keep this on the topic of invoicing our own customers - not what's discussed in the other thread)
