If you are looking at receiving your money through the gift option, so you don't get charged for window cleaning work.
This may be ok for those who have money in the paypal account to pay you, but if not or it could be your customers do not have a paypal account.
Before payment is sent the payer will have two options, send extra to cover the pay pal fees or send the amount a paypal will deduct the fee from receiver.
This will get customers moaning, just claim charges back when doing your book for mr tax man.
