Selling web design services as an Individual question

Hi. I make a living by selling web design services ( to companies, doctors, etc), but lately more and more of them ask for a fiscal bill to deduct their expenses with the company. That's understandable. But I, as an individual I can't provide that fiscal bill, therefore I lost quite a bit of clients on this.Right now I receive my payment either via WU or a Wire Transfer from them.
My question is: If I use a payment processor like Stripe for these services, can they use that receipt they receive on email ( from Stripe ) to deduct their expenses? Thanks guys!
