I had been using PayPal for online payments, but I will be switching over to a service called Venmo. It's a free app and there are no fees involved. It works like an escrow company; you transfer the money from your bank and it holds it until I transfer it to my account. Quick, safe, and easy. For your convenience, I can also use a Square Credit Card reader. However, please note that use of that service will require an additional 3% charge.
