Easier way to collect money for business through online platform? -

I can t begin to describe how many hours I spend on the phone trying to get other small businesses, like a Taxi service, to pay our small business for our services. I was thinking that there must be an easier way to get them to sign up at PayPal or something and then we could just deduct the money when needed. Is there a good way to do this? I m very tired of calling someone s BS about sending checks and such. Thanks!

Sign up for an ACH drafting service. You basically have them sign a bill of sale that they will be debited each month, or periodically. You can then electronically draft them when money is owed. You can also do this with some credit card processing systems.
