What would you do?

Hey! Here's a case that we currently have. I wonder what would you do? 👉 Setup: You are a SaaS business. You've set up an automatic subscription payment system. All of your clients are using cards to pay, which fits very well into your system, you create automatic invoices and all that jazz. You are about to sign a new client. You will be billing them on a monthly basis. They will be paying more than your average customer. 👉 Problem: They can't or don't want to pay by card. They prefer to wire the money through a bank transfer. Now... this goes around all the systems you've set in place and you'll have to manually handle this for them every month. Automatic recurring payments are out of the question. Should you set this precedent? 👉 What would you do? a) Insist on card payments b) Accept the bank transfer as payment c) Accept a bank transfer for the first month to close the client ASAP. Demand that each subsequent payment is by card d) Other ideas?
