The biggest concern of any businessman is to have a healthy cash flow. If their is no cash coming in , the business might run on borrowed money from your family and friends, but it won’t last long.
Dealing with non-paying customers is a pain in the neck. I have had quite a few of those, but at the end of the day that’s just how they are. But that doesn’t mean you need to put up with it.
Here is how I deal with them.
1. I send a very kind email, and sms reminding them of the payment
2. If I don’t get any response, I pay them a visit after a few days to remind them of the bill again
3. If there is still no response, or action. I cancel their services, and do not provide them any more products/service.
4. I blacklist them and avoid them in the future. I would rather lose a big customer who orders every week and pays late, over one who buys once every few months and pays on time.
