Slow Paying Customer

Losing an account can be a result of your own doing. If you find that the time it takes to get paid is too long and getting even longer all the time, you may need to reconsider that company's business. Obviously, you will make all the efforts you can to resolve the situation but sometimes you just can't seem to do it. It is hard to break someone else's habit once they have been doing it for a while.

If the longer payment time leaves you in a no profit situation or a break even position, it's not worth it. You have your own bills to pay and the money you have made needs to be there. Cutting off or firing a regular account will almost bring tears to your eyes but sometimes it has to be done. You can't put your entire business in jeopardy because of one or two customers, regardless of how big the account is. Your first responsibilty is to your company and your employees so take action.
