If you want to keep your business running smoothly you have to properly manage your cash flow. Even if you hire an accountant or a bookkeeper, you still need to understand basic money management principles. You also need to establish a system for how customers will pay you? cash, personal checks, debit cards, credit cards, online payments. You should also figure out the terms of debt collecting in the event that a customer doesn't pay?
The first thing you're going to do is open a commercial bank account with a bank that you trust. When you go to set up your account, be sure to bring personal identification and the business license and name registration papers (these are required), as well as any other documentation you think you might need. It might also be wise to have the bank attach a line of credit to the account so that you have a way to make purchases during the early stages of your business (before the money starts coming in). You can also ask about any other small business services your bank might have.
Now you need to figure out how your customers will pay you. I suggest giving them as many options as possible. Customers these days expect it. There are certain expenses involved with providing customers with various payment options, like transaction fees or merchant fees, but not allowing them to pay through debit, credit, online, etc. will likely result in fewer sales. Do what you can to provide enough options to keep your customers satisfied, but if you have to pick and choose then here is a breakdown of some popular payment methods:
One thing to emphasize when it comes to payment methods is your payment terms. They should be clearly established and cover topics such as deposits, extending credit and progress payments. Your payment terms should be printed on payment communications like invoices and account statements.
Sooner or later you will inevitably be forced to deal with late payment or nonpayment issues. For such cases you'll need to consider late-payment fees and what your course of action is when non-payment occurs. Start by sending letters, emails or telephone calls, whatever it takes to get your money (without threatening the customer of course). If all else fails, you can always take the customer to small claims court.
