Having a sound accounting system can be the make or break aspect of a small business. Accounting systems are different than bookkeeping. An accounting system is the how the business handles each step of the financial system of the business. This can be the sales cycle, payroll, inventory management, accounts payable, and accounts receivable management.
One of the biggest areas that is important for small businesses is having a well-established sales cycle because if you do not know how much someone owes you or who owes you money you will not be collecting any revenue. It is important to establish a system that tracks either sales or products or tracking the services you provide for your customers. One way to do this is through invoicing. Have an invoice that says the date of the invoice, when the money is owed, what the invoice is for, and number them numerically so that they are easier to manage.
