Many small start-up businesses are off and running before any record system has been set up. There is money deposited into the new business checking account, some from invested funds and some from sales. Money has been paid out for equipment and supplies, some by check and some by cash out of pocket or from sales receipts.

This informal method of cash receipts and disbursements needs to be formalized. The bookkeeping system does not need to be complicated. In most cases, you can continue to operate much as you have. You just need to do it in a way that leaves a few more tracks.
