Single-entry bookkeeping

Single-entry bookkeeping is a way of keeping track of money coming in or out of a business. It means that for every transaction, like when a customer pays for something or you buy something for your business, you only make one entry in your books. You record information like how much money you got, who it was from, and when it happened. This helps you to keep an accurate record of your finances.
