Single-entry book keeping is an easy system of accounting, in which a single line is utilized to record each exchange. A book-keeping book or statement is often used to record financial entries as they happen with credits or debits entered once. Single-entry book-keeping is usually matched against that of a check-book register or a straightforward fiscal statement.
It is not uncommon with easy book-keeping systems that parentheses are used to reflect negative transactions ,eg withdrawals or payments. Money coming in, like payments or credits, isn’t besieged by parentheses. The parentheses are a simple way to distinguish between cash being spent, or costs, and money being deposited, called income. Money and costs can be totaled by week, month, or perhaps year using any single-entry system. Despite being called single-entry, there’s more than one methodology of this accounting system. It’s very important that all info for each entry is recorded on a single line for it to be considered single-entry book keeping.
