Bookkeeping does entail a lot of math – regular monitoring of cash, paying bills, and tracking income – but anyone with strong math skills can do it, as long as they learn the basic bookkeeping practices.

A COA is a list of the account names a company uses to label transactions and keep tabs on its finances. You use a COA to organize transactions into groups, which in turn helps you track money coming in and out of the company. COAs are typically made up of five main accounts, with each having multiple subaccounts.
