Accounting Machine System
The IBM accounting machine (left), keypunch and sorter (right) were the main ingredients of a punched-card data processing system up until the late 1960s. After keypunching, the cards were sorted into account number sequence, and the accounting machine printed the details and accumulated the totals. (Image courtesy of IBM.)

An accounting machine, or bookkeeping machine or recording-adder, was generally a calculator and printer combination tailored for a specific commercial activity such as billing, payroll, or ledger.[1][2] Accounting machines were widespread from the early 1900s to 1980s,[3] but were rendered obsolete by the availability of low-cost computers such as the IBM PC.

This type of machine is generally distinct from unit record equipment (some unit record machines were also called accounting machines).
