Powers-Samas was a British company which sold unit record equipment.

In 1915, Powers Tabulating Machine Company established European operations through the Accounting and Tabulating Machine Company of Great Britain Limited. In 1929, it was renamed to Powers-Samas Accounting Machines Limited (Samas, full name Societe Anonyme des Machines a Statistiques, had been the Powers' sales agency in France, formed in 1922).[1] The informal reference "Acc and Tab" would persist.[2][3][4]

During the Second World War it produced large numbers of Typex cipher machines, derived from the German Enigma, for use by the British Armed Forces and other government departments. In 1959, it merged with the competing British Tabulating Machine Company (BTM) to form International Computers and Tabulators (ICT).
