Sage 50 is a set of accountancy and payroll products developed by Sage Group aimed at small and medium enterprises. Sage offer different products under the Sage 50 name in different regions. The product name originally derives from the UK and Ireland version of the product where the number 50 indicated that it was aimed at companies with up to 50 employees. The products are described as cloud-connected reflecting the remote working and online capabilities of the range. UK/Ireland version In the UK and Ireland there are currently four products under the Sage 50 banner; Accounts, Payroll, HR and P11D. Sage 50 Accounts was the market-leading accounting solution for many years. The product currently known as Sage 50 Accounts has its origins in some of the earliest solutions that Sage produced. A direct relative of the current product is the Sage Sterling range which became available in September 1989 as a replacement for Sage's successful Businesswise Accounts range. Sage Sterling was available for DOS and in the early 1990s for Microsoft Windows. The product was re-branded as Sage Sterling +2 and in 1993 a version of the product became available for Apple Macintosh. By 1993 Sage Sterling was market leader having accounted for 62.5% of the integrated accounting software market.

In 2023 the product branding was simplified again back to Sage 50. The UK/Ireland Sage 50 products are developed in Newcastle upon Tyne, England.
