The original product, EasyBusiness Systems, was developed for the CP/M operating system^[8] in 1976 by Don Thomson, Ted Comfoltey, Keith Wales, and Norm Francis of Basic Software Group^[9] and distributed by Information Unlimited Software. This was ported to MS-DOS and the IBM-PC in 1983.^[9][10]

Computer Associates acquired Information Unlimited Software in 1983^[11][12][13] and ran it as an independent business unit.^[14][15] Easy Business Systems added payroll processing in 1984 and supported multiuser networking at this time.^[16] In 1987, it implemented a multi-window interface to allow moving between different modules.^[14] Easy Business Systems was renamed Accpac Plus in 1987 with the release of version 5.^[17] Accpac became popular in Canada with support of Canadian public accounting firms that would sell and support the software.^[15] The name Accpac is an acronym for 'A Complete and Comprehensive Program for Accounting Control'.^[18]

The first Windows version, CA-Accpac/2000, popularly known as ACCPAC for Windows, was developed in the early 1990s and released in October 1994.^[19][20] The Windows version marked the move to client/server and was developed with all new code in COBOL with Computer Associates development tools (these components were redeveloped in 2001 in Accpac Advantage Series with a core business layer developed in C and a user interface layer developed in Visual Basic).^[21][22]

In October 1996 ACCPAC for Windows 2.0 was released.^[23] In August 2001, the company presented ACCPAC Advantage Series 5.0, its first web-based version.^[24] The web interface was rebuilt in Sage 300 2016 for cross browser support, running on IIS with ASP.Net,^[25] a web API was added in the 2017.^[26][27]

Sage 300 initially ran on Btrieve Databases^[28] and then supported a variety of database backends.^[29] Since Sage 300 2016 only the MS SQL database is supported.^[28]

Sage Software acquired Accpac from Computer Associates in 2004.^[30] Sage renamed it Sage Accpac ERP in 2006,^[31] then Sage ERP Accpac in 2009. Sage dropped the Accpac name in 2012 when it was renamed to Sage 300 ERP.^[32]
