Accpac, Sage 300, or Something Else? We Know Them All.

This software has gone by a lot of names over the years. Depending on when you first installed it, you might know it as:

ACCPAC Plus / ACCPAC for DOS — the original versions

Accpac for Windows — the Windows-based version released in the 1990s

Accpac Advantage Series — a mid-market edition targeting growing businesses

Sage Accpac ERP — after Sage Group acquired the product

Sage 300 ERP — the rebrand in 2012

Sage 300 — the current name

Sage 300 cloud — the hosted/subscription version

No matter what you call it, the underlying platform is the same. Our team has worked with every version — whether you’re running a 15-year-old Accpac installation or the latest Sage 300 cloud release.
