SnapAccounting
SnapAccounting was a commercial software package for the PC written by Joe Schoemann Computers in Johannesburg, South Africa in the early 1980s.
It was written in dBase 3 and compiled with Clipper (programming language). It had a DOS .bat file installation program that used the Company's Name as a security against software piracy, which was rampant in South Africa in the 1980s.
SnapAccounting was one of the earliest turnkey accounting packages available in South Africa.
There were SnapAccounting modules for Debtors, Creditors and General Accounting. A Stock module was added later.
Special customized version existed for garages and butchers that integrated all 4 packages and included a Balance Sheet module.
