Currently Sars runs more than 700 approved applications, of which there are seven "core tax" applications. Any tenderer will have to find a way to port bespoke Windows applications successfully and in a cost-effective manner. Other hurdles include "usability, end-user acceptance and resistance to change", "the cost and challenge of end-user training and support", and "a frequently encountered dependency on Microsoft Active Directory".
It's a high business risk for bidders, who will have to burden the entire cost of the proof of concept themselves, with Sars making no guarantee as to whether it will even switch to Linux at all.
Sars is already using open source on its back end, having migrated its SAP system to a Linux platform in 2004. Since then, it says it has seen a "significant improvement on performance and stability". It also praises open source for being "more secure, reliable and higher-quality software", citing bug fix response times, patch management, virus risk and the ability to inspect the code as major advantages over proprietary products.
"Open-source software has reached a critical mass that has allowed it to enter the mainstream software market, and its impact is becoming noticeable in the software industry and in society as a whole. Some of our strategic vendors such as IBM, SAP in particular, are committed to using open software as a core part of their business and are investing significantly in enhancing its already impressive capabilities," says Sars.
A briefing session for interested parties will be held on February 28 at Sars's offices in Pretoria. Sars was unable to comment on interest shown in the tender at this point, but noted that the tender document has been downloaded numerous times from its website. The tender closes on March 10.
In the 2004/05 tax year, Sars collected R354,98-billion in tax revenue.
