Synergy Holdings expects to report a decline of about 1.01c a share for the six months to August, a 59% decline from the same period last year.
The accounting consulting and software development house says in a trading update that there has been a decrease in the number of upgrades of ACCPAC DOS to ACCPAC Windows.
Last year's results also showed the benefit of an assessed tax loss which was exhausted by the February year-end.
In addition, it says, it incurred substantial costs related to opening a branch in Cape Town.
The group says its board is finalising its review of the results, which are expected to be published on 4 November.
For the six months to August last year, Synergy achieved headline earnings of 1.7c, up from 1.17c previously. Net after-tax profit rose from R0.73 million to R0.99 million.
