Nobody buys an ERP because they want one. They buy it because stock, production and the general ledger have stopped agreeing with each other, and the spreadsheet holding it together has become a person's full time job.
The honest thing to say about this category is that implementation cost usually exceeds licence cost, often by a factor of two or three, and the implementation partner matters more than the badge on the software. A well implemented mid tier system beats a badly implemented tier one system every time. We name the local partner ecosystem in each review because in South Africa that is the deciding factor.
We assess local statutory reporting, multi warehouse and multi company handling, manufacturing depth where relevant, and whether the product has a genuine South African install base or is being sold here for the first time. Load shedding gets a mention too, because for a manufacturer a system that survives an unplanned power cut without corrupting a production run is worth real money.
