Business One is SAP's product for companies well below the scale of S/4HANA. It carries the SAP name, the SAP data discipline and a global partner network, and it is a legitimate mid market ERP rather than a cut down version of something larger.
For South African subsidiaries of international groups it is often the group standard, and the local question is implementation rather than selection.
Strengths
Financials are rigorous. The audit trail is complete, the controls are strong, and it produces the kind of reporting that satisfies a group finance function and an external auditor without argument. Inventory and production are solid. Analytics through the HANA edition are genuinely fast on large datasets.
The global partner network means support wherever the group operates, which matters for a business with operations across several countries.
The localisation question
South African VAT201, IT14SD support and local statutory reporting come through localisation packages maintained by partners rather than by SAP directly. Quality varies. This is the single most important thing to interrogate during selection: ask the partner to demonstrate a VAT201 from live data, not a slide.
Cost and complexity
Licensing is per user with professional and limited user types, quoted through the partner. Implementation is a project of several months. The system rewards being implemented properly and punishes shortcuts, and the most common failure mode we see in reviews is an under scoped implementation followed by two years of workarounds.
Who should buy it
South African subsidiaries of international groups, businesses with strong governance requirements, and manufacturers or distributors between one hundred and one thousand staff who want a globally supported platform. Confirm the local statutory reporting before signing anything.
