Your business pays an electricity bill every single month. The invoice arrives, it gets approved, it gets paid. But here's a question most business owners have never been asked: do you actually know which tariff your electricity account is billed under?
If you paused at that question, you're not alone. The vast majority of South African business owners and financial managers have no idea. And that's not a character flaw — it's a structural problem. Utility billing in South Africa is complex, opaque, and changes frequently.
The problem nobody talks about
Here's what the data tells us: 1 in 5 South African business accounts contains at least one billing error. And 1 in 4 businesses is on the wrong tariff category entirely — meaning they're being billed at the wrong rate for their consumption profile, every single month, year after year.
OptiRate has identified R 39,662,305 in savings and uncovered R 43,974,771 in billing errors across 5,549 accounts analysed in South Africa. These aren't edge cases. This is what happens when you look closely at the average South African business utility account.
Why does this happen?
Tariff schedules are complex and change annually. Eskom's Megaflex, Miniflex, Homelight, and Businesslight tariff categories each have different rate structures, time-of-use periods, and demand charge methodologies. When a business's consumption profile changes, the tariff that made sense three years ago may no longer be optimal.
Municipalities make mistakes. Meter readings get estimated when access is difficult. Calibration errors go undetected. New tariff schedules get applied incorrectly during system migrations. The City of Tshwane, City Power, eThekwini, and others have all had high-profile billing errors in recent years.
Nobody's checking. The businesses that do try to verify their bills spend hours on spreadsheets — and still miss things, because the full picture requires live tariff data, historical consumption benchmarks, and meter-level verification simultaneously.
The first step is knowing the question exists
You can't fix a problem you don't know you have. OptiRate analyses your utility bills against live tariff schedules and flags errors automatically. Most businesses see their first findings within the first billing cycle. The audit doesn't cost you anything upfront — if we find savings, you share in them.
