Hourly IT billing sounds fair in theory. In practice, it creates a perverse incentive where you avoid calling your IT provider — even when something's wrong.
I want to tell you about a client we took on last year. Medium-sized accounting firm, 18 staff, based in Sandton. They'd been with their previous IT company for three years on an hourly rate.
When I asked them how often they called their IT provider, the MD said: "As little as possible, to be honest."
That sentence should scare you if you're running a business.
The Hidden Problem with Hourly Billing
Here's what happens when you pay per hour for IT support:
Your printer starts behaving strangely. It's not broken — just intermittently failing. You think, "I'll keep an eye on it." Three weeks later it completely dies the morning you need to print 50 client contracts. Now you're paying for an emergency call, losing half a day, and scrambling to reprint everything at a printing shop down the road.
If you'd called when it first started playing up, it would have been a 20-minute remote fix. But you didn't call, because there's a meter running every time you do.
Hourly billing trains you to avoid your IT provider. That's the fundamental problem.
What a Retainer Changes
With a fixed monthly retainer, the calculation flips completely.
You're paying a set amount regardless of how many times you call. So when that printer starts misbehaving, you call immediately. The fix is fast, the disruption is minimal, and the problem never escalates.
Small issues get caught early. Early issues are cheap and quick to fix. Cheap and quick fixes mean your staff keep working and your month stays predictable.
Budget Certainty Is a Genuine Business Advantage
Cash flow is everything for a small or medium business. When your IT bill varies wildly from month to month — R3,000 in a quiet month, R18,000 when something big breaks — it makes forecasting genuinely difficult.
With a retainer, you put one number in your budget. Every month. Forever. You know exactly what IT costs, and that number never surprises you.
That's not just a billing preference. That's a planning advantage.
What You Should Ask Any IT Provider
If you're evaluating IT companies, ask them this: "What does a bad month look like for my invoice?"
If they give you a number that's significantly higher than a good month, think carefully about whether that billing model is really serving you — or serving them.
The best IT support relationship is one where you never hesitate to pick up the phone. A fixed retainer is the only model that makes that possible.
