Activity-Based Costing Reveals True Profitability Issues
Uncover the hidden costs eroding your margins
Most finance teams trust their gross profit numbers.
And to be fair, GP is usually solid. ERP systems are built for it. They track revenue against direct costs, and for the most part, they get that right.
But here’s the catch: GP is where the real story ends.
Between GP and net profit sits a black hole called overheads. And that’s where the truth about your profitability gets lost.
Overheads aren’t abstract. They’re the cost of serving customers - the account management, the reporting, the change requests, the logistics, the endless service calls. But because we don’t connect those costs back to customers, they disappear into a bucket.
That’s where Activity-Based Costing changes everything.
By tying overheads back to the customers and activities that actually consume them, ABC shows you what’s really going on:
1️⃣ A client that looks healthy on GP might be a loss-maker once you factor in the service hours.
2️⃣ Some accounts are over-serviced - you’re giving away more than you’re charging for.
3️⃣ Others just need a price reset to bring them back into the black.
4️⃣ Smaller customers can often be served more efficiently through a portal or agent model.
5️⃣ And sometimes the problem isn’t the customer at all - it’s an inefficient department you couldn’t see before.
This isn’t about punishing customers. It’s about seeing the cost-to-serve clearly so you can make better choices.
ABC doesn’t add complexity. It removes the guesswork. It stops profitable customers from subsidising the unprofitable ones.
And once you know the truth, you can decide: adjust pricing, redesign service, protect strategic clients, or cut the ones that don’t belong.
