Leveraging Activity-Based Costing for Enhanced Financial Insights

Roger Knocker • June 5, 2026

See the true cost to serve and uncover where profitability is really created.

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 is the catch. GP is where the real story ends.


Between GP and net profit sits a black hole called overheads. That is where the truth about your profitability gets lost.

Overheads are not abstract. They are the cost of serving customers, the account management, the reporting, the change requests, the logistics, the ongoing service calls. But because we do not connect those costs back to customers, they disappear into a bucket.


That is where Activity-Based Costing changes everything.


By tying overheads back to the customers and activities that actually consume them, ABC shows you what is 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 are giving away more than you are 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 is not the customer at all, it is an inefficient department you could not see before


This is not about punishing customers.

It is about seeing the cost to serve clearly so you can make better choices.


ABC does not 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 do not belong.
