Your largest client is not your most profitable

The problem it solves

Nearly every company has one account nobody questions: the one at the top of the sales report, the one the owner mentions when someone asks how business is going, the one that gets protected whenever something has to give. Its price was set years ago, when it ordered half as much. Since then it has earned deliveries off the route, changes that never get billed, the owner's immediate attention, and payment whenever its own internal cycle allows. None of that appears on the line the company looks at.

The income statement cannot settle the question, because it was not built to. It adds up all the revenue, subtracts all the cost and reports a result for the whole. Staff hours lost to rework, the repeat delivery, the administrative time spent untangling one complicated order and the cost of money sitting still while that client takes its time all live inside overhead, spread across everything, attached to no one.

The consequences are not confined to the books. The company defends volume without knowing what margin travels with it, discounts to keep an account it might be better off resizing, and serves its small quiet lines worse precisely because they never ask for anything. When the large account eventually leaves, and eventually it does, it leaves behind a cost structure built to its shape. Meanwhile decisions about which line to expand keep getting made on the most visible signal available and the least informative one, which is the invoice.

What it covers

The workshop opens on a distinction that gets blurred constantly: gross margin, contribution margin and net result are not three depths of the same measure, they are three different questions. The first hour establishes which one answers what and which decision each belongs to, working on the revenue and cost structure the companies in the room bring with them. This is not a pricing workshop. It is the work that has to exist before a price can be revisited on any solid basis.

The middle block is cost allocation. In a group exercise participants assign direct costs and staff time to one of their own products or clients, and argue through the allocations that have no obvious rule, which is most of them. The standard being sought is not the exact one, which exists only in textbooks, but the one a company can defend to itself and apply the same way every month rather than adjusting it whenever the answer is inconvenient.

From there the session measures cost to serve, which is usually where the surprises are. On a worksheet each participant estimates what a demanding client genuinely costs: the extra deliveries, the rework, the attention and administration, and the days that client takes to pay. Those pieces feed the contribution margin by line and the break-even point for a single line, which tends to sit somewhere other than where the company assumed it did.

The closing block turns the analysis into a decision, since a margin that is known and unused changes nothing. The group works through the three routes available when a line does not pay its way, changing the price, changing what is included, or stepping away from it, and examines what each one does to used capacity, to the commercial relationship and to the rest of the operation. Participants leave with their lines ranked by what they contribute and with a method they can rerun when costs move.

What participants learn

• Distinguish gross margin, contribution margin and net result, and the question each one answers.
• Allocate direct costs and staff time to a product or a client on a basis the company can defend.
• Calculate the cost to serve: extra deliveries, rework, attention, administration and slow payment.
• Calculate contribution margin and the break-even point for a single line.
• Evaluate the three routes out of an underperforming line: change the price, change the scope, or step away.

Agenda

1. 01Revenue, margin and result: three different questions
2. 02Direct costs, indirect costs and an allocation you can defend
3. 03What a demanding client really costs to serve
4. 04Contribution margin by product or service line
5. 05Break-even and the capacity you are actually using
6. 06Inherited prices that no longer cover the cost
7. 07What to do with a line that does not pay its way

What the organisation leaves with

• A written cost allocation standard, already applied to the lines or clients the company brought to the session.
• Contribution margin for at least one line or client, with the calculation documented so it can be repeated monthly.
• A reviewed list of clients or lines ranked by what they contribute rather than by what they bill.
• Leadership will be able to recognize when a large account is being carried by the rest of the business, before defending it out of habit.
