In most executive committees, the large account is treated as a revenue question. People look at volume, at the share it represents, at year-on-year growth. Far more rarely do they look at what that account actually earns once you deduct the discounts negotiated, the logistics concessions granted, the service time mobilised and the payment terms accepted. Yet that is where profitability is decided, and it is what makes a Key Account Manager recruitment a financial decision as much as a commercial one.
In short
- A large account concentrates revenue and concentrates price pressure : volume does not protect margin, it exposes it.
- The account owner holds four profitability levers : product mix, discount level, service conditions and length of commitment.
- The cost to serve an account – logistics, pre-sales, support, financing the payment terms – stays invisible in most sales reporting.
- One point of margin lost on a major account often weighs more than the package gap between a good candidate and an excellent one.
- Protecting margin requires both a pay plan indexed on profitability and management that backs the refusal of certain concessions.
The large-account paradox
An important client brings volume, visibility and a commercial reference. It also brings an unfavourable balance of power. They know what they represent in your revenue, their buyers are professionalised, they compare, they run competitive tenders and they renegotiate every year. The classic result : the margin on a major account often sits several points below that of the average portfolio.
There is a second, structural effect. A large client tends to standardise what it buys, because standardisation is how procurement extracts price. Over time the supplier finds itself selling a narrower, more comparable range, which erodes the differentiation that justified the price in the first place. Resisting that drift – by keeping services, options and higher-value references inside the relationship – is one of the quieter parts of the account manager’s job, and one of the most consequential for the P&L.
That is not a problem in itself. The problem appears when nobody measures the gap, or when the salesperson holding the account is assessed on revenue. They will then deliver exactly what is asked : volume, at whatever price it takes. A Belgian company can consult the annual accounts filed by its clients and competitors with the Central Balance Sheet Office of the National Bank of Belgium ; that reading often changes how the balance of power looks going into an annual renegotiation.
The four margin levers held by the account owner
| Lever | What is at stake | Effect on profitability |
|---|---|---|
| Product and service mix | Selling the premium range, options, maintenance, training | The most powerful and the most discreet : it is built, not negotiated |
| Discount level | Volume rebates, year-end rebates, commercial gestures | Direct and immediate, often irreversible from one year to the next |
| Service conditions | Delivery frequency, dedicated stock, dedicated support, customisation | Cost to serve rarely re-invoiced, therefore rarely visible |
| Duration and exclusivity | Multi-year framework agreement, renewal clause, guaranteed share of wallet | Secures volume and allows dedicated investment to be amortised |
A mediocre salesperson uses one of these levers, the easiest : the discount. An excellent one uses all four, and reaches the same volume with a materially different result. The skill at work is not firmness in the final negotiation ; it is the work done during the twelve months before it, the work that makes value obvious by the time price comes up.
Cost to serve : the invisible part
The margin reported by management accounting usually stops at gross margin. What it ignores on a large account nonetheless represents substantial amounts : split deliveries at the client’s request, stock immobilised to guarantee a lead time, pre-sales hours spent on tenders, a supplier portal to feed, quality audits to undergo, and above all payment terms.
That last point deserves to be quantified, because it is the easiest to overlook. Thirty extra days granted to a client representing a significant share of revenue immobilise working capital that has to be financed. A salesperson who concedes longer terms without pricing them in one way or another has granted a discount ; it simply does not appear on the “discount” line.
The practical implication for a company director : ask for a profitability view by account, cost to serve included, before the next renegotiation round. The exercise almost always surprises, and it changes how the account owner’s mandate is defined.
The expert’s view
Archetype is a family business. Marc Diamant founded the firm in 1993. His sons Davy and Steve joined him in late 2023. That continuity isn’t an anecdote : it’s what lets us hold client relationships across 20 years without method discontinuity, without turnover wiping out file memory, without changing direction every three years to chase the latest HR trend. Stability, in a trust business, counts.
What a poor account owner costs
Before that, there is a simpler question worth asking : does anyone in the company actually know the margin on each of the top accounts? In a surprising number of mid-sized Belgian businesses the answer is no, or the figure exists but is not shared with the person who negotiates. That gap alone explains a large share of the value given away every year.
The calculation is rarely done, and it is instructive. Take an account worth a few million euros of annual revenue. One or two points of margin conceded during a renegotiation represent an amount that far exceeds the full annual cost of the role. In other words : on this kind of position, the package gap between a decent candidate and an excellent one pays for itself in a single successful negotiation.
Add to that the less visible costs of a failed hire : the months during which the account is not worked, the erosion of the relationship with contacts who have to re-explain their context, and the risk of a competitor exploiting the drift. On concentrated portfolios, that risk is the leading threat to company valuation.
That logic is what justifies working on retainer rather than on success on this kind of mandate. Our fees are fixed in advance, between 25 and 30 % of the annual package, settled in three instalments : 25 % on engagement, 25 % at the second candidate meeting, 50 % on placement. Mutual commitment is what makes it possible to see a demanding search through, with a six-month replacement guarantee and a success rate above 75 % on assignments taken through to final placement.
Portfolio concentration is a valuation issue
Any company where three clients represent a majority of revenue carries a risk its bankers, its investors and any future buyer understand perfectly well. That risk translates into a discount in a transaction, and into less favourable financing terms day to day. Reducing dependency runs through two parallel workstreams : developing new accounts, and securing existing ones through multi-year commitments.
The second falls precisely to whoever holds the strategic accounts. Turning a transactional relationship, renegotiated on price every year, into a three-year framework agreement with reciprocal commitments does not only change margin : it changes the quality of the order book and, in consequence, the value of the business. That work is long, political and invisible in monthly reporting, which is exactly why you need someone capable of doing it.
Aligning pay on profitability, not on volume
If margin matters, it has to appear in the variable plan. Indexing an account owner’s pay on revenue amounts to financing the discounts they grant. Indexing on the account’s gross margin, adjusted for cost to serve where possible, immediately produces different behaviour : the salesperson defends the mix, questions customisation requests and negotiates payment terms instead of accepting them.
This requires transparency on the figures, which stops some companies. The usual objection : “we do not want to share our margins with the sales team”. The alternative is to work on an internal index rather than the real margin, which preserves confidentiality while keeping the steering effect. The available mechanisms, including the collective bonus framed by collective bargaining agreement no. 90, are detailed in our article on variable pay for a Key Account Manager.
When a large account becomes an organisation of its own
Beyond a certain threshold, a major account stops being managed by one person and becomes a team : an account lead, a technical reference, a logistics contact, sometimes a dedicated controller. That shift deserves to be decided rather than endured. It typically happens when the client moves from a single buyer to a category-based purchasing organisation, or when it rolls the agreement out internationally.
The account owner then becomes the coordinator of a team they do not manage, which moves the required profile again, towards facilitation and arbitration skills. Companies that anticipate this hire someone capable of living through it from the start ; those that do not part company with their best salesperson eighteen months later, having failed to notice the job had changed underneath them.
The discount that never gets discussed
There is one concession that escapes almost every reporting system : the free work. Extra specification meetings, a proof of concept nobody invoiced, an urgent delivery absorbed by operations, a customisation delivered as a gesture of goodwill. Individually each is small. Cumulatively, on a strategic account, they routinely exceed the discount that was fought over line by line in the annual negotiation.
Making that visible does not require a new tool. It requires the account owner to log what was given outside the contract, and management to look at it once a quarter. The point is not to stop giving – flexibility is often what wins the renewal – but to give deliberately, and to trade it for something. A concession recorded is a concession that can be converted later.
Management’s role in defending margin
No salesperson defends a price position alone. When the buyer threatens to go to the competition three weeks before year-end close, the decision to hold or concede always escalates. If management systematically concedes at that moment, the salesperson learns in one season that firmness achieves nothing, and abandons it.
Sales leadership that genuinely protects margin does three things : it sets a floor per account in advance, it prepares non-price counterparts to trade against a concession, and it accepts losing a deal from time to time. That last condition is the hardest, and it is what separates a pricing policy from a speech about pricing. The ability to hold that line is among the criteria we examine when recruiting a sales manager or a Head of Sales.
Three decisions to take before hiring
One last point deserves to be stated plainly. Defending margin sometimes means accepting the loss of an account that has become structurally unprofitable, or deliberately reducing its scope. That decision belongs to management, not to the salesperson, but it has to be taken with them : nobody knows better which part of the volume could be replaced and which could not. A company that has never considered the possibility negotiates from weakness every year, and its buyers know it.
- Measure the real profitability of your top five accounts, cost to serve and payment terms included. Without that baseline, no margin objective means anything.
- Decide what the account owner can concede alone, and above what threshold the decision escalates. A clear delegation framework beats permanent internal negotiation.
- Write the mandate in terms of profitability before writing the job description. The profile follows from the mandate, never the reverse.
These three decisions explain why we spend time on the brief before sourcing. A mandate expressed in revenue attracts volume profiles ; a mandate expressed in profitability and account construction attracts different profiles, fewer in number and considerably harder to approach. The corresponding skills are detailed in our article on the skills required for long, complex sales cycles.
Seen from that angle, the opening question changes in nature. It is no longer what a Key Account Manager costs, but what it costs not to have the right one on your three most important accounts.
