Supporting the internal promotion of a sales manager in a communications agency

Promoting a strong salesperson to lead the team rewards past results while giving them a different job, in which success depends on collective performance and the ability to balance interests that sometimes conflict.

• Individual selling still matters, but it can no longer consume most of their time.
• Management adds responsibility for recruitment, coaching, forecasting and account allocation.
• In an agency, a signed contract is only a success if delivery capacity, quality and margin allow the work to be fulfilled properly.
• The promotion also changes relationships with former peers, including when the new manager must challenge performance, assess people or redistribute opportunities.

1. Check that the promotion addresses the right need

Before choosing the person, the leadership team should describe the problem the role must solve and establish whether the candidate genuinely wants to manage, because excellence in selling demonstrates neither the desire nor the ability to help others improve.

• Expected mission: clarify whether the priority is to structure prospecting, improve forecast reliability, grow existing accounts, recruit or bring sales and delivery closer together.
• Observable capabilities: look for examples of teaching, collaboration, difficult decisions and commercial judgement on a project, beyond the candidate’s personal revenue.
• Real motivation: discuss the time spent on one-to-ones, conflict and follow-up, as well as the possible reduction in individual commission.
• Gap to close: turn identified needs into supported work situations; generic leadership training cannot substitute for practising the role.

2. Give the new manager a clear mandate with former peers

The announcement should make the new mandate understandable to the team, because a title without defined authority leaves the manager caught between leaders expecting results and colleagues who continue to negotiate every decision.

• Independent decisions: state what they can decide about accounts, discounts, priorities, targets and day-to-day organisation.
• Shared decisions: identify the matters that remain with agency leadership or delivery leads, particularly recruitment, unusual pricing and risky commitments.
• Fairness rules: explain how leads, major accounts and commission will be allocated so that the promotion does not look like a route to keeping the best opportunities.
• Proportionate communication: explain the reasons and responsibilities internally; make an external announcement only when it conveys useful information to clients and partners.

3. Connect sales objectives to the agency’s economics

The sales manager should oversee a complete system rather than a single sales total, using indicators that connect the demand created with the resources required to deliver it and the value the agency actually retains.

• Development: track pipeline quality, movement between stages, account concentration and forecast reliability.
• Project economics: compare expected and actual margin, discounts, scope overruns and the cost of pre-sales work.
• Delivery capacity: test promised dates and skills against available workload before approving a major proposal.
• Relationship quality: monitor reasons for losses, renewals and gaps between the sales promise and the client’s experience.
• Management: assess team development, the quality of reviews and the quality of decisions as well, without making the manager’s personal sales the main criterion.

4. Build the first 90 days around real situations

A three-phase transition gives the new manager time to observe, decide and then consolidate, while giving agency leadership checkpoints close enough together to correct a difficulty before it becomes established practice.

• Days 1–30 — understand: map accounts, pipeline, delivery workload, roles and sources of friction; join client meetings and develop a diagnosis to discuss with the team.
• Days 31–60 — practise: lead sales reviews, make decisions on selected opportunities, hold the first one-to-ones and document sensitive choices.
• Days 61–90 — stabilise: propose changes to portfolios, routines or objectives, then state what will continue, stop or be measured differently.
• Throughout the transition: hold a weekly conversation with an agency leader or mentor who helps the manager reason without taking their decisions back from them.

5. Address relationships with former peers directly

The move from colleague to manager becomes credible when the same rules apply to everyone and disagreements are handled through the work itself, without asking the new manager to disown the relationships they built before the promotion.

• Common framework: set one-to-ones, opportunity-allocation criteria and a review method that apply to every member of the team.
• Explicit conversation: ask what each person expects from the manager, then explain what changes in the relationship and what now falls within the manager’s authority.
• Concrete disagreement: when someone resists, return to a case, rule or observable behaviour rather than interpreting that person’s loyalty.
• Useful escalation: involve agency leadership if the mandate is repeatedly challenged or a conflict of interest exceeds the authority given to the manager.

6. Confirm the promotion using shared evidence

At the end of the transition period, the decision should draw on several consistent forms of evidence and lead to specific adjustments, because a general impression or one quarter’s results cannot properly assess a move into management.

• Results: compare pipeline, sales, margin and forecast quality with the agreed objectives, taking the starting point into account.
• Decisions: examine a small number of documented judgements, their assumptions and their effects on clients, the team and delivery.
• Team: gather focused feedback from salespeople, delivery staff and leaders on observable behaviour, then share the themes without turning the exercise into a popularity vote.
• Next step: confirm the scope, remove a responsibility that was introduced too soon or extend support with an explicit date and criteria.
• Recognition: align pay with the collective role and expected economic outcomes so that the manager is not encouraged to retain every account they ought to hand over.

The success of an internal promotion shows less in the quality of the announcement than in the coherence of what follows, from the mandate granted to the evidence used to confirm the person in the role.

• The manager knows what they may decide and which criteria should guide them.
• The team understands how opportunities, objectives and disagreements will be handled.
• Agency leadership supports the mandate without routinely taking control back.
• The agency connects sales growth with delivery capacity and margin.
