Account portfolio management is the process of deciding how to allocate attention and resources across customer accounts. Here, “portfolio” means a set of business customers, not financial investments. The objective is to serve customers well while managing concentration, cost and growth opportunities.
A budget recommendation needs credible response estimates, consistent value assumptions and feasible constraints. The marketing budget decisions learning path connects this idea to the assumptions, practical checks and next steps.
To work through the connected decisions, read B2B MMM: model pipeline without confusing sales-cycle lag and SaaS MMM: connect trial acquisition to retained value.
Use more than revenue to rank accounts
A high-revenue account may require expensive support, custom work or unusually generous payment terms. Build a scorecard with revenue, contribution, service cost, renewal timing, relationship health and credible expansion potential. Keep observed facts separate from the account team’s forecasts.
Also review concentration. If one customer supplies a large share of contribution, losing that account changes the business’s risk even when the relationship appears healthy. The response may be better service continuity and a broader customer base, rather than simply selling more to the same customer.
Turn segmentation into a service decision
For a fictional software supplier, account A pays £100,000 annually but costs £70,000 to serve; account B pays £70,000 and costs £25,000. Before shared overhead, B contributes £45,000 against A’s £30,000. Revenue ranking alone would miss the difference.
Do not use that calculation as a reason to neglect account A. Investigate why its service cost is high and whether a better implementation, clearer scope or different package could improve the outcome for both sides.
Write an account plan that can be reviewed
- State the customer’s current objective and the evidence behind it.
- Map decision-makers, users and operational dependencies.
- Identify one retention risk or expansion hypothesis.
- Assign a concrete action, owner, date and observable success condition.
“Strengthen the relationship” is too vague. “Run a workflow review with the operations lead before renewal and confirm whether the unused integration removes a documented bottleneck” is actionable.
Evaluate interventions without circular reasoning
Teams often give the most attention to accounts already expected to grow, then attribute that growth to the attention. Where practical, compare similar accounts or phase an intervention across eligible customers. Record selection criteria before the programme begins.
The causal inference guide explains this selection problem. For resource decisions, use the same discipline as marketing budget allocation: define the objective, recognise constraints and review the next unit of effort rather than historical averages alone.
