Customer expansion ABM helps your account team investigate and develop a specific additional opportunity. Start with the new problem and the people responsible for it. Use relevant evidence from existing work, check how the new group sees your business and agree a next step before building a wider campaign.
You deliver good work for one team inside a customer account. Your account owner can see an opportunity in another division, but that buying group knows you for the service you already provide, if it knows you at all. The existing relationship gives you a starting point; it doesn’t settle the new group’s decision.
Your marketing task is to understand the new use case and give those people a reason to consider a different capability. That may require different evidence, different relationships and a clearer explanation of what transfers from the work you’ve already done.
Test whether your existing proof transfers to the new opportunity
An expansion brief should state what the existing relationship actually proves. Reliable delivery for one department may demonstrate responsiveness and knowledge of its process. It may not establish capability at a different scale, compatibility with another division’s systems or credibility with a new approver.
Use a transfer review with four entries: the original work, the new requirement, the relevant similarity and the unresolved difference. For example, a successful regional service can support a discussion about delivery discipline, while a group-wide proposal still needs evidence about governance and integration. Try this worked example against your own account; its assumptions will need checking with the people involved.
The account-based experience methodology explains how research into people, culture and current perceptions shapes the approach. In expansion, that work should test whether the new group recognises the capability required for its own problem. More visibility is unlikely to resolve a concern about delivery risk unless the campaign answers that concern.
Choose the smallest useful next commitment: clarification of requirements, an introduction to a relevant function or an evaluation discussion. Record what that commitment establishes and what remains unproven. Entry into an evaluation or procurement process is progress; it should not be described as a completed expansion sale.
Establish why the customer would buy something more
Define the problem, affected business area and plausible value of addressing it. Separate this from the current contract. A successful relationship in one area doesn’t establish a need elsewhere.
Ask what evidence would make the expansion hypothesis credible. It might be a stated priority, an operational change, a request from the customer or a problem observed during delivery. Keep inferred opportunities clearly labelled until validated.
Include the option that there is no suitable expansion at present. A useful account plan can protect the relationship by avoiding an irrelevant proposal.
Map the relationship you have and the one you need
| Account-plan element | Current-state question | Expansion question |
|---|---|---|
| Problem | What do we currently help with? | What different issue may need attention? |
| Stakeholders | Who knows and works with us? | Who owns or influences the new decision? |
| Perception | What capability are we known for? | What would the new group need to believe? |
| Evidence | What results or delivery experience can be supported? | Which evidence is relevant to the new use case? |
| Access | Which relationships are active? | Who can appropriately introduce the new discussion? |
| Milestone | What is already agreed? | What specific movement would validate the plan? |
Use this worksheet with your account team to distinguish what you know from the current relationship and what still needs investigating. Familiarity with the customer can make the gaps easy to overlook.
Find out how the new buying group sees you
Speak with the account team and, where appropriate, customer stakeholders. Ask what the new group knows about the organisation, what it associates you with and what would make it hesitant to consider you.
Find out what’s preventing consideration before commissioning a campaign. The new group may question your delivery scale, prefer an incumbent or have a different approval process. If you assume every barrier is awareness, you can spend the budget making a familiar name more visible without answering the actual concern.
Edelman and LinkedIn’s 2025 thought-leadership study considers how content can influence less-visible decision-makers. It provides context for building useful evidence beyond the existing sponsor, not a guarantee that thought leadership will unlock an expansion.
If the perception gap concerns capability, show relevant work and explain the method. If it concerns risk, address transition, governance and accountability. If the use case itself is unconfirmed, prioritise a discovery conversation over a persuasive campaign.
When an existing customer knows only one part of your business
Imagine a supplier that helps a customer maintain a regional reporting process. The customer is now considering a wider operational standardisation programme. The supplier believes its broader expertise may be relevant, but the transformation team knows it only as a support provider.
The account plan starts by validating the transformation objective and identifying who owns it. The existing operational contact may offer an introduction, but isn’t assumed to control the wider decision.
The proposed next step is a workshop comparing transition options and implementation risks. Evidence from the current relationship is used only where relevant, with permission and appropriate confidentiality. The workshop’s purpose is to test the use case and decision criteria, not to presume a purchase.
If the transformation team agrees to an evaluation, that is a meaningful milestone. It remains separate from a commercial win and should be reported as such.
Give the new buying group relevant evidence
An existing success story may need explanation to travel. State what was delivered, under what conditions and what can reasonably transfer to the new problem. Avoid implying that success in one division guarantees the same result elsewhere.
Prepare evidence for the different responsibilities involved. An operational sponsor may need a practical plan. A technical reviewer may need integration detail. A commercial approver may need cost assumptions and delivery accountability.
LinkedIn and Bain’s enterprise buying-group research draws attention to risk and process reviewers. In expansion planning, check whether the existing relationship reaches those functions or only the current users.
Keep unsupported numerical outcomes out of the campaign. If the available case evidence establishes a milestone but not measured financial impact, explain the milestone and the mechanism honestly.
Coordinate customer success, sales and marketing
Assign one owner for the expansion plan and clarify each team’s role. Delivery colleagues may know the operating reality. Sales may manage the commercial process. Marketing may develop the evidence and account experience.
Agree when and how to approach new stakeholders so the customer doesn’t receive disconnected messages. Record current commitments and relationship sensitivities before introducing a new proposition.
Protect the existing service relationship. Expansion activity shouldn’t distract from unresolved delivery issues or imply that normal support depends on buying more. If current performance is a concern, address that evidence directly in the account plan.
Check whether existing proof is transferable
For each proposed proof point, compare the original delivery conditions with the new use case. Consider the business process, scale, geography, stakeholders and dependencies. State which parts are similar and which require further validation.
A successful regional project can demonstrate a method and a working relationship. A global rollout raises additional questions about capacity, governance and integration. Name those differences when presenting the proof, so your strongest reference starts a credible discussion rather than carrying a claim it can’t support.
Use the existing customer relationship to learn, not to skip qualification. Ask which aspects of the current service the new group knows about and whether that experience matters to its decision. A positive reference from one function may be helpful but insufficient for another function’s risk assessment.
Where internal sharing of customer information is sensitive, agree the appropriate evidence and presentation route. An anonymised method example may be more suitable than a detailed account-specific result. The campaign shouldn’t depend on disclosing material the team isn’t authorised to use.
Track the new opportunity separately
Separate the proposed expansion’s scope, owner, stage and expected timing from the existing contract. This makes it possible to assess whether the new initiative has progressed and what resources it has consumed.
Record what was already happening before the expansion programme began. If the new group was already evaluating your proposal, marketing’s job may be to resolve a specific concern. If it had never considered your capability, the job is different. That starting point matters when you judge progress.
Agree the conditions for handing activity from marketing to the account team and back again. A useful workshop may reveal a need for more technical evidence rather than an immediate proposal. A delayed initiative may return to education with a specific review trigger.
Finally, keep renewal and expansion risks visible together without combining their outcomes. An expansion campaign shouldn’t distract from commitments that sustain the existing relationship. The account owner needs a complete view of priorities, while the measurement still distinguishes what the new programme actually achieved.
Measure a sequence of validated steps
Track confirmation of the use case, access to relevant functions, agreement on evaluation criteria and formal next actions. These measures describe progression without pretending that every interaction creates revenue.
Keep the expansion opportunity separate from the current contract in reporting. Otherwise, existing revenue can make the new programme appear successful before it has produced a new commercial result.
Review the plan when the account’s priorities change. A paused initiative, new owner or altered operating structure may require a different response. The objective is a relevant account relationship, not activity against an outdated hypothesis.
