Adjacent-service cross-sell

The pattern

The hypothesis is that two complementary services address needs held by the same customer and could be delivered through a coordinated relationship. The proposed mechanism might be easier procurement, fewer handoffs or a broader service scope. It needs a specific buyer and use case. Two companies serving the same industry may sell to different decision-makers, operate on different budgets or require separate procurement and qualification processes.

Begin with the customer's work rather than the seller's catalogue. Ask when the additional need arises, who authorises it and whether the existing provider has the competence and permission to address it. Public research can establish service descriptions and stated customer segments. It cannot establish actual shared accounts, willingness to buy an additional service or contractual access to customer data. Those questions require consented commercial diligence and suitable delivery expertise.

Where to investigate it

These playbooks provide operating contexts in which to test the mechanism. Sector membership alone does not establish a match.

• HVAC services
• Plumbing services
• Electrical contracting
• Managed IT services
• Cybersecurity services
• Specialty distribution

Hypotheses to test

• A defined customer has both needs and can consider the combined offer through a workable purchasing process. A shared industry label should not substitute for a buyer-level explanation.
• The services fit operationally and professionally. Required licences, technical skills, independence obligations and response capacity must be maintained when responsibility spans a broader offering.
• The customer would value coordination enough to consider an additional supplier relationship. Demand should be tested directly rather than inferred from the convenience of the seller's organisation chart.

Public evidence that supports further investigation

• Company service pages describe complementary tasks within the same customer workflow. Record the tasks and buying context rather than treating a long list of capabilities as evidence of cross-selling.
• Public procurement specifications combine the relevant services in one scope. This demonstrates a possible buying configuration without establishing that the target has access to those buyers.
• Published support or delivery materials explain how responsibilities are coordinated across service lines. These can support a capability question while leaving actual customer adoption and satisfaction unverified.

Evidence that could kill the hypothesis

• The apparent adjacent service is purchased by a different buyer under incompatible procurement arrangements. That contradicts a thesis premised on using the same commercial relationship.
• The added work requires capabilities or permissions that the proposed organisation cannot provide. A referral relationship may be feasible, but it would be a different operating mechanism.
• A verified customer or channel restriction excludes the proposed combined offer. Customer choice, independence requirements or supplier terms can defeat a commercially appealing service adjacency.

Common failure modes to examine

• Sales teams offer work before delivery teams can support it. A broader promise can damage the original relationship if service accountability and escalation are unclear.
• A concentrated account base resists a bundled supplier or insists on separate competitive procurement. Customer access does not create an entitlement to additional spend.
• Integration combines customer records without understanding consent, confidentiality and contractual restrictions. Relationship knowledge and permission to reuse information are separate diligence questions.

Typed screening questions

What changes in origination

Build the universe around a named customer workflow and adjacent task. Capture buyer roles, required permissions and delivery responsibility as separate criteria. A company can be a useful referral partner without being an acquisition fit, so do not collapse every commercial adjacency into the same target cohort.

Use early conversations to test customer need and delivery fit, without promising access to existing accounts. Later diligence should examine account overlap, procurement constraints and service capacity with appropriate permissions. The thesis should survive a clear explanation of who benefits and how the work would actually be performed.

Apply it to a target list

Turn the hypothesis into client-specific screening questions, with accepted answers and an evidence requirement for each. Triage resolves identity before research is paid for, removes duplicates and wrong-site records, and asks disqualifying questions first. Scout collects typed values from a fixed list, each quoting a retained page verbatim. Audit re-reads with every fetch tool denied, settles contradictions, strikes unquotable findings and leaves gaps visibly open. Review the evidence standards before interpreting a shortlist.

Bring a list or ask Docket to build one. Use the self-serve platform or a managed engagementwith a dedicated analyst and weekly criteria review. Each client's docket is a separate database; the client owns its data and can export CSV or Excel at any time. Outreach is optional: approve the messaging and each target before email, LinkedIn or phone contact. The first ten targets are researched free.
