Cross-selling begins with permission to notice

An adviser working closely with a client will see problems outside the original scope. Some deserve attention. Others are merely adjacent to something the supplier would like to sell. The distinction should be examined before opening a new commercial conversation.

Describe the observation and its possible consequence, then ask whether the client wants to explore it. Do not present an unsolicited diagnosis as settled fact. You may be seeing only one part of the organisation.

Keep the existing engagement intact. A client should not feel that every discussion is being mined for another sale. Continue delivering the agreed work while separating any new investigation or proposal.

If another specialist is better suited, say so. The value of noticing a problem lies partly in helping the client find appropriate help. Automatically steering every issue into your own catalogue undermines the position of trusted adviser.

Timing matters. A newly discovered weakness may be important but poorly timed for action. Agree whether to address it now, record it for a later review or leave it alone. The client's capacity and priorities belong in that decision.

Cross-selling works best as a consequence of understanding the client, with a clear boundary between observation, diagnosis and commercial recommendation. It becomes less credible when the supplier treats access as an entitlement to expand the account.
