Choose a relevant comparison
Product use, business scale and working practices matter. Comparing a small contractor with a large distributor may reveal a difference unrelated to sales potential.
Check the period as well. No purchase in one month could reflect seasonality or an earlier large order rather than lack of awareness of the range.
Turn the data into a question
Establish what the conversation should clarify. Does the customer perform work requiring the category? Do they use a different solution? Are availability, specifications or commercial terms important?
These questions test the need. Not every missing purchase should become an opportunity. Sometimes the correct conclusion is that part of the range does not fit the customer.
Record the conclusion and next step
Where a need exists, connect it with the relevant contact, proposal scope and action date. Where it does not, retain the reason so another salesperson does not repeat the same conversation.
For a sales manager, this directs attention towards justified opportunities. CRM combines purchase history, meeting information and customer segments. The comparison suggests a conversation; its outcome determines whether an offer makes sense.
