White space from the client side.
I look for business needs an existing client has that your current scope does not cover. The gap may have been missed originally or created later as the client business changed.
An empty box in a service matrix is not evidence of demand.
Traditional account white space can map what the client does not yet buy from you. ProperBizFix asks a different first question: what does this client business require now that the current relationship does not cover?
I build a lightweight business and operating snapshot around the part of the client relevant to your relationship.
Where later change matters, I trace its likely consequence. Where the gap appears older, I test whether the need was simply outside the original scope.
The conclusion is allowed to be negative.
Published evidence, supplied account facts, analytical inference and open questions stay separate. The analysis may find relevant white space, retention risk, work outside your capability or no justified action.
Have one existing client in mind?
Send the company, what you currently provide and the relationship context that matters.
