You have partners. Somebody sends a sales figure at month end, usually a total, sometimes a list by party. The strong partners are known by name and the weak ones by a vague feeling. Between them sits a middle group nobody looks at closely, because there is no agreed way to look. When the year runs short, the response is a scheme, a discount or a push on the two partners who were already going to buy. Nothing about that is unusual. It is what happens when a channel grows faster than the routine used to run it.
Why it persists. Partner data is awkward. Primary sales sit in your accounting system, secondary sales sit with the partner, activity sits in a manager's head, and none of the three agree. A comparable view feels like a data project nobody has time to run. The partner is also a customer, so a hard performance conversation feels like a commercial risk. It is easier to keep the relationship warm and hope the number recovers. That instinct is understandable, and it lets a quiet decline run for a year.
If it stays unresolved. The channel keeps expanding by appointment rather than by productivity. You add partners because coverage looks thin, when the real problem is that the partners already appointed work at a fraction of what their territory holds. Cost of service rises, margin goes into schemes, and the network gets harder to fix each year, because nobody can prove which partners deserve investment.
