A client tells me they wish they had a feature we literally sell, and I just nod and say that's great. I never bring up the upgrade, never mention the bigger package, even when it's staring right at me. Money that's sitting there for the taking, and I walk right past it every time.
More people experience this than they realize.
You never mention the upgrade, so obvious chances to grow the account slip past you.
If this sounds familiar, the Library can help you find the bigger picture.
