Most of the time, a business searching for Enterprise support has a working copy of the software and a set of numbers it can no longer trust. That is not a support problem — it is a bookkeeping problem wearing a support problem's clothes.
A file that reconciles does not need support; it needs a bookkeeper who kept it that way. When inventory won't tie, when the balance sheet is out, when reports contradict each other, or when the prior year's totals shifted for no clear reason, no amount of reinstalling or calling about the software will fix it, because the software is not broken — the entries underneath are. This is the single most useful thing we can tell an Enterprise user: reconciliation, not reinstallation, is the cure for numbers you don't trust. If the free review shows your problem is bookkeeping, a cleanup resolves it; if it shows the problem is genuinely the product, we point you to Intuit and charge you nothing for the answer.
