QB Issue Resolution:

No, an estimate is non posting, it does not affect the financials

However, you can not receive a prepayment against an estimate, it would have to be turned into an invoice when that prepayment is received.  Using a service item that is linked to a liability account will avoid the increase in income, until you use that item again as a negative number on the final invoice.
