Today we switched over our Adwords account administration from the marketing firm we had been using to in-house. I'm finding out now that they had been using postpay billing, which has a maximum threshold of $500.

I want to change to a prepay option but they are telling me I have to close the account and restart it in order to achieve this, but isn't that a bad idea? Won't I lose account history and therefore quality score if I do this?
