I was just charged double what I paid for QB online last year, and invoice said I had a 50% "discount" last year, unbeknownst to me. Have others had this problem?

Your discounted price may be expired and you have to pay the regular price now. If you wish to keep the lower price, you will need another effort. Utilize a 3rd party tool to migrate your data between QBO accounts.

Once you are ready to proceed, open a NEW QBO account with the current discounted plan. You may get a discounted price for up to 6 months.
