This doesn't address the issue raised. Your colleague has stated that the FRS can't be used with the DRC. This is wrong, it can, but it appears your software is inadequate - it is not a question of raising it with HMRC, an accurate treatment and return should be provided in QB.

Considering your advertising stresses that small business owners can stop worrying about all their taxes because you are so great, I'd suggest this fails massively under trades descriptions.
