My understanding is that the quarterly reports to HMRC under MTD will just be a few line entries.
Our preference for client bookkeeping for the vast majority of our clients has always been VT. We do use QB online for some clients who prefer to use online bookkeeping but we find data input much easier with VT and really don't want to move away from this.
Is it likely to be acceptable under MTD (for those clients who will be required to report) to still do all the bookkeeping in VT and then just post totals to HMRC each quarter. If that doesn't work could you get away with entering totals from VT into QB on a periodic base and then submit to HMRC. Probably not but just wanted to throw it out there.
I am obviously no fan of the whole idea of MTD which I think is yet another pointless example of government meddling and running up unnecessary costs for business (just like RTI and Auto-enrloment)
Indeed don't really know what digital means (although apparently online bookkeeping is "digital" but spreadsheets are not). Have looked up dictionary definitions but this doesn't really offer much clarity. For me a digit is just a number in the way that one would say 1234 is a 4 digit number so don't see why spreadsheets (or VT) shouldn't quality.
