Very happy
just wanted to say how happy I am with your software. I created an account and managed to file to HMRC and Companies house in under an hour. Have tried other online solutions, but no others come any where close in terms of ease of use
declaration Mary Rackham
Small Company IXBRL Accounts
Filed for a small company so the accounts were more complex than Micro. The simple and intuitive input forms for the CT600 and accounts guided me through the process. Normally its an end of year task I dread, now I have found you not any longer!
declaration Peter Jeffery

The support you provided me with was fantastic, I found the online chat especially useful and so responsive. I don't know who I was chatting to but they were patient and explained exactly what I needed to do
