I'm also a QB user of 10 years and I am really happy with it. My question was really if there was anything I should be aware of for a retail business that QB would not be suitable for, as I haven't used it for retail previously.
I spoke with Axonware this morning and they are only able to import lists to Quickbooks i.e. customer, supplier etc not the actual data. As the bookkeeper had saved the TAS files for most of the FY in a newer version he would have no access to data already entered for 85% of the financial year as it was not backwards compatible with the old version of the software he had installed.
I agree on the support also as I have not needed to purchase support for QB in my ten years of using it. As I already have QB, I may look at transferring the data to that for the new FY as TAS is already giving me a headache; it's definitely not as user friendly as QB is.
