Our bookkeeping is done on QuickBooks.
We have some highly customized forms and templates that we use for our invoicing and purchase orders among others.
We did a trial run at upgrading our current QB 2007 company files to QB 2010.
Since we use the multi-currency capabilities of QB, we needed to wait until the 2010 version became available as the earlier versions of the new code base did not support multi-currency.
So, the verdict?
We lose all of our custom forms and templates. As far as the data is concerned, we need to dig in a bit deeper yet to see if anything was broken in the process.
So, we will hold off a bit longer on the upgrade for our production bookkeeping until things slow down a little more and we have finished migrating our own SBS network to SBS 2008.
As a result, time needs to be budgeted for rebuilding those forms when upgrading from earlier versions of QuickBooks.
