You may wish to do this for several reasons. You might simply want a backup of your data held locally on your computer. You may want to perform some advanced reporting based on the proposals sent and their status - for example you could easily chart how many proposals are sent each month and what their current state is, providing you with a proposal conversion ratio. In addition if you are a manager you may want to track performance of your team by building a report on quotations sent out per consultant. There are huge numbers of reports and charts you could generate from this data which will provide meaningful management reporting.
