Proposal Invoice

Easy to use! You only need to enter in data 1 time, even as your document proceeds from being a Proposal to an Acknowledgement, then on to an Invoice , and finally becomes a Receipt.
Do virtually all your work on a single computer screen "form" - no switching back and forth between different windows.

If you've been wanting to get away from using pre-printed forms but haven't been able to find any reasonably priced software, this is the answer.
