invoices

[ariel del rio]

I have been looking for a book that will teach me how to
make invoices that will adjust to my needs. Also how to
transfer all the information contained on the invoices to
a data base so if I want to know how much Charlie owes me
I can find out right away, also how may of something I
have sold, etc.
I have looked in several places, and looked into tens of
books, some of them about 400 pages thick, and I have not
found anything, everything is about workbooks, charts and
graphics. The help that I find in Excel itself is too
confusing.
Can somebody help me?
Thanks
