As has been stated above, I also use Quick Books as my
accountancy program.
As an aside, Quick Books (down under) are changing their name, probably doing the same over there.
From their site...........
Reckon Accounts, business and personal finance solutions
Previously known as QuickBooks & Quicken
I also use one of their other programs called
Customer Manager.

Yes, I know, it's an Aussie address, just Google it and find your own over there.
I have been using this for a decade or so to track my customers & suppliers.
I'm happy with it.
PS::: Just saw Brent's post.
I don't run any on-line programs, nor do I run "Cloud" programs.
I still get my discs as required from Quicken.
Due to the many hills and valleys around my town, coupled with poor reception, "Cloud" will not work in many areas.
