Good billing/invoicing software?
 

So I can add some clients and just print out some invoices, select their profile and add some memos and whatever?

Anyone got suggestions?

QuickBooks for pure biz, or Quicken Home and Business if you want to mix it up with your personal finances.

Quickbooks or PeachTree

If just invoicing, statements, AR list etc ...:

If you need accounting ( balance sheets, loss/profit ) then Quickbooks.

quickboooks

Quicken or Quick Books
