Also, Snapdocs does not count your manually added jobs in the number of signings you've performed. If you add a job and go to My Account and look at View Public Profile, you will see the difference in the number of jobs the public can see vs. the number on your dashboard.
I use Notary Gadget which tracks expenses, number of notarial acts, jobs and pay per company, etc. and provides an invoice that is automatically populated based on the signing information you've put in. Then all you have to do is click send and it will be emailed to the vendor. It also generates reports for you to print or email to your accountant/bookkeeper for tax purposes. It's only $9.95/mo, $99.95/yr or $249.95/3 yrs. which is a business expense.
