This is fabulous! I was using Nuance PDF Converter, which has worked fine for many years, but it couldn't handle a couple of the 2013 IRS forms...So I did them here. And it worked!

Great customer experience with this company. Very responsive to technical questions and billing service cared more about our satisfaction than most companies even though it wasn't to their direct bottom line advantage. Will use them again surely.

How do you process an invoice?
Typical Process Invoices can be sent via email, postal mail, fax, or EDI. Once an invoice arrives, the accounts payable clerk must ensure that the document is indeed an invoice. Then the clerk classifies and sorts the invoice into various categories (e.g., by vendor, by transaction type, or by department).
How often should invoice to customers be prepared?
If you choose to invoice semi-monthly, indicate two invoice days (like the 15th and 30th) and send invoices on those days only. A monthly invoicing system is the most common, but it's best practice to send the following month's invoice on the 10th or 15th of the current month.
Is there a time limit on invoicing?
There is no specific time limit set for invoices. The legal wording generally used is that an invoice must be issued within a “reasonable” amount of time. The definition of reasonable varies depending on the industry you are in, state and about any other circumstance you could think of.
