About Mailform

The easiest way to snail mail your FreshBooks invoices. Mailform was built to make sending mail easier. The old school way requires a printer, stamps and envelopes. Ran out of stamps? Now you have to go to the store or even worse the post office. The process is clunky, time consuming, and wasteful. Mailform does all of this in about 5 minutes…2 if you’re really trying hard!

Mailform retrieves customer names, addresses and invoices directly from your FreshBooks account, prints them, stuffs the envelopes, stamps them and hands them over to the USPS for you.

How it works with FreshBooks

The integration allows a customer to see all unpaid invoices within the selected company. You can then pick which invoices to mail via USPS First Class mail. Mailform will handle printing out the invoices, stuffing them in an envelope and handing over the envelopes to the USPS for delivery. Mailform also marks the original invoice as SENT in FreshBooks once the invoice is printed. 

Note: This app requires in-app purchasing to send mail.
