Our friends at Formstack have built a fantastic integration that allows you to collect information from contacts on the web and pass it through to Batchbook. For more details on the power of Formstack forms check out their Formstack Resource Center.
The Formstack Integration pushes contact information including name, email, phone, address, etc., along with tags and Custom Field information from a chosen Custom Field. At this time, the integration allows use of one Custom Field.
