Second, Bitrix24 website forms are already integrated with our free CRM, so you can start marketing to people who filled the form right away. Both email and telemarketing options are already built-in. Bitrix24 also offers quotes, invoices and online payments, which is useful when you create registration form for events that have a coverage fee (seminars, workshops, etc).
Third, fields and submissions are free and unlimited. We also give you free field rules (conditional logic) and post submit actions (redirects). Any type of form - contact, feedback, support, registration, online ordering, product selection, resume submission and so on.
