    How Flow Technology works

    Combine multiple business transactions into one workflow. Send a document for review and esignature and include your payment portal in one Flow email and text payment request.

    Collect payments and esignatures on contracts, legal agreements, rental agreements, insurance premiums, sales orders, and estimates.

    Consumers sign and then enter their own private payment information on a secure form. Your staff never sees, hears, or touches sensitive payment data.
