Common worries

What do people worry about with free signing apps?

BoldSign answers the five questions people ask most before they trust a free signing app.

Is it a trial in disguise?

No. The Essential plan costs $0, it is not a trial, and you sign up without a credit card.

Will I run out after a few documents?

The allowance renews every month. The comparison below sets it against the other free plans.

Do my signers have to sign up?

No. Your signers open the email link and sign in a browser, with no app, account, or payment.

Will the signed copy hold up?

Every completed document comes with an audit trail of who signed, when, and from which IP address, and BoldSign adds no watermark.

So what is the catch?

No catch. Every limit of the free plan is listed in the limits section.
