Quick Answer
How do you add a signature field to a form or survey?
Create a Signature custom field in Settings → Custom Fields, choose the folder or group where it should be stored, then open the form or survey Builder and drag the Signature field into the layout.
Collecting Verified Signatures Inside Your Forms
Some processes require more than a standard form submission. You may also need a signed agreement, authorization, or approval.
Signature fields allow users to sign directly inside a form or survey, creating a signature record connected to the submission.
Without a built-in signature field, you may need to rely on external tools or additional manual follow-up.
This guide shows you how to create, add, and manage Signature custom fields inside BizStackPro forms and surveys.
Signature Fields at a Glance
Before You Begin
Decide which folder or custom-field group you want to use for the Signature field so stored signatures remain easy to locate later.
What the Signature Field Does
The Signature custom field lets a user sign directly inside a form or survey. When the form is submitted, BizStackPro stores the signature in the contact record and adds verification details that can be used to validate authenticity.
Collect Signatures
Capture agreements and approvals digitally through forms and surveys.
Verification
Store a timestamp and encrypted hash with the signature submission for authenticity verification.
Stored With the Contact
Save signatures inside the contact record under the selected custom-field folder or group.
Organized Tracking
Use folders or groups to keep multiple signature fields easier to find.
Step 1: Create the Signature Custom Field
Open Custom Fields
Go to Settings → Custom Fields.
Add a Field
Click Add Field or + Add Field.
Choose Signature
Select Signature and click Next.
Choose the Storage Folder
Select the folder or group where you want the signature field stored.
Save the Field
Click Save.
Keep signatures organized
A folder such as Signatures or Client Agreements can make related signature fields easier to find in the contact record.
Step 2: Add the Signature Field to a Form or Survey
Open the Builder
Go to Sites → Forms or Surveys and open the Builder.
Open or Create the Form or Survey
Create a new item or click Edit on an existing form or survey.
Locate Custom Fields
Find Custom Fields in the left panel.
Add the Signature Field
Select your Signature field and drag it into the form or survey layout.
Rename the Label if Needed
You can rename the visible label, for example, “Sign Here”.
Save and Preview
Click Save, then Preview the form or survey to test the signing experience.
Authenticity, Validation, and Exports
Timestamp
Each signature submission includes a timestamp.
Encrypted Hash
An encrypted hash is generated with the signature submission for verification.
Submission Record
The verification details are stored with the submission for traceability.
PDF Exports
Signature and verification details can be included when submissions are exported to PDF.
Pair signatures with consent when appropriate
The original setup recommends pairing the Signature field with a checkbox confirming that the user agrees to your terms, with the terms text linked for reference.
Step 3: Find Stored Signatures in Contact Records
Open the Contact
Go to Contacts and open the contact record.
Find the Custom Field Folder
Look under the custom-field folder or group you assigned to the Signature field, such as Signatures.
Open the Signature Entry
Open the signature entry to view the stored value and related details.
Multiple signatures
If you collect multiple signatures from the same contact, such as contracts, waivers, or approvals, a dedicated folder can make those entries easier to track.
