Overview
The eXtendFiles Signature
Uploader enables mobile users to capture touchscreen digital signatures
(using a finger or stylus) and attach them directly to NetSuite records as
eXtendFiles attachments.
You can add the signature
uploader to Create, Update, or View functions across
standard and custom NetSuite record types (such as Sales Orders, Item
Fulfillments, Purchase Orders, and Work Orders).

Frequently Asked Questions (FAQs)
Q: Can users capture
signatures on eXtendMobile Web?
A: While administrators can configure forms on eXtendMobile Web, digital signature capture requires touchscreen
drawing hardware and is exclusively executed within the eXtendMobile Mobile App
(iOS and Android).
Q: Can signers use a stylus
or Apple Pencil?
A: Yes. The signature canvas
supports both finger touch and passive or active styluses (Apple Pencil,
Samsung S-Pen, etc.).
Q: What image format is
saved?
A: Signatures are exported as
lossless PNG images with a transparent background and stored directly in your
connected cloud storage.
Q: What happens if a user
submits a form without capturing a signature?
A: If the Signature Uploader
field is present on a Create or Update form, eXtendMobile validates that the
signature URL and filename are populated. If left blank, the app will prompt
the user to complete all mandatory fields.
