Why Retailers Need E-Signing Functionality

If you run a retail business—especially in B2B, high-ticket, regulated, or rental environments—you know how critical it is to collect signed agreements, waivers, or legal approvals before fulfillment. Without the right system in place, you're stuck dealing with delays, manual follow-ups, and avoidable errors. By adding e-signature functionality to your checkout, you allow your customers to sign instantly during checkout or order confirmation. This improves compliance, accelerates approvals, and reduces manual bottlenecks in the document signing process. Whether you need to finalize a B2B sales agreement, confirm a liability waiver, or authorize a custom service order, you can streamline everything using electronic signatures, digital certificates, and a verified signer's identity. It's faster, safer, and more reliable than handwritten signatures.

How It Works for Your Customers at Checkout

When your customer reaches checkout, they're prompted to sign digitally using their mouse, touchscreen, or mobile device. This sign-on-screen for eCommerce experience is built directly into your checkout flow—no redirects, no extra steps. The system captures the electronic signature at checkout, binds it to the order ID, and stores it securely in your CMS or CRM as part of your electronic records. You can automatically email the digital document to the customer or archive it. You control where and when the signature field appears:

Directly at checkout
Immediately after payment
Before a digital download is released
During account creation (for B2B onboarding)

The signing process leverages your customer's private key, validated by a trusted certificate authority, and uses their public key to ensure signature authenticity and verification. This level of security ensures every signature is legally binding, tied to a verified signer's identity, and compliant with regulations.

Platform Integration: Shopify, BigCommerce, Magento, and More!

This digital signature offer works with Shopify, BigCommerce, Magento, WooCommerce, VTEX, and custom carts. You can add the signature field via:

Checkout page (Shopify Plus / BigCommerce API)

Secure contract links sent after purchase

We support full e-signature integration for Shopify and BigCommerce without affecting your payment flow. Signed electronic records can be automatically linked to orders, organized by public key ID, timestamp, or customer profile.

E Signature Functionality Is Legally and Security-Compliant

All digital signatures are encrypted using secure public key infrastructure, paired with a private key and verified via a certificate authority. This ensures your signatures meet global legal standards like eIDAS, the ESIGN Act, and UETA. Documents include IP capture, timestamp, electronic sound (if applicable), device info, and full audit trails. Each digital certificate confirms that the signer’s identity is authentic and the electronic document hasn’t been altered. If your store deals with legal documents, financial documents, or regulated industries, using electronic signature software adds a layer of data security, trust, and accountability backed by a trust service provider.

What Are the Use Cases by Industry?

Common use cases for digital signatures in eCommerce include:

B2B supply agreements
Drop-ship authorization
Product warranties
Age verification for restricted items
Rental agreements for tools or equipment
Pre-order commitment forms
Delivery waivers and consent to terms

You can use this with any electronic form that requires customer acknowledgment. Whether you're finalizing legal documents or confirming order details, this solution simplifies the signing process.

CRM + Document Storage

Signed electronic documents can be auto-saved to your CRM (Salesforce, HubSpot, Zoho) or tied to the customer's order in your backend. Documents are searchable by customer, order ID, or digital certificate number. Everything is archived securely as electronic records, reducing paper waste, streamlining access, and simplifying future audits.
