SignContract for WooCommerce

Customer approval for custom and personalised WooCommerce orders

SignContract for WooCommerce helps merchants who sell custom, personalised, or made-to-order products collect signed customer approval before production begins.

If your business requires customers to review and approve order details, artwork, proofs, specifications, terms, or documents before you start working, this plugin automates that process inside WooCommerce.

Who the plugin is for

This plugin is built for merchants who need documented proof that a customer has reviewed and approved order details. Common industries include:

• Printing shops — send the final artwork proof for approval before sending jobs to press.
• Embroidery businesses — confirm the logo, placement, colours, and garment details before stitching.
• Personalised clothing stores — confirm names, numbers, sizes, and designs before production.
• Engravers — confirm the exact text, spelling, font, and layout before engraving.
• Signs and banners companies — confirm dimensions, materials, artwork, and installation details.
• Custom packaging suppliers — confirm the dieline, branding, dimensions, and print design.
• Invitation and stationery businesses — confirm names, dates, wording, colours, and layout.
• Promotional product sellers — confirm branding, quantities, colours, and product specifications.

How the approval workflow works

1. Assign an approval template to a product or category. The template contains the document or agreement the customer must review.
2. Customer places an order. WooCommerce automatically sends a signing link by email and shows it on the order page.
3. Customer reviews and signs. The customer opens the link, reviews the document, and approves by drawing, typing, or uploading a signature.
4. You get signed approval. The signed document and approval record are stored and linked to the WooCommerce order for your records.

Why merchants use this plugin

• Reduce misunderstandings — customers confirm artwork, spelling, colours, sizes, measurements, layouts, and production details before you start.
• Fewer remakes — clear approval records mean less back-and-forth when details are questioned.
• Fewer disputes and chargebacks — a signed approval linked to the order documents what the customer agreed to.
• Faster production — no waiting for email replies or phone confirmations. The approval link does the work.
• Professional process — customers receive a clear, branded approval experience.

The plugin connects to SignContract servers to create approval sessions, process documents, store signed files, and return status and verification data.

The plugin does not provide a complete local signing service by itself. Approval sessions, document processing, signed document storage, verification data, account usage, and subscription information are provided by SignContract.

External services

This plugin connects to the SignContract service at https://signcontract.app and https://api.signcontract.app/api. The service is provided by SignContract / Tengo International GmbH.

The SignContract service is required for this plugin to create signing sessions, process agreement documents and templates, generate signing links, store signed documents according to the merchant’s plan, provide verification metadata, return account/subscription/usage status, and send webhook updates back to WooCommerce.

Privacy and data retention

Signed documents and metadata may be stored by SignContract according to the merchant’s selected plan and retention or download availability period. Signing link expiry controls how long a pending signing link remains valid. It is separate from signed PDF download availability or retention after signing.

Merchants are responsible for informing their customers that order and signing data may be processed by SignContract and for updating their store privacy policy accordingly.

Suggested privacy policy text:

When a product or order requires document approval or electronic signature, we may send order details, customer contact information, and the relevant agreement document to SignContract to create and process a signing session. SignContract may store signed documents and verification metadata according to our selected plan and retention settings.

Security

• Signing links are tokenized and expire.
• Expired signing links show an expired-link message.
• Webhooks are signed and verified using HMAC signatures created with a generated webhook secret shared server-to-server with SignContract.
• The API key is used for authenticated API requests from WooCommerce to SignContract.
• The generated webhook secret is used only to verify webhook callbacks from SignContract to WooCommerce.
• API keys and webhook secrets are stored in WordPress options.
• Technical server-to-server settings are hidden in production where applicable.

Developer Notes
