PactCanvas Sign & Proof helps merchants collect customer acceptance for custom orders and B2B terms before an order is placed. Assign agreements to products, eligible customers, or the full checkout. Customers review the current terms, complete required acknowledgements, and sign. The app then links signed agreement records and PDF evidence to the order for later review. Merchants control templates, publishing, assignments, and retention from the Shopify admin.

• Collect typed or drawn signatures for custom-order and B2B terms
• Present the agreement based on products and customer eligibility.
• Require agreement acceptance before applicable orders can be placed.
• Keep signed records and PDF evidence linked to each resulting order.
• Publish updated terms without changing previously signed records.
