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.

Returning customers may not remember whether they bought a product or which option they selected. BuyTrail adds their purchase history to product pages so they can confirm a previous order before buying again. Merchants can synchronize available order history and choose where the app block appears in their online store theme. Only the signed-in customer associated with an order can see its purchase details.

• Show purchase count and the latest purchase date on product pages.
• Display the option values selected in each customer’s latest purchase.
• Let signed-in customers open the related order from their account.
• Synchronize available order history and keep it current.
• Add the storefront block to product templates through the theme editor.
