E-signatures are currently in beta. Enable them under Settings > Beta features before getting started.
E-signatures let you attach signed contracts to rentals. Author contracts as templates with Liquid, send them automatically when an order is placed, and collect signatures online or in person on Shopify POS.
Supercycle charges $0.75 per completed e-signature. A signature is counted when a customer signs a contract.
Key functionalities include:
  • Contract templates: Author HTML + CSS + Liquid templates for any rental contract you need.
  • Multiple contracts per rental: Require more than one template per rental option (for example, a rental agreement plus a damage waiver).
  • Multiple ways to sign: Customers can sign at checkout success, from their customer account, from an emailed link, or in store on POS.
  • Automation triggers: A contract_signed usage event fires once all contracts are signed, ready to use in Automations.
  • Legally compliant: Signatures are ESIGN, UETA, and eIDAS compliant, with full audit trails and certificates of completion attached to every signed contract.

​
Setup E-signatures

1

Enable the beta feature

Go to Settings > Beta features and enable Contracts.
2

Create a contract template

Navigate to Settings > Risk and find the Contract templates section. Add a template with a name, body (HTML with Liquid), and styles (CSS). Use Preview to render the template against sample data before saving.
3

Attach the template to a rental option

Open the rental method option for the product (calendar, subscription, membership, or resale) and select one or more contract templates to require at checkout. To attach contract templates to many options at once, use the Apply contracts bulk action on the options table.
4

Optional: generate contracts on draft orders

Still on Settings > Risk, under Contract templates, turn on Generate contracts for draft orders if you want unsigned contracts created while a draft is still open. See Contracts on draft orders.

​
Template variables

Contract templates are written in HTML, styled with CSS, and rendered with Liquid. The following variables are available:
  • rentals — array of rentals included in the contract.
  • customer — the signing customer.
  • customer_signature — replaced with the customer’s signature when the document is signed. Required if you want the signature to render in the PDF.

How customers sign

Once an order is placed, Supercycle generates one contract per template and notifies the customer. Customers can sign from any of the following:
  • Online store checkout success page: Sign immediately after placing the order, before leaving the thank-you page.
  • Customer account: Pending contracts are listed in the storefront customer account for the customer to revisit and sign.
  • Email link: Supercycle emails the customer a signing link when the order is placed, and you can resend the link from the order at any time.
  • Shopify POS: Staff open the order in POS and either hand the device to the customer to sign on screen, or display a QR code for the customer to scan and sign on their own phone.

​
Contracts on draft orders

By default, contracts are created when the order is placed. Turn on Generate contracts for draft orders under Settings > Risk to create unsigned contracts as soon as rental lines are added to a Shopify draft order. That lets customers sign before checkout completes, which is useful for POS saved carts and admin draft orders that sit unpaid for a while.
1

Contracts are created on the draft

A draft with a customer and rental lines that require contracts gets one unsigned contract per template.
2

Templates stay the same

The same templates and Liquid variables apply. Draft contracts render against the rental blueprint on the draft line, so you can keep one template for both draft and placed orders.
3

Contracts carry over when the order is placed

When the draft becomes an order, Supercycle reuses those contracts instead of creating duplicates.
4

Staff send the signing request

Ready-to-sign email is not sent automatically for draft contracts. Send the signing link or email from the draft when the customer is ready, including from Shopify POS.
Drafts without a customer, and completed drafts, are skipped.
Generate contracts for draft orders appears when draft-order contracts are enabled for your store. If you don’t see the checkbox, contact [email protected].

​
Contract status

Each contract has one of two statuses: When every contract on a rental is signed, Supercycle emits a contract_signed usage event you can use as a trigger in workflows.

​
Compliance and audit trails

Supercycle e-signatures are legally binding and compliant with the major electronic signature regulations:
  • ESIGN Act (US Electronic Signatures in Global and National Commerce Act)
  • UETA (US Uniform Electronic Transactions Act)
  • eIDAS (EU Electronic Identification, Authentication and Trust Services)
Every signed contract includes:
  • Audit trail: A tamper-evident record of every action taken on the contract, including when it was generated, viewed, and signed, along with the signer’s IP address and timestamps.
  • Certificate of completion: A signed certificate attached to the contract PDF documenting the signing parties, signature events, and audit history — admissible as evidence of intent and consent.
