Server-side validated terms acceptance and age verification built on Shopify Checkout Extensibility. No workarounds — real compliance your legal team will love.
Not another cart-page hack. CheckMate runs inside Shopify's checkout where it actually matters.
Terms acceptance is validated on Shopify's servers before the order completes. Customers can't bypass it by disabling JavaScript or manipulating the page.
Built natively on Shopify's Checkout Extensibility platform. No theme modifications, no script injections — just a clean, official integration.
Require customers to confirm their age before completing checkout. Configurable for 18+, 21+, or any custom age threshold your business requires.
Write your own terms, disclaimers, or consent language. Link to your full terms & conditions, privacy policy, or any legal document.
Every acceptance is timestamped and stored on the order as metafields. Proof of consent when you need it for disputes or audits.
Renders natively in the Shopify checkout flow. Matches your checkout branding automatically. No jarring popups or redirects.
Up and running in under two minutes.
One click from the Shopify App Store. No theme editing, no code, no developer needed.
Set your terms text, enable age verification, customize the legal language to match your business needs.
A required checkbox appears in the checkout. No agreement, no order — enforced server-side by Shopify.
One plan. Everything included.
Flat rate. No per-order fees. No hidden costs.
Stop relying on cart-page scripts that customers can bypass. Get real, server-validated compliance.
