Now on the Shopify App Store
The delivery date always lands on the order.
DateLock lets your customers choose a delivery or pickup date at checkout — saved to every order, enforced on every checkout including express, and built so it never breaks your store.
Date-sensitive orders fail two ways. DateLock fixes both.
Every incumbent loses merchants the same way — the date slips through, or the picker breaks the store. DateLock is engineered so neither can happen.
Everything to collect a date — and nothing that risks your checkout.
On every order
The chosen date is written to the order as a metafield, tag, and attribute — visible and filterable for fulfillment. It never gets dropped.
Every checkout, incl. express
A server-side validation requires a date before checkout completes — covering Shop Pay, PayPal, Apple Pay, Google Pay and Buy-it-now.
Never breaks checkout
DateLock fails open by design. If it ever can’t run, checkout still completes and only date collection pauses — never a lost sale.
Your delivery rules
Set cutoff times, lead and preparation time, and blackout dates. Customers can only pick dates you can actually fulfill.
Shows everywhere
The date appears on the Thank-you page, the Order-status page, and — with a paste-in snippet — the order-confirmation email.
Leaves your theme alone
DateLock installs as a theme app embed — no theme code is edited. Switch it off or uninstall and nothing is left behind on your cart or checkout.
From checkout to fulfillment, the date carries through.
Customer picks a date
A clean date picker appears at checkout, greying out days your rules don’t allow — cutoffs, lead time, blackout dates.
DateLock enforces & saves it
The date is required before checkout can complete, then written straight onto the order — server-side, on every path.
You fulfill with confidence
The date is on the order detail, filterable by tag, and shown on the thank-you, order-status, and confirmation email.
The date, from checkout to fulfillment.
