Shopify Estimated Delivery Date Without an App

An estimated delivery date is arithmetic, not a subscription.

The App Store is full of apps that show "Order within 4 h 12 m, get it between Tue 14 and Thu 16" — for $5–15 every month, plus a script on every page load. The date itself is just math: today plus your handling time, counted in business days, printed next to your add-to-cart button. Your theme can do it. This page shows the three ways to display delivery estimates in Shopify, what a snippet handles on its own, and where a paid app actually earns its fee.

Three ways to show an estimated delivery date

  1. Native checkout settings. Shopify can show delivery dates at checkout when your shipping profile and rates are configured (Settings → Shipping and delivery). That covers the checkout step in many regions. It does nothing on the product page — and the product page is where the buying decision happens.
  2. One file in the theme. A snippet or Custom Liquid block on the product template: take today's date, add your handling days in business days, print the range next to the buy buttons. Edit the numbers once, done. You own the file — no account, no per-pageview script, no subscription to renew.
  3. A monthly ETA app. Justified when you need live carrier API integration, per-product handling rules across hundreds of SKUs, or holiday calendars maintained for you. If you ship from your own stock with a known handling time, it is a subscription for a date calculation.

Why most pasted delivery estimates get it wrong

Hard-coded dates. "Ships by December 15" pasted in November is a broken promise in December. Compute the date from the current day at render time so it rolls forward automatically.

Weekends counted as workdays. Order Friday evening plus 2 handling days is Tuesday, not Sunday. Business-day math is the difference between an estimate customers trust and one they screenshot and complain about.

No cut-off time. "Ships today" means nothing without a cut-off hour. Orders before 14:00 count from today; orders after that count from the next business day.

Overpromising the range. The estimate sets the expectation your fulfillment has to hit. An honest 3–7 day range beats an optimistic 1-day promise — the second creates the support inbox, the first prevents it.

What you do not need before an ETA

  • A delivery-estimate app with a monthly plan
  • A checkout-customization app to repeat the promise at checkout
  • A countdown-timer app to add urgency on top (the KERN pack covers that too)

FAQ

Can I show an estimated delivery date on Shopify without an app?

Yes. Add a snippet or Custom Liquid block to the product template that computes today plus your handling days and prints the range. No app needed.

Does Shopify show delivery dates at checkout?

Shopify can display delivery estimates at checkout when your shipping settings support it (Settings → Shipping and delivery). The product page, where most decisions are made, needs a theme file.

Does the delivery estimate work in Dawn?

Yes. Dawn supports snippets and Custom Liquid blocks, and the file is pure Liquid that renders in any Online Store 2.0 theme.

Do I need JavaScript for the ETA?

No. The date is computed in Liquid when the page renders, so nothing extra loads in the browser.

How do I handle weekends and holidays?

Count only business days and set a cut-off hour. Orders after the cut-off start counting from the next business day.
