To show an estimated delivery date on a Shopify product page, use an app where you enter your processing time, shipping time and cut-off once, and it works out the arrival date for each shopper. Dateria Estimated Delivery, which we made at GRAMSHIFT, shows lines such as "Order within 2h 14m 05s and get it between Wed, Oct 21 and Mon, Oct 26", and the Free plan has no limit on page views or products. The date counts only your working days and skips your holidays.

What you set, and what shoppers see
The three ways, compared
1. Write it in the product description
"Ships in 3 to 5 days" is easy to add, but the shopper has to count the days, and the text never moves past weekends, holidays or your cut-off time.
2. Add code to the theme
A few lines of code can add days to today's date. Weekends, holidays, a cut-off time in your time zone, out-of-stock items and other languages each need more code, and theme updates can remove it.
3. Use an app
An app works out the date for each order time and adds the rest: countdown, holidays, languages and rules. Dateria does this inside your theme without code edits. Turn the app embed off and the product page is as before.
How the date is worked out
- Two steps, like a real shipment. Processing time (the business days you need to pack an order) plus shipping time (the days the carrier needs).
- Cut-off time. Orders after your cut-off, in your store's time zone, start the next processing day. Before the cut-off, the page shows a countdown.
- Your days, not every day. Choose the days you ship and the days carriers deliver separately. Public holidays are skipped by both counts, and a day when only your store is closed, such as a summer break, stops shipping while carriers can still deliver.
- Holidays in one click. Import a country's public holidays for this year and next, and remove any day before saving.
- Out of stock. For a variant that is out of stock but still for sale, hide the date, add extra days or show a different message.
- In the shopper's language. Weekday and month names follow the language of the store page, and you can translate the message.

How to set it up
- Install Dateria Estimated Delivery from the Shopify App Store. The app opens on Home with four steps.
- Enter your processing time, shipping time and cut-off time, then your processing days, delivery days and holidays. Try a Friday evening order in the preview, then click Save.
- Pick a look in Design (text line, timeline or box) and check the message in your store's language.
- Click Enable app embed. The theme editor opens with Delivery estimate switched on. Click Save.
- Switch on Show on store and open a product page. Nothing shows on your store until you do this.
The Free plan covers every product page with no limit on page views or products, including cut-off time, working days and holidays, 3 rules and the estimate on cart lines and orders. Pro is $9.99 per month or $99.90 per year with a 7-day free trial and adds unlimited rules, rules by the shopper's country, rules that run on set dates, and CSV export and import of rules.

Limits to know
- The date is an estimate from the times you enter, and carriers can be late. Keep your shipping time to what your carriers really take.
- Shopify's own "Deliver by" date at checkout is counted separately. Enter the same shipping days in your Shopify shipping settings and place one test order to compare.
- Collection pages and the home page are not covered.
- Checkout and the thank-you page are not changed by the app. The estimate reaches the order through the cart line.
- Cart dates are brought up to date when the shopper opens any page of your store. A shopper who goes straight to checkout from a link, such as an abandoned checkout email, keeps the dates from their last visit.
