How to run a sale on Shopify

Most stores run sales the same way: someone discounts products the night before, and someone restores them the morning after. Both ends are error-prone, and both are avoidable.

A week before: mark the products

Tag everything that is in the sale, with a tier in the tag if you are discounting at different depths — “sale-20”, “sale-30”. Tagging is itself a bulk task, filtered by collection, vendor or margin, and it gives you a stable, reviewable selection that will not shift when a smart collection re-evaluates.

A few days before: build the tasks

1. One task per tier: filter on the tag, copy price into compare-at, reduce price by the tier percentage, round to your usual ending.
2. Set the start time to the moment the sale opens.
3. Set the revert time to the moment it closes.
4. Check the task list shows both times for every tier.

The day before: rehearse

Build the same task filtered to five products, schedule it for five minutes ahead with a revert ten minutes later, and watch what happens on the storefront. This catches the two failures that actually occur: a theme that does not render compare-at price the way you assumed, and a filter that matches more than you meant.

During: watch the log, not the clock

When the start time passes, the task list shows the run and the log lists every variant. If items were skipped, they are listed with a reason — usually a product that changed between scheduling and running.

After: let it end itself

At the revert time the previous prices are written back. If you also want the reference prices gone, run a cleanup task that clears compare-at price and removes the sale tags — that is the state your catalog should return to, not “discounted forever”.

What about discount codes?

Codes are the right tool for cart-level offers, newsletter incentives and anything you want to attribute to a campaign. Price changes are the right tool when browsing customers should see the sale price on the product page. Plenty of promotions use both.
