Flash Sale in One Task

/flash-sale  Builds a flash sale end to end: sale collection, automatic discount with start and end, and an email draft, with one approval.

Add to Sidekick

Add opens your Shopify admin with the skill prefilled; review it there and click Add. If nothing appears, use Copy and follow the steps below.

Personalize before you add

Values come from your store profile when set. Leave a field blank to keep the placeholder and fill it in Sidekick.

The skill

Suggested shortcut: /flash-sale
Set up a flash sale on [PRODUCTS OR COLLECTION] at [PERCENT] off from [START] to [END], shop timezone.

## Steps
1. Resolve the products. Check stock for each; exclude anything out of stock or with fewer than 5 units and tell me.
2. Check active and scheduled discounts for overlaps with these products in the sale window.
3. Plan three things and show them together before doing anything: a collection named "Flash Sale" containing the products, hidden from navigation; an automatic percentage discount limited to that collection with the exact start and end; a Shopify Email campaign draft with a subject line, a one-paragraph body in the store's voice, the product grid and the end time.
4. Ask for one approval. Only after a clear yes, create the collection, then the discount, then the email draft. Report each step as done, with links.

## Output
The plan as three short blocks, the stock exclusions, then "Create all three?"; after approval, three confirmations.

Do not send the email; leave it as a draft. Do not change product prices directly; use the discount. If any step fails, stop and say which one.
How to add it to Sidekick
  1. Click Add to Sidekick above. Your Shopify admin opens with the skill ready to review. Click Add. Done.
  2. If the button does nothing in your store: click Copy skill, open Sidekick in your admin, type /, choose Create new skill, name the shortcut flash-sale, paste the text as the instructions, and save.
  3. To run it, type /flash-sale in Sidekick. Sidekick keeps up to 25 skills; manage yours from the skills menu.

What you get

A complete sale scaffold in one approval: collection, timed discount, and an email draft waiting in Shopify Email. This is the compound-task capability Shopify added to Sidekick in 2026, packaged.

When to use it

Weekend promotions, clearing a seasonal range, reacting to a slow week.

Variations

  • “Also draft an announcement-bar line and a social caption”.
  • “Use a code instead of an automatic discount” for influencer-driven sales.

Limits

Sidekick can’t schedule the email send; you do that in Shopify Email. Themes without a sale badge won’t show the strike-through price automatically.
