How I solve it

What I build

I build a Shopify app that opens and closes collections on schedule from metafield dates. There is a deliberate line between a real availability change and a display-only notice, so a “closing” notice does not accidentally remove products. A storefront countdown theme extension shows the window, and its wording is editable per collection. Every change is written to a run history, so when a window closed is something you can prove rather than remember. Where the build needs it, the same schedule can carry to a checkout extension, so the storefront and the checkout tell one story.

The process

How it works

6 steps. Scope and a fixed price are agreed before the first one.

  1. Define the schedule convention

    as collection metafields (start and end dates).

  2. Run a scheduler job

    that reads the dates and publishes or unpublishes through the Admin API.

  3. Separate real availability from notices

    with a managed availability mode.

  4. Add the storefront countdown

    as a theme app extension, mobile-safe and clear of banners and widgets.

  5. Carry the window to checkout

    with a checkout schedule extension.

  6. Log every change

    in a run history, so a closed window is auditable.

Handover

What you get

  • Collections that open and close on schedule, from dates you set in metafields.
  • A storefront countdown, with wording editable per collection and safe on mobile.
  • A run history that records every change — proof, not memory.
  • A checkout extension where it fits, so a time-boxed notice stays consistent with the storefront.
  • A clear separation of availability changes from display-only notices.

Proof

Done before, with dates and numbers

Client work Done for real clients. Client details are anonymised.

Before → after

Collections that had to be opened and closed by hand now change from metafield dates, with a storefront countdown. The app went live on the client’s own app subdomain on 2026-07-22, built in 25 commits (2026-04-21 → 2026-07-28).

    production

    collection scheduling from metafield dates, a storefront countdown and a run history, live on the client's own app subdomain from 2026-07-22; 25 commits over April–July 2026.

  • The App Store edition of my collection scheduler

    deployed, not submitted

    standard Shopify OAuth distribution, a paid plan with a trial, GDPR compliance webhooks and a timing-safe cron endpoint. App Store P0 items are still open, so there are no merchants yet; it derives from code a client paid for, so I am not naming it until the rights decision is settled.

A note from Daniilbefore you decide

When you don’t need this

If a drop happens once, a manual publish the night before is fine and free. If you do not need a countdown or a checkout notice, a plain metafield automation may be more than you need.

Questions

What people ask about this

Does closing a collection delete products?

No. It changes availability, reversibly. The products stay; the window opens and closes on schedule.

What if the scheduler job fails?

A run history records each change, so a missed window is visible. The job is per-shop and logged.

Can the countdown wording differ per collection?

Yes. The wording is editable in the app, per collection, and the storefront shows it through a theme extension.

Is this live for real merchants?

The client line is in production. The App Store edition is deployed but not submitted, and its P0 items are still open.

Does it require Shopify Plus?

No.
