This block reads live subscription data, so it only runs inside a real customer portal. The animation shows what subscribers see.

What it does

Subscribers pick the exact day their order arrives, and the billing date shifts to match.

Why it exists

For merchants shipping perishables, where arriving on the right day matters. Billing moves with the date, so nothing sits on a porch.

How to install

  1. Copy the code above, or download the .html file.
Your portal
  1. Go to Storefront → Customer Portal → Branding → Layout and click Add custom extension.
  2. Pick HTML with embedded CSS and JavaScript and paste the whole file into the code editor.
  3. Swap anything the file asks you to, like [BRAND], product names or Quick Action IDs.
  4. Save, click + to add it to the layout, then Publish. Check it on a test subscription’s magic link with ?forcePreview=true, since some scripts don’t run in Preview.

Blocks are shared as-is by the people who built them. Read the code before you add it to your portal, and test it with a test subscriber first.
