Shopify App

Stop emailing files manually. Automate it.

Upload your unique PDFs or images, connect them to a Shopify product, and Solara delivers a different file to each customer — automatically, instantly, with zero duplicates.

The problem you know too well

Without Solara

Standard download apps send the same file to every buyer. That forces you to manually email each voucher, ticket, or card one by one. It works until it doesn't — and during a busy holiday or a flash sale, it breaks fast.

With Solara

Upload a pool of unique files. Solara picks the next unused one, emails it to the customer at checkout, and marks it as consumed. No duplicates. No manual work. No mistakes.

Perfect for merchants who sell...

How it works

  1. 1

    Upload your files

    Bulk upload unique PDFs or images — vouchers, tickets, scanned cards, anything. Each file is stored securely and used only once.

  2. 2

    Link to a product

    Connect file pools to your existing Shopify products or variants. No duplicating products — use what you already have.

  3. 3

    Sit back

    When a customer orders, the next available file is emailed to them instantly. Hands-free, duplicate-free, mistake-free.

Built to be reliable

  • One file per order, guaranteed — every file is consumed once and never sent twice.
  • Real-time inventory tracking — see how many files remain in each pool at a glance.
  • Oversell protection — when a pool runs out, the product stops selling automatically.
  • Instant email delivery — customers receive their file within seconds of checkout.
  • Bulk upload — drop thousands of files at once. No one-by-one uploading.

Frequently asked questions

How is Solara different from standard digital download apps?
Standard download apps send the same file to every buyer. Solara delivers a different file to each customer from a pool of unique files. Each file is used once and marked as consumed, so no two customers ever receive the same file.
What file types does Solara support?
Solara supports PDF files and image files (JPEG, PNG). This covers most use cases including gift vouchers, event tickets, scanned prepaid cards, and digital art.
Can I upload thousands of files at once?
Yes. Solara supports bulk upload, so you can drop hundreds or thousands of files in one go. They are stored securely and assigned to orders automatically.
Does Solara prevent duplicate file delivery?
Yes. Every file is marked as consumed after delivery. Once a file has been sent to a customer, it is permanently removed from the available pool and can never be sent again.
