Shopify App
Digital file delivery that just works.
Send the same eBook, PDF, or audio file to every customer — or a unique license key, voucher, or ticket to each order. Solara does both, delivers instantly, and stays reliable even when you're sending thousands of files.
Free to install.
Sending digital files by hand — attaching PDFs to emails, juggling Zapier flows, checking spreadsheets so no one gets the wrong file — is fragile. It breaks during sales spikes, and it eats hours you don't have. There's a reason you're still looking for a better way.
One app. Two ways to deliver.
Most stores sell both — a standard product everyone gets, and something one-of-a-kind. Solara handles both, no extra apps needed.
Shared Mode — one file, unlimited customers
Upload a single eBook, guide, MP3, or PDF and send that same file to everyone who buys it. Sell to ten customers or ten thousand — the download is instant and works the same every time. Perfect for when every buyer gets the same product.
Unique Mode — a different file for every order
Upload your license keys, serial numbers, or vouchers and Solara automatically sends a different one to each order. No customer ever gets a duplicate, and no file is ever handed out twice. Perfect for products that have to be one-of-a-kind.
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 your files once. Solara picks the next unused one, emails it to the customer at checkout, and never sends it again. No duplicates. No manual work. No mistakes.
Perfect for merchants who sell...
POS gift vouchers
Sell PDF vouchers generated by your point-of-sale system online. Each customer gets a unique, redeemable voucher by email.
Event tickets
Distribute PDF tickets with unique QR codes or barcodes. Every attendee receives a distinct ticket — no sharing, no fraud.
Scanned prepaid cards
Upload scanned images of physical prepaid or gift cards. Solara delivers one unique card image per order.
Digital collectibles
Sell one-of-a-kind digital art, numbered editions, or exclusive files where every buyer receives a different piece.
How it works
-
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
Link to a product
Connect file pools to your existing Shopify products or variants. No duplicating products — use what you already have.
-
3
Sit back
When a customer orders, the next available file is emailed to them instantly. Hands-free, duplicate-free, mistake-free.
Your brand, not ours
Custom "From" sender address
Every delivery email comes from your own domain — not from noreply@some-app.com. Your customers see your brand in their inbox, building trust and keeping the experience 100% on-brand. No third-party branding. No awkward forwarding. Just clean, professional delivery that looks like it came straight from your store.
Built to be reliable
- One file per order, guaranteed — in Unique Mode, every file is sent once and never reused.
- 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.
Built for big catalogs
Upload thousands of files without the headaches
Other delivery apps slow down, freeze, or fail when you upload a lot of files at once — right when you can least afford it. Solara doesn't. One merchant recently uploaded 8,000+ files in a single go: nothing crashed, nothing timed out, and not a single file went missing. Whether you're adding one eBook or ten thousand license keys, uploads stay fast and dependable.
What merchants are saying
"This app has solved the problem of automation that I have been trying to figure out for a couple months. This new update that allows the 'from' sender to be customized is a great update! It is now perfect for our company! You have done great work with this app and I appreciate the time and energy that it saves us!"
Frequently asked questions
- Can I send the same file to everyone, or a different file to each customer?
- Both. In Shared Mode, you upload one file and every customer who buys it gets that same file. In Unique Mode, you upload a batch of different files and each order automatically receives a different one, with no duplicates.
- How is Solara different from standard digital download apps?
- Standard download apps only send the same file to every buyer. Solara does that too — and it can also send a different file to each customer, one at a time, with no duplicates. Each unique file is sent once and never reused.
- 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. In Unique Mode, once a file has been sent to a customer it is set aside and never sent again, so no two customers ever receive the same one.
