Sell Digital Products & Downloads
Delivered the moment they pay
Sell software, e-books, courses and any downloadable file, with delivery, license keys and recurring billing handled for you. BillingServ provisions the download the moment an invoice is paid, serves it over secure links, and keeps the whole sale in one place.
Automated delivery · Secure download links · 14-day free trial
Any digital product, delivered automatically
If it is a file your customer downloads, you can sell it here. Attach a license key when the product needs one.
Software & one-time downloads
Sell desktop apps, plugins, installers and tools as a one-time download, with an optional license key issued on payment.
E-books & documents
Sell PDFs, reports and guides. Watermark PDF files with the buyer's details to discourage casual sharing.
Courses & materials
Deliver lesson files, worksheets and resources as a purchase or as a recurring subscription that renews on its own.
Templates & assets
Sell design files, spreadsheets, documents and asset packs. Supported types include PDF, DOC, XLS, ZIP and TXT.
ZIP bundles
Package multiple files into a single ZIP and deliver them together, with the same download limits and secure links.
Licensed products
Sell software that needs a key. Delivery and licensing come from the same purchase, so the customer gets the files and the key together.
Delivery happens the moment the invoice is paid
No manual sending, no watching for payment confirmations. When the payment clears, BillingServ provisions the order and gives the customer a download page straight away.
Files are served over short-lived, signed links tied to the customer's connection, so a link cannot be passed around and reused. Delivery is idempotent and renewal-safe, so a subscriber who renews keeps access without a duplicate order or a broken link.
- Order provisioned
- Download page ready
- License key issued
- Signed link
- Short-lived
- Tied to the buyer
Links are signed and expire quickly, so files stay behind the purchase rather than out in the open.
You decide how downloads behave
Set a download policy per product so the file is as open or as protected as the sale needs.
Open access
Let paying customers download the file as often as they need while their access is active. Best for simple, low-risk products.
Download limits
Cap the number of downloads per purchase. Once the limit is reached, the link locks automatically. Good for high-value files.
Expiring links
Set a time-limited link that expires a set number of hours after the first download. The countdown starts when they first click, not at purchase.
Secure signed links
Files are never served from a guessable URL. Each download uses a signed link that is short-lived and tied to the buyer's connection.
PDF watermarking
Stamp PDF files with the buyer's email, order number and date on every page, so a leaked copy points back to who shared it.
Renewal-safe
Subscribers who renew keep their download access without a new order or a dead link. Access follows the billing.
Bundle a license key with any download
Selling software rather than a static file? Turn on licensing for the product and BillingServ issues a license key on payment, right next to the download.
The key can be activated on a device or server, validated online or offline, and reissued within the limits you set. Because it lives in the same purchase, the license suspends if the invoice goes unpaid and expires if the order is cancelled, with no manual clean-up.
- The download
- A license key
- Activation limits
- Online & offline validation
- Reissues
- Domain locking
Licensing is optional per product. Sell a plain download, a licensed download, or both.
One-time, recurring, or a mix of both
Digital products are not all sold the same way. Charge once for a download, or run it as a subscription that renews and re-delivers on its own.
One-time purchase
Sell a download for a single payment. The customer pays, the files and any license key are delivered, done.
Recurring subscriptions
Charge monthly or yearly for ongoing access, updates or new files. Renewals bill and re-provision automatically.
Overdue handling built in
When a subscription payment fails or goes overdue, access follows the billing so you are not giving files away for free.
Take global payments and stay compliant
Connect the payment gateways you already use and collect in multiple currencies. BillingServ handles the invoicing, tax and fraud screening around each sale.
Apply VAT on invoices and support EU e-invoicing with Peppol BIS 3.0 and UBL 2.1, plus EU VAT number validation. Screen orders for fraud with the FraudLabs Pro integration. BillingServ is not a merchant of record, so you keep your own payment relationships and stay the seller on record, without the revenue cut that model takes.

Frequently asked questions
Selling downloads, delivery, license keys, payments and tax.
What digital products can I sell with BillingServ?
You can sell any downloadable file, including software and one-time downloads, e-books and documents, course materials, templates and ZIP bundles. Supported file types for delivery include PDF, DOC and DOCX, XLS and XLSX, ZIP and TXT. You can also attach a software license key to any product.
How does digital delivery work?
When the invoice is paid, BillingServ provisions the order automatically and gives the customer a secure download page. Downloads are served over short-lived, signed links that are tied to the customer's connection, so the files cannot be freely shared. Renewals re-provision automatically.
Can I limit downloads or make links expire?
Yes. Choose a download policy per product: open access, a capped number of downloads, or a time-limited link that expires a set number of hours after the first download. Once the cap is reached or the link expires, it locks automatically.
Can I sell software licenses alongside a download?
Yes. Turn on licensing for a product and BillingServ issues a license key on payment alongside the download. The same purchase delivers the files and the key, and the key can be activated and validated through the licensing API.
How do customers pay, and can I sell subscriptions?
Sell digital products as a one-time purchase or as a recurring subscription. BillingServ collects payment through the gateways you connect, including Stripe, PayPal, GoCardless, Worldpay, CoinGate and more, so you are not locked to a single processor.
Does BillingServ handle sales tax and VAT?
BillingServ applies VAT on invoices and supports EU e-invoicing with Peppol BIS 3.0 and UBL 2.1 XML, plus EU VAT number validation. It is not a merchant of record, so you keep your own payment relationships and remain the seller on record.
