Electronic software distribution is more than sending an installer. A workable setup connects the correct version, the buyer’s licence and clear installation instructions.
## Keep delivery and activation separate
BIG can deliver software files and licence keys. Your application or licensing service must decide whether a key activates the product, how many devices it permits and how revocation works. A delivered string is not an activation system.
## Package for the supported environment
Name operating systems and versions explicitly. Keep Windows, macOS or other installers mapped to the right product variant. Include a version number, release notes and the support policy in the download package.
## Design an update policy before selling
Tell buyers whether the price covers a major version, a period of updates or future releases. Keep previous installers where your policy requires them. Test whether a product-file update affects past buyers before using it for a rollout.
## Track exceptions
Plan how to handle an empty key pool, a failed activation, a refund and a device replacement. Keep order and key exports secure. Only collect information required for the licensing and support workflow.
## Your practical action plan
-
Prepare the deliverable.
Keep an original backup and publish a clear version. List the formats, compatibility and licence scope before the customer purchases.
-
Connect and test in Shopify.
Map the file, link or key to the right product and variant. Use the appropriate standard, custom or scheduled delivery mode. Check a controlled purchase on desktop and mobile.
-
Choose capacity and monitor it.
Use catalogue size and expected monthly transfer to choose a plan. Track actual usage and support questions after launch, especially before a promotion.
## Before you publish
-
The product page matches the actual files, access and timing.
-
A sample or preview reflects the product customers receive.
-
The purchase, email and mobile access route have been tested.
-
Compatibility, licence terms and support contact are easy to find.
-
Capacity and costs have been checked against the current plan.
