How do I update a digital product after people have bought it?
Updated
What updating involves
To update a digital product after selling it, replace the file in your store so existing buyers get the new version from the same link. Put a version number and date in the file, keep a short changelog, and email buyers what changed. Decide who gets updates before you launch.
Free updates for life, updates for a year, or paid upgrades. Say which on the product page from day one. Changing the rule later annoys the buyers who supported you first.
Replace the file in the store
Most platforms let you swap the file so existing buyers get the new one from the link they already have.
Check yours does before you promise lifetime updates, because not all of them do.
Version and log it
Put a version number and date inside the file, and keep a short changelog page.
When a buyer asks whether they have the latest version, that page answers it without a conversation.
Tell people — it sells
An update email is one of the best marketing messages you will ever send. It reminds buyers you exist and proves the product is alive.
Keep it short: what changed, where to get it, one line about what is next.
