Activate
After purchase you receive the license key (format XXXX-XXXX-XXXX-XXXX) in your receipt email and on your account page at pihlfelt.se. Install the Pro zip (Pro automatically deactivates the free version — settings and data carry over), go to Cost & Margin → Premium, paste the key and click Activate.
Moving between sites
The number of concurrent sites is set by your plan (1, 5 or 25). To move an activation: deactivate the license on the old site first, or release the site from your account page at pihlfelt.se. Staging sites count separately — contact support if you need an extra activation for testing.
Updates
With a valid license you receive Pro updates straight in the WordPress update flow, like any other plugin.
If the license lapses
The plugin keeps working — including Pro features on your existing data — the plugin never reprices anything because a license lapsed. What stops is updates and support, and scheduled runs fall back to monthly. All data, prices and the entire journal remain; renew later and everything is back to normal — nothing needs reconfiguring.
