HandShake Invoicing Pro adds an extra menu item and unlocks features inside the free plugin’s existing screens, but does nothing on its own.

The Pro plan removes the 3-client limit and unlocks price groups, payment reminders, the revenue dashboard, and bulk exports.

Activating your license

1. Purchase a Pro license at gethandshake.eu
2. You will receive a license key by email
3. Go to HandShake → License in your WordPress admin
4. Paste your license key and click Activate

A green indicator will confirm the license is active.

Deactivating your license

Go to HandShake → License and click Deactivate. This frees the license so it can be activated on a different site. Your data is not affected.

Updates

Pro updates appear in Plugins like any other plugin, as long as your license is active. WordPress checks for new versions automatically and shows an “Update available” notice when one is ready.
