Both licences give you the full SonaChat, with the source code. The only difference is whether anyone pays you to use it.

You can sell the service SonaChat gives your clients. You cannot sell or give away SonaChat itself:
Your licence key carries it. The key is checked on your own server, with no call to us, and nothing is ever switched off by it.
With a Regular key, when a second client company is added or client billing is turned on, the panel shows a short note that this needs the Extended licence. It is information, not a lock — everything keeps working.
You pay only the difference: $110 USD (€110 in the euro area). The upgrade link is in the receipt of your Regular purchase and on the download page. Paste your Regular key, pay, and a new Extended key appears on the screen and in your e-mail.
Paste the new key in the panel, under System, and the note disappears. Each Regular key can be upgraded once.
SonaChat keeps running — we never switch it off. What stops is support and updates for that key. Moving to the licence that fits brings both back.
If SonaChat does not work as described on this page and in the manual, and we cannot fix it, we refund you in full. Write to support@saoirsesoftware.com within 30 days of buying, tell us what goes wrong, and give us the chance to fix it first. The same applies to the $110 upgrade.
We do not refund a change of mind, a feature SonaChat never claimed to have, or a server that does not meet the requirements in the manual. That is what the live demo and the manual are for: try them before you buy.
The source code is yours the moment the payment clears. That is why, at checkout, you tick that you want the download to start at once and understand that this ends the 14-day right to cancel that EU law gives consumers. A refund ends the licence it refunds.
