You can switch to the paid version of RAYNET CRM at any time during the trial version or even after its expiration. You will go through all the data you’ve entered into the system during testing.
In Settings you will see the section "Upgrade to professional edition" and the price per month. Click the Start with profi edition button. You'll see a window to check your billing information. After completing and checking it, click on the Proceed to payment button, here we’ll verify your card where the monthly payments will be deducted from.
If you need to adjust the number of licenses before activating the paid version, go to Settings> User Management after logging in, where you can add or remove licenses (as you can read here).
You can then switch to the paid version via Settings> Enter Billing Information & Start Sharp.
