When you registered with OTA Sync for free in the first 14 days you were set up with dummy data rooms, reservations, and prices so you can check the look and feel of the system.
If you want to exit this trial version and upgrade with your actual data you need to go on the button UPGRADE that is located on top of the screen.
When you click on it you will be sent to the rooms adding screen where you should add all your room types that you realistically have in your property.
Note: You can import all your rooms directly from Booking.com if you have listed your property already. (check the section Booking.com under the Continue button)
When you finish adding rooms click continue and choose your subscription either Monthly or Annual and enter your payment details.
After that, you can enjoy the full power of the OTA Sync software.
