If a guest ends up with more than one profile in Preno, you can combine them by removing the duplicate guest from a booking and re-adding them, then selecting the profile you want to keep as the merged record.
Open the booking you want to update.
Click Edit booking
Scroll down to Guest details
Click the red cross next to the guest's name to remove them from the booking.
Click Edit guest details.
Enter the guest's last name. Their existing profiles will show as suggestions on the right.
Select the profile you want to keep, then click Use this profile.
Repeat these steps for any other booking linked to the duplicate profile, and always select the same suggested profile — for example, the first "Sandy Smith" at the top of the list — so every booking points to one profile.
If the guest has already checked out, roll back the booking first to edit the guest, then check them out again. If the booking has a Xero deposit attached, contact the Preno support team for assistance before proceeding.
