When you open up the dropdown in a booking you will see the Booking Reference, which is a unique system defined alpha-numeric code.
You will find the same reference number on all system generated documents such as Receipts, Invoices, Bill's and Quotes. See the example Bill below.
Can I Change The Reference Or Turn It Off?
It is not possible to change this booking reference, it is a system defined reference that is hard coded once the booking is created. But you can turn this reference off on all of the financial templates.
Go to
>>> Settings
>>> Templates
>>> Financial
And choose the template you want to edit (Receipt, Invoice, Quote & Bill).
To access your Bill Template CLICK HERE.

You can use the Pre/Post Products Text boxes to enter any general information you may want to add to the Receipt, Invoice, Quote or Bill templates (such as payment terms). In the Pre/Post Products Text boxes, you will also see that you can use tokens to add specific information about a booking (such as Start Date, Booking name, etc.).
