Adding / Removing Night(s) to an Invoice
To add a night from an invoice, open the invoice, and click on the "+" sign that is located next to the first date of the reservation or the last date of the reservation. If the guest wishes add nights to the beginning of the reservation, then you would click on the "+" sign next to the original arrival date. If the guest wishes to extend his / her stay, then click on the "+" sign on the original departure date.
Adding days or weeks to an invoice - Step #1
Go the invoice you wish to modify and at the top of the screen is the "Details" tab, click on it.
Note: the process we are about to embark on will regenerate your invoice. ALL payments will remain, but any changes you've made to rates, additional fees, deposits, etc.. will be lost. I usually print the original invoice so when I regenerate the invoice I can easily restore any special rates, fees, deposits, etc.
