Before we get in to how to close a job without invoicing, there is an important setting that will impact your ability to do this effectively. In My Office > Company Preferences you will find a toggle switch labelled as 'Allow Invoicing Prior To Job Completion'.
If this switch is set to Yes then you will not be given the option to close out the job without invoicing no matter what current status your job is in.
If this switch is set to No then you will be shown a dialogue box that lets you know that you cannot invoice a job until it is in the 'Completed' status.
Once you have changed the status of your job to the 'Completed' status you will be free to select the invoice option without the block. You'll notice that you now have a third option- to Close Out & Invoice Later.
This option will place your job in to the (1)'Job Closed' status! If you need to reopen the job at any point then you can select the blue, clickable option to the right of the status labelled (2)'Reopen This Job'. You can also return to the job if you find that you would like to (3)invoice it later on down the road!
