If you've accidently invoiced/free of charged/aborted a job, then you can turn it back to a job. You will need to be a level 5 administrator, if you aren't a level 5 users then the option wont appear for you, please speak to your manager.
Open the job and click on Job Preferences in the top right corner. A form appears. Click the tick box to confirm you want to convert it back to a job. Type in why you want to convert it back to a job and click save.
Please note, if you're converting back an invoice, CommuSoft will not re-use the invoice number associated with this record. Invoices will continue to be created sequentially.
