There is a setting that you can use to choose whether to automatically updated an invoice date to match the new date that the job has been moved to or whether it will remain the same, to be updated manually when you edit the invoice itself.
In the Web Portal, go to the Settings Cog > Accounts > Invoices > Scroll down to Update Invoice Options.
If you would like the invoice date to change when you change the job date, select Yes in the invoice update option.
If you would like the invoice date to remain the same, select No in the invoice update option.
Once you've selected / changed the options, then Save at the bottom of the page.
