Hi,
Unfortunately our invoicing doesn’t have the functionality to group invoices into projects or jobs. Each line item has a limit of 150 characters.
If you need to write more than this then one option would be to switch to Classic invoicing using the toggle at the top of your account and write a short line item description and use the notes box to give a more detailed description/breakdown or justification of their costs. Or you can also attach a file with whatever job specifics, receipts, etc you want to include. I hope this helps and feel free to get in touch if you have any further questions or queries.
