Can I save a different email address to an invoice than the one on the original estimate (ie without having to type it in every time)?

Hello jeffcarr,

Unfortunately you will need to change this every time, as you can only save one email address per customer.

If you would like for the developers to look into implementing this as a feature in future updates, please use the feedback option under the cog wheel - this submits your suggestion directly to them.

Thanks,

Talia
