Please add a field in Business Information for a S-Corp's EIN#. This is a primary piece of information when sending quotes to companies (at least in the USA) and needs to be either under the Logo (optional) or a field in Business Information.
@TLCINC_18. Thanks for the feature request here! While there isn't an official way of adding this as a fill out field, you can technically use the second address line to put that number in there. While we don't have this immediately available, we're looking at improving our invoice customization in the near future (still no ETA).
