The following invoice features are customizable from your Billing settings:
Add your color and logo to the email and the hosted page.
Add a note or memo (up to 500 characters) and a footer (e.g. for legal requirements).
Add up to 4 custom fields to add customized data to invoices that are a part of your industry or region’s requirements. You can add this on a per-customer basis in the Dashboard and API, which will then present those fields by default on all invoices created for that customer. This can be overridden at the invoice level for one-off changes.
Specify the number of days after which the invoice is sent that payment is due.
