You can view and modify your Client Invoices as System Message Templates.
The following templates are relevant:
- Client Invoice
- Client Invoice Payment Receipt
- Client Invoice Overdue Notice
Invoice Headers
One part of Client Invoice templates is the Invoice Header, given by the [invoiceHeader] magic tag. That, too, is customizable.
You'll find the place to do so in Business Center >> Setup >> Invoicing Config >> Miscellaneous >> Invoice Header Extra.
