Guidance for Future Use of E-Invoicing Fields in Enterprise

From this Documentus post (do click through for the whole conversation!) - guidance for a NZ customer who wants to get ahead on e-invoicing prep. From Chai:

For now though, IRD in the Tax ID field and NZBN in the e-invoice ID make sense - the current plan is to use the e-invoice ID for any regional specific needs and having the E-invoice Scheme identify that regional specific scheme. For invoice method, they can switch it to “e-invoice”, but it won't do anything until there's an integration available. If they don't want to do that up front, we have a way for them to edit multiple after the fact.
