Mobile Invoicing Suggestion

Trini

I'm new to wave and noticed that there is no mobile terminal service (Quickbooks now offer this). At my company we use field associates and a terminal that integrates with wave would be perfect. Knowing that wave does not offer this service I attempted to try and troubleshoot by creating a new user in the settings but notice that the options are limited to (admin, Editor, Payroll or viewer). Would it be possible to create a bare bones invoicing option without giving viewing access or any access whatsoever to the user, except for creating and sending invoices, also making the invoices sendable via text message or at least a fully custom user option so I can choose exactly what I want a user to do?
