Refactoring of the Print & Send:

Why ?
Invoicing communication channels have multiplied with the advent of electronic invoicing.
Clients want to receive PDF and electronic formats (UBL, Factur-X, Factura-e,...) in different ways
(email, peppol, post, ...), depending on the localization and their needs.
Mandatory B2G declarations of invoices are also multiplying.

The current Print & Send allows for that flexibility, but at the cost of becoming:

- quite messy: you have many checboxes that you can chose at the same time with different
meaning (B2B, B2G, sending method,...)
- hard to use in batch: as you can't setup invoice channel by partner, you need to chose
each time you click on Print & Send. Then some magical things happen to apply the right checkbox
to the right invoices.
- technically complicated: because some options are about format, some about how to send, about
one or more invoices.
- the current solution invites the user to "multiply the channels", by clicking everything
and send his invoices to his customers via all the channels possible. This creates a situation
where E-Invoicing creates a mess for accountants that receive the same invoice via multiple sources,
further causing potential duplicates, double payments, etc.

How ?

- Choose ONE channel of communication per partner to send his invoice (by Post, manual (download),
by Email, by Peppol)
- Synchronize mandatory B2G declaration with invoice sending
- Choose if a B2B E-invoice format needs to be generated (UBL, Factur-X, Factura-e,...)
- Make invoice batching sending easy by applying selected defaults, this also mean B2G declarations
will be applied by default if relevant.
- We also added at partner level the possibility the select an invoice report template, as well as
mail templates.
