Pick a person as the recipient — company details come along automatically. When you select a contact person as the customer on a quote or invoice, the linked company now appears automatically as a header line above the name. If the person has no address of their own, the company's address is used — so the recipient block is never blank. If the person does have their own address, that one still wins.
Switch between "To company" and "To private person". For a person with a linked company you can now choose, per document, who it is addressed to. "To company" (the default) carries the company name, company address and VAT ID; "To private person" addresses the person only — no company line and no company address.
The linked company is visible right in the customer picker. In the customer field's search, every person now shows its linked company as a secondary line, so you can see at a glance that you can pick the person and the company comes with it.
Preview and PDF match exactly. The address preview in the editor now shows the same lines that end up on the finished document — including the company line and the inherited company address.
