Any client with a client area. The code is your company's; your contacts with administrative or full access see it on their Account page.

On the first invoice the referred company pays, excluding tax, once per company. A credit top-up isn't a purchase and doesn't count.

No. It joins your credit, in the currency of the referred company's invoice, and comes off your next invoices.

As long as it hasn't paid anything, it can type it in its client area, on the Account page. After its first payment it's no longer possible.
