See every vendor your firm's companies buy from
Firm brain adds Global contacts, showing each vendor across companies and the account it is usually booked to.
Firm brain has a new Global contacts tab beside Skills. It lists each vendor your firm's companies buy from, grouped by TIN where there is one, so the same supplier is not counted separately under every company.
What each row tells you
Search by vendor name or TIN. Each vendor shows how many companies use it and, once learning is on, the Usual account they book it to and how widely that is shared, such as "67% · 2 of 3 companies". Open a vendor to see the account by company and the bills behind it, and use Forget this bill to remove one that should not count.
For firm admins: learning from bills
The vendor list fills from each company's contacts in Juan. The usual account needs learning, which starts off. Choose Turn on for all companies… and pick the date to read bills from; Pause learning stops it, and what was learned stays. Learning reads Juan and never changes it, and owner-private companies are left out.
The first pass across many companies takes a few hours. Learning does not send anything to Juan or change a company's sending settings.
