Every company you deal with, once: customer, vendor, partner or investor, often several at the same time. Cordango can research each one for you.
Sales, finance and purchasing deal with the same companies, and each of them usually keeps its own list. Here a company exists once, with its legal identity, its registered and head office addresses, and a named owner in your team. The CRM, Invoices, Purchase Requests, Vendors and the Asset Register all point at that record, so an address corrected in one place is corrected everywhere. Ask for research and Cordango files what it finds, each value with its source and how far to trust it, without writing over what you entered.
Each of these points at Organizations instead of keeping a copy of its own, and says what for.
