How does “The tabs” work on the Contact Sync page?

Suppliers is the register. Coverage is golden records down the rows and organisations across the columns — a tick where the contact exists, + Add where it does not, so replicating a contact into a sister company is one click. Needs review lists records whose members look wrong (named after one of your own companies, disagreeing on VAT or company number, carrying two bank accounts) and pairs that look like one supplier split in two. Who is who holds the research verdicts to confirm and the Xero changes to approve. Duplicates groups families inside one organisation — the survivor, then each other member with its postings and what becomes of it. Nothing behind them lists active contacts with nothing posted in Saral or in Xero; approve archives each in its organisation, Keep is remembered so it is never offered again. Where: Contact Sync (/accounts/contacts-harmonisation).
