# Customers and sites

## Customers

Company name, head office, accounts and sales emails, staff contacts, credit limits, optional branding.

## Sites

Each site belongs to one customer: address, GPS, contacts, warnings. The same physical building can exist as a separate site under another customer (a shopping centre with two facilities clients). Assets, contacts and history stay with that relationship.

DoorOps may flag similar addresses inside one customer to prevent accidental duplicates. It will not merge sites across customers.

## Site warnings

Engineers must acknowledge a site warning before starting work. Admin notes on the customer are office-only.

## Contacts

Customer contacts and site contacts are separate. A site contact is not automatically a customer contact.
