Customers · Customer Book
Put purchase history and credit beside the customer at the till.
Purchase history, returns and balances lose value when the counter cannot retrieve the customer record.
This is a capability inside Lightning Pharos, not a separate product.

Find the customer by phone and attach the transaction.

03 · What it needs
Ready inside every Pharos workspace.
No additional module is required before this capability can be switched on.
04 · Where it stops
The boundary is part of the product.
Phone and email are not globally unique, and the module does not yet provide contact-preference or consent management.
Bring your exact workflow to a walkthrough and we will show where Pharos fits and where it does not.
