# Link the records that belong together.

A customer and its service visits, a project and its suppliers. Describe the link once, and it shows on every record on both sides, ready to filter by and to add up.

## Say which records belong together.

The Agent sets relationships up today: name the two kinds of record and how they relate, and it makes the link, with a name for each side. Settings list every relationship, and archive or restore one.

> Link each service visit to its customer, so a customer's page shows all its visits.

- **One to many, or many to many.** A customer has many visits. A project has many suppliers, and a supplier serves many projects.
- **On both sides.** Every record shows its links in Related, where you link another record or view them all.
- **Roles on a link.** Say what a linked person is to a deal, such as the one who signs. Up to 25 roles to a relationship.
- **Filter and add up.** Filter visits by a property of their customer, and count or total a customer's visits on the customer.
