# Address book

> Manage customers, suppliers, addresses, and contact details used by receiving and orders.

The address book stores trading partners. Customers feed [orders](/orders). Suppliers feed [receiving](/receiving), [documents](/documents-qa), and [QuickBooks setup](/quickbooks-setup).

## Customer records

Customers represent buyers, distributors, retail accounts, or internal destinations that receive finished goods. A customer can have multiple addresses.

Use customer records when:

* Creating a sales order.
* Importing open orders.
* Mapping customers to QuickBooks.
* Searching shipment history during support or traceability work.

## Supplier records

Suppliers represent ingredient, packaging, or service providers. Approved suppliers can be tied to received lots, supplier documents, and item-supplier relationships.

Use supplier records when:

* Receiving a supplier lot.
* Tracking supplier lot codes and COAs.
* Reviewing supplier documents.
* Mapping vendors to QuickBooks.

## Address records

Addresses can be imported or created manually. Blank labels default to `Default` during import. Keep labels practical, such as `Ship to`, `Billing`, `Receiving dock`, or `Warehouse`.

| Address type     | Used by                                               |
| ---------------- | ----------------------------------------------------- |
| Customer address | [Orders](/orders), shipments, customer communication. |
| Supplier address | [Receiving](/receiving), supplier context, QA review. |

## Importing address book data

Address book imports use these files:

* `customers.csv`
* `suppliers.csv`

See [CSV imports](/imports) for required columns, example files, and validation rules.

## Common issues

* Repeat customer or supplier names when one company has multiple addresses, but keep company-level fields consistent across those rows.
* Address labels must be unique per customer or supplier within the same import.
* A supplier that is not approved may still exist, but teams should treat approval state as a QA and purchasing signal.
