The Suppliers area in the administration bundles all master data and settings around supplier administration — settings, industry sectors, categories and additional attributes. Suppliers are used in ZEP for receipt entry with external receipt reference. Reachable via the main menu under Administration > Suppliers.

The settings page bundles the behavior around suppliers — automatic supplier number assignment, default values for new suppliers and configuration of the supplier list. Changes affect all existing and future suppliers and affect the daily work of all employees recording receipts with supplier reference.

This master data enables flexible structuring of suppliers — analogous to customer classification. It works across suppliers and is the basis for supplier-related receipt reports.

List of industry sectors that suppliers can be assigned to. Per supplier, one or more industry sectors can be maintained, which appear as filters in supplier and receipt reports. Industry sectors can be maintained separately from the customer industry list or use the same master data source.

Multi-assignable categories for classification of suppliers — for example service type, region or contract status. Appear as additional filters in the supplier list and receipt reports. Useful for separating sub-suppliers, fee-based invoicers or external service providers with different billing modalities.

Freely definable additional fields that appear in the supplier mask as additional input fields. Per attribute, designation, data type and mandatory field property can be maintained. Additional attributes are suitable for data not covered by standard supplier fields — for example supplier IDs from external accounting systems or industry-specific classifications.

Suppliers appear primarily in receipt entry — detail documentation on receipt entry with supplier reference is part of Revenues and costs. Industry sectors and categories additionally filter the revenue reports and can be used in Invoicing for supplier-related reports.
