Customer Classifications
Simple groups you can create to categorize customers (e.g. VIP, regular retail, partners), used for filtering and reporting — they don't affect pricing or accounting logic (that's driven by Customer Type, not classification).
Go to Customers & Suppliers → Customer Classifications and click Create:

Fields
- Name: (required).
- Active: (toggle) inactive classifications don't appear in the classification picker when adding/editing a customer.
Notes
- Classification is entirely optional per customer, and there's no default.
- To set the price tier (wholesale/semi-wholesale/retail), use the Customer Type field on the Customers form — it's independent of classification.
