Build a complete item list
Include product names, part numbers, quantities, units and any preferred brands. Add drawings or reference photographs when available.
State the documentation needed
Mention any certificate, datasheet or inspection requirement at the enquiry stage. Availability and scope should be confirmed in the quotation.
Agree the commercial details
Ask for availability, delivery timing and payment terms. A submitted enquiry is a request for quotation; it does not confirm stock or place an order.
