A complete order specification reduces revisions and makes production, inspection, and delivery easier to control. B2B buyers can use the following checklist before issuing a purchase order.

Product and application

Record the selected model, application, system power, usable capacity, voltage range, expected cycles, operating temperature, installation method, and quantity. Attach the approved specification or technical agreement to the order.

Customization scope

List every requested change, including communication protocol, enclosure, connectors, labels, logo, color, manual, packaging, accessories, and spare parts. Refer to approved drawings and artwork by version.

Inspection and documents

Confirm the required inspection records, test reports, packing list, commercial documents, manuals, wiring information, and any market-specific documents agreed for the project. Special acceptance requirements should be defined before production begins.

Packing and logistics

State the destination, trade terms, shipping method, labeling needs, pallet or case requirements, lifting and handling restrictions, and delivery contact. Battery shipments require early coordination of transport documentation and carrier requirements.

After-sales responsibilities

Agree on the warranty basis, technical contact, response process, installation responsibility, remote support conditions, spare-part handling, and evidence required for a service request. Keep serial numbers and commissioning records for future follow-up.

Before payment and production, both parties should confirm one final commercial and technical version. This becomes the reference for manufacturing, quality inspection, shipment, and after-sales support.
