Purchase Steps
What are the steps to purchase from Zener?
Step 1: Needs Assessment and Solution Proposal
Our technical experts begin by understanding the customer’s specific power requirements, operating environment, and long-term goals. Based on this assessment, we recommend the most suitable products and system configurations tailored to the client’s needs.
Step 2: Purchase Request and Quotation Preparation
Once the customer expresses interest in a particular solution, we formally receive their purchase request. In response, we prepare a detailed price quotation covering the proposed products and services.
Step 3: Proforma Invoice Issuance
Following the quotation phase, a proforma invoice is issued for the selected items. This document outlines all financial and logistical details necessary for the customer to proceed with the purchase.
Step 4: Confirmation and Payment Agreement
Upon the customer’s approval of the proforma invoice, both parties finalize the payment terms, including method, schedule, and any applicable conditions. This step confirms mutual agreement and initiates the order process.
Step 5: Procurement and Final Invoice
After confirming the order, our team begins the procurement process for the approved items. Once ready, we issue the final invoice to the customer based on the agreed terms and confirmed specifications.
Step 6: Delivery, Warranty, and Handover
The final step includes preparing the goods for delivery, issuing official warranty documentation, and ensuring all contractual obligations are met. The products are then handed over to the customer in accordance with the agreed timeline and conditions.
