Purchase Steps
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.

Product Originality

At Zener Eng. Co., we understand that today’s smart buyers seek original, high-quality products those manufactured by reputable, well-established companies that invest in research, development, and quality assurance. We fully respect this expectation and are committed to offering only genuine products, with full guarantees of authenticity and performance.
Driven by our core values of honesty and customer-centric service, we go to great lengths to ensure that every product we offer is authentic, officially sourced, and backed by valid warranties. All items are verified with original manufacturer serial numbers, untampered, and legally imported into the country.
The equipment and devices we supply are fully covered under warranty. In the event of any issue during the warranty period, our customers benefit from full after-sales support and technical service provided by Zener Engineering Company.
Customer satisfaction is a fundamental organizational goal for us. We constantly measure our success in this area through feedback and experiences shared by our valued clients.
Unfortunately, it is not uncommon for buyers to encounter sellers who promise originality and official warranties, only to discover when problems arise that the product was not genuine or the warranty was invalid. This leads to frustration and a lack of trust in the purchasing process.
At Zener, one of our key missions is to eliminate such concerns by creating a sense of trust and peace of mind for our customers. We want you to feel confident in every purchase you make with us. To that end, we are always ready to provide official documentation verifying the authenticity and origin of any product upon request.
