What are the payment terms?

Our usual payment method is TT (Telegraphic Transfer) upfront, followed by a 30% deposit before production begins. The remaining 70% balance is due before shipment after production is complete.

How do you provide after-sales service?

We adhere to the concept of 'one-time cooperation, lifelong service,' providing full lifecycle technical support and guarantees. We have a professional technical team to assist clients with remote debugging.

AI-Powered supplier vetting

SummaryThe supplier presents itself as an integrated manufacturer with independent control from R&D and design through production and delivery. It reports 15 years of industry experience, an approximately 8,000-square-meter production base, fully automated equipment, OEM/ODM and sample/design customization, and CE/RoHS certification. It also reports serving thousands of retail terminals across five continents and providing pre-sales, installation, and after-sales support. However, the evidence identifies important limitations: no available SDK, no new products in the past year, no in-stock, overseas warehouse, overseas showroom, overseas agent/branch, or offline trade-show capability, and no valid manufacturing-capacity contract with related subcontractors. Service-capability assessment and corrective-action procedures lack written records. Financial information is present only as year labels, so financial strength cannot be assessed.

Supplier typeThe supplier is presented as a manufacturer with a modern production base, automated equipment, and independently controlled activities spanning R&D, design, production, and delivery. Its stated OEM and ODM services further support classification as an integrated OEM/ODM manufacturer.

CertificationsThe supplier explicitly states that its products are certified by EU CE and RoHS and meet international standards. This provides direct evidence of certification-related export compliance, although no certificate numbers or validity details are provided.

Production capacityThe supplier reports large-scale production, intelligent and fully automated equipment, an approximately 8,000-square-meter production base, and average peak- and off-season lead times within 15 workdays. Countervailing limitations include no in-stock capacity and no valid manufacturing-capacity contract with related subcontractors, so production capability is evidenced but capacity resilience and subcontractor governance are not fully established.

Customization capabilityThe supplier explicitly offers industry-leading OEM and ODM services, including customization from samples and designs, to support personalized and branded products. This directly demonstrates both manufacturing and design-based customization capability.

Client casesThe supplier states that it has 15 years of industry experience and has served thousands of retail terminals across five continents. These are explicit scale and geographic experience claims, although no named customers, project details, or independently verifiable case records are provided.
