What is sourcing service?

Sourcing service refers to the process of identifying, evaluating, and partnering with the right manufacturers to ensure product quality, cost-efficiency, and on-time delivery.

With over 20 years of experience in manufacturing consumer electronics, EILI is not only a trusted OEM/ODM supplier but also a reliable sourcing partner — helping clients quickly connect with qualified factories in Vietnam, China, and Cambodia.

We manage the end-to-end sourcing process — from factory identification and qualification to price negotiation, sampling, quality inspection, and production tracking — to ensure smooth, efficient, and reliable supply.

Why Choose EILI’s Sourcing Services?

Not just a broker — we’re an experienced manufacturer.

Unlike pure sourcing agents, EILI brings over 20 years of hands-on manufacturing experience in the consumer electronics (CE) industry. We understand materials, SMT processes, voltage testing, performance validation, and certifications such as CE, FCC, and RoHS. Our in-depth knowledge of manufacturing risks helps us select the right factories, inspect the right checkpoints, and ensure your final products meet every requirement.

 

Our Sourcing Advantages

Transparent process with tight quality control

From factory assessment and sampling to quality checks and production tracking, our sourcing workflow is transparent and actively managed by on-site personnel. We provide regular progress updates to clients throughout every step.

Factory-matching based on actual production capabilities

We only work with verified factories that hold certifications and have a strong track record in CE manufacturing. Not every supplier can handle precision aluminum unibody casting, multilayer PCBA production, or achieve 10Gbps data transfer speeds.
 EILI evaluates factories based on:

  • SMT capability & incoming component QC
  • Housing & surface treatments (anodizing, painting, hairline texture…)
  • Test equipment: high-load, aging, ESD, drop test, etc.
  • Certifications: ISO9001, BSCI, CE, FCC, RoHS, REACH

Multi-level quality control – tailored to CE standards

Safety is our standard, not an option.
 We implement custom QC processes per product type, following IQC, PQC, FQC, and OQC protocols. Third-party inspections (SGS, BV…) can also be arranged.
 Examples:

  • Hubs & Adapters: Real power output test, auto voltage regulation, thermal check under full load 
  • PSSD & Card Readers: Read/write speed test, OS compatibility validation 
  • Laptop Stands: Mechanical durability, passive cooling performance with live electronics 

Power Banks: Battery cell safety, charge-discharge efficiency, thermal and current stability under continuous use

OEM/ODM engineering cost optimization

 Beyond ready-made products, EILI helps you optimize design and cost from the ground up:

  • BOM optimization to reduce cost without sacrificing performance
  • Packaging and mechanical structure design for easier assembly and inspection
  • Technology recommendations to make your product stand out in the market
