From First Call to First Container — We Manage Every Step

- Design assets: reference images, samples, or mockups
- Project scope: target quantity, budget, and timelines
- Compliance: destination-specific safety and quality standards
- Packaging specs: branded labels, boxes, and inserts
02
Factory Search & Supplier Screening
We tap a vetted network of 450+ factories across Shenzhen, Guangzhou, Yiwu, and Ningbo — shortlisting manufacturers that match your category, volume, and quality bar.
- Comparison sheet: 3–5 pre-screened factories with profiles, MOQ, lead times
- Background check: business registration, export history, ISO certifications
- Capability review: equipment, capacity, and quality track record

Why LeelineGroup
What makes us different from every other sourcing option
You're not just hiring a sourcing vendor — you're gaining a strategic partner embedded in China's manufacturing ecosystem, working exclusively in your interest.
Transparent Pricing, No Hidden Costs
Every cost is broken down upfront — unit price, packaging, inspection fees, shipping, and customs. Factory quotes are shared directly with you. No guessing where your money goes and no surprise markups buried in the final invoice.
- • Clear payment terms with zero hidden fees
- • Itemized cost breakdown before you commit
- • Direct access to factory pricing — no middleman markup
Local Team on the Ground
Based in China, our team conducts in-person factory visits, communicates with manufacturers daily, and monitors production in real time. Speaking the language and understanding local business practices means problems get solved on the spot — not over email two weeks later.
- • On-site factory inspections and audits
- • Deep knowledge of local manufacturing practices
- • Same-day problem resolution in Mandarin and English
Flexible MOQ — Start Small, Scale Smart
Whether you need 500 units or 50,000, MOQ is negotiated to fit your business stage — not the factory's preference. Warehouse stock options are available so large upfront commitments aren't required to get started.
- • Negotiated MOQs that fit your business stage
- • Warehouse stock options for faster fulfillment
- • Scalable order structure as your business grows
OEM & Full Customization Services
From logo printing to custom packaging, instruction manuals, and branded inserts — we handle complete localization. Your sourcing includes everything needed to launch a differentiated brand, not just generic products.
- • Logo and branding customization
- • Custom packaging design and printing
- • Localized instruction manuals and labels
- • Full white-label capabilities
Supplier Discovery
Multi-Channel Supplier Discovery
We source from every major Chinese supplier platform — plus offline factory networks most buyers never access.
Generic products compete on price. Private label brands compete on value — and win.
From custom logo and packaging design to localized instruction manuals — we handle the entire customization process from factory to final delivery, so you launch a brand, not a commodity.
Client Results
Brands that trust their supply chain to LeelineGroup
“Quality control used to cause me constant anxiety. Now, having a dedicated local team on the ground changes everything. I receive real-time updates, factory videos, and rigorous AQL inspection reports before any shipment. Their inspector caught a packaging color discrepancy early and fixed it instantly. We haven't had a single defective batch reach our Amazon FBA inventory since starting this partnership.”
Matthew S. Majeski
Amazon FBA Seller
“Transitioning from generic white-label items to a recognized private label brand seemed impossible. Coordinating custom die-cut packaging and multi-language manuals across three suppliers was overwhelming. This sourcing team stepped in, managing the entire OEM localization process seamlessly. They ensured the golden sample exactly matched mass production. Our unboxing experience is premium now, and customer retention has doubled.”
Ruby F. McNabb
DTC Brand Founder
“LeelineGroup transformed our sourcing from a constant headache into the smoothest part of our business. Our margins improved 22% in the first year working with them. The single-point-of-contact model means I'm never repeating myself or chasing down updates across time zones.”

FAQ
Product sourcing questions, answered directly
How does your quality control process work?
Quality control is applied at three stages — incoming material inspection, mid-production check, and final pre-shipment inspection. AQL international sampling standards are used at each checkpoint. Detailed reports with photos and defect logs are sent to you after every inspection. No shipment is approved until the product meets your exact specifications. If issues are found, corrections are made before goods leave the factory.
How long does the sourcing and production process take?
A typical timeline is 4–8 weeks from initial brief to production start. Spec confirmation takes 3–5 days, supplier matching and vetting 7–14 days, sampling 10–21 days depending on product complexity. We'll give you a detailed timeline during the assessment phase, and complex products may take longer.
What information do I need to provide to start a sourcing project?
Share your product specifications (materials, dimensions, desired features), target quantity, budget range, and timeline. Reference images, samples, or competitor product links help enormously. If you have specific certifications required for your market (CE, FDA, RoHS), let us know up front. The more detail you provide, the faster we can match you with the right factory.
What's the minimum order quantity (MOQ)?
MOQs vary by product category and factory, but we typically negotiate flexible terms starting as low as 100–500 units per SKU. Our warehouse stock options also let you start with smaller volumes while benefiting from bulk pricing. We'll always find the right match for your volume.
What payment methods do you accept?
We accept PayPal, credit cards, Wise, and bank transfers. Payments are structured by milestone — deposit to start, progress payments tied to QC checkpoints, and balance before shipment. This protects your funds throughout the production cycle.
How is LeelineGroup different from using Alibaba directly?
Alibaba gives you a directory — LeelineGroup gives you a supply chain department. We pre-vet every factory on-site before you see them, negotiate on your behalf, conduct multi-stage QC, and handle all logistics. One dedicated specialist manages your entire operation instead of you managing dozens of supplier relationships yourself.
