What you dread about a sourcing agent

We took your worst fears.
We flipped them.

The agent takes a hidden commission from the factory
→
A price negotiated directly with the factory and confirmed in writing before you order.
You pay without ever seeing what you get
→
Video and photos of the product before you settle the balance.
Quality defects surface only once the goods arrive
→
Inspection before shipping. If it isn't compliant, we hold the departure — not your cash.
What we do

The whole import, without getting your hands in the engine.

Product sourcing in China
We identify and vet reliable suppliers for your product — not the first one on Alibaba. Negotiation, verified samples, MOQ matched to your real volume.
Quality control
On-site pre-shipment inspection, with a photo and figures report sent before the container leaves — not after the problem reaches you.
Logistics China → world
Sea, air and express freight, customs included. We handle factory → port → customs → your warehouse, with tracking.
Private label & own brand
Custom product development, packaging and branding. From design to delivery at your door or straight to Amazon FBA.
Dedicated sourcing agent
One French/English-speaking contact who travels on-site — not a switchboard or chatbot. Order tracking, dispute handling, honest reporting even when things go wrong.
Storage & prep
Storage in China, consolidation of several suppliers, prep and labelling before a grouped shipment. You never touch the stock.
Beyond sourcing
From factory to brand
Beyond the product: design, packaging and a Shopify store to turn your import into a sellable brand.
  • Product designWe shape the product and its visual identity, not just its manufacturing.
  • PackagingPackaging that makes people want to buy and holds the premium promise.
  • Shopify storeThe online store that converts, ready to take your first sales.

How it works

Three steps. You approve each one.

02
We source & inspect
Negotiation, samples, production follow-up and on-site inspection. Video and report before any departure — you approve before paying the balance.
03
We ship & deliver
Freight, customs clearance and delivery to your warehouse. One contact from start to finish, reachable 7 days a week on WhatsApp.

Frequently asked

Before you write to us.

What is the minimum budget to work with SINVEX?

There is no single figure: the right budget depends on the product, the volume and the destination. Our clients range from test orders of a few CBM shipped LCL to full containers. What matters is that your project stays profitable once every real cost is included: sourcing, quality control, freight, customs and taxes.

If your budget is too tight for an import to make sense, we tell you on the first call, free of charge. For a first import, we almost always recommend starting small, with a sample and then a test order, before moving to a full container once the product and supplier are validated.

How do I know I can trust you with my money?

That's the right question to ask any sourcing agent — and the honest answer is that trust is built in stages, not on a promise. You stay in control: you validate every supplier, every sample, and every payment, never us on your behalf.

We negotiate a firm price before any order, confirmed with you in writing. That price doesn't move once production starts — no surprise costs discovered later, no renegotiation mid-way. For a first project, we always recommend starting small — a sample, a test order — before committing a significant volume.

We remain a human-scale operation: that means a direct, responsive point of contact, not a marketing claim. If a question is left without a clear answer before your order, it's not on you to trust us — it's on us to earn it.

What happens if the goods are defective or non-compliant?

This is exactly why quality control happens before shipping, not after you receive the goods. Our pre-shipment inspections check a statistical sample of your order against your specifications, with a detailed photo report sent before the container leaves China.

If a non-conformity is detected at this stage, we hold the shipment and negotiate with the supplier — rework, replacement, or discount — before you've paid the balance or the goods are at sea. It's far easier to resolve in China, with an agent on the ground, than once the container has reached you.

How long between my request and my product being delivered?

After qualification, a proposal or detailed feedback is sent to you within 48 business hours, depending on the scope of the project. After that, lead time depends on your product: usually 2 to 4 weeks of production (depending on complexity and MOQ), then 30 to 45 days of sea transit depending on route and port, or 5 to 10 days by air, plus customs clearance.

For a first sea-freight order, allow 2 to 3 months on average between supplier validation and delivery. Lead times shrink considerably for later orders, once the supplier is validated and production runs smoothly.

I'm based outside France — can you still help me?

Yes. We operate at the crossroads of Asia, Europe, Africa and Pakistan. Examples on this site often use France for illustration, but we handle a range of corridors: China → Europe, China → UAE, China → Africa, China → Pakistan.

The principle stays the same regardless of your destination — supplier audit, quality control, freight, customs — only transit times and costs vary. Tell us your destination and we'll give you a tailored pricing grid.

What is the difference between you and Alibaba or a freelance agent?

Alibaba connects you with a supplier; we verify that supplier, negotiate on your behalf, monitor production, and manage all logistics through to delivery. A freelance agent can handle part of this work, but rarely with the same level of commitment to a firm price or the same responsiveness when something goes wrong.

Our value isn't limited to sourcing: it's the combination of sourcing + quality + logistics under a single point of contact, with honest reporting, which avoids the classic friction between multiple providers passing the blame when something goes wrong.

If I'm not satisfied with the quote or the service, am I committed?

No. The first qualification call is free and non-binding: it helps us understand your project and tell you honestly whether we can help. Supplier research and comparison start with the sourcing study, whose scope, timeline and price are confirmed in writing before any work begins.

Our goal is for you to work with us because the service fits your need, not because you're locked into a contract. This is also why a firm, confirmed price remains our standard at every stage, not just at the start.
