SourciaVera is a third-party team in Guangzhou working for the buyer, not the factory. We supervise factories in China in English and Spanish: on-site visits, unedited video and a written report. Pre-shipment inspection is $399 per day, factory audit $499 per day. No factory commission.
An initial audit confirms the factory exists and has real capacity. It doesn't guarantee that actual production, weeks later, matches what was agreed.
The most costly problems — undisclosed material substitutions, unreported subcontracting, quality defects — usually show up during production, not before it.
That's why "supervising" a supplier in China means something different from simply verifying them once: it means having someone on the ground, in person, throughout the entire process. For a quick look before you commit, a live video factory verification ($120 per hour) shows a factory floor in real time.
An audit answers "can they manufacture what they promise?" Supervision answers "are they manufacturing what we agreed on, right now?"
| Feature | One-Time Audit | Continuous Supervision |
|---|---|---|
| When it happens | Once, before production | Throughout the entire manufacturing cycle |
| What it catches | Supplier capacity and legitimacy | Deviations during actual production |
| Question it answers | Can they manufacture what they promise? | Are they manufacturing what we agreed on? |
| Ability to intervene | No — it's a snapshot in time | Yes — corrected in real time |
| Outcome | Initial fitness report | Periodic reports + active intervention |
| When it's enough | First evaluation of a new supplier | High-value orders, complex products, long production cycles |
We confirm the supplier is a real manufacturer — not a middleman — by reviewing licenses, legal structure, and installed capacity.
Periodic visits to the production line to confirm manufacturing matches spec, catch deviations early, and avoid surprises at the end.
Physical presence during loading to confirm the complete, correctly packed order is what actually ships.
For large orders or new suppliers, we thoroughly evaluate processes, quality control, and compliance before committing to production.
We confirm the supplier's legitimacy before any payment.
We define which production stages we'll visit the factory for, based on the order's risk level.
Our team in Guangzhou visits the factory physically, not over a video call.
You receive a report in English and Spanish after each visit, with photos and findings.
Production errors are cheap to fix early — and very expensive to fix at the end. That's why we define specific control points on every order.
We verify the materials entering the line match the agreed specifications — composition, gauge, origin. This is the first point where undisclosed substitutions happen, and the cheapest to correct before the material is processed.
We review the first unit produced before mass production starts. If there's a mold, spec, or assembly error, it can be corrected here without the cost of reworking the entire batch.
Sample review at 50% of the order already manufactured. Confirms consistency between the start and midpoint of production — catches cumulative quality drift before it affects the full order.
Final check before the order leaves the factory: unit count, packaging integrity, labeling, and confirmation that what goes into the container matches the agreed order exactly.
We publish our prices — no need to call just to find out.
SourciaVera verifies Chinese factories on the ground — no stock photos, no self-reported claims. We visit in person, review licenses, and confirm production capacity before you send a deposit.
Whether you need a one-time verification, a full audit, or continuous supervision during production, we handle it in English and Spanish — so nothing gets lost in translation.
