Disclosure: Yiwu Lian has a commercial interest in introducing SUPROOF. This article is an educational guide and service introduction, not an independent review or a guarantee of any transaction outcome.
"Check this company" can describe several different needs: confirming a legal identity, reviewing document inconsistencies, observing a physical operating site, or inspecting a specific shipment. If the question is defined incorrectly, even a good report may not answer what the buyer actually needs.
Before choosing a service, identify the uncertainty you want to reduce.
1. Digital company check: start with identity and available records
When you are comparing several suppliers, the first questions may concern the legal company name, registration details, or consistency between basic company information and the documents you have.
SUPROOF currently presents a digital company profile as an initial screening option. The result should be read within the limits of the available information and the selected service. A digital check is not the same as physically observing a factory, testing a product, or confirming production capacity for a specific order.
For a useful digital review, prepare the Chinese legal name, company identifier when available, and the documents supplied by the seller. If you are not sure which legal entity is actually selling to you, resolve that identity question before collecting large amounts of data about the wrong company.
2. Human review: useful when the evidence does not line up
Sometimes basic information exists but the pieces are inconsistent. The invoice issuer may differ from the company introduced by the salesperson. The production address may be unclear. A payment beneficiary may not match the contract party.
In those cases, the task is not simply to collect more data. The evidence needs to be compared, the relationship between entities needs to be clarified, and unresolved questions should be made explicit.
SUPROOF's public service descriptions and terms refer to evidence analysis and human-reviewed conclusions for certain services. Before ordering, confirm whether your specific question is included in the selected scope. "Human review" does not automatically mean an on-site factory visit.
3. Factory visit: answer questions about physical presence and operations
If the main question is about a production location, visible equipment, or activity at a stated address, remote document review cannot provide the same evidence as an on-site visit.
Before requesting a visit, define the exact address, the product, the questions to be checked, access requirements, and the type of output you expect. Availability should be confirmed for the specific city, site, and scope.
SUPROOF service policy:

The existence of an on-site option should not be interpreted as guaranteed immediate coverage of every city or every factory. Scope and feasibility need to be confirmed separately.
4. Product inspection: focus on a specific shipment and acceptance criteria
If production is complete and your question is whether the goods ready for shipment match the order, you are dealing with a product-inspection problem rather than only a company-identity problem.
Define the technical specification, quantity, packaging requirements, approved sample, acceptance criteria, and reporting method. A factory visit does not automatically confirm the quality of every unit produced there.
If specialist laboratory testing is required, clarify the test standard and the qualification of the testing provider separately. A company-information report should not be presented as a product conformity certificate.
5. A simple example of how the scope can change
Imagine that you are buying an industrial component. At first, you do not know which legal company issued the proforma invoice, so the problem is identity matching. Later, you learn that the seller and manufacturer are different companies, so the next problem is understanding their relationship and the production location.
When the goods are ready, the question changes again: do the dimensions, quantity and packaging match the agreed order?
One fixed check does not fully answer all three stages. This is a hypothetical training example, not a real Yiwu Lian or SUPROOF case.
6. Clarify five things before paying for a verification service
What is your main question?
What information and documents will you provide?
What exact output will you receive?
What is outside the selected scope?
What still needs confirmation about timing and price?
Record the answers for that specific order. A package name alone is not enough to define the work.
Current pricing and order terms should always be checked directly with the service provider. This article does not state a fixed price or guaranteed turnaround time.

The right verification scope should answer a defined question. No single check, visit, or inspection can guarantee a risk-free transaction.
