Is the company real?Identity, ownership and operating footprint.

Is the person authorized?Role, corporate connection and authority.

Is it really a manufacturer?Factory, trader or intermediary — and what that means.

Can it actually perform?Technical, production, supply and delivery capability.

Do contract and bank details match?Seller, invoice issuer, beneficiary and payment relationship.

What must change before payment?Evidence, inspection, milestones and transaction controls.

For Complex & High-Value Transactions

When the deal becomes more complex, we follow the evidence across the entire commercial chain.

For commodities and other high-value transactions, a company check is only the beginning. We connect counterparty, cargo, documents, logistics, banking, title and payment into one evidence-based structure.

Counterparty→Authority→Cargo→Documents→Logistics→Banking→Title→Payment

Why Ordinary Checks Miss Risk

Most verification stops at “the company exists.” We keep going.

ZERUI TRANSACTION REVIEW

Company → Person / Authority → Capability → Goods → Documents → Payment → Title / Control → Delivery

We test whether the facts belong to the same transaction and whether the structure can be safely executed.

Claimed Structure vs. Evidence-Based Structure.

The gap between them is where transaction risk often hides.

What You Receive

Not just information. A decision you can use.

Our output separates verified facts from unresolved issues, identifies material contradictions and tells you what evidence or structural change is required before proceeding.
