A practical guide to deciding when to verify, pause or stop before payment
Written and reviewed by KAN, Owner of Anhui Gangya Construction Machinery Sales Co., Ltd.

This guide is based on KAN’s direct experience with overseas buyer requirements, current machine evidence, live video calls, buyer-appointed inspections, PI terms and payment checks in used-equipment export transactions.

Quick Answer: Which Red Flags Should Stop a Payment?
Pause payment when important information cannot be kept consistent or reasonably explained.
Examples include a model that does not match the machine identity, repeated refusal to provide current evidence, unexplained quotation changes, or an account name that does not match the PI seller.
One unusual detail does not prove fraud. If important evidence remains unavailable or payment details change unexpectedly, pause until the transaction is independently reconfirmed.

Final Pause-Payment Checklist
Red Flag Matrix: Verify, Pause or Stop
Level 1 — Verify
Examples:
One requested photo is missing
A new video needs time to arrange
The machine is working on a jobsite or stored elsewhere
Buyer action:
Ask for an explanation and review the promised evidence.
Level 2 — Pause Payment
Examples:
The quoted model and machine identity do not match
Only old photos or videos are repeatedly provided
Reasonable requests for current evidence are avoided
Important attachments or preparation work are missing from the PI
The beneficiary account name does not match the PI seller
Buyer action:
Do not transfer funds yet. Request current evidence, a clear explanation and corrected documents.

Level 3 — Stop and Independently Reconfirm
Examples:
Payment information changes unexpectedly
Several important details conflict at the same time
Reasonable verification is repeatedly refused
The buyer is pressured to pay before questions are resolved
Buyer action:
Stop the transfer and reconfirm the company, machine, PI and account information through verified contact methods.
Machine Identity Does Not Match the Offer
Compare the quotation with:
Machine plate
Model information
Visible configuration
Current photos and videos
Small naming differences may be explainable because some models use different market names or suffixes. The explanation should still be clear and supported by evidence.
Pause payment when:
The quotation shows one model but the plate shows another
Photos appear to show different machines
Visible configuration does not match the written offer
The supplier cannot identify which machine is being sold
A machine plate is an important reference, but it does not prove complete condition or show that every photo and video belongs to the same machine.
Current Photos or Live Video Calls Cannot Be Arranged
A supplier may need time to arrange photos, a working video or a live video call.
The excavator may be working on a jobsite or stored elsewhere. That does not automatically prove fraud.
Concern increases when:
Reasonable requests are repeatedly avoided
Only old photos or videos are provided
The machine’s location cannot be explained
No current verification can be arranged
A live video call can connect the supplier, machine location and current evidence in real time.
Refusing every reasonable request for a live video call deserves serious attention, but it does not automatically prove fraud. A machine may be outside the supplier’s yard. What matters is whether the location can be explained and current evidence or a later live video call can still be arranged.
The Quote Is Unclear or Changes Without Explanation
An unusually low price is not automatically proof of fraud, but it is rarely a free gift.
A lower quotation may reflect machine condition, included attachments or preparation scope.
Risk increases when a very low price is combined with unclear identity, missing current evidence, unexplained changes or payment pressure.
Pause when:
The written offer changes without explanation
Promised attachments disappear
Preparation work is mentioned only in chat
Important terms are missing from the PI
Payment Account or Communication Details Suddenly Change
Even when machine evidence looks credible, verify payment instructions separately.
The beneficiary account name should normally match the seller company named in the agreed PI.
Pause when:
The account name does not match the PI
The account changes unexpectedly
New payment details arrive without updated documents
Any alternative arrangement should be explained, documented and independently reconfirmed before payment.
Do not rely only on a new WhatsApp message, email address or phone number.
Shipment and Document Information Is Missing
Before payment, understand what final records can be provided and when.
Ask about:
Final machine photos or video
Attachment confirmation
Preparation or dismantling status
Loading photos or video
Agreed export documents
The timing should be explained, and the machine, quantity, buyer and destination details should remain consistent across the agreed records.
What Buyers Should Do When a Red Flag Appears
Step 1 — Identify the Exact Inconsistency
Write down what does not match:
model, plate, video, quotation, PI, account name or shipment information.
Step 2 — Request Specific Evidence or Correction
Ask for the exact item needed:
photo, new video, live video call, explanation or updated document.
Step 3 — Compare the New Information
Check whether the explanation resolves the issue without creating new contradictions.
Step 4 — Pause Payment if the Issue Remains Unresolved
Do not let payment pressure replace verification.
Step 5 — Independently Reconfirm Higher-Risk Changes
Use verified contact details, buyer-appointed inspection or another independent source.

Frequently Asked Questions
Does refusing a live video call prove that a supplier is a scammer?
No. The machine may be outside the supplier’s yard. Concern increases when live viewing is repeatedly refused, the location is unexplained and no other current evidence is provided.
Does a very low excavator price prove fraud?
No. A low price needs explanation, but concern increases when it is combined with unclear machine identity, unavailable current evidence or inconsistent payment information.
Should the beneficiary account name match the company in the PI?
The account name should normally match the seller company in the PI. If it does not, pause payment, request a written explanation and independently reconfirm the arrangement.
What should I do when the quotation and current video do not match?
Pause payment. Ask the supplier to identify the exact machine, provide updated evidence and correct the documents before continuing.
Experience and Responsibility Notes
This guide is based on KAN’s experience with overseas buyer requirements, machine evidence, live video calls, PI terms and payment checks in used-equipment transactions.
This guide does not provide legal, banking or fraud-investigation advice.
A red flag is a reason to verify, pause or independently reconfirm. It is not automatic proof of fraud.
