For most Amazon and e-commerce sellers, the Proforma Invoice (PI) is the final document you receive before pulling the trigger on a wire transfer. It’s also the exact moment when most sourcing scams occur.
While Alibaba’s Trade Assurance provides a safety net, savvy “ghost factories” and brokers have found clever ways to bypass those protections using the PI. Before you send your hard-earned capital across the ocean, check your invoice for these five critical red flags.
1. The “Beneficiary Name” Doesn’t Match the Company Name
This is the single most common red flag in Chinese manufacturing. If you are dealing with “Ningbo Electronics Co., Ltd” but the bank account name on the PI is “HK Jinxing Trading Limited” or, even worse, a personal name like “Zhang Wei,” stop immediately.
The Risk: Legitimate factories in mainland China have corporate bank accounts that match their registered business license. If the name is different, you are likely paying a middleman or a “hidden” broker. If the factory disappears, your money is gone, and Alibaba may not be able to help because you paid an entity that isn’t on the contract.
2. The “Official Chop” Looks Digitally Altered
In Chinese business culture, the Red Chop (Seal) is more legally binding than a signature. Every legitimate PI should be stamped with the company’s official round red seal.
The Red Flag: If the stamp on your PI looks perfectly horizontal, or the ink is the exact same shade of red throughout, it’s likely a digital “copy-paste” job in Photoshop.
The Test: Look for the small imperfections or “bleed” from a real ink stamp. If it looks too perfect, the person sending the invoice might not even be in the factory office—they might be a freelancer operating from a laptop.
3. Sudden Changes to Banking Details
You’ve done a sample run, everything went well, and now you’re ready for the bulk order. Suddenly, your contact tells you: “Our main account is under audit. Please send payment to our subsidiary branch instead.”
The Risk: This is a classic “Business Email Compromise” (BEC) scam. Either your supplier’s email has been hacked, or a rogue employee is trying to divert funds to a private account before quitting. Never accept banking changes via email or a PDF update without secondary verification through a tool like FactoryVet.
4. Generic or Incomplete Factory Addresses
Legitimate manufacturers are proud of their facilities. A professional PI should list a detailed physical address, including the province, city, district, and building number.
The Red Flag: If the address is just a suite number in a high-rise office building in a city like Shenzhen, you are almost certainly dealing with a trading company, not a factory.
Why it matters: Trading companies add a 10–30% markup. More importantly, they have no control over quality. If the actual factory messes up your order, the trading company has zero power to fix it.
5. Inconsistent “Unit Price” vs. The Alibaba Quote
Some sellers are so focused on the total “Grand Total” that they miss subtle changes in the line items.
The Red Flag: Watch for “hidden” fees that weren’t in your initial negotiation, such as “Handling Charges,” “Export Documentation Fees,” or a slight increase in the unit price of raw materials.
Pro Tip: Scammers often use the PI to “test” a buyer. If they can sneak an extra $200 onto the invoice and you don’t notice, they know they can exploit you further during the production phase.
The Bottom Line
A Proforma Invoice is more than just a bill; it is a legal snapshot of the company you are about to go into business with. If any of these details feel “off,” it’s time for a deep-dive audit.
Don’t wire money on a gut feeling. Use the FactoryVet Registry Search to triangulate the factory’s legal standing, litigation history, and registered capital before you pay. A $29 audit could save you $29,000.
