How to Read a Sanity Pro Forma Invoice

You've negotiated a price of $2.40 per unit for 5,000 LED bulbs on Alibaba, the supplier sends over a PDF stamped 'Pro Forma Invoice,' and you're about to wire a 30% deposit. But if you don't know how to read a sanity pro forma invoice, you could be wiring money against a document that hides a $1,800 mold fee, a 5% 'bank charge,' or a spec that says 9W instead of the 12W you agreed on. A pro forma invoice is not a real invoice — it's a pre-payment quotation that becomes the blueprint for your entire order. Reading it correctly is the difference between a smooth container and a costly dispute.

This guide walks you through every line of a pro forma invoice (PI), shows you exactly which numbers to verify, and gives you a checklist you can apply to every order from China, India, Turkey, or anywhere else you source. By the end, you'll know how to spot the five most common traps, when to push back, and what to confirm in writing before you send a deposit.

What a Pro Forma Invoice Actually Is (and Isn't)

A pro forma invoice is a good-faith quotation formatted like an invoice. It is issued before goods are produced, before payment is made, and often before final specifications are locked. It is not a receipt, not a contract, and not proof that your supplier has the goods in stock. However, once you pay a deposit against it, most Chinese suppliers treat the PI as the binding order confirmation. That means whatever is written on the PI — including typos, wrong HS codes, and vague spec descriptions — becomes the baseline for what you receive.

This is why I call it a 'sanity' pro forma invoice: it's your last chance to sanity-check the deal before money leaves your account. Every line should be read as if it will be enforced in a dispute, because in practice it usually is.

It is a quotation, not a tax invoice — you cannot use it for customs clearance or VAT recovery on its own.
It becomes binding once you pay a deposit and the supplier confirms receipt.
It is the master reference for your QC inspection, packing list, and commercial invoice later.
It is negotiable until you sign or pay — after that, changes cost time and money.
It is not a guarantee of quality; specs must be attached separately as a written specification sheet.

The 12 Fields You Must Verify Line by Line

A standard PI from a Chinese supplier has roughly 12 fields. Most buyers skim the total and wire the money. Don't. Each field is a potential dispute. Below is the exact order I check them in, and what 'correct' looks like.

1. Seller and Buyer Details

The seller's legal name must match the bank account name exactly. If the PI says 'Shenzhen Brightstar Lighting Co., Ltd' but the bank beneficiary is 'Bright Star Trading HK,' stop. That mismatch is the single biggest red flag for fraud and a common cause of frozen wires. The buyer name should match your company name as it appears on your import license or bank account.

2. PI Number and Date

Every PI should have a unique reference number (e.g. BST-2024-0417) and a date. You will quote this number in every email, payment reference, and inspection request for the next 90 days. If your supplier sends a PI without a number, ask them to reissue it — this is a sign of a disorganised operation.

3. Product Description and Specs

This is where 80% of disputes start. 'LED bulb 12W E27' is not enough. You need model number, wattage, colour temperature (e.g. 4000K), voltage (220V for most African markets), base type, lumen output, IP rating, and packaging type. Attach a signed spec sheet and reference it on the PI.

4. Quantity and Unit

Confirm the unit — pieces, sets, cartons, or pallets. A PI that says '5,000 pcs' when you negotiated '5,000 sets' is a 3x price difference. Also confirm the MOQ is met; if you ordered below MOQ, expect a surcharge clause.

5. Unit Price and Currency

Check the currency code (USD, EUR, CNY) and the Incoterm (FOB, EXW, CIF, DDP). A $2.40 FOB Shenzhen price is very different from a $2.40 EXW price — the EXW price excludes inland freight to port, which typically adds $150–$400 per shipment depending on volume.

6. Total Amount and Payment Terms

Standard terms for a first order are 30% deposit, 70% before shipment. For orders under $3,000, some suppliers ask for 100% upfront — negotiate down to 50/50 if possible. Never pay 100% upfront to a new supplier on Alibaba; use Trade Assurance if available.

7. Lead Time

Typical production lead time is 15–30 days for stock items and 30–45 days for custom or private-label goods. Add 7–14 days for sea freight booking and 25–40 days transit to Mombasa, Lagos, or Durban. If the PI says '7 days,' ask whether that's production or dispatch.

8. Bank Details

Verify the beneficiary name matches the seller name, the SWIFT code is correct, and the bank is in the same country as the seller (usually). Hong Kong bank accounts for a mainland Chinese factory are common and legitimate, but demand a written explanation and the company's business license.

9. HS Code and Country of Origin

The HS code determines your import duty. If the supplier writes 'LED lights' with no code, ask for the 6-digit HS code (e.g. 9405.42). Wrong codes cause customs delays and unexpected duty bills.

10. Additional Charges

Watch for line items like 'mold fee,' 'sample fee,' 'bank charge 3%,' 'documentation fee $50,' or 'pallet fee.' Some are legitimate (mold fees for custom plastic are real, often $500–$3,000), but they should be itemised and agreed in advance.

11. Validity Period

A PI should state how long the price is valid — typically 15–30 days. Raw material prices for metals and plastics move fast; a PI without a validity date lets the supplier re-quote after you've planned your budget.

12. Signature and Company Chop

A real PI has the supplier's company chop (red stamp) and a signatory name. No chop = not authoritative. Ask for a scanned copy with the chop, and keep it.

Match seller name to bank beneficiary name — no exceptions.
Confirm unit price, currency, and Incoterm (FOB vs EXW changes landed cost by 5–15%).
Verify product specs against your signed spec sheet, not the PI alone.
Check total, deposit %, and balance terms before paying.
Confirm lead time, HS code, and validity period in writing.

How to Sanity-Check the Numbers Before You Pay

Once the PI looks clean, run the numbers through a landed-cost calculator. This is where most African and emerging-market importers get surprised. A $2.40 FOB unit price does not mean $2.40 landed. Add freight, insurance, duty, clearing, and inland transport, and your real cost is often 35–60% higher.

Use a tool like Freightos or Flexport's instant quote to sanity-check the freight line. For a 20ft container from Shenzhen to Mombasa, expect $1,800–$3,200 depending on season. To Lagos (Apapa), $2,200–$3,800. To Durban, $1,500–$2,800. If your supplier quotes CIF at $800, they're either subsidising it (rare) or hiding charges elsewhere.

Freight: $1,800–$3,800 per 20ft depending on destination and season.
Marine insurance: 0.3–0.5% of CIF value (often $30–$80).
Import duty: 0–35% depending on HS code and country (check your customs tariff).
Clearing agent: $250–$600 per container in most African ports.
Inland transport: $300–$1,200 depending on distance from port.
Bank wire fees: $25–$60 per transfer via Wise or your bank; 1–3% if using a local bank with FX spread.

Worked Example: 5,000 LED Bulbs

PI says: 5,000 pcs at $2.40 FOB Shenzhen = $12,000. Freight (CIF Mombasa) = $2,400. Insurance = $60. CIF total = $14,460. Duty at 25% = $3,615. Clearing = $450. Inland to Nairobi = $400. Bank fees = $50. Total landed = $18,975, or $3.80 per unit. If you were planning to sell at $5, your margin just dropped from 52% to 24%. That's the sanity check.

Red Flags That Should Stop You Cold

Some PI problems are fixable with an email. Others mean walk away. Learn the difference. A missing spec detail is fixable. A bank account in a different country than the seller, with no explanation, is not.

Beneficiary name doesn't match seller name — 90% of wire fraud starts here.
Bank account in a third country (e.g. seller in China, bank in Cyprus) with no written explanation.
Prices 40%+ below market — usually means bait-and-switch or substandard materials.
No company chop, no PI number, no validity date — disorganised or fake supplier.
Payment requested via Western Union, MoneyGram, or personal PayPal — never do this for B2B goods.
Specs described in vague marketing language ('high quality,' 'premium') instead of measurable numbers.

If you see two or more of these, pause. Ask for the business license, verify the company on Alibaba's Trade Assurance or a third-party like QIMA or SGS, and consider a $200–$400 supplier verification before wiring anything.

Common Mistakes Buyers Make on Pro Forma Invoices

Mistake 1: Paying the deposit before reading the spec line. Buyers focus on price and miss that the PI says '9W' instead of '12W.' Fix: compare the PI spec line to your signed spec sheet word by word.

Mistake 2: Ignoring the Incoterm. A $2.40 EXW price looks cheaper than $2.60 FOB, but EXW excludes inland freight to port ($150–$400), so you pay more in the end. Fix: always convert to FOB or CIF before comparing quotes.

Mistake 3: Accepting 'bank charges 3%' as a line item. This is often a hidden margin. Fix: negotiate it to a flat $30–$50 or pay via Wise, which charges 0.4–1% for USD transfers to China.

Mistake 4: Not checking the HS code. A wrong HS code can double your duty or trigger a customs hold. Fix: verify the 6-digit code against your country's tariff schedule before paying.

Mistake 5: Wiring to a personal account or a name that doesn't match the PI. This is the #1 cause of lost deposits. Fix: only wire to the company name on the PI and the business license.

Mistake 6: Skipping the validity date. Raw material prices move; a PI without a validity period lets the supplier re-quote after you've budgeted. Fix: insist on 'Price valid for 30 days from PI date.'

Conclusion: Your 5-Minute Pre-Payment Checklist

A pro forma invoice is your last line of defence before money leaves your account. Read it like a contract, because it becomes one. The four things that matter most: (1) seller name must match bank beneficiary name exactly; (2) specs must be measurable and match your signed sheet; (3) Incoterm and total landed cost must be calculated, not assumed; (4) payment terms should never be 100% upfront for a new supplier.

Next step: download your supplier's PI, open it side by side with your spec sheet and a landed-cost calculator, and run the 12-field checklist above. If anything is missing or mismatched, send one consolidated email listing every correction before you wire a cent. Then, for orders above $5,000, book a third-party inspection with QIMA or SGS ($200–$400) before the balance payment. That single inspection has saved more importers from disaster than any negotiation tactic.
