FedEx Pro Forma vs Commercial Invoice: Which to Use?
Use the commercial invoice unless the shipment is genuinely not a sale and the destination accepts a pro forma. Free samples, warranty parts, and goods going out for repair are the usual exceptions, and sending the wrong document is what gets a shipment held and charged storage.
| Factor | Pro Forma Invoice | Commercial Invoice |
|---|---|---|
| Timing | Before order, or at shipping | When goods are ready |
| Purpose | A quote, or free shipment | Final, official bill of sale |
| Customs role | Non-sale shipments only | Main document for clearance |
| Legal weight | Preliminary offer | Record of the sale |
A pro forma does two different jobs: one at quoting time, and one as the customs document for shipments with no sale behind them.

Which One FedEx Wants
FedEx starts from the same rule, and the destination decides whether the exception applies. Its shipping tool offers both documents because its customers ship both kinds.
| Your shipment | Invoice FedEx expects |
|---|---|
| Any sale, paid or unpaid | Commercial |
| Free sample, no charge | Pro forma |
| Warranty or replacement part | Pro forma |
| Goods out for repair | Pro forma |
| Exhibition goods coming back | Pro forma |
Seeing two options in FedEx Ship Manager is not a sign that one of them is wrong. You can create or upload either document, so the choice is yours to make correctly rather than a setting to guess at.
Some destinations want a commercial invoice either way. FedEx’s own US guidance treats a commercial invoice as the baseline for goods crossing a border, so confirm the requirement for your destination before you rely on a pro forma. A free sample sent on the wrong document becomes a held parcel.
Why the Pro Forma Invoice Matters to You
The pro forma invoice is your last easy chance to fix the deal before any money moves. It is the supplier’s written offer: what you are buying, the price, the quantity, and the terms. Read it like a quote you are about to commit to, because once you pay, that is exactly what it becomes.
This is where you catch the cheap mistakes. Confirm the price, check the quantity, and pin the delivery and payment arrangements down on paper before production starts. Fixing something here costs an email, and fixing it after you have paid costs real money.
Checking each invoice before money moves is the first thing purchase management does on any order.
Why the Commercial Invoice Can Hold Your Goods
The commercial invoice is the document that can stop your shipment cold. It is the official bill of sale, issued when the goods are ready to ship.
Every number on it has to match what is really in the container. If the description, quantity, product code, or value does not match, customs can flag the shipment, hold it, and charge you storage for every day it sits. Your declaration, your customs value, and your duty are all built on this one document, which is why customs clearance from China turns on getting it right.
It is also what you check before paying the balance. The invoice states the full value of the goods. Your deposit and balance are a separate payment plan, and the two should never get mixed up on the document itself.
A pro forma that no longer matches the final invoice is a warning sign, not a customs offense. Terms change and documents get reissued. What customs compares is the commercial invoice, the transport document, and the goods themselves, so the figures that have to be right are the ones on the final declaration.
Where Each Invoice Fits in Your Order
A typical import from China runs through five stages, and each invoice has its place. Knowing the order tells you exactly when to slow down and check.
Step 1: Supplier sends its pro forma. After you agree on specifications, the supplier confirms the product, unit price, quantity, and the shipping and payment terms in writing. Buyers weighing FOB vs EXW, or deciding whether CIF shipping terms fit the shipment, lock those choices in here.
Step 2: You issue a purchase order and pay the deposit. Send an order document that mirrors the supplier’s offer and pay the agreed deposit. Production begins.
Step 3: Goods are inspected before the balance. A pre-shipment inspection confirms the goods match the specification before you pay the rest.
Step 4: Supplier issues the commercial invoice. Once production is done, the supplier issues it showing the full price of the goods, not the balance you still owe. It travels alongside a packing list and the transport document, an air waybill on a FedEx parcel or a bill of lading on a sea shipment, as part of your shipping documents.
Step 5: You verify and pay the balance. Set the final invoice beside your purchase order and the inspection results. If everything matches, the balance is released and shipment is arranged.
What to Check on Each Invoice
You do not need to memorize every field, only the few that cause problems. On the commercial invoice, make sure the product description and its classification code match the actual goods, since that code sets your duty rate. Confirm the quantity, values, and total are right and that it references your purchase order.
Never let a supplier talk you into a lower declared figure to save duty. The declared value drives the US tariffs you pay, and understating it is customs fraud, with the fines, seizure, and audits landing on you rather than them.
On that offer document, the one field buyers forget is the validity date. Without it the price can quietly change before you accept. If you are still at the request for quotation stage, your quotation says what you want and the pro forma coming back is its formal yes.
What a Code Mismatch Costs
This is a constructed example, but the pattern behind it is common. A buyer ships electronic accessories from Shenzhen by FedEx. The pro forma listed one product code, and the commercial invoice uploaded at booking used a different, broader electronics code that did not match how the goods were described.
The mismatch surfaces at import. Customs queries the description against the code, the parcel is held, and it stays held until a corrected invoice is submitted.
The duty is rarely the expensive part. Storage, a re-declaration, and a missed delivery date add up on an error that took minutes to make. The fix is checking the classification on the final invoice before the courier collects.

FAQ
Q1: Does accepting a pro forma invoice commit me to buy?
On its own it is usually a formal offer rather than a binding contract, so accepting it does not always lock you in. Your commitment normally firms up once an order document goes out or a deposit is paid, though some suppliers word a pro forma to imply otherwise.
Q2: Is a supplier’s pro forma the same as a purchase order?
No. The pro forma comes from the supplier and states their offer. The purchase order comes from you and confirms you accept it, which gives you a record in your own words rather than only theirs.
Q3: Can I change the quantity or price after the pro forma is issued?
Yes, and changes are normal, but they have to flow through to the final documents. Have the supplier reissue the pro forma, then make sure the commercial invoice and purchase order show the new figures.
Q4: Does the commercial invoice have to match the packing list and transport document?
Yes, and this trips up many buyers. Descriptions, quantities, and weights should agree across all three, because that set travels with the goods and one figure out of step can trigger an inspection.
Q5: FedEx Ship Manager wants an invoice uploaded. Which file do I attach?
The commercial invoice for a sale, and a pro forma for anything sent free of charge. Upload it before the parcel leaves the factory, since a document added later often arrives after the goods do.
Q6: Can I send a free sample through FedEx on that document?
Where the destination accepts one, yes, provided you declare what the goods are really worth. Marking the shipment as not for sale is fine; putting zero or a token figure in the value box is what gets the parcel stopped.
Q7: If the code on the invoice is wrong, who is liable at customs?
As the importer, you usually carry it even when the supplier prepared the code. That is why checking the classification before shipment protects you, not the party that typed it.
Q8: What do I do if the goods already shipped with a wrong invoice?
Ask the supplier for a corrected commercial invoice straight away, since customs will often clear the shipment once the amended document is submitted. Bring your forwarder or broker in early, because storage charges keep building while the cargo waits.
Conclusion
A pro forma is not a cheaper version of a commercial invoice. On a purchase it sets up the deal you have yet to pay for, and on a free shipment it becomes the customs document in its own right. Swapping one for the other on a real sale is the expensive version of this mistake.
The practical rule is simple: hold the final invoice up against the offer you accepted and your purchase order before the last payment leaves. We build that check into purchase management so it happens on every order rather than on the ones you remember.
