Import from China 101 – Chapter 8: Signing the Proforma Invoice or Sales Contract and Starting Production

8.1 Sending a Purchase Order (PO) to the Supplier and Requesting a Proforma Invoice (PI)

When starting mass production, two key documents help formalize the transaction:

Purchase Order (PO): Issued by the buyer to confirm the order details.
Proforma Invoice (PI): Issued by the supplier to confirm pricing and payment terms.

Understanding PO and PI processes ensures clear agreements, prevents misunderstandings, and protects both parties in international trade.


8.1.1 What is a Purchase Order (PO)?

A Purchase Order (PO) is a formal document sent by the buyer to the supplier, stating the products they wish to purchase along with all agreed terms.

A PO typically includes:

Product details: Name, specifications, quantity.
Pricing: Unit price, total amount, additional costs (e.g., shipping fees).
Delivery terms:Expected shipping date, destination, and delivery terms (FOB, CIF, DDP, etc.).
Payment terms: Payment method (T/T, PayPal, L/C), deposit, and final balance payment conditions.
Other conditions: Quality requirements, inspection terms, warranty details.

Why is a PO important?
– Acts as a formal confirmation of the order.
– Helps prevent disputes by setting clear expectations.
– Can be used as a legal document in case of disagreements.


8.1.2 What is a Proforma Invoice (PI)?

A Proforma Invoice (PI) is a preliminary invoice issued by the supplier before production begins.

A PI typically includes:

Supplier details โ€“ Name, address, contact information.
Product information โ€“ Name, quantity, unit price, total price.
Payment terms โ€“ Deposit percentage, final payment conditions, bank details.
Shipping terms โ€“ Delivery method (Sea, Air, Express), estimated shipping time.
Additional terms โ€“ Customs clearance responsibilities, warranties, insurance.

Why is a PI important?
– Acts as a final price confirmation before payment.
– Serves as a basis for deposit payment to start production.
– Ensures the supplier understands the exact requirements before manufacturing.


 8.1.3 PO & PI Workflow

Here’s how the process typically works:

Step 1: The Buyer Sends a PO
The buyer submits a Purchase Order (PO) with product details, price, quantity, and payment terms.

Step 2: The Supplier Issues a PI
The supplier sends a Proforma Invoice (PI), confirming the order details and requesting a deposit.

Step 3: The Buyer Pays the Deposit
After reviewing the PI, the buyer pays the deposit (typically 30%-50%) to initiate production.

Step 4: The Supplier Begins Production
Once the deposit is received, the supplier starts production and provides an estimated completion date.

Step 5: The Buyer Pays the Final Balance
Before shipment, the buyer pays the remaining balance, and the supplier prepares the goods for delivery.


8.1.4 Why Are PO and PI Important?

Prevents misunderstandings: Ensures both parties agree on pricing, quantity, and payment terms.
Provides legal protection: If a dispute arises, PO/PI can be used as evidence.
Secures payments: Prevents fraud and ensures deposits go toward confirmed orders.

TIP: Always compare the PO and PI to ensure they match exactly before making any payments!


8.1.5 Best Practices for Managing PO & PI

Double-check PO details: Ensure product specs, price, and quantity are accurate before sending.
Carefully review PI: Make sure it matches the PO before paying the deposit.
Clarify payment terms: Avoid confusion about payment schedules, methods, and deposit amounts.
Track all communications: Keep records of emails, invoices, and payment confirmations for legal protection.


Summary: Securing a Smooth Production Start

Send a PO to the supplier with clear order details.
Receive a PI to confirm pricing and payment terms.
Pay the deposit only after verifying the PI details.
Monitor production and ensure the supplier meets deadlines.
