In apparel manufacturing, agreeing on a garment style, price, and quantity is not enough.

The buyer and supplier need a formal document that clearly records the commercial details of the order.

That document is called a Purchase Order, commonly known as a PO.

A garment purchase order usually confirms important information such as:

• Style number

• Product description

• Colour

• Size range

• Quantity

• Unit price

• Delivery date

• Shipping terms

• Payment terms

For apparel buyers, clothing brands, merchandisers, and manufacturers, the PO is one of the most important documents in the entire garment order process.

This guide explains what a garment PO is, what information it should contain, how it is used, and what buyers should check before confirming production.

What Is a Garment Purchase Order?

A Garment Purchase Order (PO) is an official commercial document issued by a buyer to a garment manufacturer or supplier.

It confirms the details of the order the buyer wants the supplier to produce.

The PO may include:

• Buyer name

• Supplier name

• PO number

• PO date

• Style number

• Product description

• Colour

• Size

• Quantity

• Unit price

• Total value

• Delivery date

• Payment terms

• Shipping instructions

Once accepted by the supplier, the PO becomes a key reference for production, merchandising, packing, invoicing, and shipment.

Why Is a Purchase Order Important?

A garment PO helps both buyer and supplier work from the same commercial information.

Without a clear PO, misunderstandings may occur regarding:

• Quantity

• Price

• Size ratio

• Colour ratio

• Delivery date

• Shipment destination

A properly prepared PO reduces confusion and creates a documented record of the order.

Purchase Order vs Tech Pack

A PO and a tech pack serve different purposes.

Purchase Order

Focuses mainly on commercial information.

It may include:

• Quantity

• Price

• Delivery

• Style

• Colour

• Size

Tech Pack

Focuses mainly on technical product details.

It may include:

• Measurements

• Fabric

• Construction

• Artwork

• Trims

• Labels

• Packaging

The PO tells the factory what is being ordered commercially.

The tech pack tells the factory how the garment should be made technically.

Both documents are important.

Purchase Order vs Order Sheet

Some companies use terms such as:

• Order sheet

• Sales order

• Buyer order confirmation

These may contain similar information.

However, a PO is generally the buyer's formal purchasing document.

The exact format varies between companies.

Who Issues the Garment PO?

The PO is usually issued by:

• Clothing brand

• Retailer

• Wholesaler

• Importer

• Buying house

• Export buyer

The supplier or manufacturer then reviews and confirms the details.

When Is a PO Issued?

A PO is usually issued after key commercial terms are agreed.

The typical sequence may be:

Product Enquiry → Costing → Negotiation → Sample Approval → Price Confirmation → PO Issued → Production Planning

In some businesses, the PO may be issued earlier, with final technical approvals completed afterward.

Key Details in a Garment Purchase Order

A professional garment PO should clearly include the main commercial information.

Let us look at each section.

1. Purchase Order Number

Every PO should have a unique identification number.

Example:

PO No: PO-2026-0185

This helps the buyer and supplier track the order.

The PO number may appear on:

• Production records

• Packing list

• Invoice

• Shipment documents

2. PO Date

The PO date records when the order was officially issued.

Example:

PO Date: 09 October 2026

This can be useful for:

• Order tracking

• Documentation

• Payment terms

• Lead-time calculations

3. Buyer Details

The PO should clearly show the buyer's information.

This may include:

• Company name

• Address

• GST details

• Contact person

• Phone

• Email

The exact information depends on the transaction.

4. Supplier Details

The manufacturer's details should also be included.

This can include:

• Supplier name

• Factory address

• Tax details

• Contact information

This confirms who is responsible for supplying the order.

5. Style Number

The style number is a unique code assigned to a garment design.

Example:

Style No: TS-104

The style number helps distinguish one product from another.

It may appear in:

• Tech pack

• Samples

• BOM

• Production reports

• Packing list

6. Product Description

The PO should describe the garment clearly.

Example:

Men's Regular Fit Polyester Sports T-Shirt

A vague description such as:

T-Shirt

may not be sufficient if the buyer has many styles.

7. Colour

Each garment colour should be clearly listed.

For example:

• Black

• Navy

• White

• Olive

If the order has several colours, each colour should ideally have its own quantity breakdown.

8. Size Range

The PO should show the required size range.

For example:

• S

• M

• L

• XL

• XXL

The buyer should ensure these sizes match:

• Approved size chart

• Tech pack

• Size-set sample

9. Size Ratio

A PO may specify how many pieces are required in each size.

Example:

Size	Quantity
S	100
M	250
L	300
XL	220
XXL	130

Total:

1,000 pieces

This is called the size ratio or size breakdown.

10. Colour-Wise Quantity

If the same style is produced in multiple colours, quantity should be divided clearly.

Example:

Colour	Quantity
Black	500
Navy	300
Olive	200

Total:

1,000 pieces

11. Colour and Size Matrix

Many POs use a matrix to show both colour and size breakdown.

Example:

Colour	S	M	L	XL	XXL	Total
Black	50	120	150	110	70	500
Navy	30	75	90	65	40	300
Olive	20	55	60	45	20	200
Total	100	250	300	220	130	1,000

This makes production planning easier.

12. Order Quantity

The total order quantity should be clearly stated.

Example:

Total Order Quantity: 1,000 Pieces

The supplier should compare this with:

• Colour breakdown

• Size breakdown

The totals must match.

13. Unit Price

The PO should show the agreed price per garment.

Example:

Unit Price: ₹350 per piece

or for export orders:

USD 4.20 per piece

The currency must be clearly stated.

14. Total Order Value

The total order value is calculated using:

Unit Price × Order Quantity

Example:

1,000 pieces × ₹350

= ₹3,50,000

The PO should make this clear.

15. Currency

Currency should never be assumed.

Common examples include:

• INR

• USD

• EUR

• GBP

The same number can represent very different values depending on the currency.

16. Delivery Date

The PO should clearly state the required delivery date.

Example:

Delivery Date: 20 November 2026

This date may refer to:

• Ex-factory date

• Dispatch date

• Shipment date

• Delivery-to-warehouse date

The buyer and supplier should agree on what the date means.

Why Delivery Date Must Be Clear

A buyer may say:

“Delivery required by 20 November.”

But the supplier may interpret this as:

Factory dispatch date

while the buyer expects:

Goods to reach warehouse

These are different.

The PO should define the required milestone clearly.

17. Shipping Destination

The PO may include the destination address.

This could be:

• Buyer's warehouse

• Retail distribution centre

• Port

• Freight forwarder

• Export destination

Correct destination details are essential for logistics planning.

18. Shipping Method

The shipment method may be mentioned.

Examples:

• Road

• Air

• Sea

• Courier

This is especially important for export orders.

19. Incoterms

International apparel orders may use Incoterms.

Examples include:

• EXW

• FOB

• CIF

• DDP

These terms define responsibilities for:

• Freight

• Insurance

• Customs

• Delivery

Buyers should understand the agreed Incoterm before confirming price.

20. Payment Terms

Payment terms explain when the supplier will be paid.

Examples:

• 50% advance, 50% before dispatch

• 30% advance, 70% after inspection

• Net 30 days

• Letter of Credit

Payment terms vary widely.

They should be agreed before production begins.

21. GST or Tax Details

Domestic Indian orders may specify whether:

• GST is included

• GST is extra

This should be clear in the PO.

For example:

Unit Price: ₹350 + applicable GST

This reduces invoice disputes later.

22. Packaging Requirements

The PO may include basic packing instructions.

Examples:

• One piece per polybag

• Size sticker required

• 20 pieces per carton

• Barcode required

Detailed packaging instructions may also be provided in a separate packing manual.

23. Label Requirements

The PO may reference:

• Brand label

• Size label

• Care label

• Hang tag

Technical details are usually included in the tech pack or BOM.

24. Special Instructions

A PO may also contain special notes.

Examples:

• No partial shipment

• Prior approval required for quantity variation

• Barcode must match SKU

• Buyer approval needed before dispatch

These instructions should be read carefully.

Example of a Simple Garment PO

A simplified PO may look like:

Buyer: ABC Clothing Pvt Ltd
Supplier: XYZ Garments
PO No: PO-2026-145
Style: TS-104
Product: Polyester Sports T-Shirt
Colour: Black, Navy
Sizes: S–XXL
Quantity: 2,000 pcs
Unit Price: ₹280
Total Value: ₹5,60,000
Delivery Date: 30 November 2026
Payment: 30% Advance / 70% Before Dispatch

This is a basic example.

Actual commercial orders may contain much more information.

PO and Garment Merchandising

The garment merchandiser uses the PO as a key order reference.

The merchandiser may verify:

• Style

• Colour

• Quantity

• Price

• Delivery date

before creating the production plan.

PO and Time & Action Calendar

Once the PO is confirmed, the merchandiser may create a T&A calendar.

The shipment date in the PO becomes the main deadline.

From there, the merchandiser plans backward:

• Final inspection

• Packing

• Finishing

• Sewing

• Cutting

• Fabric receipt

• Sample approval

This helps keep production on schedule.

PO and Production Planning

The production planning team uses the PO to understand:

• Style quantity

• Colour quantity

• Size ratio

• Delivery deadline

This helps decide:

• Which sewing line to use

• How many days are required

• When cutting should begin

PO and Material Planning

The PO quantity affects material requirements.

For example:

If the buyer orders:

5,000 T-shirts

the factory must calculate enough:

• Fabric

• Rib

• Thread

• Labels

• Packaging

based on the confirmed quantity.

PO and Fabric Consumption

Suppose one garment consumes:

0.30 kg fabric

Order quantity:

5,000 pieces

Basic fabric requirement:

5,000 × 0.30

= 1,500 kg

Then the factory may add the required allowance for:

• Cutting waste

• Fabric defects

• Shrinkage

The PO quantity therefore drives material planning.

PO and Garment Costing

The PO confirms the commercial price.

The factory must ensure the accepted price is sufficient to cover:

• Fabric

• Trims

• Labour

• Printing

• Packaging

• Overheads

A pricing error can affect supplier profitability.

PO and Invoice

The supplier invoice should usually match the agreed PO.

Important information includes:

• PO number

• Quantity

• Unit price

• Total amount

If invoice details do not match the PO, payment may be delayed.

PO and Packing List

The packing list may also reference the PO number.

This helps buyers identify which order is being shipped.

The packing list may show:

• Carton number

• Colour

• Size

• Quantity

PO and Shipment

Before dispatch, the supplier should verify that the shipment matches the PO.

Check:

• Correct style

• Correct quantities

• Correct colours

• Correct sizes

• Correct packaging

• Correct destination

A final PO review can prevent shipment mistakes.

Purchase Order Quantity Tolerance

Some buyers allow limited quantity variation.

For example:

Order quantity:

10,000 pieces

Allowed tolerance:

±2%

The factory may be allowed to ship slightly more or less than the exact quantity.

This must be agreed in advance.

Never assume overproduction will automatically be accepted.

Why Overproduction Happens

Factories may produce extra pieces to cover:

• Defects

• Quality rejection

• Cutting variation

However, extra production should be controlled.

The buyer may not pay for unauthorized quantities.

PO Amendment

Sometimes a buyer needs to change a confirmed PO.

Possible changes include:

• Quantity

• Colour

• Price

• Delivery date

• Destination

This should be done through a formal PO amendment or revised PO.

Important commercial changes should not rely only on verbal communication.

PO Revision Control

If a PO changes, the document should clearly show:

• Revision number

• Revision date

• Updated information

Example:

PO Revision: V2

This helps prevent the factory from using an outdated order.

What Buyers Should Check Before Issuing a PO

Before sending the PO, verify:

• Supplier name

• Style number

• Product description

• Colour

• Size range

• Quantity

• Price

• Currency

• Delivery date

• Payment terms

• Shipping address

A mistake in the PO can create problems across the entire production process.

What Suppliers Should Check After Receiving a PO

Manufacturers should not immediately start production without reviewing the PO.

Check:

• Price matches quotation

• Quantity matches negotiation

• Delivery date is achievable

• Colours are correct

• Size ratio is correct

• Payment terms are acceptable

Any difference should be clarified immediately.

Importance of PO Acknowledgement

Some suppliers formally acknowledge the PO.

This confirms that they:

• Received the order

• Reviewed the details

• Accept the terms

This reduces uncertainty.

Common Garment PO Mistakes

1. Wrong Style Number

This can result in the wrong product being produced.

2. Incorrect Quantity Total

Colour and size totals must match the main quantity.

3. Wrong Price

Always compare the PO against the final quotation.

4. Unclear Delivery Date

Specify whether it means dispatch or arrival.

5. Missing Currency

Never assume INR or USD.

6. Wrong Shipping Address

Can create expensive logistics problems.

7. Verbal Changes After PO

Important changes should be formally documented.

PO vs Proforma Invoice

A Purchase Order comes from the buyer.

A Proforma Invoice is usually issued by the supplier.

The supplier may use the PO information to prepare the proforma invoice.

A proforma invoice may confirm:

• Price

• Quantity

• Payment

• Product

before the final commercial invoice is issued.

PO vs Commercial Invoice

The PO is issued before or during order confirmation.

The commercial invoice is generally issued by the supplier for billing and shipment.

So:

PO = Buyer places order

Invoice = Supplier requests payment

PO vs Contract

A PO can form part of a commercial agreement.

However, larger apparel orders may also use:

• Supply agreement

• Manufacturing contract

• Terms and conditions

These documents may contain broader legal terms than the PO.

Garment PO Checklist

Before confirming a PO, check:

• PO number

• Date

• Buyer

• Supplier

• Style

• Description

• Colour

• Size

• Quantity

• Price

• Currency

• Delivery date

• Payment terms

• Packaging

• Shipping address

• Special instructions

Every key detail should be clear.

How Small Clothing Brands Can Use POs

Even small brands should use purchase orders.

A startup ordering:

100 hoodies

may think WhatsApp messages are enough.

This is risky.

A simple PO creates a clear record of:

• What was ordered

• At what price

• How many pieces

• When delivery is expected

It does not need to be complicated.

Simple PO Format for a Small Clothing Brand

A basic spreadsheet or PDF can include:

PO Number

Supplier

Style

Colour

Size

Quantity

Unit Price

Total

Delivery Date

Payment Terms

This is much safer than relying on scattered messages.

Why PO Discipline Matters as a Brand Grows

When a brand has:

• Multiple styles

• Several suppliers

• Different delivery dates

informal order management becomes difficult.

POs create structured order tracking.

For example:

PO-101 = T-Shirts

PO-102 = Hoodies

PO-103 = Track Pants

This makes supplier management easier.

Purchase Orders and Inventory

PO data can also help the brand plan inventory.

The buyer knows:

• What stock is coming

• How many pieces

• Which sizes

• Which colours

• Expected delivery date

This improves product-launch planning.

Purchase Orders and Cash Flow

A PO also represents a financial commitment.

For example:

PO value:

₹5 lakh

Payment terms:

50% advance

The buyer may need:

₹2.5 lakh upfront

Therefore, purchase orders should be connected to cash-flow planning.
