Foundation · Course 8: Jobs and Departments · Lesson 2 of 5

The main departments inside a buying company or brand, and what each one does

Level: FoundationTime: 40 minutesOrder used: A (the T-shirt) — Northline Apparel's buyer-side departments, contrasted with Cedar & Co.'s combined-role domestic structureTool: Department directory
This lesson is for anyone who deals with a buying company or brand and needs to know which department to contact for a given question: a factory merchandiser, a new buying-office employee, or a student. Lesson 8.1 (departments inside a factory) is useful background but not required. Money and headcount figures are teaching examples. At work, use the real numbers of your own company.

02Opening

This page is for anyone who needs to know which department inside a buying company or brand actually handles a given question, and it teaches mainly the people who do that work

Lesson 8.1 looked inside a garment factory and named its departments. This lesson turns to the other side of the order: the buying company or brand itself. A buying company or brand splits its own work across departments too, and a factory contact who does not know which one owns which decision wastes time asking the wrong person, or worse, accepts an answer from someone with no authority to give it. At work, a merchandiser at a factory needs to know that a design question goes to one buyer-side department, a price or quantity question goes to another, and a compliance question goes to a third, even when the buying company is small. This lesson mainly teaches the people flow: who, inside a buying company, is responsible for what. By the end, you can name the main buyer-side departments and route any question to the right one, on an order of any size.

03Before you start

What you need, and what this lesson does not cover

You need: the idea of a buyer from Course 1, and the four company categories from lesson 2.1. Lesson 8.1's factory-side departments are useful background but not required.

By the end of this lesson you can:

  • name the three main buyer-side departments (design, buying office or merchandising, and quality or compliance) and say what each one owns;
  • state which department creates the tech pack a factory produces against;
  • state Northline Apparel's fixed buying-office headcount;
  • explain why a small domestic brand may combine these three functions into far fewer people without losing any of the functions themselves;
  • use the method to work out which buyer-side department a given question belongs to, on any order.

Not covered here: the day-to-day work of a merchandiser (lesson 8.3), the quality and compliance function in full (lesson 8.4), and career paths across these departments (lesson 8.5).

05Teaching
The rule

A buying company or brand splits its work across departments, and each department owns a different kind of decision

Just as a factory has separate departments for production, merchandising and quality (lesson 8.1), a buying company or brand splits its own work the same way. A design department decides what the product should look like or be made of. A buying office, sometimes called the merchandising team, places the order, agrees the quantity and price, and approves samples. A quality or compliance function sets the standard the factory must meet and checks the factory meets it. Knowing which department owns which kind of decision tells a factory who to actually ask, instead of guessing from whoever answers the phone.

Designwhat the productshould beBuying officequantity, price,sample approvalQuality orcompliancethe required standard
Three buyer-side departments own three different kinds of decision.* Design decides what is made; the buying office decides how much, at what price, and approves what the factory produced; quality or compliance sets and checks the required standard.
What you meet in real life

The same three functions exist at every buying company, but the number of people doing them changes a great deal

What can differThe shapes you will meetWhy it matters to you
Company sizeA large export brand may have separate design, buying and quality teams, each with several people. A small domestic brand may have one or two people covering all three functions.The functions do not disappear when the company is small; they are simply carried by fewer people, sometimes one person wearing more than one hat.
Export or domesticAn export brand like Northline Apparel sets a quality standard and sometimes visits the factory to audit it, because the goods cross a border and cannot easily be returned. A domestic brand like Cedar & Co. often checks quality more informally, since it can visit or return goods more easily.Knowing whether an order is export or domestic tells you how formal the buyer-side quality function is likely to be.
Make to order or make to stockA make-to-order buyer such as Northline Apparel places one confirmed order at a time, with its buying office approving samples order by order. A make-to-stock buyer such as Cedar & Co. plans from its own forecast, so its buying decisions happen on a schedule set by the brand, not by a single confirmed purchase order.The business model changes when buying decisions are made, but not which department makes them.
Who visits the factorySome buyers send their own quality staff to audit a factory in person. Others rely on a third-party inspection company (a service or compliance company, lesson 2.1) instead of, or alongside, their own staff.A factory contact must know whether a compliance visit is the buyer's own staff or an outside inspector, since the two carry different authority.

None of these shapes is more correct than another; a lesson later in this course, merchandising, follows one of these departments in full detail. What decides which department owns a given question is the kind of decision it is, using the method below, not the size of the company asking it.

The case we follow

Order A: Northline Apparel's three buyer-side departments, and Cedar & Co.'s combined domestic structure

Northline Apparel's design team created the tech pack that Delta Garments produces Order A against: the specification for the basic cotton T-shirt, its measurements, fabric and construction. Northline Apparel's buying office, a fixed team of 6 people including Sara, places the order for 15,000 pieces, agrees the FOB price, and approves the samples Delta Garments submits before bulk production starts. Northline Apparel's own quality or compliance function sets the AQL standard that Delta Garments' quality assurance department (lesson 8.1) inspects the finished T-shirts against.

Cedar & Co., a small domestic brand with 12 shops, buys from Delta Garments too, but on a much smaller scale and on open account rather than a letter of credit. Cedar & Co. does not need to be a specific known size for this comparison to hold: what the case shows is that a domestic brand of Cedar & Co.'s scale is unlikely to run three separate large departments the way Northline Apparel does. Its design, buying and quality functions more likely sit with the same small team, or even with Omar, its owner, directly.

DepartmentNorthline Apparel (Order A)Cedar & Co. (domestic)

The worked number

Northline Apparel's 6-person buying office against Delta Garments' 600 sewing operators

Northline Apparel's buying office headcount is fixed at 6 people. Delta Garments' sewing floor has 600 sewing operators (lesson 8.1). Comparing the two shows how small a buying-side team can be relative to the factory-side staff working on the same order, without that gap being a sign the buying office is under-resourced.

Delta Garments' sewing operators per person in Northline Apparel's buying office: 6 × 100 = 600
Headcount on each side of Order A Buying office 6 Delta Garments' sewing operators 600
A 6-person buying office routinely manages an order worked on by 600 factory-side staff.* The ratio is a normal feature of the industry, not evidence that the buying side is too small to run its functions properly.
The method

Three questions that route any buyer-side question to the right department

  1. Ask what the question is actually about. Is it about what the product should look like or be made of, or is it about something else?
  2. If it is about price, quantity, or approving something the factory already did, ask the buying office. That includes agreeing the FOB price, confirming the order quantity, and approving a submitted sample.
  3. If it is about whether the factory meets a required standard, ask quality or compliance. That includes the AQL level, a compliance certificate, or scheduling an audit visit.
  4. If the buying company is small, ask which person covers that function today, rather than assuming a named department exists, since one person may cover more than one function.
The trap

Assuming a domestic brand like Cedar & Co. must have the same separate departments as Northline Apparel, just smaller

A common mistake is to assume that every buying company, however small, must run the same three separate departments as a large export brand, only with fewer people in each. A small domestic brand often combines design, buying and quality into far fewer people, or even one person such as Omar wearing multiple hats. The functions this lesson describes still exist and still need doing; the department boundaries a larger brand uses do not automatically transfer to a smaller one. Assuming otherwise leads a factory contact to expect, and wait for, a department that was never going to exist in that shape.

06In plain words

A buying company splits its work into three kinds of job. One team decides what the product should be, using a document called a tech pack. One team, the buying office, agrees the quantity and price and approves what the factory made. One team sets and checks the quality standard. A large export company may run these as three separate departments with several people each. A small domestic company often runs all three with a much smaller team, sometimes one person. The jobs do not disappear when the company is small; they are simply carried by fewer people. To find the right department, ask what kind of question it is, not how big the company is.

07Quick check
  • Design decides what the product should look like or be made of, using the tech pack.
  • The buying office decides quantity and price, and approves samples the factory submits.
  • Quality or compliance sets the required standard and checks the factory meets it.
  • A small buying-office headcount does not mean the buying side is under-resourced; a few people can manage an order involving hundreds of factory staff.
  • A small domestic brand can combine all three functions into far fewer people, or even one person, without losing any of the functions.
  • Ask which function a question belongs to, not which named department exists, especially at a smaller buying company.
08Workplace scenario

A new factory contact tries to reach Northline Apparel's quality department about a compliance audit date and is told the buying office handles it too

A new employee at Delta Garments tries to reach Northline Apparel's "quality department" to confirm the date of a compliance audit. Northline Apparel's reply says the buying office handles that question too, since the company is small on the buyer side relative to the factory.

Email reply from Northline Apparel's buying office. "We do not have a separate quality department large enough to answer this alone; our buying office, including the person who set the AQL standard for this order, handles quality and compliance questions as well. Please send the audit request here."

Does a buyer having only 6 people mean it cannot properly run separate department functions? Decide before opening the answer.

Show decision

Not necessarily. A small headcount can still run distinct functions, design, buying, and quality or compliance, even if the same few people wear more than one hat, rather than each function needing its own large separate team.

First, the functions are about work, not headcount. The buying office's reply shows that the person who set the AQL standard is still inside the same small team; the quality function was done, just not by a separately named department.

Second, the size of the buying side is not evidence of a problem on its own. Northline Apparel's buying office of 6 people already manages an order involving 600 factory-side sewing operators (the worked number above), a normal ratio in the industry. A small headcount routinely covers more than one function without any function going undone.

The functions this lesson describes are about what work needs doing, not a fixed rule about company size or team structure. Delta Garments' new contact should confirm which person currently covers compliance, not assume a missing department means the function is missing too.

09What it costs

What misdirecting a compliance question to the wrong buyer-side contact costs

This lesson is framed qualitatively, because the cost depends on the order, not on a fixed figure. Misdirecting a compliance question to the wrong buyer-side contact, for example assuming a large dedicated quality department exists at Northline Apparel when it does not, wastes time on both sides while the message is forwarded to whoever actually covers that function that week. At a smaller buying company such as Cedar & Co., where design, buying and quality may sit with one or two people or even with Omar directly, the same mistake can delay an audit date or a sample approval by days, since there may be no separate department to redirect the message to at all. The cost is avoided simply by asking which function, not which named department, handles a given question, especially at a smaller buying company.

10Working template

Department directory: adding the buyer-side departments for Order A

Course 8's workbook lists departments on both sides of an order. Fill in the buyer-side rows: department, company side, Northline Apparel's fixed headcount of 6, and key responsibility.

DepartmentCompany sideHeadcount (if known)Key responsibility
DesignBuyerCreates the tech pack and specification the factory produces against
Buying officeBuyer6Places orders, approves samples and prices, the main contact for the factory
Quality or complianceBuyerSets the AQL standard, sometimes audits the factory

Add a note in the "Works with" column for Cedar & Co.'s row: its smaller domestic team likely combines these three roles across fewer people, without giving Cedar & Co. a specific headcount.
