What a Supplier Brief Is and Why It Matters
A supplier brief is a short document, usually one to three pages, that tells a potential manufacturer what you want to make. It covers the brand, the products, the quantities, the quality level, the timing and the information you expect in the reply. It is sent at the start of the relationship, before a quotation, and it lets the factory judge whether the project is a fit and what to price. A good supplier brief saves time on both sides, because it filters out mismatches early and prompts the right questions.
Without a brief, factories guess. One quotes for a heavy fabric and another for a light one, one assumes printing and another does not, and the quotes cannot be compared. The reply you receive is only as good as the supplier brief you sent. Clear information also signals that you are a serious buyer, which tends to bring better attention from factories. A message that says only that you want hoodies cannot be quoted until many questions are answered.
If you are still choosing who to approach, read our guide on how to choose a clothing manufacturer. For the detailed specification that follows the brief, see the tech pack guide.
Supplier Brief vs Tech Pack vs Purchase Order
The three documents belong to different stages. The supplier brief is the early, short explanation of the project. The tech pack is the detailed technical specification with drawings, measurements, materials and construction. The purchase order is the formal instruction to produce, sent once the sample and the quote are approved. Many brands try to use the tech pack as a brief, but a factory looking at a long technical file cannot tell quickly whether the project suits it. Likewise, a brief is not detailed enough to produce from.
Send the supplier brief first. If the factory is interested, follow with the tech pack or a reference garment, then move to samples and, when ready, a purchase order. Our guide on how to make a clothing tech pack covers the detailed stage, and the clothing purchase order guide covers the last. Keep the three consistent, so nothing contradicts anything else.
Supplier brief vs tech pack vs purchase order
| Document | Stage | Length and detail | Purpose |
|---|---|---|---|
| Supplier brief | Before the quote | One to three pages, summary level | Explain the project and get a comparable quote |
| Tech pack | Sampling and development | Detailed drawings, measurements and materials | Specify exactly what to make |
| Purchase order | After approval | Quantities, prices and terms per style | Instruct production and delivery |
A general guide. Some brands combine or adapt these documents.
The Supplier Brief Template: Section by Section
The template below follows the order in which a factory reads. Start with who you are and what you want, then give the product detail, then the commercial and delivery points, then say what you need back. Each section can be a short paragraph or a few lines. If you do not know an answer yet, say so and give a range rather than leaving it blank, because a range is more useful than silence.
Supplier brief template
- About the brand: name, website, market and customer in two or three lines
- Product: garment type, style name and a reference image or sample
- Fabric: type, weight, composition and any finish or wash
- Fit and sizes: size range and fit, with a size chart if you have one
- Decoration: print, embroidery or labels, with placements
- Quantity: the order size per style, with colours and a range if unsure
- Quality: tests, certificates or inspection standard you expect
- Timing: when you need samples and delivery
- Delivery: destination and the Incoterm you prefer
- Reply format: price per style, minimums, lead times and payment terms
A general list. Add anything specific to your product or market.
Write the brief in plain language and avoid jargon the factory may not share. If a term could mean two things, such as a heavy fabric or a washed finish, add a short explanation or a reference. Put the most important facts, which are the product, the quantity and the timing, near the top, and keep optional details lower down. A factory that receives a supplier brief in this order can decide in a minute whether to reply and what to ask.
Send a reference garment or a clear image alongside the brief whenever possible, because pictures remove many questions at once. Name the file with the brand and style, and keep the supplier brief itself as a PDF or a short email that is easy to read on a phone.
Quantities, Price Targets and Commercial Terms
Factories price by quantity, so give a realistic number. If you are testing a style, say so and give the quantity you expect for the first order and a possible follow-up order. Our guide to MOQ in clothing manufacturing explains why minimums exist and how they vary. State how many colours and sizes you expect, because each adds set-up and fabric commitments.
Many buyers wonder whether to share a target price. A target price can help a factory propose the right fabric and construction, but a budget that is far from reality wastes time. If you share one, base it on a calculation and say which cost it covers, such as FOB. Our guide to FOB price in clothing manufacturing explains the term. State your preferred Incoterm using the rules published by the ICC Incoterms rules, and ask each supplier to quote on the same basis.
How each level of detail tends to affect a factory's reply
1 dot = low, 5 dots = high
| Quote can be compared | Speed of reply | Fewer follow-up questions | |
|---|---|---|---|
| Full brief with image, quantity and fabric | ●●●●● | ●●●●● | ●●●●● |
| Short message with image only | ●●●●● | ●●●●● | ●●●●● |
| Message with no detail | ●●●●● | ●●●●● | ●●●●● |

Protecting Your Design and Handling Confidentiality
A supplier brief often includes images or sketches that you consider valuable. Share only what the factory needs at this stage, and keep the most detailed files, such as full tech packs, for suppliers you are serious about. Some brands ask suppliers to sign a confidentiality agreement before sharing designs. The UK Intellectual Property Office, at UK Intellectual Property Office, publishes guidance on design rights and trade marks. This is not legal advice, so take advice if your designs are original and important to the business.
Most reputable factories treat customer designs as confidential as a matter of course, and building a relationship with clear terms is the best protection. Use the first conversation to learn how the factory handles samples, patterns and files, and record anything you agree in writing. Ask who will see your supplier brief inside the factory and whether samples are kept after the order, so you know where your designs go.
Sending a short brief first vs a full tech pack first
Short brief first
- Short brief: quick for the factory to read and judge
- Short brief: shares less of your design early on
- Short brief: easy to send to several suppliers
Full tech pack first
- Full tech pack first: allows a precise quote
- Full tech pack first: shows you are ready to produce
- Full tech pack first: shares more design detail before trust exists
A general comparison. Many brands send a brief first and the tech pack to shortlisted suppliers.
Comparing the Replies Fairly
When replies arrive, compare them against each other and against your brief. Check that each quote covers the same fabric, the same decoration, the same quantity and the same Incoterm. A lower price may hide a lighter fabric or a missing item. Put the replies in a table, add the points that differ and ask follow-up questions. Our guide to comparing two supplier quotations shows how to do this without losing track.

From Brief to Sample to Bulk
The supplier brief is the start of a sequence. After you choose a supplier, you move to samples, then fit comments, then a pre-production sample and finally bulk. Each stage should refer back to the brief and the tech pack, so the project stays consistent. Our garment sampling process guide explains the stages in order.
Using a supplier brief from first contact to order

Common Supplier Brief Mistakes
Most brief problems come from missing information or from asking for the wrong thing. The table below lists those that cost the most time.
Supplier brief mistakes and what to do
| Mistake | What goes wrong | What to do |
|---|---|---|
| No quantity given | The factory cannot price or judge the fit | Give a realistic quantity or range per style |
| No reference image or sample | Replies assume different products | Attach an image or reference garment |
| Different briefs to different suppliers | Quotes cannot be compared | Send the same brief to each |
| No reply format requested | Replies miss the details you need | List the items you want in the quotation |
| Unrealistic target price with no basis | Good suppliers decline to quote | Base any target on a cost calculation |

How Ruhrose Works From a Supplier Brief
Ruhrose develops hoodies, fleece, jersey, denim and woven casualwear with production in Bangladesh and UK buyer support. When a UK brand sends us a supplier brief, we read it against the reference garment, tell you what else we need to quote and talk through sampling before bulk. We do not publish prices, minimums or lead times here, because they depend on the fabric, the style and the quantity. To start, visit Ruhrose and send your brief and a reference garment.
