Sourcing a product is not one job. It is eight of them, running in an order where each one constrains the next, and most of the cost is decided in the first four — before a factory has quoted anything. This is how we run them, what happens inside each, and what you decide.
The model in three parts
Demand, materials, production capacity and logistics still live in disconnected systems, and the decisions that connect them are usually coordinated across spreadsheets, mail threads and messaging apps. The reason we split the work three ways is that those three kinds of work fail for different reasons: searching and comparing is a scale problem, judging and negotiating is a judgment problem, and making things is a capability problem.
| Who | What it does | What it does not do |
|---|---|---|
| AI | Structures fragmented information, searches the vetted network, and compares many possible combinations of material, factory, quality plan and lane against your brief. | Decide. It never approves a recommendation and never commits you to anything. |
| Library of Trade experts | Evaluate what comes back, apply product judgment, negotiate, and are accountable for the chain they put in front of you. | Manufacture. They select and hold suppliers to a standard; they do not run the machines. |
| Supplier partners | Mills, factories, quality partners and logistics partners execute the work they were selected for. | Stay anonymous. You know who they are and you contract with them directly. |
The division is deliberate and it is the whole argument. Comparing a thousand combinations is work a person should not be doing by hand; deciding which of them a brand should actually commit to is work that should not be automated.
What Library of Trade is not
- Not a marketplace. There is no catalogue to browse and no listing fee. Work starts from a brief, not from a search box.
- Not a factory directory. We do not sell access to a supplier list. A list is the easy part of sourcing and almost never the part that goes wrong.
- Not a reseller. We do not buy your goods and sell them on with a margin, and we do not work by adding a markup to supplier pricing.
- Not a curtain between you and your suppliers. You contract directly with the factories and material suppliers, and you keep the relationship.
On money, once and plainly: brands do not pay membership fees, subscriptions or access fees. When suppliers receive qualified business through the network they pay an agreed administrative fee, so the service is funded by the supply side rather than by a traditional sourcing fee charged to the buyer. That is the whole of the commercial model as far as this article goes — the FAQ covers the rest.
The eight stages
The order matters more than it looks. Materials are chosen before the factory because the material usually sets more of the cost, the lead time and the compliance exposure than assembly does. Sampling sits before production because a specification is a description and a sample is the product. And logistics is last in sequence but first in modelling, because a lane you cannot afford invalidates a factory choice made three stages earlier.
| Stage | What happens | What you decide |
|---|---|---|
| 01 Brief | Requirements received, extracted and clarified | What the product has to be and cost |
| 02 Product Development | Specifications, tech pack, BOM, manufacturability review | The product definition |
| 03 Materials | Material search, comparison, specification and compliance review | The material selection |
| 04 Factory Matching | Search, RFQ, quotes, capacity and compliance checks, negotiation | The factory |
| 05 Sampling | Sample made, measured, reviewed, revised | Sample approval |
| 06 Production | Order placed, capacity and milestones managed, exceptions surfaced | Any change to scope or date |
| 07 Quality | In-line checks, final inspection, compliance verification | Whether the goods ship |
| 08 Logistics | Freight booked, export, customs, onward transport, delivery | Destination and delivery terms |
01 Brief
You define the product, the volumes, the target cost, the quality level, the timeline and the market requirements. A first brief is almost never complete, and that is normal — the work here is extracting the requirements from what you sent and coming back with the few questions that actually change the answer: which market it is sold in, what the product has to survive, what the price has to be for your pricing to work. You get back a structured brief you recognise as yours, with the gaps named rather than assumed away.
02 Product Development
The brief becomes a definition a factory can quote and build: specifications, a tech pack, a bill of materials, and a manufacturability review that catches the details which make a product expensive to produce for no benefit to your customer. This is also where the honest conversation about target cost happens, because the design decides most of it. You receive the specifications and the tech pack, and you decide what the product is.
03 Materials
Materials, components and trims are searched and compared before the factory is chosen — on price, availability, performance, and the documentation a supplier can actually produce rather than claim. A specification review and a compliance check run over the shortlist, because a material that cannot be evidenced is a material that will fail somewhere later. You approve the material selection.
04 Factory Matching
Factories are matched on capability, price, capacity, quality history and compliance — not on who replies fastest. The work is a search across the vetted network, an RFQ written so that quotes come back comparable, the supplier questions that follow it, capacity checks against your timeline, a cost comparison on delivered cost rather than unit price, compliance checks, a shortlist, and then negotiation. You see the shortlist with the reasoning, and you choose the factory.
05 Sampling
The sample is where the specification meets reality, and it is the cheapest place to find out that the two disagree. Samples are requested, received, measured, reviewed for fit and construction, commented on, and revised until the physical product matches the definition. Sample approval is yours alone, and nothing goes into production against an unapproved sample.
06 Production
The order becomes a purchase order and a production plan: capacity booked, materials confirmed, milestones agreed, then progress followed through the real stages of making the product. The part that earns its keep is exception monitoring — learning that a material is late or an output is behind while there is still time to do something, rather than at the ship date. You get updates against the plan you agreed, not reassurance.
07 Quality
Production is inspected against the agreed specifications, tolerances and quality standards: in-line checks while there is still time to correct, a final inspection at the end, a review of the result against the sampling plan you agreed, and verification of the compliance requirements your market needs. Shipment approval follows the inspection result — you decide whether the goods ship.
08 Logistics
Freight is booked, goods are collected, exported, moved, cleared and delivered to your warehouse or fulfilment centre, with the documentation each of those steps requires. This is also where the landed cost modelled at the brief becomes the landed cost you actually paid, which is the comparison worth making before the reorder — see what landed cost includes.
Where you stay in control
End-to-end management is not the same as handing over the decisions. Five of the eight stages end in something only you can approve, and they are the five that cost money to get wrong.
- The product definition, the tech pack and the specifications. Your designs and product information remain yours.
- The material selection, with the comparison that led to it.
- The factory, with the shortlist and the reasoning behind the recommendation.
- Sample approval — the gate production cannot start without.
- Shipment approval, after the inspection result.
Briefing, following and approving happen in one place rather than scattered across a mail thread, which is less a feature than a precondition: an approval that only exists in somebody's inbox is not a record of a decision.
- What a brief needs before we can do anything useful with it
- The product: what it is, what it must do, and any reference sample or competitor product you already have.
- Volumes: the first order, and what you expect to repeat.
- Target cost: landed where you take delivery, and what it has to be for your pricing to work.
- Target timeline: the date that actually matters, and why it matters.
- Quality requirements: the level you are selling at, and what a defect costs you with your customer.
- Compliance and sustainability requirements: the market you sell into, and anything your retail or platform channel demands.
- Anything already fixed: an existing supplier, a material, a pack format, a certification you have to carry.
What this does not cover
- Consumer product categories — apparel and accessories, bags, jewellery, packaging, home and living, beauty and personal care, pet, baby and kids, kitchen and dining, travel, sport and outdoor, promotional products. Nothing ingestible, nothing pharmaceutical.
- We are not your customs broker, your testing laboratory or your legal adviser. We work with those parties and we do not replace them.
- We do not decide what you should sell. The commercial judgment about the product and the market stays with you, because you are the one carrying it.
Why this shape
Two things follow from running all eight stages rather than one. The first is that the biggest opportunities in sourcing sit before production begins — in the design, the material and the choice of chain — which is exactly where a brand working stage by stage has the least help. The second is that factory price is only one part of total product cost, so the cheapest factory is rarely the best answer: materials, production, quality, freight, duties and delivery all move together, and optimising one of them in isolation usually just moves the cost somewhere less visible.
