The short answer
Contract manufacturing is an arrangement in which one company owns a product’s design and sells it, and hires another company to make it to that design. It is a division of labour, not a type of factory. One side owns the drawings, the specification and the brand; the other side owns the shop floor.
When the U.S. Bureau of Labor Statistics worked through how to classify firms that outsource production, it split the same arrangement in two: a party that owns the design or intellectual property and sells the finished product, and a “manufacturing service provider” that transforms material inputs “according to the contract specifications”. That second party is the contract manufacturer. The words put a name to how most physical products are actually built: the company selling the product rarely owns every machine it needs — injection moulding, CNC machining, sheet-metal work, anodizing, circuit-board assembly — so it places the work with a shop that already runs those processes well.
The words people mix up
Three terms get used interchangeably, and the difference comes down to one question: whose design is it?
Contract manufacturing vs. private label
In contract manufacturing, the buyer brings the design or specification and the factory builds to it. In private label, the factory already makes a product and the buyer sells it under its own name and packaging. Put plainly: contract manufacturing is build-to-spec; private label is putting your name on an existing product. The first gives you something that is genuinely yours; the second is faster because nothing is designed from scratch.
Contract manufacturing vs. an OEM’s own product
“OEM” is used loosely, but the useful contrast is this: a company designing and selling its own product is making its own goods; when that same company makes a product to another firm’s design, it is acting as that firm’s contract manufacturer. The role depends on the deal, not on the building — a shop can sell its own line one day and take contract work the next. The dividing line is always who owns the design and the brand.
Contract manufacturing in regulated industries
In pharmaceuticals and medical devices the same shape appears under the name contract manufacturing organization (a CMO, or a CDMO when development is included). U.S. Food and Drug Administration guidance on contract manufacturing arrangements for drugs separates the “owner” from the “contract facility” that does the work, and is explicit that the owner stays responsible for the product even though another company runs the line. The lesson generalises beyond drugs: outsourcing the making does not outsource the accountability.
What a brief and a quote usually contain
A job starts with a brief from the buyer and comes back as one or more quotes from factories. You can see the fields both need in any public quoting flow. Xometry’s, for example, asks the buyer to specify the manufacturing process, material, finish, quantity and inspection or certification requirements, then returns pricing and a lead time, with one-time tooling tracked as its own line item. A brief and a quote are the two halves of that exchange.
A brief (what the buyer states)
- The part, with a drawing or specification, its material and tolerances.
- The process it needs — for example CNC milling, injection moulding, sheet metal.
- Quantity: a first run, and any repeat volume expected.
- The date it is needed by.
- Any finish, inspection, certification or origin requirement.
A quote (what the factory answers)
- A unit price at a stated quantity.
- Any one-time tooling or setup cost, quoted separately.
- A lead time to first delivery.
- A minimum order quantity.
- The assumptions behind the number — materials, finishing, what is and isn’t included.
A quote is an offer to make the part on those terms. It is not a purchase order and not a contract on its own; the buyer and the factory still agree price, terms and delivery between themselves before anything is built.
What a group of factories needs to answer briefs well
A single shop can read an email and write a quote. A group of factories — a cooperative, a manufacturing association, a regional network, or one shop that works with trusted partners — has a harder job, because a brief has to reach the right shops, get assigned, and come back as responses a buyer can actually compare. In practice a group needs to be able to:
- Receive a brief in one place and one shape, not scattered across inboxes, calls and spreadsheets.
- See which factories fit — by capability, lead time against the buyer’s date, spare capacity and minimum order — with the reasons visible.
- Assign the brief to one factory or several, and know who is working on what.
- Compare quotes on the same terms — price, tooling, lead time — so the choice is easy to explain.
- Record the decision once a quote is chosen, while price, terms and delivery stay between the buyer and the factory.
None of this creates demand. Grouping factories does not conjure buyers; a network brings buyers through its own relationships and outreach. Software just makes each brief the network already receives faster to route and easier to answer well.
Where Moxlet fits — and where it does not
Moxlet is software for an existing factory group. It gives a factory or a factory network a branded directory and a shared workflow for exactly the loop above: receive a buyer’s brief, check it, see which factories fit with the reasons shown, collect quotes, and compare them side by side. When a quote is chosen, Moxlet records that award as a decision.
What Moxlet does
- Gives your network a branded directory at its own address.
- Takes in a buyer’s brief and keeps it in one shape.
- Ranks the factories that fit and shows why.
- Lets operators assign a brief and collect quotes.
- Puts quotes side by side so they are easy to compare.
- Records one award as a decision, which an operator can void.
What Moxlet does not do
- It does not manufacture anything itself.
- It is not a contract manufacturer and not a job board.
- It does not take payment, and buyers pay Moxlet nothing.
- An award is not a purchase order and moves no money.
- It does not verify capacity or certify suppliers.
- It does not decide where products are made.
Capabilities, capacity and lead times on Moxlet are what members declare, shown as declarations rather than certificates; buyers confirm what they need directly with the factory. Origin claims stay with the maker: a “Made in USA” claim, for one, has to meet the FTC’s standard that a product be “all or virtually all” made in the United States, on a reasonable basis, and Moxlet never makes that claim on anyone’s behalf. The network sets its own commission on awarded work and pays Moxlet a plan fee and a success fee when work is awarded — recorded as ledger lines and settled by bank transfer, never charged to a card. The price sheet has the exact numbers.
In one line: contract manufacturing is one company making another company’s product to its design. Moxlet is the shared workspace a factory group runs on to receive those briefs, route them, and compare the quotes that come back. It supplies the software; the factories, the network and the buyers own their commercial relationships.
