FlowMarket
Where to find contract manufacturers: FlowMarket is a B2B sourcing network powered by an AI agent. You describe the part and the programme — process, material, tolerance, annual volume, certification — and the agent matches you with contract manufacturers set up for exactly that work, then requests quotes and lead times so you can compare capability and price side by side instead of qualifying shops one at a time.
Sourcing a contract manufacturer
Contract manufacturing is a relationship, not a transaction, and that is what makes the search hard. A shop that quotes your part competitively may be wrong for you in every other respect: no capacity in the quarter you need it, no experience with your material, no quality system your customer will accept. None of that is visible in a price. It surfaces three months in, when the first production batch slips.
So the qualifying work is the real work, and it is mostly repetition — the same drawings, the same volumes, the same questions about certification, sent to shop after shop. Describing the programme once and letting an agent carry it to manufacturers who already run that process at that scale removes the repetition, and the mismatches come back early rather than after the tooling is cut.
What kind of partner you are actually looking for
Naming the depth of the relationship narrows the field faster than naming the process does.
- Build to print — you own the design and the drawings; the shop manufactures to them. Fastest to quote, easiest to second-source, and the right model when the design is settled.
- Build to spec — you define function and requirements, the manufacturer engineers the part. Slower to start, but the shop's process knowledge lands in the design.
- Full-service manufacturing — machining, finishing, assembly, test and packing under one order, so you receive a finished item rather than managing four suppliers and the logistics between them.
- Capacity partner — a second source that runs the same part as your primary, qualified in advance, for peaks and for the week your main supplier goes down.
What decides whether a shop can actually take the job
- Volume band — a prototype shop and a shop running 100,000 pieces a year are different businesses with different cost structures. Quoting outside their band gets you a polite, expensive number.
- Certification — ISO 9001 is the floor. IATF 16949, AS9100, ISO 13485 and EN 1090 each gate entire industries, and no amount of capability substitutes for the certificate.
- Process depth in-house — every step a shop subcontracts adds lead time and a handover. Ask which operations happen under their own roof before comparing prices.
- Capacity now — the machine list tells you what a shop can do, not what it can start. Available capacity in your window is a separate question and worth asking first.
What contract manufacturing costs
A contract manufacturing price is piece price plus everything around it: tooling and fixtures, first article inspection, qualification samples, minimum order quantities, packaging, and the freight terms. Two quotes that look 15% apart on piece price routinely land level once tooling is amortised over the first year — and the cheaper piece price is sometimes the one with a minimum order that ties up a quarter of working capital.
Comparing on total landed cost per year, not per piece, is the only comparison that survives contact with the first order. It is also the comparison suppliers rarely volunteer, so it has to be asked for explicitly in the enquiry.
How the AI agent matches manufacturers
The agent reads your requirement rather than your keywords. It searches the FlowMarket network and connected industrial directories together, scores every candidate on how well it answers what you actually described — process, volume, certification, geography — and drops anything that does not clear the bar. Each match comes back with a plain-language reason for why it is there, which tells you more in one line than a capability page does in ten.
When to source locally and when not to
Distance costs more than freight. It costs response time when a drawing changes, travel when a first article fails, and weeks of transit inventory you have to finance. For high-mix, low-volume work with an evolving design, a shop you can reach in a morning usually wins on total cost even at a higher piece price. For settled, high-volume parts the calculus flips. Describe your case and the agent weights the match accordingly rather than defaulting to nearest or cheapest.
