The short answer: to find a clothing manufacturer for a startup, write a tech pack for the garment, decide your quantity and whether you want domestic or overseas production, then shortlist factories that take your minimum order quantity and make your garment type. Startup-friendly US factories now run 50 to 250 units per style; small cut-and-sew studios will do 1 to 50 for samples at a higher unit cost. Send the same tech pack to every factory so quotes and samples are comparable, and verify each one before you commit.
The reason this feels so hard is that the factories built for small brands almost never rank in search. The first pages you find are directories padded with trading offices that subcontract the sewing, and the plants that do rank quote a minimum of a thousand pieces per style before you have sold a single shirt. Here is the process that actually gets a first run made.
Start with a tech pack, not a factory search
Every serious clothing manufacturer works from a tech pack. It is the spec sheet that carries your measurements, points of measure, stitch types, trims, labels, fabric, and construction notes. It is the source of truth for both the sample and the graded size run, and it is what makes two factory quotes comparable in the first place.
Without one, each factory guesses at the details and quotes a slightly different garment, so their prices and lead times cannot be lined up against each other. If you do not have a tech pack yet, an independent pattern maker or many factories can build one from a reference sample you supply. Do this before you send a single inquiry, because it is the difference between five comparable bids and five estimates for five different products.
Know which low-MOQ tier your budget buys
Minimum order quantity is where most first-time founders get surprised. Low MOQ is not one number; it comes in three practical tiers, and each one is a different kind of shop.
| Run size per style | Who makes it | Per-unit cost | Best for |
|---|---|---|---|
| 1 to 50 units | Sample room, small cut-and-sew studio | Highest | Proof of concept, buyer samples, line sheets |
| 50 to 250 units | US small-batch factory | Falling | A startup launching its first styles |
| 250 to 1,000 units | US mid-volume factory | Lower | Scaling a style that already sells |
| 300 to 1,000+ units | Overseas factory | Lowest at volume | Unit cost once demand is proven |
The 50 to 250 unit tier is the domestic small-batch sweet spot, and it is where most startup-friendly US factories sit. Below that you are paying sample-room prices; above roughly 500 units overseas production usually wins on unit cost because setup and labor spread across more pieces. Decide which tier your launch budget buys before you ask anyone for a quote, so you only contact factories that fit.
Domestic or overseas is a cash-flow decision
US factories generally support lower minimums and shorter lead times, roughly 6 to 12 weeks against 16 to 24 overseas. That lets a young brand order what it can realistically sell and reorder quickly when a style moves. The trade is a higher per-unit cost, and that gap is widest at low volumes because the fixed costs spread across fewer garments.
Overseas factories win on unit cost once volumes pass about 500 units and often keep dyeing, printing, finishing, and packing under one roof. The trade is longer timelines, higher minimums, time-zone friction, and freight and customs. Many brands stay domestic for the first cycle or two, prove the demand, then move volume offshore. As you plan those first cycles, it pays to track what each style actually earns so a reorder decision rests on real sell-through, not a hunch.
The questions that separate a factory from a middleman
The single biggest risk for a new brand is paying a trading office that quotes you and then subcontracts the sewing to a floor you never see. A few direct questions flush most of them out.
Ask to see the sewing floor on a video call. Ask which similar garments they run in volume today. Ask for the MOQ per style and per color, because fabric and dye minimums often sit below the sewing minimum and change the math. Ask who buys the fabric, you or the factory. Ask for the sample lead time and cost, and whether the sample fee credits against production. A factory running its own line answers these plainly and offers references; a broker gets vague.
Send one brief to several factories and compare
Once you have a shortlist of factories that make your garment type and take your quantity, send every one of them the same tech pack and the same quantity, and ask each to quote the sample cost, the per-unit production cost at two or three volumes, the lead time, and the fabric minimum. Identical inputs are what let you compare the outputs.
Watch for the shape of the price curve, not just the headline number. A factory that is a little more expensive per unit but delivers in half the time and takes a quarter of the minimum can be the cheaper choice for a first run, once you account for the inventory you are not stuck holding.
Verify before you wire a deposit
Before money moves, confirm the factory is what it claims. Check business registration, look for a WRAP certification or a recent social compliance audit for ethical production, and OEKO-TEX for fabric safety. Order a paid sample and inspect the construction against your tech pack. Treat any certificate a factory shows you as a signal to confirm at the source, not as proof on its own.
This verification step is exactly where an AI sourcing agent saves a startup weeks. Describe the garment, your quantity, and whether you want domestic or overseas production, and our clothing manufacturers shortlist returns apparel factories that fit, with minimum order quantities, lead times, capabilities, and identity and registry verification laid out side by side. If you are still deciding how many units to commit to, our guide on what MOQ means and how to lower it walks through the levers, and domestic vs overseas manufacturing covers the cost and lead-time trade in depth.
The takeaway
Get the tech pack right, pick the MOQ tier your budget can actually fund, decide domestic or overseas on cash flow rather than sticker price, and send one identical brief to several verified factories. Do that and finding a clothing manufacturer stops being a gamble and becomes a comparison you can win.
