Why Your Bulk Order Doesn't Match the Sample (And How to Prevent It)
Matias Santos, Founder·
The sample arrived and it was right. The wash looked exactly like the reference. The stitching was clean, the label sat where it should. You approved it, paid the deposit, and felt good about the decision.
Eight weeks later the bulk order arrives and something is off. The wash is flatter. The collar sits differently. Half the units are missing the label that was sewn neatly into the sample. Nothing about the order was technically violated, but the product in your hands is not the product you approved.
This is one of the most common, and most preventable, problems in clothing production. It rarely happens because a factory set out to deceive anyone.
Why bulk doesn't match sample, even with good factories
The sample is handmade. The bulk run is not.
In most factories, samples are made by a senior pattern maker or the most experienced machinist on the floor, by hand, with as much time as it takes to get it right. Bulk production runs through a line at production speed, with multiple operators each handling a single repeated operation. A senior machinist sewing one garment carefully and a line of eight people sewing two hundred garments a day are not doing the same task, even when they're following the same instructions. Small variances in tension, seam allowance, and finishing are the normal cost of moving from craft to production, not a sign of bad faith.
Fabric lot variance
Dye lots vary, and GSM has a tolerance even within "the same" fabric, typically a few percent either way. If your sample was cut from one fabric delivery and your bulk order is cut from a different roll ordered weeks or months later, even from the same mill, the hand-feel, drape, and exact shade can shift slightly. This is industry-standard and unavoidable at the margins, the question is whether the shift stayed within an acceptable range or whether something changed structurally.

Specs that were never locked down
If your tech pack didn't specify exact tolerances, the sample maker used their own judgment to interpret what "correct" meant, and the bulk line used a different judgment, sometimes a different person entirely. A callout that says "ribbed cuff" without a stated width, gauge, or stretch recovery target leaves room for two different correct interpretations. This is the most common root cause, and it traces straight back to the completeness of the brief the factory was working from.
The version that is deliberate
Some sample-to-bulk mismatches are exactly what they look like: a factory shows its best work to win an order, then cuts corners once the deposit has cleared. This happens, and it's worth naming directly rather than pretending every mismatch is innocent. But in the corpus of mismatch complaints from founders, this is the minority case, not the majority one. Most of the time the problem is structural, not deceptive, which is good news, because structural problems are the ones you can prevent with process.
The sample type most brands skip, and the one that actually protects you
Not every sample serves the same purpose, and conflating them is where a lot of the risk hides.
A fit sample or proto exists to check the pattern and fit. It's often made early, sometimes before the final fabric has even arrived, and it is not meant to be your bulk quality reference.
An SMS, a sales sample, exists to show buyers or for your own marketing photography. It's frequently the most polished version a factory will ever produce, made by the best hands in the building, and treating it as your bulk benchmark sets an expectation the production line was never asked to meet.
The sample that matters most, and the one brands most often skip entirely, is the PPS, the pre-production sample. A real PPS is cut from the actual fabric lot that will be used for bulk, sewn using the actual line setup and operators who will run production, not the sample room's best machinist. If you've never explicitly requested a PPS and instead approved a fit sample or an SMS as your final reference, you have functionally approved a garment that no one on the bulk line was ever shown.
The final checkpoint, often skipped for the same reason, is the TOP sample, top-of-production, a handful of units pulled directly from the running bulk line partway through the order. This is your last chance to catch a drift before the full shipment is packed and gone.
What to actually do, in order
Step 1: Lock the spec before sampling, not after
Written measurements with stated tolerances, fabric composition with a GSM range, and explicit construction callouts go in the tech pack before the first sample round, not as feedback after something looks wrong. Every ambiguity left in the brief becomes a judgment call someone else makes for you.
Step 2: Ask directly whether your sample is cut from the bulk fabric lot
"Is this fabric from the same batch you'll use for bulk production, or a different one?" is a normal, expected question. A factory with nothing to hide will answer it plainly. If the answer is no, ask for a swatch from the actual bulk lot before you approve anything as final.
Step 3: Approve against the tech pack, in writing, with photos
"Looks good" is not an approval a factory can act on with precision. Reference specific measurement points, specific callouts, and attach photos with your sign-off. This becomes the document everyone, including you, gets held to later.
Step 4: Request a TOP sample before the order ships
A simple ask, "please send photos or a few physical units pulled from the production line before the full order ships," gives you a checkpoint while there's still time to fix something, instead of finding out after a container is already at sea.
Step 5: Tie final payment to that checkpoint, not to the order being placed
A payment structure where the balance releases on TOP sample approval, rather than simply on production start, gives both sides a shared reason to take that final check seriously. This is standard in staged payment structures and worth insisting on if your factory's default terms don't already include it.
When it's not a sample problem, it's a handoff problem
In many Portuguese family-run factories, the person who manages your sample correspondence during development is not the same person running the bulk line during production. This isn't a red flag on its own, it's how specialized roles work in a well-run operation, but it does mean your sample approval notes need to actually travel to the people executing bulk, not just sit in an email thread with the export manager. Ask plainly who runs quality control on the bulk line and whether they've seen your approved sample and your tech pack notes directly. If the answer is vague, that's the gap to close before production starts, not after.
The honest summary
A bulk order that doesn't match its sample is rarely a sign you chose the wrong factory. It's usually a sign that the sample everyone agreed on wasn't actually the one that predicts bulk output, the spec had soft edges that got interpreted differently twice, or the people running production never saw what was approved. All three are fixable before you pay a deposit, not after you've received a container that doesn't match what you thought you bought.
On NovaSupplier, every sample round, fit, PPS, or TOP, is logged against the same project and tech pack, with approval notes and photos kept in one thread, so what you signed off on is never in question by the time bulk production ships. Start at novasupplier.com**.
