What Does “Bulk” Mean in Clothing Manufacturing?
There is no official quantity that makes an order “bulk”. In practice, bulk production means the main production run of a style after samples have been approved, as opposed to development samples. For a start-up that might be a few hundred pieces per style; for an established brand it could be thousands. What defines bulk is the process: production begins only after the pre-production sample is signed off, the fabric is bought in volume, the garments are cut in layers and sewn on a production line, and the order is inspected, packed and shipped as a batch.
This guide covers that process from the brand's side. For the factory's side, see our guide to the garment production process. If you do not yet have a manufacturer, start with how to find a clothing manufacturer.
Step 1: Lock the Specification
Everything in bulk production traces back to what you specified. Before you ask for a bulk quote, make sure you have a complete tech pack covering the construction, measurements and grading, fabric composition and weight, colours with references, trims and labels, branding artwork and placement, and packaging instructions. Add the quality standard you expect, the test requirements and any compliance requirements for your market. Changes after bulk starts are costly, and changes after cutting are often impossible.
Step 2: Approve a Pre-Production Sample
The pre-production sample (PPS) is made in the bulk fabric and on the bulk line, and it is the reference for everything that follows. Check measurements against the spec, fabric hand-feel and weight, colour against the approved reference, stitching and finishing, labels and branding, and wash performance after laundering. Sign and date the approval, and ask the factory to retain a matching sample for the inspector. If anything is wrong, request a revised sample rather than accepting “we will fix it in bulk”. Our sampling guide explains the sequence.
Step 3: Get a Firm Bulk Quote
A bulk quote should state the unit price at your quantity, the exact specification it covers, the fabric and trims included, the Incoterm and port, the lead time, the payment terms and the validity period. Check what the price includes: packaging, labels, hangtags, testing, inspection and export documents. Compare against the landed cost you need to hit, using our pricing guide and cost guide. If the price is higher than you can afford, change the specification or the quantity rather than hoping the factory will absorb the difference.
Step 4: Decide Quantities, Sizes and Colours
The number you order, and how you split it across sizes and colours, determines your cash outlay and your sell-through. Check the factory's minimums per style and colour, as explained in what is MOQ in clothing manufacturing. For a first order, fewer colours with more depth is safer than many colours at the minimum. For the size split, a common starting point for adult unisex garments is a bell curve centred on the middle sizes, adjusted using your own audience data. Add a small allowance for production defects, commonly a percentage of the order, and agree whether the factory will make up any shortfall.
Step 5: Issue a Purchase Order and Agree Terms
A purchase order (PO) turns the quote into a commitment. It should reference the tech pack version and approved sample, quantities by size and colour, unit price and currency, delivery date and place, Incoterm, payment schedule, quality standard and inspection rights, packing and labelling requirements and remedies for delay or defects. Have the factory confirm it in writing, and keep every version. Our guide to payment terms with clothing manufacturers explains how to structure deposits and balance payments safely.
Step 6: Confirm Materials and Test Them
After the deposit, the factory buys or produces the fabric and trims. This is the stage to check what has arrived: fabric weight, composition, colour and shade consistency, and trim quality. For critical fabrics, request test reports on shrinkage, colour fastness and pilling before cutting begins; see our garment testing guide. If the fabric fails, the cost of replacing it is far lower before cutting than after sewing.
Step 7: Monitor Production
Agree a production calendar with milestone dates for materials in house, cutting, sewing start, sewing complete and packing. Ask for short progress updates with photos at each stage, and schedule an inline inspection when roughly a fifth to half of the order has been sewn, so that problems are caught while the line can still correct them. Typical issues include shade variation, mis-set labels, misplaced prints and measurement drift. Keep communication factual and in writing, and respond quickly to questions, since waiting on your approval is one of the most common causes of delay.
Step 8: Inspect Before You Pay the Balance
A final random inspection when the order is substantially complete and packed tells you whether the goods meet your quality standard. Use a recognised sampling plan, such as the one in our AQL inspection guide, and have an independent inspector check measurements, workmanship, labelling, packaging and carton quantities against the approved sample. If the batch passes, release the final payment as agreed. If it fails, agree rework or replacement, re-inspection and a revised ship date before any more money moves.
Step 9: Ship and Clear Customs
Depending on the Incoterm, either the factory or you will arrange the freight. Book space early, prepare accurate commercial documents and agree who handles export and import clearance. For the UK, see our guide to importing clothing from Bangladesh, which covers EORI, commodity codes, duty and VAT. Insure the shipment and track it to delivery, and plan a day or two after arrival for checking, labelling corrections and putting stock into sale.
Step 10: Review and Reorder
Once the goods arrive, check them against the PO and the sample, record any defects with photos and share your findings with the factory in writing. Track sell-through by size and colour, which is the best data you will ever have for your next order. Reorders are quicker and cheaper than first orders because development is done, so reorder winners and drop the rest. This is the core idea behind test and scale manufacturing.
Example: Splitting 500 Pieces by Size and Colour
Suppose you order 500 hoodies in two colours. Rather than splitting everything evenly, you might put 60% in your best-selling colour and 40% in the second. For a unisex adult range, a starting split across sizes might be roughly 10% S, 30% M, 35% L, 20% XL and 5% XXL, but this is only a starting point: if you already have customer data, use it. Retailers' returns data and your own pre-orders are far better guides than any generic table. An example of the arithmetic follows.
| Colour | S | M | L | XL | XXL | Total |
|---|---|---|---|---|---|---|
| Black (60%) | 30 | 90 | 105 | 60 | 15 | 300 |
| Sage (40%) | 20 | 60 | 70 | 40 | 10 | 200 |
| Total | 50 | 150 | 175 | 100 | 25 | 500 |
Illustrative only. Check that each colour meets the factory's colour minimum before you commit.
Why Bulk Can Differ from the Sample
Brands are often surprised when bulk garments differ slightly from the sample. The usual causes are a different fabric lot with a small shade or weight variation, a sample made by a skilled sample-room technician rather than a production line, and changes made to speed up or cheapen the process. You can limit this by approving a pre-production sample made on the production line, asking for lab dips or shade bands for coloured fabrics, setting tolerances for measurements and colour in the purchase order, and carrying out an inline inspection. Where the difference is outside the agreed tolerance, you have a basis for rework; where there are no tolerances, you do not.
Partial Shipments and Late Orders
Occasionally a production run falls behind. Agree in advance what happens: whether the factory may ship in parts, who pays for air freight to recover time and whether you may cancel or claim a discount if the delay exceeds an agreed number of days. These terms are easiest to agree before the order, when both sides want the business. If delays do happen, ask for a revised production calendar in writing and check whether quality is being sacrificed to catch up.
A Sample Bulk Production Timeline
| Week | Milestone |
|---|---|
| 0 | PO confirmed and deposit paid |
| 1–3 | Fabric and trims sourced, tested and approved |
| 3–4 | Marker making and cutting |
| 4–7 | Printing or embroidery, sewing and inline inspection |
| 7–8 | Washing, finishing, packing and final inspection |
| 8–9 | Balance paid, goods handed to forwarder |
| 9 onward | Sea or air freight, customs and delivery |
This is an illustration, not a promise. Real timelines depend on the factory, product and season, and our lead times guide gives more detail.
Mistakes to Avoid
- Starting bulk without an approved pre-production sample.
- Changing the specification after cutting begins.
- Paying the balance before inspection.
- Ordering too many colours and sizes in the first run.
- Forgetting labelling and compliance requirements until the goods arrive.
- Having no written agreement on defects, delays and rework.
