From sample to bulk production, the journey runs through eight stages: brief, first sample, revision, pre-production sample, specification freeze, bulk production, inspection, and freight. Sampling takes 6–10 working days (12–15 for complex constructions); once the pre-production sample is approved, bulk runs 35–50 days, is inspected against AQL 2.5 under ISO 2859-1, and ships FOB Xiamen with a standard 30% deposit and 70% balance before shipment. The 500-piece MOQ per style and colourway applies from the bulk stage onwards, not to the samples themselves.

Most buyers understand sampling and most understand shipping. Fewer see clearly how one becomes the other. The transition from an approved prototype to a released production order is where a programme is either controlled or left to chance, because it depends on documents, tolerances and a frozen specification rather than on good intentions.
This article walks the full route in order, stage by stage, explaining what happens, who decides, and where the schedule can slip. It is written for a brand owner or programme manager who wants to see the whole path before committing capital to it.
The Journey at a Glance: Eight Stages from Brief to Shipped Stock
The whole journey is easier to plan when it is visible end to end. The table below sets out the eight stages, the working window each occupies and the decision that closes it. Total elapsed time from brief to shipped stock is typically eleven to fourteen weeks for a single style.
| Stage | Activity | Window | Closing decision |
|---|---|---|---|
| 1 | Brief and specification | 3–5 days | Brief approved |
| 2 | First sample | 6–10 days | Sample reviewed |
| 3 | Revision round | 6–10 days | Details refined |
| 4 | Pre-production sample | 5–8 days | Golden sample signed |
| 5 | Specification freeze | 1–2 days | Bulk released |
| 6 | Bulk production | 35–50 days | Run completed |
| 7 | Inspection | 2–4 days | AQL 2.5 passed |
| 8 | Freight and delivery | 5–30 days | Goods received |
Stages 1–2: Brief and First Sample
The journey begins with a written brief and ends its first phase with a physical sample. The brief is the specification in words and drawings; the sample is that specification made real. Everything downstream depends on the quality of these two artefacts.
- Translate the design into a dimensioned sketch with height, width, depth and drop.
- Name the leather or fabric family and a reference swatch code.
- Specify hardware by finish and size, and confirm availability.
- State the tolerance acceptable on each key measurement.
- Confirm the lining, thread and edge finish for the sample.
- Approve the brief before pattern work begins, so the clock is honest.
The first sample arrives within 6–10 working days once the brief is approved, or 12–15 days for complex constructions such as framed bags or multi-panel travel shapes. This is the moment to test the pattern, the silhouette and the proportions as objects rather than ideas. Feedback should be collected into a single annotated pass, because scattered comments across several emails produce interpretation rather than instruction.
It helps to review the first sample against the brief line by line. Does the handle drop match the figure you wrote down? Does the gusset hold its shape when the bag is loaded? Does the lining sit flat at the corners? A structured review turns a subjective reaction into a list of specific corrections, and a specific list is what the revision round can act on. Vague praise or vague criticism costs a round either way.
Founders often ask whether the first sample should look finished. It should not. The first sample exists to answer questions, and a piece that is visibly a prototype is doing its job. What matters is that the questions it answers are the ones the brief posed, and that the corrections it reveals are recorded before the design moves forward.
Stages 3–4: Revision and Pre-Production Sample
The revision round corrects details without reopening the structure. Its output feeds the pre-production sample, which is made from the actual bulk materials and becomes the golden reference. Two points along the journey are worth pausing on: the discipline of staying within the structure, and the value of producing the pre-production sample in the real material.
| Element | First sample | Pre-production sample |
|---|---|---|
| Material | May be a representative stock hide | Actual bulk material |
| Purpose | Prove the pattern and silhouette | Freeze the specification |
| Hardware | Intended fittings where possible | Final production hardware |
| Branding | Placeholder acceptable | Final logo, die and placement |
| Outcome | Reviewed and refined | Signed and archived |
The pre-production sample is the most consequential single artefact in the entire programme. It is the last chance to catch an incompatibility before cutting begins, and the definitive answer to any later question about what was agreed. Brands that treat it as an optional formality discover the value of it only when something goes wrong at the bulk stage.
Stage 5: Freezing the Specification
Between the approved pre-production sample and the released bulk order sits a short, decisive stage: the specification freeze. Nothing is manufactured here, but everything is decided. The freeze converts an approved object into a set of instructions that the production floor will follow for the entire run.
A change made after the freeze is not a refinement; it is an amendment with its own impact on cost and schedule. Recording such changes formally, rather than absorbing them informally, is what keeps a programme honest. Most bulk-stage disputes trace back to a specification that was never truly frozen, or to a change that was agreed verbally and forgotten.
Stage 6: Bulk Production
Bulk production is the longest stage, running 35–50 days after sample approval. The standard minimum is 500 pieces per style and colourway. During this window the pattern is graded, material is cut in markers, panels are skived and prepared, and the bags are assembled across the line in a sequence designed for consistency.
| Sub-stage | What happens | Quality focus |
|---|---|---|
| Material intake | Hides and linings received and checked | Colour and grain consistency |
| Cutting | Markers laid and panels clicked | Yield and panel clarity |
| Preparation | Skiving, edge prep, hardware prep | Thickness and alignment |
| Assembly | Panels, linings and hardware joined | Stitch density and structure |
| Finishing | Edge finish, cleanup and checks | Uniformity across units |
A production floor running to a verified capacity of 200,000 pieces per month, as at our SGS-verified floor in Quanzhou (4,950 m²), schedules work in waves so that each style receives a consistent team and machine set-up. Consistency across a run depends less on individual skill than on standardising the construction so that every unit is built the same way.
Material intake is the sub-stage buyers most often overlook. When several hides are used for a single style, visible variation between them can appear across a batch even though each hide is individually acceptable. Setting a colour and grain tolerance at the freeze, and sorting hides before cutting, is what keeps a run visually coherent. A batch that looks uneven reads as lower quality even when every unit passes its dimensional checks.
Daily or weekly production updates keep a buyer informed without requiring a site visit, and they surface a slip early enough to react. A partner that reports progress against the plan, rather than only at completion, gives a brand the chance to adjust downstream commitments — photography, marketing, distribution — before a delay becomes a crisis.
Stage 7: Inspection and Quality Control
Inspection is where the bulk run is measured against the standard the sample set. It is not a search for perfection; it is a statistical check that the batch meets an agreed quality level. The standard used is AQL 2.5 under ISO 2859-1, single sampling at general level II.
| Check | Method | Standard |
|---|---|---|
| Dimensions | Measured against the golden sample | Within agreed tolerance |
| Materials | Verified against the frozen spec | Bill of materials |
| Stitching | Inspected for density and integrity | Construction spec |
| Hardware | Function and fixing tested | Final fittings |
| Branding | Placement and depth confirmed | Approved proof |
| Finish | Edge and surface checked | Uniformity across units |
Where a partner offers third-party inspection, it adds an independent layer of assurance for larger or higher-value orders. The purpose of the stage is not to reject work but to catch defects before they leave the floor, when correction is affordable. A batch that passes inspection and matches the golden sample is a batch that will not disappoint the end customer.
Stage 8: Packing, Freight and Delivery
The final stage moves finished goods from the floor to the buyer. Packing protects the product in transit; freight delivers it on the agreed terms. The commercial terms are settled well before this point, but they matter here because they determine when the balance falls due and who carries the risk along the route.
| Term | Meaning | Who arranges |
|---|---|---|
| FOB Xiamen | Standard basis; risk passes at the port | Buyer arranges onward freight |
| EXW | Collected from the production site | Buyer arranges everything |
| CIF | Cost, insurance and freight included to port | Partner arranges to destination port |
| DDP | Delivered duty paid to the buyer's address | Partner arranges door to door |
Payment follows the same rhythm across the journey: a 30% deposit releases the order, and the 70% balance is due before shipment, quoted FOB Xiamen with EXW, CIF and DDP available on request. Understanding the terms at the start of the journey, rather than at the end, lets a brand forecast its cash position accurately across the eleven to fourteen weeks.
Where the Journey Slips: Timing Risks and Buffers
The journey rarely fails at a single dramatic point; it slips in small increments. Knowing where the slippage occurs lets a brand build the right buffers into the calendar without padding every stage indiscriminately.
| Risk point | Typical delay | Buffer strategy |
|---|---|---|
| Incomplete brief | 1 week | Finish the spec before ordering |
| Extra revision rounds | 1–2 weeks | Cap rounds in writing |
| Material shortage | 1–3 weeks | Confirm availability early |
| Hardware lead time | 2–4 weeks | Verify fittings during sampling |
| Peak season load | 2–3 weeks | Book production slots early |
| Freight congestion | 1–2 weeks | Add a buffer before the launch date |
The most effective single buffer is a complete brief, because it eliminates the largest and most common delay. The second is early confirmation of materials and hardware, since these sit outside the production schedule and cannot be compressed once a shortage emerges. Beyond those two, a general buffer of one to two weeks before a fixed launch date absorbs the ordinary friction of freight and inspection.
A journey planned this way is dull, and that is the point. The brands that move from sample to shipment smoothly are rarely the ones with the most exciting designs; they are the ones whose specifications were complete, whose materials were confirmed early, and whose launch dates carried a small, deliberate buffer. The eight stages above are not a obstacle course to be survived but a sequence to be scheduled, and every stage rewards the same habit: decide precisely, then hold the decision steady until the next stage begins.
For a first programme, the temptation is to compress the front end — to skip a document or shorten a brief — in the belief that speed comes from starting sooner. In practice, speed comes from starting better. A complete brief and a confirmed material list at stage one are what allow stages six and seven to run at their standard 35–50 day pace without the interruptions that turn a schedule into a scramble.

Frequently Asked Questions
How long does it take from sample to bulk production?
The full journey typically runs eleven to fourteen weeks. Sampling takes 6–10 working days, or 12–15 for complex constructions, followed by a revision round and a pre-production sample. Once the specification is frozen, bulk production runs 35–50 days, then inspection and freight add a further few weeks. Planning from the delivery date backwards, rather than from the brief forwards, is the most reliable way to keep the schedule realistic.
What are the stages between a sample and a bulk order?
There are eight stages: brief and specification, first sample, revision round, pre-production sample, specification freeze, bulk production, inspection, and freight. The brief produces the first sample; the revision refines it; the pre-production sample freezes the standard; the freeze releases bulk; production runs; inspection checks the batch; and freight delivers it. Seeing all eight together makes the total lead time and the points of risk visible.
What is a pre-production sample and why does it matter?
A pre-production, or golden, sample is made from the actual bulk materials and confirms that the design still works when produced from the hides, linings and hardware the run will use. It is the last checkpoint before cutting begins and the reference standard for the whole batch. Brands that skip it discover any material incompatibility on the production floor at full scale, when correction is most expensive.
What is the minimum order for bulk production?
The standard minimum is 500 pieces per style and colourway, applied at the bulk stage. The MOQ does not apply to the samples themselves, so a brand can approve a single reference piece before committing to the full quantity. Where a buyer wants to test a concept before a full run, a small-batch pilot can be arranged below the standard minimum before scaling up.
How long does bulk production take after sample approval?
Bulk production runs 35–50 days after the sample is approved and the specification is frozen. The window covers material intake, cutting, preparation, assembly and finishing, scheduled in waves so each style receives a consistent team and machine set-up. Confirming material and hardware availability before releasing the order is what keeps the run inside that window rather than extending it.
How is quality checked during bulk production?
The bulk run is inspected against AQL 2.5 under ISO 2859-1, single sampling at general level II. This is a statistical check that the batch meets the agreed quality level, measured against the approved golden sample. Dimensions, materials, stitching, hardware, branding and finish are all verified. Third-party inspection adds an independent layer of assurance for larger or higher-value orders.
What payment terms apply across the journey?
The standard term is a 30% deposit to release the order and a 70% balance before shipment, quoted FOB Xiamen, with EXW, CIF and DDP available on request. Sample fees are normally settled in advance of sample work. Understanding these terms at the start of the journey, rather than at the end, allows a brand to forecast its cash position accurately across the full eleven to fourteen weeks.
What is the difference between FOB, CIF and DDP?
FOB Xiamen is the standard basis, where risk passes to the buyer at the port and the buyer arranges onward freight. CIF includes cost, insurance and freight to the destination port. DDP delivers duty paid to the buyer's address, so a corporate or retail buyer can budget a single landed cost. EXW collects from the production site. Each term shifts where responsibility and risk sit along the route.
Where does the schedule most often slip?
The journey rarely fails dramatically; it slips in small increments. An incomplete brief, extra revision rounds, a material shortage, a hardware lead time, peak-season load and freight congestion are the usual culprits. The single most effective buffer is a complete brief, because it removes the largest and most common delay. A general buffer of one to two weeks before a fixed launch date absorbs the rest.
Do I need a tech pack to start the journey?
A formal tech pack speeds up the process but is not strictly required for a first proof sample. At minimum you need a dimensioned drawing, a material and hardware list, tolerance notes and the intended use case. If you do not have a tech pack, the requirements can be structured into a workable brief. A complete pack reduces back-and-forth, which shortens the sampling stage and protects the bulk schedule.
Can changes be made after bulk production is released?
Any change after the specification freeze is treated as a formal amendment with its own impact on cost and schedule, not as a refinement. Cosmetic changes can sometimes be deferred to a later season; changes that affect structure, materials or branding require a revised sample and a re-freeze. Recording amendments formally, rather than absorbing them informally, is what keeps the programme honest.
How many revision rounds fit between the sample and bulk?
Plan for two revision rounds, one to correct everything a first sample reveals and a second to confirm the corrections. Four or more rounds usually signals a specification problem rather than a sample problem. Because each round costs roughly the length of a sample window, capping the rounds in writing before work begins protects both the budget and the schedule of the bulk order.
What documents should I hold at the end of the journey?
Keep the signed golden sample, the written specification sheet, all-angle approval photographs, the branding proof and the amendment log. Together these documents answer any later question about what was agreed and hold the production run to the standard the sample set. They cost nothing at the point of approval and prevent disputes during and after production.
Does the sample automatically become the production standard?
No. A sample is a prototype, often finished under careful conditions, while bulk is a scheduled manufacturing process judged against a quality standard. The pre-production sample, not the first proof sample, becomes the production standard, because it is made from the actual bulk materials. Sampling the standard that production can reproduce is what prevents a bulk run from failing inspection.
How can I verify the production partner handling my bulk run?
Ask for the production floor, the quality system and the sample archive. At bespoke-bags.com our SGS-verified production floor in Quanzhou (4,950 m²) runs seven lines with 149 machines and 137 staff, producing a verified capacity of 200,000 pieces per month, and bulk is inspected against AQL 2.5 under ISO 2859-1. A partner who can show all three is far better placed to carry a programme from sample to shipment without surprises.
