Kickstarter Bag Project Timeline: Sampling, Production and Delivery

A bag campaign timeline fails in a predictable way. The creator sets a delivery month by adding the production number they were quoted to the launch date, publishes it, and then discovers that the quoted number was only one of eight phases. Bulk production at 35 to 50 days is the number everyone remembers, and it is typically less than a third of the elapsed time between a closed campaign and a parcel on a backer's doorstep. The other two thirds are sampling, inspection, freight, clearance and fulfilment, and they are the parts that slip, because they depend on other people's schedules rather than on a production line you have booked.

The calendar below is built from the figures our team works to on every campaign programme: sampling at 6 to 10 working days per round (12 to 15 for a complex construction), bulk at 35 to 50 days, inspection to AQL 2.5 to ISO 2859-1, FOB Xiamen terms with T/T 30/70 payment, and 500 pcs per style and colourway as the booking unit. It is deliberately drawn with the buffers included, because a calendar without buffers is a wish rather than a plan. Where a specific number varies by product, the range is given. The sampling and prototyping pillar covers phases 2 and 3 in more detail, and the fulfilment pillar covers phases 6 and 7.

The master calendar: eight phases from brief to doorstep

The eight phases are: brief and tech pack, material sourcing, sampling, revision and pre-production sign-off, bulk production, inspection and packing, freight and clearance, and fulfilment and last-mile delivery. Two of these can run in parallel with the campaign itself and should, because they are the only phases that can be compressed without cost. Everything from sampling onwards is on the critical path, which means any delay in one pushes every subsequent milestone.

The elapsed totals, using mid-range figures: brief and tech pack 2 to 4 weeks, material sourcing 1 to 3 weeks overlapping with the tech pack, sampling 2 to 4 weeks including courier transit for two rounds, revision and pre-production sign-off 1 to 2 weeks, bulk 35 to 50 days, inspection and packing 3 to 7 days, sea freight 25 to 40 days, clearance and inland delivery 7 to 14 days, and pick-pack plus last-mile 5 to 20 days. That totals roughly 105 to 140 days of elapsed time with no slack anywhere.

Two of those phases belong before the campaign rather than after it. The tech pack and the first sample round should be complete before launch day, because the sample is the campaign photography and the credibility signal, and because the specification has to be frozen before a price can be quoted with a validity window. A creator who launches first and specifies afterwards loses 6 to 8 weeks and takes on a quoting risk, because fabric and hardware prices are held for 30 to 60 days and can move in between. This is the single largest schedule saving available, and it costs nothing but sequencing.

Phase 1: brief, tech pack and material sourcing (2 to 4 weeks)

The tech pack is the document that turns an idea into something that can be costed and made, and the time it takes is the cheapest time in the whole project. A workable pack for a bag contains a dimensioned drawing or a set of orthographic views with tolerances, a materials list with fabric denier and coating, a hardware list with brand and finish where branded parts are specified, a stitch specification including stitches per inch and seam type, a branding placement drawing, and a packing specification. Where a creator has a designer, this takes a week. Where the pack has to be built from a sketch or a reference sample, two to four weeks is realistic.

Material sourcing runs alongside the pack and it is the phase most likely to surprise. A fabric that is already in the partner's catalogue sources in days. A fabric that has to be ordered, or a colour that has to be dyed to a standard, takes 1 to 3 weeks and can take longer at certain points in the year. The two peaks that matter are the pre-Chinese-New-Year period, when production schedules compress and then stop for one to three weeks, and the late-summer backlog. A campaign planning to deliver in the first quarter of the year has to account for that shutdown, and the easiest way to do it is to build the calendar backwards from a date before the shutdown rather than after it.

The output of phase 1 should be a quotation with a stated validity window and a material reservation plan. The validity window matters because a price quoted in month one can expire before the run is booked in month four, and the reservation plan matters because a fabric that is not reserved has to be re-sourced, which is the most common avoidable delay in the whole calendar. Ask for both in writing at quotation stage. Our sourcing partner states validity on every campaign quotation precisely because that question comes up in month four, when it is expensive to discover the answer.

Phase 2: sampling at 6 to 10 working days, and why you need two rounds

Sampling is quoted per round at 6 to 10 working days for a standard construction and 12 to 15 working days for a complex one. That figure covers the pattern, the cutting and the sewing of one unit. It does not cover courier transit, which for an international parcel is typically 3 to 7 days each way, and it does not cover the review and revision cycle on the creator's side. A realistic round, door to door including review, is 2.5 to 4 weeks rather than 6 to 10 days.

Two rounds is the working assumption and three is common. The pattern is consistent: the first sample reveals proportion and fit problems that cannot be seen in a drawing, such as a strap sitting too wide, a pocket too shallow for its stated purpose, or a roll-top that does not roll cleanly. The second reveals second-tier problems, usually tension behaviour under load and hardware alignment. The third, where needed, is typically a colour or branding correction. Budgeting for three and using two is the safe position; budgeting for one and needing three is how a 35 day production window becomes a 70 day one.

Three things shorten the number of rounds, and all of them happen before the first sample is cut. The first is a dimensioned drawing rather than a reference image, because most first-round problems are dimensional. The second is a stated tolerance, because a bag specified to the millimetre with no tolerance generates arguments rather than samples. The third is a decision on hardware before sampling, because swapping a zip in round two changes the panel geometry and effectively restarts the round. Our production team reviews the pack against those three points before booking a sample slot, which is why the first-round hit rate on a properly specified bag is materially higher.

Phase 3: revision, pre-production sample and the golden sample

Between the last development sample and the start of bulk there is a step that first-time creators often skip, and skipping it is the most expensive shortcut in the calendar. The pre-production sample, sometimes called the confirmation sample or PP sample, is made on the production line with the production materials, the production patterns and the production operators. It is the last chance to catch a problem before 500 to 5,000 units are made the same way.

The reason this step matters is that a development sample is often made by a sample room, by a more experienced operator, with a slightly different machine setup from the line that will run the bulk. That difference is exactly where the problems hide: a seam that puckers at production speed but not at sample speed, a binding that feeds differently, a thread tension that behaves differently on the production machine. A PP sample costs roughly one more sample fee and 6 to 10 working days, and it is the cheapest insurance available. The golden sample is then the sealed, signed physical reference that the bulk is checked against and that the inspector compares the finished lot to.

The sign-off process should be formal even on a small run. The output of phase 3 is a signed golden sample, a written specification freeze, and a production booking with a confirmed start date. Once the golden sample is signed, any change is a change order, and a change order during bulk production is the single most damaging event in the calendar, because it can stop the line. The discipline is to treat the specification freeze as real: if something still needs changing at that point, it is better to delay the booking by a week than to change it during the run.

Phase 4: bulk production at 35 to 50 days, week by week

Bulk production runs 35 to 50 days from the confirmed start date, and the range is real rather than a hedge. The low end applies to a simple construction with catalogue materials and no custom tooling; the high end applies to a multi-panel build with custom hardware, a printed or dyed-to-match fabric, and any moulded component. Understanding what happens in each week makes the range legible and makes it possible to tell a genuine slip from a normal pace.

Weeks 1 to 2 are material preparation: fabric inspection and relaxation, dye-lot confirmation, printing or embroidery of panels if any, and hardware receipt and counting. Weeks 2 to 3 are cutting, spreading and bundling, with the marker laid to minimise waste. Weeks 3 to 6 are the sewing line, where the panels become bags, and this is the longest and most variable stage, driven by panel count and stitch count rather than by size. Weeks 5 to 7 are assembly and finishing: hardware, binding, lining, turning, and any welding. Week 7 is final inspection, cleaning, packing into polybags and cartons, and carton marking.

The most useful thing a creator can do during bulk is ask for weekly production photographs rather than waiting for a finish date. The reason is that a problem visible in week two is fixable, while the same problem discovered in week seven requires a re-run. Our programme coordinator sends a weekly status note with photographs at each stage boundary, which is partly a service and partly self-defence: it is much easier to resolve a question in week three than in week eight. The T/T 30/70 structure supports this, because the 70 percent balance is paid against shipping documents, which gives the creator a defined checkpoint before release.

Phase 5: AQL 2.5 inspection and what happens when a lot fails

Inspection to AQL 2.5 to ISO 2859-1 is the statistical gate between production and shipment. The standard defines a sample size relative to the lot size and an acceptance number for minor, major and critical defects. It is important to be clear about what it does and does not do: it establishes whether the lot is acceptable against an agreed threshold, not whether every unit is perfect. On a run of a few hundred to a few thousand units, an AQL 2.5 plan permits a small proportion of minor and major defects, and that is a deliberate commercial compromise rather than a defect.

Inspection typically adds 2 to 4 days to the calendar, plus 1 to 3 days for the report to be issued and any re-check. The three outcomes are a pass, a pass with rework, and a fail. A pass with rework is the most common result on a first run and it usually means a percentage of units have a defect that can be corrected in place, such as a loose thread, a mark, or a misaligned label. That rework adds 2 to 6 days. A fail requires either a full re-sort, which adds 5 to 12 days, or in the worst case a partial re-run.

The planning consequence is that the inspection window should be scheduled as 7 to 12 days rather than 2 to 4, with the longer figure used for a first run on a new specification. The second consequence is that a replacement stock allowance of 2 to 4 percent should be produced or held, because the defects that pass inspection at the threshold will surface as warranty claims over the following months. The relationship between the inspection result and the packing specification is covered in more depth in the QA and QC pillar, including what to put in an inspection checklist for a bag specifically.

Phase 6: freight, clearance and inland delivery (32 to 54 days by sea)

The freight leg is where calendars most often slip, because it is the phase with the most external dependencies and the least control. Sea freight typically runs 25 to 40 days port to port depending on the route and whether the sailing is direct, plus 3 to 7 days for export handling and loading at origin, plus 4 to 10 days for import clearance, plus 3 to 7 days for inland delivery to the fulfilment warehouse. The realistic door-to-door planning figure is 35 to 60 days, and it should be scheduled as such rather than as the port-to-port headline.

Air freight runs 5 to 10 days door to door and costs roughly 3 to 6 times the sea rate per kilo. The decision is rarely all-or-nothing. The structure that works for most campaigns is sea for 90 to 95 percent of the units, with 5 to 10 percent flown ahead as a buffer for the earliest delivery wave, for replacements, and for the press and influencer units that need to land early. That air portion typically adds 3 to 8 percent to the total freight bill and removes most of the schedule risk on the first wave.

Clearance is the sub-phase most likely to produce an unplanned delay, and the causes are almost always documentary rather than physical. A shipment needs a commercial invoice, a packing list, a bill of lading or air waybill, and in most destinations a country of origin declaration. Where the destination is a VAT market, the importer of record must be identified and registered before the goods arrive. A shipment arriving without one of those documents can sit at the port accruing storage charges at a daily rate, and that is the situation that turns a 40 day freight leg into a 60 day one. The tax and customs guide sets out the documentation pack in detail.

Phase 7: pick, pack and last-mile fulfilment (5 to 20 days)

Once stock lands at the fulfilment warehouse, three things have to happen before a backer receives anything. Receiving and counting takes 1 to 3 days, longer if cartons arrive damaged or the counts do not match the packing list. Pick and pack depends on volume and complexity: a single-SKU run of 1,000 units can be picked in 2 to 4 days, while a run with three colourways, two sizes and a personalisation option can take 8 to 15 days because each parcel is a unique pick. Last-mile delivery then varies enormously by destination, from 1 to 3 days domestically to 7 to 21 days for an international economy service.

The complexity variable is the one to plan around. A campaign with a single product and no variants is a straightforward bulk ship, and a warehouse will process it quickly. A campaign with variants and add-ons is a pick-per-order operation, and the throughput is lower and the error rate higher. The mitigation is to give the warehouse a clean export file from the pledge manager with one line per backer, the variant code, the add-on codes and the validated address, and to agree a daily throughput target in writing before the stock arrives.

The second planning variable is the wave structure. Shipping in one wave is simplest and cheapest per unit, because the warehouse sets up once. Shipping in regional waves, meaning UK and EU first, then North America, then rest of world, costs slightly more per unit but improves the backer experience in the markets that would otherwise wait longest for the same goods. The deciding factor is usually freight rather than fulfilment: if the sea shipment lands in one port, splitting into regional waves means an onward leg, whereas shipping directly to two regional warehouses from origin removes a step and usually a week.

Building the public delivery date backwards from this calendar

The method is to start from the desired delivery month and work backwards, phase by phase, using the upper end of each range rather than the lower one. The reason for using the upper figure is asymmetric cost: if you plan to the low end and the project runs to the high end, you have missed a public promise, which damages the campaign and generates refund requests. If you plan to the high end and the project runs to the low end, you have delivered early, which generates goodwill at no cost.

Worked example for a campaign aiming to deliver in a given month. Take the first of that month as the target. Subtract 10 to 20 days for fulfilment and last mile. Subtract 35 to 60 days for freight, clearance and inland delivery. Subtract 7 to 12 days for inspection, rework and packing. Subtract 50 days for bulk production, using the upper figure. Subtract 1 to 2 weeks for PP sample and sign-off. Subtract 4 to 6 weeks for sampling rounds including transit. That puts the production start roughly 115 to 155 days before the delivery month begins, and since production cannot start until the campaign closes and the survey is in, the campaign must close at least that far ahead of the stated delivery month.

Which produces the uncomfortable conclusion that most first-time creators resist: the delivery month is largely determined by the launch date, and it is further away than it feels. A campaign launching in early spring with a specification still to be settled is realistically delivering in late autumn. The two ways to compress that are to complete the specification and sampling before launch, which removes 6 to 10 weeks, and to accept a single colourway, which removes the split-confirmation step and typically a week of sampling. Both are decisions made before the campaign page is published rather than after it funds.

Where the calendar slips and how much buffer each phase needs

Not all buffers are equal, because the phases have different variance. Sampling has high variance and needs the largest proportional buffer, because a round either works or it does not, and a failed round costs the full 6 to 10 working days again. Freight has high variance because sailings, weather and clearance are outside anyone's control. Bulk production has moderate variance, because a booked line runs to a plan, and the main risk is a change order rather than a slow line. Pick and pack has low variance once the export file is clean.

The practical allocation, on a 140 day calendar, is roughly: 2 weeks on sampling, 1 week on PP and sign-off, 5 days on bulk, 5 days on inspection and rework, 10 days on freight and clearance, and 5 days on fulfilment, for a total of about 6 weeks of buffer. That sounds generous and it is not: it is roughly 25 percent of the elapsed time, and it is the difference between a promise that holds and one that does not. The buffer should never be published, because a published buffer becomes the new deadline in the backers' minds.

There is one exception to the buffer-everything rule, and it is worth stating. Do not buffer the specification. A tendency to keep the specification open a little longer in the hope of improving it is the most expensive form of procrastination in this process, because every week the specification stays open is a week the material is not reserved and a week the sample slot is not booked. The right sequence is to freeze the specification at a good-enough point, book everything, and improve the product on the second run, where the patterns, the materials and the line are all already proven.

Three compressed scenarios and what they cost

Sometimes the calendar has to be compressed, and it is useful to know what each compression actually buys. Scenario one is air freight instead of sea. This saves roughly 25 to 45 days and costs 3 to 6 times the sea rate per kilo. On a 500 pcs run with a packed weight around 0.9 kg per unit, that is a substantial five-figure difference at the upper end, which is why the usual answer is to fly 5 to 10 percent and ship the rest.

Scenario two is to sample and specify before launch. This saves 6 to 10 weeks of elapsed time and costs almost nothing, because the sampling fee would have been paid anyway, and the only additional cost is that the specification is frozen earlier than it otherwise would be. It is unambiguously the best compression available and it is the one most first-time creators decline, usually because they want the campaign to fund the sampling. The counter-argument is that a campaign with a real sample converts measurably better than one without, which means the sampling cost is usually recovered in the funding.

Scenario three is to reduce to a single colourway and stock hardware. This saves roughly 2 to 4 weeks: one fewer dye lot to confirm, one fewer sample round for colour approval, no tooling lead time on custom pulls or badges, and no colourway split to wait for at survey close. The cost is a less varied reward offering. For a first campaign where the schedule matters more than the choice, this is the right trade. Our team sees it outperform the alternative regularly, because a campaign that delivers on time with one colourway builds more trust than one that delivers late with three.
