Same Drawing, Two Quotes: How to Read a Bike Bag Quotation

Two factories can quote one drawing far apart and both be honest. The six cost lines inside every bike bag quote - and five questions that expose the gaps.

Short answer: a quote is not a price; it is a bundle of six cost lines. The lines are material, cutting yield, labor steps, tooling and sampling, packaging, and freight. Two factories can quote the same drawing far apart and both be honest, because the lines differ. Compare the lines, not the bottom line. Send us your drawing and we will quote line by line.
You send one drawing to three factories. The quotes come back with different totals - sometimes far apart. None of the factories is necessarily lying.
A quote is a bundle of six cost lines, and each line moves with a different decision: the fabric spec, the pattern nesting, the number of stitching steps, the tooling policy, the packaging standard, the shipping terms. Read the lines, and the gap stops being mysterious.
This guide is for buyers comparing quotes for a custom bike bag, cover or cushion. It shows what belongs in each line, why honest quotes differ, and the five questions that expose a thin quote before it becomes a thin product.
Key takeaways
• A quote has six lines: material, cutting yield, labor steps, tooling and sampling, packaging, and freight. Ask for all six; a single unit price hides which one moved.
• The same “600D” is not the same material. Denier, coating type and coating weight, and finish all change cost - ask for the fabric's full spec, not the marketing name.
• Cutting yield is invisible but real. The same pattern nested differently can consume measurably different meters per bag - an illustrative 1.1 m vs 1.3 m example is worked below.
• Tooling and sampling should be one-time costs. Ask whether a reorder pays them again; a quote that resets tooling every order is not the same offer.
• Freight and duty sit outside the factory price. Compare ex-works vs landed; a lower unit price with worse terms can lose on delivered cost.
How we verified this
This is a quotation-literacy guide, not a price list. The six-line structure comes from how our own quotations are built; the arithmetic example is labelled as arithmetic, not a quotation. Our published operating facts (MOQ 30 for ready styles, 300 for custom development; sampling 7-12 days; production 45-55 days after approval and deposit) are stated on our product pages. No invented supplier prices.
The six lines inside every quote
• Material. Fabric, foam, lining, webbing, buckles, zippers - each with a spec. Ask for denier, coating type and weight, hardware brand and model. “Waterproof fabric” is not a spec.
• Cutting yield. How many meters the pattern consumes per bag, including waste. Ask for the assumed yield; two factories can differ here before any labor happens.
• Labor steps. Stitching operations, bartacks, seam sealing, hardware setting, final QC. Ask how many operations the price includes - and which ones are skipped to hit a target.
• Tooling and sampling. Patterns, cutting dies, screens or print files, and the sample itself. Ask whether it is one-time, and whether the sample fee credits against production.
• Packaging. Polybag, carton, label, insert, pallet. Ask what is included; packaging differences are small per unit and large per container.
• Freight and duty. Usually outside the factory price. Ask for the Incoterm: ex-works, FOB or delivered - and who books the freight.

What it means for importers: require a line-item quote for any order you will repeat. You cannot manage a cost you cannot see.
Why two honest quotes differ
• Fabric spec. A “600D” can carry different coating weight, different backing and a different finish. Material cost moves before anything is sewn.
• Yield assumptions. Pattern nesting, fabric width and defect allowance change meters per bag. A tighter nest is real savings - and a cheap quote may simply assume a tighter nest than the fabric allows.
• Hardware brand. A named buckle and zipper cost more than an unbranded equivalent. Ask for brand and model, then compare like with like.
• MOQ tier. Ready styles run from 30 pieces; full custom development starts at 300. A quote at a different tier is a different product scope, not a discount.
• QC intensity. Full inspection versus spot checks is a labor line. Ask what percentage is inspected and against which checklist.
What it means for importers: when totals differ, find the line that moved before you negotiate. Most “expensive” quotes are buying something the cheap one is not.
The arithmetic of yield (illustrative)
Take 1,000 bags and a fabric at 10 per meter - both illustrative, not a quotation.
• Factory A nests the pattern at 1.1 m per bag: 1,100 m, or 11,000 in fabric.
• Factory B nests at 1.3 m per bag: 1,300 m, or 13,000 in fabric.
• Difference: 200 m, 2,000 total, or 2 per bag - before a single stitch.
Now push the same logic to 300 pieces: the gap shrinks to 600. Push volume up and the yield line becomes the largest negotiable item in the quote - which is why factories ask for quantities before quoting.
(Figure 2: Yield arithmetic - the same pattern, two nests, 1,000 bags. Chart pending upload; data listed above.)
What it means for importers: ask every supplier for the yield they assumed. If they cannot state it, they cannot defend the material line.
Five questions that expose a thin quote
• “Can you show the six lines?” A quote that refuses a breakdown is pricing a feeling, not a product.
• “What is the fabric's full spec?” Denier, coating, weight, backing. If the answer is “same as your sample”, the quote is not comparable.
• “What yield did you assume?” This is where honest differences and hidden shortcuts both live.
• “Is tooling one-time, and does sampling credit?” Reorders should reuse approved patterns and samples - not pay again.
• “What Incoterm is this?” Ex-works and delivered are different offers. Compare landed cost, not unit price.
What it means for importers: these five questions take one email. The answers separate a quote you can manage from a number you will argue about later.
Limitations
• This guide describes quote structure, not our prices; every project is quoted from its drawing and materials.
• The yield example is illustrative arithmetic, not a quotation or a promise.
• Packaging and freight vary by market; confirm Incoterms before comparing.
• Tier facts (30/300) and timelines (7-12 and 45-55 days) are our published operating facts.
FAQ
Why do two factories quote the same drawing so differently?
Because quotes are built line by line, and lines move independently: fabric spec, yield, hardware brand, QC intensity, tooling policy, freight terms. A gap usually maps to one or two lines - find them before negotiating.
Is the cheapest quote always the risky one?
No. The cheapest quote can be honest when it assumes a simpler spec or a larger volume. The risk is a cheap quote with no breakdown - you cannot see what was removed.
What should a line-item quote include?
Material, yield, labor operations, tooling and sampling, packaging, freight, and the Incoterm. It should also state the MOQ tier and the inspection level the price assumes.
How does yield affect my unit price?
Yield is meters consumed per bag, including waste. A pattern that consumes more fabric per bag raises the material line directly - and the effect grows with order size.
Should I compare ex-works or delivered prices?
Compare delivered (landed) cost: ex-works price plus freight, insurance and duty. A lower ex-works number can lose once the shipping terms are included.
