How to Prepare a Custom Bag RFQ That a Factory Can Actually Quote

A useful RFQ does not need to be a finished technical pack, but it does need to explain the job the bag must do. When the first message only says “send your best price,” the supplier has to guess at materials, dimensions, performance and packing. Those guesses make quotations difficult to compare and usually create changes later.

Start with the use case

Describe who will carry the bag, what it holds, how long it is used and the environment it faces. A fishing cooler exposed to salt spray has a different risk profile from a meal-kit tote that must be cleaned and circulated every day.

Define the starting specification

  • Product type and reference photos or links
  • Dimensions, capacity and target load
  • Preferred outer material, lining and insulation
  • Closure, seam and waterproof expectations
  • Pockets, straps, hardware and branding
  • Packaging and labeling requirements

Add the commercial boundaries

Include target market, estimated quantity, launch timing and any target cost position. These are not promises; they help the supplier choose a realistic construction and production route.

State how approval will work

List the tests, measurements and appearance points that matter most. Ask the supplier to identify missing decisions before sampling. The goal of the first review is not a perfect quotation—it is a shared understanding of what still needs to be confirmed.

Turn the first enquiry into a decision-ready brief

Separate fixed requirements from preferences. A delivery company may have a fixed vehicle opening but still be flexible about pocket placement. An outdoor brand may require a particular retail footprint while allowing the factory to propose the lining. Mark each item as required, preferred or open for recommendation. This gives engineering room to solve the right problem without quietly changing your priorities.

A useful illustrative brief would say: develop a soft cooler for a day-trip collection, carrying the listed containers and coolant, with a removable shoulder strap and space for a retail label. Attach container dimensions, a loading photo and a sketch of the desired opening. This is more actionable than a nominal litre figure alone. Do not copy another brand’s capacity claim without checking what was packed inside.

Ask for the quotation assumptions in writing. A lower unit price may reflect a different fabric, omitted packaging or a simpler closure, rather than a more efficient offer. Keep optional upgrades on separate lines so the base construction remains comparable. Sample charges, development work and delivery terms should be identified separately from production pricing.

What a complete RFQ should let the factory decide

Review area What to define Decision or evidence
Loading reference Item sizes, loading photo and intended carry load Usable dimensions and reinforcement needs
Material preferences Fabric reference, finish and cleaning expectations Available construction options and trade-offs
Brand presentation Artwork, placement sketch and retail pack format Decoration method and packing feasibility
Approval milestones Who signs off dimensions, appearance and testing Which decisions must be closed before production

What if the technical pack is not ready?

Send the known requirements and label the gaps. Request a drawing or specification review before paying for a final sample. Record who will resolve each open point; a provisional quotation should not be treated as approval of an unspecified feature.
