OEM and ODM are often used as broad labels, but the practical question is simple: who provides the starting design, and who is responsible for developing each part of the specification? A successful sofa project defines those responsibilities before drawings, samples and prices begin to change.
In an OEM project, the buyer typically supplies a more developed design or specification and asks the manufacturer to produce against it. In an ODM project, the buyer may begin with a market position, visual direction or functional goal and use more of the manufacturer’s development input. Real projects can sit between the two. The contract, not the label, should define ownership, confidentiality, approved scope and responsibility.
Stage 1: Qualification and feasibility
Begin with the business case. Share the intended market, product tier, expected quantity, target launch window, destination and any non-negotiable requirements. The manufacturer can then identify missing information, likely development steps and obvious feasibility concerns.
At this stage, avoid presenting a target price without explaining what it must include. Clarify whether the target covers development, packaging, testing, freight or other services. If a requirement depends on a particular material, process or regulation, flag it before design work advances.
Approval gate: both parties agree on the project scope, information needed for quotation, confidentiality terms where applicable and the person authorized to approve decisions.
Stage 2: Design definition
The design package should convert inspiration into identifiable features. It may contain overall views, target dimensions, intended seat count, key curves, arm and back language, cushion arrangement, seam positions, visible finish zones and matching pieces. Reference images should be annotated so the team knows what is being referenced: proportion, color, detail or general mood.
Avoid copying protected branding or assuming that a photographed construction can be reproduced from appearance alone. A new product should be reviewed for its own identity, manufacturability and market obligations. If design ownership is important, address intellectual-property review with qualified advisers in the relevant markets.
Approval gate: a dated design direction or drawing set is accepted as the basis for development.
Stage 3: Specification and quotation
The product specification turns visible design into order language. It should identify the upholstery selection, color reference, stitch direction, cushion concept, decorative finishes, visible quality criteria, labeling, packing and required documentation. Construction and performance requirements should be described only where verified and agreed; they should not be guessed from a reference product.
The quotation should refer to the same specification revision. Development fees, sample fees, tooling where relevant, order price, included pieces, payment terms, packing basis and exclusions should be itemized. If several options are quoted, give each one a separate code so later approvals cannot be confused.
Approval gate: the buyer selects a priced specification for sampling, with open items listed explicitly.
Stage 4: Materials and finish alignment
Screens and photographs are unreliable for final color approval. Use coded physical swatches or formally controlled samples whenever possible. Review upholstery beside decorative finishes and adjacent pieces under suitable light. Note acceptable natural variation and identify any surfaces where matching is especially critical.
For buyer-nominated materials, confirm supply responsibility, required quantity allowance, inspection procedure, replacement responsibility and what happens when deliveries are late or inconsistent. For manufacturer-proposed alternatives, record the exact sample approved rather than accepting a generic description such as “similar beige.”
Approval gate: the material and finish board is signed, dated or otherwise formally recorded.
Stage 5: Prototype or pre-production sample
The sample is used to resolve the gap between drawings and physical experience. Review proportion, visual balance, seat and back direction, seams, piping, alignment, surface quality, loose parts and access for delivery. Photograph every side and record each requested correction in one list.
A correction is not complete merely because it has been discussed. The revised sample, drawing or written specification must show how the issue was closed. If the buyer approves a sample with known exceptions, those exceptions should be listed so they do not become accidental standards.
Approval gate: a clearly identified sample and its associated documents are approved as the production reference.
Stage 6: Pilot confirmation and production control
For complex or high-value programs, a first-unit or small pilot review can confirm that approved decisions have transferred into production. Check identity, color references, critical visible details, assembly, labels and packing. Define inspection frequency and who may authorize a deviation.
Changes after production authorization should follow a written change process. The request must state the revision, affected quantity, price impact, schedule impact and disposition of work already completed. Uncontrolled late changes are a common source of mixed versions and delivery delay.
Approval gate: the authorized production revision is frozen, except for documented changes.
Stage 7: Final inspection, packing and handover
Final review should use the approved specification and reference, not memory. Verify quantities, variants, visible workmanship, required checks, labels, accessories, packing marks and shipment documents. Record exceptions and their resolution before loading.
The handover package may include the final product list, approved revisions, packing list, inspection record, care information where supplied and agreed shipping documents. The actual package depends on the contract and destination requirements.
What buyers should prepare for an efficient first discussion
Send a concise brief with your market, product direction, pieces, quantity, destination, target timing, reference images and known mandatory requirements. Mark unknown items honestly. A well-defined unknown can be developed; a hidden assumption usually becomes a late change.
HANRAN HOME can review submitted concepts and reference products as part of an initial project conversation. Feasibility, development responsibilities, sample route, price and schedule are confirmed project by project in writing.
