Supplier comparison
Use this matrix when you are comparing 2-5 sauna suppliers after initial due diligence but before sample order, production deposit, quote approval, or repeat-order allocation. It keeps supplier details, quote assumptions, and service risk visible side by side.
A supplier comparison matrix is not a price sheet. It shows whether each supplier can prove the scope behind the price.
Where the Matrix Fits
Supplier Comparison Matrix
| Decision field | Supplier A | Supplier B | Supplier C | Buyer decision rule |
|---|---|---|---|---|
| Supplier identity | Named export owner, sauna focus, company proof. | Contact only, unclear role. | Trading claim plus partial proof. | Do not shortlist a supplier without accountable owner and sauna-specific role proof. |
| Factory verification | Workshop, material, production, QC, packing, finished sample photos. | Factory photos but no sauna line. | Third-party audit pending. | Factory photos must match the model family, material, and order size being quoted. |
| Product fit | Model codes, dimensions, wood, heater, voltage, glass, accessories clear. | Broad catalog only. | Good model fit but unclear accessories. | Compare only written scope, not visual similarity or catalog promises. |
| Compliance support | Certificate scope, labels, manuals, voltage, importer duties clarified. | General compliance claim. | Partial documents. | Supplier must separate factory documents from buyer/importer responsibility. |
| RFQ quality | Answers assumptions and asks clarifying questions. | Pushes price first. | Good technical answers, slow timing. | Strong suppliers reduce ambiguity before quoting. |
| Quote transparency | MOQ, incoterm, payment, lead time, inclusions, packing, warranty clear. | Low price but exclusions unclear. | Higher price but complete scope. | Shortlist the quote with fewer hidden assumptions, not just the lowest unit price. |
| QC and packing | Inspection steps, issue closure, labels, packing photos, loading proof. | No pre-shipment photo plan. | QC available on request. | Balance payment should not happen without inspection and packing evidence. |
| After-sales | Warranty limits, claim photos, spare parts, service owner, escalation path. | Warranty sentence only. | Spare parts unclear. | After-sales route must be operational, not only written as a warranty promise. |
Model-normalized supplier comparison
Compare suppliers against the same sauna model family
A supplier comparison is only fair when each factory is asked to quote the same model assumptions. Use this matrix to normalize product scope, evidence, packing, and after-sales questions before comparing price or choosing a shortlist.
| Model family | Reference product | Normalize before comparing | Evidence required | Supplier comparison risk |
|---|---|---|---|---|
| Barrel sauna | CSA-01 red cedar barrel sauna | Length, diameter, wood species, roof finish, heater option, hoop material, crate size. | Product photos, wood/hoop details, roof sample, heater confirmation, packing photo. | Lowest price may hide thinner panels, weaker roof material, or different heater assumptions. |
| Outdoor cube sauna | CSA-02 outdoor cube sauna | Footprint, glass side, door swing, voltage, cladding, base frame, roof/waterproofing detail. | Wall build-up, glass seal, base frame, exterior finish, loading and protection photos. | Quotes look similar but site delivery, weather resistance, and glass layout may be different. |
| Commercial sauna | CSA-05 commercial cedar sauna | Room size, peak users, heater power, controller, compliance target, handover file scope. | Submittal drawing, heater certificate, bench load note, installation manual, maintenance path. | Supplier may quote a room but not the project evidence needed by hotels, gyms, or spas. |
| Wood-fired outdoor sauna | Wood-fired outdoor sauna room | Stove kit, chimney route, heat shield, outdoor coating, spare parts, destination warnings. | Stove/chimney photos, fire-clearance note, coating sample, spare-part list, crate photo. | Price comparison is unsafe if fire, chimney, and destination restrictions are not aligned. |
Shortlist Rules
Do not compare price before scope
Normalize heater, voltage, wood, glass, accessories, packing, labels, manuals, warranty, and incoterm before choosing the lower quote.
Do not accept proof that is unrelated
Factory photos should match sauna product family, production scale, material, QC stage, packing plan, and destination-market assumptions.
Do not hide unresolved gaps
Every blank cell should become a due-diligence question, RFQ field, sample requirement, inspection item, or after-sales responsibility.

Due Diligence Checklist
Run due diligence first so weak suppliers do not enter the final shortlist.
Factory photos
Factory Verification
Check whether factory photos supports claimed sauna manufacturing capability.
Evidence routing
Factory Details
Route each comparison gap to RFQ, audit, quote, QC, packing, or after-sales details.

Supplier Trust Center
Review CSauna proof signals before treating supplier claims as evidence.
Quote comparison
Quote Scorecard
Compare quotes only after supplier scope and included assumptions are aligned.

Compare warranty route, claim photos, spare parts, and service owner.
Next step
Convert Weak Cells Into Buyer Actions
If one supplier has missing proof, do not guess. Route the gap to due diligence, factory verification, quote comparison, RFQ questions, QC inspection, packing proof, or after-sales evidence before choosing the shortlist.
Factory Photos for Supplier Comparison
Compare sauna suppliers against visible proof, not only price lists: factory identity, workshop process, wood material, assembly, inspection, and finished samples.
