Step 1: Define the particular purpose
Write a precise description of what the goods needed to accomplish.
Include:
- The intended application
- The machine, vehicle, system, material, or software involved
- Required capacity or performance

Step 2: Show what the seller knew
Gather evidence showing that the seller had reason to know the purpose before the purchase.

- Sales-chat records
- Specifications
- Drawings

Step 3: Document the request for seller judgment
Preserve evidence that the buyer asked the seller to select, recommend, or confirm suitable goods.
Statements may include:
- Please recommend the correct product.
- Which model will meet these requirements?
- Will this product work with the identified system?
- Please confirm that this material is suitable.
Step 4: Preserve the seller's recommendation
Save the exact product recommendation and any limitations or assumptions.
Evidence may include:
- Email recommendation
- Quotation
- Product-selection worksheet
- Chat transcript
- Compatibility confirmation
- Invoice notes
- Automated selector results
Step 5: Explain buyer reliance
State how the seller's recommendation affected the purchase.
I purchased the recommended product because the seller reviewed my stated requirements and represented that the product was suitable for that purpose.
Note whether the buyer changed an earlier selection, accepted an alternative, or proceeded only after seller confirmation.
Step 6: Gather the sales documents
Collect:
- Receipt
- Invoice
- Order confirmation
- Product listing

Step 7: Prove the goods were unsuitable

- Expert findings
Step 8: Preserve the product and components
Keep the goods available for inspection when safe and practical.
Preserve:
- The complete product
- Removed components
- Packaging and labels
- Serial and model numbers
- Samples or residues where appropriate
- Installation photographs
Step 9: Separate other possible causes
Determine whether the problem may involve:
- Incorrect installation
- Buyer misuse
- Changed operating conditions
- Incomplete buyer information
- Maintenance failure
- External system problems
- A manufacturing defect unrelated to selection
Step 10: Review disclaimer language
Check whether the seller attempted to exclude or modify the implied fitness warranty.
Review:
- Whether the exclusion was written
- Whether it was conspicuous
- When it was disclosed
- Whether as-is language was used
- State-law restrictions
- Written warranties and service contracts
- Specific suitability promises
Step 11: Send written notice
Notify the seller promptly after discovering the unsuitability.
Include:
- Buyer name and contact information
- Purchase date and order number
- Product identification
- Particular purpose
- What the seller knew
- The seller recommendation
- How the goods were unsuitable
- Supporting evidence
- The requested response
Keep proof of delivery.
