Why Evidence Packs Win Claims
Bulk claims fail for one predictable reason: the issue is described verbally, but the supplier cannot verify it quickly. A strong evidence pack makes your claim auditable: anyone reviewing it can reproduce counts, confirm batch identifiers, and see the defect clearly—without guessing what happened between receiving and storage.
What “good” looks like
One folder with counts, photos, defect codes, and lot records that tells a complete story in under 3 minutes.
What causes delays
Missing carton labels, unclear photos, no sample retention, no “how many affected” number, or no timeline.
What to standardize
Claim format, defect codes, photo checklist, sampling plan, and a simple response SLA for every batch.
Claim Triage in 10 Minutes
Before collecting everything, run a quick triage so you don’t waste time building the wrong case. Your goal is to answer four questions fast:
| Triage question | What to capture | Why it matters |
|---|---|---|
| Is this count, damage, cosmetic, functional, or scanability? | Pick one primary defect category | Suppliers route different teams based on defect type |
| How many units are affected? | Exact number or sampling-based estimate | Claims need scope, not anecdotes |
| Which batch identifiers apply? | PO, carton label photos, any lot/date codes | Batch linkage is the backbone of resolution |
| Can we isolate samples? | Yes/no, quantity, storage location | Sample retention prevents disputes later |
The Evidence Pack Checklist
Use the checklist below as the minimum set of artifacts for a complete claim. You can think of it as “what a third-party auditor would need to verify the issue without visiting your site.”
| Evidence item | Required | How to capture | Common mistakes |
|---|---|---|---|
| PO and shipment identifiers | Yes | PO, invoice/packing list, receiving date/time, warehouse location | Only listing a PO number with no receiving timestamp |
| Carton label photos | Yes | Clear photo of each unique carton label and any lot/date codes | Blurry labels or cropped codes |
| Counts and reconciliation | Yes | Expected vs received by carton and totals; log exceptions | “Short a few” with no counted proof |
| Defect scope estimate | Yes | 100% count or sampling-based estimate with method stated | No method described (“about 20%”) |
| Defect photos and/or video | Yes | Photo set that shows context + close-up + scale | Only close-ups with no context |
| Sample retention | Strongly recommended | Set aside labeled samples from affected cartons | Mixing samples without carton mapping |
| Scanability evidence (if applicable) | When needed | Scanner screenshot/photos and grading notes | Only “QR does not work” with no reproducible proof |
| Handling and storage notes | When disputed | Short record of storage conditions and handling chain-of-custody | No chain-of-custody when damage is disputed |

Defect Codes That Reduce Back and Forth
Defect codes are a simple way to prevent long email threads. They force you to specify what failed, where it was observed, and what proof exists. Pick a simple set that your entire team uses.
| Code | Category | Definition | Evidence to include |
|---|---|---|---|
| C01 | Count | Shortage or overage vs packing list | Counts by carton, label photos, reconciliation sheet |
| D01 | Damage | Transit damage visible on cartons or inner packs | Wide context photos, close-ups, carton mapping, stack photos |
| D02 | Cosmetic | Scratches, scuffs, rub marks, print/fade issues | Close-up + context, grading examples, “acceptable vs reject” notes |
| F01 | Functional | Hardware does not activate or is inconsistent | Test notes, affected count, sample retention, batch identifiers |
| S01 | Scanability | Barcode/QR scan failures or low-quality prints | Scanner proof, label photos, verification notes |
| P01 | Packing | Wrong inserts, missing components, incorrect pack-out | Unboxing video, BOM/expected contents list, carton mapping |
Sampling and How to Avoid Anecdote Claims
When a full 100% inspection is impractical, sampling turns “we saw a few defects” into a quantified claim with a method. If you use a recognized sampling standard and document how you applied it, resolution is typically faster and less subjective.
What to state
Lot size, sample size, how samples were selected, and the observed defect rate.
What to avoid
Cherry-picked samples without explaining selection, or mixing cartons with unknown mapping.
Best practice
Sample across multiple cartons and record carton IDs so the supplier can trace the same path.
For a widely used entry point into acceptance sampling, many quality teams reference ANSI/ASQ Z1.4 frameworks when designing inspection plans and documenting the method.
Photo and Video Standards
The fastest claim is the one where the supplier can see the defect instantly. Use a consistent photo set:
Photo set A context
One wide shot of the carton stack and the affected carton ID.
Photo set B label
Clear carton label photo showing identifiers and any lot or date codes.
Photo set C defect close up
Close-up with the defect centered and in focus; include a simple scale reference if helpful.
Photo set D proof of scope
Grid photos of multiple affected units or a short video sweep across sampled units.
Timelines and SLAs
Delays happen when nobody agrees on a response window. Add a simple SLA to every claim: initial acknowledgement, evidence review, and proposed resolution options.
| Stage | Target window | Your responsibility | Supplier responsibility |
|---|---|---|---|
| Acknowledge claim | 1 business day | Send evidence pack link + summary table | Confirm receipt and case owner |
| Evidence review | 2 to 4 business days | Provide samples if requested and available | Validate identifiers and defect classification |
| Resolution proposal | 5 to 10 business days | Confirm preferred remedy and timeline | Offer replacement credit or rework plan |
When damage is disputed, having a packaging stress reference can help frame discussions. Teams often point to ISTA 3A-style parcel shipment stresses (drop, vibration, compression) as a baseline for what packaging is expected to survive.

FAQ
What is the minimum evidence pack for a bulk claim
At minimum include PO identifiers, carton label photos, a counted scope number, clear defect photos with context, and a folder that maps affected units to carton IDs. If the issue is disputed, sample retention is strongly recommended.
How many samples should we retain
Retain enough to re-show the defect reliably and represent multiple cartons. Label each retained unit with carton ID and the defect code so it remains traceable.
How do we avoid claims that get stuck in email threads
Use defect codes, keep one evidence folder per claim, state the sampling method and scope, and set a clear acknowledgement and update timeline. Short factual summaries reduce back-and-forth.
