For ecommerce sellers on Amazon, Shopify, eBay, Etsy and global marketplaces. Updated May 2026.
Most merchants lose winnable disputes not because they have no evidence — but because they submit the wrong evidence for the reason code, submit it in the wrong order, or submit evidence that answers a different question than the bank is asking.
Banks and card networks do not evaluate all evidence equally. They have an implicit hierarchy, and submitting lower-tier evidence when higher-tier evidence exists — or is possible to create — is the most common cause of preventable dispute losses.
This guide maps the complete hierarchy of ecommerce dispute evidence ranked by actual effectiveness, explains what each level proves and does not prove, and identifies the evidence gap that most merchants have and do not know about.
The Five Tiers of Ecommerce Dispute Evidence
Tier 1: Independently Verifiable Fulfillment Proof (Highest Impact)
Order-linked packing video is the highest-tier evidence in product disputes. A recording of the specific order being packed, showing the product and its condition, linked to the Order ID at the time of recording, timestamped. It is evaluated as Tier 1 because it does not require the bank to accept either party's account — it is independently verifiable. The video shows what was in the box for that specific order. This fact can be verified without relying on anyone's written account.
When does it win: "Item not as described," "wrong item received," "item arrived damaged" claims where the merchant packed the correct product in good condition. The video shows this independently.
When it does not apply: "Item not received" claims where delivery, not contents, is the dispute. Tier 2 is primary for these.
Return receipt opening video is Tier 1 evidence for the return side. Shows what arrived in the return parcel when opened on camera. Combined with Tier 1 dispatch video, creates the complete before-and-after evidence chain for swap fraud and empty box returns.
Tier 2: Delivery Confirmation (High Impact for Non-Delivery Claims)
Carrier delivery confirmation showing the parcel was delivered to the buyer's address. Tracking records from a recognized carrier showing all transit events and delivery scan. This is the primary evidence for "item not received" disputes.
Signature confirmation is required by Visa and Mastercard for orders above $750 to qualify for seller protection. Below this threshold, delivery confirmation without signature is sufficient for most networks.
GPS delivery photo where available from the carrier. Specifically documents the physical address and delivery point.
What Tier 2 proves: the parcel arrived at the address on the order. It does not prove the contents.
When Tier 2 is insufficient: "Item not received" disputes that escalate to "received but empty" or "received but wrong item." At this point, the dispute has shifted from delivery to contents, and Tier 1 evidence is required.

Tier 3: Transaction and Customer History
Prior undisputed transactions from the same cardholder within 120 days, with matching device or IP data. Relevant to Visa CE3.0 submissions for reason code 10.4 fraud disputes. Shows a pattern of legitimate purchases that contradicts an "unauthorised transaction" claim.
Device and IP matching. The IP address and device fingerprint from the transaction match the billing address on record. Relevant for fraud-code disputes.
Communication records. Emails, chat logs, or support tickets showing the customer acknowledged the order, confirmed receipt, requested return authorisation, or expressed satisfaction before the dispute. Directly contradicts "never received" or "never authorised" claims when the customer communicated about the delivered order.
What Tier 3 proves: the transaction pattern and customer engagement context. It does not independently verify product contents.

Tier 4: Supplementary Product Documentation
Product condition photos at packing with the Order ID visible in the frame. Useful when no packing video exists. Less effective than video because photos are easier to dispute — they cannot show the complete sequence from product pick to box sealing.
Listing accuracy documentation. The original product listing showing the description and images that matched the shipped item. Relevant for "not as described" disputes where the listing is at issue.
Weight records. Return parcel weight at receipt compared to original product weight. Physical evidence of discrepancy in swap fraud and empty box cases. Strongest as corroborating evidence alongside opening video.
Tier 5: Written Accounts and Standard Business Records (Lowest Impact)
Written rebuttal letters describing what was packed. The merchant's account of events. Not independently verifiable. Most useful as the narrative framework referencing higher-tier evidence rather than as standalone proof.
Order management records. Confirmation the order was placed, assigned, and marked as fulfilled. Proves the order was processed, not what was inside.
Shipping weight at dispatch. The weight recorded by the carrier at collection. Useful as supporting data for "wrong item" or "empty box" disputes when combined with return weight, but not independently verifiable as proof of specific contents.
Why Most Merchants Default to Tier 4 and 5
The reason most merchants lose disputes is not that Tier 1 and 2 evidence is inaccessible — it is that Tier 1 evidence (order-linked packing video) requires infrastructure that most merchants do not have.
Building Tier 1 evidence at scale requires automated recording triggered by shipping label scan, automatic linking of recordings to Order IDs in real time, indexed cloud storage retrievable by Order ID, and sub-two-minute retrieval within claim windows.
Without this infrastructure, merchants submit Tier 4 photos and Tier 5 written accounts — not because they think it will win, but because it is the only evidence they have.
Banks know this pattern. Automated dispute review systems are specifically designed to process Tier 1 evidence efficiently and flag Tier 4 and 5 submissions for lower priority review. The evidence tier a merchant submits directly affects how the bank's automated system evaluates the case.
Building a Tier 1 Evidence System
The gap between merchants who win disputes at 65 to 90 percent and those who win at under 25 percent is almost entirely a Tier 1 evidence gap.
TrackVid closes this gap. It records every packing automatically when the shipping label is scanned, links each recording to the Order ID in real time, stores in indexed cloud, and retrieves any order's footage in under two minutes. The evidence created is Tier 1 — independently verifiable, timestamped, order-specific — and accepted by Amazon SAFE-T, Shopify Payments, eBay Money Back Guarantee, Visa CE3.0, and all major dispute mechanisms as primary evidence.
For the return side, a standardised opening video process at the returns receiving station creates Tier 1 return receipt evidence, completing the before-and-after chain.
Together, these two evidence layers answer every dispute question at the highest verification tier available.
> The dispute hierarchy is fixed. Banks evaluate evidence in order from most to least independently verifiable. The merchants with the highest win rates are the ones who submit at Tier 1 — not because they worked harder after the dispute, but because they built the infrastructure before it.

Frequently Asked Questions
What evidence wins ecommerce disputes in 2026?
The five tiers ranked by effectiveness: (1) order-linked packing video and return receipt video — independently verifiable fulfillment proof; (2) carrier delivery confirmation with signature for high-value orders; (3) prior undisputed transaction history and communication records; (4) product condition photos and listing documentation; (5) written accounts and order management records. The tier used determines the win probability more than any other factor. Merchants submitting Tier 1 evidence report win rates of 65 to 90 percent. Merchants submitting Tier 4 and 5 alone report rates below 25 percent.
What counts as proof in an ecommerce chargeback?
Proof in an ecommerce chargeback must independently verify the specific claim being made. For product disputes, this means evidence that shows what was in the parcel for the specific Order ID — order-linked packing video. For non-delivery disputes, this means delivery confirmation to the correct address. For fraud disputes, this means device and IP data plus prior transaction history. Written accounts and order management records are not independently verifiable — they tell the bank what the merchant says happened, not what the bank can verify happened.
Does a tracking number win a chargeback?
A tracking number wins "item not received" disputes when it shows confirmed delivery to the buyer's address. It does not win "item not as described," "wrong item received," or product condition disputes — for these, delivery tracking is irrelevant because the dispute is about contents, not delivery. Merchants who submit tracking numbers for product disputes consistently lose because the evidence does not address the claim.
Does packing video count as chargeback evidence?
Yes. Order-linked packing video is accepted as primary evidence by Amazon SAFE-T, Shopify Payments dispute resolution, eBay Resolution Center, and through Visa's Order Insight CE3.0 framework. It is evaluated as the highest-tier independently verifiable evidence for product disputes. Video submitted as part of chargeback representment that shows the correct product packed for the specific Order ID directly and independently answers the bank's question about what was fulfilled. Banks' automated review systems are specifically configured to process this type of structured evidence efficiently.
What do banks look for in chargeback evidence?
Banks' automated review systems evaluate evidence for three qualities: specificity (is this evidence for the specific transaction being disputed?), independent verifiability (can this evidence be verified without relying on either party's account?), and reason-code alignment (does this evidence address the specific claim made?). Order-linked packing video scores highest on all three for product disputes. Delivery confirmation scores highest for non-delivery disputes. Written accounts and general business records score lowest because they fail on independent verifiability.
