For background on how representment and evidence work, see [What Are Disputes?](/guide#merchant-disputes). ## How Evidence Review Works When you file a non-fraud case, Decisionly performs two types of AI-powered analysis: ### Documentation Review Analyzes uploaded evidence files to determine if they're relevant and valid for the case. Each file is reviewed to check: * Is the document related to the disputed transaction? * Does it support the dispute reason? * Is the document clear and readable? Files marked as invalid don't prevent filing by default, but indicate the evidence may not support the chargeback. ### Conditions Review Analyzes case details and evidence to determine if evidence guidelines are met. The AI checks: * Whether all chargeback conditions are satisfied * Which conditions were detected as met * Which chargeback conditions were not detected This analysis is informational by default and doesn't prevent filing. However, filing a chargeback without meeting evidence guidelines may result in the merchant successfully disputing it. ## Workflow Rules You can configure [workflow rules](/workflow-rules) to control how cases are handled based on AI analysis results. The workflow rules to set up are **Evidence Review Passed** and **Documentation Valid**. **Evidence Review Passed** determines whether a case meets all evidence guidelines for its dispute reason. You could use this rule to **flag for review** when evidence guidelines are not met. **Documentation Valid** determines whether uploaded evidence files are relevant and valid. You could use this rule to **flag for review** when documentation is marked as invalid. ## Dispute Reason Conditions Each dispute reason has specific conditions that should be met to file a valid chargeback with the card network. The AI analyzes your case details and evidence to determine which conditions are satisfied. ### Product Not As Described All of these conditions should be met: * **Merchant Contacted** - The cardholder contacted the merchant, or attempted to contact the merchant, to resolve the dispute * **Merchant Refused Remedy** - The merchant refused to adjust the price, repair, or replace the goods, or issue a credit * **Product Returned** - For physical goods: The cardholder returned the goods or informed the merchant the goods were available for pickup Additionally, **at least one** of these conditions should be met: * **Product Broken** - When delivered, the goods arrived broken or could not be used for the intended purpose * **Product Not As Described** - Goods and services did not conform to their description (wrong color, size, quality, etc.) * **Contract Terms Not Honored** - The merchant did not honor the terms and conditions of the contract, including money back guarantees, written promises, or return policy ### Product Counterfeit All of these conditions should be met: * **Merchant Contacted** - The cardholder contacted the merchant, or attempted to contact the merchant, to resolve the dispute * **Product Counterfeit** - 3rd party verification that the product is counterfeit ### Product Not Received All of these conditions should be met: * **Merchant Contacted** - The cardholder contacted the merchant, or attempted to contact the merchant, to resolve the dispute * **Product Description** - A reasonably specific description of the goods/services purchased is required ### Duplicate Charge **At least one** of these conditions should be met: * **Prior Transaction Details** - Details of the prior transaction providing sufficient details to allow the merchant to locate the prior payment * **Prior Transaction Documentation** - When a non-credit card method of prior payment was used, documentation detailing the specific non-credit card method of payment (bank statement, cleared check, or cash receipt) ### Incorrect Amount The following condition should be met: * **Correct Amount Documentation** - Documentation detailing the correct transaction amount (receipt, final bill, or merchant email confirming price) ### Credit Not Processed The following condition should be met: * **Merchant Contacted** - The cardholder contacted the merchant, or attempted to contact the merchant, to resolve the dispute Additionally, **at least one** of these conditions should be met: * **Refund Not Processed** - The merchant agreed to provide a refund and failed to process that refund * **Partial Credit** - The merchant posted a credit for a reduced amount without proper disclosure ### Subscription Canceled The following condition should be met: * **Merchant Contacted** - The cardholder contacted the merchant, or attempted to contact the merchant, to resolve the dispute Additionally, **at least one** of these conditions should be met: * **Subscription Canceled** - The cardholder notified the merchant to cancel the recurring transaction and the merchant continued to bill the cardholder * **Subscription Not Disclosed** - The transaction was not advertised as recurring ### Canceled or Returned The following condition should be met: * **Merchant Contacted** - The cardholder contacted the merchant, or attempted to contact the merchant, to resolve the dispute Additionally, **at least one** of these conditions should be met: * **Canceled or Returned** - No credit has been issued/processed for the canceled services or merchandise * **Refund Policy Not Disclosed** - The merchant failed to disclose its refund policy at the time of the transaction and is unwilling to accept a return or cancellation * **Timeshare Cancellation Not Processed** - A Timeshare cancellation was not processed within 14 days of the contract or receipt date * **No-Show Fee Charged** - A guaranteed reservation was canceled and the customer was charged a No-Show Fee ### Cash Not Received The following condition should be met: * **Cash Not Dispensed** - Some or all of the funds debited from the cardholder's account were not dispensed by the ATM or point of sale terminal ### Other The following condition should be met: * **Cardholder Dispute** - The dispute is about a transaction with a merchant or issues with the transaction itself, not problems with the issuer such as billing errors, credit balance transfers, account management issues, or other issuer-related matters
