# Best Practices ## Comprehensive Data Collection The more data you store about your customers and their transactions, the easier it is to submit the right evidence to win disputes. We recommend securing the following transaction data: * contracts * order confirmations, invoices, and receipts * transaction logs * delivery receipts and shipping documents * courier tracking documentation * customer communication (emails, support tickets, chats) * transaction details (amounts, dates, times, account numbers) * authorization data (card verification details, checkout confirmations) * communication with your payment processors * IP addresses * date and time of downloads ## Communication Many disputes can be resolved through quick responses and proactive, open, and understanding communication. Here is what we recommend you: * Respond promptly to dispute notifications. * Proactively engage with customers. * Show understanding in your responses. ## Monitoring and Learning * maintenance of statistics * identification of patterns and risk factors * continuous learning * regular employee training --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.payrexx.com/merchant/english/payment/disputes/best-practices.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
