Ask HN: How to win most credit card chargeback disputes

While reading this reddit thread: https://www.reddit.com/r/Entrepreneur/comments/11mjiar/friendly_fraud_chargeback_abuse/ one of the commenters gave a very detailed, structured strategy he used to win 80% of his chargeback disputes after losing most of them initially.

Given that chargeback disputes are annoying and expensive for merchants/SaaS founders, what strategies have others used to win most of their disputes? And would you pay for a SaaS product to handle the whole process of gathering evidence and making a template to resolve chargeback disputes with the consumer/user and the card processor? It seems cumbersome and distracting for each business owner to come up with a strategy and manually execute on it every time a chargeback is issued.
