About Chargebacks911

Chargebacks911 is the original chargeback management solution. Others might copy our promises, but they can’t duplicate our results. We specialize in helping online businesses prevent chargebacks, minimize loss, mitigate risk, recover lost revenue, and enhance the customer experience. Our services were specially designed to handle the task of chargeback management in its entirety. Chargebacks911™ aims to liberate valuable resources so merchants can focus on retaining customers, increasing sales, and growing their business. Comprehensive solutions are customized for each individual business, negating the reliance on one-size-fits-all and error-prone strategies that are common throughout the industry. We are the only service provider to utilize the powerful combination of patented technologies, machine learning, and human forensics. This enables Chargebacks911 clients to experience long-term, sustainable ROI. Our firm was founded by former merchants who have a detailed understanding of the challenges businesses face on a daily basis. This enables us to create dynamic, agile solutions to address emerging industry threats. Our processes are proactive rather than reactive, meaning our clients are able to stay one step ahead of potential fraud. Headquartered in the Tampa Bay area, more than 300 global employees serve our international client base. As a subsidiary of Global Risk Technologies (GlobalRiskTechnologies.com), Chargebacks911 is able to offer scalable services to merchants in any industry. Learn more at Chargebacks911.com.
