- Create, maintain, and deliver Customer Success Plans for each customer and partner, using Customer Tracker dashboards and Gainsight to monitor customer health, create Calls to Action, and manage risk.
- Deliver Quarterly Business Reviews (QBRs) in collaboration with Account and Channel Managers to review performance, value delivered, and future opportunities.
- Review adherence to operational SLAs and ensure appropriate success plans are in place to address any areas of non-compliance.
- Act as the voice of the customer, providing structured feedback to internal teams to improve products, services, and the overall customer experience.
- Support NPS and customer survey processes, ensuring customers are aware of and engaged with feedback initiatives.
- Maintain a strong understanding of customer contracts, subscriptions, and terms and conditions to maximise value for both the customer and IRIS.
