FIS Reviews, Ratings & Features 2026 | Gartner Peer Insights

Gartner deﬁnes a core banking system (CBS) as the financial institution’s back‐ofﬁce software that performs real-time or end-of-day processing for deposits and loans. Apart from advancing the processing dates, representative capabilities include transaction posting, interest accrual/payment, service charge calculation and cash management (zero balance, target balance). CBSs provide deposit and loan product servicing with interfaces to other applications, such as customer-facing channels, general ledger systems and reporting tools. CBSs can be deployed on the bank’s premises or run from the cloud or any hosted environment. Bank employees and customers either directly or indirectly use the bank’s CBS.
The CBSs of a financial institution’s back‐ofﬁce software perform either real-time or end-of-day processing for deposits and loans. Apart from advancing the processing dates, representative capabilities include transaction posting, interest accrual and posting, service charge calculation and cash management (zero balance, target balance). All these processes and steps imply a business model based on conventional banking principles that imply interest accrual on accounts and profitability from any lending practice. Therefore, CBSs, by definition, implicitly exclude Islamic CBSs that, to the contrary, use Islamic financial tools to back Shariah-compliant business models that require different mechanisms to produce profits.

FIS has truly stepped up their efforts in delivering quality solutions and improved levels of service. They are actively listening to their clients' needs, making significant, impactful efforts to modernize their offerings, enhancing their customer engagement model to ensure ease and speed to resolution, actively seeking feedback from their clients and actually taking action. We expect problems, and nothing is perfect with any core/Tech provider, but it's how those problems are resolved (speed/ease) that truly makes a difference. Over the past year, I've been impressed with the efforts and outcomes. From resource alignment, to enhancing the ways in which we can effectively communicate, FIS is making great progress here. Several areas are works in progress, and the path to that progress is very promising.

We are rating the overall as "Average" as there is no ability to choose between that and "Outstanding", which in our mind is a large jump in ratings. IBS delivers a quality product, with marked improvements in the modernization of the core. The connections we have made within FIS, most specifically our Account Manager, is what truly makes the relationship a positive one. Client engagement and collaboration between FIS and the IBS clients, and between the clients themselves, is excellent. Feedback is often sought out from customers, and is used to influence change and investment.  

VP, Operations

For our bank, FIS continues to demonstrate why their IBS platform remains a trusted cornerstone: providing reliability and forward-looking innovation. At its core, IBS delivers a powerful combination of breadth, stability, and adaptability essential to our ability to compete with large national banks. Beyond the technology itself, FIS has clearly invested in strengthening its client partnership model. For this reason I'm rating IBS 5 stars. There is now a noticeable emphasis on listening to clients, acting on feedback, and continuously improving product and service delivery. Communication channels have become more effective, support responsiveness has materially improved, and there is a genuine sense that client voices influence the product roadmap. This collaborative approach is reinforced by IBS's active and engaged user community, a valuable forum for sharing best practices and providing direct input regarding the platform's future direction.
