Datos Insights found that 51% of U.S. banks and credit unions reported client-impacting issues after technology implementations, and 66% missed expected implementation deadlines. The study, conducted on behalf of Go-Live Faster, surveyed 61 institutions with assets from $5 billion to $100 billion.
Why it matters
Delayed or problematic system changes can disrupt customer accounts and strain institutions' budgets, with 46% reporting they exceeded implementation budgets on their most recent project. The findings point to integration and testing as persistent weak spots for mid-sized U.S. financial institutions.
Of 61 U.S. banks and credit unions surveyed, 46% exceeded their budgets on their most recent implementation and 18% saw above-normal client attrition after a migration. Estimated monthly delay costs ranged from $100,000 to $400,000 for about half the institutions, though the study does not address how these costs compare with prior periods.

The details
Integration complexity was the leading cause of implementation delays, cited by 85% of institutions, followed by test data or migration problems at 70% and internal resource constraints at 42%. Some 66% rated their system integration and user acceptance testing as no better than adequate for complex platform changes, and just 3% had fully implemented AI in testing. Institutions often rely on outside help, with 79% using partners for implementations, and 64% reported pressure to accelerate timelines.

Market Landscape
The findings reflect ongoing pressure on mid-sized U.S. banks and credit unions, which must modernize core systems while competing with larger institutions and fintech providers. The reliance on outside partners at 79% of institutions suggests a market where implementation expertise is increasingly outsourced.
Customers of banks and credit unions may experience service disruptions or account issues when their institution rolls out new systems. Consumers can ask their institution about planned technology changes and how client support will be handled during transitions.
The takeaway
Banks and credit unions planning system upgrades should prioritize integration and testing capabilities before launch to reduce client disruption. Customers can benefit from asking how their institution will protect service quality during any major technology change.
