Assessing Your Core System’s Readiness for a Digital-First Present

Community banks have invested heavily in digital capabilities over the past decade. Online and mobile banking platforms are more modern, payment options are expanding and treasury management tools are far more capable than they once were. Yet many community banks still struggle to deliver the speed, flexibility and consistency customers now expect. The issue is rarely effort or intent, but more often, a quiet mismatch between digital-first expectations and core system realities. The question is no longer whether digital transformation matters. It’s whether your core system is ready for a digital-first present — not just a future roadmap.

PRI’s Mike Neale, Director of Systems and Automation, and Tom McGill, Head of Customer Experience, joined forces to describe how they see digital-first evolving in the industry today and the questions to ask to accurately assess whether your core is ready for the evolution.

Digital-First Banking is No Longer a Future State

Time does seem to pass more quickly every year, but if leaders are still looking at digital-first banking as something that’s a “coming soon” attraction, they’re already behind. It’s here now. Digital-first is not a generational trend or a strategic aspiration — it has become the primary way customers initiate financial relationships, and it holds true across a bank’s demographics.

The preference for digital delivery spans all age groups, with the only variation occurring in device preference, notes McGill. Today’s products and services are designed to work digitally by default. Branches are still important, but they’re no longer the starting point for the customer. Now the role of branches and bankers is to enhance the digital experience rather than compensate for its gaps.

“Digital-first doesn’t mean abandoning relationship banking, local decision-making or branch networks,” McGill said. “Community banks can maintain relationship banking while operating digitally first.”

Modern customer expectations align with digital-first banking as well. Customers increasingly assume:

• Balances and transactions are current and accurate
• Payments confirm immediately
• Account changes happen quickly
• Experiences are consistent across channels

“These expectations in a world where the ‘Amazon experience’ has become the standard place very real demands on aging core systems,” McGill said.

Why Core Systems Often Become the Limiting Factor

Despite widespread assumptions, most community banks (up to 98% in fact!) are not running modern cores. Most banks run their core banking operations on aging platforms deployed in the 1980s and 1990s, which were built for batch processing and branch workflows. These structures can create friction when asked to support real-time, event-driven digital expectations such as account changes and program enrollment.

However, many institutions can and do still deliver competitive digital experiences through layered innovation. Strong digital experiences can sit on non-modern cores, but frequently one or more aspects of the customer experience are below customer expectations. This will become more problematic  as customer expectations evolve. Additionally, operational considerations of deploying competitive experiences residing on non-modern cores produce operational inefficiencies.

Neale says common pressure points in the core include:

• Delayed balance and transaction visibility due to batch processing
• Product definitions that require vendor involvement to modify
• File-based integrations that slow data movement
• Limited real-time event visibility for digital channels

So, while digital layers, fintech integrations and middleware have enabled progress, experiences vary widely depending on architecture flexibility. Improving the “appearance” of a bank’s digital-first identity without upgrading the way it actually works for the customer is not good enough anymore, Neale said.

APIs Help — But They Don’t Automatically Modernize the Core

APIs, or Application Programming Interfaces, have become the industry’s preferred modernization path, but the presence of APIs alone does not guarantee digital agility. Functionality varies widely by provider. For example, some APIs retrieve data but do not support real-time events.

That said, incremental modernization is becoming the dominant strategy, with PYMTS.com estimating that nearly 47% of financial institutions are pursuing incremental core upgrades using APIs. Incremental core upgrades using APIs allow for gradual improvements and integration of new functionalities.

“APIs are emerging as a practical solution for modernizing banking infrastructure without complete overhauls. This method contrasts with the 13% of banks opting for full-core system replacements, highlighting the more manageable and less risky nature of API-driven updates. By adopting incremental modernization through APIs, banks can improve their digital capabilities and remain competitive in a rapidly evolving landscape.” – PYMTS.com

Five Questions to Assess Core Readiness Today

To determine whether your core is ready to level up its digital-first identity, consider the following questions:

1. How well does your core support real-time expectations?
Customers increasingly expectimmediate balance updates, real-time payment confirmation and instant alerts and notifications. Many banks rely on interim solutions such as memo posting, shadow balances or parallel ledgers to simulate real-time behavior. While these methods may have been historically effective at varying levels, solution providers now must develop more mature solution architectures. Understanding what truly updates the core in real time is a critical first step.  

2. Is your integration model API-first or file-first?
Modern digital ecosystems depend on APIs for real-time data exchange, event-driven updates and standardized integration methods. Knowing this, Neale suggests that community banks assess:

• How many integrations still rely on batch files
• Whether APIs support events or only data retrieval
• How much customization is required for each new vendor

“File-first environments increase operational friction as ecosystems grow,” Neale said. “That said, hybrid interfaces can help manage infrastructure demand for static data.”

3. Who controls product configuration — your bank or your vendor?
Digital-first banking demands flexibility in product setup, pricing and fee structures and tiered and relationship-based offerings. It also requires rapid experimentation, which becomes impossible when product changes depend on vendor timelines. When product changes require lengthy vendor processes, innovation can be suffocated regardless of how modern digital channels appear. 

“The ability to configure products quickly and safely is a strong indicator of core readiness,” McGill said.  

4. Is core data accessible, timely and usable?
Data accessibility has become the foundation of personalization, analytics and AI-driven banking decisions. Data underpins nearly every digital initiative. 

Banks should ask:

• How quickly can transaction-level data be accessed?
• Is data well-documented and consistent across systems?
• How much transformation is required before it becomes usable?

“When insights depend on overnight extracts and manual reconciliation, digital investments lose momentum,” McGill said. 

5. Does your core enable an ecosystem mindset?
Community banks increasingly rely on specialized partners for:

• Digital account opening
• Treasury management
• CRM and marketing automation
• Payments and fraud tools

A digitally ready core allows banks to integrate these partners and functions efficiently, change vendors without major disruption and avoid long-term lock-in. This is what Neale refers to as an “ecosystem mindset.”

The Real Shift: From Digital Projects to Core Capability

For many community banks, the past decade has been defined by successful digital projects such as launching mobile apps, expanding online account opening, adding payments functionality and improving treasury tools. Those investments mattered, and in many cases they worked well. Customers today can do far more digitally than they could even five years ago. But the competitive landscape has shifted. The question is no longer whether a bank offers digital services; it is whether those services operate with the speed, consistency and adaptability customers now assume as standard.

Digital-first limitations are rarely in the digital platform itself, but in the architecture beneath it. However, this does not mean community banks must replace their core systems. In fact, many institutions are proving that meaningful progress can come through incremental modernization — improving integration models, expanding API capabilities, enabling event-driven updates and strengthening data accessibility. The goal is not modernization for its own sake, but alignment: ensuring the core can support how customers already expect banking to work.
