Having spent 22 years working alongside Colombia's leading financial institutions, I’ve learned to recognize when a technical conversation stops being just a trend and becomes a critical business decision. Bre-B is exactly that moment. This is not "just another payment methods project"—it is the most profound shift in the rules of the game that the Colombian financial system has seen in a decade.

And I say this from firsthand experience. Just a few weeks ago, I was at PayTech, listening directly to the Bre-B lead from the Banco de la República explain what lies ahead. I left that room with an uncomfortable certainty: most institutions are focusing heavily on the integration itself, while very few are looking at what will actually be painful—sustaining operations under pressure.

Getting connected to Bre-B was just phase one, and many institutions rushed to make it happen. But adoption has skyrocketed faster than almost anyone projected. In less than eight months of operation, the system has already reached nearly 35 million linked users, over 105 million registered keys, and a volume exceeding 780 million transactions—with peak days hovering near 5 million operations.

These numbers change the nature of the problem. When a system handles millions of daily operations, 24/7, including holidays, the question stops being "Does it work?" and becomes "Does it work always, under any load, without crashing?" In instant payments, 99.99% availability has stopped being an architectural luxury and has become the new competitive standard. Every minute of downtime means money that isn't moving, trust that is lost, and a customer going back to cash.

In instant payments, you don't compete by just having the feature. You compete by making sure that feature never fails. And you don't test that in production—you test it beforehand.

The discussion at the Banco de la República was clear: this is just the beginning. Phase two expands the system's reach with new participants and services. Among the initiatives already underway for this year are real-time withdrawals from investment funds (fiduciaries), the widespread adoption of peer-to-peer QR code payments, and the onboarding of new players—including cooperatives that are accelerating their modernization to avoid being left behind.

Each of these features is a new surface that can fail. Every integration with a legacy system, every new transaction flow, and every participant entering the ecosystem multiplies the potential points of failure. And here is the point I want to make absolutely clear to those leading banking technology: complexity is going to grow faster than your teams. The only way to sustain quality at this pace is to industrialize quality assurance.

I don’t speak from theory. I speak from the projects where we’ve rolled up our sleeves alongside Colombian financial institutions. Here are the key lessons that become critical in the context of Bre-B:

• Tokenization and Digital Wallet Security: We have guided QA and automation strategies for payment method tokenization, elevating security and reducing operational risk without slowing down business delivery. In an interoperable system like Bre-B, security isn't just a module—it’s the entry requirement.

• Performance Testing on Critical Systems: We have validated the performance of banking portals and services under heavy demand, including cloud migrations, guaranteeing stability, scalability, and optimal response times. This is exactly the kind of testing that separates an institution that survives a transactional spike from one that lands in the headlines due to a system crash.

• Legacy Core Integration: We have connected digital payment and transfer platforms with legacy banking cores—including AS/400 architecture—without rewriting the system and while keeping operations completely stable. The reality of Colombian banking is that Bre-B sits on top of infrastructure that has been running for decades. In this scenario, QA is what prevents modernization from breaking what already works.

• Critical Workflow Automation: We have transitioned quality assurance cells from manual validation to automated coverage exceeding 70% in critical processes, reducing risk and dependency on human reviews. At the speed of Bre-B, if it isn’t automated, it doesn’t scale.

Let's be honest about where the real breakthrough lies. For years, quality assurance was viewed as the department that "slows down" deployments. In the world of instant payments, that logic is completely flipped: QA is what allows you to deploy fast and sleep soundly at night. And artificial intelligence is making that equation a reality.

By applying AI to testing, we can generate and maintain test cases at the exact speed the business evolves, anticipate failure points before they ever hit production, and simulate load and stress scenarios that were previously impossible due to cost or time constraints. At Q-Vision, we built this capability directly into our own platform, IzyTesting, precisely to turn quality assurance into a business driver rather than a bottleneck.

If these 22 years have taught me anything, it's that opportunities in this industry don't wait around. Knowledge that isn't turned into action remains nothing more than a good hallway conversation while the market moves forward. Bre-B presents all of us—institutions and technology partners alike—with the exact same choice: act in time, or spend your time catching up.

My recommendation for banking tech leaders is to treat the availability and resilience of your Bre-B operations as a strategic priority, not a technical chore. Audit your testing capabilities today. Ask yourself if your QA can scale at the pace your transaction volume is about to grow. And if the answer raises any doubts, let’s talk before a peak traffic surge answers it for you.

At Q-Vision Technologies, we have spent more than two decades doing precisely this: ensuring that the software of the country's most demanding companies works when it matters most. Bre-B is the next big test. And quality, as always, is proven before the customer ever notices.
