In an era where customer experience is a key differentiator for businesses, contact centres sit at the front lines, serving as critical touchpoints between companies and their customers. Many organisations have invested heavily in sophisticated tech stacks to modernise their contact centres, often consolidating numerous functions—customer data management, automation, analytics, and communication channels—into a single platform or suite of tools. The intention is clear: simplify operations, reduce costs, and improve efficiency.
However, a growing number of contact centres are discovering that relying too heavily on a single technology stack—a practice known as “putting all eggs in one basket”—can lead to catastrophic failures. When that basket falters, it takes everything down with it, often crippling an organisation’s ability to interact with customers during the most critical moments. From data loss and operational downtime to security breaches and poor customer experiences, these failures are forcing companies to rethink their technological strategies.
75% of businesses relying on a single tech provider for their contact centres reported challenges with scalability and adapting to new technologies.
The Collapse of Tech-Stack Dependency
Several high-profile failures have illustrated the risks of placing complete reliance on a single vendor or platform. In late 2021, a well-known global telecommunications company experienced a five-hour outage in its contact centre systems. Customers in multiple regions were unable to access support, leading to thousands of missed inquiries. The company relied entirely on a single cloud provider, which managed its CRM, phone systems, and even the automated chatbots. When the cloud provider’s system went down, the entire infrastructure collapsed. The company faced weeks of damage control and lost revenue, with analysts estimating the financial impact to be in the range of $4 million.
The telecommunications company was far from alone. In the same year, a leading European financial services firm encountered a similar failure due to a single vendor’s software update that introduced critical bugs into the contact centre’s system. The result? Agents were left unable to access customer data, handle transactions, or communicate effectively with customers for two days, damaging trust and resulting in significant financial penalties from regulatory bodies.
Both of these cases highlight a fundamental problem: when a company ties its entire customer service operation to a single technology provider, any disruption to that provider can bring the entire system to a grinding halt. While the integration of multiple services into a singular platform can streamline operations and reduce costs in the short term, it createsa single point of failure that leaves contact centres highly vulnerable.
The Risks of Vendor Lock-In
The concept of vendor lock-in has long been a concern for businesses, but its consequences are more pronounced in contact centres due to the customer-facing nature of their work. Contact centres that lock themselves into one technology provider often lose the flexibility to adapt to changing market needs, implement innovative tools, or pivot in response to failures.
A survey conducted by Gartner found that 75% of businesses relying on a single tech provider for their contact centres reported challenges with scalability and adapting to new technologies, particularly as customer demands for omnichannel communication grow. When new channels such as social media or messaging apps gain prominence, businesses locked into outdated platforms struggle to integrate these services without massive overhauls.
Moreover, when organisations become overly reliant on one tech stack, they are subject to the pricing structures, service levels, and update schedules of the provider. If the vendor decides to raise prices or phase out certain functionalities, the business has little recourse without incurring massive migration costs. This creates a scenario where the vendor holds all the power, and the contact centre becomes a hostage to the decisions made by a single supplier.
Downtime Costs: The Financial Fallout
A significant but often underappreciated consequence
of a tech-stack failure in contact centres is the cost of downtime. According to research from IDC, the average cost of unplanned application downtime in contact centres ranges from $100,000 to $300,000 per hour, depending on the size and nature of the business. This figure does not even account for long-term damage to customer relationships, reputational harm, or regulatory penalties for service disruptions. For larger enterprises, these costs can quickly escalate. In 2022, a North American retailer with a heavily integrated contact centre platform experienced a nine-hour downtime, which led to an estimated $2.7 million in lost revenue from missed sales opportunities and service disruptions. The outage occurred due to a failure in their unified communications system, which was provided by a single vendor. Recovery was slow, and the company faced increased churn rates and decreased customer satisfaction scores in the months that followed.
The Shift Toward a Hybrid Technology Approach
In response to these failures, an increasing number of contact centres are shifting away from the monolithic approach of relying on a single vendor. Instead, they are adopting hybrid technology solutions that incorporate multiple systems from different providers. This decentralisation allows businesses to hedge against the risk of failure, as problems in one system do not necessarily lead to a total collapse of the contact centre’s operations.
For example, a financial services firm in the UK restructured its tech stack in 2023 after experiencing a series of outages related to its over-reliance on a single provider. The company adopted a hybrid system that combines multiple CRM platforms, telephony services, and AI-driven chatbots from different vendors. Not only has this improved the overall stability of their contact centre, but it also allowed the firm to more quickly adopt new technologies, like voice recognition and sentiment analysis, without waiting for updates from a single provider.
Gartner projects that by 2026, 60% of large contact centres will adopt a hybrid technology stack, moving away from the “all-in-one” solutions that have dominated the industry. Companies are increasingly realising that this multi-vendor approach not only reduces the risk of downtime but also fosters innovation and adaptability. As new communication channels, tools, and AI technologies emerge, contact centres with diversified tech stacks will be better positioned to integrate these innovations and meet evolving customer expectations.
Diversification as a Strategy for Stability
While the allure of an all-in-one technology solution is clear—simplified operations, lower short-term costs, and ease of management—the risks of putting all eggs in one basket are becoming too great for contact centres to ignore. The increasing complexity of customer interactions, the need for agility, and the high stakes of downtime mean that businesses can no longer afford to rely on a single provider for all their contact centre needs.
Diversifying the technology stack is not just a hedge against failure; it’s a strategic move that enables contact centres to remain agile, innovate more quickly, and deliver superior customer experiences. By embracing a hybrid approach, companies can mitigate the dangers of over-reliance and ensure that they are ready for whatever challenges and opportunities the future brings.
