4 Biggest Call Center Outsourcing Companies in the US Now

    Call center outsourcing has been popular for decades now. But as companies grow more extensive and global, it’s become an even more viable strategy to optimize customer service operations. From cost savings, to expanding to more countries and time zones and delivering high-quality interactions, outsourcing can be a massive boon to your business.

    In this article, we’ll cover what you should consider when choosing an outsourcing vendor, the biggest contact center outsourcing companies in the US, some best practices for managing communications with your vendor, and what to look for in the future.

    What factors should you consider when choosing an outsourcing company?

    Naturally, choosing a vendor for your contact center outsourcing requires a lot of research. Some of the most important aspects that you should look for include:

    • Industry expertise and specialization. Look for companies that are already established and have proven experience within your industry or field. Showing experience with similar clients is an excellent indicator that they’re familiar with similar workloads or industries.
    • Scalability and flexibility. Ideally, your chosen vendor can scale up and down as demand changes. This can be incredibly important for businesses strategizing around holiday surges or specific windows of high call volume.
    • Technology and infrastructure. You’ll want to ensure your vendor is equipped with the latest technology and has an existing, robust infrastructure. Working with vendors that aren’t equipped to handle your call center effectively can dramatically impact the customer experience and your business’ reputation.
    • Quality assurance and compliance. Check to see if they have any pre-existing quality assurance software to ensure they have procedures in place for training and improving their customer service. Additionally, you’ll want to ensure they comply with regulations for your specific industry.
    • Cost-effectiveness and pricing models. While cost is a significant factor, it shouldn't be the only one. Evaluating your budget and how much you can save (or invest into) contact center outsourcing is key to making your dollar count. Additionally, keep an eye out for how some vendors set up their pricing models to ensure you don’t run into any hidden fees.
    • Reputation and trustworthiness. Research the company’s reputation. Look for reviews, testimonials, and case studies. Don't hesitate to ask for references and follow up with them to get a sense of the company's reliability and quality of work.

    How to evaluate the ROI of call center outsourcing

    Finding the best call center outsourcing providers is already challenging, but ensuring you’re going to benefit from outsourcing is critical, which means you’ll need to figure out your company’s return on investment (ROI). To evaluate effectively, consider dividing it into four critical segments:

    Define KPIs for measuring outsourcing success

    Setting clear and measurable KPIs is crucial when you start looking into outsourcing. These KPIs should make up your idea of success. These can include first call resolution rates, average call handling time, and customer satisfaction scores.

    Monitoring these data points can provide reliable indicators of how successfully your chosen outsourcing partner is performing against your set expectations.

    Calculate cost savings and operational efficiency gains

    While KPIs provide qualitative aspects, it’s equally important to consider a more direct cost-benefit analysis. Call center outsourcing can result in significant savings, reducing overheads like salaries, training, and infrastructural expenses.
    Compare these projected savings with your current costs to evaluate the immediate financial ROI. Just remember—the appeal of lower costs shouldn't overshadow the quality of service.

    Identify long-term benefits and strategic advantages

    Success in today's business environment often comes down to focusing on core operations and maximizing efficiency. Outsourcing partners usually possess extensive industry knowledge and experience. They can deliver service on par with (or even surpassing) in-house teams, freeing them up to focus on other aspects of your business.

    Evaluating the services your chosen vendor offers—and how it can affect your company once passed off to another team—is crucial when assessing whether the outsourcing ROI is worth it.

    Listen to agent and customer feedback

    Finally, listening to feedback can dramatically impact your call center. Gathering feedback from your customers, agents, and employees can help you accurately gauge the impact of your outsourcing.

    Use customer reviews, social media, surveys, and other means of communication to see how people are responding to your new call center, and make swift changes to ensure it continues to improve and boost your ROI. Collaborating with your outsourcing vendor on these issues can help lead to continuous improvement for you and your call center.

    Best practices for managing call center outsourcing relationships

    Developing a trusting, productive relationship between you and your call center outsourcing provider is critical. It requires active involvement and effective communication between both parties, which can be difficult to maintain. Here are some practical ways to manage and grow your relationship with your outsourcing vendor:

    • Establish clear channels of communication. Never underestimate the power of good communication. Regular, two-way communication is crucial for ensuring expectations are clearly understood and met. This also provides a platform for addressing any issues that may arise in the day-to-day, helping you solve problems as they happen.
    • Set clear performance metrics and KPIs. As we mentioned before, establishing KPIs is essential to ensuring your business is running smoothly. Tracking these KPIs and using them as indicators of your service quality is critical. They can help you communicate with your outsourcing partner when things need improvement or something has gone wrong.
    • Provide ongoing training and development. Your call center’s performance is central to your customer experience, so invest in your teams. While they may not be your direct employees, providing training and contextual information about your company, products, and services can significantly impact the customer experience. These training sessions allow for more informed and engaging conversations with your customers, leading to greater satisfaction and retention rates.
    • Conduct regular performance reviews. Regular reviews are a great way to analyze performance, highlight successes, and identify improvement areas. In these sessions, creating an environment that encourages open discussions is constructive. This will result in more actionable feedback, ultimately leading to better performance. You can also set incentives for better performance, such as rewards for reaching or maintaining specific KPIs, which can significantly boost team morale.

    Common challenges in call center outsourcing (and how to address them)

    While contact center outsourcing can offer plenty of advantages, it’s important to be aware of the challenges that might come with it. Identifying potential problems before they happen can help mitigate them and ensure a productive—and profitable—partnership.

    Loss of quality control and monitoring

    One of the most common concerns with contact center outsourcing is a drop in quality control, making it more difficult to track once it’s been outsourced. This can be dealt with by setting vital performance targets, establishing regular review processes, and using a robust quality assurance program, which can make a massive difference in the overall quality of your customer service.

    Lower customer service standards

    Outsourced agents may lack detailed knowledge about your products or services, leading to a lower customer service standard. If they continue to underperform and aren’t trained properly, it can result in a poor quality experience, which may lead to customers churning and a loss of revenue. To overcome this, create detailed knowledge bases and provide ongoing training.

    Data security and privacy concerns

    Connecting your databases with any third party can be a risk, even more so when you outsource customer interactions and information. You must evaluate and ensure your chosen outsourcing partner has robust data security protections and follows all relevant regulations. Without it, you put you and your customers at risk of data breaches and privacy issues.

    Language and cultural barriers

    Establishing smooth communications between you and your business is crucial because you’ll never know how your customers feel without it. Adding a third party to the mix can be difficult if they don’t speak the same languages as your customers or if cultures clash.

    Working with outsourcing vendors that have agents familiar with cultural norms and fluent in your customer’s native languages can prevent these issues from ever arising, which is easy to do when you’re looking at US-based call center outsourcing companies.

    Misaligned expectations

    Misunderstandings can arise due to misaligned expectations between businesses and call center providers. From the beginning, clearly define your expectations, deliverables, and KPIs. Regular communication and progress reviews can keep both parties aligned and proactively address concerns.

    Looking at future trends in call center outsourcing

    Technology is constantly advancing, and its impact on the call center industry moves just as fast. With so many new trends coming, it can be difficult to focus on what’s working and what isn’t. 

    Automation and AI integrations are massive parts of these new trends beyond just the applications of tools like ChatGPT. Robotic Process Automation (RPA) and AI technologies help boost efficiency and productivity. They can handle simple queries, freeing up agents to focus on complex customer issues requiring a human touch and critical thinking.

    Keeping your eyes on the horizon with evolving customer trends is important, too. Over the last few years, we’ve seen an increase in the need for an omnichannel approach, as customers want a seamless experience regardless of what platform they contact you on. Offering personalized customer experiences is also a growing trend, which makes using predictive analytics even more impactful.

    Finally, one of the biggest trends is outsourcing responsibly by focusing on sustainability and the social responsibility of outsourcing. Ethical operations, fair employment practices, and a commitment to environmental care factors are all growing trends in companies. With it, we can all shape equal opportunities and optimize the future for everyone.
