Call center outsourcing is the smart solution to scale customer support without the high cost, and Stealth Agents makes it easy by providing top-tier virtual assistants who deliver 24/7 service with a 92% response rate. If you’re aiming for faster response times and happier customers without breaking the bank, Stealth Agents is your go-to partner.
The global call and contact-center outsourcing market is valued at around USD 97.3 billion in 2024 and is projected to reach about USD 163.9 billion by 2030, growing at a CAGR of roughly 9.8%.
As businesses increasingly outsource customer-experience functions to focus on core competencies, choosing the right provider becomes more than cost-cutting; it’s about quality, scalability, and strategic alignment. That’s why in reviewing the best call center outsourcing companies, it pays to look beyond industry giants and consider agile, responsive partners.
With Stealth Agents, you get tailored outsourcing solutions that combine global reach with boutique service levels, so you can deliver standout customer service without the complexity of managing it all in-house.
Despite having more ways to talk online, 61% of people still choose phone support over options like email and live chat.
This shows how important it is for businesses to have a strong team ready, or a lead-generation virtual assistant, to answer calls.
In recent years, the demand for call center services has surged, fueled by the rapid growth of e-commerce and digital transformation.
Modern call center operations handle complex business functions: processing customer complaints that prevent churn, capturing lead information that feeds your sales pipeline, and identifying product issues before they become costly problems. Without dedicated phone support, businesses lose an average of 23% of potential customers who abandon purchases due to unresolved questions.
Today’s customers expect swift, high-quality support, and missing the mark can cost more than just a sale; it can impact your business’s reputation and long-term growth.
What Are Business Process Outsourcing (BPO) Companies?
Business Process Outsourcing (BPO) companies are specialists that handle essential business tasks for other organizations, allowing companies to focus on what they do best. Instead of stretching your internal team thin, you can delegate time-consuming or complex processes to external experts.
BPOs manage a wide range of functions, such as:
- Customer support and call center operations
- Data management and entry
- Market research and analytics
- Payroll administration
- Accounting and bookkeeping
- Social media and digital marketing
Why More US Companies Are Turning to Latin America for Talent
Many US businesses are increasingly looking south when it comes to building out their teams, and it’s not hard to see why. Hiring professionals from Latin America combines impressive cost-effectiveness with strategic advantages often missing from traditional outsourcing.
First, the financial benefits are compelling. Companies can tap top-tier talent while saving anywhere from 30% to 70% compared to hiring domestically, without sacrificing quality. But cost isn’t the only reason for this shift.
Latin American professionals typically work in time zones that align closely with US operations. This minimizes communication delays, supports real-time collaboration, and avoids the late-night or early-morning complications common with offshore teams in Asia.
Cultural compatibility is another key factor. Shared business practices, English proficiency, and strong customer service values, shaped by major brands like American Express and Dell operating in the region, make integration smoother and long-term partnerships more successful.
Finally, building a dedicated remote team in Latin America gives companies greater flexibility and control. Rather than constantly rotating freelancers or distant call centers, businesses enjoy the loyalty, training consistency, and team spirit of an in-house staff, while still reaping the benefits of global hiring.
That’s why more US firms, from fast-growing startups to Fortune 500s, are making Latin America a cornerstone of their workforce strategy.
Projected Growth of the Global BPO Market
If you’re wondering just how fast the business process outsourcing (BPO) industry is expanding, the numbers speak volumes. The global BPO market, already a massive industry, currently exceeds $350 billion. But that’s just the beginning, market analysts predict it will surge to an impressive $440 billion by 2028.
This rapid growth is driven by companies worldwide seeking efficient solutions for operations like call center management, accounting, payroll, data entry, social media management, and market research. As businesses look for ways to streamline processes and stay competitive, it’s no surprise that the BPO sector continues to gain momentum on the global stage.

Nearshore vs. Offshore BPO: What’s the Difference?
When exploring business process outsourcing (BPO), you’ll often hear the terms “nearshore” and “offshore” tossed around, but what sets them apart?
- Nearshore BPO means partnering with service providers in countries that are geographically close to your own, think a U.S. company working with teams in Mexico or Colombia. The perks here? Similar time zones, easier travel for in-person meetings, and often a greater overlap in culture and language expectations. This can make collaboration and communication smoother.
- Offshore BPO, on the other hand, involves outsourcing work to far-away destinations like India, the Philippines, or Eastern Europe. Offshore providers are well-known for offering cost savings due to lower labor costs, but you may have to navigate bigger time zone differences and possible cultural or language barriers. That said, offshore BPOs like Teleperformance or Concentrix are favorites for businesses looking for 24/7 support and scalability.
• First Call Resolution (FCR)
First Call Resolution, often called FCR, is a key measure for call centers. It tracks how often customer issues are fully resolved in the first interaction, without the need for callbacks or follow-ups.
Why does this matter? When customers have their concerns addressed promptly, they leave feeling happier and more valued.
That sense of satisfaction can boost a business’s reputation and encourage loyalty.
For businesses, a higher FCR means less time and resources spent handling repeat contacts.
As call centers become more efficient, agents can focus on new queries and costs stay in check, all while keeping customers satisfied.
