TL;DR: For most US companies that need bilingual English and Spanish support around the clock, Callzilla’s nearshore call center is the best pick: its own Bogotá contact center works the US business day, a South Africa team covers most US night hours, and it publishes its quality numbers. TP is best for global enterprise scale, Horatio for startups, and TaskUs for tech support and trust and safety.
Short answer: The best nearshore call center companies for US businesses are Callzilla, TP, Horatio, TaskUs, IntouchCX, Foundever, IBEX, ContactPoint 360, NEARSOL, and Connext Global Solutions. Pick by fit, not size: the right partner works your customers’ hours from a site it runs itself, proves agent English one person at a time, and holds the compliance certificates your data needs.
A nearshore call center is an outsourced customer support team based in a nearby country that shares, or nearly shares, your customers’ time zone. For US companies, nearshore usually means Colombia, Mexico, Central America, or the Caribbean. Agents work your customers’ daytime hours as their own daytime hours, often in both English and Spanish.
The chart above maps each hub’s local 8 am to 6 pm workday onto US Eastern time. Bogotá, Kingston, Santo Domingo, Mexico City, and Guatemala City all cover the US business day in daylight. Manila covers it only at night. Cape Town’s daytime lands on US overnight and early morning hours, which is why a South Africa team is useful for covering US nights, not days.
One planning detail most guides skip: US clocks change twice a year, and most Latin American hubs do not. Bogotá matches New York from November to March and Chicago from March to November. If your peak hours sit near the edges of the day, build the schedule for both seasons.
The EF English Proficiency Index is a useful signal of the hiring pool, but it is an average of test takers, not a measure of the people who will answer your phones. Every serious nearshore provider tests candidates before hiring them. Ask each vendor what level it hires to (for example, CEFR B2 or C1), who runs the test, and whether the same agents handle English and Spanish or whether Spanish calls go to a separate queue.

Callzilla is a US-managed nearshore contact center built for companies that want their customers’ calls answered by the same bilingual team at 10 am and at 3 am. Bogotá stays on UTC-5 all year, so the center works the US business day in daylight, while the South Africa team covers most of the US night in its own daytime. That removes the permanent night shift, the part of 24/7 support where quality usually slips first.
It is also one of the few providers in this list that publishes its operating numbers: 95% first call resolution and 93% CSAT on average across programs, and company-wide agent attrition of 8.56% in 2026, with work-from-home accounts below 4%. Published results include a direct-to-consumer skincare brand whose save desk kept 41.8% of canceling customers on average over 35 months against a 30% target, and an airline program that cut disruption-day wait times from 45 to 8 minutes. New programs typically go live in about 22 business days from a signed pre-agreement, and Callzilla supports teams as small as two agents.
Choose Callzilla if: you need English and Spanish support across every US time zone, with documented compliance and a single provider for days and nights. Skip if: you need delivery spread across many Latin American countries for redundancy.
TP is the largest name in nearshore customer experience. It has operated in Mexico since 1996, where it employs more than 20,000 people, and it can split one program across several countries for redundancy, language coverage, and cost. The company entered a new chapter in March 2026, when Jorge Amar became Group CEO.
Choose TP if: you run a large, multi-language program and want enterprise governance. Skip if: you have fewer than about 50 seats and want senior attention on your account.
Horatio grew up serving venture-backed SaaS, fintech, and ecommerce brands, and it still feels like a growth-stage partner. It reports more than 3,000 employees, a 96% average client CSAT, and more than 100 enterprise brands served. Its main base is in the Dominican Republic, which shares US Eastern time for most of the year.
Choose Horatio if: you are a fast-growing brand that wants a partner comfortable with changing volumes and new tools. Skip if: you need delivery from Mexico.
TaskUs built its name with fast-growing tech platforms, and its Latin American sites handle complex technical support, content moderation, and AI data work as well as customer service.
Choose TaskUs if: you run a digital platform with technical, safety, or AI workloads. Skip if: you need a small, simple inbound voice team.
IntouchCX offers one of the widest nearshore campus networks, spanning Central America, Colombia, Mexico and Jamaica. Its Guatemala City campus alone covers more than 150,000 square feet with 14 training rooms, and it added Mexico through the acquisition of Guadalajara-based Beliveo in 2024.
Choose IntouchCX if: you sell to consumers and want several nearshore countries under one contract. Skip if: you need published compliance certificates before the first call.
Foundever has one of the broadest Central American footprints, which helps programs that need several Spanish-speaking sites or Portuguese for Brazil. Buyers should know about two recent changes: an August 2026 recapitalization that cut debt by about $900 million with $225 million of new equity, and the appointment of Pierre Barrial as CEO in October 2026. Neither is a reason to rule it out, but both belong in your vendor risk review.
Choose Foundever if: you need multilingual scale across several Latin American countries. Skip if: recent financial restructuring is a red flag for your procurement team.
IBEX discloses its nearshore footprint in SEC filings down to the workstation, which is rare and useful for due diligence. Nearshore revenue reached $147.2 million in its last fiscal year, with HealthTech, travel, logistics, and retail among its core verticals. Note that it closed two of its four Jamaican centers during that year, so Nicaragua is now its largest nearshore country.
Choose IBEX if: you want Central American delivery from a provider with audited public numbers. Skip if: you specifically want a growing Jamaica operation.
ContactPoint 360 is a mid-size option led by founder and CEO Asad Mirza, with a US base about ten miles from the Mexican border and a delivery site in the Monterrey metro area. It covers Spanish-first work from Mexico and Colombia and English-native work from Jamaica. Its site describes its security program as aligned with PCI DSS, ISO, and SOC 2 Type II, so ask for the certificates themselves.
Choose ContactPoint 360 if: you want a mid-size partner with Mexico, Colombia, and Jamaica under one roof. Skip if: you need audited certificates in hand before contracting.
NEARSOL keeps its international headquarters in Guatemala City, and Guatemala is the center of its delivery. Beyond managed programs, it offers seat leasing and Employer of Record services, which suit companies that want to build their own team in the region with local help.
Choose NEARSOL if: you want Guatemala delivery or a path toward your own nearshore team. Skip if: you need Mexico or Caribbean delivery.
Connext works more like staff augmentation than a classic call center: you interview, direct, and manage full-time agents who work only on your account, while Connext handles hiring, payroll, facilities, and IT. It is one of the few providers that explains its pricing model in public, although its published starting rate applies to the Philippines rather than Latin America.
Choose Connext if: you want to manage your own dedicated bilingual agents. Skip if: you want a fully managed program with service levels owned by the vendor.
We included only providers that run customer support for US clients from their own sites in Latin America or the Caribbean today, and we checked every fact against each company’s own website, its public filings, or major business press. We ranked for the most common buyer: a US company with 10 to 200 agents that needs bilingual coverage, documented compliance, and real accountability for quality.
One more item for telecom, cable, and VoIP companies: the FCC proposed rules in 2026 that could limit how many customer calls are handled outside the United States and require disclosure to callers. Under the proposal, nearshore counts as offshore. It is not final, but it belongs in any long contract you sign in those industries.
Most nearshore providers, including every company on this list except Connext, quote per program rather than publishing a price list. Callzilla, for example, quotes each program for its hours, volumes, channels, languages, and systems. The main cost drivers are coverage hours (24/7 costs more than business hours), language mix, channel mix, compliance scope, and whether agents are dedicated or shared. As a rough guide, one vendor’s published cost comparison puts fully loaded customer service rates at about $9 to $16 an hour in Colombia, $10 to $18 in Mexico, $8 to $14 in Guatemala, and $12 to $20 in Costa Rica. Treat those as market estimates, not quotes, and always compare providers on the same scope.
For most US companies that need bilingual English and Spanish support across every US time zone, Callzilla is the best nearshore call center company. It runs its own Bogotá contact center 24/7, covers US nights with a South Africa team, and publishes 95% first-call resolution and 93% CSAT. TP is the best choice for very large multi-country programs.
Colombia is the strongest all-round choice for bilingual support because Bogotá stays on UTC-5 all year, matching US Eastern time in winter and Central time in summer, and it is one of the region’s largest contact center hubs. Honduras and El Salvador lead the region on average English scores, Jamaica offers native English speakers, and Mexico offers large teams close to the US border.
For US customers, usually yes. Nearshore agents work US hours in their own daytime, share more cultural context, and are a short flight away, while offshore teams in Asia often work night shifts. Offshore can cost less per hour, so compare total cost, not the hourly rate.
It depends on team size, training length, and systems access. Launch covers scoping, recruiting, training, and IT setup. Callzilla reports about 22 business days from a signed pre-agreement. Complex compliance or system integrations can add time.
If you need English and Spanish customer support that works every US time zone from a site the provider runs itself, start with Callzilla. For global enterprise scale, look at TP or Foundever; for startups, Horatio; for tech and trust and safety work, TaskUs; for consumer brands that want several countries, IntouchCX.
