Best Call Center Outsourcing Companies in 2026

TP, the company formerly branded Teleperformance, is the largest listed provider of outsourced customer-experience and contact-centre services by revenue in this list. It reported 2025 revenue of €10,209m, down 0.7% on a reported basis but up 1.3% like-for-like, with Core Services (customer care, sales, back-office and data services for AI) growing 2.7% like-for-like and Specialized Services falling 9.3%, mainly because a large visa application management contract was not renewed. Its Specialized Services include collections, interpreting and localisation through LanguageLine Solutions, visa and consular services and recruitment process outsourcing. TP has grown through acquisitions: its release cites the integration of Majorel and the acquisition of ZP, consolidated from 1 February 2025, and of Agents Only from 30 June 2025. In February 2026 the board appointed Jorge Amar, described as an expert in AI-native customer operations, as group chief executive from 16 March 2026, with founder Daniel Julien and deputy chief executive Thomas Mackenbrock stepping down from executive roles. The company's Future Forward plan includes more than 500 AI projects under its TP.ai FAB unit in 2025. Its scale and language coverage suit global brands, but growth has slowed, and its 2025 net debt stood at about €4bn according to the same release.

Concentrix is a US-listed provider of customer-experience services and technology. For its 2025 fiscal year it reported revenue of US$9,825.8m, up 2.2%, with fourth-quarter revenue up 4.3% to US$2,552.9m. The company describes itself as designing, building and running integrated end-to-end solutions for more than 2,000 clients, from brand-experience design to AI technologies and digital operations. Its 2025 results included a non-cash goodwill impairment charge of US$1,523.3m in the fourth quarter, which the company attributed primarily to the trading range of its share price and market capitalisation, producing an operating loss for the quarter. President and chief executive Chris Caldwell said its investments were paying off in growth in its intelligent transformation solutions. For buyers, Concentrix offers scale comparable to TP together with design and technology services, though the impairment and low single-digit growth show the pressure on the sector. Pricing is negotiated per contract.

TTEC, founded in 1982, provides outsourced customer-experience operations through its TTEC Engage segment and CX technology design, implementation and managed services through TTEC Digital. Its 2025 revenue was US$2.137bn, down 3.2% from US$2.208bn, and it reported a GAAP loss for the year caused by a fourth-quarter impairment charge in a TTEC Digital reporting unit; fourth-quarter revenue rose 0.4% to US$570.0m. Chairman and chief executive Ken Tuchman argued that the company's knowledge of the full CX technology stack lets it bridge the gap for brands struggling to obtain returns from AI investments. TTEC's services cover customer acquisition and growth, technical support, back office and fraud prevention, and it says its employees operate on six continents. The combination of operations and technology consulting is its distinguishing feature: a client can have TTEC implement a contact-centre platform and then staff it. The revenue decline and impairment, however, point to pressure on its business.

TaskUs is a US-listed outsourcing company. It reported 2025 revenue of US$1.184bn, up 19.0%, a company record, and ended the year with 65,500 teammates and about 200 clients, 21 of which generated at least US$10m of revenue. Co-founder Bryce Maddock is chief executive, and its results release is datelined New Braunfels, Texas. TaskUs's 19.0% growth is the highest among the providers in this list that report revenue above US$1bn, and its record adjusted EBITDA of US$249.1m indicates that growth has been profitable. With about 200 clients, its client base is far smaller than Concentrix's 2,000-plus, so buyers may find each account receives more attention, while the company depends more on its largest relationships, 21 of which exceed US$10m a year.

Firstsource Solutions is an India-listed business-process management company. For its fiscal year to 31 March 2026 it reported revenue of ₹95,564m, up 19.7%, crossing US$1bn of annual revenue for the first time, with EBIT up 27.4% to ₹11,221m and reported profit after tax of ₹6,744m. The company described itself as positioned for growth in what it called the AI-native operational landscape, supported by large deal wins. Firstsource's 19.7% growth is the highest of any provider in this list that reports annual revenue, and its EBIT grew faster than revenue, indicating improving margins. Buyers should note that its revenue is reported in rupees, so US-dollar growth can differ from the figures above, and that, as a business-process management company, its services extend beyond the contact centre.

IBEX is a US-listed provider of outsourced customer-experience services and AI-enabled solutions. For its fiscal year to 30 June 2026 it reported record revenue of US$644.1m, up 15.4% from US$558.3m, and net income of US$46.3m, up 25.7%; fourth-quarter revenue rose 11.6% to US$164.3m, its sixth consecutive quarter of double-digit growth. Chief executive Bob Dechant said the company had delivered more than ten AI agent implementations across five industries and that this separated it from traditional BPO providers. Growth in the final quarter was led by its HealthTech vertical. IBEX is much smaller than the market leaders, which can mean more senior attention for mid-sized programmes, and its profitability improved in fiscal 2026. Its quarterly results also noted training costs from new clients and a temporary effect from moving work between nearshore and offshore centres.

Foundever is a privately held customer-experience company. It says its 130,000 people in more than 45 countries handle 3.3 billion conversations a year in more than 60 languages for more than 800 brands, drawing on 30 years of operations. In August 2026 it completed a recapitalisation, supported by 95.4% of its term-loan lenders and its existing majority shareholders, that reduced total debt by nearly US$900m, added US$225m of new common equity and extended debt maturities to 2030 and 2031; it named an interim chief executive at the same time. In October 2026 it appointed Pierre Barrial as chief executive, based in Atlanta, Georgia. Because Foundever does not publish revenue, it is placed after the listed companies in this ranking. Its headcount and language coverage put it among the largest providers worldwide, while its 2026 debt restructuring is a factor procurement teams may wish to assess.

TELUS Digital, previously known as TELUS International, provides digital customer-experience and digital-enablement transformation services. On 31 October 2025 its parent, the Canadian telecom operator TELUS, completed the acquisition of all TELUS Digital shares it did not already own, for US$4.50 per share in cash or TELUS shares, an aggregate consideration of about US$539m; TELUS now owns 100% of the business, and the shares were to be delisted from the Toronto and New York stock exchanges. Within TELUS, the business sits in the Digitally-led Customer Experiences segment, which covers digital customer experience and digital-enablement transformation services. As a wholly owned subsidiary it no longer publishes separate results, so it is placed after the companies that do. Its backing by a large operator is a source of financial stability, while the change of ownership may bring changes to strategy and management.

Alorica is a privately held US customer-experience outsourcer that says it has more than 25 years of CX expertise. Its website highlights Great Place to Work recognition across 11 countries and an expansion of its delivery network with a new site in Cagayan, in the Philippines. It does not publish revenue, headcount or a full country count on its homepage, so it is placed after the providers that do. Buyers should request audited financial information, site lists and security certifications during procurement.

Transcom is a privately held customer-experience outsourcer with a strong European presence. Its website states that its international team provides 24/7 coverage in more than 99 languages, which is broader language coverage than several larger providers advertise. The company promotes its sites as hubs for scalable support. Transcom does not publish revenue or headcount on its homepage, so it is placed at the end of this list. Its multilingual capability suits pan-European programmes, but buyers should confirm the countries and sites that would serve their programme.
