The US Bureau of Labor Statistics expects the number of customer service representative jobs to shrink by 5% over the next decade, and still projects about 341,700 openings in the role every year. Its occupational outlook puts the gap down to people leaving the job, which tells you most of what you need to know about running a support desk. Hiring is never finished. That constant churn is the main reason companies turn to customer support outsourcing companies: someone else recruits, trains and replaces the agents, and you manage the quality of the answers.
This list replaces an older version of this page that ranked review sites alongside actual providers. Every entry below is a real customer service outsourcing company that runs support teams for clients today, checked against its own website. They range from global contact center groups with operations in dozens of countries to smaller firms that build a dedicated team for a startup. We start with our own pick for companies that want to hire support staff rather than rent a contact center.

1. Zilo AI
Zilo AI is a recruitment and staffing company in Bangalore, and it comes at customer support from a different angle than the rest of this list. Instead of running a contact center for you, Zilo finds and places the people. Through its non-IT hiring services it recruits customer support executives who handle queries over phone, chat, email and WhatsApp, technical support executives who triage problems and pass clean tickets to engineering, support team leads who manage rosters and quality audits, and customer success managers and onboarding specialists for post-sale work.
Hires can be permanent, on contract for seasonal peaks, contract-to-hire so you can see an agent on the job before converting them, or brought on through volume hiring when you are opening a new team or location. Zilo also runs data annotation and AI evaluation work, which helps if your support team is training or checking a chatbot.
Best for: companies, in India or abroad, that want support staff on their own team or on contract, with remote talent from India as an option.
What to check: Zilo is a staffing partner, not a managed contact center. You supply the tools, the management and the service levels, so confirm you have a team lead in place, or hire one through Zilo, before the agents start.
2. SupportNinja
SupportNinja is a customer experience outsourcing company whose services run from day-to-day customer and technical support to onboarding, renewals, data operations and content moderation. It works mostly with SaaS, AI, ecommerce, healthcare, logistics and fintech companies, and names brands such as Happy Socks and Conga among its clients. It also sells human-in-the-loop operations for companies whose AI agents still need a person behind them.
Best for: growing tech and ecommerce companies that want a managed support team which can also cover adjacent work.
What to check: where your agents would be based, since the site does not say, and how they would be trained on your product.
3. Helpware
Helpware is a business services company with three divisions. Its CX division covers customer support, tech support, back office work and CX consulting, while separate tech and AI divisions build software and AI tools. That mix suits companies that want a support team and the back office tasks around it, such as order processing or data entry, from one provider.
Best for: mid-sized companies, including those in regulated industries, that want support and back office operations together.
What to check: delivery locations and languages, and whether the same team leads will stay on your account as it grows.
4. TaskUs
TaskUs runs customer experience, trust and safety, AI data operations and financial crime work from sites in 14 countries. For support, its appeal is capacity: a provider of that size can add agents quickly when ticket volume jumps after a product launch.
Best for: consumer apps, marketplaces and tech platforms with large and fast-changing volumes.
What to check: minimum team size. Large providers often prefer accounts with dozens of agents, not five.
5. Influx
Influx offers outsourced customer support in two shapes: you can hire individual agents from its vetted pool, or hand over a fully managed team with 24/7 coverage across American, European and Asia-Pacific time zones. Plans run month to month with no lock-in, which is unusual in this market and useful if you are testing whether outsourcing works for you.
Best for: ecommerce, SaaS and app companies that want flexible coverage, especially nights and weekends.
What to check: how agents are shared across clients on the lighter plans, and how quickly they can learn a technical product.
6. TELUS Digital
TELUS Digital, the business formerly called TELUS International and controlled by the Canadian telecom group TELUS, runs contact center outsourcing alongside customer care AI, AI training data and digital services. It suits companies that want their support operation and their automation roadmap handled by the same partner.
Best for: enterprises and well-funded scale-ups that want human support and AI tools from one provider.
What to check: which delivery countries would serve you, and how the AI layer is priced against human agent hours.
7. Concentrix
Concentrix is a global customer experience company whose services run from front-line customer care to enterprise protection work such as trust and safety. Large brands use it when they need support in many countries and languages under one contract.
Best for: global enterprises with multilingual, high-volume support.
What to check: how much attention a mid-sized account will get, and whether your agents will be dedicated or shared.
8. TP (Teleperformance)
TP, the company long known as Teleperformance, is a global outsourcing group that runs customer care, trust and safety and back office services for large brands. It also acquired the European provider Majorel.
Best for: enterprises that need support across many countries and languages, often combined with moderation or fraud work.
What to check: site locations, attrition on comparable accounts, and how service levels are measured and reported.
9. Foundever
Foundever is a global customer experience provider whose services include customer care, sales and retention, and collections. Banking, financial services and insurance are among the industries it lists, which makes it a fit for companies whose support desk also handles billing and payment conversations.
Best for: consumer brands and financial services companies that want care, sales and collections from one provider.
What to check: compliance experience in your industry, especially for payments and collections calls.
10. TTEC
TTEC describes itself as a digital customer experience technology and services company. It has two sides: CX consulting and technology, which designs and builds contact center platforms, and CX management services, which runs the support operation itself.
Best for: companies that want to redesign their contact center technology and staff it with the same partner.
What to check: whether you need both halves. If you only want agents, a simpler provider may cost less.
11. Sutherland
Sutherland calls itself an AI-driven business transformation company that designs, runs and automates the operations it takes over. Customer experience is one of its core services, alongside business process as a service, and insurance is among the industries it lists.
Best for: companies that want their support operation run and gradually automated.
What to check: how automation savings are shared, and what happens to service quality while processes are being changed.
How to choose a customer support outsourcing company
Decide first whether you want to rent a support operation or hire a support team. A managed provider like SupportNinja, TaskUs or Concentrix owns the hiring, training, tools and management, and you buy an outcome measured in response times and satisfaction scores. A staffing partner like Zilo AI fills seats on your own team, so you keep control of the culture and the product knowledge, and you carry the management.
Size matters more than most buyers expect. The global providers are built for accounts with many agents and can be slow to give a ten-person team their best people. Smaller firms such as Influx or Helpware often give a small account more attention, but may struggle if you need forty languages next year.
Ask every shortlisted provider for attrition figures on accounts like yours, since the BLS numbers above show how quickly agents move on. Ask who trains the replacements and how long a new agent takes to reach full productivity. Then run a pilot on a slice of real tickets for a few weeks, with your own quality reviewer checking a sample of answers, before you sign a long contract. If you want to build an in-house or contract support team with talent from India, contact Zilo AI.
Frequently asked questions
What do customer support outsourcing companies do?
They recruit, train and manage agents who answer your customers by phone, chat, email or social media, usually against agreed service levels. Many also handle technical support, onboarding, back office tasks and the human side of AI chatbots.
What are the best customer service outsourcing companies?
For global scale, Concentrix, TP, TELUS Digital and Foundever all run support in many countries. For growing tech and ecommerce companies, SupportNinja, TaskUs, Influx and Helpware are common choices. If you would rather hire support staff onto your own team from India, Zilo AI is our pick.
How much does customer support outsourcing cost?
Pricing is usually per agent hour, per agent per month, or per ticket, and depends heavily on location, language and how technical the work is. Ask for quotes on the same scope from at least two providers, and check what is included, such as team leads, quality review and tooling.
Should I outsource customer support or hire in house?
Outsource when volume swings a lot, when you need coverage around the clock or in many languages, or when recruiting is slowing you down. Hire in house, or through a staffing partner, when support depends on deep product knowledge or is central to how customers judge your brand.
Are review sites like Clutch or G2 outsourcing companies?
No. They are directories where buyers read reviews of providers. They can help you build a shortlist, but they do not run support teams, which is why they are not on this list.
