Teleperformance is the largest customer service outsourcer by scale, with delivery centers worldwide, multilingual agent coverage, and enterprise-grade security and compliance programs. For a global enterprise that needs thousands of agents across languages and time zones, its scale is unmatched.
Enterprise minimums and custom pricing put it out of reach for small teams, and onboarding a large program takes time. Teleperformance suits enterprises with complex, high-volume programs where scale, compliance, and language coverage matter more than flexibility.
What we like- Largest global delivery network
- Multilingual coverage
- Strong enterprise security and compliance
Watch out for- Enterprise minimums and pricing
- Less flexible for small teams
- Onboarding can be slow

How we chose
We compared companies that provide outsourced customer service teams, excluding freelancer marketplaces and pure software vendors without agent delivery. Pricing figures come from each company's own site, checked in October 2026, and because outsourcing pricing is almost always custom, prices here are confirmed by proposal rather than stated as fixed rates. We weighed delivery scale, language coverage, channel breadth, technology platforms, quality focus, and fit for startups versus enterprises.
Compare proposals on quality, not just rate
Outsourcing proposals differ on agent experience, training, language fluency, and service levels, not just hourly rates. Ask for agent profiles, quality scores, attrition rates, and references from similar programs, and run a paid pilot before committing to a large contract. A low rate with high attrition and poor quality costs more than a higher rate with a stable, well-trained team.
Protect your brand in the contract
Define service levels, quality targets, data security requirements, and exit terms before signing. Include audit rights, brand voice guidelines, and a clear escalation path, since your customers will judge your company by the outsourced team's work.
Pilot programs before a full contract
A pilot program is the single best protection when outsourcing customer service, because it tests the provider's real performance before a large commitment. A good pilot runs for four to eight weeks, covers a defined slice of contacts such as one channel or one product line, and measures the same metrics the full contract will use: first response time, resolution rate, customer satisfaction, and quality scores. Both sides should agree on those metrics and on a pass threshold before the pilot starts, so the decision at the end is evidence-based rather than political.
Staffing the pilot correctly matters. The provider should assign the team that would handle the full program, not a showcase team that disappears after signing, and your company should assign a single owner who reviews interactions daily during the pilot. Daily review catches quality drift early, when it is cheap to correct, and builds the calibration habit that sustains quality after launch. Record every issue and how it was resolved, since that log becomes the playbook for scaling.
At the pilot's end, decide on data, not impressions. Compare pilot metrics with your in-house baseline or previous provider, survey customers who contacted the pilot team, and interview the agents about product gaps they found. If the pilot misses its thresholds, either fix the gaps with a second short pilot or walk away. A provider that resists a pilot, or demands a large commitment before any live testing, is signaling how the full relationship will feel.
One more clause deserves attention before signing: the exit plan. Contracts should define how data, conversation history, and knowledge base articles return to your company at the end of the relationship, how long the provider keeps copies, and what transition support it provides. Companies that skip this clause often discover that years of customer interaction history live in a provider's system they can no longer access. Negotiating the exit while both sides are enthusiastic is far easier than negotiating it during a dispute.
That exit clause also protects your customers, since a clean handover means their open cases and history follow them to the next provider instead of disappearing when the contract ends, which is exactly the continuity customers expect from a brand they trust.
Frequently asked questions
What is the best customer service outsourcing company overall?
For enterprises, Teleperformance or Concentrix, for scale and coverage. For startups and scale-ups, SupportNinja or PartnerHero, for dedicated teams without enterprise minimums.
How much does customer service outsourcing cost?
Pricing is almost always custom, based on agent count, language, channel, hours, and location. Expect per-agent monthly pricing, with rates varying widely by geography and complexity. Get proposals from several providers for comparison.
Should startups outsource customer service?
Often, yes, when support volume grows beyond the founding team's capacity. Start with a small dedicated team from a flexible provider, keep quality targets tight, and bring support in-house only when volume and complexity justify it.
What is the difference between dedicated and shared agents?
Dedicated agents work only for your company, learning your product and brand deeply. Shared agents handle several clients, which costs less but gives less product depth. Quality-focused brands usually choose dedicated teams.
How do I maintain quality with an outsourced team?
Set clear quality targets, review interactions weekly, share product updates promptly, and treat the outsourced team as an extension of your own. Regular calibration sessions between your team and theirs keep standards aligned.
