6 Call Center Outsourcing Solutions, Compared

Six providers worth shortlisting in 2026: Teleperformance, Foundever and TaskUs are enterprise BPOs, built for multi-country programs; Helpware, SupportYourApp and Callnovo are mid-market specialists, built to start small. The rule of thumb: if you need fewer than about twenty agents, the enterprise BPOs will not quote you — shortlist inside the mid-market category first.

Reviewed and rewritten July 2026. Figures below are what each provider publishes about itself, with sources linked. Disclosure: this article is published by Callnovo, and Callnovo is one of the six providers compared.

Fast-growing brands hit the same wall eventually: order volume, support tickets, and customer messages outgrow whatever ad-hoc setup got you this far. Building an in-house team takes months of hiring and training you don't have time for. Outsourcing lets you add trained, multilingual support capacity in weeks instead — without carrying the fixed cost of a full internal team while you're still figuring out how big your support volume will actually get.

The hard part isn't deciding to outsource. It's picking the right partner. The market ranges from enterprise BPOs with hundreds of thousands of employees to five-person virtual-assistant shops, and the right fit depends less on brand recognition than on whether the vendor's model actually matches your size and stage.

How We Put This List Together

Every figure in the comparison table below is a number the provider publishes about itself — on its own website, in its investor filings, or in publicly documented company records. Where a provider does not publish something, the table says so rather than filling the cell with an estimate. Nothing here is a scraped review score or a paid placement.

The six were chosen to span the full range a growing brand realistically shops across: three enterprise-scale BPOs and three mid-market specialists. Gig marketplaces like Upwork and Fiverr are discussed further down but left out of the table, because they sell you individual freelancers rather than a managed team — the specs aren't comparable.

Callnovo is included because leaving ourselves out of our own comparison would be its own kind of dishonesty. We have flagged the row, and there is a section further down on when we are the wrong choice.

The Three Types of Outsourcing Partners You'll Run Into

Before comparing specific vendors, it helps to know which category they fall into — each is built for a different kind of buyer.

Enterprise BPOs

Large outsourcing firms operating across dozens of countries, built to run support at Fortune 500 scale. Strong on infrastructure and compliance, but minimum contract sizes and onboarding timelines are usually built around six- and seven-figure engagements — a mismatch if you need three to ten agents.

Mid-Market and Boutique Specialists

Smaller outsourcing firms focused on flexible, right-sized engagements — often multilingual, often willing to start with a handful of agents and scale as volume grows. This is the category most fast-growing SMB and e-commerce brands actually shop in.

Gig and Virtual-Assistant Platforms

Marketplaces that match you with individual freelance agents rather than a managed team. Cheapest entry point, but you own the training, quality control, and coverage gaps yourself.

The Six Providers, Side by Side

The "built for" column is our reading of each provider's public positioning, not a published claim. Everything to the left of it is sourced.

Teleperformance (TP)

The largest provider on this list by a wide margin. Its own investor profile claims "nearly 490,000 employees", though third-party datasets compiled from its filings put headcount nearer 446,000, and its FY2025 results announced a restructuring including "workforce adaptation" — a roughly 44,000-person gap between the marketing figure and the filed one, worth knowing before you quote the bigger number back to anyone. Founded in Paris in 1978 and listed on Euronext Paris. Its own website states a presence in "~100 countries" and "400+ languages and dialects."

What that buys you is genuine breadth: if you are launching support in twelve countries simultaneously and need one contract, one compliance posture, and one reporting stack, this is the category that does it. What it costs you is the ability to start small. TP does not publish pricing or a minimum engagement size, and its commercial motion is built around enterprise contracts — a brand asking for four agents is not the customer this machine was designed for.

Foundever

Founded in 1985 as SITEL and headquartered in Luxembourg, Foundever took its current name in March 2023 after the Sitel and Sykes businesses were consolidated. Its own website currently states "130K associates across the globe," "45 delivery countries" and "800+ leading brands". It is privately held, so there are no quarterly filings to read before you sign.

Foundever's public materials describe rightshoring — mixing onshore, nearshore and offshore sites to hit a blended cost — and it publishes "+60 languages supported." What it does not publish is pricing or a minimum engagement size. Practically, it competes for the same enterprise deals as TP.

TaskUs

Founded in 2008, headquartered in New Braunfels, Texas, NASDAQ-listed since June 2021, and ending 2025 with 65,500 teammates. Beyond customer experience it sells content moderation, trust and safety, and AI operations work.

The most useful public fact for a buyer is that TaskUs, alone among the six, files with the SEC — so its client concentration is disclosed rather than guessed at, and its filings show a large share of revenue coming from a small number of very large technology clients. Read the current 10-K yourself rather than trusting a percentage quoted in an article, including this one: the figures move every year. The practical question is whether you would be a rounding error in that mix.

Helpware

Founded in October 2015, Helpware states "19 locations," "11 countries," four continents, "45+" languages and "400+ clients" — with delivery from the US, Mexico, Uganda, the Philippines, Ukraine and Georgia among others. Its pitch is dedicated, client-branded teams rather than pooled agents shared across accounts.

It sits squarely in the mid-market: bigger and more process-heavy than a boutique, far more flexible than TP or Foundever. It publishes neither pricing nor a minimum team size, so both come out of a scoping call.

SupportYourApp

Operating since 2010 and started in Kyiv, SupportYourApp states 1,500+ specialists, support in 60+ languages, PCI DSS Level 1 certification and ISO 27001:2022 compliance, with processes aligned to GDPR, CCPA and HIPAA requirements. For brands handling payment or health data, that certification list is the strongest published security posture among the mid-market providers here.

It is also the only provider on this list that publishes the shape of its engagement tiers rather than hiding them behind a call. Its pricing page lists Essential (0.5–4 talents), Growth (5–19), Enterprise (20–99) and Custom — no dollar figures, but the team-size bands are stated up front, which is more than any other vendor here does.

Callnovo

Callnovo has run multilingual call center operations since 2004, with delivery from Canada, China, Bolivia, Nicaragua and the Philippines, and publishes support in 65+ languages. It sits in the mid-market and boutique category — built for brands that don't yet need, or want, an enterprise-scale contract.

Two things distinguish it operationally. First, engagements start from half a seat, so you can begin with part-time coverage in one language and add capacity as volume actually materialises instead of committing to headcount you are guessing at. Second, support runs through HeroDash, Callnovo's own CRM and contact center platform, which unifies phone, live chat, email and social in one system, with native integrations for Shopify, Amazon and eBay.

When Callnovo is the wrong choice: if you need to stand up support in fifteen countries at once under one master services agreement, or your procurement process requires a publicly listed vendor with audited quarterly filings, the enterprise BPOs above are a better fit than we are.

What None of Them Publish — and What to Ask Instead

Researching this list surfaced something worth naming plainly: five of the six publish no price at all. Teleperformance, Foundever, TaskUs, Helpware and SupportYourApp all route you to a scoping call. Only SupportYourApp publishes its minimum engagement size — and only Callnovo publishes actual rates, which we do on our own pricing page: US$5.80 per hour per dedicated English agent, US$650 a month for a shared English seat covering US business hours, and AI voice packages from US$300 a month. Onboarding timelines and channel coverage are described qualitatively everywhere and quantified nowhere.

That is normal for this industry — real quotes depend on language, hours, channel mix and volume — but it means public research can only get you to a shortlist. The specifics come from the call. These are the five questions that actually separate vendors, and every one of them should be answered in writing:

• Pricing model. Per agent-hour, per contact, per resolution, or a flat monthly retainer? Each shifts risk differently: per-hour puts volume risk on you, per-resolution puts it on the vendor.
• Minimum engagement. Smallest team they will actually staff, and the shortest contract term. Ask what happens if you need to scale down — that answer is more revealing than the scale-up story.
• Time to first live agent. Not "how fast can you onboard" but "what were the actual dates on your last three launches."
• Channels in one system. Whether phone, chat, email and social land in a single platform or in separate tools you stitch together. Ask for a live demo, not a slide.
• Surge handling. What concretely happens if volume triples next month — a product launch, a holiday sale, a viral moment. The answer tells you more about fit for a growth-stage brand than anything on the homepage.

What to Look For in an Outsourcing Partner

Set Clear Goals First

Before evaluating vendors, decide what you actually need to fix — faster response times, lower cost per contact, coverage in a new language, or just more hours of coverage. The right partner depends on the answer: a brand that needs true 24/7 coverage has a different shortlist than one that just needs overflow support during business hours. If you have not yet settled whether to go offshore at all, start with the pros and cons of offshore delivery.

Check Their Track Record

Ask for client references you can actually call, not just logos on a homepage. Ask how long their average client relationship lasts — churn is the clearest signal of whether a vendor delivers past the sales pitch.

Confirm They Can Scale With You

A vendor built for 500-seat programs and a vendor built for 5-seat programs are different businesses wearing similar websites. Match the model to your stage, and ask specifically where you would sit in their client mix.

Get Pricing and Contract Terms in Writing

Understand exactly what you're paying for and what happens if you need to scale down. Vague pricing and long lock-in contracts are two of the most common regrets brands report after choosing an outsourcing partner. Our own pricing structure is documented separately.

What This Looks Like in Practice

Two engagements from our own published case ledger, both with the client's cost outcome on the record:

A UK food-industry SME ran outbound B2B telemarketing to UK Chinese restaurants in Mandarin, six hours a day, six days a week. The client reduced labour costs by 60% versus hiring in London, with a markedly lower turnover rate — and because all calls were recorded, its managers could coach the team remotely.

KyLinTV, a US IPTV and MVNO company serving the overseas Chinese community, moved to 24/7 support in Mandarin, Cantonese and English across the USA, Canada, UK and Australia. The client cut call center cost by 60%, while ARPU and sales close rate rose and average handle time fell.

Most of our case ledger is anonymised — we say so plainly on that page, because client confidentiality is part of the service. KyLinTV is named there with permission.

Frequently Asked Questions

Which call center outsourcing company is best for a small business?

Not the biggest one. Enterprise BPOs like Teleperformance, Foundever and TaskUs are built around large, multi-year programs and do not publish small-team entry points. A small business is better served by the mid-market specialists — Helpware, SupportYourApp or Callnovo — which staff teams in the single digits.

How much does call center outsourcing cost?

Five of the six publish nothing, because real quotes depend on language, hours of coverage, channel mix and volume. The exception is Callnovo, which lists US$5.80 per hour per dedicated English agent and US$650 a month for a shared English seat on its pricing page. For the rest, expect a number only after a scoping call — and insist the pricing model, per agent-hour, per contact or per resolution, is stated in writing before you sign.

What is the minimum number of agents I can outsource?

It varies enormously and is rarely published. SupportYourApp states an entry tier of 0.5–4 specialists; Callnovo takes engagements from half a seat. The enterprise BPOs do not publish a minimum, and their commercial models are built around far larger programs.

Should I choose an onshore, nearshore or offshore call center?

It depends on which cost you are optimising. Offshore delivery (Philippines, India) is cheapest per hour; nearshore (Mexico, Latin America) buys timezone overlap with North America at a middle price; onshore is most expensive and usually reserved for regulated or premium-brand work. Several providers here, Foundever explicitly, blend all three.

How long does it take to launch an outsourced support team?

No provider on this list publishes a standard onboarding timeline. Rather than accept a general claim, ask for the actual signature-to-first-live-agent dates on the vendor's three most recent launches — verifiable history beats a marketing number.

Is it a red flag that a provider won't publish pricing?

No — it is the industry norm. Five of the six providers compared here publish nothing; Callnovo is the exception, listing US$5.80 per hour per dedicated English agent and US$650 a month for a shared seat. The red flag is not the absence of a public rate card but a vendor that will not put the pricing model, the minimum term, and the scale-down terms in writing once you are in a live conversation.

Where to Go From Here

If you are evaluating outsourcing partners for a fast-growing brand, shortlist by category first — enterprise BPO if you need breadth under one contract, mid-market specialist if you need to start small — and only then compare vendors within that category. Comparing TP against a boutique on price is comparing two different products.
