Quick Answer: Choose a contact centre outsourcing partner in three stages: pass/fail checks on security, compliance and capacity; a weighted scorecard that puts customer outcomes ahead of hourly rate; and a paid pilot that proves the claims before you sign for scale. Price matters, but the cheapest quote is often the most expensive programme. Site Selection Group’s 2026 research found that once attrition, time zone management, quality and compliance are counted, the gap between well-run nearshore and offshore operations is often $2 to $4 an hour or less.
Key Takeaways
- Buy outcomes, not hours. Score providers on customer outcomes, security, total cost, workforce, technology, resilience, governance and references, in that order of weight.
- Regulators expect real diligence: the FTC’s Safeguards Rule requires firms to select service providers able to maintain safeguards, put security expectations in the contract and reassess them periodically (FTC).
- UK financial firms stay fully responsible for outsourced functions and must be able to exit without harming service continuity (FCA SYSC 8).
- 2026 fully loaded rates run $8 to $14 an hour in the Philippines with 60% to 80% attrition, against $10 to $16 in South and East Africa with 20% to 35% attrition (Site Selection Group).
- Benchmark before you sign: US contact centres averaged 99 seconds to answer, 8.9% abandonment and 76% first-call resolution (ContactBabel).
- A paid pilot of 6 to 8 weeks is the single best test of any provider’s promises.
Call Centre vs Contact Centre: What You Are Actually Buying
A call centre handles phone calls only. A contact centre handles voice plus email, chat, messaging and social from one platform, so each agent sees the customer’s full history whatever channel they used. Decide which you need first, because the technology, staffing and pricing all follow from your channel mix.
Most contact centres still handle much of their volume by voice, then add digital channels, self-service and AI on top. The practical test for a buyer is whether the provider runs those channels from one integrated platform with a shared customer record, or from separate systems that make customers repeat themselves. If you want the background first, our explainer on what a BPO call centre is covers the definitions.
Once you know what you are buying, the next step is deciding how you will judge the people selling it.
A Three-Stage Decision Rule
The most reliable way to choose a partner is to separate the decision into three stages and never let a strength in one stage compensate for a failure in another. A great price cannot rescue a provider that fails your security checks.
- Pass/fail gates. Legal and regulatory requirements, security evidence, financial stability, the hours and languages you need, and the delivery locations you will accept. Any provider that fails a gate is out.
- Weighted evaluation. Score the remaining providers on a scorecard, with price as one weighted line rather than the deciding factor.
- Proof. Reference calls without the provider present, a site visit to the actual floor that will serve you, and a paid pilot on real work.
This structure also gives you a clear audit trail for procurement and leadership, which matters when the cheapest bidder does not win.
What Regulators Expect From Your Due Diligence
Even if your sector is not regulated, the rules that apply to banks, insurers and data controllers make an excellent checklist, because they describe what good oversight of a third party looks like. The common thread is that you can outsource the work but not the responsibility.
In the US, the FTC’s Safeguards Rule tells covered businesses to select service providers with the skills and experience to maintain appropriate safeguards, spell out security expectations in the contract, build in ways to monitor the provider’s work and reassess its suitability periodically (FTC). NIST’s supply chain guidance, SP 800-161 Rev. 1, adds that supplier risk should be assessed and managed across the whole relationship, from selection through monitoring, incident response and exit (NIST).
In the UK, a data controller remains responsible for its processors, so you need a written processing contract that covers security, sub-processors, audits and the return or deletion of data at the end (ICO). FCA-regulated firms go further: under SYSC 8 they remain fully responsible for outsourced functions and must be able to end the arrangement without detriment to the continuity and quality of service to clients (FCA Handbook). The FCA’s operational resilience work also expects firms to test third-party disruption scenarios against their impact tolerances (FCA).
These rules translate directly into the scorecard below.
The Selection Scorecard: What to Score and How to Weight It
Apply this scorecard only to providers that pass your gates. Score each criterion from 0 to 5, multiply by the weight and add the results. The weights below are a recommended starting point, not an industry average, so adjust them to your programme.
| Criterion | Weight | Evidence to request | Red flag |
|---|---|---|---|
| Customer outcomes and quality | 22% | 12 months of FCR, CSAT, QA and complaint data for comparable programmes | Only company-wide averages, no definitions |
| Security, privacy and compliance | 20% | ISO 27001 certificate and scope, SOC 2 report, PCI DSS AOC, incident history | Logos without reports, or a certificate that excludes your site |
| Total cost of ownership | 16% | Rate card, staffing ratios, shrinkage, setup, technology and indexation charges | Price well below what wages and staffing can support |
| Workforce capability | 12% | Named leaders, attrition by site and tenure, training and nesting plan | “Team assigned after signature” |
| Technology and integration | 10% | Platform, CRM integration, QA and workforce tools, data export | You cannot get your own raw data |
| Scalability and resilience | 8% | Hiring capacity, seat capacity, tested continuity plan | Backup site that has never been tested |
| Governance and transparency | 7% | Sample monthly report, escalation model, improvement process | Sales team cannot introduce the operations lead |
| References and fit | 5% | Three comparable clients, including one recent launch | Only unrelated or tightly scripted references |
Score price fairly by comparing each bidder’s total cost to the lowest compliant total cost, not to the lowest headline rate. A quote that leaves out management, technology or the hours you need should never set the benchmark. That brings us to the question every buyer asks.
Is the Cheapest Contact Centre Quote the Best Value?
Usually not. The right comparison is cost per satisfactory resolution, not cost per scheduled agent hour, because a cheaper hour that produces more repeat contacts, more supervision and constant retraining quickly costs more overall.
| Location | Fully loaded rate (2026) | Annual attrition (est.) |
|---|---|---|
| US onshore | $25 to $42 an hour | 25% to 40% |
| Mexico and Central America | $11 to $20 an hour | 30% to 50% |
| Philippines | $8 to $14 an hour | 60% to 80% |
| India | $6 to $12 an hour | 50% to 70% |
| South and East Africa | $10 to $16 an hour | 20% to 35% |

South Africa usually costs more per hour than the Philippines or India. Here is what the difference buys. Lower attrition means agents stay long enough to master your product, so you pay for training once rather than repeatedly. South African contact centers report 25% annual attrition, below the US at 30%, and resolve 86% of calls at first contact, ahead of the UK at 81% and the US at 76% (ContactBabel). Every call resolved first time is a repeat call you do not pay for. And South Africa’s UTC+2 time zone covers the whole UK working day without night shifts.
A simple illustration: a $9 hourly rate is about 31% below a $13 rate. It stops being cheaper if rework, extra supervision, replacement training and service failures add more than 31% to the true cost. Our guides to the true cost of offshore customer service and offshore call center attrition rates show how to model this, and the call centre outsourcing cost guide breaks down per-hour and per-FTE pricing.
The KPI Benchmarks That Matter
Hold a provider to a small set of clearly defined metrics: service level, speed of answer, abandonment, first contact resolution, CSAT, quality score and agent attrition. Use published benchmarks to set realistic targets, but remember that a market average may be too low to accept as your SLA.
| KPI | US average | UK average | South Africa average |
|---|---|---|---|
| Average speed of answer | 99 seconds | 116 seconds | 27 seconds |
| Call abandonment | 8.9% | 5.9% | 4.2% |
| First contact resolution | 76% | 81% | 86% |
| Agent attrition (annual) | 30% | 21% | 25% |
Sources: ContactBabel US guide; ContactBabel South Africa guide 2025-26.
The common service level convention is 80% of calls answered within 20 seconds. Whatever targets you set, define each one precisely in the contract: the exact numerator and denominator, the system of record, whether results are measured per interval or averaged monthly, what is excluded, and your right to see raw interaction-level data. For first contact resolution, check repeat contacts in your own CRM over an agreed window rather than relying on the provider’s figure. Our guide to BPO contracts and SLAs covers the wording.
Security Evidence to Request
Certificates prove less than most buyers assume, so ask for the full documents and check their scope. The question is never “are you certified?” but “does the certificate cover the legal entity, site, people and systems that will handle my customers?”
- ISO 27001: the certificate, its scope statement and the Statement of Applicability. Confirm the delivery site and any remote agents are in scope, and verify the certificate with the named certification body.
- SOC 2 Type II: the full report, not a summary. Check the period covered, the criteria included and any exceptions.
- PCI DSS: the signed Attestation of Compliance for the service you are buying, plus a responsibility matrix. A “PCI compliant” claim on a website is not evidence.
- Privacy law map: how the provider meets UK GDPR, POPIA for South African delivery, and any US state privacy laws or HIPAA that apply to your data.
- Technical assurance: a recent penetration test summary, multi-factor authentication, privileged access controls and call recording controls.
Our guide to evaluating a partner’s data security and compliance goes into each in more depth. With the paperwork checked, the remaining work is to test the provider in practice.
Running the Process: RFP, References and a Paid Pilot
A well-run selection takes roughly 14 to 24 weeks from RFP to first go-live, depending on integrations and volumes. That time is cheap compared with a failed transition, and most of it overlaps with work you need to do anyway.
The RFP. Share 12 months of interval-level demand, your contact reasons, channels, hours, languages, systems, security requirements, KPI definitions and a standard pricing template with every permitted fee. Without a common template, quotes are not comparable.
References. Ask for clients that match your delivery country, channel, size and complexity, and speak to them without the provider present. Useful questions: what was promised and what was delivered, how long stabilisation took, which charges were a surprise, and whether they have renewed or expanded. Our checklist on verifying an offshore provider’s references has more.
Site visit. Visit the floor that will actually serve you, not a showcase site. Check access control, clean-desk rules, wallboards, QA calibration sessions, training rooms and backup power, and meet the leaders named in the proposal.
Paid pilot. Run 6 to 8 weeks on representative work, with entry criteria, success thresholds and conversion terms agreed in advance. A pilot should prove hiring speed, training quality, integration, KPI trajectory, reporting transparency and security controls. Training quality is often the hidden variable, which is why we cover BPO agent training quality separately.
Red Flags and How to De-Risk the Decision
Most failed outsourcing relationships show warning signs during selection. Treat each of these as a reason to dig deeper or walk away.
- A price well below comparable bids. Ask for a wage-to-rate breakdown that shows management, shrinkage, training and technology.
- No named operational team. Make interviews with the proposed leaders a condition of award.
- No attrition or early-tenure data. Request attrition by site, programme and tenure, and check it against payroll records.
- Reluctance to run a paid pilot. A confident provider wants to prove itself on your work.
- Company-wide KPI averages only. Strong accounts can hide weak queues, so ask for programme-level data.
- No access to your raw data. You need event-level exports to audit performance and to leave if you have to.
- Exit terms left until after award. Agree the exit plan, data return and transition rates before you sign.
Contract terms are your final safeguard: meaningful service credits, termination rights for chronic SLA failure or a security breach, prior approval of any sub-contractor, audit rights, and a maintained exit plan.
Why UK and US Brands Choose South Africa
South Africa combines strong spoken English, a working day that matches the UK, and service outcomes that outperform both UK and US averages, at a cost well below onshore delivery. That makes it a natural fit for complex, voice-led and brand-sensitive programmes.
South Africa scored 602 on the EF English Proficiency Index 2025, ranking 13th in the world, and is one of only three countries rated “High” for spoken English (EF EPI 2025). Its business services sector created 26,346 international jobs in 2025 (ITWeb). South Africa runs on UTC+2 all year, one hour ahead of the UK in summer and two in winter, so a normal South African shift covers the full UK day.

Frequently Asked Questions
What is the difference between a call centre and a contact centre? A call centre handles telephone calls only. A contact centre handles voice plus email, chat, messaging and social from one platform, so agents see the customer’s full history across channels. The practical test is whether channels share one customer record or sit in separate systems.
How do you choose a contact centre outsourcing partner? Use three stages. First, pass/fail checks on security, compliance, capacity and locations. Second, a weighted scorecard that puts customer outcomes ahead of price. Third, matched reference calls, a site visit and a paid pilot on real work before committing to scale.
What should a contact centre RFP include? Include 12 months of interval-level demand, contact reasons, channels, hours, languages, systems and integrations, security requirements, precise KPI definitions and a standard pricing template that lists every permitted fee. A common template is the only way to make quotes comparable.
Is the cheapest contact centre quote the best value? Usually not. Compare cost per satisfactory resolution rather than cost per agent hour. Higher attrition, repeat contacts and extra supervision can wipe out a lower rate. Site Selection Group found the true gap between well-run nearshore and offshore operations is often $2 to $4 an hour or less.
What KPIs should a contact centre partner be measured on? Measure service level, average speed of answer, abandonment, first contact resolution, CSAT, quality score and agent attrition. US contact centres average 99 seconds to answer, 8.9% abandonment and 76% first-call resolution, so set targets above those averages and define each one precisely.
What security evidence should a contact centre provider show? Ask for the ISO 27001 certificate with its scope, a SOC 2 Type II report, a signed PCI DSS Attestation of Compliance for the service you are buying, a privacy law map and a recent penetration test summary. Check that each document covers the site and team that will serve you.
How long does it take to select and launch a contact centre partner? Allow roughly 14 to 24 weeks from RFP to first go-live, including a 6 to 8 week pilot. With Afrishore BPO, a dedicated team is typically live in 4 to 6 weeks once the contract is signed.
Why do UK and US companies choose South Africa for contact centres? South Africa offers strong spoken English, a UTC+2 time zone that covers the full UK day, and strong service results: 86% first contact resolution and 27-second average answer times. Annual agent attrition of 25% also keeps programme knowledge in the team.
Afrishore BPO runs dedicated, omnichannel contact centre teams from South Africa for UK and US brands, measured against contractual SLAs on service level, first contact resolution and CSAT. Explore our full range of business process outsourcing services.
