What is a Call Center?
Call CenterA call center is a centralized operation where trained agents handle inbound or outbound voice calls on behalf of a business. Functions span customer service, technical support, telemarketing, collections, and lead generation. Modern call centers also blend voice with chat, email, and self-service automation to meet customers where they are.
Key takeaways A call center handles phone-led customer interactions, while a contact center adds chat, email, and social channels.
Global contact center spending is forecast to keep climbing as firms layer AI on top of human agents.
The Philippines and India remain the two largest outsourcing destinations, with Manila agents costing roughly 70% less than US equivalents.
Inbound, outbound, automated, and virtual are the four operating models you'll see most often.
Picking the right partner hinges on channel mix, agent quality, security posture, and pricing model — not headcount alone.Outsource Accelerator has tracked the call center sector since 2017, and the shape of the industry has shifted hard. Cloud platforms killed the on-premise PBX. Remote work normalized work-from-home agents, and generative AI now drafts agent responses in real time. The fundamentals still hold though — a voice on the line resolving a customer problem.
The call center label sticks even as the work expands. Most operations that still call themselves call centers actually run blended voice, chat, and email queues out of the same agent desktop. The phone is the anchor channel because it's the one customers reach for when they are frustrated, confused, or spending real money.
How it worksA call center routes incoming or outgoing voice traffic through a telephony platform — typically a cloud contact-center-as-a-service (CCaaS) stack — into a queue and on to an available agent. Workforce management software forecasts call volume. Automatic call distribution (ACD) matches callers to skill groups, and quality assurance teams score calls against rubrics for tone, accuracy, and compliance.
Three layers do the heavy lifting:

CallMiner, Observe.AI, CrestaAccording to Gartner, the contact center market is one of the fastest-growing slices of enterprise software, driven mostly by AI augmentation rather than headcount growth. The agent isn't going away; the tooling around the agent is just getting smarter. Expect copilots that surface knowledge-base answers mid-call, real-time sentiment scoring, and auto-summarized wrap-up notes to be table stakes by 2026.
ExamplesReal call center work looks nothing like the stereotype. A handful of representative operations in 2024:
Concentrix runs more than 440,000 agents across 70 countries, supporting brands like Airbnb and Samsung from delivery centers in Manila, Bogotá, and Cairo. Teleperformance, headquartered in France, posted EUR 8.3 billion in 2023 revenue serving Apple, Uber, and dozens of fintech clients out of Philippine and Indian hubs. TaskUs scaled trust-and-safety and content-moderation lines for Meta, DoorDash, and Netflix from sites in Manila, San Antonio, and Athens. SP Madrid, a mid-market Philippine BPO, runs sub-100-seat campaigns for SaaS and ecommerce clients who can't justify a tier-one provider.The Philippines passed India as the world's largest English-language voice destination around 2011 and hasn't ceded the lead since. The IT and Business Process Association of the Philippines tracks roughly 1.7 million sector workers, with call center agents the single biggest cohort. India still dominates non-voice and tech-support work, while Latin American hubs like Bogotá and Guadalajara grew fast through 2023 on the back of nearshore demand from US clients.
Related termsA call center sits inside a wider cluster of related concepts you'll bump into when scoping a partner:
Contact center: the omnichannel successor that adds chat, email, social, and messaging to voice. BPO: business process outsourcing, the umbrella under which call centers operate. Inbound call center: receives customer-initiated calls for service or support. Outbound call center: places agent-initiated calls for sales, retention, or collections. Customer service: the work category most voice agents are paid to deliver. Telemarketing: outbound sales via phone, a regulated subset of outbound work. Virtual assistant: a one-to-one outsourced role that sometimes overlaps with low-volume support. FAQ What does a call center actually do?A call center handles voice interactions between a business and its customers. Agents take inbound calls for support, billing, or orders, or place outbound calls for sales, surveys, and collections.
Is a call center the same as a contact center?No. Call centers are voice-only or voice-led. Contact centers handle voice plus digital channels (chat, email, SMS, social) through a single agent desktop. Most modern operations are technically contact centers, even when people still call them call centers.
How much does call center outsourcing cost?Pricing varies by geography and model. Philippine agents typically bill at USD 8–15 per hour fully loaded; US onshore runs USD 25–45. Per-minute and per-call pricing remains common for high-volume inbound work.
Will AI replace call center agents?Not entirely, and not soon. According to McKinsey, AI is automating routine queries and assisting human agents on complex calls, shifting the agent role toward higher-value problem solving rather than wiping it out.
Which countries lead in call center outsourcing?The Philippines and India lead in voice volume, followed by South Africa, Colombia, and Egypt for English-language work, plus Poland and Romania for European-language coverage.
How do I pick the right call center partner?Match the provider's vertical experience to your industry, audit their security certifications (PCI DSS, ISO 27001, SOC 2), pilot a small campaign before scaling, and insist on transparent pricing and live agent dashboards.

What is Key Performance Indicator (KPI)?
Key Performance Indicator (KPI)A key performance indicator (KPI) is a quantifiable measure that tracks how well a business, team, or process is hitting a defined goal. KPIs translate strategy into numbers you can review weekly, monthly, or quarterly. Used well, they tell you what's working, what's drifting, and where to spend the next dollar.
KPIs sit one rung above raw metrics. Every KPI is a metric, but not every metric is a KPI. A metric counts something; a KPI ties that count to a target tied to strategy.
Page views are a metric. Page views from buyers in your top three markets, measured against a quarterly target, are a KPI.
According to KPI.org, the discipline's industry body, effective KPIs are "critical, quantifiable measures of progress toward a desired result." That word critical is doing real work. A scorecard with 40 KPIs has no KPIs. Most teams need five to nine.
The term sits at the centre of modern performance management, alongside service-level agreements, balanced scorecards, and OKR frameworks. Each one tries to answer the same question from a different angle: how do you know the strategy is actually working?
How it worksA KPI has four moving parts — the metric, the target, the time window, and the owner. Strip out any one of those and you're back to a vanity number. A revenue KPI isn't "revenue" but "$2.4M new ARR by 31 December, owned by the VP of Sales."
KPIs split along two axes that most operators mix up. Leading indicators predict outcomes. They include pipeline coverage, training hours logged, and sales calls booked.
Lagging indicators confirm them. They include quarterly revenue, churn, and profit margin. A healthy dashboard runs both, because lagging KPIs alone tell you the race is already lost.

VerificationMost teams build KPIs using the SMART framework — specific, measurable, achievable, relevant, and time-bound. The 2025 Bersin "High-Impact People Analytics" research found organisations that tie KPIs to a written strategy are 3.1x more likely to hit financial targets than those running ad-hoc dashboards. The takeaway is brutal: KPIs without strategy are just statistics.
Ownership is the part most decks skip. A KPI nobody owns drifts. A KPI two people own gets argued about, not improved. Assign one name per number, and bake the assignment into the quarterly review cadence.
ExamplesKPIs look different in every department. The shape that matters is the link from one daily number to a quarterly outcome the CEO actually cares about. Here's how that plays out across the four functions most outsourced to BPOs in 2025.
Contact centres lean heavily on first call resolution (FCR), average handle time, customer satisfaction (CSAT), and net promoter score (NPS). ContactBabel's 2024 UK Contact Centre Decision-Makers' Guide put the median FCR for top-quartile centres at 78%, with the bottom quartile below 60%. The 28-second average speed of answer benchmark still holds for inbound voice in 2025, though chat and email carry their own response-time targets.
Finance and accounting teams watch days sales outstanding (DSO), gross margin, operating cash flow, and budget variance. A Manila-based finance and accounting BPO typically reports DSO weekly to the client controller. Concentrix and TaskUs publish quarterly DSO targets for clients inside their managed-services contracts, so the number becomes the contract, not a side report.
Software engineering uses DORA metrics — deployment frequency, lead time for changes, mean time to recovery, and change failure rate. Google's 2024 DORA report ranked deployment frequency as the strongest predictor of organisational performance among 39,000 surveyed engineers. The four DORA KPIs are now standard in BPO dev-ops contracts.
HR teams track employee turnover, time-to-fill, training cost per head, and employee net promoter score. SHRM's 2024 Talent Benchmarking Report pegged voluntary turnover for US white-collar roles at 17.3%, useful context when an outsourcing partner quotes 12% as a competitive number.
Related terms Service level agreement (SLA): the contract that binds KPIs between client and provider. First contact resolution: a flagship contact centre KPI. Average handle time: the productivity KPI for voice operations. Customer retention: the outcome KPI most BPOs are ultimately judged on. Net promoter score: the loyalty KPI most contact centres report monthly. Business process outsourcing: the delivery model KPIs govern. Call centre: where many of the most cited KPIs originated. FAQ What's the difference between a KPI and a metric?Every KPI is a metric, but a metric only becomes a KPI when it's tied to a target, a time window, and an owner. A metric counts. A KPI judges.
How many KPIs should a business track?Five to nine for any single team or executive. Beyond that the dashboard becomes noise and ownership blurs. Pick the few that actually drive decisions, and retire the rest.
What does SMART stand for in KPI design?Specific, measurable, achievable, relevant, and time-bound. The framework forces each KPI to name what's measured, by when, and against what target, which is the four conditions a vague KPI usually fails.
What's a leading versus a lagging KPI?Leading KPIs predict future outcomes — sales calls booked, training hours logged, and pipeline coverage are typical. Lagging KPIs confirm past results, such as quarterly revenue, churn, and profit margin. Run both, or you'll only learn you missed targets after the quarter closes.
How often should KPIs be reviewed?Operational KPIs weekly, departmental KPIs monthly, and strategic KPIs quarterly. Most BPO contracts also bake quarterly business reviews (QBRs) into the SLA so client and provider read the same numbers on the same day.
Can KPIs be qualitative?Yes. Customer sentiment, brand health, and culture surveys all translate qualitative signal into a measurable score. The trick is converting impressions into a number that holds up across reviewers and across time.

What is Order Processing?
What is order processing?Order processing is the sequence of steps that gathers a customer’s data, encodes their order, and passes it on to another department for fulfillment.
Depending on the industry, fulfillment can take the form of shipping or bookings and rentals.
Order processing is a crucial aspect of business processes that involves detailed steps from the moment a customer places an order to the final delivery of the product or service.
Further, depending on the scale of the business, business owners can choose to leverage technology to speed up order processing and use data science techniques to understand their customer base better and predict inventory and sales trends.
Some business owners, however, prefer to use more traditional pen and paper processes for their lower upfront and maintenance costs.
Role of an order processor An order processor is in charge of managing a company’s database platform, responding to customers’ questions and concerns, processing orders, handling payments, and confirming order information before shipment.
In addition, order processors plan the shortest route in Google Maps, ensuring timely delivery and avoiding order delays and customer complaints.
Order processors work closely with delivery drivers and dispatchers to ensure accurate and timely delivery confirmation.
They require computer abilities and strong communication skills, particularly when dealing with consumer criticism of services.
Order processors are integral to the smooth operation of businesses that rely on efficient order processing and inventory management.
Why is order processing important?Order processing is crucial since it leads to more revenue and better customer service. Manual order processing wastes time and money, whereas an efficient order processing system saves time and lowers overheads in the business process.
As soon as you use an order processing system in your business, you’ll be able to scale your business without becoming overwhelmed with customer messaging regarding inquiries and complaints.
By understanding the key steps involved in order processing, businesses can streamline operations, meet customer expectations, and stay ahead of the competition.
From receiving customer orders to delivering the final product, the order processing workflow involves multiple stages that require careful coordination and timely execution.
Choosing the right order processing softwareWhen choosing order processing software for your business, it is important to consider your specific needs and requirements. Here are some factors to take into account:
Features. Make sure the software has the features you need, such as order entry, inventory management, and reporting tools. Integration. Ensure that the software can integrate with your existing systems and tools. Scalability. Choose a software solution that can grow with your business. Cost. Consider the software's cost and weigh it against the potential savings and efficiencies it can provide. Significance of order processing systemsInvesting in an order processing system for your business can have a multitude of benefits. These systems can help reduce order processing times, improve order accuracy, and enhance customer satisfaction.
By automating the order processing process, you can also free up valuable time for your employees to focus on other important tasks.
Order processing systems are vital for a warehouse management system as they optimize the flow of orders through the entire fulfillment process.
Outsourcing order fulfillment processDue to advances in telecommunications technology and cloud-based storage, the order fulfillment process can now be digitized for a considerable price.
Finding the skills to use the data from digital order processing is a much more cost-effective alternative for small business owners because of outsourcing.
Thanks to advances in telecommunications technology and cloud-based storage, order processing can be digitized much more cheaply.
And thanks to outsourcing, finding the expertise to leverage the data from digital order processing is a much more economical option for small business owners.
Efficient order processing is crucial for maintaining customer satisfaction and driving revenue growth.
Outsource Accelerator provides you with access to great order processing specialists. You can outsource from the Philippines starting from $6 per hour, saving up to 70% on staffing costs.
We make it easier for clients to learn about and engage with back-office outsourcing.
Why your business should outsource order processing Outsourcing order processing can be an effective way for businesses to streamline their operations and focus on core activities. The pressure of managing and maintaining an order processing and fulfillment system is eliminated when you outsource order processing.
Many companies are turning to outsourcing as a cost-effective solution to manage order processing needs effectively.
Here are some reasons why businesses need to outsource order processing services:
Help make data-driven decisions When data is distributed across various platforms, it’s difficult to keep track of it. Order processing makes it simpler to assess available data and make data-driven choices by allowing users to access all sales order data in one location.
Since you can see the entire process, order processing makes it easier to recognize real-time issues. Making data-driven decisions can help companies save money for the business.
Further, fixing even the smallest inefficiency may drive supply chain efficiencies and have a big impact on the bottom line when order volume is high.
Saves time and effortWhen you started as an entrepreneur, every hour you spend analyzing fulfillment difficulties is an hour you might be spending on more strategic tasks such as product development or brand growth.
It’s a good start to do everything yourself, but order processing will be a big help to better understand your customer and increase sales.
One advantage of outsourcing order processing is that you won’t have to appoint, train, or deploy customer service and fulfillment employees because the offshore model will take care of everything.
Increase customer satisfactionOutsourcing order processing services can greatly improve customer satisfaction by ensuring orders are processed accurately and efficiently, resulting in timely delivery of products.
This can lead to happier customers and repeat business, as delays or errors in processing can negatively impact your business reputation.
By streamlining the order fulfillment process, businesses can improve customer satisfaction and loyalty.
Cost savingsAnother benefit of outsourcing order processing is cost savings. In-house processing is expensive, requiring investment in technology, staffing, and infrastructure. Outsourcing lets you pay for needed services without overhead costs.
Outsourcing helps avoid errors and delays from in-house processing. Third-party providers process orders quickly and accurately, reducing risks and costs.
Access to specialized expertiseOutsourcing order processing services enables businesses to access specialized professionals who streamline workflows, implement best practices, and enhance efficiency.
Leveraging their skills leads to improved accuracy, faster fulfillment, and increased customer satisfaction.
Further, overcoming personnel and resource attrition, as well as shorter turnaround times and higher efficiency and quality, are benefits of outsourcing order processing.
Scalability and flexibilityOne advantage of outsourcing order processing is its scalability. As your business grows and order volumes change, a third-party provider can adjust its services to meet your needs.
This flexibility helps your business manage peak seasons and high demand without compromising service quality.
Focus on core competenciesBy outsourcing order processing services, your business can focus on core competencies and strategic initiatives, leading to more innovation, growth, and competitive advantage.
Instead of being overwhelmed by daily tasks, your team can prioritize value-added activities for business success. Outsourcing order processing enables you to focus on your core business processes, such as sales, marketing, and product development.
Tips for outsourcing order fulfillment processEnsure effective order management process flow when outsourcing by applying the following:
Define clear objectives. Clearly outline your expectations, including turnaround time, accuracy, and communication frequency. Research potential partners. Investigate multiple fulfillment providers, considering their experience, reputation, and client testimonials. Understand cost structure. Request detailed quotes to understand pricing structures, including fulfillment fees, storage costs, and additional charges. Ensure scalability. Choose a provider capable of scaling your business growth without compromising efficiency or quality. Check technology compatibility. Confirm that your systems (e.g., inventory management and order processing) integrate seamlessly with the provider’s technology. Negotiate contract terms. Negotiate terms that align with your needs, including service level agreements (SLAs), termination clauses, and pricing adjustments. Establish communication channels. Set up regular communication channels to address any concerns, updates, or modifications promptly. Monitor performance. Regularly monitor key performance indicators (KPIs) such as order accuracy, shipping times, and customer satisfaction to ensure the provider meets expectations.What is What is business process outsourcing??
What is business process outsourcing (BPO)?Business process outsourcing (BPO) is the practice of contracting a third-party provider to run a defined business function such as customer support, payroll, accounting, or IT helpdesk. The provider takes ownership of the people, process, and technology, and bills you on a per-seat, per-transaction, or fixed-fee basis.
BPO sits at the intersection of labour arbitrage and operational focus. You hand off a non-core function to a specialist that can run it cheaper, faster, or better, and your in-house team gets to concentrate on what actually moves the business.
The category covers everything from a 4-seat phone team in Cebu answering after-hours calls for a US plumbing firm, to a 5,000-seat captive in Manila handling global claims processing for a Fortune 500 insurer. Same idea, very different scale.
If you've used Apple support, ordered from Amazon, or paid with Wells Fargo, you've talked to a BPO provider — you just didn't know it.
How it worksA BPO engagement runs in three layers: contract, transition, and steady state. You scope the function, sign a service level agreement that locks in response times, quality thresholds, and pricing, then transition the work through documented playbooks and parallel runs before the provider takes the keys.
Pricing usually falls into one of four shapes:
Model
How you pay
Best for Per FTE (seat)
Fixed monthly rate per agent
Steady-volume work like inbound support Per transaction
Set fee per call, ticket, or invoice
Variable-volume back-office tasks Outcome-based
Tied to a KPI like CSAT or collections
Mature processes with clean metrics Hybrid
Base FTE rate plus variable bonus
Long-term partnershipsLocation choice drives most of the savings. Sending work to the Philippines or India (offshoring) typically cuts loaded labour cost by 50–70% versus a US in-house team. Sending it to Mexico or Colombia (nearshoring) trims 30–50% while keeping you in roughly the same timezone. Keeping it domestic (onshoring) protects timezone and language fit but barely moves the cost needle.
The provider absorbs the recruiting, training, real estate, tech stack, and compliance burden. You absorb the vendor-management overhead and the risk that comes with handing a function to an outsider.
ExamplesThe global BPO market hit roughly USD 347.95 billion in 2025 and is projected to grow at a 10.05% CAGR through 2035, according to Precedence Research. That growth is concentrated in a handful of hubs and a handful of named buyers.
Google has used Philippine and Indian BPO partners since 2016 for content moderation, ads review, and customer support — a quiet workforce that scales with each product launch. Meta contracts Accenture and TaskUs in Manila for content moderation; the work pulled enough scrutiny in the early 2020s that Meta eventually broadened its provider base across multiple regions. Wells Fargo has operated a Manila back-office hub since 2011, handling mortgage processing, AML checks, and treasury operations for the US parent. JPMorgan Chase runs large captive and outsourced operations in India and the Philippines for KYC, trade settlement, and analytics.The Philippines remains the standout English-language hub. According to the IT and Business Process Association of the Philippines, the country's IT-BPM sector generates roughly USD 40 billion in revenue and employs about 1.9 million people, with growth targets pushing past 2.5 million by 2028.
Related terms Outsourcing: the umbrella term; BPO is the back-office and front-office slice that runs whole processes rather than one-off projects. Offshoring: moving work to a distant country (e.g. US to Philippines). A location choice, not a contracting choice. Nearshoring: moving work to a nearby country (e.g. US to Mexico) to keep timezone and culture closer. Knowledge process outsourcing: KPO handles judgment-heavy work like legal research or equity analysis, not transactional tasks. Call center: one delivery format inside BPO, focused on inbound or outbound voice. Back office: the non-customer-facing operations layer that BPO most commonly absorbs. Service level agreement: the contract clause that defines what "good" looks like in a BPO deal. FAQ What is business process outsourcing in simple terms?BPO is paying another company to run a piece of your business for you, usually a repeatable function like answering support calls, processing invoices, or managing payroll. You keep the brand and the strategy; they run the operation.
What is the difference between BPO and outsourcing?Outsourcing is the broad category — anything you contract out, including one-off projects. BPO is the subset where a provider runs an ongoing, defined business process end-to-end, typically with its own staff, systems, and SLAs.
Is BPO only about cost savings?No. Cost is the entry argument, but mature buyers cite access to specialist talent, 24/7 coverage, faster scaling, and freeing in-house leaders to focus on growth as bigger long-term wins. See the directory of vetted providers on Clutch for how the market positions itself today.
What functions do companies outsource most often?Customer support, IT helpdesk, finance and accounting, payroll, HR administration, content moderation, and data entry top the list. Higher-judgment work like legal research, equity analysis, and medical coding has shifted to KPO providers over the last decade.
Which countries dominate the BPO industry?The Philippines leads voice and customer experience, India leads IT and analytics, and Latin America (Mexico, Colombia, Costa Rica) leads nearshore work for North American buyers. Eastern Europe serves Western European clients on similar terms.
How do I choose a BPO provider?Match scale to your volume, check for relevant compliance (ISO 27001, HIPAA, PCI DSS, SOC 2), ask for two reference clients in your industry, and pilot a small scope before committing to a multi-year contract. Walk away from any provider that won't share agent attrition data.
