Call Center Outsourcing: The Complete Guide to Doing It Right

Customer experience (CX) has always been just as important as the products or services you sell. And in today’s overly saturated market, where even a single bad interaction is enough for 63% of consumers to switch to a different brand, the stakes have never been higher.

This puts additional pressure on in-house teams, which are probably already swamped with core revenue-generating tasks. Add CX to their responsibilities, and you’ve got yourself a recipe for slow response times and mediocre service quality.

That’s precisely why more and more businesses are choosing to outsource call center services. By delegating customer communication, or at least a part of this workload, to specialized agents, organizations can improve service quality and minimize costs.

However, call center outsourcing only works when tailored to your specific business needs. Fortunately, this guide will dive into outsourcing models, costs, benefits, and drawbacks, and show you the right approach so you can determine whether outsourcing is right for you.

What Is Call Center Outsourcing?

Simply put, call center outsourcing refers to delegating phone-based customer interactions to specialized third-party providers. It allows businesses to provide round-the-clock availability and top-tier service quality while also reducing fixed staffing costs and improving scalability.

Call center outsourcing shouldn’t be confused with contact center outsourcing. The latter is a much broader term that encompasses email, chat, and social media, as well as the voice-based interactions that call centers focus on.

How Call Center Outsourcing Works (End-to-End)

Before you go reviewing call center outsourcing companies and their models, costs, and agents, there are a few things you’ll need to do on your end to ensure a successful operation.

It all starts with defining your specific business needs. That means you should know from the get-go the channels you want to support, the hours you want to cover, the volume of interactions you expect, and the types of issues agents will deal with.

Once you have that figured out, it’s time to start with knowledge transfer and agent training. In practice, that involves your in-house teams documenting your product or service details, policies, and escalation rules for the provider’s agents to soak in.

Up next is the tech stack. At this point, third-party agents get connected to your customer relationship management (CRM) software, as well as helpdesk and phone systems. The goal here is to enable logging, tracking, and reports in the same tools that your teams already use.

With that settled, you’re ready to roll out with a pilot. This essentially involves a small group of agents handling a portion of your regular customer interactions to help you gain insights into real-world performance. You can then ramp up outsourcing to a level you’re satisfied with.

From here on out, call center outsourcing becomes pure maintenance. That means supervisors providing ongoing coaching and conducting quality assurance (QA) checks based on reporting to ensure performance aligns with your business goals.

Call Center Outsourcing Models (Choose the Right Fit)

There’s no one-size-fits-all solution when it comes to call center outsourcing. That’s why modern providers like ShyftOff essentially let you build your own model, which boils down to choosing based on:

Call Direction

• Inbound: Some businesses choose to outsource inbound calls, such as customer inquiries and troubleshooting.
  
  • Best for: Customer support and helpdesk tasks
  • Advantage: Drastically improves response times
  • Disadvantage: Requires extensive product knowledge
• Outbound: Others delegate outbound services, such as sales or customer surveys.
  
  • Best for: Structured outbound efforts
  • Advantage: Large-scale campaign execution
  • Disadvantage: Premium costs for outbound experts

Team Structure

• Shared teams: Although more affordable than dedicated teams, these agents support multiple businesses simultaneously, which can have drawbacks.
  
  • Best for: Businesses outsourcing basic tasks
  • Advantage: Reduced costs
  • Disadvantage: Potential impact on average speed of answer (ASA)
• Dedicated teams: These agents focus exclusively on your business, but also cost more than shared teams.
  
  • Best for: Businesses that want consistency and control
  • Advantage: Agents focused solely on you
  • Disadvantage: Drastically higher costs compared to shared agents

Geography

• Onshore: Same-country agents (onshore) offer the strongest cultural alignment.
  
  • Best for: Situations where understanding is key
  • Advantage: Native speakers who know the culture
  • Disadvantage: High costs
• Nearshore: Agents from nearby regions (nearshore) are cheaper than onshore agents but still provide an almost perfect understanding of the local context.
  
  • Best for: Balance between understanding, availability, and price
  • Advantage: More affordable than onshore
  • Disadvantage: Potential collaboration issues
• Offshore: This approach offers the greatest cost savings, but agents from other countries (offshore) may not have the best language skills.
  
  • Best for: Businesses on a budget
  • Advantage: Low cost
  • Disadvantage: Potential language barriers

Scope

• Full outsourcing: When you choose to outsource call center services, you can go all-out and delegate all inbound and outbound calls to third-party providers.
  
  • Best for: Companies seeking a fully hands-off solution
  • Advantage: Drastically reduced internal staffing costs
  • Disadvantage: Limited oversight
• Hybrid: You can also outsource only a subset of your operations while retaining the rest in-house, especially if they’re high-value or complex tasks.
  
  • Best for: Businesses that want flexibility and control over interactions
  • Advantage: Perfect pair of internal expertise and selective scaling
  • Disadvantage: Challenging management workflows

What You Can Outsource

Speaking of options, the great thing about call center outsourcing is that you can choose the exact tasks you delegate. Here are a few examples:

• Customer support: Most businesses choose to outsource Tier 1 support inquiries. Many also use call center outsourcing services for after-hours requests and overflow calls, especially during renewal seasons.
• Technical support: Beyond general inquiries, outsourced agents can also handle basic technical issues and ticket categorization to free up your in-house specialists.
• Sales and outbound campaigns: Some companies also outsource outreach, with third-party teams contacting leads and handling basic upsell efforts. This ensures your in-house sales experts can focus on high-intent conversations.
• Surveys and market research: Customer feedback is another area where outsourced agents can shine. These teams are often tasked with running structured programs and collecting responses to uncover market trends.
• Lead qualification and appointment setting: Third-party agents are also regularly used in the early stages of a typical sales funnel. Here, they handle lead assessment and scheduling, with your in-house team taking over to pursue high-value prospects.

Benefits of Call Center Outsourcing

When done right, call center outsourcing brings various advantages to the table for both inbound and outbound assistance:

• Cost control and reduced overhead: Businesses can save on office, licensing, and training-related expenses, as well as fixed staffing costs, and enjoy a far more predictable cost model.
• Extended coverage and faster scaling: Outsourcing makes it far easier to provide round-the-clock service in multiple languages. It also enables quick ramp-up of support during both expected seasonal demand and unexpected volume spikes.
• Speed-to-answer improvements: With dedicated agents often logged into multiple queues, your customers will spend far less time waiting. This can directly impact your customer satisfaction (CSAT) scores.
• Trained agents and specialization: Many call center outsourcing companies invest heavily in specialized agents, so taking the outsourcing route gives you access to that talent across various industries, such as trained nurses for healthcare services.
• Better reporting and visibility: With a well-integrated tech stack, outsourced systems can provide valuable performance insights. Meanwhile, clear dashboards make it easier to analyze calls, spot issues, and jump in if necessary.

Risks and Downsides (And How to Prevent Them)

As you can imagine, it’s not all rainbows and sunshine here, and you can certainly hit a few walls when you outsource call center services:

• Loss of product knowledge: Third-party agents rarely understand your products as well as internal teams do, which can lead to script reading rather than genuine help. That said, detailed documentation and proper onboarding can help close that gap.
• Inconsistent tone and brand experience: Due to the sheer volume of the talent pool, an outsourcing partner can sometimes struggle to maintain CX consistency. However, brand playbooks and regular reviews can ensure that interactions don’t drift apart.
• Data security and compliance gaps: Both inbound and outbound calls can involve sensitive customer information, which not all providers keep as safe as you do. That’s why reviewing data policies and compliance certifications is a must.
• Hidden costs: While outsourcing is often cheaper, costs can creep up, especially if internal teams regularly step in to fix third-party agent errors. Fortunately, it’s also preventable if you limit the scope and define ownership from the get-go.
• KPI trade-offs: Many call center outsourcing companies push agents to answer calls as quickly as possible, which can lead to rushed conversations and frustrated customers, even if metrics look fine. To avoid such situations, you’ll need to track CSAT scores and repeat contact alongside response times.

Call Center Outsourcing Costs (What Actually Drives Pricing)

If you’re ready to outsource call center services, it’s helpful to understand how providers calculate their fees first. Most offer the following pricing models:

• Per-agent
• Per-minute
• Per-contract
• Per-ticket
• Per-productive hour

While the first four models are pretty self-explanatory, Per-productive hour pricing does stand out. Offered by modern call center outsourcing companies like ShyftOff, where you only pay for productive time, the time agents are in queue, on phones, or completing after-call work, making it quite flexible and ensuring that you’re only paying for what you need at the moment.

Beyond the base framework, the total cost of call center outsourcing also depends on other operational factors. That includes channel coverage, working hours, language needs, customer interaction complexity, training depth, and tech stack requirements.

And as you can imagine, going with the cheapest call center outsourcing services rarely delivers the best results. Providers in this bracket often cut corners, which can impact CX and cost you business in the long run. You’ll be far better off with a less affordable but more value-focused outsourcing partner that invests in training and consistency.

How to Choose a Call Center Outsourcing Partner (Scorecard)

Speaking of outsourcing partners, selecting one isn’t always the most straightforward task. That’s precisely where a structured evaluation system with weighted criteria (from least important (1) to most important (5)) like the one below comes in handy. It can help you find an outsourcing provider that perfectly aligns with your specific business needs:

• Industry and domain experience (5): Look for outsourcing companies with relevant industry backing and a deep understanding of your particular niche.
• Hiring and training rigor (4): Assess how the potential partner vets and trains agents to represent different brand voices.
• QA and performance oversight (4): Ensure there’s a robust system with strong monitoring features and well-designed feedback loops in place.
• Reporting transparency (3): Check if there’s real-time access to key performance indicators (KPIs) without filters.
• Security and compliance posture (5): Pay attention to the provider’s data handling practices, access controls, and compliance certifications, such as SOC 2 or HIPAA.
• Scalability and surge capacity (5): Evaluate the ability to quickly ramp up support during both expected and unexpected volume spikes.
• Tool stack and integrations (3): Confirm that the provider’s system can integrate with your existing tools, including your CRM, helpdesk software, or preferred contact center as a service (CCaaS) platform.
• Commercial terms and flexibility (2): Look for providers with transparent pricing models that can match your current and future business needs.
• Case studies and references (1): Lastly, validate the potential partner’s claims by digging through success stories and contacting their existing clients.

Best Practices for Managing an Outsourced Call Center

Once you’ve chosen a call center outsourcing partner, the focus shifts to clear communication and proactive management so third-party agents can become a true extension of your business. Here are a few tips that can help:

• Implement a robust tech stack to ensure customer data can flow smoothly between your CRM and the provider’s platform.
• Have your in-house teams document your company’s workflows and keep knowledge bases up to date so outsourced agents are always aware of policy changes and can provide the same service quality your internal support does.
• Assign supervisors to monitor and coach third-party agent interactions and regularly conduct performance evaluations.
• Outsource call center tasks that are repetitive and keep high-stakes situations in-house or establish clear escalation paths if you go the full outsourcing route.

Final Thoughts

In a market where even a single bad customer interaction can lead to lost business, service quality really shouldn’t be an afterthought. Unfortunately, that’s precisely what it is for most already stretched-out internal teams.

Call center outsourcing offers a way to regain that control, but only when it’s approached with clear goals, as well as with a model and a partner that align with your specific business needs.
