Measuring Success: KPIs for Evaluating Telesales Outsourcing Performance


Telesales outsourcing is a strategic move for business growth, offering enhanced sales efforts without expanding internal teams. Achieving success requires maintaining a strong client-provider relationship, where communication and trust are key. This is where Key Performance Indicators (KPIs) come into play.

In this article, you’ll learn about the crucial KPIs for monitoring and evaluating your telesales outsourcing performance. By leveraging these insights, you can optimize your efforts, foster a successful partnership, and drive significant business growth. Let’s get started on maximizing the impact of your telesales outsourcing.




Understanding Telesales Campaigns

Telesales outsourcing is a versatile tool that adapts to multiple industries—from telecommunications to healthcare and financial services to consumer products. Each sector tailors its telesales campaigns to meet specific needs, whether cold calling for lead generation in insurance or customer retention calls in the telecom sector.

For instance, a tech company might launch a campaign targeting software renewals, while a health supplements business might focus on upselling products to existing customers. A telecom company might use telesales to introduce existing customers to a new bundle offer to increase user engagement and satisfaction. 

Or a financial services provider could employ an outsourced team to inform customers about a new credit product, using carefully crafted scripts to ensure compliance and convey complex information effectively.

In the B2B sector, these campaigns are often pivotal, focusing on appointment setting to facilitate account openings or to introduce new services to prospective clients. For instance, a software company might use a telesales campaign to set appointments with IT managers to demonstrate the benefits of its latest product suite in a personal presentation.


Industries Leveraging Telesales Outsourcing

Various industries harness the power of telesales outsourcing to achieve different objectives:

  • Telecommunications: Managing customer upgrades and promoting new services.
  • Healthcare: Information dissemination about new medical policies or services.
  • Retail: Launching new product lines or special discount offers.
  • Financial Services: Introducing new banking or investment products.
  • B2B Services: Crucial for industries where relationship-building leads to sales, such as in legal or consulting services, where appointment setting for exploratory meetings can pave the way for substantial contracts.

Importance of Comprehensive Performance Measurement

Focusing solely on the number of monthly sales can lead to the “black box effect,” where the actual workings and challenges of a telesales campaign remain hidden behind the final figures. This narrow focus can obscure vital insights into how campaigns perform and what improvements can be made.

It’s crucial to look beyond the final sales figures to understand the full impact of your telesales efforts. The client and provider need a shared understanding of the campaign goals, target audience, and desired outcomes. This sets the foundation for all subsequent activities and ensures everyone works towards the same purpose.

This comprehensive monitoring supports immediate goals and aligns with long-term business strategies, creating a cheerful and robust partnership between clients and providers.


Elements of a successful relationship with your telesales outsourcer

Comprehensive Training

Outsourcing providers must invest in comprehensive training programs for their agents to ensure success in telesales. These programs should cover:

  • Product Knowledge: Agents must thoroughly understand the client’s products or services to communicate their value effectively.
  • Sales Techniques: Training should include proven sales strategies and techniques tailored to the client’s industry and target market.
  • Communication Skills: Effective communication, including active listening and persuasive speaking, is critical for engaging potential customers.
  • Client’s Tone of Voice: Agents should be trained to adopt a specific tone of voice that aligns with the client’s brand. This ensures consistency in messaging and helps build brand trust and recognition.

Research from Task Drive shows that well-trained salespeople make 57% more sales than their competitors.

Customized Script

A well-crafted script serves as a vital roadmap for the provider’s agents, guiding them through conversations and ensuring consistency in messaging. Typically, the client develops the initial script, incorporating their unique selling propositions (USPs), responses to common objections, frequently asked questions (FAQs), and other critical information.

The outsourcing provider may suggest improvements based on their experience and insights, but changes are implemented only with the client’s agreement. This collaborative approach ensures the script remains true to the company’s brand voice while resonating with the target audience. A well-structured script enhances agent performance and contributes to a revenue growth of approximately 10%.

Targeted Database

A high-quality, accurate database helps the outsourcing team identify potential customers and maximize their outreach efforts. The provider should have the expertise and resources to cleanse and enrich this database and ensure their agents contact the right prospects.

Robust Quality Assurance

The client and provider are responsible for regularly monitoring and evaluating agent performance. This step is crucial to maintaining high standards and identifying areas for improvement. While the provider may handle call recordings and customer feedback surveys, the client can focus on performance metrics analysis.

Transparent Reporting

Providers should create regular, detailed reports on campaign progress, key metrics, and client ROI. This way, the client can prioritize data-driven decision-making and track their performance against established objectives.



Monitoring the performance of telesales outsourcing providers is vital if you want to ensure the success of your outsourcing campaigns. KPIs tell you exactly how the operations are running, where they excel, and where they’re lacking.


Sales Conversion Rates

The Sales Conversion rate measures the number of leads that convert into actual sales. It’s a direct indicator of the effectiveness of the provider’s sales strategies, agent performance, and overall campaign effectiveness. 

Sales Conversion Rate = (# of Conversions / Total # of Leads) x 100

A higher conversion rate indicates more efficient and effective sales tactics. However, it’s important to consider industry benchmarks for a fair assessment. For example, if a telesales team makes 1,000 calls and secures 100 sales, the Sales Conversion Rate would be 10%. If the industry average is 5%, the team’s performance can be considered superior.

A low conversion rate necessitates a review of several aspects:

  • Database Quality: Ensure the database is recent, accurate and the contacts have not been overused.
  • Sales Script Effectiveness: Revisit the sales script to ensure it resonates well with the target audience.
  • Agent Training: Assess if the sales team needs further training to improve their negotiation and persuasion skills.

Quality of Leads Generated

High-quality leads are more likely to convert, which leads to higher revenue and ROI. Measuring this KPI is tricky, as you’ll need to track factors like lead accuracy, relevance to your target audience, and level of interest in your products or services.  

Lead Quality Rate = (# of Qualified Leads / Total # of Leads) x 100

To use this formula, you must define what a “qualified” lead means for your business, considering factors like lead source, engagement level, budget, authority, need, and timeline (BANT).

Higher scores indicate better lead quality. A low score suggests taking action to improve the qualification process, such as:

  • Enhancing Lead Sourcing Methods: Look into more effective lead generation sources.
  • Tightening Qualification Criteria: Refine the criteria used to qualify leads before handing them to the sales team.
  • Feedback Loop: Implement a feedback loop from the sales team to the lead generation team to continuously improve lead quality.


Customer Feedback and Satisfaction

Customer feedback gives you deeper insights into the quality of the provider’s customer service, agent professionalism, and overall customer experience. You can collect feedback through surveys, ratings, or direct interactions to gauge customer satisfaction and identify areas where the provider can improve.

Average Handling Time (AHT)

This KPI measures the average duration of your customer interactions. In this case, lower isn’t always better – it’s essential to strive for efficiency but not more than ensuring your customers meet their needs.  

AHT = (Total Talk Time + Total Hold Time + Total After Call Work Time) / Total # of Calls Handled

The ideal AHT varies by industry and campaign objective. However, a higher-than-desired AHT may suggest:

  • Streamlining Call Processes: Identify and eliminate unnecessary call elements.
  • Enhanced Agent Training: Focus on training agents to handle calls more efficiently without compromising quality.
  • Technological Support: Implement better call management tools to aid quicker resolution of customer issues.



As your partnership with the outsourced telesales team matures, it becomes increasingly important to evaluate its strategic impact. Certain advanced KPIs can give you deeper insights into your client-provider relationship’s overall value and long-term viability.


Return on Investment (ROI)

This fundamental KPI measures the financial return generated by the outsourcing investment. Monitoring ROI shows how financially effective the partnership is and where costs and returns can be optimized.

ROI = (Net Profit / Costs Incurred) x 100

The costs incurred include provider fees, technology expenses, and other associated costs.


Churn Rate of End Customers

This KPI measures the number of customers who stop doing business with your company over a specific period. Churn reflects the provider’s ability to acquire and retain customers. A high churn rate could indicate an ineffective sales approach and low quality. 

Churn Rate = (# of Customers Lost / Total # at Start of Period) x 100

The “period” would be the duration you’ve worked with the telesales outsourcing team.


Provider’s Employee Turnover Rate

High employee turnover within the provider’s team isn’t good for their service consistency, quality, and overall performance. It can also lead to knowledge gaps, training challenges, and decreased morale. 

Employee Turnover Rate = (# of Employees Who Left / Average # of Employees) x 100

If your provider’s employee turnover rate is rapidly increasing, it may be due to poor working conditions or low compensation, inadequate training and support, or a toxic work environment. Communicate with your provider about the reason for the turnover and how to improve it. 



Now that you know the “what,” it’s time to focus on the “how.” Let’s see how to implement and track the aforementioned KPIs. Here’s what you should know.


Setting Up KPIs With Your Outsourcing Provider

The client and the provider need to track these metrics for the most accurate analysis. These best practices will help you set KPIs with your outsourcing provider more efficiently.

  • Our list of KPIs is simply a guide, not a hard and fast formula. You can work with your provider to define KPIs that align with your unique company goals. For instance, if customer acquisition is a priority, focus on KPIs like sales conversion rates, cost per acquisition, and customer lifetime value.
  • SMART goals guarantee success. Ensure your KPIs are Specific, Measurable, Achievable, Relevant, and Time-Bound. This gives your outsourcing team something to strive for and a deadline to reach those goals.
  • Establish baseline data for each KPI before the campaign starts. This will be a benchmark for measuring progress and identifying trends over time.


Effective Monitoring and Regular Performance Reviews

The next step is continually monitoring your defined KPIs and exchanging regular performance reviews with your outsourced team for deeper analysis. Here are some techniques on how to do so effectively:

  1. Use a centralized dashboard to track KPIs in real-time. This way, both parties have the same visual representation of the performance, making it easier to identify trends and outliers.
  2. Schedule regular meetings with your outsourcing provider to discuss KPI performance (at least once per month, but weekly is usually a better frequency, as it allows you to detect performance issues almost on the spot and immediately take action). This is also an opportunity to address concerns, celebrate successes, and maintain open communication.
  3. If a KPI falls below expectations, conduct a thorough root cause analysis to find out why. This will guarantee that you’re only spending resources on relevant efforts. 
  4. Develop action plans to address the performance gaps or issues identified during your reviews. These plans should include specific actions, timelines, and responsibilities to ensure accountability.

Strengthening the Outsourcing Partnership With Data-Driven Insights

Finally, you must keep nurturing and strengthening your outsourcing partnership. That doesn’t just mean maintaining clear communication and aligning your goals and using data-driven insights to find out what needs fixing. Here are some tips to consider:

  • Your KPI data won’t just benefit customers – you can also use it to identify opportunities for continuous improvement in your and your provider’s processes. That may involve improving the scripts, training programs, or targeting strategies.
  • You can also use your KPI data to collaborate with your provider on problem-solving. Fostering a culture of shared responsibility, accountability, and mutual commitment will bring you a step closer to achieving shared goals.
  • To ensure your outsourced team is truly committed to your success, you can even offer performance-based incentives in your contract with the provider. This will motivate them to achieve or exceed KPI targets and align their interests with yours.



As with any business partnership, you may not always see eye to eye with your telesales outsourcing team. Don’t let this sour your client-provider relationship – address all performance issues proactively to maintain productivity. 


Identifying Underperformance

Early detection is key to effectively resolving performance issues. Look for red flags like declining sales conversion rates, increased customer complaints, and missed SLAs. These could indicate decreased service quality, operational inefficiencies, and staffing shortages.


Collaborative Problem-Solving

Open communication is key to addressing performance issues head-on. Work with your provider to analyze the call recordings, agent performance data, and customer surveys to determine the root cause of the performance decline. Then, create SMART action plans to address the cause. 


Continuous Improvement Framework

No matter how effective your outsourcing strategy may seem, there’s always room for improvement. Implementing continuous improvement techniques in your sales processes can lead to a 32% increase in sales and a 37% boost in profit margins.

Encourage honest and frequent feedback from both sides and, more importantly, make sure your strategies are flexible and scalable. You never know when your customer needs, business goals, or market factors may change.



Telesales outsourcing success isn’t just about hitting sales targets. It’s also about nurturing a strong client-provider partnership with data-driven insights. The right KPIs will guide both parties toward a more effective telesales strategy and a stronger relationship.
