Call answering is often the first point of contact between your business and a potential customer. But how do you know if it is delivering real value? Measuring the return on investment (ROI) of call handling services isn’t just about counting the number of calls. It is about understanding how those calls translate into leads, conversions, and customer satisfaction.
At Answer My Phone, we work with businesses across the UK to ensure their phone answering service is not just responsive, but measurable too. In this blog, we will explore the key performance indicators (KPIs) that every business should track to evaluate and improve its call handling strategy.
Why Call Handling Metrics Matter
When you invest in a professional call answering service, you want to be sure it is doing more than just answering the phone. You want to know that it is contributing to your growth, improving your customer experience, and supporting your team.
That is where KPIs come in. These measurable figures help you see what is working, identify areas for improvement, and justify your investment.
Key Call Handling KPIs to Track
Here are the most important metrics we recommend keeping an eye on:
Call Answer Rate
This measures how many calls are answered compared to how many are missed. A high answer rate is crucial, especially if you are outsourcing, to ensure every opportunity is captured.
If your business was previously missing calls during meetings or busy periods, you should see a noticeable improvement in this metric once you begin using a call answering service.
First Call Resolution (FCR)
FCR refers to how often a caller’s enquiry is resolved during the first contact. Even if your answering service is not resolving the enquiry directly, passing on accurate information and ensuring the right follow-up can still improve this rate significantly.
Tracking FCR helps you understand how effectively the service is supporting your workflow.
Lead Conversion Rate
This shows how many incoming calls result in a new lead or sale. By tracking this, you can tie the value of your call answering service directly to your revenue.
If conversion rates increase once calls are handled more professionally and consistently, it shows the positive impact of the service on your sales process.
Customer Satisfaction (CSAT)
While this is often measured through surveys or feedback forms, call handling has a direct influence. Customers who speak to someone friendly and professional at first contact are more likely to be satisfied with their experience.
Asking your customers about their initial contact with your business can give you a good insight into how your call answering service is performing.
Speed of Message Delivery
One of the biggest benefits of professional call answering is that messages and details are passed on quickly and accurately. Measuring how fast messages reach the right person can highlight how efficient your current system is.
Fast delivery often means faster responses, which improves customer satisfaction and helps close more business.
Missed Opportunity Rate
This metric looks at how many potential opportunities were lost due to missed calls, slow follow-ups, or incomplete messages. Reducing this number is one of the clearest signs that your call answering service is adding value.
If your missed opportunity rate drops, it means more leads are being captured and more enquiries are being followed up properly.
Response Time
Even if a call is handled by a third party, your internal response time still matters. How quickly you follow up on messages can influence whether a lead converts or a customer stays loyal.
Working with a professional service gives you the ability to follow up faster, with all the key information already in hand.
Setting Benchmarks and Reviewing Regularly
Once you know which KPIs matter most to your business, it is important to set realistic benchmarks. Where are you now? Where do you want to be in six months? Reviewing your call data regularly helps you stay on track and make informed changes.
We can help you with this process, providing insights on how your calls are being handled and what could be improved.
