      B2B Review from Greg Digneo

      Best decision we made last year was partnering with this CX team for our customer support, billing, and sales assistance. We were drowning in client emails and chasing invoices late at night instead of focusing on SEO strategy. Results have been incredible: client response times dropped from hours to under an hour, payment collection improved 60%, landing page conversions up 28%, and client retention increased 35%. They integrated seamlessly with our systems and scaled with us as we grew. Now we have more time to focus on delivering SEO results instead of being stuck in support tickets all day. If you're an agency juggling client support with campaign management, this team is a game-changer.

      Email Marketing Review from Josh Kaye

      I recently engaged Cience Lead Generation, paying $10,000 for 250 qualified leads, expecting a professional service and solid prospects. Unfortunately, what I received was far from that. The leads they presented were completely fabricatednone of the individuals or businesses had requested information about my company. In fact, we obtained sworn affidavits from many of these so-called "leads" affirming they had never heard of us or requested any information.This is a blatant scam, and we're now in the process of pursuing legal action against Cience to recover our full payment. If you are considering working with them for lead generation, I strongly urge you to reconsider. Their practices are fraudulent, and you risk losing a significant amount of money without getting anything of value in return. We were misled, and now we're facing the consequences of trusting this company. Dont make the same mistake.

Frequently Asked Questions

What is an inbound call center company?

An inbound call center company is a company that specializes in handling incoming phone calls from a business’ customers. It offers an experienced team of agents who can elevate a company’s customer service by efficiently resolving inquiries, addressing concerns, and offering helpful support regarding product and service issues. 

Inbound call centers cater to customer support; not to be confused with outbound call centers which focus more on increasing sales and generating leads. Inbound call center services can be categorized depending on service model and location, namely: 

By service model: 

  • In-house call center: The inbound call center company owns and operates its facility. It has no direct control over its client’s staffing, training, and technology. 
  • Virtual inbound call center: These centers use a remote workforce, with agents in different locations, often working from home or in dedicated co-working spaces. This offers more flexibility and access to a broader talent pool. 
  • Outsourced call center: The company outsources its operations to a third-party provider specializing in inbound call center management. This can be cost-effective but requires careful selection. 
  • Blended call center: Agents handle inbound calls for multiple clients, especially if their accounts have low or inconsistent call volume. 

By location: 

  • Onshore call centers: Located in the same country as the company they serve, offering cultural understanding and easier time zone management but typically at a higher cost. 
  • Offshore call centers: Located in a different country, often with lower labor costs. However, there might be potential language barriers, cultural differences, and time zone challenges. 

The demand for hiring quality customer support increases, as the global call center outsourcing market is predicted to reach $172.77 million in 2030, with inbound call center services taking the majority of it. This need is further emphasized by the limited resources of the dominating contributor of the business sector in the US — small businesses. 

Moreover, customer support is an external representation of a business’ core values. An effective inbound call center company can increase sales and brand trust. One example of this is the case study of BloomNation, a platform for floral companies, who wanted to deploy effective customer support with the help of Peak Support

Peak Support offered experienced agents who will provide tech support for florists. From troubleshooting to editing links and product listings, agents communicated with the client’s engineering team to address and fix flagged issues. Their tasks also included handling customer inquiries while embodying the brand voice to ensure a positive customer experience. 

BloomNation’s partnership with Peak Support contributed to exceptional results, such as: 

  • Client retention rate of 97% 
  • Full resolution time of 11.6 hours 
  • 86% customer satisfaction (CSAT) rate 
  • First reply time of 5.5 hours 
  • Revenue churn of .66% 

What does an inbound call center company do?

An inbound call center company specializes in handling incoming phone calls from customers or clients on behalf of a business organization. They act as the front line for businesses, providing various services including, but not limited to, customer support, account management, sales support, and order processing. The primary functions and activities of an inbound call center company include: 

  • Customer support: Address customer inquiries, troubleshoot problems, and answer questions about products or services. 
  • Technical support: Diagnose technical issues, guide customers through troubleshooting steps, or escalate complex issues to specialists. 
  • Order processing: Agents can take orders over the phone, process payments, and answer questions about products or deliveries. 
  • Sales support: Handle inbound sales inquiries, qualify leads, and potentially close deals over the phone. 
  • Account management: Help customers with account-related issues like managing subscriptions, updating information, or processing returns. 

The case study of Sight Partners, a pioneer in clinical and surgical practice, is one example of a successfully implemented inbound call center service. Due to its growing market, the client reached out to ProtelBPO so it could address the gaps in its fragmented customer lines. The client’s industry is also a challenge, requiring niche knowledge of insurance, revenue, authorizations, and copay practices. 

ProtelBPO knew that the client’s industry needed expert agents who could handle sensitive customer information to maintain brand trust. It provided the client with a dedicated team per service area that could simultaneously respond to different customer inquiries. Guided by experienced managers, agents could cater to the client and its customers’ needs with reduced training time. 

Sight Partners experienced significant growth throughout the partnership, such as: 

  • Achieved an average wait time of 90 seconds 
  • Established an FAQ area to improve efficiency and customer support 
  • Continuous in-depth training to improve agent response to complex customer questions 

How much do inbound call center services cost?

Inbound call center services cost $26 to $30 per hour in the US. However, this price can vary depending on factors such as location, agent expertise, niche, facilities, and certification requirements. 

Inbound call center services are typically priced in two structures

  • Per minute: This is ideal for low volume or inconsistent call flow. Clients pay based on the length of each call, including talk time and after-call wrap-up. In this pay structure, agents are usually a part of blended model where they work for multiple accounts. Costs can range from $0.90 to $1.35 per minute. 
  • Per hour: This model suits businesses with high call volume and requires dedicated agents. Hourly rates typically range from $30 to $40 per hour. 

On the other hand, nearshore and offshore inbound call center services also differ in pricing depending on their location: 

Type of call center Price per hour 
Nearshore  $13 to $23
Offshore$8 to $14 

On DesignRush, the top 50 inbound call center companies charge an average of $36 per hour. Roughly 42% of inbound call center services on DesignRush accept projects with a minimum budget of less than $1,000, while 1% require a $50,000+ minimum budget. 

Why should I hire an inbound call center company?

You should hire an inbound call center company to leverage and boost your support services. These specialists offer expertise in streamlining and elevating your company’s consumer interactions, resulting in happier customers. Moreover, improved customer experience has also increased sales revenues by up to 7% and profitability by 2%, according to McKinsey research

Furthermore, the budget for in-house call center can range from $50,000 to $60,000 per agent, without the additional costs for facilities, training, and management. This shows that hiring an inbound call center agency is more cost-effective than onboarding an in-house team. 

Hiring inbound call center services can benefit your business in many ways, namely: 

  • Expertise and professionalism: Inbound call center agents are typically well-versed in the products or services offered by the company they represent. They can also quickly adapt to the product, service, or account assigned to them. 
  • Faster conflict resolution: Inbound call centers staffed by trained professionals can boast higher first-call resolution rates, by addressing customer issues on the initial contact. According to industry benchmarks, the standard of first-call resolution rates of inbound call center companies is 70% or higher. Hiring an effective company translates to less customer frustration and increased brand trust. 
  • Cost-effectiveness: Setting up and running your own call center can be expensive, especially when you factor in infrastructure, technology, and employee salaries. Inbound call center companies can provide these services at a lower cost since you can control the budget as needed. 
  • Scalability: Inbound call centers can easily scale their operations up or down to meet your needs. This is especially helpful for growing companies experiencing seasonal fluctuations in call volume. 
  • 24/7 support: If you have a global customer base, you may need to offer support around the clock. Inbound call centers can staff agents in different time zones to ensure customers can always reach someone for help. 
  • Streamlining business operations: Hiring an inbound call center service can free up your internal staff to focus on other tasks and ensure that your customers get the help they need in a timely and professional manner. 

One prime example of the efficiencies brought by hiring customer support is the case study of a leading consumer operated and oriented (CO-OP) health plan and insurance company. The client contacted Fusion CX to accommodate the increase in customer inquiries during its open enrollment period. 

Fusion CX addressed the support staffing challenge by assessing the client’s goals. Then, the team crafted a customized solution to manage all call activities generated throughout the enrollment period. To ensure success, Fusion CX provided a project management team with seasoned healthcare executives. This team possessed a deep understanding of the client's business objectives, particularly the importance of delivering exceptional customer service. Fusion CX also built a customer support team who underwent formal training on the client's specific health plans and business processes. 

As a result of the collaboration, the client achieved the following results: 

  • Significantly reduced wait times by directing new member calls to specialized agents, ensuring a smoother experience. 
  • Surpassed target for new memberships, adding over 72,000 new members to its health plan during the open enrollment period. 
  • The dedicated staffing model provided flexibility, improved customer experience management (CXM), and reduced expenses. 

How do I choose the best inbound call center company for my business?

To choose the best inbound call center company for your business, follow these steps: 

  1. Identify your call center needs: The first step to finding the perfect inbound call center partner is understanding your own business needs. Analyze your call volume to determine the level of support required. 
  2. List your needed services: Prepare a list of inbound call center services you need. Identify the types of customer support they will handle, whether it’s technical support, order processing, or general inquiries. 
  3. Define your budget: A defined budget helps you target affordable options with features you need, negotiate better deals, and set realistic expectations for service levels. Consider both initial and ongoing costs to build a sustainable partnership with the inbound call center company you will choose. 
  4. Find potential partners: Leverage online directories like DesignRush to find inbound call center companies. Filter options based on your specific requirements, team size, and budget. 
  5. Know its industry experience: Explore your possible partner’s website to learn about its inbound call center services. Look into its expertise, case studies with similar businesses, pricing models, and customer support. 
  6. Request for client reference and portfolio: Request for a company portfolio and ask for client reference based on their completed projects. Contact their previous clients and gather insights from their experiences and the partnership’s results. 
  7. Consider location: Location plays a crucial role in choosing an inbound call center company. See what time zone they operate in and know about their availability to offer customer support. Labor costs can also vary depending on location. International call centers, particularly in developing countries, may offer lower operational costs compared to Europe and America. 
  8. Look into language proficiency: The agents’ English proficiency is a factor, especially if most of your customers are Americans. However, if you have a global customer base, hiring an inbound call center company in specific regions can offer a deeper understanding of local customs and communication styles. 
  9. Factor-in client testimonials: Get a bigger picture of how the inbound call center company works by reviewing previous clients’ experience on platforms like DesignRush or Google My Business. These platforms offer comprehensive reviews of a company’s inbound call center services. 
  10. Shortlist candidates: Narrow your options for inbound call center companies and reach out to express your interest in working with them. 
  11. Send a request for proposal: Send them a request for proposal (RFP) and ask for a project breakdown, including milestones, scope, schedule, costs, and other desired deliverables. 
  12. Assess the agents’ expertise: Assess the qualifications and experience of the agents and support staff assigned to your account. Check if the agents possess relevant expertise to minimize the need for extensive training on your specific products, services, or industry. 
  13. Ask about security measures: Ensure they hold relevant certifications for data security and quality management. 
  14. Make a choice: Review contracts and select the inbound call center company that best suits your goals, budget, and requirements. 

You can also detail your project requirements and budget and send it to us at DesignRush Marketplace. We will choose the inbound call center agencies we estimate are a good fit based on your requirements and send you the list of our top companies. Then you can interview them and find the ideal candidate for the project.

If you have a limited budget, agencies like VoiceNation, AnswerConnect, and Call Management Resources accept projects requiring a minimal budget of below $1,000.

What are the key success metrics used by inbound call center companies?

Inbound call center companies implement key success metrics to measure different aspects of the project, such as customer satisfaction, agent performance, and operational efficiency. The following benchmarks serve as the basis for the project’s success: 

Customer satisfaction: 

  • CSAT (Customer Satisfaction) scores: A direct measure of customer satisfaction after an interaction. Customers are typically asked to rate their experience on a scale. High CSAT scores indicate satisfied customers.  
  • QA (Quality Assurance) scores: Scores assigned by internal evaluators who assess agent call handling based on pre-defined criteria such as following protocols, communication skills, and problem-solving. It also measures agent adherence to best practices. 
  • Net Promoter Score® (NPS®): Measures customer loyalty by asking how likely they are to recommend the company to others on a scale from 0-10. High NPS scores indicate promoters who will advocate for your brand. 
  • Customer effort score (CES): Measures how easy it was for the customer to resolve their issue during the call. Lower CES scores indicate a smoother experience for the customer. 
  • First contact resolution (FCR): The percentage of calls where the customer’s issue is resolved on the first contact, eliminating the need for follow-up calls. A high FCR indicates efficient problem-solving by agents. 

Agent performance: 

  • Average speed of answer (ASA): The average time it takes for a call to be answered by a live agent. Lower ASA translates to shorter wait times and improved customer experience. 
  • Average talk time: The average time an agent spends speaking directly with the customer during a call. 
  • Wrap-up time: The time an agent spends after a call to document the interaction and update any necessary systems. 
  • Missed and declined calls: The number of calls that were either unanswered or actively rejected by an agent. 
  • Total resolution time: The total time it takes to resolve a customer's issue, including hold time, talk time, and any transfers. 
  • Agent utilization rate: Measures the percentage of an agent’s time spent on calls and call-related activities compared to their total work time. 
  • Calls answered per hour: The number of calls an agent answers within an hour. 
  • Average handle time (AHT): Indicates the average time it takes to handle a call from start to finish. While a lower AHT might seem ideal, inbound call center companies should also ensure that customers receive quality solutions or resolutions during their calls. 
  • Call availability: The percentage of time agents are logged in and available to take calls. 
  • Call quality monitoring: Involves reviewing recorded calls to assess agent’s adherence to scripts, communication skills, and ability to resolve issues. This helps identify areas for improvement in agent training and coaching. 

Operational efficiency: 

  • Calls handled: The total number of calls the call center received and handled during a specific period. 
  • Cost per call (CPC): The total cost of handling a call, including agent time, overhead, and technology costs. 
  • Call arrival rate: The rate at which calls are received by the call center. Helps predict staffing needs and identify peak periods. 
  • Peak-hour traffic: The time of day or week with the highest volume of inbound calls. 
  • Average age of query: Average length of time unresolved queries stay open if not resolved on the first attempt. It reflects how long issues wait for resolution. A high average age of query indicates inefficiency in addressing customer problems. 
  • Callback messaging: This refers to the functionality offered by some call centers to notify customers via text message or other digital channels when an agent becomes available to return their call. It helps improve customer experience by eliminating the need to stay on hold. 
  • Repeat call rate: This metric tracks the percentage of calls where a customer contacts the call center again for the same or a related issue within a specific timeframe. High repeat call rates indicate problems with FCR or inadequate issue resolution. 
  • Percentage of calls blocked: This metric calculates the number of inbound callers that receive a busy tone due to the lack of available agents or software limitations. 

What questions should I ask inbound call center companies before hiring one?

Before hiring an inbound call center company, ask these questions to assess if it can accommodate your client’s needs and ensure customer satisfaction: 

Its Relevant Background 

  1. Do your agents have experience in handling the same account as ours? 
  2. How do you train your agents to handle customers? 
  3. What services do you offer beyond call handling? 
  4. What is your average client retention rate? 
  5. Can you provide case studies showcasing client partnerships? 
  6. Do you offer language proficiency testing to ensure agents can effectively communicate with our diverse customer base? 

Its Services and Processes 

  1. What call center software and technology do you use? 
  2. What are your processes for handling customer inquiries, complaints, and escalations? 
  3. How do you track agent performance and satisfaction?
