Why Hire Call Centers for Your Company?

The global pandemic has significantly decreased the importance of outside sales and boosted online interactions, so B2B call centers have come into the limelight. 

Did you know that approximately 15 million people currently work at call centers all over the world? This number is rapidly growing, so there will be even more workplaces in this industry, as stated by the call center statistics. 

In general, the total revenue of all existing call centers is $200 Billion, and this number is expected to double by 2022. 

There might be different reasons why your company might need the services that call centers can provide.

  1. First, inbound call centers help their clients deal with a growing volume of incoming calls and free up the phone line that might be otherwise overloaded.
  2. Second, you might want your team to have more time to focus on more important tasks, such as personalizing emails and making targeting more accurate. 
  3. Third, you may want your services to be accessible 24/7. Indeed, in this case, the support team will help your prospects and clients immediately resolve any issue. Such an approach will significantly improve their conversions and repeat sales and also positively contribute to your company’s reputation. 
Hire a call center to handle incoming calls, free up your team’s time, and make your services available 24/7.

What Criteria Determine Good Call Centers? Investigate Their Services and Technologies

Various companies might look similar, but when you start digging deeper, you will see that not all of them are equally good. Thus, it’s essential to find the right agency for your business to seamlessly get leads and not lose them once you begin your cooperation. 

We’ve prepared a set of criteria to help you distinguish between a plethora of agencies and find out which one will bring you the best results. 

  • Types of Services

First of all, it's important to find out whether the agency delivers inbound or outbound services

Inbound services include dealing with the incoming calls on behalf of your organization, as well as processing orders, dispatching, delivering help desk services, managing appointments, and answering the requests in a live chat.

As for outbound services, they are usually associated with different lead generation efforts. For instance, such companies can process survey information or make cold calls to get you new clients. Outbound experts can also send follow-ups and ensure powerful lead nurturing. 

Some agencies offer tips on how to enhance communication with potential and existing customers and improve your retention rates. 

Once you have discovered the company that matches your business needs, try to also get to know whether the level of services complies with your expectations. The fact is, the new support team will represent your company, so it's very important to be sure that they will do it professionally.

Additionally, find out whether the company provides monolingual or multilingual services.

If your company operates in a single region, there’s no point in paying extra for the multilingual support. But if you have an international business, it is of primary importance to have a variety of representatives who speak foreign languages. 

Thus, be sure to know exactly which languages the agency supports and whether they can provide translation services (and if they come at an additional cost or are included in a package.) 

  • Location

Sometimes it is enough to use a local company, especially if your business is bound to a specific region. However, you may also consider hiring a nationwide or an offshore agency. Here are the differences between them.  

Any domestic company will ensure a seamless customer experience due to native English speakers and the latest technological solutions. At the same time, an offshore agency can deliver services of lower quality but cost considerably less. Thus, your choice will depend on your needs — not every business requires a support team speaking impeccable English.

  • Price

Depending on the company’s status and the range of options it provides, agencies will have completely different pricing policies. Select the services to meet your business needs and feel free to refuse from the ones you don’t need. Your investments will pay off if you find the company to fulfill your specific requests.

  • Security Technology

Make sure that the company you’re going to work with will protect your privacy. The fact is, the agency’s experts will be likely to request the information about your business. It will include sales scripts, customer data, detailed reports on your users’ behaviour and various issues that you’ve come across recently. 

As you can see, this data is sensitive, so the agency of your choice should guarantee that there will be no data breaches. Trust only proven companies that use advanced technology and have a good reputation on review platforms — don’t hesitate to monitor the feedback its clients give.

Consider types of services, location, price, and security while choosing a call center.
