Best Customer Service Outsourcing Companies in 2023

Customer service matters now more than ever. And with ever-evolving circumstances to contend with, brands must rethink best practices and build new strategies to deliver the best service possible. 

When customer service falls short, it can have devastating effects — 86% of consumers have stopped buying from a brand after just one negative experience. But when done right (like through eCommerce customer service outsourcing), your customer service choices can pay dividends — a great experience can drive nearly the same percentage of consumers (80%) to recommend your brand to others. To succeed in today’s competitive landscape, you must take your customer service choices and strategy seriously — which is why choosing the right customer service outsourcing company is critical.

What is customer service outsourcing?

Customer service outsourcing is achieved by going through a quality-driven decision process to access specialists who understand customer service trends, increase customer retention rates and reduce costs.  There are many providers that offer these benefits, however with so many options on the market, narrowing your choices down can be a challenge.

To help, we’ve compiled a comprehensive list of this year’s best customer service outsourcing companies. We’ll provide an overview of the key features that each outsourced customer service company offers, as well as some pros and cons of partnering with each service.

Let’s start with our company. Odondo is a UK-based, outsourced customer service provider with a distributed, pay-as-you-go approach to scalable, omnichannel customer service delivery. We take pride in having re-imagined the traditional outsourced customer service model, providing a quality, flexible and cost-efficient solution.

Service offerings

  • High-quality agents – Because our distributed service model allows for remote working and flexibility, we attract a range of high-quality agents that aren’t restricted by geography or personal circumstances — they’re typically more experienced and educated to a higher degree. We don’t operate a shared service model, so agents work for a single brand and are matched based on their experience.
  • Flexibility – Our clients benefit from unlimited flexibility as they can scale services up and down to match demand. This is particularly useful for businesses that experience seasonal surges — for instance, the eCommerce space during the Christmas period or travel companies during the summer holiday season.
  • Low costs – Odondo’s pay-as-you-go model means no fixed-term contracts and you’ll only ever pay for what you use. The ability to create a bespoke customer service model where you choose which services you use and in what quantities means you can precisely control your budget on a monthly basis. Furthermore, our distributed model means the overheads attached to traditional contact centres don’t apply to us, and as such, these costs are not passed down to you.


  • Quality, UK-based agents available 24/7, who will learn the specifics of your business, with multilingual options available
  • Flexible model, with full control over spending, no fixed-term contracts and the ability to scale resources up or down
  • Will work as a fully outsourced function, or support existing in-house teams
  • Best for medium-sized businesses in areas like eCommerce, but the flexibility and scalability make Odondo a good fit for businesses of all sizes


  • Odondo may not be the best option for companies looking for a one-size-fits-all approach to outsourced customer service, or those seeking agents to provide highly-specialised product support, such as biotech businesses

What is Customer Service Outsourcing?

Customer service outsourcing is achieved by going through a quality-driven decision process to access specialists who understand customer service trends, increase customer retention rates and reduce costs.

Is Customer Service Outsourcing the Same as Offshore Customer Service?

No! Although these terms are often considered interchangeable, they are actually very different. You can have in-house offshore operations and outsourced onshore partnerships.

Fundamentally, customer service outsourcing is about delegating business functions in order to streamline internal operations and take advantage of specialisation and economies of scale.

What Should You Look For in a Customer Service Outsourcing Provider?

Scalability, flexibility, cost-efficiency and high-quality agents.

Is In-house or Outsourcing Customer Service Better for My Business?

Correctly executed, outsourcing provides more benefits than costs with the right partner. However, different types of businesses have more to gain from outsourced customer service partnerships alongside in-house teams.

Odondo has been recognised by DesignRush as one of their Top Call Center Companies
