10 Best Outsourced Customer Service Providers for 2025
Compared to recruiting and managing an in-house customer service team, outsourced customer service is the most time and cost-effective, and resource-efficient way to manage customer service at scale.
This is important because customers who receive poor service will go elsewhere. According to Forrester Research: 63% of customers will walk away from a company following just one bad experience.
On the other hand, 71% of people will recommend a company to friends and family, and on social media if they receive high-quality service.
Outsourced customer service is a huge industry, currently worth over $100B and likely to grow to over $132B through 2028. With so many providers in this industry, it can be confusing knowing if you're going to pick the right one.
To make this easier, we have compiled a list of the top 10 outsourced customer service vendors, reviewed and updated from 2024's list for 2025, including their pros and cons, and more information about them.
What is Outsourced Customer Service?
Outsourced customer service is an operational model for outsourcing your customer service provisions to a third-party provider. Instead of recruiting and managing an in-house team, an outsourced agency can handle all of your customer-centric communications.
Pros of Outsourced Customer Service
There are several advantages to customer service outsourcing, including:
- A wide range of services, including telephony/voice support, email, live chat support, and in-app support (including in some cases via Amazon and other platforms)
- More cost and time-effective than having all of those staff on payroll
- A better quality of service
- More flexible: scaled up or down customer service provisions as needed
- Customer service in safe hands: entrust your customer service to providers that already manage this for huge global brands
Cons of Outsourced Customer Service
Before going this route, there are a few disadvantages to customer service outsourcing. There are also other things to be aware of as it will involve contracts, allocating budgets, etc.:
- A business's reputation is entrusted to a third party. The outsourced provider will be speaking on your behalf, so you need to train the staff who train customer service agents
- You need to have internal resources and communications with other teams ready to handle customer service issues via a third party. So that if an issue needs escalating, agents can pass these along to in-house team members
- Self-help and self-serve solutions and software ready to support inbound customer service tickets will help keep outsourcing costs down
- Be clear on costs and potential ways budgets could over-run and the potential flexibility in the event of customer requests increasing suddenly
- Be clear on lag time before scaling up or down customer service provisions so you can adequately plan ahead
