It is 2025. Technology and social media platforms have made reaching potential customers at scale easier than ever. However, you need a great sales team to act on all the leads.
What if you don’t have the resources to recruit, hire, and train a great internal sales team? And what if you don’t need a full internal team year-round?
That’s where outsourced Sales Development Representative (SDR) companies come in!
Not only can outsourcing SDRs save you 70% over hiring an in-house sales rep, but they are often more skilled and experienced, which translates into more leads and conversions!
This article will cover everything you need about outsourcing SDR. Plus, we’ll give you a rundown of the ten best companies so that you can make an informed decision.
To put it simply, outsourcing SDR is when a company hires sales professionals from a third party to conduct sales activities:
Organizations with lower sales budgets can benefit significantly from it. When outsourcing your sales reps, you don’t have to spend time and money on recruiting and training them. You also have the flexibility on team size.
On the other hand, B2B and SaaS companies can find it helpful during a massive growth period. The extra sales reps help to fill their pipeline while the company hires and trains additional in-house reps.

Bandalier facilitates connections between organizations and exceptional individuals residing in a variety of locations around the United States. They focus particularly on small towns and villages, utilizing the often untapped potential of less industrialized areas.
In addition, they recruit, train, and provide high-performing SDRs and customer support teams to assist rising enterprises in scaling even more quickly.
According to Hubspot, the average tenure for an in-house SDR is only 18 months, meaning you’ll need to hire and onboard new sales reps several times a year if you have an in-house team.
Doing this will divert resources and time from other aspects of running your business, as you’ll need to:
Hiring an SDR company will significantly save you time and energy.
Hiring and training costs can quickly add up, especially with the sales industry’s high turnover rate.
Salary and benefits are next. The United States Bureau of Labor Statistics found that employer costs for employee benefits are upwards of 30% of the base salary. This means the total amount you can expect to spend on a single SDR per year is around $100,000.
In contrast, when outsourcing an SDR through a third-party company, the average cost for a single sales rep is $2,490 per month or $30,000 per year. Substantially lower than hiring in-house reps. Let’s also not forget the additional support cost.

In order to understand which outsourcing service is the right one for your business, you need to know what exactly you’re looking for.

A good service will be transparent and give you access to the data/reporting you need to keep track of their progress and the results they’re driving for your business.
Of course, the best kind is the one that meets your needs at the best price.
Outsourcing to an SDR firm is a low-cost option for businesses that don’t have the resources to recruit, hire, and train their own sales reps or don’t need a full sales team all year long.
Moreover, studies have shown that your company can save a lot of money if you hire a reputable service instead of doing it in-house.
So, if you want to grow your business and increase sales, an SDR-as-a-service company might be just what you need!
It is a low-cost choice for businesses that cannot afford high caliber in-house sales reps or do not require an entire sales team year-round. The outsourced SDR company provides sales reps for a fixed price each month and aims to provide you with leads and increased sales. They train their reps and you get access to a team of experienced sales people without having to find and hire them yourself, and without having to take on new employees. This means you can scale up (or down) as quickly and easily as you need to. Read the full guide for more on the advantages of using an outsourced SDR company. The average cost per in-house SDR recruit in 2025 ranged from $6,000 to $10,000, which is rather costly considering that many SDRs are recent college grads who need extensive training and support before being productive. Additionally, they are likely to leave the company within their first year. Outsourcing to an outsourced SDR company is more cost effective and a lot less admin. Check out the full guide for the best outsourced SDR companies to consider. In-house sales reps require a company find, interview, hire and train before they can begin to work. Contrastingly, sales outsourcing, run through a third-party company, are reps hired and managed by a different company, who you engage to do all or some of your sales development. Outsource services focus solely on providing high-quality sales development for their clients, which frees you up to focus on developing your business instead. Frequently Asked Questions
