    What is an Outsourced SDR?

    To put it simply, an outsourced SDR company is a cost effective option for companies that either do not have the resources to establish a great team of in-house sales representatives or do not need an entire team year-round.

    Usually, a business will hire a third-party SDR company, which handles a group of sales development representatives. This team of SDRs can range anywhere from a single representative to a team of five or more. The size of the team depends entirely on the company’s needs and budget.

    Organizations with lower sales budgets can benefit significantly from SDR outsourcing companies. When outsourcing your sales reps, you don’t have to spend time and money on finding the right person or training them. The third-party company handles all that for you!

    On the other hand, B2B and SaaS companies can find it helpful to hire an outsourced SDR company during a massive growth period. The extra outsourced sales reps help to fill their pipeline while the company hires and trains additional in-house reps.

    Summary: What is an Outsourced SDR?

    Outsourced SDRs (sales development representatives) are a low-cost option for companies that can either not afford in-house sales representatives or do not need an entire team year-round.

    Outsourced SDRs vs. In-House SDRs

    If you’re unsure if your company needs to hire in-house or outsourced SDRs, there are a few key differences and factors that you’ll need to keep in mind.

    Time

    The first thing to consider is the time you’ll spend hiring and training in-house SDRs, and salary a skilled and experienced candidate will require vs. outsourcing them.

    According to Hubspot, the average tenure for an in-house SDR is only 18 months, meaning you’ll need to hire new sales reps several times a year.

    Doing this will divert resources and time from other aspects of running your business, as you’ll need to:

    • Spend vast amounts of time posting about your vacant position on job boards and websites
    • Interview dozens of applicants
    • Train your sales reps

    Contrastingly, when you hire an outsourced SDR company, they handle all of that for you. All you need to do is find the right company.

    Infographic of Differences between outsourced SDRs and in-house SDRs

    Cost

    Each time you hire a new sales rep, you have to spend money training them to ensure they actually add value. If you don’t, your company will suffer in the long run. And with SDRs moving on from companies so quickly, the cost can quickly add up.

    Just the salary for a single sales rep can add up to $63,135 per year. That’s not even accounting for the average cost of hiring each sales rep ($6,000-$10,000) or the costs associated with training them (up to $6,000  per year).

    Then there are the benefits. The United States Bureau of Labor Statistics found that employer costs for employee benefits are upwards of 30% of the base salary. In an SDRs case, this equals around $19,000 a year.

    This means that 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.

    If you want to learn more about the difference, check out this video by SalesNash.

    Summary: Outsourced SDRs vs. In-House SDRs

    Outsourced SDRs are sales reps who are contracted out from a third-party company. Contrastingly, in-house SDRs are sales reps who you have to find, interview, hire and train yourself. Therefore, outsourced SDRs are almost always more cost-effective than in-house SDRs.

    Who Manages Outsourced SDRs?

    Unlike when working with in-house SDRs, when you outsource your sales development representatives to a third-party company, they handle everything.

    Infographic of 10 Reasons to Get an Outsourced Team
    Source: AI bees

    Outsourced SDR companies help make sure that you don’t have to:

    • Spend hours posting on job boards.
    • Interview barely-qualified candidates.
    • Do any onboarding.
    • Train SDRs.
    • Micro-manage sales reps.
    • Settle for the level of skills and experience you can afford (if you’re tight on budget).

    The outsourced SDR company will handle all of that for you!

    And, what’s more, their whole business is to sell for you so they will most likely provide their sales team with the relevant resources and technology. They’ll take all the pressure off you and your company, letting you do what you do best; create a brilliant product or service.

    It’s important to note that someone from your company will need to manage the outsourced SDR company in terms of setting goals, monitoring their progress and making sure they are reaching those goals. 

    Summary: Who Manages the Outsourced SDR?

    The third-party outsourcing SDR company will manage every aspect of the sales reps, from onboarding and training to results and resource management.

    How to Choose the Right Outsourced SDR Company and How to Measure Them

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

    The size, budget, and goals of your company are all deeply important when it comes to choosing a third-party sales rep company.

    infographic of Break down of costs associated with outsourced SDRs vs. in-house SDRs
    Source: SalesBread

    But, once you’ve got all that figured out, there are other factors that need to be considered before you hire an SDR company:

    • What are their prices compared to other SDR companies?
    • What do they promise (in terms of turnover and communication)?
    • How extensive are their services?
    • How do they track progress?
    • Do they offer several packages to meet their client’s needs?

    Moreover, the specific services the outsourced SDR company offers and how their progress will be tracked are also very important and should be carefully considered. Ways to track and measure an outsourced SDR company include targets for:

    • The number of emails sent per week/month
    • Open rates
    • Reply rates
    • Call screening
    • Sales
    • Their conversion rate for every step in the funnel

    A good outsourced SDR company 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 SDR company for you is the one that meets your needs at the best price. But some companies are just better than others.

    Below, we’ll take a look at the best SDR companies and what they offer to help you find the perfect one for your business.

    Summary: How to Choose the Right Outsource SDR Company

    When choosing an outsourced SDR company, you must consider your business’s size, budget, and goals. Once you have those in mind, you can look at the SDR company’s packages, prices, progress metrics, and communication strategy to choose the best one for your company.

    Conclusion

    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 SDR outsourcing company instead of hiring sales reps to work in-house.

    So, if you want to grow your business and make more money, an SDR as a service company might be just what you need!

    Frequently Asked Questions

    What is an Outsourced SDR?

    An outsourced SDR firm 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.

    How much does it cost to hire an in-house SDR?

    The average cost per in-house SDR recruit in 2024 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.

    What is the difference between outsourced SDRs and in-house SDRs?

    In-house SDRs are sales reps that you as a company need to find, interview, hire and train before they can begin to work. Contrastingly, outsourced SDRs, run through a third-party company, are sales reps hired and managed by a different company, who you engage to do all or some of your sales development. Outsourced SDRs are companies that focus solely on providing high-quality sales development for their clients, which frees you up to focus on developing your business instead. Read the full guide to learn more about the pros and cons of in-house vs outsourced SDRs.
