Seventy-seven percent of salespeople report working more hours now than before the pandemic, and 74% spend most of their workday on non-sales activities. Selling has also become tougher — 89% of buyers want to be challenged by sellers who can change their way of thinking. All this makes sales leaders now wear multiple hats — prequalification, sales calls, and B2B outreach are just some areas that need attention.

With the pressure of meeting sales targets, unstable economic conditions, and a shortage of high-quality sales reps, crucial sales activities are bound to get overlooked. That’s where outsourced B2B sales come in.

Sales team outsourcing enables sales leaders to tap into third-party experience across multiple industries. This results in access to new markets, increased accountability when meeting sales goals, a laser focus on the sales funnel, and, ultimately, lower costs.

In this article, we’ve gathered the best B2B sales outsourcing companies and what you need to know before outsourcing.

What makes a great B2B sales outsourcing company

It’s possible for a company to specialize in just B2B sales outsourcing or to offer it under the umbrella of other services. Remember, sales itself is a broad field. Researching, prospecting, qualifying, nurturing, closing deals, and maintaining customer relationships are all part of the process.

While it takes a sales rep an average number of 8 touches to generate a desired conversation, this may very well vary by industry, buyer persona, and product. Given these factors, here are 5 non-negotiables you should look for when outsourcing B2B sales.

Industry expertise

The right B2B outsourcing company must have industry knowledge, specific skill sets, and access to the right resources. The buyer personas for every company are different, but relevant industry experience gives sales teams an idea of what their prospects expect. It also saves time when you don’t have to get the team up to speed on market trends and best practices.

Proven track record

The modern customer trusts reviews regardless of whether they’re in the B2B or B2C domain. For B2B companies, a proven track record exists in logos from past customers and case studies. Belkins’ case studies page, for example, highlights a range of clients who experienced specific challenges and solved them with Belkins’ help.

You can also research further and reach out to these clients to get firsthand feedback. Ask questions about engagement, problem resolution, customer support, and overall satisfaction.

Sales process

What’s the workflow process? How flexible is it? What methods do they use to track progress and prioritize tasks? Is there an analytics component?

Complete visibility into what’s happening behind the scenes gives you the freedom to plan, adjust tactics, and measure KPIs. For example, if past experiences show you July and August are slow months for sales due to the summer holidays, give your input and shift resources to other high-value activities.

Dedicated experts

Many marketing and sales service providers offer complementary services, and that’s all right. It allows you to scale up or down without switching vendors. What matters, though, is whether it involves multiple dedicated teams or 1 team managing multiple clients.

The latter’s a problem because you need experts who understand even the most complex problems. It may also be an issue if multiple teams report to the same person, who may be spread too thin to handle the demand.

Tech stack

Prospecting, nurturing, appointment generation in B2B — the list goes on. Each of these activities requires different tools, and it’s essential to select a vendor with an integrated tech stack that minimizes system-hopping so you can access customer data across platforms. Data security and ownership, too, should be non-negotiables here.

Data-driven methodology

Although data-driven methodologies are the foundation of sales processes, some vendors may not have the resources or systems to measure and address customer touchpoints. Keep an eye out for best practices like customer segmentation, lead scoring, and personalized messaging that deliver tangible results. You should also look for a vendor who can provide weekly or monthly reports on progress, sales trends, and customer feedback.

What is included in outsourcing costs?

Outsourcing costs vary depending on the project, the service provider, and other factors. Generally speaking, they may include setup fees (usually one-time payments) and ongoing monthly/annual rates. Depending on the project, additional fees may be required for services like data collection or legal advice. It’s critical to discuss all costs and payment terms with the vendor before starting a project.

Why do companies outsource to agencies when they have the resources in-house?

Outsourcing to a specialized agency allows businesses to access expertise not available in-house. It also helps them scale quickly, save time and money by tapping into the vendor’s existing resources, and redirect internal resources to focus on core objectives like deal closing.

What are the benefits of partnering with an outsourced sales team?

These include access to a larger talent pool, faster onboarding, reduced operational costs, improved customer service and engagement, better scalability and flexibility, and increased ROI.
