How to outsource B2B sales 

Selecting a B2B sales partner on a whim will cause you to burn cash and resources and lose revenue. To avoid such an outcome, here are 10 questions to ask when outsourcing B2B sales to a vendor.

Do they have industry expertise?

The right B2B outsourcing company must have industry knowledge, specific skill sets, and access to the right resources. The buyer personas for companies differ, 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.

Do they provide value for money?

Before you commit to an outsourcing company, confirm that they provide value for money. You can evaluate this by reading lots of the company’s reviews. If the company has reviews on platforms like Capterra, it makes the process easier. Why? Customers rate the value for money they get from vendors. For instance, Belkins has a rating of 4.9/5 in the Value for Money category on Capterra.

Belkins Value for Money Rating on Capterra


Do they have a proven track record?

For B2B companies, a proven track record exists in logos from past customers and case studies. Belkins’ 60+ case studies highlight a range of clients who experienced specific challenges and solved them with Belkins’ help.

You can also research further and contact these clients for firsthand feedback. Ask questions about engagement, problem resolution, customer support, and overall satisfaction.

Does their outsourcing model fit your company?

The outsourcing model of your preferred vendor has to fit into your company's goals. Here’s how they look:

  • Sales consultancy and training. Instead of outsourcing the sales process directly, you engage external experts to evaluate and improve your internal sales strategies, processes, and team.
  • Account-based marketing outsourcing. This model is tailored for B2B companies targeting specific high-value accounts. Outsourced partners adopt this approach to create and execute personalized marketing and sales campaigns directed toward decision-makers in enterprise companies.
  • Partial outsourcing. This covers a few tasks like lead generation, sales qualification, or using the service of outsourced appointment setters. This model lets your in-house team focus on high-value activities like closing deals.
  • Full sales outsourcing. This covers lead generation to closed deals, and it suits startups that are entering new markets. However, we don’t recommend it. Joshua Pratt, outreach expert at Belkins, explains why:

What pricing models do they use?

Outsourcing vendors use 2 models to set their B2B appointment setting services cost. The first is fee-for-service. The second is pay-for-performance. See what’s included in both pricing models:

B2B appointment setting pricing models

Asking about the model a company uses ensures you don’t waste time with brands that are not a fit. Belkins uses the retainer model, enabling clients to access its comprehensive bundle of services. Below is a quick rundown of what goes into our process and pricing:

Can they walk you through their sales process?

What’s the workflow process of your preferred vendor? Is it flexible? 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 experiences show you July and August are slow months for sales because of the summer holidays, give your input and shift resources to other high-value activities.

Will you work with dedicated sales outsourcing experts?

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

The latter is problematic 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 or lack expertise in multiple areas.

Do they offer flexible engagement contracts?

Some B2B sales outsourcing companies offer month-to-month contracts. Others have fixed contract terms, and few have flexible engagement arrangements. If you’re uncomfortable with any of these contract types, ask the vendor if they are flexible so you can decide to move forward or look for another vendor to work with.

Is their tech stack ideal for your needs?

Sales prospecting, nurturing, appointment generation in B2B — the list continues. 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 should also be non-negotiables.

Do they apply a 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. 

Look 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.
