Appointment setting is a numbers game: You can have 0.5% conversion or 3% conversion to make this work. So 1,000 leads can convert into 5 appointments or 25 depending on multiple factors.

If you don’t have the in-house capacity or lack expertise, you can be stuck at 0.5% (5 appointments). Outsourced partners like Belkins can increase your B2B sales outcomes including more appointments and successful conversions, so the whole channel can actually look different.

We at Belkins know the markers of success in appointment setting services. For example, our expertise drove a 297% YoY growth and spurred a pipeline increase exceeding $10M for our clients’ businesses. Nevertheless, we understand that our expertise might not be a perfect match for every particular project and scenario.

But fret not, as we have curated the 7 best B2B appointment setting companies in 2023. Each offering in the list possesses unique strengths to cater to your diverse requirements.

Criteria for choosing the best B2B appointment setting agency

If you decide to outsource sales appointment setting, this should be a strategic move offering a cost-effective extension or even a potential replacement for your in-house sales operations. 

However, it comes with its fair share of challenges and risks. One of the key considerations is ensuring they have a deep understanding of your business domain and how it operates. Another crucial aspect is evaluating the effectiveness of their appointment setting process.

So let’s review several pivotal factors.

Criteria 1: Credibility backed with social proof

Outsourcing any business process always involves researching public customer feedback. Look for a reputable partner with a stack of positive reviews and be sure to watch out for objectives and achievements articulated in clear terms, such as:

"With our assistance, the marketing and advertising company achieved 3x YoY growth, secured a $1.5M deal in the pipeline, and booked 25 appointments within just 3 months."

Now, here’s a word of caution — watch out for the fake-it-till-you-make-it trick! This dishonest approach includes creating fake reviews or case studies to appear more successful than a company truly is.

To ensure you’re getting authentic testimonials, head over to external review sites like Clutch and G2. Ask your team representatives to thoroughly vet each client represented in their portfolio. Besides, pay attention to the video testimonials: They are very hard to forge.

Word of mouth remains a potent force, and B2B agencies are no exception. To discover reliable appointment setting companies, you can inquire within niche groups on LinkedIn (e.g., Chief Executives, CMO Network) or communities like Forbes Councils, Indie Hackers, and BLKNS. You can also connect with industry events. 

Criteria 2: A team of experts aboard

When selecting appointment setting firms, having a competent B2B sales team is crucial for effective and efficient lead generation. Verify their expertise through certifications, awards, and industry recognition.

Additionally, check LinkedIn or similar platforms to authenticate their experience, connections, endorsements, and activities. Beware of embellished achievements or skills, as the issue with millions of fake LinkedIn accounts continues to be a significant concern.

Consider the following critical points about the agency’s staff:

  • Expertise range: Understand the variety of skills, knowledge, and experiences they offer for crafting successful appointment setting strategies.
  • Alignment with your company: Ensure they resonate with your company’s culture, values, and mission for a fruitful collaboration.
  • Problem-solving ability: Look for team members who are innovative and adept at overcoming challenges, ensuring smooth lead generation processes.

Assessing these areas guarantees a skilled team aligned with your goals, prepared to excel in appointment setting tasks. You can trust such a vendor with no doubts, regardless of its location.

Criteria 3: Industry expertise and focused approach 

Understanding your industry’s specifics, target audience, and challenges allows the company to customize its approach and generate top-notch leads. You can easily check it by going through the company’s case studies.

For example, here’s a glimpse into our own processes we developed for 2 different sectors and described in our success stories.





It’s hard to connect with the right decision-maker.

Selling general business consulting is highly competitive.


Avoid reaching out directly to busy C-level executives but approach preselected employees to find an internal champion. 

Narrow down your ICP and reach out to smaller companies’ CEOs and CIOs. 


When re-engaging unresponsive prospects, employ tailored variables for different industries.

Divide your portfolio into smaller products and promote them separately to a specific target audience.

Criteria 4: What’s special about their framework?

When it comes to business visibility, it’s essential to learn how much your chosen vendor prioritizes openness with their techniques, processes, and approaches.

  1. Are their marketing materials packed with practical, insightful advice they follow themselves, or do they merely post generic content? Do you like the content on their own site and social media?
  2. What kind of techniques and tools do they use to qualify prospects they are about to approach?
  3. How deeply and creatively do they craft email templates, targeting both bulk audiences and individuals?

Understanding the “why” behind their actions and the “how” behind their strategies can give you valuable insights into their level of transparency and expertise. B2B appointment setting companies that lack clarity on their methods might raise suspicions.
