2. Revit: best for pay-per-appointment lead generation

• Industry focus: SMBs, startups
• Notable clients: ClickRoads, Folderly, Wordstir
• Pricing: Pay-per-appointment packages start at $300, with month-to-month plans also available

Revit is a pay-per-appointment (PPA) lead generation company. They specialize in low-commitment outsourced B2B lead generation, a results-oriented framework where businesses only pay for leads that result in actual sales calls. 

This appointment setting model is a good fit for startups or new companies who haven’t established a solid sales department yet. Since PPA is more flexible in terms of costs and contracts than typical sales appointment services, it’s also great for small and medium-sized (SMB) companies that want to optimize their marketing budgets. 

By keeping appointment volumes low but still getting quality leads, these types of companies can scale up, control costs, and increase revenue. 

Strengths:

• Results-based model: Revit is prized for their emphasis on actual results, with a streamlined approach that focuses on achieving specific outcomes rather than a high volume of leads. With PPA, your marketing spend is directly correlated to the number of sales opportunities created.
• Cost efficiency: Budget allocation becomes simpler and more effective. Since clients only pay for leads that result in confirmed appointments, PPA reduces the risk of wasted resources on prospects that don't convert. This cost-efficient model ensures you're investing your marketing budget directly into quality leads. 
• Scalability: With a PPA model, you can adjust the volume of appointments based on your specific needs and budget. Whether you're looking to ramp up sales or maintain a steady flow of appointments, Revit offers flexibility to scale your efforts accordingly.

Case studies:

• After collaborating with Revit, ClickRoads, a marketing agency, saw a 163% increase in ROI, with 6–8 appointments booked per month.
• Boutique copywriting agency Wordstir achieved a fantastic 194% increase in ROI, with an average cost of $500–$650 per appointment and a 63.4% email open rate.

3. SalesRoads: Best best for fast-growing brands

• Industry focus: Manufacturing, SaaS, advertising, oil and gas, construction, and logistics
• Notable clients: Shell, Parker, Clean Energy, Microsoft, Quest Diagnostics
• Pricing: Custom quotes, but reviews indicate pricing starts at $10,000 per month

The process involves researching clients’ businesses and their respective markets, designing a tailored strategy, testing and evaluating campaign performance, and optimizing based on results.
• Thorough reporting: With sales cycles sometimes lasting 6–12 months depending on the size of the client, SalesRoads provides detailed weekly or monthly reports of their call data, so their clients always know how their billable hours are being spent.

Case studies:

• SalesRoads built a specialized SDR team to set appointments for Körber Supply Chain’s AMR and Voice solutions. The results were 246 appointments set in 9 months, $6.2M in pipeline generated, and $1M+ in closed revenue.

How to choose the best B2B appointment setting agency

Deciding to outsource sales appointment setting should be a strategic move based on clear, objective factors. Here are the 4 most important aspects to take into account when interviewing appointment setting agencies or companies to partner up with:

1. Credibility backed by social proof

Outsourcing any business process starts with doing your homework on customer feedback. Look for a reputable partner with a solid track record of positive reviews that highlight specific results, 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." 

Michael Maximoff, on how Belkins led to outstanding results for Maark

Watch out for the fake-it-till-you-make-it trick. This dishonest approach includes creating fake reviews or case studies to make the company appear more successful than it truly is.

To make sure you're getting genuine testimonials, check out external review sites like Clutch and G2, have your team thoroughly vet each client in the partner's portfolio, and don't forget about video testimonials — they're tough to fake.

2. Industry expertise and focused approach

Understanding the unique aspects of your industry, target audience, and challenges is key to tailoring your approach and generating high-quality leads.

You can see this in action by reviewing a company's case studies. For instance, take a look at how we've customized our processes for two different sectors, as outlined in our success stories:

3. Pricing model and value for money

Make sure the company is upfront about what their pricing includes, and any potential extra charges. Consider different pricing options, like paying per appointment or a fixed project fee, and choose what works best for your budget and needs.

Also, think about the value you'll get from their service. Look at the quality of leads they generate, the expertise of their team, and their past success. Aim for a balance between affordability and quality to ensure you're getting the most out of your investment.

4. Framework and processes

Understanding the why behind a company’s actions and the how behind their strategies gives you valuable insights into their level of transparency and expertise. B2B appointment setting companies that aren't clear about their methods might make you question their credibility.

Learn how much your chosen vendor prioritizes openness with their techniques, processes, and approaches:

1. Do their marketing materials offer practical, insightful advice based on experience, or do they just post generic content?
2. What methods and tools do they use to qualify prospects before reaching out to them?
3. How thorough and creative are they in crafting email templates? Are they tailored for both mass outreach and individualized communication?

Ready to get started?

Nurturing leads takes time and effort — resources you'd rather spend on closing deals, not chasing no-shows. That's why you've decided to outsource appointment setting in the first place and leave it to the experts. Smart choice.

Companies like Belkins can significantly improve your B2B sales results by generating more appointments and increasing successful conversions — boosting lead generation ROI by 150%. This could completely transform your sales pipeline.
