ExpertCallers is a global call center outsourcing and B2B lead generation provider offering inbound and outbound support, SDR services, and multichannel customer engagement. With over 20 years of experience and ISO-certified processes, it delivers scalable, process-driven offshore solutions.
ExpertCallers, a division of Flatworld Solutions, has been operating since 2002 as a global outsourced call center and B2B lead generation provider. Headquartered in Princeton, New Jersey, the company runs large delivery centers in India, the Philippines, and Latin America, offering a broad mix of inbound and outbound services. Its positioning is that of a mature, process-driven partner for companies that need to scale customer contact operations without building internal teams. The company holds ISO 9001 and ISO/IEC 27001 certifications and emphasizes Lean Six Sigma methodologies, KPI dashboards, and AI-augmented workflows to deliver consistent results.
The service catalog is unusually wide. On the sales side, ExpertCallers provides B2B lead generation, target account and ICP development, contact discovery and verification, multi-channel cold outreach (phone, email, LinkedIn), AI-driven lead scoring, and appointment setting. On the customer service side, it covers inbound and outbound call center operations, email, chat, and video chat support, technical help desk, customer surveys, telemarketing, and collections. It also offers less common offerings like CCTV monitoring, content moderation, and back-office administrative support. This breadth makes it a one-stop shop for companies that want to consolidate multiple outsourced functions under a single vendor.
Pricing is usage-based and hourly, not per-seat SaaS. Published rates indicate telemarketing support starts around $10 per hour, standard technical support around $15 per hour, and advanced technical support around $25 per hour. Final rates depend on call volume, project duration, complexity, coverage hours, and agent skill levels. Most engagements require a custom quote and a minimum commitment of a few months. While the headline "$1 to $25 / mo" appears on the SalesHive directory page, the actual model is far more flexible and tied to actual usage, which can be an advantage for scaling programs up or down.
ExpertCallers is best for SMB to mid-market and enterprise organizations that have enough lead volume or customer inquiries to justify a dedicated outsourced team. Its competitive offshore pricing, global 24/7 coverage, and CRM integrations (Salesforce, HubSpot, Zoho) make it a strong fit for companies that need process rigor and scalability. However, very small businesses with only occasional calls or those looking for a self-service SaaS tool may find the custom onboarding and minimum engagement durations more than they need. The lack of public customer reviews on major platforms like G2 and Capterra is a notable gap, and employee feedback on Glassdoor raises concerns about management and retention that buyers should investigate during reference calls.
Overall, ExpertCallers offers a compelling value proposition for companies that want a mature, ISO-certified outsourcing partner with a very broad service range and strong process frameworks. Its hourly pricing and global delivery footprint provide flexibility, but the managed-service model requires active vendor oversight. For organizations that can commit to a custom engagement and value process discipline over a self-service platform, ExpertCallers is a solid option worth evaluating alongside alternatives like Televerde, Peak Support, and Martal Group.
