How Companies Achieve 300–400% ROI in 90 Days by Replacing Human Teams with VoxAgent
Epsylon Systems LLC
Miami, Florida
Internal Document v1.0 – November 2025
Human teams—whether Sales Development Representatives (SDRs), support agents, or booking specialists—are one of the most expensive and inefficient components of modern business operations. On average, a single role costs $70,000+ annually when accounting for salary, benefits, turnover, training, and tools—yet delivers inconsistent performance.
This whitepaper presents a realistic financial model showing how businesses can replace human teams with VoxAgent AI voice agents, achieving 300–400% ROI within 90 days while reducing operational costs by up to 85%.
We do not rely on hype or hypothetical claims. Our analysis is based on:
VoxAgent is developed by Epsylon Systems LLC, a US-based AI innovation company. Product decisions, compliance, and operations are managed from our office at 1000 Brickell Avenue, Miami, FL.
Most companies only see direct salaries when calculating team costs. But the Total Cost of Ownership (TCO) is far higher.
| Expense Category | Cost Per Role / Year |
|---|---|
| Base Salary | $55,000 |
| Payroll Taxes & Benefits | $16,500 |
| CRM & Dialer Tools | $3,600 |
| Training & Ramp-Up | $6,000 |
| Turnover Rate (35%) | $24,500 |
| Total Effective Cost | $105,600 |
With a typical team of 5 roles, this totals $528,000/year — before management overhead.
Yet performance remains low:
Only 60–70% of an agent’s time is spent selling or serving customers. The rest goes to admin, CRM entry, follow-up emails, and downtime.
VoxAgent is an AI-powered voice assistant that conducts natural-sounding conversations in real-time across 100+ languages. It handles lead qualification, appointment setting, customer support, and outbound campaigns — 24/7, without fatigue.
Built by Epsylon Systems, it combines:
Unlike chatbots, VoxAgent operates via phone calls — the channel where most B2B conversions happen.
Latency is under 200ms, making interactions feel human. Conversations adapt dynamically to tone, intent, and history.
At $1.02 per call, VoxAgent reduces the cost per qualified lead by 85% compared to human teams.

Miami is not just a mailbox — it’s our command center for product delivery, client success, and regulatory compliance.

Return on Investment (ROI) = (Gains – Costs) / Costs × 100%
In this model:
We use conservative assumptions to ensure credibility:
For a team of 5 SDRs costing $70,000 each:
($350,000 – $18,988) / $18,988 = 1,743% ROI
We present a more modest projection of 300–400% ROI to account for internal transition costs and optimization time.
