WHMCS Plugin: Sell AI Voice & Chat Agents as a Hosting Add-On – Now Officially Available
Bored of selling hosting? Not anymore. With the new EchoCall WHMCS plugin (from WHMCS 9.0), hosting providers sell AI Voice & Chat Agents directly from the WHMCS client area – full white-label, pay-as-you-go, zero upfront investment. A new revenue stream in just a few hours.
What is the EchoCall WHMCS Plugin?
The EchoCall WHMCS plugin is an official add-on for WHMCS (from version 9.0) that enables hosting providers, resellers, and agencies to sell AI Voice Agents and AI Chat Agents as a managed service to their end customers – completely under their own brand. No development costs, no upfront investment, no monthly fixed costs: pure pay-as-you-go, billed directly through WHMCS.
The Hosting Market Is Stagnating – AI Agents Create a New Revenue Lever
The classic web hosting market in the DACH region is barely growing. According to Statista Digital Market Outlook 2025, growth in the shared hosting segment is below 3% per year – while margins are constantly eroded by cheaper providers. For WHMCS-based hosting businesses, a dilemma emerges: same infrastructure, falling prices, falling margins. The only answer: new value-added products with genuine customer benefit.
This is exactly where the EchoCall WHMCS plugin comes in. Instead of selling only servers, domains, and email addresses, you now offer your customers something that actively advances their business: AI-powered telephone and chat automation – deployed, managed, and billed directly from your WHMCS system.
TL;DR: What the Plugin Does
- Sell AI Voice Agents: Your customers get a fully automated phone agent – configured and activated directly from the WHMCS client area
- Sell AI Chat Agents: Website chat widget, WhatsApp integration, and RAG knowledge assistants as a managed service
- Full White-Label: Your logo, your colours, your domain – your customers never see "EchoCall"
- Pay-as-you-go billing: No minimum commitment, no upfront investment. You only pay for what your customers consume. Set your own margins.
- Automatic provisioning: The agent is set up fully automatically after the customer places an order
- WHMCS client management: All AI agent customers in your familiar WHMCS interface – no second backend
- Full support from EchoCall: L2/L3 support, onboarding assistance, and documentation delivered by EchoCall – you focus on your customers
Why WHMCS Is the Perfect Sales Channel
WHMCS is the world's most widely used billing and client management system for hosting providers – over 500,000 active installations worldwide (WHMCS Ltd., 2025). This means your customers already know the interface, trust it, and use it daily to buy domains, SSL certificates, and server upgrades. The EchoCall plugin adds to this trust with a value-added product that:
– creates genuine purchase motivation (AI telephony solves a real business problem)
– generates high retention (customers who productively use an AI agent do not churn)
– generates recurring revenue (pay-as-you-go plus optional monthly base fee)
Step by Step: How the Plugin Works
- Request the plugin: Since the marketplace listing is coming shortly, you can request the WHMCS module today directly by email: team@echocall.de. The plugin package includes installation guide, licence key, and onboarding support.
- Install the plugin (WHMCS 9.0+): Standard upload to the WHMCS addon directory, enter your EchoCall API key, done. No server code, no custom development.
- Configure products: Create your own packages in the WHMCS product catalogue: e.g. "AI Starter Agent" (50 min/month), "AI Business Agent" (200 min/month) or unlimited flat packages. You set the prices and margins.
- Configure white-label: Enter your brand colours, logo, and domain in the EchoCall PartnerNet dashboard. All customer communication goes out under your brand.
- Sell: Customers order the AI Agent directly in the WHMCS client area. Automatic provisioning sets up the agent. The customer receives login credentials for their branded EchoHub dashboard.
- Bill automatically: WHMCS bills automatically based on consumption – monthly, with your individual pricing and margins.
Business Case: What Can a WHMCS Reseller Earn?
| Scenario | Parameters | Monthly Additional Revenue |
|---|---|---|
| Small provider | 10 AI agent customers, avg. €75/month | +€750/month |
| Mid-size provider | 50 AI agent customers, avg. €120/month | +€6,000/month |
| Large reseller | 200 AI agent customers, avg. €150/month | +€30,000/month |
*Example values. Actual margins depend on individual pricing and consumption. EchoCall wholesale prices are communicated in the PartnerNet dashboard.
Use Cases: What Your Customers Do with the AI Agent
