How agencies and resellers make real money with call tracking

Reselling call tracking is one of the highest-margin services an Indian digital agency can add. Here’s the playbook.

If you run a digital marketing agency in India, you already manage your clients’ Google Ads, websites and lead pipelines. The one thing you usually don’t own is the phone number — and that’s leaving money on the table.

The margin math

Wholesale rates on Plivo for an Indian DID are roughly ₹500-800/month. Most agencies happily pay ₹2,000-3,000/month for the same number when it’s wrapped in proper attribution, CRM and reporting. That’s a 3-4x markup — recurring.

The operating reality

The catch: you can’t actually run that as a business if you’re forwarding emails between Plivo’s portal, a spreadsheet of clients, and a separate invoicing tool. That’s why most agencies that try call tracking abandon it within 60 days.

What you actually need

A multi-tenant platform with proper org isolation
White-label branding (your logo, your domain)
GST-ready invoicing
Per-client rate cards and margin views
One wallet to top up, one place to see usage across all clients

That’s exactly what Callswala’s reseller suite is built for.
