WhatConverts is a real product solving a real problem. For businesses where most of the leads come in by phone. Call tracking is harder to do than form tracking, and they do it well.
But call tracking comes with a real cost: $30+ per tracking number per month, plus per-minute charges, plus the setup work of porting numbers and configuring IVR routing. If your leads come in through forms. Which is true for most web-based lead-gen. You’re paying for capability you don’t use.

WhatConverts or Lead Source: who picks which
The feature lists matter less than one question: which marketing brought the customer.
Pick WhatConverts if
Most of your leads come in by phone.
- You run search ads that drive phone calls (trades, locksmiths, plumbers, emergency services)
- You need call recording, transcription, or IVR routing
- You have a sales team taking inbound calls and need attribution for them
- You’re primarily US-based and want one tool that handles calls + some forms
- You can absorb $30+/month per tracking number into your CAC math
Pick Lead Source if
Most of your leads come in by form. That is the job lead source tracking was built for.
- Your enquiry path is “visitor browses site, fills out contact form”
- You don’t need call tracking and don’t want to pay for capability you won’t use
- You want one flat monthly price, not per-number fees
- You want to be live in five minutes, not after a number-porting process
Already paying for WhatConverts?
If your phone leads are minimal, or you mostly use WhatConverts for form tracking and barely touch the call features. You’re likely overpaying by $200-500/month for capability you don’t use.
What you’ll lose moving to Lead Source: call tracking, call recording, DNI, IVR routing. If those are dormant in your account, you lose nothing in practice.
What you’ll save: the per-number monthly fees, the per-minute charges, the annual contract lock-in. For most form-led lead-gen, that’s $200-400/month back.
What you’ll gain: a five-minute install, every form on the site tracked with no per-form setup, and the full page journey behind each lead.
