Guide · Call Tracking
The cheapest call tracking software in 2026 is free to start — until you turn the phones on
Ranked strictly by published monthly base, the cheapest entry tiers cluster under $40 with one true $0 pay-as-you-go option — but add the per-minute rates these platforms meter on top and the order flips.
If “cheapest” means the lowest published monthly base to open an account, the answer is Dialics at $0 — a pure pay-as-you-go plan with no named subscription tier, just metered usage at $0.045 per local minute (toll-free $0.055/min), local numbers at $1/mo, and a 7-day trial that includes a $10 credit. Below the one free option, the paid floor is a tight cluster: Convirza Starter at $29, WhatConverts Call Tracking at $30, Nimbata Pro at $35, and WildJar Starter at $39 — every entry tier in the dataset that publishes a base price sits under $40 except the incumbents. But none of these numbers is what you pay, because call tracking bills subscription plus usage, and the cheapness inverts the moment the phones ring.
The published-base ranking
Ranked strictly by recurring monthly base, ignoring usage:
| Vendor | Entry plan | Monthly base | Local per-minute rate |
|---|---|---|---|
| Dialics | Pay As You Go | $0 | $0.045/min |
| Convirza | Starter | $29 | $0.08/min |
| WhatConverts | Call Tracking | $30 | $0.045/min |
| Nimbata | Pro | $35 | per answered call |
| WildJar | Starter | $39 | $0.05/min |
| CallRail | Lead Tracking | $50 | $0.045/min |
| CallTrackingMetrics | Marketing Lite | $79 | live transcription $0.02/min |
| Ringba | Business | $147 | $0.055/min |
That is the headline order, and it is genuinely tight at the bottom: $0, then four plans within $10 of each other. The quote-only enterprise names — Invoca, Marchex, Phonexa, CallSource, Retreaver — publish no base at all, so they cannot enter a price ranking honestly and are left out rather than guessed at.
Where the cheapness flips
Two of these plans carry their value inside the base. WhatConverts bundles a $30 usage credit into its $30 fee, covering roughly 148 calls before any overage — so its real floor for a light user is the $30 sticker, not $30-plus-usage. CallRail’s $50 Lead Tracking includes 250 local minutes and 5 tracking numbers; you pay the base and nothing more until you cross those allowances, then $0.045/min.
The pure-metered plans have no such cushion. Price a steady 1,000 local minutes a month and the ranking rearranges:
| Vendor | Base | + 1,000 local min | Effective monthly |
|---|---|---|---|
| Dialics | $0 | 1,000 × $0.045 | ~$45 (+$1/number) |
| CallRail | $50 | 750 billable × $0.045 | ~$83.75 |
| WildJar | $39 | 1,000 × $0.05 | ~$89 |
| Convirza | $29 | 1,000 × $0.08 | ~$109 |
The $29 plan becomes the most expensive of the four. Convirza’s low base hides the highest per-minute rate in this group — $0.08/min plus $3.00 per number — so at volume it overtakes WildJar, CallRail, and the nominally-free Dialics. Dialics, which looked like a curiosity at $0, is the cheapest real answer at this workload precisely because its only cost is usage and that usage is priced at the floor of the market.
The per-call wrinkle
Two vendors don’t meter minutes at all. Nimbata ($35 Pro) and Infinity bill per answered call regardless of length — Nimbata doesn’t publish its per-call rate on the page, so it can’t be normalized against the per-minute field, but the model matters: short calls are penalized and long ones are cheap, the mirror image of per-minute billing. If your calls run long, a per-call base like Nimbata’s $35 can undercut a per-minute plan that looks cheaper on the sticker.
How to read this
The lowest entry price to get started is $0 (Dialics, pay-as-you-go), and the cheapest paid base is $29 (Convirza). But the only two figures you can take at face value are the bundled ones — WhatConverts’ $30 (with its $30 credit covering ~148 calls) and CallRail’s $50 (with 250 minutes and 5 numbers included) — and the cheapest plan at any real volume is whichever pairs a low base with a low per-minute rate, which is Dialics at $0 + $0.045/min, not Convirza at $29 + $0.08/min. Fix your monthly minutes before you rank, because in this category the base price and the bill are two different numbers.
