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:

VendorEntry planMonthly baseLocal per-minute rate
DialicsPay As You Go$0$0.045/min
ConvirzaStarter$29$0.08/min
WhatConvertsCall Tracking$30$0.045/min
NimbataPro$35per answered call
WildJarStarter$39$0.05/min
CallRailLead Tracking$50$0.045/min
CallTrackingMetricsMarketing Lite$79live transcription $0.02/min
RingbaBusiness$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:

VendorBase+ 1,000 local minEffective monthly
Dialics$01,000 × $0.045~$45 (+$1/number)
CallRail$50750 billable × $0.045~$83.75
WildJar$391,000 × $0.05~$89
Convirza$291,000 × $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.
