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 paid entry tiers cluster under $40 and two vendors publish a $0 base — but only one of them publishes what the usage on top costs, and adding the metered rates flips the order.
Corrected 2026-09-08. WildJar has left the cheap end of this ranking, and not because it raised a price. The $39 Starter, the $0.05 minute, the $4.50 number and the $159 Mammoth tier this guide carried all came from wildjar.com/pricing-united-states — a page nothing on WildJar’s site links to any more, whose footer still reads 2024 and whose testimonials are placeholder text. It still answers with the old rate card, which is exactly why re-verification kept confirming figures WildJar no longer charges. On the live page, WildJar’s entry tier is Starter at $150/mo, and it is a different product: an allowance of 4 tracking numbers, 500 minutes and AI transcription, with no per-minute rate published for it at all. Its metered plan is Growth/Agency at $89/mo + $0.10/min, the dearest published minute in this ranking. Mammoth has no published price in any region, and WildJar sells no annual billing of any kind. The rest of the cheap end held: Dialics $0 PAYG ($0.045/local-min), Convirza $29, WhatConverts $30 (with its $30 credit) and Ringba $147 are all confirmed, and Nimbata’s $35 is still the annual-billed price — $39 is its month-to-month rate. Three other things changed. CallRail: this guide had been calling its grid unreadable and quoting third parties; the grid is JavaScript-rendered, so a plain fetch returns nothing, but a browser reads it, and we read it. Lead Tracking is $55/mo month-to-month — the $50 we used to print is the annual-billed rate, which is what the page shows first because its billing toggle opens on Yearly — and the entry allotment meters local minutes at $0.06/min, not the $0.045 we carried, which is CallRail’s 4,000-minute rate. CallTrackingMetrics: the ranking table below was printing its live transcription rate, $0.02/min, in a column of local per-minute rates; local call forwarding is a platform-wide $0.04/min, and that is what belongs there. And Dialics is no longer the only $0 sticker on this page — Nimbata publishes a free Entry tier at $0 plus usage — though Nimbata never publishes the usage rate, so that $0 cannot be costed out.
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) on the inbound US rates it publishes, local numbers at $1/mo (toll-free $2/mo), and a 7-day trial that includes a $10 credit. It is not the only $0 sticker in the category — Nimbata publishes a free Entry tier at $0 plus usage — but Nimbata never publishes the per-answered-call rate that “plus usage” resolves to, so its $0 is a floor you cannot price. Below them the paid floor is a tight cluster, all month-to-month: Convirza Starter at $29, WhatConverts Call Tracking at $30 and Nimbata Pro at $39 ($35/mo billed annually) — three paid entry tiers inside $10 of each other, and then a $16 step to CallRail. WildJar used to make a fourth at $39 and no longer does: its entry tier is Starter at $150/mo, which buys an allowance rather than a meter, and its cheapest plan of any kind is the $89 Growth/Agency tier above it. 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, month-to-month | 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 | $39 ($35 billed annually) | per answered call, rate not published |
| CallRail | Lead Tracking | $55 ($50 billed annually) | $0.06/min |
| CallTrackingMetrics | Marketing Lite | $79 (~$65 billed annually) | $0.04/min local forwarding |
| WildJar | Growth/Agency — its cheapest plan | $89 (no annual billing published) | $0.10/min |
| Ringba | Business | $147 ($127 billed annually) | $0.055/min |
| WildJar | Starter — its entry tier | $150 (no annual billing published) | none published; 500 min + 4 numbers included |
Every base in that column is the month-to-month price, and four of these eight vendors’ pricing pages do not open on it. CallRail’s grid loads with its billing toggle set to Yearly, so $50 is the first figure a visitor sees. Nimbata’s loads on annual as well — a zero-width, transparent checkbox whose labels are drawn in CSS — and shows $35 beside a struck-through $39. CallTrackingMetrics loads on its Yearly control, at about $65. Ringba ships its pricing section in the annual state, at $127. All four of those are annual-billed rates; the column above holds the numbers that belong beside everyone else’s monthly stickers. WildJar is the exception in the other direction — it publishes no annual billing at all, so its two figures have only one basis.
WildJar appears twice because its rate card is inverted. The tier it sells as the entry point, Starter, costs $61 more than the Growth/Agency plan above it, because Starter buys an allowance — 4 tracking numbers, 500 minutes and AI transcription in one figure — and Growth/Agency buys a platform you then meter on top of. Whichever way you read it, WildJar no longer has a plan in the sub-$40 cluster.
Three of the per-minute rates carry a caveat too. CallRail’s $0.06/min is the rate on the 250-minute allotment this plan includes, not a platform-wide rate. CallTrackingMetrics’ $0.04/min is local call forwarding, which genuinely is platform-wide across Lite, Pro and Sales Engage — the $0.02/min this guide used to print in that column is its live transcription rate, a different meter on a different unit. And WildJar’s $0.10/min belongs to the $89 Growth/Agency plan alone: the $150 Starter tier publishes no per-minute rate at all, and the page says nothing about what happens once its 500 included minutes are used, so that cell stays empty rather than borrow the rate from the plan beside it.
That is the headline order, and it is genuinely tight at the bottom: $0, then three paid plans inside $10 of each other — $29, $30 and $39 — before a $16 step to CallRail. Nimbata’s $39 only sits there because it is the month-to-month price and not the $35 its page shows first. Two footnotes belong on the order. Nimbata’s free Entry tier carries a $0 sticker of its own, but it is not in the table, because the per-answered-call rate underneath it never renders on the pricing page — the rate table fills in only after a country lookup, which fails — and a $0 base with an unpublished meter cannot be ranked against a per-minute one. And Convirza’s $29, the cheapest paid sticker here, is a list price rather than a checkout: every tier’s button on that page reads “Get A Demo”, and the page does not contain the strings “sign up”, “free trial”, “buy now” or “add to cart” at all. The six quote-only names — Invoca, Marchex, Phonexa, CallSource, Retreaver and TrackDrive — publish no base at all, so they cannot enter a price ranking honestly and are left out rather than guessed at. Two priced vendors are missing for other reasons: Infinity, whose per-call model gets its own section below, and Mediahawk, which prices openly but in pounds — Starter £199/mo month-to-month (£179/mo on an annual contract) and Professional £299/mo (£269/mo annually), unlimited users on both, nothing bundled and metering from the first minute. Its page contains no ”$” character at all, so there is no dollar figure to put in this column and we do not invent one by converting at a rate the vendor does not quote.
Where the cheapness flips
Two of these plans carry their value inside the base (and we put them head to head separately). WhatConverts bundles a $30 usage credit into its $30 fee, and its own table puts the plan’s included volume at up to 148 phone call leads — so its real floor for a light user is the $30 sticker, not $30-plus-usage. CallRail’s Lead Tracking ($55/mo month-to-month, or $50 billed annually) includes 250 local minutes and 5 tracking numbers; you pay the base and nothing more until you cross those allowances, then $0.06 per local minute ($0.08 toll-free, $0.03/SMS, $0.02 per form submission, $0.05 per analysis minute, and $3 for an extra local number or $5 for an extra toll-free one — the page prints those last two as “$3 ea.” and “$5 ea.” with no billing period beside either, so read them as monthly at your own risk). CallRail’s per-minute rate does fall on bigger allotments — $0.05 at 1,000 local minutes, $0.045 at 4,000 — but each of those is a bigger allotment sold on a higher base, not the entry plan.
The pure-metered plans have no such cushion. Price a steady 1,000 local minutes a month and the ranking rearranges:
| Vendor | Base, month-to-month | + 1,000 local min | Effective monthly |
|---|---|---|---|
| Dialics | $0 | 1,000 × $0.045 | ~$45 (+$1/number) |
| CallRail | $55 | 750 billable × $0.06 | $100 |
| Convirza | $29 | 1,000 × $0.08 | ~$109 |
| WildJar Growth/Agency | $89 | 1,000 × $0.10 | ~$189 (+$8.50/number) |
CallRail’s row uses its $55 month-to-month base, to match the basis every other row here is on; on annual billing the same workload lands $5 lower. It is an entry-plan figure, though: at this volume CallRail’s own cheapest route is its 750-minute allotment at $75/mo month-to-month ($68 billed annually), where the last 250 minutes metered at $0.06 bring it to $90 — under both metered plans below it, and the figure our 1,000-minute cost breakdown uses. Either way it stays a plan with a bundled-minute cushion, not a flat fee.
The order inverts almost completely, and the plan with the cheapest WildJar base ends up dearest of the four. WildJar’s $89 Growth/Agency tier lands at ~$189 because it carries the steepest published minute in this guide, $0.10 — more than double Dialics’ $0.045 — with $8.50 a number on top of that. Convirza’s $29, the cheapest paid sticker in the ranking above, lands third at ~$109: a low base hiding a $0.08/min rate and $3.00 per number, enough to overtake CallRail at this volume. Dialics, which looked like a curiosity at $0, is the cheapest real answer in this table precisely because its only cost is usage and that usage is priced at the floor of the market — matched, from outside it, by WhatConverts, whose $30 base carries a $30 usage credit and meters at the same $0.045, landing it at about $45 as well (our 1,000-minute breakdown prices that row in full, including the 148-call ceiling on the credit). WildJar’s $150 Starter cannot be put in this table at all: 500 of the 1,000 minutes are inside its allowance, and for the other 500 the page publishes no rate and says nothing about what happens — so there is no honest figure to compute, and we leave the row out rather than model the silence.
The per-call wrinkle
Two vendors don’t meter minutes at all. Nimbata (Pro $39/mo month-to-month, $35/mo billed annually) and Infinity bill per answered call regardless of length — 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 $39 can undercut a per-minute plan that looks cheaper on the sticker. Only one of the two can be costed, though. Infinity publishes both halves of its model — Essentials at $249/mo plus $0.20 per tracked call — while Nimbata publishes the base and not the rate, on the free Entry tier and the paid ones alike. That is why Nimbata appears in the base ranking above and in none of the volume tables.
How to read this
The lowest entry price to get started is $0 (Dialics, pay-as-you-go) — matched on the sticker by Nimbata’s free Entry tier, which doesn’t publish the usage rate underneath it — and the cheapest paid base is $29 (Convirza), which is a demo-gated list price rather than something you can sign up for unaided. But the only two figures you can take at face value are the bundled ones — WhatConverts’ $30 (with its $30 credit, and up to 148 call leads included by the vendor’s own table) and CallRail’s $55 month-to-month ($50 billed annually, with 250 local minutes and 5 numbers included, then $0.06/min) — 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 — or WhatConverts, metering at the same $0.045 behind its $30 credit — not Convirza at $29 + $0.08/min. WildJar, which used to sit in the sub-$40 cluster at $39, is out of it entirely: its entry tier is a $150 allowance with no published meter under it, and its cheapest plan of any kind is $89 with the steepest minute on the board. Fix your monthly minutes before you rank, and check which billing basis a sticker is quoted on — half the pages in this table open on annual — because in this category the base price and the bill are two different numbers.
