Guide · Call Tracking
If you only need call conversions in Google Ads, you're shopping for a price floor — not a feature
Every call-tracking vendor with a published price in our dataset already lists Google Ads conversion import, so the import itself buys you nothing — the decision collapses to the cheapest way to keep a tracking number on.
You asked the right narrowing question — “I just need call conversions in Google Ads” — and the answer to it is liberating: that single requirement filters out almost nothing. Google Ads is the most widely listed integration in this category — 14 of the 16 vendors in our dataset name it, including every vendor that publishes a price at all. All ten priced vendors carry it (CallRail, WhatConverts, Convirza, Dialics, WildJar, Nimbata, CallTrackingMetrics, Ringba, Infinity, Mediahawk), as do four of the six quote-only platforms (Invoca, Marchex, Phonexa, CallSource). The only two that don’t list Google Ads at all are Retreaver and TrackDrive — both pay-per-call routing platforms whose published integrations are limited to Zapier, webhooks, an API, and — for Retreaver alone — two CRMs — and neither publishes a price either, so they fall outside a price-floor question regardless. When a feature is effectively universal among the vendors that publish a number at all, it stops being a tiebreaker. So you aren’t choosing on capability. You’re choosing on the price floor.
The floor, cheapest first
Among the vendors that publish a dollar price at all, here’s the bottom of the table:
| Vendor | Plan | Monthly base, month-to-month | Metered rate (local) | Google Ads |
|---|---|---|---|---|
| Dialics | Pay As You Go | $0 | $0.045/min | Yes |
| Convirza | Starter | $29 | $0.08/min | Yes |
| WhatConverts | Call Tracking | $30 | $0.045/min (up to 148 call leads included) | Yes |
| Nimbata | Pro | $39 ($35 billed annually) | per answered call (rate not published) | Yes |
| CallRail | Lead Tracking | $55 ($50 billed annually) | $0.06/min (250 min + 5 numbers incl.) | Yes |
Two rows moved since this table was last checked. Nimbata’s entry plan is $39/mo month-to-month, not the $35 printed here before — $35 is its annual-billed rate, and its pricing page loads with the billing toggle already set to annual, so $35 is simply the first figure a visitor sees. And WildJar has left the floor table altogether. The $39 Starter tier that held its row came from wildjar.com/pricing-united-states, a page nothing on WildJar’s site links to any more and which still answers with the old rate card. On the live pricing page WildJar’s US Starter is $150/mo — 4 tracking numbers, 500 minutes and AI transcription bundled, with no per-minute rate published — and its cheapest US base is the $89/mo Growth/Agency plan at $0.10/min. Neither is a price floor; WildJar’s entry tier is now dearer than the tier above it. What is left below CallRail is a three-step paid ladder of $29, $30 and $39.
The floor among every priced vendor here is Dialics at $0 base. It is not the only $0 sticker — Nimbata publishes a free Entry tier at $0 plus usage as well — but Nimbata does not publish the per-answered-call rate that usage is billed at, so Dialics is the only $0 base whose bill you can work out before you sign anything. (The six quote-only platforms publish no base at all, so they don’t undercut it either; they simply can’t be compared on a number.) Dialics bills pure pay-as-you-go — local numbers at $1/mo, local minutes at $0.045, toll-free at $0.055, transcription at $0.02/min, on the inbound US rates its table publishes — and ships a 7-day trial plus a $10 credit. If your only job is to forward a Google Ads call as a conversion, a $0 platform fee plus a $1/mo number plus a few cents a minute is genuinely the least you can pay. Its integration list is short by design — Google Ads, Zapier, and an API — but Google Ads is on it, and that’s your whole requirement.
Why the named-plan answer is ~$30, not $0
A $0 base looks unbeatable until you remember what a base price buys: a predictable line item and a vendor that isn’t pricing the trial as the product. If you’d rather pay for a named plan than assemble a pure-usage bill, the lowest sticker is Convirza’s Starter at $29/mo month-to-month (then $0.08/min, $3.00 per number) — though “pay for a plan” overstates what that page offers you: every tier’s button on it reads “Get A Demo”, with no sign-up, free trial or cart anywhere, so $29 is a list price you request rather than one you can start on this afternoon. WhatConverts’ Call Tracking at $30/mo sits a dollar behind, folds a $30 usage credit into that fee, and states in its own table that the plan includes up to 148 phone call leads before metering starts. For a low-volume advertiser, that inclusion can make the effective cost of $30 lower than it reads.
The gap between these two and Dialics is small enough that it’s not really a money decision — it’s a “do I want a usage credit and a named tier, or the rawest possible meter” decision. Both answers are correct; they’re answers to slightly different questions. The one thing that does separate them is how you buy: Convirza’s $29 goes through a demo, and the other two publish rates you can act on directly.
What you’re declining when you skip the rest of the column
It’s worth being honest about what the cheap floor leaves on the table, because that’s the actual trade. CallRail sits at $55/mo month-to-month — $50/mo billed annually, which is the figure its own page shows first, but $55 is the number that lines up against every other row here — and that puts it at the top of this five-row floor table, with the category climbing well beyond it (CallTrackingMetrics opens at $79 month-to-month, WildJar at $89 for Growth/Agency and $150 for its bundled Starter tier, Ringba at $147, Infinity at $249; Mediahawk, the one GBP-only vendor in the dataset, publishes its prices openly — £199/mo and £299/mo month-to-month — but in pounds only, so it has no dollar figure to rank against these). In exchange it bundles 250 local minutes and 5 numbers and advertises 700+ integrations, one of the broadest native integration directories in the dataset (WhatConverts counters with Zapier access to 2,000+ apps). Nimbata ($39/mo month-to-month, $35/mo billed annually) bills per answered call rather than per minute, which is a different and sometimes cheaper shape if your calls run long — though it never publishes the per-call rate, so you cannot model it in advance. None of that matters to your stated job. You said call conversions into Google Ads, full stop — and that line item is identical whether you pay $0 or $55.
A caveat on Dialics worth flagging: some third-party directories cite a ~$99/mo entry for it, but the live vendor page publishes pure pay-as-you-go with no named monthly base, which is why the floor here is recorded as $0. Confirm on the pricing page before you commit, because that’s exactly the kind of figure that drifts.
The one-line answer
Cheapest priced vendor that pushes call conversions into Google Ads: Dialics at $0 base (then ~$0.045/min and $1/mo per number). Cheapest named plan: Convirza at $29 — a demo-gated list price, not a checkout — or WhatConverts at $30, the latter with a $30 usage credit and up to 148 call leads included. Above that you’re paying for bundled minutes, integration breadth, or a per-call billing model — none of which your question asked for. The conversion import is effectively free in the sense that every vendor you can buy on a published price includes it; what you’re really buying is the cheapest dial tone to attach it to.
