What is the best call tracking software for agencies in 2026?

WhatConverts has the clearest agency pricing in the category. Its "Unlimited Accounts" plans give you as many client accounts as you need: Plus at $500 a month ($250 of usage credit, up to 1,908 calls and 2,500 forms, chats or transactions), Pro at $800 ($300 credit, 2,325 calls) and Elite at $1,250 ($400 credit, 3,158 calls). Usage is also cheaper on agency plans: a local number costs $1.75 and a local minute 4 cents, against $2.50 and 4.5 cents on a single account. Toll-free numbers run $3.00 and 6 cents a minute.

The usage credit is what makes the bill predictable. Take 10 clients with 3 local numbers and 300 minutes each: 30 numbers come to $52.50, 3,000 minutes to $120, so $172.50 of usage sits inside the $250 credit. Add the $50 white label, which puts your branding on the dashboard and the emails, and you pay $550 a month all in. Transcription is 2 cents a minute, texts 3 cents, tracked forms and chats 10 cents each.

Agencies on review sites praise the support more than anything else. Two caveats come up: moving to a master agency account takes some learning, and users mention a single white-label setup per email address, so one brand for the agency rather than one per client.

Nimbata is the cheapest real agency plan here. Agency costs $149 a month ($120 with the annual discount) and includes unlimited seats and projects, the Salesforce integration, the API, webhooks and dedicated support. You open one project per client and your team works from a single login. White label is a $55 monthly add-on on Agency.

Billing works per answered call, not per minute or per number, so a quiet client costs very little. The catch is that the price per answered call isn't printed on the pricing page; you get it from a calculator. A fair-use rule also kicks in when the average call runs over 3.5 minutes, and transcription costs $0.02 a minute. For 10 clients, the base is $204 a month ($149 plus $55), or $175 on annual billing, before answered calls.

Two things set it apart for agencies. Numbers are available in more than 70 countries, which helps when you run campaigns abroad. And the partner program flips the cash flow: Nimbata bills your client directly and pays you a 15% lifetime commission, so you stop fronting software costs for clients.

CTM has the deepest agency feature set. Marketing Pro, at $179 a month ($149 annual), calls itself agency-friendly and includes 25 sub-accounts: one per client, each with its own numbers, reports and 3,000 transcribed minutes. Extra packs of 25 sub-accounts cost $50 a month, and Sales Engage ($329) and Enterprise move to unlimited sub-accounts.

Full white label costs $65 per domain, per agency: your domain, your logo, your product. CTM also offers client billing setup. For 10 clients, the subscription comes to $244 a month ($179 plus $65), or $214 on annual billing. Number and minute rates aren't listed on the pricing page, so ask for them in writing; CTM also warns that numbers outside the US may require extra documentation.

In reviews, some agencies complain that the invoice doesn't break down usage per client account, which turns rebilling into a manual job. Setting up many accounts takes time too: the reporting is powerful but not intuitive at first. Marketing Lite doesn't show how many sub-accounts it includes, so treat Pro as the real agency entry point.

CallScaler wins on usage prices. The Call Tracking plan costs $65 a month and covers 3 businesses with 5 users each. Unlimited businesses and users add $95 a month, and white label adds $65. Usage is very cheap: $0.50 a month per local number, $2 for toll-free, 4.5 cents a local minute, half a cent a minute for recording, and 0.6 cents per 15 seconds of AI transcription.

For 10 clients, the math gives $225 of plan fees ($65 + $95 + $65), plus $15 for 30 local numbers and $135 for 3,000 minutes: about $375 a month with your branding. The Pay Per Call plan at $400 a month includes unlimited businesses and white label, which suits lead generation agencies that sell calls rather than reports.

The limit is geography: CallScaler lists only US numbers on its pricing page. If one of your clients sells in Canada, the UK or Australia, you'll need a second tool for that account.

Before you pay for software, check what Google Ads already does. Google forwarding numbers are generated dynamically and free to use; they track calls from Search ads, with an adjustable minimum call length so only real conversations count. You still pay for the click as usual.

For an agency, the limit is clear. Everything lives account by account: your only multi-client view is your manager account (MCC), with no shared call report. Calls from organic search, the Business Profile or Meta campaigns don't show up at all, so you can't show a client the share of each channel, which is usually why agencies buy a tool in the first place.

It keeps a job even next to a paid tool: offline call conversion import. Your tracking tool sends qualified calls into Google Ads, where they appear within three hours, as long as conversion tracking was active at the time of the call.

CallRail is the name most agencies search for, and the most expensive at ten clients. Its pricing page shows no agency plan and no white label. The Account Center gives you one master login to manage every client's campaigns, but pricing is set at the account level: one subscription per client, from $50 a month on Lead Tracking, with up to 10% off on annual billing.

Each account includes 5 local numbers, 250 local minutes and 25 texts. Beyond that, a local number costs $3 and a minute 5 to 6 cents; toll-free numbers run $5 and 8 cents a minute. For 10 clients with 3 numbers and 300 minutes each, plan on $525 to $530 a month: $500 of subscriptions plus 50 overage minutes per client. Reviewers report minutes billed past 250 without warning, and cancellations harder than sign-ups.

Its real strength for agencies is ownership: you can grant each client ownership of its own account, which makes the end of a contract clean. A PPC agency with more than 500 clients says adding a new account takes a few clicks.
