The best call tracking software for agencies in 2026 is Nimbata for the best overall value and full white-label, CallRail for large multi-service agencies, and WhatConverts for reporting-heavy teams. The right choice comes down to your white-label needs, client count, and budget per account.
For an agency, call tracking is not a nice-to-have. The highest-value leads your clients get usually come by phone, and if you cannot tie a call back to the campaign, keyword, or ad that drove it, you are reporting half the story. Agency-grade call tracking ties every call to a source, lets you run every client from one login, and brands the whole thing as your own. This guide compares the seven best options (if you run a single business, use our best call tracking software roundup instead).

| CallRail | Large multi-service agencies | Deepest integrations, mature agency program | $55 | Costs climb fast across many clients |
| WhatConverts | Reporting-heavy agencies | Lead-level reporting and dashboards | $30 | More lead tool than pure call tool |

| Infinity | Enterprise and global agencies | Enterprise call intelligence and attribution at scale | $246 | Enterprise pricing and setup; heavy for small agencies |
How we picked
We evaluated each platform the way an agency actually buys: can you manage many clients from one place, can you brand it as your own, does the reporting survive a client QBR, does it connect to Google Ads and GA4 without a developer, and does the pricing still make sense at your tenth client instead of your first
What Is Call Tracking Software for Agencies?
Call tracking software for agencies is a platform that assigns tracking numbers to client campaigns, attributes every inbound call to its source, keyword, and campaign, and lets you manage all of it across multiple client accounts from a single login. Unlike single-business call tracking, agency call tracking adds white-label branding, per-client workspaces, client-ready reporting, and partner pricing, so an agency can run it at scale and resell it as its own service.
In plain terms: it lets you prove to each client which channels make the phone ring, report it under your own brand, and turn attribution into a recurring revenue line instead of a cost.
What to look for in Call Tracking Software for Agencies
Buying for an agency is not the same as buying for one business. A feature that is “nice to have” for a single company becomes a daily tax when you multiply it by twenty clients. Prioritize these:
- White-label and branding. Can you put your logo on the dashboard, use your own domain, and give clients a login that never says a competitor’s name? White-label is what turns call tracking from a cost into a service you own.
- Multi-account management. One login, many client workspaces, clean separation of numbers, data, and users. If you have to log in and out to switch clients, walk away.
- Client-ready reporting. Dashboards and scheduled reports a client can read without you translating. Bonus points for GA4, Google Ads, and Looker Studio connections so calls show up next to the rest of the media plan.
- Reselling and markup. The best agency tools let you buy at agency rates and resell to clients at your price. That is margin, not just a line item.
- Attribution depth. Dynamic number insertion, keyword-level tracking, and multi-touch attribution, so you can prove which channel drove the call, not just that a call happened.
- Pricing that scales per client. Flat platform fees and fair per-number pricing beat plans that punish you for growth.
- Support and onboarding. When a client’s numbers break at 4pm on a Friday, you need an answer, not a ticket queue.
Keep those seven in mind as you read. Most tools nail two or three. The ones below get closest to all seven.
The 7 Best Call Tracking Software for Agencies to try in 2026
1. Nimbata (Best overall value and white-label for agencies)
Nimbata Customizable Dashboard via Nimbata
Nimbata was built for the person reading this: the marketer or agency owner who needs call attribution across a roster of clients without paying enterprise prices or babysitting a clunky setup.
The agency story is simple. You get full white-label, so the dashboard, the reports, and the login wear your brand, not ours. You run each client in their own workspace, keep data cleanly separated, and switch between them without logging out. You buy at partner rates and resell at your price, which turns call tracking into a margin line instead of a pass-through cost.
Underneath the agency layer, the fundamentals are strong: dynamic number insertion, keyword-level and multi-touch attribution, call recordings and transcripts, and AI that scores and tags calls so a client’s report shows lead quality, not just volume. It pushes conversions straight into Google Ads, GA4, Microsoft Ads, Meta, and your CRM, so calls sit next to every other channel in the media plan.
Key features and highlights
- True white-label: your branding, custom domain, and client logins across dashboards and reports.
- Per-client workspaces and a partner program: manage every client from one login and resell at agency margins.
- Attribution that closes the loop: DNI, keyword-level tracking, and conversion push to Google Ads, GA4, and CRMs, so a call becomes a measurable, revenue-tagged lead.
Pricing
- Entry plan: affordable monthly base with pay-as-you-go numbers and minutes.
- Agency / partner plan: volume rates built for reselling.
- Custom: for larger portfolios.
Ratings
- G2: 4.7/5
- Capterra: 4.8/5
When Nimbata is not an ideal choice: if your client specifically asks for a big-name incumbent by brand, Nimbata does not have CallRail’s market recognition yet (even where it matches or beats it on features and price).
Skip Nimbata if: you need a full contact-center phone system rather than marketing call attribution.
What are real users saying about Nimbata?
What do you like best about Nimbata?
As an agency, we’ve used a lot of different tools, but Nimbata has really blown us away. It’s super simple to use with the AI notes + Sheet integration.
One of our favorite features is the AI-powered notes. It’s a huge time-saver, giving us quick insights we can actually use. The best part? Nimbata was so easy to set up. We had it up and running in a week. To add, the customer support team is top-notch. We had a few questions during setup, and they were quick to help us out.
The Google Sheet Integration was a god send. We’re able to share this link with clients and they’re able to see directly how effective our ad campaigns are.
Their script has the technology to dynamically swap the phone numbers on the website based on where the visitor comes from (organic vs paid vs social).
What do you dislike about Nimbata?
Nothing. Honestly such a good tool specially for performance-based marketing agencies.

2. CallRail (Best for large multi-service agencies)
CallRail is the name most clients already know, and that recognition has value in a pitch. It is a mature platform with one of the deepest integration libraries in the category and a well-established agency program.
For a larger agency running many services across many clients, the breadth is the draw: call tracking, form tracking, and conversation intelligence in one place, with connectors for nearly every tool your clients already use.
Key features and highlights
- Deep integrations: an extensive library covering Google, HubSpot, Salesforce, and more.
- Conversation intelligence: automatic transcription and analysis on higher tiers.
- Established agency program: manager accounts and partner support built for scale.
Pricing
- Entry tier: per-month base plus usage.
- Higher tiers: add form tracking and conversation intelligence.
Ratings
- G2: 4.5/5
- Capterra: 4.5/5
When CallRail is not an ideal choice: costs can climb quickly once you multiply base fees and usage across a full client roster, which is exactly why “CallRail alternatives” is such a common search. See the full CallRail vs Nimbata breakdown.
Skip CallRail if: you want the same attribution at a leaner price with full white-label.
What are real users saying about CallRail?
What do you like best about CallRail?
I like how easy the UX is. It is very easy to find reports, especially working at an agency where we have multiple call rail accounts/numbers. The integrations with our reporting dashboard, Agency Analytics, is super helpful for our agency and clients. The speed/workload is never slow; performance from the account is superb. The pricing matches with what we receive on our agency account. CallRail support always gets back to my team almost instantly; there are never long wait times.
What do you dislike about CallRail?
I wish we could have individual clients’ cards associated with their accounts. Instead, we have our agency card that covers all numbers, and then we bill clients.
3. WhatConverts (Best for reporting-heavy agencies)
WhatConverts leans into lead tracking, not just call tracking. If your agency lives and dies by the monthly report, its lead-level reporting and dashboards are the selling point.
It captures calls, forms, and chats as unified “leads,” then lets you mark lead quality and value, which makes client reporting feel less like data and more like a story about revenue.
Key features and highlights
- Lead-level reporting: every call, form, and chat in one view, with quality and value fields.
- Flexible dashboards: client-ready reporting and scheduled sends.
- Solid attribution: keyword and source data across channels.
Pricing
- Entry tier: monthly base by lead volume (verify current pricing).
Ratings
- G2: 4.9/5
- Capterra: 4.9/5
When WhatConverts is not an ideal choice: if calls are your primary focus, you may pay for lead-management breadth you do not need. Compare them side by side in WhatConverts vs Nimbata.
Skip WhatConverts if: you want a call-first tool with heavier white-label and reselling built in.
What are real users saying about WhatConverts?
What do you like best about WhatConverts?
It does a good job simplifying the conversion tracking process. Setting up conversion tracking with whatconverts is easy, and I’m sure that every lead that comes in will be in one easy to find place for both our team members and for our clients. I feel comfortable using it every day for work, and we’re confident scaling it across our whole marketing agency.
What do you dislike about WhatConverts?
I have noticed that there are instances where WhatConverts can be a little buggy. But even then, the support team is super quick to respond and help you fix your issue.
4. CTM (Best for conversation analytics)
CallTrackingMetrics (now CTM) sits at the feature-rich end of the market, blending call tracking with call routing, scoring, and contact-center capabilities.
For agencies whose clients care about what happens on the call, not just that it happened, CTM’s conversation analytics and routing rules are the differentiator.
Key features and highlights
- Conversation analytics: call scoring, keyword spotting, and automation.
- Advanced routing: rules-based call flows and IVR.
- Broad integrations: connects to major ad and CRM platforms.
Pricing
- Entry tier: monthly base plus usage (verify current pricing).
Ratings
- G2: 4.5/5
- Capterra: 4.7/5
When CallTrackingMetrics is not an ideal choice: the depth adds a learning curve, and simpler agencies may not use half of it. See CallTrackingMetrics vs Nimbata for a lighter alternative.
Skip CallTrackingMetrics if: you want fast setup and a lighter tool your whole team can run day one.
What are real users saying about CallTrackingMetrics?
What do you like best about CTM?
I would say that their routing features have improved a lot in the recent years. Now setting up an IVR menu and smart routing makes it easy for the team members to get the right amount of calls.
We started using their speech to text transcriptions and keyword spotting. Instead of listening to audio for hours, we use the transcript scan.
What do you dislike about CTM?
Because costs are split across tracking numbers, minutes, texts and premium features, it’s a bit difficult to easily forecast or audit our monthly expenses.
For those managing multiple sub accounts or websites like us, pulling a single unified report is still a bit tedieous without constantly switching back and forth.
5. CallScaler (Best for freelancers and lean teams)
CallScaler is the value pick for solo marketers and small agencies who want tracking numbers and clean attribution without a per-seat spreadsheet giving them anxiety.
The appeal is flat, predictable pricing and generous number allowances, which suits a growing book of small clients.
Key features and highlights
- Flat, low pricing: predictable cost as you add numbers.
- Core attribution: DNI and source tracking that covers the essentials.
- Simple setup: live in minutes, not days.
Pricing
- Flat monthly plan: with included numbers.
Ratings
- G2: –
- Capterra: –
When CallScaler is not an ideal choice: reporting and integrations are lighter than the enterprise tools.
Skip CallScaler if: you need polished, fully branded client dashboards and deep CRM pushes.
6. Ringba (Best for pay-per-call agencies)
Ringba is built for performance and pay-per-call, where calls are the product and routing them to the right buyer in real time is the whole game.
If your agency runs pay-per-call campaigns or sells calls to advertisers, Ringba’s real-time routing and bidding are purpose-built. For standard lead-gen, it is more engine than most teams need.
Key features and highlights
- Real-time call routing and bidding: send each call to the highest-value destination.
- Granular analytics: deep call-level data for performance buyers.
- Ring tree and marketplace tools: for pay-per-call operations.
Pricing
- Usage-based: priced for performance volume).
Ratings
- G2: 4.9/5
- Capterra: 4.x9/5
When Ringba is not an ideal choice: it is overkill for agencies doing conventional lead attribution for local clients. See Ringba vs Nimbata.
Skip Ringba if: you just need to tell clients which campaign drove the call.
What are real users saying about Ringba?
What do you like best about Ringba?
Ringba makes our small team feel “bigger.” The routing function, reporting, and live analytics help our team manage campaigns without needing extra manpower. It’s reliable and makes it way easier to understand which ads or partnres are giving us the best return.
What do you dislike about Ringba?
It would be the initial learning phase to be familiar with the application. Some of the settings and routing options needs additional time to learn, especially when we were just getting started. Once I got used to the layout, it made sense, but those first few days took a bit of effort.
7. Infinity (Best for enterprise and global agencies)
Infinity is a call intelligence platform built for larger, often global agencies and brands that need enterprise-grade attribution and analytics across big ad budgets and multiple markets. If your clients operate at scale, Infinity is designed for exactly that.
The tradeoff is the usual enterprise one: more power, more setup, and pricing that only makes sense at volume.
Key features and highlights
- Enterprise call intelligence: conversation analytics and keyword-level attribution built for scale.
- Cross-market attribution: a strong fit for agencies running campaigns across regions.
- Robust integrations: connections to major ad, analytics, and CRM platforms.
Pricing
- Custom / enterprise: quote-based, at the premium end of the market.
Ratings
- G2: 4.6/5
- Capterra: 4.7/5
When Infinity is not an ideal choice: the price and setup are hard to justify for smaller agencies, which is why “Infinity alternatives” is a common search. See Infinity vs Nimbata for a lighter, white-label option.
Skip Infinity if: you are an SMB-focused agency that wants simple, affordable white-label.
What are real users saying about Infinity?
What do you like best about Infinity Call Tracking?
The core product of Infinity Core Tracking works well. It is able to tell us from which of our sources the call originated, so we can distinguish between Paid Search, Organic Traffic, and emails. This attribution is helpful for working out which channels have resulted in contacts.
Customer support has always come through with an answer when we’ve had questions.
What do you dislike about Infinity Call Tracking?
The interface looks like it was last updated 10 years ago. The help documentation is confusing and poor in parts, and the integrations with third-party services are tricky to set up. More investment in the customer journey would be good.
Customer support may be good, but the flipside is we’ve had to ask about a bunch of stuff that we’d expect to self-serve, because the docs are unclear or out of date.
Who Should Pick Which Tool
| App | Best for this agency type | Standout reason | Skip it if |
|---|---|---|---|
| Nimbata | Most agencies wanting white-label value | Own the brand, resell the margin | You need a full phone system |
| CallRail | Large, multi-service agencies | Name recognition + integrations | Budget matters at scale |
| WhatConverts | Reporting-first agencies | Lead-level reporting | Calls are your only focus |
| CallTrackingMetrics | Analytics-driven teams | Conversation intelligence | You want simple and fast |
| CallScaler | Freelancers and small shops | Flat, low pricing | You need deep reporting |
| Ringba | Pay-per-call operators | Real-time routing and bidding | You do standard lead-gen |
| Infinity | Enterprise and global agencies | Enterprise call intelligence at scale | You are an SMB-focused or budget agency |
Ready to turn calls into a service you own?
If you run one or two small clients, almost any tool on this list will do the job. Be honest with yourself about that.
But the moment you are juggling a real roster, the math changes. You need one login for every client, reports that wear your brand, attribution a client cannot argue with, and pricing that does not punish you for winning more business. That is the gap Nimbata was built to close: full white-label, per-client workspaces, keyword-level attribution that pushes straight into Google Ads and GA4, and a partner program that lets call tracking become margin instead of overhead.

Frequently Asked Questions about Call Tracking for Agencies
For most agencies, Nimbata offers the best mix of white-label branding, per-client management, attribution depth, and price. CallRail is the strongest pick for large multi-service agencies that value name recognition and integrations, while WhatConverts suits reporting-heavy teams. The “best” choice depends on your client count, your need for white-label, and your budget per client.
White-label call tracking lets an agency present the platform as its own: your logo, your colors, your domain, and client logins that never show the vendor’s name. It turns call tracking into a branded service you can resell, rather than a third-party tool your clients see and could go buy directly.
Yes. Tools with a partner or agency program (like Nimbata) let you buy at agency rates and resell to clients at your price, keeping the margin. Combined with white-label, this is how many agencies turn call tracking into a recurring revenue line instead of a pass-through cost.
It varies by platform and usage. Most tools charge a monthly platform fee plus per-number and per-minute usage, and agency or partner plans add volume discounts for reselling. Nimbata is the only call tracking software that charges per call and not per minute.
Before starting a new trial, confirm current tiers on each vendor’s pricing page, and model the cost at your tenth client, not your first, since that is where plans differ most.
CallRail offers agency features and manager accounts, and it is a mature option for larger agencies. White-label capabilities and pricing differ from purpose-built agency tools, so if full branding and reselling margin are priorities, compare it directly against a white-label-first platform before deciding.
For freelancers and lean teams, CallScaler’s flat pricing is a strong value pick, and Nimbata’s entry plan is a good step up when you want white-label reports and deeper attribution as you add clients.
Most agency-grade platforms are paid, because tracking numbers carry real per-number and per-minute phone costs. That said, many tools (including Nimbata) offer a free trial so you can test the workflow on a client account before committing. Be cautious with fully free tools, since attribution accuracy, reporting, and white-label are usually limited.
Regular call tracking is built for one business. Agency call tracking adds multi-client management from one login, white-label branding, client-ready reporting, and reselling or partner pricing, so you can run and monetize attribution across an entire roster without logging in and out or exposing the vendor’s brand to your clients.
