The cheapest agency sub-account plan is $89 — but its minute costs two and a half times CTM's

If you’re an agency, the words “agency tier” hide two completely different pricing philosophies, and picking the wrong one can cost you several hundred dollars a month. The cheapest published plan that packages client accounts at all is WildJar’s Growth/Agency tier at $89/mo month-to-month, which lists unlimited client accounts, a whitelabel dashboard and reseller margin on usage. The cheapest plan that packages a counted number of them is CallTrackingMetrics Marketing Pro at $179/mo month-to-month (~$149/mo billed annually), with 25 sub-accounts and extra packs of 25 at $50/mo. The $79 Marketing Lite plan below it — the one that looks like the obvious agency entry point — includes no sub-accounts at all. And the ladder that advertises the phrase loudest, WhatConverts’ “Unlimited Accounts” tiers, starts at $500/mo and climbs to $800 and $1,250. Four prices for what sounds like one product, and the difference between them is not the base — it is what the meter does after you sign.

$89, $179, $500: the base is the smallest part

WildJar’s $89 is a platform fee, and a thin one. Usage sits entirely on top of it, and it is the most expensive usage in this dataset: $0.10 per call minute, $8.50/mo per local tracking number, $0.06 per SMS, and $0.04/min for its AI transcription. There is no annual billing to soften any of it — the words annual, yearly and per year appear nowhere on WildJar’s pricing page, and its FAQ states monthly subscriptions only, billed in arrears, cancellable on 30 days’ notice. Give each of twenty-five clients a single tracking number and you are paying $212.50/mo in numbers alone before a minute is metered — more than CallTrackingMetrics’ entire Marketing Pro base. (CTM publishes no per-number price in our dataset, so that particular line can’t be compared across the two. The minute can.)

Marketing Pro is priced per platform, not per client. Twenty-five sub-accounts and white-labelling sit inside that one $179 base, and usage is metered on top: local call forwarding is a single platform-wide $0.04/min across Marketing Lite, Marketing Pro and Sales Engage, and transcription runs $0.02/min once you are past the 3,000 transcribed minutes each sub-account gets — minutes CTM states do not renew month to month, so treat them as a one-off allowance rather than a recurring bundle. Annual billing brings Marketing Pro to roughly $149/mo (~17% off), and CTM publishes a two-year rate worth about 24% off.

Marketing Lite is the tier to be careful with. Its $79 buys unlimited users and unlimited tracking sources, which reads like an agency plan and is priced like one — but the sub-account grid gives it none. If you manage clients in separate accounts, $79 does not buy that job at any volume.

WhatConverts inverts the model again. Its standard single-account plans — $30 / $60 / $100 / $160, with no annual rate published — aren’t built for managing many clients; the multi-client product is a separate ladder of $500 / $800 / $1,250 “Unlimited Accounts” tiers. Part of what that premium buys is a cheaper marginal minute: WhatConverts’ overage on the regular plans is $0.045/min local, and the agency tiers cut it to $0.04/min. Note where that lands — $0.04/min is exactly what CTM charges for local forwarding on every one of its tiers. Against CTM, the marginal-minute half of the $500 pitch is worth nothing; it is a discount against WhatConverts’ own plans.

CTM Marketing Pro	$179 m-t-m (~$149 annual)	25 sub-accounts, +25 packs at $50/mo, white-label	$0.04/min; $0.02/min transcription past a non-renewing 3,000 min per sub-account
CTM Sales Engage	$329 m-t-m (~$274 annual)	unlimited sub-accounts	$0.04/min; VoiceAI $0.12/min past 60 min per agent

The break-even is minutes first, client count second

Two numbers decide this, and the sticker is neither of them.

The first is minutes. WildJar’s base undercuts CTM Marketing Pro by $90/mo and its minute costs $0.06 more, so Marketing Pro is the cheaper bill from about 1,500 tracked minutes a month ($90 ÷ $0.06) across all your clients — twenty-five clients averaging one hour of tracked calls each land exactly on that line. That crossover counts base and minutes only — WildJar’s $8.50 per number has no published CTM counterpart to stand against, and folding it in would move the line earlier, in CTM’s favour, not later. Against CTM’s unlimited tier the base gap is $240/mo, so Sales Engage at $329 overtakes WildJar at about 4,000 minutes. Against WhatConverts’ $500 entry the same arithmetic runs much longer — $411 ÷ $0.06 is roughly 6,850 minutes — which is another way of saying WhatConverts’ agency ladder isn’t competing on price with either of them.

The second is client count, and it lands entirely inside CTM’s own ladder. Up to 25 accounts, Marketing Pro at $179 is the cheapest counted bundle here. Past 25 you can add packs of 25 at $50/mo — but three packs put Marketing Pro at exactly $329/mo, which is the price of Sales Engage, whose sub-accounts are unlimited. The packs stop making sense at 100 clients, and above that CTM’s unlimited tier costs $329/mo month-to-month (~$274 billed annually) — $171/mo less than WhatConverts’ cheapest unlimited plan. If “unlimited client accounts” is the thing you are shopping for, the two cheapest on this board are WildJar’s $89 and CTM’s $329, and neither is the $500 tier that advertises the phrase.

Inside WhatConverts’ own range, the marginal-minute case is close to hopeless: stepping from Elite at $160 to the entry agency tier at $500 costs $340/mo, and at a half-cent saved per minute you would need roughly 68,000 local minutes a month before the discount alone covered it.

One caveat runs the other way. CTM’s next step above Sales Engage is Enterprise at $1,999/mo, so an agency that outgrows Sales Engage on some axis other than account count — professional services, dedicated account management — faces a cliff, whereas WhatConverts’ agency ladder steps up to $800 and then $1,250. That is a different purchase from sub-account headroom, but it is why the two ladders are not simply substitutes.

The other “Agency”-labelled plans publish no structure at all

Two more vendors here attach the word “Agency” to a tier without publishing anything behind it about client accounts: Convirza’s Agency tier at $149/mo at $0.05/min plus $1.00 per number — a list price rather than a checkout, since every tier’s button on that page reads “Get A Demo” — and Nimbata’s Agency plan at $149/mo month-to-month ($120/mo billed annually). In both cases the “Agency” branding marks a usage and feature tier, not a packaged client container. Nimbata’s is the hardest to line up at all: it bills per answered call rather than per minute, and the per-call rate isn’t published, so it can’t be compared on the same axis as anything else on this page.

If you ignore the label and just hunt for the lowest base price, the cheapest entries sit well under $89 — Dialics at $0 (pure pay-as-you-go at $0.045/min inbound local), Convirza Starter at $29, WhatConverts at $30, Nimbata Pro at $39 month-to-month ($35 billed annually), CallRail at $55 month-to-month ($50 billed annually) and CTM’s own Marketing Lite at $79 — and not one of them publishes a client-account container. CallRail, the most-integrated platform here (700+ native integrations), bundles 250 local minutes and 5 numbers into that $55 and meters at $0.06/min beyond them, but carries no sub-account allotment in this dataset. For a single client, most of those plans beat every agency tier on this page comfortably; for an agency that needs client accounts, they answer a different question.

How to read this

Two plans are worth shortlisting, and choosing between them is a minutes question rather than a sticker one. WildJar’s Growth/Agency plan at $89/mo month-to-month is the cheapest published multi-client container — unlimited client accounts, whitelabel dashboard, reseller margin — and it stays cheapest only while your tracked volume is low, because its $0.10 minute and $8.50 number are the most expensive metered rates on this board. CallTrackingMetrics Marketing Pro at $179/mo month-to-month (~$149 billed annually) is the cheaper bill from roughly 1,500 tracked minutes a month, and it is the only plan here that publishes an actual number of client accounts — 25, with packs of 25 at $50/mo — rather than the word “unlimited”. Past 100 clients, or if you would rather buy headroom than do arithmetic, CTM Sales Engage at $329/mo (~$274 annually) is the cheapest unlimited-account plan with a four-cent minute under it, $171/mo below WhatConverts’ $500. And whatever you do, don’t read CTM Marketing Lite’s $79 as the agency entry point: it includes no sub-accounts at all. Count your clients, then count your minutes — on this board the meter decides more than the sticker does.
