Ringba vs Retreaver vs Invoca Call Tracking: What Each Really Costs

TL;DR

• Two of the three publish per-minute rates, but only one puts them on its pricing page. Ringba lists a full rate card publicly (ringba.com/pricing). Retreaver publishes rates too, buried in its documentation rather than its marketing site (learn.retreaver.com).
• Invoca publishes no dollar figure anywhere. Its pricing page names plans and entitlements, then routes every tier to a “Get Your Quote” form (invoca.com/pricing).
• The tidy “three platforms for three business models” split that most comparisons sell does not survive a read of the vendors’ own sites. Ringba and Retreaver both advertise real-time bidding, and Invoca publishes dedicated pay-per-call plans.
• The cheapest platform at moderate volume is not the one with the lowest per minute rate. Retreaver charges no mandatory monthly platform fee and $1 per number per month, while Ringba charges $147 to $297 a month plus $2 to $4 per number. On 10,000 tracked local minutes and 20 numbers that is about $520 a month against about $757.

Most comparisons of these three platforms rank them on features. That is the least useful axis, because the feature lists overlap heavily and every vendor claims the same capabilities. The differences that will actually shape your economics are pricing transparency, billing model, and what each platform charges for on top of the headline rate. Two of those you can check yourself in about ten minutes, which is what this page does.

The Three Platforms Side by Side, on the Numbers Each One Publishes

Every figure below was read on the vendor’s own pricing page on 10 August 2026. Where a cell says “not published”, that is the finding, not a gap in our research: it is the single most useful thing this comparison can tell you before you book a demo.

Key Concept: Two of these vendors let you build a budget from a public page. One does not. That is not a small procurement detail. It decides whether you can size the cost of a channel before you commit a salesperson’s calendar to finding out.

The Neat Three-Way Split Most Comparisons Sell Is Not What the Vendors Say About Themselves

Nearly every published comparison of these platforms assigns each one a lane. Ringba gets publishers and networks, Invoca gets enterprise buyers with their own sales floors, and Retreaver gets the agencies in the middle. It is a clean story, and it is easy to write without opening a single vendor page.

Read the three sites and the lanes blur immediately.

Retreaver sells real-time bidding, and does not charge extra for it. Its homepage lists RTB alongside its Tag, Track, Route model, and names its audience as “Publishers, Networks, and Advertisers” (retreaver.com). Its own documentation goes further, listing real-time bidding under what it does not charge for: “There is no additional charge for using real-time bidding.” Auction routing is not territory Ringba holds by itself.

Ringba sells to agencies, and gates its auction tools by tier. Its homepage describes the platform as built for “digital agencies, pay per callers, and global brands”, and its Ring Tree product promises to “Sell your calls to the highest bidder with our automated RTB technology” (ringba.com/ping-tree). Worth knowing before you pick a plan: on the pricing page, Real-Time Bidding and Ping/Post Call Trading are listed as enterprise-tier line items, and the Professional plan includes five Ring Tree setups a month with additional ones at $100 each.

Invoca sells pay-per-call plans. Alongside Pro, Enterprise and Elite, Invoca publishes plans named Performance Professional and Performance Enterprise, described as being for pay-per-call and affiliate marketing (invoca.com/pricing). The idea that Invoca has nothing for the sell side is something comparison writers repeat, not something Invoca says.

What Each Vendor Publicly Claims to Sell

Sources: ringba.com, retreaver.com/features and invoca.com/pricing, all read 5 August 2026. Quoted phrases are the vendors’ own words.

Two of the Three Publish Rates, and One of Them Hides Them in the Docs

This is the most practically useful difference between the platforms, and almost no comparison leads with it.

Ringba puts its full rate card on a public pricing page: plan fees, per-minute tracking, recording and transcription rates, number rental, and per-lookup charges. Retreaver publishes nothing on its marketing site, and its homepage does not even contain the word pricing. Its documentation, however, does publish rates, and on a completely different commercial model. Invoca publishes no dollar figure at all.

Ringba’s Published Rate Card

All figures as published at ringba.com/pricing and re-read on 12 August 2026, when every rate above was unchanged. Voice Agents are listed at $0.05 per minute across tiers, and the same page states there are no contracts or setup fees. Rate cards change without notice, so check before you budget.

Key Concept: The plan fee is not the bill. On Ringba’s Business tier the meter passes the $147 plan fee at 1,400 tracked local minutes a month, once recording and transcription are switched on. A comparison that ranks these platforms on the plan fee is ranking the smallest line on the invoice.

What the Directories Say the Plan Fee Is, and What Ringba Says

This is the one number a buyer can check in about thirty seconds, and the pages that rank for this comparison mostly carry a different one. SpotSaas, in its three-way comparison of CallTrackingMetrics, Invoca and Ringba, lists Ringba at “$99 /Month”. Ringba’s own pricing page, read the same day, publishes $147 per month billed monthly for Business, or $127 per month billed annually at $1,524 a year. Professional is $297 billed monthly, $197 billed annually at $2,364 a year.

Both figures are real. They are not the same figure. The vendor’s number is about one and a half times the aggregator’s, a $48 gap on the entry plan before a single minute is tracked. The point is not that the directory is dishonest. The point is that the directory row carries no date and the vendor’s page has to stay current, so a budget built on the first one starts low. Read the page belonging to the company that has to honour the number.

Where the Plan Fee Stops Being the Big Number

Do the arithmetic once and the shape of the invoice stops being a surprise. Take a buyer on Ringba Business. They take 2,000 calls a month averaging two and a half minutes, so 5,000 tracked local minutes. Recording and transcription are switched on. They pull one Instant Caller Profile per call, and rent a pool of 25 local numbers. Every rate below is Ringba’s own published figure.

Arithmetic on the rates published at ringba.com/pricing, read 12 August 2026. It is a worked example on published rates, not a quote, and not anyone’s actual bill.

The plan fee is 14% of that invoice. The other 86% is metered, and it scales with the exact thing you are trying to grow. The crossover arrives earlier than most buyers expect. Tracking, recording and transcription together cost $0.105 a minute on Business, so the meter matches the $147 plan fee at 1,400 minutes a month. That is one busy campaign, not a scaled operation.

Change the assumptions and the ratio moves. The direction does not. That is why the plan fee is the wrong field to compare vendors on. A directory row holding one price and no unit rates cannot answer the question a buyer is actually asking.

Retreaver’s Rates Are Published, Just Not Where You Would Look

Retreaver’s marketing site has no pricing page, and requests for one return a 404. Its documentation carries the numbers instead, on a page last dated 18 March 2026, and the model is materially different from Ringba’s.

There is no plan fee. Retreaver describes “a flexible, pay-as-you-go pricing model with no monthly subscription fees or long-term contracts”, with call usage “Starting at $0.05/min” and phone numbers at “$1/number/month”. It also publishes a short list of things it does not bill for, which includes real-time bidding and dropped calls. Rates “may vary depending on volume”, so treat the published figure as a starting point rather than a quote.

That difference matters most at low volume. A Ringba Professional subscription costs $297 a month before a single minute is tracked, whereas Retreaver’s published model starts billing at the first minute. At high volume the plan fee stops being the deciding factor and the per-minute rate, the add-on charges and your negotiated discount take over.

Invoca Publishes Entitlements, Not Prices

Invoca’s pricing page contains no dollar figure anywhere. What it does publish is the shape of each plan: Pro includes 6,000 annual local or toll-free numbers and 5 custom Signals, Enterprise includes 12,000 numbers and 50 Signals, and Elite includes 18,000 numbers and 100 Signals. Signals are Invoca’s term for the custom call outcomes its AI detects.

Every tier ends at the same place, a “Get Your Quote” form explaining that “Invoca’s pricing is based on a few specific factors” before a meeting is arranged. Any per-call Invoca price you see in a comparison article is therefore either one customer’s negotiated contract or an invention, and you have no way to tell which.

The Headline Per-Minute Rate Is Not the Rate You Pay

Here is the part that catches people out, and you can work it out from Ringba’s own published figures rather than taking anybody’s word for it. The advertised tracking rate covers tracking. Recording and transcription are separate line items, and most pay-per-call operations want both, because that is how you audit call quality and settle disputes with buyers.

Arithmetic on the rates published at ringba.com/pricing, read 5 August 2026. Your actual bill depends on your call mix, your number count and your contract.

On the Business plan, turning on recording and transcription takes the per-minute cost from $0.055 to $0.105, a little under double. On Professional it moves from $0.05 to $0.09. Neither figure is hidden and neither is a trick. They simply sit on a different row of the same page from the number that ends up in most comparison articles, and a budget built on the headline rate alone will come in low. Ringba’s own page adds that summarization, sentiment analysis and conversion detection “may incur additional costs” on top of transcription.

Note too that Professional costs $150 more per month than Business while discounting every per-minute line. Where the crossover sits depends entirely on your minute volume, which is arithmetic you can do yourself from the table above before anyone quotes you anything.

What to Ask Before You Sign

Published rates are a starting point, not a quote. Ringba’s rate card is a useful template precisely because it enumerates the things that generate charges, so take its line items to whichever vendors you are talking to and ask for each one.

Ask for the unit, not the bundle. A monthly figure with “up to X minutes included” is not comparable to a per-minute rate until you know the overage charge and what happens to unused volume.

• Billing increment and rounding. Per second, per six seconds, or per minute rounded up? On short calls this changes the effective rate substantially, and it is rarely volunteered.
• Recording and transcription. Bundled or metered? At what rate, and is transcription charged on every call or only on ones you flag? Ask what the analysis layers on top of transcription cost.
• Number rental. Monthly cost per local and per toll free number, and whether there is a minimum pool size.
• Bidding and routing fees. Whether real-time bidding, ping trees or buyer integrations carry any charge, and on which tier they become available. Ringba lists RTB and ping/post as enterprise features, and prices extra Ring Trees separately. Retreaver says RTB carries no extra charge.
• Dropped and unanswered calls. Whether you are billed for them. Retreaver publishes that you are not, and it is worth making the others answer the same question.
• Data lookups and enrichment. Ringba prices caller profile pulls per lookup. Ask the others whether equivalent enrichment is metered.
• Minimum commitment and term. Annual lock-in, monthly minimum spend, and what the exit looks like.

Get the answers in writing before the demo impresses you. A vendor that will not put unit rates in an email is telling you something about how the renewal conversation is going to go.

How to Choose When the Feature Sets Overlap

Since all three route calls and at least two run auctions, the decision comes down to less glamorous things.

Choose on cost structure if your margin is thin. If you resell calls, platform cost sits directly between your buyer payout and your traffic cost. The real question is whether a monthly plan fee suits your volume. Ringba charges one and publishes exactly what you get for it. Retreaver’s published model does not, which favours a smaller or spikier operation, though you still have to ask for a quote to confirm what applies to you. Either way you are building a ping tree or buyer distribution layer, and both vendors sell one.

Quick Win: Ringba’s own two published tiers cross over at about 26,000 tracked local minutes a month. Professional costs $150 more per month than Business, and earns it back at $0.005 per minute on tracking plus $1 per number. Below roughly 26,000 minutes on a 20 number pool, the cheaper plan is the better plan, and the upgrade prompt is worth ignoring. Run the arithmetic on your own minute count before a salesperson runs it for you.

Choose on conversation intelligence if the call content is the product. Invoca’s plans are organised around Signals, and its Signal AI page describes models “trained on your business’s calls that capture the intent, product/service interest, and conversion outcome of every conversation”. If your reason for buying is scoring what was said and feeding that into your ad platforms and CRM, that is the product line built around it. Invoca has been building this since it acquired DialogTech in May 2021. Note that its Google Ads and Facebook pages describe sending call conversion data in for bidding and audience building rather than a formal offline conversion import, so confirm the exact mechanism against your own setup.

Choose on operational fit if you run many campaigns at once. Retreaver’s tag-based routing attaches data to calls and routes on any attribute, which suits a book of business where each client or vertical has different qualification logic. Its SkipThrough IVR asks only the questions still needed for the buyers actually available, and Retreaver Rescue redirects a call to the next buyer when one hangs up. Both matter when unanswered calls are lost revenue rather than a retry.

Where the Rest of the Shortlist Fits

Buyers rarely stop at three names. Here is the short answer on the three that come up next, with the subject of this comparison unchanged.

CallRail is an attribution product for businesses that take calls, not a distribution layer for businesses that sell them. It has no auction and no buyer routing, which is most of the job on this page. The long answer is in our guide to CallRail alternatives for pay-per-call, and the upgrade decision itself in stay or switch.

CallTrackingMetrics sits between the two camps, with more routing and form handling than CallRail and less pay-per-call machinery than Ringba. It is the third name on the directory comparison that ranks for this query. Its pricing page builds its plan tiles in the browser rather than the page source. We are not repeating a figure we could not read at the vendor first-hand.

TrackDrive is the closest structural comparison to Ringba, and it prices the opposite way round. There is no plan fee at all. Its published card charges pay-as-you-go rates of $0.0550 a minute for local tracking, $0.0600 for toll free, $0.0350 for AI transcription and $4.00 a month for numbers. Every one of those rates falls as you commit to a larger monthly spend, on a ladder running from $50 to $8,000 (trackdrive.com/pricing, read 12 August 2026). Look at the entry rate. All three published cards in this category put entry local tracking between $0.05 and $0.055 a minute: Retreaver at $0.05, Ringba Business at $0.055, TrackDrive pay-as-you-go at $0.0550. The meter is close to a market rate. What actually differs between these vendors is the plan fee wrapped around it, which is both the line the directories compare and the smaller of the two.

Do not choose on a comparison chart, including this one. Run the same test traffic through a trial on your shortlist and read your own logs.

What This Comparison Does Not Tell You

Invoca publishes no prices, and the two vendors that do both qualify their numbers, so no honest article can rank all three on cost. Anyone who does has either been quoted personally, which is not your quote, or has made the numbers up.

We also cannot tell you what any of them will charge you. Published rates are starting points that move with volume, term and negotiation. Feature lists tell you what a vendor sells, not how well it works at your call volume, and that only shows up in a trial.

Be careful with the third-party directories too. As the plan-fee section above shows, the aggregator row and the vendor’s own page differ by roughly 50% on the one number everyone quotes. Only one of the two carries a date. Read the vendor’s page, not the aggregator’s cache.

Finally, the qualifying-call threshold that governs your revenue, the number of seconds before a connect becomes billable, is not an industry constant. Retreaver’s own documentation uses 30 seconds, 90 seconds and two minutes as examples on a single page, and Ringba exposes it as a configurable field with no default. Your buyers and your contracts set that number, so pin it down with them first. It is the input every cost model here depends on.

Frequently Asked Questions

Does Ringba publish its pricing publicly?

Yes, and it is the only one of the three with a public pricing page. Ringba lists plan fees of $147 per month for Business and $297 per month for Professional when billed monthly, dropping to $127 and $197 when billed annually. The same page publishes per-minute rates for tracking, recording and transcription, monthly costs for local and toll free numbers, and a per-pull charge for caller profile lookups, and states there are no contracts or setup fees. Enterprise is custom. All figures were read at ringba.com/pricing on 5 August 2026, and rate cards change, so confirm before budgeting.

How much does Retreaver cost?

Retreaver has no pricing page on its marketing site, but it does publish rates in its documentation. As of a page dated 18 March 2026, it describes a pay-as-you-go model with no monthly subscription fees or long-term contracts, call usage starting at $0.05 per minute, and phone numbers at $1 per number per month. It also states it does not charge extra for real-time bidding and does not bill for dropped calls. Rates vary with volume, so treat those as a floor and ask for a quote covering your billing increment and any analysis add-ons.

How much does Invoca cost?

Invoca is quote-only and publishes no dollar figure anywhere on its pricing page. It names plans called Pro, Enterprise, Elite, Performance Professional and Performance Enterprise, and quantifies entitlements rather than price: 6,000 annual numbers and 5 custom Signals on Pro, 12,000 and 50 on Enterprise, and 18,000 and 100 on Elite. Every tier routes to a “Get Your Quote” form stating that pricing depends on specific factors. Treat any per-call Invoca price quoted in a comparison article as unsourced unless it names the customer and the contract.

Is Invoca only for enterprise buyers with their own sales floors?

No, and this is a common error in comparison content. Invoca publishes two plans named Performance Professional and Performance Enterprise that it describes as being for pay-per-call and affiliate marketing, which is sell-side territory. Its conversation intelligence is genuinely aimed at organisations that own the conversion event, so the fit is stronger if you run your own closer floor and control the bidding. But the claim that Invoca offers nothing to publishers and networks is contradicted by its own pricing page.

Does only Ringba offer real-time bidding?

No. Ringba’s Ring Tree product advertises selling calls to the highest bidder through automated RTB, and Retreaver lists real-time bidding on its homepage and states in its documentation that it carries no additional charge. Both vendors advertise auction-based routing in their own words. Ringba does gate it commercially, listing real-time bidding and ping/post call trading as enterprise-tier items on its pricing page, so check which plan actually includes what you need rather than assuming the capability is included.

Is CallRail a real alternative for pay-per-call operators?

CallRail is built for a different job. It is attribution software for businesses tracking inbound calls from their own marketing, which is a genuinely different problem from routing calls to a marketplace of buyers and reconciling payouts. If your requirement is buyer auctions, publisher payout and duration-based settlement, that is not the category CallRail competes in. We cover the trade-offs in more detail in our guide to CallRail alternatives for pay-per-call.

What should I test during a trial of a call tracking platform?

Route real traffic rather than test calls, because routing logic behaves differently under concurrency. Confirm that the platform records the billable duration exactly the way your buyer contracts define it, since that number settles your invoices. Check that call data reaches your reporting and your buyers in the format you need, and time how long a routing change takes to build, because that is a cost you pay every week rather than once. Finally, export your data during the trial and confirm you can get it out cleanly.

Bring Us the Quote Before You Sign It

Choosing a call tracking platform is mostly a procurement problem wearing a technology costume. The capabilities overlap, published prices are starting points at best, and the difference between a good deal and a bad one shows up in billing increments and contract terms rather than on a feature chart. Elevarus buys and sells calls for a living across home services and insurance, so if you want a second opinion on a quote you have been given, book a free strategy call and bring the numbers.
