Nine of the fourteen Amazon PPC tools in this post charge a percentage of ad spend somewhere in their line-up: Advigator, Scale Insights, Helium 10, m19, Adbrew, Teikametrics, Perpetua, BidX, and Ad Badger. Three publish no percentage anywhere I could find a price — Sellozo, Zon.Tools, and Jarvio. Two publish no pricing at all — Intentwise and Entourage. AdsPlane, which publishes this post, is flat monthly at every tier and never a percentage of spend.
That headline count hides the detail that actually matters, though. For most of these vendors the percentage does not apply to the whole product line — it sits on one specific tier or one specific product. Ad Badger's percentage belongs to its managed service, not to any of its six flat software plans. Teikametrics' 3% belongs to its two upper tiers, not to its $149/month entry plan. Getting this wrong is the single most common error in "which tools charge a percentage" articles, and it is why this post names the tier or product beside every figure.
Every competitor figure below was read off the vendor's own live pricing page on 19 July 2026. Where a vendor states that it charges a percentage but does not publish the rate, this post says "not published" rather than filling the gap — three vendors are in that position, and knowing which three is itself useful. Prices change without notice; if you are reading this much later, treat it as a snapshot and re-check before you buy.
I run my own Amazon brand and built AdsPlane to manage it, so this is not a neutral survey. It is a practitioner's price audit, published by a vendor with an obvious preference for one of these models. I have tried to earn the benefit of the doubt by quoting each vendor's own wording, naming the tier every number belongs to, and being explicit about what I could not find out.
The six pricing models in this market
Grouping by "how much does it cost" is useless here, because the answer depends on your spend for half these vendors. Grouping by how the bill is constructed is what actually separates them:
- Pure percentage of ad spend — no flat fee at all. Your entire bill is a share of what you spend.
- Flat base plus a percentage — a subscription fee with a percentage stacked on top.
- Greater of a flat floor or a percentage — you pay whichever is larger, never both added together.
- Flat, with a separate percentage plan offered as an alternative — two ways to buy the same software, and you pick one.
- Spend-bracketed flat subscription — the price rises as your spend crosses thresholds, but within each bracket it is a fixed dollar amount, not a percentage.
- Flat monthly, per-ASIN, or per-marketplace — the bill does not move when your spend does.
That fifth one is the subtle one. A spend-bracketed subscription scales with spend without being a percentage of spend, and the difference is real: at Zon.Tools' $25,001–$50,000 bracket, the Dominator plan is a fixed $949/month whether the account spends $26,000 or $49,000. Calling that "percentage pricing" would be wrong.
Where a vendor sells two products at two different models, it appears in both groups below, with the product named.
Pure percentage of ad spend, no flat fee
| Vendor | What's charged | Source, read 19 Jul 2026 |
|---|---|---|
| Advigator | Graduated percentage of the ad spend it manages, with no fixed fee of any kind: 5% on the first €30K/month, 3% on the portion between €30K and €200K, 2% above €200K/month. Rates are marginal, so the effective rate always lands between 2% and 5%. | advigator.com/pricing |
Advigator is the only vendor here with no subscription component whatsoever. Its page states "No fixed fees. Pay only for campaigns we run, only while they're live," along with "No minimum fee, no minimum budget" and "Campaigns paused? You pay €0 that month."
The bands are marginal, like income-tax brackets — not three plans you choose between. The vendor's own worked example makes this explicit: €50,000 of monthly ad spend costs €30K × 5% + €20K × 3% = €2,100, which the page calls "an effective rate of 4.2%, not 3% or 5% flat." So there is no "5% tier" to sign up for.
Two qualifiers worth keeping. First, the fee base is "the ad spend it manages" — campaigns under Advigator's control, not your total Amazon ad spend. Dropping that qualifier overstates the cost. Second, Advigator prices in euros and publishes no USD list ("Prices are in EUR (€)"), so there is no honest way to line its numbers up against a dollar-priced tool without inventing an exchange rate. I have not attempted it.
Flat base plus a percentage, on at least one tier
This is the largest group, and the one where tier detail matters most.
| Vendor | Which tier carries the percentage | The rate | Source, read 19 Jul 2026 |
|---|---|---|---|
| Helium 10 | A "Managed spend fee" shown on the Diamond tier ($359/month month-to-month, $279/month billed yearly). Platinum is $129/$99 and Enterprise is listed at $1,499/month as a "Starting Price. Billed Annually." | 2% | helium10.com/pricing |
| m19 | m19 Professional only, at 400€/month or $479/month plus the percentage, "Of total Ads spend, excl. VAT, per Month." The entry Autopilot plan is 49€/$59 per month flat with no percentage. | 3% | m19.com/pricing-automated-ppc-campaigns |
| Teikametrics | Advanced and Enterprise only, both of which show "Custom Pricing" as the base — so the total cannot be computed from the page. Essentials, for accounts up to $10K/month spend, is $149/month billed annually or $179/month billed monthly, with no percentage. | "+3% of ad spend over $10K" | teikametrics.com/pricing |
| Perpetua | Growth only, at "$695 /mth + % of ad spend," for accounts over 10k in monthly ad spend. Essentials is the same $695/mth with no percentage, for accounts up to 10k. Premium is "Custom." | Not published | perpetua.io/pricing |
| BidX | Every platform tier, self-serve and managed alike: Amazon PPC at 495€, 1.995€ and 4.995€ per month, and Amazon DSP at €495 and €995 per month, each followed by "+ % of connected ad spend per month." All plans are on an annual commitment with monthly payments. | Not published | bidx.io/en/pricing |
| Ad Badger — managed service only | Ad Badger's PPC management service, not its software. "Base Fee: Just $975" plus "A mere 8% of your ad spend," subject to "a minimum engagement fee of $2500 per month." Its six software plans carry no percentage — see the spend-bracketed section below. | 8% | adbadger.com/amazon-ppc-management-services |
A few notes on reading that table honestly.
Helium 10's other percentages are not ad-spend fees. The 10% and 15% figures elsewhere on its pricing page belong to a "Managed refund service" under an Operations heading — a share of recovered reimbursements, not of ad spend. Only the 2% sits under Advertising & Marketing. Separately, one of my extraction passes read the 2% as appearing in the Platinum column too, while the raw table render put it in Diamond alone; I have gone with the raw render, and this is a good example of a claim worth eyeballing yourself before you rely on it.
Perpetua's $695 is not the differentiator between its two lower tiers. Both Essentials and Growth show the identical "$695 /mth" price string. What separates them is the ad-spend bracket and the fact that only Growth carries the percentage. So "Perpetua's entry plan is $695 plus a percentage" would be wrong — the entry plan has no percentage.
BidX's European decimal notation trips people up. "1.995€" and "4.995€" use the period as a thousands separator: they are €1,995 and €4,995 per month, not two euros. The same page confirms the convention elsewhere with "Less than 10.000€ monthly ad spend."
Ad Badger's two products must not be blended. The $975 base fee and the 8% belong exclusively to the managed service and never to any of the six named software tiers. Note also that the $975 carries no stated billing period on the page — only the 8% and the $2,500 minimum are period-qualified — so I have not written it as "$975/month."
Greater of a flat floor or a percentage
| Vendor | What's charged | Source, read 19 Jul 2026 |
|---|---|---|
| Adbrew | Standard plan: "$799/month or % of ad spend, whichever is greater," for accounts with monthly ad spend up to USD 500K. Enterprise, above USD 500K/month, is "Custom." | adbrew.io/pricing |
This is a structurally distinct model and worth separating out. The $799 is a floor, and the percentage is an alternative basis that applies only when it exceeds the floor. The two are never summed, so "$799/month plus a percentage" would misstate it in the vendor's disfavour.
The rate itself is not published. The page prints a bare "%" with no digit anywhere on it. Any specific Adbrew percentage you see quoted elsewhere did not come from that page.
Flat, with a separate percentage plan as an alternative
| Vendor | What's charged | Source, read 19 Jul 2026 |
|---|---|---|
| Scale Insights | Two ways to buy, offered side by side. A seven-step per-ASIN flat ladder from $78/month (5 automated ASINs) to $688/month (100 automated ASINs), with no percentage on any tier. Or "The 1% Plan" — "Unlimited automated ASINs for just 1% of monthly ad spend," with no flat base price shown. | scaleinsights.com/pricing |
This is not a hybrid, and it is easy to misread as one. No Scale Insights tier is priced as base-plus-percentage. You pick the per-ASIN ladder or you pick the 1% Plan.
The full ladder, monthly: $78 (5 ASINs), $98 (10), $178 (20), $288 (35), $388 (50), $548 (75), $688 (100). A "Bill yearly -20%" toggle offers annual totals — $748/year at the entry tier through $6,604/year at the top. The 1% Plan routes to "Contact us" rather than self-serve checkout, and its minimum, cap, and definition of "ad spend" are not disclosed.
At 1%, Scale Insights' percentage plan is the lowest published rate in this entire post.
Spend-bracketed flat subscription — scales with spend, but is not a percentage
| Vendor | What's charged | Source, read 19 Jul 2026 |
|---|---|---|
| Zon.Tools | Three plans (Analyzer, Masterer, Dominator) across a 16-step ladder keyed to monthly ad spend, billed per marketplace. At $100–$500 of monthly spend: $9/$19/$25. At $25,001–$50,000: $69/$499/$949. At the top $4M–$5M bracket: $999/$3,499/$5,999. No percentage is charged — there is no "%" character on the page at all. | classic.zon.tools/pricing-2 |
| Ad Badger — software only | Six tiers selected by ad-spend bracket — up to 5k, 25k, 75k, 225k, 750k and 1.5m per month — billed monthly, quarterly, semi-annually or annually. No percentage on any software tier. The prices themselves are not retrievable: the cards are injected by JavaScript and the page's HTML contains the brackets but no figures. | adbadger.com/pricing |
| Teikametrics — Essentials only | $149/month billed annually, $179/month billed monthly, for accounts up to $10K/month in ad spend. No percentage at this tier. | teikametrics.com/pricing |
| Perpetua — Essentials only | $695/mth for accounts up to 10k in monthly ad spend. No percentage at this tier. | perpetua.io/pricing |
Two things to watch in this group.
Zon.Tools bills per marketplace, so a seller on three marketplaces pays three subscriptions. Any head-to-head against a per-account flat price understates it otherwise. I should also flag that the page I could reach is on the host classic.zon.tools, carries a "© 2025" footer, and the apex domain returned an access error to me — so treat these as the classic price list rather than as confirmed current pricing.
Ad Badger's software prices are effectively unpublished. The page offers four billing periods and six spend brackets, and it defaults to the annual view — but the price cards are rendered by JavaScript, so the figures never appear in the page source. I could confirm the bracket structure and the billing periods; I could not retrieve a single dollar amount to quote you. Treat Ad Badger's software as demo-gated in practice, and note that the annual view is the default, so whatever number you see first is a prepaid rate rather than a month-to-month one.
Flat monthly, no percentage anywhere
| Vendor | What's charged | Source, read 19 Jul 2026 |
|---|---|---|
| AdsPlane | Flat monthly at every tier, never a percentage of spend: $0 (Free Local Lite), $35, $79, $235 per month. | adsplane.com/pricing |
| Sellozo | $250/month for the first marketplace, plus $50/month for each additional marketplace, up to 20. Month-to-month, no annual option shown. The vendor's own positioning: "No Percentage Fees," "We charge a flat rate regardless of your ad spend." | sellozo.com/pricing |
| Jarvio | Four flat monthly tiers metered by bundled credits: Free $0 (500 credits/mo), Starter $49, Growth $149, Scale $499. No percentage sign appears anywhere on the pricing page. | jarvio.io/pricing |
One caveat on Sellozo: its dedicated agency pricing page publishes no number and is trial-gated. The $250 + $50 agency figures appear on a separate services page, alongside "Volume discounts available for large agencies," so effective agency rates may be lower than list. Sellozo also lists a separate "Strategic Management" service, which its own navigation describes as "Get matched with a best-in-class agency" — so any fee attached to that engagement is not part of the published software price.
One caveat on Jarvio: it is a general Amazon seller-operations platform covering pricing, inventory, and reviews as well as advertising, so its price is not scoped to ad spend in the first place. Its homepage says plans "scale with usage and SKU count," but no SKU tiers or limits are published on the pricing page.
Not published at all
| Vendor | What I found | Source, read 19 Jul 2026 |
|---|---|---|
| Intentwise | No pricing page exists. /pricing and /plans both return 404, and there is no Pricing link anywhere in the site navigation or footer. Every product page ends in a demo or contact CTA. Whether Intentwise charges a percentage of spend is genuinely unknown — not "no." | intentwise.com (pricing page 404) |
| Entourage | The brand no longer has a live product page. Formerly PPC Entourage, then part of Carbon6, its URL now redirects to SPS Commerce's "Ad Performance" product, where the word "Entourage" does not appear at all. That page publishes no pricing of any kind and routes buyers to "Talk to an Expert." | carbon6.io/ppcentourage → spscommerce.com/products/ad-performance |
Intentwise's public knowledge base does confirm that some add-ons carry extra cost — "Certain offerings, such as Share of Voice and Content Analytics, may incur additional costs" — and directs you to "review your contract or contact your Intentwise Account Manager." That is the closest thing to a published price on the property.
If you find a specific dollar figure for either of these vendors quoted elsewhere, it did not come from their current website.
What this survey actually shows
Nine of the fourteen vendors charge a percentage of ad spend somewhere. Counted from the tables above: Advigator, Scale Insights, Helium 10, m19, Adbrew, Teikametrics, Perpetua, BidX, and Ad Badger. Three are flat everywhere I could see a price: Sellozo, Zon.Tools, and Jarvio. Two publish nothing: Intentwise and Entourage.
Three of those nine won't tell you the rate. Adbrew, Perpetua, and BidX all state on their own pricing pages that a percentage of ad spend applies, and none of them prints a number next to it. You cannot calculate what any of the three would cost you without a sales conversation. That is a legitimate commercial choice, but it means the published price is not a price.
Among the rates that are published, the spread is 1% to 8%. Scale Insights' 1% Plan is the floor; Ad Badger's managed service at 8% is the ceiling. Confine it to software and the published range is 1% to 5% — Scale Insights at 1%, Helium 10 at 2%, m19 and Teikametrics at 3%, Advigator's bands topping out at 5%. Those are the observed numbers from these fourteen vendors, not an industry average, and I would not extrapolate them to the wider market.
The percentage is usually attached to one tier, not the whole product. Six of the nine apply it selectively — Scale Insights to a separate plan, Helium 10 to Diamond, m19 to Professional, Teikametrics and Perpetua to their upper tiers, and Ad Badger to its managed service. Two apply it across the board: Advigator, which has no flat alternative at all, and BidX, which attaches it to every tier including self-serve. Adbrew is the ninth and sits on its own, charging it only when it exceeds the $799 floor. This is why a table that just marks vendors "% of spend: yes/no" misleads more than it informs.
The structural point about percentage pricing
Percentage-of-spend pricing is not automatically bad, and I want to be careful here, because this is reasoning about an incentive structure — not an accusation about how any named vendor actually behaves.
The quirk is this: a vendor paid a percentage of your ad spend is paid less precisely when it does its job right. Good Amazon PPC optimization frequently means cutting spend — pausing targets that don't convert, negating wasteful search terms, pulling bids down on keywords that are buying clicks and not orders. Every one of those correct decisions reduces the fee. The vendor's revenue and your interests point in opposite directions at exactly the moment the work matters most.
That said, the model has a real logic in one place: a managed service, where a human account team's workload genuinely does scale with account size, and where the percentage is a proxy for labour rather than a share of the outcome. Ad Badger's 8% buys a human management engagement including monthly strategy calls. That is a different transaction from software fees.
Where the logic gets thinner is self-serve software. The computation a bid optimizer performs on a $50,000/month account is not meaningfully more expensive to run than the same computation on a $5,000/month account. The percentage there is capturing the value of your growth rather than the cost of serving you.
You may weigh this differently, and plenty of sellers reasonably do — if a percentage-priced tool clearly outperforms a flat-priced one, the fee is worth paying. But it should be a decision you make deliberately, not one you discover eighteen months in.
What this costs at scale, in dollars
Some arithmetic, kept honest. These use published USD rates only. Advigator is excluded because it prices in euros and comparing currencies without an exchange rate would be inventing a number.
Against AdsPlane's $35/month Hosted Starter:
- Scale Insights' 1% Plan — a pure percentage with no flat base — costs the same $35 at $3,500/month in ad spend. At $50,000/month it is $500.
- Teikametrics' "+3% of ad spend over $10K" at $50,000/month of spend is 3% × $40,000 = $1,200/month in percentage alone, on top of an undisclosed custom base. The total is not computable from their page.
- Ad Badger's managed service at 8% of $50,000/month is $4,000/month in ad-spend fee alone, before the $975 base fee — and far above its $2,500/month minimum. It also buys a human team, which the software tiers don't.
The flat side of the same $50,000/month account: AdsPlane's Hosted Pro is $235/month. Sellozo on one marketplace is $250/month. Scale Insights at 50 automated ASINs is $388/month. Zon.Tools in the $25K–$50K bracket is $69, $499 or $949 depending on plan, per marketplace.
Your own numbers will differ — different ASIN counts, marketplaces, and spend levels change the answer a lot. Run them yourself on the flat vs percentage calculator: enter your monthly ad spend and a percentage rate, and watch where the crossover falls for your account rather than for a hypothetical one.
Where AdsPlane stands
AdsPlane is flat monthly at every tier — $0, $35, $79, $235 — and never a percentage of ad spend. That is a locked product decision, not a launch promotion. There is no spend bracket that moves you up a tier, and no managed-service SKU with a percentage attached, because there is no managed service.
The honest limits: AdsPlane is Amazon Ads only, with no DSP or Walmart breadth. It launched in 2026 with a thin review base. It does not yet build a brand-new account's campaign structure from scratch. And on our own ranking of 21 tools we put ourselves third, behind Scale Insights and Helium 10, on maturity grounds. If breadth across retail media is what you need, several of the percentage-priced tools above are genuinely better built for it, and you should weigh the fee against that.
What the flat model buys you is a bill you can predict a year out, and a vendor whose revenue doesn't fall when the right answer is to spend less.
