Does Quartile Charge a Percentage of Ad Spend?
Updated August 6, 2026· every figure checked against the vendor’s own pricing page
We cannot confirm it either way, because Quartile publishes nothing about how it charges. As of August 6, 2026 its site has no pricing page at all. The third-party accounts do not settle it either, and not because their numbers differ: one describes a flat monthly tier schedule with no percentage, while another describes a base fee combined with a tiered percentage of spend. Those are two incompatible models, so at least one is wrong, and neither of those two publishers states a source. What is verifiable is the rest of the category: 6 published plans across 5 platforms charge a percentage of ad spend, at published rates from 0.5% to 3%, and vendors calculate that percentage on different bases.
RangeYourself has no affiliate relationship with any platform on this page as of August 6, 2026: every link here goes straight to the vendor’s own site and earns us nothing. We may pursue one in this category, and if we do we will say so here. Either way the ordering follows published prices and each vendor’s own stated terms, and a vendor that pays nothing is listed on exactly the same basis as one that does.

What Quartile publishes about its pricing model
https://www.quartile.com/pricing returns HTTP 200 but serves a response byte-identical to the homepage (119,693 bytes on 2026-08-06), carrying <link rel="canonical" href="https://www.quartile.com"> and the homepage title. Quartile's site navigation contains no pricing link at all (it links /amazon-ppc, /amazon-dsp, /request-demo, /partners and others). The only dollar figures anywhere in that HTML are the marketing stats "$2B+" (Annual Retail Ad Spend Managed) and "$25B+" (Annual Managed Sales). Conclusion: Quartile does not publish a pricing page; quotes are provided after a demo.
Checked 2026-08-06 at https://www.quartile.com/pricing. Quoted from that page: “Request Demo”. The response also carried “<link href="https://www.quartile.com" rel="canonical"/>”, which is what a site emits when a URL is not a distinct page.
There is no fee structure to read, so the question cannot be answered from Quartile’s own material. That is the complete first-party answer, and we would rather give it than fill the gap.
Why the third-party answers cancel each other out
The reports below are the ones that answer this question directly. Read together they describe two different products, which is why we treat none of them as an answer.
| Publisher | Dated | What it reports | States where the figures came from? |

Tier schedule reported: $895 (up to $10,000 ad spend), $1495 ($10,001 to $35,000), $2495 ($35,001 to $70,000), $3995 ($70,001 to $200,000), $6995 ($200,001 to $400,000), $9995 ($400,001 to $1,000,000) Presents discount offers alongside its figures ("you can save up to 50% in the first two to three months with my exclusive discounts"). | No |

This article repeats the $895 to $9,995 range and, in the same piece, reports a different entry-level structure of $2,000 to $3,500 as a base fee. Both figures appear as the article's own reporting. | No |
| SellerStack | No date shown |
A competing Amazon PPC vendor running a Quartile-alternative page. Unlike the others it does not present the range as its own reporting: it attributes it to a published third-party tier schedule, though it does not say which one, and it tells readers to verify before purchase. It sells against the same gap. | No |
One publisher calls it a flat-fee monthly payment on a six-band schedule, which by definition has no percentage component. Another describes a base platform fee with a tiered percentage of spend on top at enterprise level. A buyer cannot act on both. Neither states where its figures came from, and the identical tier schedule shared across publishers suggests a single unattributed origin rather than independent confirmation.
How the rest of the category actually charges
This is the part that is verifiable, and it is more useful than a guess about Quartile. Each rate below is quoted from the vendor’s own pricing page.
| Platform | Plan | Rate | Applied to | Quoted from the vendor |
|---|---|---|---|---|
| Perpetua | Growth | Stated to exist, rate not published | ad spend, on a basis the vendor does not publish | “$695/mth + % of ad spend” checked 2026-08-06 |
| Teikametrics | Advanced | 3% | monthly ad spend above $10,000 | “+3% of ad spend over $10K” checked 2026-08-06 |
| Teikametrics | Enterprise | 3% | monthly ad spend above $10,000 | “+3% of ad spend over $10K” checked 2026-08-06 |
| Helium 10 Ads | Diamond | 2% | monthly ad spend above $20,000 | “For our Diamond and Elite members, Helium 10 Ads is included at no extra cost. A 2% fee is assessed only on any PPC spend exceeding $20K each month. Accounts with under $20K in monthly PPC spend will only pay the Diamond/Elite subscription fee.” checked 2026-08-06 |
| SellerApp | Ecommerce Agency | 0.5% - 2.5% | ad spend, on a basis the vendor does not publish | “Agencies are charged at a starting sum of $300 in addition to a percentage of your Amazon ad spend (ranging between 0.5% - 2.5%).” checked 2026-08-06 |
| Scale Insights | The 1% Plan | 1% | total monthly ad spend, from the first dollar | “Unlimited automated ASINs for just 1% of monthly ad spend.” checked 2026-08-06 |
| m19 | m19 Professional | 3% | total monthly ad spend, from the first dollar | “$479 + 3%” checked 2026-08-06 |
The basis matters as much as the rate. A percentage charged only on the spend above a threshold leaves the first tranche covered by the base fee; a percentage charged on total ad spend applies from the first dollar. Two vendors quoting 3% can bill several hundred dollars a month apart at the same spend for that reason alone.
What you can do instead of guessing
- Ask Quartile directly for the fee structure, in writing, including whether any percentage applies to total spend or only above a threshold, and whether additional marketplaces or DSP carry separate charges.
- Price the platforms that publish first, so you walk into that conversation with a verified benchmark rather than a third-party range.
- Treat any figure you find online for a quote-only vendor as an unconfirmed claim, including the ones quoted on this page.
One thing worth saying plainly, because it shapes what you are reading: RangeYourself currently has no affiliate relationship with any platform on this page, and every vendor link here goes straight to the vendor’s own site. If that changes, this line changes with it. Either way, nothing here is written to push you towards a demo, no vendor pays for placement, and the ranked tables sort on published prices rather than on anything we are paid.
Frequently asked questions
Does Quartile charge a percentage of ad spend?
Unknown, and not because nobody has asked. Quartile publishes no pricing on its own site, so there is nothing first-party to read. Third-party publishers describe two incompatible models, a flat tier schedule and a base fee plus a percentage, and none of them states a source, so we do not adopt either.
Which Amazon PPC platforms do charge a percentage of ad spend?
Verified on August 6, 2026: Teikametrics, Helium 10 Ads, SellerApp, Scale Insights, m19 all publish a percentage component, at published rates between 0.5% and 3%. One further platform states that a percentage applies to one of its tiers without publishing the rate.
Is a percentage of ad spend worse than a flat fee?
It depends on your spend and on the basis the percentage is charged against. At low spend a percentage is usually cheaper than a high flat fee; at high spend it usually is not, because the fee grows with the budget rather than with the work. The crossover is arithmetic, and our cost index shows totals at several spend levels so you can find it for your own numbers.
Do vendors calculate the percentage the same way?
No. Some charge it only on the ad spend above a stated threshold, so the base fee covers the first tranche. At least one charges it on total ad spend from the first dollar. Comparing rates without comparing bases produces the wrong answer.
Are there extra charges beyond the percentage?
Third-party publishers report a per-marketplace surcharge for Quartile, and one of them also reports separate Amazon DSP and onboarding fees. Quartile does not publish any of these, so they remain unconfirmed claims. Among the vendors that do publish, watch for prices stated excluding VAT, prices worded as starting figures, and introductory rates that expire after a few months. Each of those is flagged on the relevant page here.
How we verify this
Every figure on this page was read from the vendor’s own pricing page and is stored with that page’s URL, a verbatim quote, and the date it was checked (most recent: August 6, 2026). Where a vendor publishes no number, we say so instead of repeating a figure from elsewhere. Third-party price reports appear only where they are named, dated, and labeled as that publisher’s claim rather than a verified price. Percentages, thresholds and totals are arithmetic on published figures only. See our editorial standards and how we verify.
