Can I switch from Quartile easily?

Yes. Both tools connect to Amazon via OAuth. You can run Prism alongside Quartile during a transition period, or switch directly. Your historical campaign data stays in Amazon, Prism will analyze it immediately. Most sellers see their first insights within hours.

What about multi-account/agency features?

Prism includes multiple accounts in each tier with no per-account fees: Growth tier includes up to 3 accounts, Pro includes up to 15. Quartile charges $895 base + $500 per additional account. Managing 3 accounts: Quartile costs $1,895/month, Prism Growth costs $199/month (89% savings). For agencies managing 15 accounts, you save over $89,000/year with Prism.

Is Prism's AI as good as Quartile's?

Prism uses adaptive machine learning that learns from your specific account patterns, similar underlying technology to Quartile. The difference is we add LLM-generated explanations on top, so you understand every decision. Many users report similar or better ACOS results with Prism, plus the benefit of transparency.

Why is Prism so much cheaper?

We chose flat-rate pricing because we believe percentage-based fees misalign incentives, you shouldn't pay more just because you're scaling successfully. Our costs don't increase proportionally with your ad spend, so neither should yours. We're building a sustainable business on value, not rent-seeking.

Published: December 21, 2025

Quartile is a powerful enterprise PPC platform. But for many sellers, it comes with two frustrations: black-box AI that doesn't explain its decisions, and tiered pricing ($895-$9,995/mo based on ad spend) that grows as you scale.

If you're paying thousands per month to Quartile and wondering "why did the AI do that?", there's an alternative built on transparency.

Why Sellers Look for Quartile Alternatives

⚠️
Expensive per-account pricing
$895 base + $500/month per additional seller account. Managing 5 accounts costs $2,895/month just for the tool. Plus $500/mo per additional marketplace, costs climb quickly as you scale
⚠️
Black-box AI decisions
The ML makes changes, but you can't see why specific recommendations are made
⚠️
Hidden statistical validation
No way to see confidence levels or understand if changes are statistically significant
⚠️
Enterprise complexity
Built for large brands with teams, overkill for growth-stage sellers
⚠️
No guided workflow
Powerful tools, but no structured approach to weekly optimization
