BidXBidX vs Perpetua: Which Amazon PPC Platform Wins in 2026?
Quick Verdict
Choose Perpetua if...
Best for mid-market Amazon brands who want hands-off AI optimization and multi-marketplace coverage including Instacart.
Choose BidX if...
Best for hands-on operators, agencies, and European brands who want AI-assisted automation with full tactical control and BI-grade reporting.
If you're managing Amazon advertising at scale, you've almost certainly seen BidX and Perpetua on every shortlist. Both promise to take the manual grunt work out of PPC — bid adjustments, keyword harvesting, negative term hygiene — and replace it with AI that compounds performance over time. But despite the surface similarity, these platforms make fundamentally different bets about how Amazon ads should be run.
Perpetua, founded in 2014 and now powering more than 3,000 brands, leans hard into goal-based automation. You tell it what you want — a target ACoS, a sales ceiling, market-share growth — and the engine handles every tactical decision underneath. BidX, founded in 2018 by former Amazon sellers and computer scientists, takes the opposite philosophy: AI assists, but rule-based automation lets operators keep their hands on the wheel. That single design choice ripples through the rest of the product, from reporting depth to pricing structure to who actually thrives on each platform.
We spent the past few weeks digging into both tools — pricing pages, customer reviews, feature documentation, and direct head-to-head comparisons — to build this guide. Rather than rehashing marketing copy, we focused on the questions that actually matter when you're picking a platform you'll live in every day: how much control do you want, what's your ad spend, are you Amazon-only or expanding to Walmart and Instacart, and how much are you willing to pay for hands-off automation versus tactical flexibility? If you're also evaluating the broader landscape, our guide to advertising and PPC tools covers the full category. Below, you'll find a feature-by-feature breakdown, full pricing comparison, and detailed reviews of each platform — followed by a clear recommendation on which to pick based on your specific situation.

Detailed Review
Perpetua
Goal-based AI advertising optimization for Amazon, Walmart, and Instacart
Perpetua (formerly Sellics) is the platform of choice for brands that want AI to do the heavy lifting. Its core differentiator versus BidX is the goal-based optimization model: instead of writing rules or tweaking bids, you set a strategic objective — target ACoS, maximum sales volume, or market share growth — and the engine handles every tactical decision automatically. For mid-market brands spending $10K–$100K/month on Amazon ads, this saves dozens of hours per week of campaign micromanagement.
Where Perpetua really pulls ahead in this comparison is marketplace breadth. While BidX covers Amazon and Walmart, Perpetua adds Instacart to the mix, with unified reporting across all three. For ecommerce brands expanding into grocery and CPG retail media, that single platform reach is hard to replicate. Perpetua also offers stronger out-of-the-box support for Sponsored Brand Video and Sponsored Display campaigns, which matter as brands move beyond simple Sponsored Products into full-funnel advertising.
The trade-off versus BidX is control. If you're an operator who likes to tune bids by hand or build custom optimization rules, Perpetua's hands-off philosophy will feel limiting. The 30-day no-credit-card trial is the easiest way to find out if the goal-based model fits how your team works. Read our full Perpetua review for a deeper feature-by-feature breakdown.
Pros
- Goal-based AI eliminates daily bid micromanagement — set ACoS targets and walk away
- Only platform of the two that covers Amazon, Walmart, AND Instacart natively
- 30-day free trial with no credit card required is the most generous in this comparison
- Stronger Sponsored Brand Video and Sponsored Display automation than BidX
- Lower entry price ($250/mo) makes it accessible for sellers under $10K monthly ad spend
Cons
- Limited granular bidding control — power users who want rule-based tactics will feel boxed in
- Reporting depth lags behind BidX's configurable dashboards and custom metrics
- Pricing scales with ad spend, so high-volume advertisers may pay more than BidX's flat-tier model
BidX is built for the operator who doesn't want to fully hand the keys to an AI. Founded in 2018 by former Amazon sellers and computer scientists, the platform pairs machine-learning bid optimization with deep rule-based automation, giving advertisers the ability to define exactly how campaigns should respond to performance signals. For agencies managing multiple client accounts and in-house teams that treat PPC as a competitive lever, that level of control is the whole point.
Where BidX clearly beats Perpetua in this comparison is reporting and dashboarding. The platform's configurable dashboards — diverse chart types, custom metrics, KPI tracking — genuinely rival standalone BI tools like Power BI. If your team currently exports Amazon ad data into spreadsheets or BI dashboards, BidX can absorb that workflow entirely. The Stock Level Scheduling feature, which automatically throttles ad spend based on inventory, is also a small detail that experienced sellers appreciate.
The trade-offs are real, though. BidX is more expensive at the entry tier — €495/month plus a percentage of ad spend, with annual commitments — and is less established in North America than Perpetua. It also lacks Instacart support, so if your brand sells across Amazon, Walmart, and Instacart, BidX leaves a gap. The 14-day free trial is shorter than Perpetua's 30 days, but the self-service plan is the easiest entry point to evaluate the platform's depth.
Pros
- Rule-based automation gives operators full tactical control — not available in Perpetua's goal-based model
- Configurable dashboards rival standalone BI tools, far deeper than Perpetua's reporting
- Stock Level Scheduling automatically protects budget when inventory runs low
- Strong fit for agencies and European brands managing multi-account portfolios
- Full Amazon DSP and AMC integration in a single interface
Cons
- €495/mo entry price plus percentage of ad spend is significantly higher than Perpetua's $250 starter
- Annual commitment required on all plans — no month-to-month flexibility like Perpetua
- No Instacart support, which Perpetua includes for cross-marketplace brands
- 14-day trial is shorter than Perpetua's 30-day no-credit-card trial
Our Conclusion
Choose BidX if you're a hands-on operator or agency that wants AI assistance without giving up tactical control. The configurable dashboards, rule-based automation, and Walmart-native support make it a strong pick for European brands and agencies managing multiple accounts. The €495/mo entry price plus percentage of spend is steep for tiny sellers, but the dashboarding alone can replace a separate BI tool.
Choose Perpetua if you're a mid-market brand spending $10K–$100K/month on Amazon ads and you'd rather set goals than babysit bids. The goal-based AI is the most mature in the category, the 30-day free trial is genuinely risk-free, and the Walmart + Instacart coverage matters if you're expanding beyond Amazon. You give up granular control, but you get back hours per week.
The honest tiebreaker: if your team enjoys digging into bid logic and wants Power-BI-grade reporting, BidX wins. If your team would rather focus on creative, listings, and product strategy while the platform runs ads in the background, Perpetua wins. Neither is objectively better — they serve different operating styles.
Before committing, take both free trials in parallel on a single ad group and see which interface your team actually opens every morning. That signal tells you more than any feature comparison.

Frequently Asked Questions
Is BidX or Perpetua cheaper for small Amazon sellers?
Perpetua's $250/month Starter plan is the cheaper entry point for sellers spending under $10K/month on ads. BidX starts at €495/month plus a percentage of ad spend, which makes it more expensive for small sellers but potentially better value at scale.
Does BidX support Instacart advertising?
No. BidX focuses on Amazon and Walmart Connect. If you need Instacart ad automation alongside Amazon, Perpetua is the only platform of the two that covers it natively.
Which platform has better reporting?
BidX wins on reporting depth — its configurable dashboards, custom metrics, and chart variety rival dedicated BI tools. Perpetua's reporting is solid but more standardized, and reviewers often note it trails analytics-first competitors.
Can I get a free trial of BidX or Perpetua?
Both offer free trials. BidX includes a 14-day free trial on the Self Service plan. Perpetua offers a more generous 30-day free trial with no credit card required.
Which is better for agencies managing multiple accounts?
Both support agency workflows, but BidX's rule-based automation and dashboard customization tend to suit agencies that need per-client tactical flexibility. Perpetua's goal-based model works better for agencies that want consistent, hands-off optimization across many accounts.
Do either platform integrate with Amazon Marketing Cloud (AMC)?
Yes — both BidX and Perpetua offer AMC integration for advanced audience building and path-to-purchase analytics. BidX's AMC tooling is part of its DSP suite; Perpetua includes AMC starting on its Growth plan.
