If you're researching Perpetua as an Amazon advertising tool in 2026, you've probably already found the reviews. The April 2026 Trustpilot page for Perpetua includes accounts of sellers losing six figures after being locked into annual contracts they couldn't exit, billing disputes that went to collections, and customer support that disappeared when it mattered most.
This isn't a pile-on. We built Calbridge because we were managing $500,000 per month in Amazon ad spend ourselves and couldn't find a tool we trusted. This comparison is meant to give you an honest picture of both options so you can make the right call for your business.
Note on Perpetua reviews (April 2026): Multiple sellers report being unable to exit annual contracts, with disputes escalating to collections agencies. One review describes a "six-figure loss" attributable to ad mismanagement during their Perpetua contract. We can't verify individual claims, but the pattern is consistent enough to warrant serious due diligence before signing an annual contract with any tool.
Perpetua is a well-funded, enterprise-grade tool. If you're a massive brand with a dedicated account manager and you need advanced DSP capabilities at scale, it may be worth the cost. But for the vast majority of Amazon sellers — brands doing $500k to $10M/year, agencies managing 5 to 50 clients — Perpetua is expensive, inflexible, and the contract structure creates real downside risk.
Calbridge was built specifically for that middle tier: serious enough to need real analytics, small enough that enterprise pricing and annual contracts are a genuine threat to the business.

This is worth addressing directly. Perpetua's pricing structure has historically involved annual commitments, and recent reviews suggest that exiting those contracts mid-term is difficult or impossible. For brands spending $5,000–$50,000/month on ads, committing to a year-long software contract — on top of the ad spend itself — creates compounding risk.
The scenario that appears in reviews: ad performance degrades, you want to switch tools or cancel, but you're contractually locked in and the dispute process is opaque. That's not a theoretical risk. It's what happens to real businesses.
Calbridge is month-to-month. Always. If it's not working for you after 30 days, you cancel and pay nothing further. We'd rather compete on performance than on lock-in.
The single biggest analytical gap in Perpetua — and most Amazon ad tools — is that they show you ACoS and ROAS, but not profitability. Those are different things.
A campaign with a 15% ACoS looks great. But if your product costs $22 to make, Amazon takes $9 in fees, and your FBA storage is another $2, your contribution margin might be negative before you account for a single dollar of ad spend.
Calbridge shows you CM1 (revenue minus COGS and fees), CM2 (CM1 minus ad spend), and CM3 (CM2 minus overhead) — per ASIN and per campaign. That's the number that tells you whether your business is actually working, not just whether your ads are generating clicks.
If you manage multiple Amazon brands — whether as an agency or as a brand operator with multiple accounts — Perpetua requires a separate subscription per account and doesn't offer a white-labeled client portal. Your clients can't log in and see their own data without seeing your entire Perpetua account.
Calbridge was built for this from the ground up. The Agency plan includes a white-label portal with your logo, per-client login access, a multi-brand switcher, and a Report Builder that exports branded PDF reports for each client. One subscription, your brand, your clients' data isolated appropriately.
