Scale your AmazonAds Agencywith Fast Ducks.with Fast Ducks.

Holy Quack is Amazon PPC software for agencies managing advertising for multiple clients. It combines daily bid optimization, keyword management, campaign reporting, and an AI assistant called Günther.

Every plan starts with 30 days free, without a credit card. Software from €89 per brand per month, excluding VAT. A brand is one client an agency manages — every Amazon marketplace that brand sells in sits in that one seat. Example: five brands on Analytics is €89 × 5 = €445 per month excluding VAT; seven brands is €623. One brand on eight marketplaces is still €89. Plans: €89 Analytics (dashboards, daily bidding, harvesting, negatives, Amazon Attribution and the AI connector for Claude, ChatGPT and Cursor), and €169 for The whole pond (Analytics plus AMC, and Günther if you bring your own agent). Connect, the AI connector without automations, is €39 per month for up to 5 brands, plus €10 per extra brand. A hosted Günther plan at €269 is coming, including 2,000 AI credits per month. Enterprise done-for-you management is quoted custom per brand. Cancel software anytime.

Yes. Every new customer gets 30 days free, without a credit card. The free month includes every feature, and hosted Günther with a starter credit. It covers one Amazon Ads account with all its marketplaces and brands, once per account. After 30 days you pick a plan to keep access. Your data stays.

There is no sales team and no investor-funded payroll behind the price: Holy Quack is run by one operator and a lot of automation. You pay per brand, not a percentage of ad spend, so your bill does not grow when your clients spend more. There is no long contract either. Your campaigns live in your own Amazon Ads accounts, so if you ever leave, you cancel at the end of the billing period and they stay exactly where they are.

Nothing changes until you decide it should. Daily bidding only runs after you enable it, and only within the floors, ceilings and targets you set. Günther’s structural proposals wait for an authorized user to approve them. Every applied change is logged with what changed, when, and the available reasoning.

Connect your Amazon Ads accounts, choose the advertising profiles, and your reports start syncing. Nothing in your campaigns changes while you look around, so you can compare the dashboards against your current tool first. When you move bidding over, turn off the old tool’s automation for those campaigns so two engines are not adjusting the same bids.

You can build a prototype quickly. The ongoing work is the Amazon Ads API access, keeping every client connection and report sync running, storing the data safely, bid logic with guardrails, a change log, and fixes whenever Amazon changes something. Holy Quack maintains all of that and exposes it as documented tools, so your own Claude, Codex or scripts can use the same account context without you running the plumbing.

Yes, once you enable automated bidding. The bidding engine evaluates performance daily and adjusts bids within the floors, ceilings, targets, and other guardrails you configure. Bids come from a stochastic model or from the rules you set; an AI language model does not calculate the bids.

Günther analyzes your account and prepares structural recommendations with supporting evidence. An authorized user decides whether to apply a proposal. These approval-first recommendations are separate from the daily bidding automation you enable.

Holy Quack helps identify productive search terms, prepare keyword promotions, and manage negative-keyword workflows across connected Amazon advertising profiles.

The dashboards cover campaign, placement, keyword, targeting, and product performance. Data availability depends on the connected advertising profiles, available Amazon reports, and completed syncs.

Create an account and connect the Amazon Ads account you manage. Your free month starts when Amazon is connected, with no credit card. Reports become available as the first data sync completes.

The change history records applied changes so you can review what changed, when it changed, and the available reasoning. Review proposals and configured bidding limits before enabling automation.
