Short version: Mercanto automates your Amazon PPC campaigns using AI. You pay monthly, cancel anytime, and we back results with a 30-day performance guarantee. We handle your advertising data responsibly and never touch your Amazon credentials directly.
Mercanto is an AI-powered Amazon PPC optimization service. It connects to your Amazon Advertising account to analyze campaign performance data and provide automated bid adjustments, budget reallocation recommendations, keyword harvesting, and negative keyword management.
By using Mercanto, you agree to these Terms of Service and our Privacy Policy. If you don't agree, don't use the service.
You must be at least 18 years old and have the legal authority to enter into this agreement on behalf of yourself or your business.
You are responsible for maintaining the security of your Mercanto account. Choose a strong password and don't share your login credentials.
You are responsible for all activity that occurs under your account. If you suspect unauthorized access, notify us immediately at mercanto@polsia.app.
One account per person or business entity. You may not create multiple accounts to circumvent plan limits or the performance guarantee.
Mercanto offers one subscription plan, billed monthly. Current pricing:
All prices are in euros (EUR) and include applicable VAT where required. Subscriptions renew automatically on the same date each month unless cancelled.
Payments are processed by Stripe. By subscribing, you authorize us to charge your payment method on a recurring monthly basis until you cancel.
We reserve the right to change pricing with at least 30 days' notice. Price changes apply to new billing periods after the notice period.
If Mercanto doesn't improve your PPC performance within the first 30 days, you get a full refund.
Specifically: if you connect your Amazon Advertising account, run Mercanto's optimization for at least 30 consecutive days, and your ACoS has not improved (decreased) or your ROAS has not improved (increased) compared to the 30 days before you started — we will refund your first month's subscription in full.
To claim the guarantee:
The guarantee applies to your first subscription month only and to accounts that connected a live Amazon Advertising account with active spend (at least €500 total ad spend during the 30-day period).
You can cancel your Mercanto subscription at any time from your account settings. Cancellation takes effect at the end of your current billing period — you retain access until then.
We do not provide pro-rated refunds for partial months unless covered by the 30-day performance guarantee (Section 4) or required by applicable EU consumer protection law.
EU consumer rights: If you are a consumer (not a business) located in the European Union, you have a 14-day right of withdrawal from the date of your first subscription. To exercise this right, contact us at mercanto@polsia.app before the 14-day window expires. This right does not apply if you have actively used the service during that period, as described under EU Directive 2011/83/EU.
