# Pricio > Dynamic pricing for Shopify merchants. Pricio syncs a store's catalogue from > Shopify, finds each product's closest listing on Amazon, tracks that competitor's > price on a schedule, and turns the gap into a suggested price the merchant applies > manually or lets Pricio write back to Shopify automatically. Pricio is a Shopify app. Merchants sign in with their Shopify store via OAuth — there is no separate password. Pricing is a single plan: $19/month after a 7-day free trial, billed through Shopify's own billing so charges appear on the merchant's Shopify invoice. ## How it works 1. **Connect Shopify** — one click on Shopify's consent screen. Pricio imports the catalogue, costs and store currency. 2. **Match on Amazon** — Pricio searches Amazon for each product and an AI matcher picks the same or closest equivalent listing, with a confidence score and a one-line reason. Merchants can paste a listing URL instead. 3. **Set a rule** — beat, match or stay above the competitor, or price at cost-plus. Minimum margin, price floor and price ceiling bound every suggestion. The effect on any product can be previewed before saving. 4. **Let it run** — competitors are re-checked hourly, daily or weekly. Suggestions are applied with one click, or a rule can write prices to Shopify automatically. 5. **Stay informed** — alerts when a competitor moves or the merchant's position changes, a tracking log per product, and an undo for every price change. ## What it does and does not do - Competitor data comes from live Amazon listings: price, stock, and "bought in past month" demand. Amazon is currently the only supported marketplace. - Prices are converted to the store's currency at the moment of the check, using the day's ECB rate; the original price and rate are always kept alongside. - The only thing Pricio writes to Shopify is a product's price, and only with the `write_products` scope granted. Every write is logged and reversible. - Pricio cannot read customers, orders or payments, and stores no end-customer data. ## Pages - [Home](https://pricio.ai/): what Pricio does, how it works, and pricing. - [Start a free trial](https://pricio.ai/register): connect a Shopify store. - [Privacy policy](https://pricio.ai/privacy): exact fields read, stored and written. ## Notes for agents - The marketing pages are client-rendered React. The HTML shell carries accurate per-route title, description and canonical metadata; this file is the best plain text source for what the product does. - Everything under `/dashboard`, `/products`, `/dynamic-pricing`, `/reports`, `/subscription`, `/settings` and `/data-management` requires an authenticated Shopify session and is marked `noindex`. There is no public demo data there. - `/api/*` is a private JSON API for signed-in merchants. It is not a public API and requires a session cookie or a merchant-issued key.
