Amazon's Seller app sends no notification for FBA orders. Agent ChaChing plays a cash register sound on your phone for every order, FBA and FBM, on every Amazon marketplace you sell on. One sound, ours: a real till with a coin drop. The alert shows the marketplace, the product and the amount, plus how many orders you have had today. For a pending order the amount is an estimate (โ) from your own current listing price, including a running deal price; the final amount follows quietly in the app. A canceled order never rings a second time. WHY A SOUND Because refreshing Seller Central all day is not a strategy. Put your phone away, get on with your day, and hear it when something sells. WE COUNT WHAT WE MISS Three layers watch your account: a check of your orders every minute, Amazon's own order notification, and a comparison every night. If an alert is late, it says so. Home shows how many orders were missed since you connected, and Orders shows per order how long after the purchase we detected it. NOTHING TO CONFIGURE No developer account, no API keys, no settings in Seller Central. Sign in once on Amazon's consent screen, tap Confirm, done. Sell in more than one region? Connect each one; one subscription covers all of them. WHAT YOU GET - A cash register sound for every order, FBA and FBM - Choose which sales you hear: every sale, or every 5th, 10th, 100th or 1,000th sale of the day - The amount in the alert, or just the fact that something sold - Quiet hours: alerts in that window arrive without sound - Home: your sales for today, yesterday, the last 7 or 30 days, this month or this year, per marketplace and compared with the period before - Top products: the same product across marketplaces on one line, sorted by units or revenue - Orders: every alert, day by day, with every item of the order - Reviews: Amazon's own review request for every eligible order, if you turn it on, with the status always in view - Amounts in the currency you choose - Feedback straight from the app; we reply by email - All your devices - The app in English, German, French and Spanish YOUR DATA STAYS YOURS Reads your orders. Review requests only if you turn them on. Agent ChaChing uses two Amazon roles: Inventory and Order Tracking reads your orders, and Buyer Solicitation is only used when you switch on review requests (they are off by default). Then we send Amazon's own Request a Review message, at most one per order and only when Amazon offers it for that order. The text of that message is Amazon's and can't be changed. We never change your listings, prices or stock, and we read nothing about your buyers: no names, no addresses, no email addresses, no postal codes. Delete your account and all data in Settings. PRICING 14 days free, then USD 5.99 per month or USD 49.99 per year, which is three months free. One plan, everything included, no daily limit on alerts. Cancel any time. SUBSCRIPTION TERMS Agent ChaChing Pro is an auto-renewable subscription: 1 month for USD 5.99 or 1 year for USD 49.99, after a 14-day free trial. Payment is charged to your Apple Account when the free trial ends, or at confirmation of purchase if you have no trial. The subscription renews automatically unless it is canceled at least 24 hours before the end of the current period. Manage or cancel it in your App Store account settings.
