Interactive demo with synthetic data. This environment demonstrates Terra PPC workflows using synthetic advertising, seller-business, financial and economics data. Actions remain inside this demo and are not sent to Amazon or any external advertising or selling account.
Price History
Price periods and promotions per product. Margin and break-even follow the price each unit sold at; a new price applies from its start date and past prices never change.
All information shown in this module is synthetic demo data and does not represent a live Amazon selling account.

Net price = list price × (1 − coupon). “To” is derived from the next period’s start date. Prices are in USD, never converted.
How price periods work
- A price change moves margin and break-even from its start date. From that day the COGS share of price, the contribution margin and the modeled break-even ACoS of every campaign that advertises the product follow the new net price. Simulated order values scale with it from the same day.
- Past prices never change. A new period starts today or later; days already sold keep the price the sales happened at. A mistake is fixed with another period, and every addition is in the Change Log, where it can be undone while nothing changed afterwards.
- One price in force per day. The period that started most recently on or before a day sets that day’s price; without a period the catalog price applies.
- Prices are seller-configured business context in this synthetic demo. Nothing here reads or changes a price on Amazon.
