Frequently asked questions
Short answers about privacy, marketplace fees, and who IDMP is for.Privacy and data
Yes. IDMP runs entirely in your browser: every calculation happens on your device, and nothing you type is sent to us. There is no server-side account or database, and the app includes no analytics or tracking scripts.
In this browser's local storage on this device. Saved scenarios are not synced between browsers or devices, and clearing IDMP's site data in your browser deletes them permanently. To move a scenario elsewhere, copy its summary or note the prices down.
Marketplace fees
No. Each marketplace starts from an illustrative fee profile so you can explore the calculator immediately; it is not a quote of current seller costs. Real fees depend on product category, seller tier, and active programs, and marketplaces change their rates regularly. Replace the preset fee lines with the fees shown in your Seller Center before relying on a result.
Check the official seller pages for each marketplace. They are the authoritative source and reflect the latest changes:
About IDMP
Online sellers on Indonesian marketplaces: Shopee, TikTok Shop, Tokopedia, Blibli, and Lazada. It suits solo sellers and small teams who price in IDR and want tooling in English or Bahasa Indonesia.
You usually know the profit you want, not the price that produces it. IDMP works backwards: set a target profit (amount or percent) and it solves for the lowest listing price that still reaches it after stacked percentage fees, fee caps, extra costs, and rounding increments. It also shows the full fee breakdown and compares all five marketplaces side by side, which is slow and error-prone to redo manually for every product.
