About this listing
An application to monitor online shop profitability
This platform assists internet vendors in determining expected profit margins, saving sales scenarios, logging actual sales, and checking performance broken down by product, store, and sales channel.
How it operates
Sellers can model pricing and cost options before releasing a product or adjusting prices, taking into account product cost, shipping, commissions, payment fees, advertising spend, and refunds. Once sales take place, actual figures can be typed in and contrasted with the initial forecasts, giving a clearer view of real results.
All data is added manually; the system does not link automatically to storefronts or advertising networks.

Deployment model
What is delivered is a software base that the buyer installs and operates in their own environment. The manual covers both local use and public deployment on Netlify with PostgreSQL.
At present the project does not feature subscription billing, built-in payments, or automatic syncing with storefront platforms, marketplaces, ad accounts, or payment processors; these would require additional integration work. Hosting, the database, the domain, and any third-party services must be arranged separately by the buyer.
Buyer provides
To proceed, the buyer supplies the domain the order relates to and a brief describing their needs.
