Why keep records?

Most players who flip items on the market count profit in their head. The 3% tax gets forgotten. Buy at 100m, sell at 103m — that's not profit, that's a loss.

This ledger takes the tax off automatically. You see the real net profit of every entry. It becomes clear which item makes money.

Leave the sale price empty and the entry shows as "in stock". When the item sells, enter the price with the Sell button in the table.

Tips
  • Enter prices per piece. We multiply by the qty.
  • Break-even sale price = purchase ÷ 0.97. Below that is a loss.
  • Before listing, see the net amount with the market tax calculator.
  • Track the money sitting in stock from the summary. Money in stock earns nothing.

First the gross sale (qty × sale), minus the 3% market tax, minus total cost (qty × purchase). Example: 1 piece, bought 100m, sold 110m → 110m − 3.3m tax − 100m = 6.7m profit. Profit rate is that profit divided by cost: 6.7m ÷ 100m = 6.7%.

Yes. On the Moradon market 3% of the sale is taken from the seller. It doesn't change by item type. Selling by trade has no tax: tick the Trade box when adding the entry and the ledger takes no tax from it. The box on the Sell button does the same.

Yes. Leave the sale field empty and the entry shows as "in stock". When the item sells, press the Sell button in the table and enter the price. Tax and net profit are computed right then.
