TradePeg has several great tools for tracking margins, managing changing prices, and ensuring profitability.
When setting up TradePeg you can choose to use profit margin or markup for margin calculations. This choice will be used throughout the system. See 'Margin & Profit Settings' for configuration.
Most commonly we use Last Buying Price (LBP) to calculate your profit per line (but this can be changed in Settings to consider WAC or Landed Cost instead).
Last Buying Price for an Item is specific to each Warehouse and is updated automatically when good are received (RCT). It is also possible to disable RCT’s updating your LBP, if you want to manage it via importing this information instead.
