MJ Trade Notes

A small trading desk lives between two numbers: what a consignment costs and what it sells for. MJ Trade Notes keeps that arithmetic and the paperwork notes in one pocket book. The margin screen takes a buy price, a sell price and a quantity, and lays out the gross margin, the markup percent and the profit for the lot, all from the figures you type. The unit converter reprices a lot between units: enter a per-case price and the units in a case, and read the per-unit figure next to it, in either direction. The consignment ledger is the record book. Each note carries a reference, the goods description, the quantity and a short comment; notes can be edited or removed, and the list keeps a count of open notes at the top. Records are saved on the device in standard Android storage, so the desk book opens instantly wherever the day goes.
