Find out what a board costs before you build it. PartsBox prices a Bill of Materials from live distributor offers and your own local quotes, and recomputes the moment a quantity or a price changes.
Import a BOM as CSV or TSV from KiCad, Altium, EAGLE, or any tool that exports one. Map the columns once and save the mapping as a preset. PartsBox matches each line to a part by ID Anything™ code, CAD key, or name, and highlights anything it cannot match, so nothing is priced by accident. A BOM line can also be a service or labor, such as assembly or testing, so a quote covers the whole job, not only the parts.
For every part with a manufacturer part number, PartsBox gathers the distributor offers — typically twenty to forty — and picks the best one for you. Selection accounts for the things a spreadsheet ignores:
PartsBox ranks offers by effective price, the real cost once any unavoidable excess is counted, so it can tell you when buying more is cheaper. The best offer changes with batch size, which surfaces sources that only make sense at volume. Set the build quantity to price one board or a full run, and choose whether to use local stock, buy everything fresh, or use stock first and buy the rest.
A part bought by length, weight, or volume is priced just as carefully. Each offer shows two prices: the cost of a whole vendor package, such as a spool or a reel, and the cost per part unit, such as $0.14/mm. PartsBox ranks offers in a common unit, so a spool and a reel, or two substitutes in different packaging, compare directly.
Vendor rules decide which distributors count. Order them into fallback chains — prefer two low-cost vendors, fall back to a third — and switch chains instantly to compare sourcing strategies. Export the priced BOM as a PDF with your company logo.
BOM import is in every plan. BOM pricing, multiple currencies, and vendor rules start on the Essentials plan.
