You need to know one thing: do you have this part, and where is it? PartsBox answers as you type. Search by name, manufacturer part number, your own internal part number, manufacturer, description, footprint, notes, or a custom field, and the whole database responds instantly — the search index lives in the browser, so results appear as you type even with thousands of parts. The search is fuzzy, so a few characters from the middle of a part number are usually enough: typing 61a20dwp finds the TPA6120A2DWP.
Type, scan, or filter. Typing is the everyday path: a fragment of a name or an MPN, and the part is on the screen. Prefix a word with # to filter by tag exactly — 4k7 #0402 #resistor narrows to parts tagged resistor and 0402, then searches for 4k7 within them. For a structured question, filter any table by any column: footprint, manufacturer, stock level, a custom field, or several conditions combined.
Work from the shelf when that is faster. Every part, bin, and reel carries an ID Anything™ code. Scan it with a camera or a USB scanner and you land on that exact part or location in PartsBox, with its stock shown. Scan the distributor barcode on a bag you just found, and PartsBox identifies the part and shows what you already have, so you do not order a second reel of something already in a drawer.
Open a part and its stock is in front of you: how many you have and in which storage locations. A storage location can be a room, a shelf, a box, or one compartment in a grid, so the answer is the exact bin, not "somewhere in that drawer." A part with zero stock still earns its place: it shows what needs ordering and matches BOM lines.
The part also carries everything you reach for next: the datasheet, photos, and specifications of a linked part, your notes and attachments, and the full stock history — every add, remove, and move, kept permanently. When the exact part is out, its approved substitutes are one click away, and a meta-part shows the combined stock of all its interchangeable members, so "do I have something I can use instead" gets an answer too.
Set a low-stock threshold on a part, and PartsBox flags it and lists it in a low-stock report the moment stock drops below it.
PartsBox tracks what you paid and what remains: for each part, the total purchase cost, the average price per unit, and the current value on hand — and the value of the whole inventory in your own currency, for insurance or accounting. With lot control, valuation is exact per lot instead of an average.
This is the everyday question an inventory has to answer, and it works the same whether you keep a hundred parts or a hundred thousand. Search, stock, and storage are the core of PartsBox, not an add-on.
Search, stock, storage, and low-stock warnings are in every plan, including the free Maker plan. Stock valuation starts on the Essentials plan.
