Every camera, lens, light and cable in one place, with three day rates that cascade, cases that know what is in them, and an importer that reads a spreadsheet, a PDF, a photo of a list or a pile of receipts. This is the screen the rest of the app leans on hardest.

Categories are the top-level grouping and every item is in exactly one. Locations are where a thing physically sits. Kits are named bundles with one blended day rate.
Each item carries In studio, Outside / on location and ShareGrid / public day rates. Leave one blank and it falls back down the chain, so a gear list at outside rates uses Outside, or In studio if there is none.

Import equipment takes a CSV, a PDF, a photo, or pasted text. Files it recognises are read directly; anything else gets a Read it with AI → offer. Either way you land on the same review: tick what you want, untick misreads, add.
Yes. Sell this → on any item fills a market listing from the shelf — name, model, SKU, purchase date, photo, category — and attaches provenance the app can vouch for. Serial numbers and notes never go into a public listing.
No. Only what you choose to publish is public: an item with a ShareGrid link appears as kit for hire on your page, and a listing you create appears on the market.
The full inventory — kits, cases, packing, receipts — is on Solo and up. Bulk CSV import of an equipment list is Studio and up. See pricing.
A gear list that marks an item in case sets it out in the inventory until it is marked returned, and the calendar's conflict detection sees it on that job.
Drop the spreadsheet you already have. The sandbox shows the review screen on a real list first.
