Equipment Loan & Tool Crib Checkout: A Lending Library for Your Shared Gear
Let staff browse, request, and borrow shared equipment with a due date — while an attendant approves every checkout and confirms every return, and overdue items chase themselves.
A web tool where staff browse a catalog and request items with a return date, an attendant approves each checkout and confirms each return, overdue items trigger email reminders and escalations, and you export the full loan history as CSV.
Before you start
- A Supabase account (free)
- A Vercel account (free)
- A Resend account (free)
- A CSV of your loanable items with quantity on hand, and a CSV of your staff list
- Claude Code or any AI coding agent
The problem this kills
The camera is "somewhere." The good drill walked off three months ago and nobody knows who has it. The demo laptop is double-booked for two client visits on the same Tuesday. Your shared-equipment list lives in a whiteboard, a clipboard, or a spreadsheet that's always one checkout behind reality — so you genuinely don't know what's available, what's out, who has it, or when it's coming back.
Shared gear is expensive, and the cost of losing track of it isn't just the replacement — it's the meeting that happened without a projector and the shoot that got rescheduled. The fix isn't a fancy asset-management suite with a per-seat license; it's a simple lending library that knows your quantity on hand, won't let you lend the eleventh of ten items, keeps a person in the loop at hand-over and return, and nags the people who are late so you don't have to. You do not need to be a developer to build that.
What you'll build
A simple internal web tool for your facilities, AV, or lab team. Staff log in, browse the catalog of loanable items, and request one with a return date. An attendant approves the checkout — confirming the item is physically in the borrower's hands — and only then does availability drop. As the due date approaches, the tool emails reminders; when an item runs late, it escalates by email. When the borrower brings it back, the attendant confirms the return (and jots a condition note), the item flips back to Available, and the borrower's record is cleared. Everything is logged, and you can export the full loan history as a CSV any time.
What's inside the Implementation Plan
The downloadable plan is a step-by-step file you paste into an AI coding agent. It opens by interviewing you about your business — what kinds of gear you lend, how your catalog and quantities are tracked today, the real fields and codes (asset tags, serial numbers, SKUs) in your data, who's allowed to borrow, your loan-length and approval rules, and the messy edge cases like kits that lend as a set or items that come back broken. It reads a short spec back to you for a thumbs-up, then builds the tool around your answers instead of a generic template. From there it walks the agent through the data model, the catalog import, the request-and-approve flow, the due-date reminders and overdue escalations, the return-and-condition step, and the CSV export. Every step ends with a ready-to-copy prompt.
The governance it includes (this is the point)
This isn't a toy. The plan builds in the controls a real operation needs: login so only your team can use it, row-level security so each site or department only sees its own equipment and loans, a complete audit trail of every request, approval, reminder, and return (who, what, when), a hard human gate so an attendant must approve each checkout and confirm each return before anything changes hands or clears, and duplicate guards so the same person can't open two active loans on the same item by double-clicking. The whole tool exists to keep a careful human in charge of the physical hand-over — the app does the chasing and the bookkeeping.
Who it's for
Facilities and AV teams, lab and shop managers, tool-crib attendants, and office managers — anyone responsible for a shelf, cage, or closet of shared gear that walks off, gets double-booked, or comes back broken. If you can list what you lend and how long people get to keep it, you can build this.
You've got this — open the plan, paste the first prompt, and you'll be checking out your first real item this afternoon.
