Stockroom Issue & Return Log
Build an internal tool that logs every material issue out of the stockroom and every return back in — who took what, for which job, how much — so your count stays accurate and unexplained shrinkage becomes traceable.
A logged-in tool where attendants record material issues and returns against a job, stock is checked before it posts, a controller approves flagged transactions, and you can export a clean issue/return ledger plus a stock-change CSV.
Before you start
- A list of your stockroom items (a spreadsheet is fine)
- Your charge targets — work orders, jobs, or cost centers
- Free Vercel, Supabase, and Resend accounts
The problem this kills
Material walks out of the stockroom on a clipboard, a sticky note, or "I'll log it later." By month-end your on-hand count doesn't match reality, jobs get charged for parts they never used, and nobody can explain where the missing material went. When something is short on the line, the hunt starts — and there's no record of who issued what, to which job, or whether it ever came back.
Returns are even worse. Opened or partly-used material gets tossed back on the shelf with no quality check, and now your "available" count includes parts that should never have been re-issued.
This tool replaces the clipboard with a fast, logged-in screen that checks stock before it posts, flags the risky moves for a controller, and keeps a permanent record of every issue and return.
What you'll build
A small internal web app your stockroom team logs into. An attendant picks an item, enters a quantity, and charges it to a work order, job, or cost center — and the tool confirms there's enough on hand before it lets the transaction through. Returns work the same way, with returnable material handled separately from consumables, and opened or used material automatically flagged for a quality check.
Anything above your approval threshold — a big issue, or a return of opened material — waits in an approval queue. A controller reviews and approves it, and only then does stock post. Everything is recorded: who, what, how much, which job, and when. When you need it, you export the full issue/return ledger and a stock-change CSV in the exact columns your system of record expects.
What's inside the Implementation Plan
The plan is a runbook you paste into Claude Code (an AI coding agent). It builds the whole tool with you, step by step, in plain language.
It opens by interviewing you about your business — your items and how they're named, your work-order/job/cost-center codes, your typical and peak transaction volumes, your approval thresholds, and your messy edge cases — so the tool is tailored to how you actually work, not a generic template. The agent reflects a short spec back to you and waits for your thumbs-up before it builds anything.
From there it sets up your database, login, the issue and return screens, stock validation, the controller approval queue, the audit trail, and the CSV import/export — each step ending with a ready-to-paste prompt.
The governance it includes (this is the point)
- Login so only your team can use the tool.
- Row-level security so people only ever see their own organization's data.
- A complete audit trail — who issued or returned what, for which job, and when.
- A human-in-the-loop approval gate — flagged issues and opened-material returns wait for a controller to approve before stock posts. The AI drafts; a person commits.
- Duplicate guards — a transaction key (item + job + timestamp) stops the same move from being logged twice.
Who it's for
Stockroom attendants, line supervisors, and inventory controllers who need accurate counts and a traceable record — without waiting on IT or a six-month ERP project.
