Scan-to-Confirm Pack Verification

The problem this kills

A picker grabs the wrong finish. A box goes out one unit short. A substitute slips in that nobody signed off on. You don't find out until the customer does — and now you're paying for a return, a reship, and a bruised reputation.

The usual "fix" is a paper checklist taped to the bench that everyone stops reading by 10 a.m. There's no record of who packed what, no way to stop a short order from shipping, and no approval trail when someone swaps an item.

This Implementation Plan walks you through building a pack-verification screen that catches the mistake before the box is taped shut — and keeps a clean record of every confirmation and every exception.

What you'll build

A simple internal web app your packers actually use:

• Open an order and see every line it should contain.
• Confirm each line by scanning a barcode or tapping it off — the screen tells you instantly if a SKU doesn't belong to this order or if you've scanned too many.
• Flag mismatches the moment they happen: wrong item, over-count, missing line.
• Route exceptions — short packs and substitutions — to a warehouse lead, who approves or rejects before the order can move.
• Mark it packed only when every line is accounted for and every exception is signed off.
• Export a clean shipped CSV in the exact columns your shipping or ERP system expects.

It works with a real barcode scanner (which just types the code for you) or with plain finger-tap confirmation if you don't have one.

What's inside the Implementation Plan

• It interviews you first. Before writing a single line of code, the plan has the AI agent ask you about your business — your order numbers, your SKU and barcode format, how partial packs and substitutions actually work on your floor, your peak-hour volumes, and your messiest edge cases. It reads back a short tailored spec, you give a thumbs-up, and then it builds a tool shaped to your operation — not a generic template.
• A clear definition of done so you know exactly what "finished" looks like.
• Step-by-step build instructions, each ending in a ready-to-paste prompt.
• A simple architecture diagram so you understand what you're building.
• A "No API yet?" fallback that loads orders from a Google Sheet or CSV and exports a clean shipped CSV — so the whole thing is buildable today, even with zero integration to your current system.
• A verification checklist to confirm it really works.

The governance it includes (this is the point)

This isn't a toy. Every build in this plan bakes in the controls a real warehouse needs:

• Login so only your team can open the tool.
• Row-level security so each location or org only ever sees its own orders.
• A full audit trail — who confirmed which line, who approved which exception, and exactly when.
• A hard human-in-the-loop gate: a short pack or substitution is drafted by the packer, but the order cannot be marked shipped until a lead reviews and approves it.
• Duplicate guards keyed on the order ID, so the same order can't be verified and shipped twice.

Who it's for

Packers, QC checkers, and warehouse leads who are tired of returns caused by wrong or missing items — and the ops person who wants to fix it without waiting six months for IT.

You've got this. Open the plan, paste the first prompt, and let's build it.
