Package Locker & Smart Pickup: Assign, Notify, and Reclaim Lockers

Log an incoming parcel, auto-assign an open locker by size, email the recipient a one-time pickup code, and flag overdue lockers so staff can reclaim them — with a human confirming every assignment and reclaim.

What you'll build

A web tool where mailroom staff log a parcel at the desk, the tool suggests an open locker that fits, staff confirm the assignment, the recipient gets an emailed one-time pickup code, pickup with the code frees the locker, and overdue lockers are flagged for staff-confirmed reclaim — plus a clean usage-log CSV export.

Before you start

  • A Supabase account (free)
  • A Vercel account (free)
  • A Resend account (free)
  • A CSV of your lockers/bins (size + status) and your employee directory
  • Claude Code or any AI coding agent

The problem this kills

Packages pile up at the front desk. Someone tries to remember which cubby has the laptop for Priya in finance, which oversized box is blocking the doorway, and who still hasn't picked up the parcel that's been sitting there for nine days. A delivery comes in and every locker is full — except two are technically empty, but nobody marked them free. Recipients email "did my package arrive?" and staff drop what they're doing to go look. When a locker finally gets reclaimed, there's no record of whose stuff was in it or where it went.

Mailroom and parcel management is a quiet, constant drain on facilities and office-admin teams. The information you need is simple — which lockers are open, what size, who a parcel belongs to, and how long it's been sitting — but without a system it lives in someone's head and a paper logbook. You don't need a developer or an expensive smart-locker vendor to fix that. You can build exactly the tool your building needs.

What you'll build

A simple internal web tool for your mailroom. When a parcel arrives, staff log it at the desk and pick the recipient from your employee directory. The tool looks at your locker list, finds an open locker that fits the parcel's size, and suggests it. Staff confirm the assignment — and only then does the tool email the recipient a one-time pickup code that expires. The recipient comes by, gives the code, staff verify it, and the locker is freed automatically. Lockers that sit too long show up on an overdue report; staff confirm a forced reclaim before anything is removed, so nobody's package vanishes silently. At any point you can export a clean locker-usage log as a CSV in the exact columns your facilities system expects.

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 building — how parcels arrive and get logged today, the exact sizes and naming of your lockers and bins, how your employee directory is structured, your typical and peak daily volumes, your pickup-window and overdue rules, and your messy edge cases (oversized items, perishables, visitor packages, returns). It reads a short spec back to you for a thumbs-up, then builds the tool around your lockers and your rules instead of a generic template. From there it walks the agent through the data model, the directory and locker imports, the assignment-by-size logic, the one-time-code emails, the pickup verification, the overdue/reclaim flow, 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 facilities operation needs: login so only your mailroom team can use it, row-level security so each site or organization only sees its own lockers and packages, a complete audit trail of every assignment, pickup, and reclaim (who, what, when), a hard human-confirmation gate at drop-off and before any forced reclaim, and duplicate guards so the same parcel can't be logged into two lockers at once. The whole tool exists to make a careful human decision easy and fast — the AI suggests the locker, a person confirms it.

Who it's for

Mailroom staff, facilities and office admins, and building managers who own the flood of daily deliveries and are tired of the desk-full-of-boxes chaos. If you can describe how a package gets from the front door to the right person in your building, you can build this.

You've got this — open the plan, paste the first prompt, and you'll be assigning your first real parcel to a locker this weekend.
