Failed Delivery & Reattempt Tracker
Log failed and refused deliveries with reason codes, then run a reattempt-or-return-to-sender decision behind a coordinator approval gate - so costly redeliveries stop being ad hoc.
An internal tool where coordinators log a failed delivery with a reason code, see a reattempt queue, and approve a reattempt or return-to-sender decision - with a full attempt history, a max-attempts policy, and automatic customer notices.
Before you start
- A free Supabase account
- A free Vercel account
- A free Resend account (for customer and team notices)
- A list (or CSV export) of your shipments and your delivery failure reason codes
The problem this kills
A delivery comes back. Nobody was home, the address was wrong, the customer refused it, the access gate was locked. Now what? Right now that decision lives in someone's head, on a sticky note, or in a thread of "should we try again or send it back?" emails. Some packages get reattempted three or four times when they should have gone back after the first miss. Others sit untouched while the customer waits. Every redelivery costs money, and there's no record of why any of it happened.
You don't have a reason-code problem. You have a no consistent decision problem - and no paper trail when someone asks "why did we try this address five times?"
What you'll build
A simple internal web tool that turns every failed delivery into a tracked, decided, and recorded event:
- A coordinator logs a failed delivery against a shipment, picks a reason code from your taxonomy, and records the attempt number.
- The shipment lands in a reattempt queue.
- The coordinator reviews each one and approves either a reattempt or a return-to-sender (RTS) decision - the human gate.
- The tool enforces your max-attempts policy (e.g., after 3 misses it stops offering "reattempt").
- An automatic customer notice goes out when a decision is made.
- Every event is stamped into an attempt history you can show anyone.
What's inside the Implementation Plan
The plan is a single file you paste into an AI coding agent. It builds the whole tool for you, step by step, in plain language.
It starts by interviewing you about your business. Before writing a line of code, the plan has the agent ask about your current process, your carriers and systems, your real reason codes, your typical and peak failed-delivery volumes, and your exact reattempt rules - then it reflects a short tailored spec back to you for a thumbs-up. The tool you get fits your operation, not a generic template.
From there it walks through the database, the login, the failed-delivery log form, the reattempt queue, the approval gate, the customer notices, and the attempt-history view - each step ending in a ready-to-paste prompt.
The governance it includes (this is the point)
- Login so only your team can use it.
- Row-level security so people only ever see their own organization's shipments.
- A complete audit trail: who logged the failure, who approved the decision, and when.
- A hard human-in-the-loop approval gate - the tool drafts the reattempt-or-RTS recommendation, but nothing is committed or sent until a coordinator approves.
- Duplicate guards keyed on shipment ID + attempt number, so the same failed delivery can't be logged or actioned twice.
Who it's for
Delivery coordinators and customer-service teams who handle failed and refused deliveries and want every reattempt-or-return decision to be consistent, policy-bound, and on the record.
You've got this. Open the plan, paste the first prompt, and let the agent interview you.
