Return-Reason Analytics: Finally See Why Customers Send It Back
Turn a messy returns CSV into clean return-reason categories trended by SKU, customer, and period — with an analyst approving the tagging refresh before the dashboard publishes.
A web tool where you import your returns history, AI clusters messy free-text reasons into clean categories and trends them by SKU, customer, and period, an analyst reviews and approves the categorization before anything publishes, and the result is a shareable dashboard plus a clean CSV export.
Before you start
- A Supabase account (free)
- A Vercel account (free)
- A Resend account (free)
- A historical-returns CSV with reasons (free-text is fine)
- Claude Code or any AI coding agent
The problem this kills
Your returns data is a graveyard of half-truths. One person typed "to big," another wrote "TOO LARGE," a third just picked "Other" and left a sentence in the notes field. The reason codes your system offers don't match how customers actually talk, so the real story — that a specific SKU runs small, that one wholesale account returns half of everything they order, that defects spiked the month you switched suppliers — is buried under inconsistent free-text and useless catch-all codes.
So nobody can answer the question that actually matters: why are things coming back? Merchandising guesses. Quality reacts to whatever complaint is loudest this week. Ops eats the restocking cost and moves on. The data to fix the root cause is sitting right there in your returns export — it's just too messy to read. You don't need a data team or a BI license to fix this. You can build the tool yourself.
What you'll build
A simple internal web tool. You import your historical-returns CSV — RMA number, SKU, customer, return date, and whatever reason text exists, however messy. The tool dedupes on RMA so nothing is double-counted, then AI clusters the free-text reasons into clean, consistent categories ("Too small," "Defective," "Not as described," "Changed mind," and so on) and maps the original junk text to those categories. It trends every category by SKU, by customer, and by time period, so you can finally see which products and accounts drive which kinds of returns.
Then the human gate: an analyst reviews the proposed categorization — renaming categories, merging duplicates, re-tagging anything the AI got wrong — and clicks Approve. Only then does the dashboard publish with the refreshed tags, and the tool produces a clean CSV export in the columns your 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 business — which system your returns come from, exactly what your CSV columns are named, how reason codes and free-text actually look in your data, your SKU and customer naming conventions, your typical and peak return volumes, and the messy edge cases (refused deliveries, warranty swaps, partial returns) — and then it tailors the data model, the categories, and every later step to your answers. This is 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 walks the agent through the import, the dedupe-on-RMA logic, the free-text clustering into clean categories, the trending by SKU/customer/period, the analyst review-and-approve screen, the dashboard publish, and the CSV export — each step with a ready-to-copy prompt. There's also a fallback so you can build the whole thing today even with no API to your order or returns system.
The governance it includes (this is the point)
This is a real reporting tool, so it ships with the controls a team needs to trust the numbers: login so only your team can use it, row-level security so you only ever see your own organization's returns, a complete audit trail of who re-tagged and approved which categorization refresh and when, a hard human-approval gate so the dashboard never publishes a categorization an analyst hasn't signed off on, and duplicate guards keyed on RMA so the same return can't be counted twice. The AI proposes the tags; a person decides what the business actually sees.
Who it's for
Ops managers, quality leads, and merchandising teams who own returns and are tired of staring at inconsistent reason codes that explain nothing. If you can describe how a return moves through your shop and what your returns export looks like, you can build this.
You've got this — start with the plan, paste the first prompt, answer the interview, and you'll watch your messy return reasons resolve into a dashboard you can actually act on the same afternoon.
