EU landed-cost calculator

You are a senior product engineer. Turn the product idea below into a locally runnable MVP.

## Idea

EU landed-cost calculator
Helps Etsy and Shopify sellers recalculate the landed price of EU orders.

## Product concept

Build a landed-cost and responsibility guidance tool for small cross-border sellers: they enter the product category, shipping origin, destination country, sale price, and shipping cost, then get a buyer-facing landed-price explanation, store announcement copy, and order-processing notes. The focus is not to replace customs systems. It is to help sellers quickly update product pages and customer-service messaging.

## Why now (backed by facts)

Online sources indicate that the EU will remove the €150 duty-free threshold on July 1, requiring platform sellers to recalculate landed prices and customs responsibilities. This will directly affect product-page pricing and after-sales explanations.

## Direction (model inference, not independently verified)

Target user: Small businesses shipping to the EU through Etsy, Shopify, or their own websites that usually calculate shipping and taxes in manual spreadsheets.

Minimal entry point: Start with a web calculator: select the destination country and product category to get a landed-price breakdown, product-page prompts, and customer-service replies. Leave out platform-based automatic repricing, fully automated customs declarations, and complex enterprise workflows.

The strongest case against: The strongest case against this is that logistics providers and platform checkout products may absorb the tariff rules. If an independent tool cannot connect to order flows, sellers may use it only briefly during the policy change.

These are the model's inferences from the idea itself and the verified facts. Treat them as directional hypotheses against real constraints: do not assume the strongest counter-argument is already solved, and do not write them into the product as certainty.

## Punching above weight (model inference)

Target keywords such as “EU small-parcel duty removal” and “how Etsy collects EU duties”; promote reusable store-announcement templates in Etsy seller communities and cross-border e-commerce groups.

## Competitors & gaps (model inference)

- Zonos: Focused on mature cross-border checkout and tax solutions, while small sellers may only want to know how to update their product pages.
- Avalara: Covers tax compliance broadly, but education and response generation for lightweight sellers are not core entry points.
- Easyship: Focused on logistics and shipping-cost management, with limited support for product-page copy and customer-service explanations during policy changes.

## How it makes money (model inference)

Use a free calculator for acquisition, then monetize bulk product checks, saved templates, and platform syncing through subscriptions.

## Deliverables

- Before you start, distill 3–5 verifiable acceptance criteria from the concept and minimal entry point above, list them, and walk through them one by one on delivery.
- Ship the core flow described by the minimal entry point first, so the core user can get through it; leave out generic systems (accounts, payments, admin) unless they are truly necessary.
- Do not show unverified market numbers in the UI or API.
- Keep key copy calm and verifiable; when the product needs domain facts or safety guidance, adapt them from the Sources list or equivalent authoritative pages and cite them — do not write them from general knowledge.
- If building inside an existing project: read the README, dependencies and conventions first; follow the existing stack and style, and do not refactor unrelated code.
- If the current directory is empty: pick a lightweight stack and prioritize a runnable prototype.
- When done, explain what changed, how to run it, and how to verify it.
- Ask only when an ambiguity would genuinely change the product direction; make ordinary implementation calls yourself.
