Compliance Radar for Cross-Border E-commerce

GPSR, EPR, state sales tax, packaging laws — one calendar that tells sellers what applies and when.

Overview

Selling physical products across borders now means navigating an accelerating pile of regulations: EU GPSR (Dec 2024), country-level EPR packaging registration, US state sales-tax nexus, UK/EU 'responsible person' requirements, battery and textile rules landing 2026–27. Sellers discover obligations only when a marketplace suspends their listings.

The product: answer 10 questions about what you sell and where, get a personalized compliance calendar with plain-English task explanations, deadline alerts, and links to registration portals or vetted service partners. It's not legal advice — it's the missing map. Referral fees from compliance service providers (EPR registrars, tax filers, authorized-rep services) create a second revenue engine.

The problem

Cross-border sellers face dozens of jurisdiction-specific obligations with no unified overview. The current 'solution' is panicked Reddit threads after Amazon suspends a listing.

Who has this problem

Amazon FBA / Shopify / Etsy sellers doing $100k–$20M across borders — hundreds of thousands of businesses; also bookkeepers and e-commerce consultants serving them.

Why now

Regulatory density spiked: GPSR enforcement began late 2024, EPR schemes multiply annually, and marketplaces now enforce proactively (suspension first, questions later). Each new rule is a fresh acquisition wave of panicked sellers.

Competition landscape

Point solutions per domain exist (Avalara/TaxJar for US tax, country EPR registrars, GPSR rep services) but nothing unifies the overview. Seller forums and Facebook groups are the actual competitor — beat them with personalization and alerts.

Signalist verdict

Non-discretionary spend, recurring by nature, and every new regulation is free marketing. The hard part is content ops — keeping rules current across jurisdictions is the product and the moat. Start with 2–3 corridors (US→EU, UK→EU, CN→US) instead of boiling the regulatory ocean.
