TL;DR

420.com needed a fully functional, compliant Shopify store live in under three weeks, selling hemp products across every U.S. state except California.

We built a customized Shopify setup with AgeChecker, Authorize.net, ShipStation and Avalara integrated from day one.

From concept to live store took under three weeks, with 500+ orders and a 3x return on ad spend in the first month.

420.com came to life with a clear goal: launch fast, launch right, and don't compromise on quality. This was not a temporary website.

It was a solid, scalable e-commerce foundation that could go live quickly, look exceptional and perform from day one, while staying fully compliant in a complex regulatory space.

The challenges

The hemp market moves fast, and timing matters.

1. Under three weeks to launch

The store had to be fully functional in under three weeks, with a smooth customer experience and real operational complexity handled.

2. Multi-state compliance

Products were sold in every U.S. state except California, which meant careful age verification, payments, shipping workflows and tax handling across jurisdictions.

What we built

Flowchart illustrating an e-commerce user journey from entry point with optional location-based gatekeeping, through homepage navigation, product categories, detailed product view, shopping cart options for delivery or pickup, account management, order tracking, checkout process, and order confirmation via email.

1. A customized Shopify build

A focused, cross-functional team with clear ownership across product, integrations and UX built a customized Shopify setup instead of an off-the-shelf theme: a personalized theme aligned with the brand, reusable components and modules for rapid iteration, and clean UX flows designed to reduce friction and increase trust.

2. Key integrations

•AgeChecker for compliant age verification,
•Authorize.net for secure and reliable payments,
•ShipStation to streamline order fulfillment and internal workflows,
•Avalara for automated tax calculation across eligible U.S. states and address validation.

3. Execution and launch

Before deployment, the platform went through thorough QA internally and with the client, validating purchase and checkout flows, compliance and geography edge cases, and the operational handoff for order management. From concept to live store took less than three weeks.
