Free Software for Jewelers

Software Built for Jewelry Retailers

We build the tools that jewelry retailers actually need. Lead generation, inventory tracking, marketing attribution. Each one solves a real problem, works out of the box, and doesn't require a six-month implementation.

Our Tools

Three Tools. Three Problems Solved.

Inventory Tracking

Serial Manager

A Shopify app for serialized inventory. Assign serial numbers during fulfillment, track warranties, prevent fraud, and manage bulk imports. Built for jewelers who sell pieces with unique identifiers and need clean records without spreadsheets.

Marketing Attribution

Felix Attribution

Track online ads to in-store sales. Device fingerprinting connects a walk-in purchase to the exact Google or Meta ad that drove it. Prove ROAS on foot traffic when cookies and last-click attribution fall short.

Why a Marketing Agency Builds Software

We run paid ads, SEO, and web development for jewelry retailers every day. That means we see the same problems over and over. A jeweler who can't track which ad drove a walk-in sale. A Shopify store with no way to manage serial numbers. A website that collects "contact us" submissions from people who never pick up the phone.

When the same gap shows up across enough clients, we build a tool to close it. Not a generic SaaS product repurposed for jewelry. Software designed from the start for retailers who sell high-value, one-of-a-kind pieces. Every tool we ship comes from a real problem we watched a real jeweler deal with.

You don't need to be an H&CO client to use them. The Ring Builder is free. Serial Manager is a standalone Shopify app. Felix Attribution works with any ad account. Use one, use all three, or just browse. No sales pitch required.

What All Our Tools Have in Common

Built for Jewelry

Not repurposed from another industry. Every feature, field, and workflow is designed for retailers who sell rings, watches, and fine jewelry.

Your Data Stays Yours

No shared marketplaces, no lead reselling, no third-party access. Your customer data belongs to you. Export, integrate, or delete anytime.

Set Up in Minutes

No six-month onboarding. No consultant required. Each tool works out of the box with minimal setup, so you can start using it the same day.

Works With Your Stack

Shopify, WordPress, Squarespace, custom builds. Webhooks, CSV exports, CRM integrations. Our tools fit into what you already use.

Free or Affordable

The Ring Builder is completely free. Every other tool is priced for independent retailers, not enterprise budgets.

Actively Maintained

We use these tools with our own clients. They get updated regularly based on real feedback from working jewelers.
