Software built for jewelry retailers

Tools for jewelry retailers: serialized inventory and marketing attribution. Explore what each tool does, with plans and pricing available from its product page.

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.

Explore each tool on its own product page. Serial Manager is a standalone Shopify app, and Felix Attribution connects marketing activity with sales records. Plans, pricing and availability vary by product.

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, customer records integrations. Our tools fit into what you already use.

Plans for Each Tool

Pricing and available plans vary by product. Visit each tool’s page for its current options, limits and setup details.

Actively Maintained

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