Loyalty credits

Custom app for credit-only checkout

Regal Crown Club members pay for rewards with their loyalty credits, and Shopify's checkout could not take an order paid only in credits. We developed a custom app that applies the credits and discounts on the cart page and still charges the right shipping cost.

Drop calendar

Custom drop calendar and purchase limits

Swag Golf releases limited products in timed drops. We created a drop calendar driven by collection data and an add-to-cart limit on each product, so one buyer cannot take more than their share.

Kajabi

Custom app connecting Shopify and Kajabi

Taking Cara Babies sells classes through Kajabi and Shopify. We developed a custom app that gives parents access to the class in Kajabi when they buy and blocks them from buying the same class twice.

GraphQL

The API Shopify requires for new apps

Since April 2025, new public apps on the Shopify App Store must use the GraphQL Admin API, and the REST Admin API is now legacy. We develop new custom API integrations on GraphQL.

"We partnered with Shero for the development work on the SWAG site. The dev was highly nuanced, specialized and complex. The Shero team went above and beyond from the jump. They were collaborative, organized and professional, consistently setting expectations clearly and usually exceeding them."

Matt Kaminsky, Co-founder and Managing Director, Strike 2

When the App Store has the wrong answer

Nearly every Shopify store uses the same themes and the same apps, and for most of them that is the right call. It stops being the right call at a specific moment: usually when an app does ninety percent of what you need and the last ten percent is the part your business actually depends on. That is where paying for custom work becomes cheaper than working around the gap forever.

Why brands go custom with Shero

Custom development is worth it when the team understands both eCommerce and engineering. Here is how Shero approaches projects that go beyond standard configuration.

01

One team from scoping to launch

Strategy, design, development, QA and launch are handled by one team, and that team stays on after go-live. You never explain your business twice, and nobody can tell you the spec meant something else.

02

You own what we create

The repository, the documentation and the deployment access are yours at handover, and any competent Shopify developer should be able to pick it up. We write it that way deliberately. An app only we can maintain is a reason to keep paying us that we would rather not rely on.

03

Integrations scoped from day one

Custom app and theme development is scoped together with integration requirements. ERP integration requirements shape the data model and API design of custom apps. Developing them separately produces conflicts that are expensive to resolve later.

04

Whether you actually need Plus

Custom theme work and most app integrations work fine on standard Shopify. Plus is what you need for checkout changes, unlimited B2B catalogs, several storefronts under one admin, or Flow automation at volume. If you do not need those yet, we will say so before you upgrade.

05

Made to your spec

Every custom project starts with your business requirements: how you sell, who you sell to, which systems you use, and what the standard platform cannot do. We do not adapt your business to fit a theme. We create the store to fit your business.

06

We are still here in year three

After launch, Shero stays on for post-launch support, Shopify Plus upgrades, CRO, SEO, and paid media as the business grows. Benchmade, STX, and Painful Pleasures have been Shero clients for multiple years after their initial build.

Baby Sleep Courses

Taking Cara Babies

Since 2013, Taking Cara Babies has helped parents build better sleep routines. With a custom CMS holding back growth and plans to sell physical products, they chose Shopify Plus and brought in Shero Commerce to handle a complex migration, unifying physical and digital sales on one platform.

Industrial Safety Solutions

Justrite

JustRite Safety Group is a leading manufacturer of workplace safety products with roots going back to 1906. The brand partnered with Shero to merge four separate Magento stores into a single multi-store megasite, allowing customers to shop across all brands with one shared cart. Organic traffic doubled almost immediately after launch and continued to grow steadily over the following six months.

Leadership Education

CCL - Center for Creative Leadership

Shero moved the Center for Creative Leadership, a global nonprofit, from iApps to Magento 2. We integrated Microsoft Dynamics 365 and VitalSource, set up international selling, and improved the store and checkout on every device.

Candy and Party Favors

Just Candy

Just Candy sells personalized candy and party favors from a catalog of more than 16,000 SKUs. On VTEX, the brand had a rigid and expensive tech stack, a dip in sales caused by user experience issues, and site management that depended on heavy custom development. Shero moved the full catalog to Shopify and kept personalization and performance intact. Indexed pages increased 66% after the migration.

Just Candy

Built to load fast and stay fast

Every build goes live with the speed and code standards that keep the store fast after launch.

  • Core Web Vitals

    Templates built and tested to pass on mobile.

  • Fewer apps

    Features built into the theme when an app would slow the store.

  • Clean code

    Online Store 2.0 sections your team can edit without a developer.

  • QA

    Every release tested on desktop, mobile and checkout.

Most custom Shopify projects take 6 to 16 weeks. Let's talk about yours.

Process

How a custom Shopify development project works

Custom work starts with a written spec, so everyone knows what gets made and why.

  1. 01

    Discovery

    We go through how you sell, which systems must stay connected and what the platform cannot do out of the box.

  2. 02

    Technical design

    We decide the data model, which logic becomes a Shopify Function or app, and what the theme owns.

  3. 03

    Develop blocks

    Theme, app logic and integrations get developed in two-week blocks, with something you can click through at each review.

  4. 04

    Testing and UAT

    We test with your actual products, prices and customer records, including the edge cases your team flagged. Your team then tests in BugHerd and signs off.

  5. 05

    Go live

    We launch with a rollback plan ready, hand over the documentation and stay on for support.
