What we build

The work behind a Shopify Plus store that keeps growing.

Concrete deliverables, not a services list. This is what we get hired for on Shopify Plus.

Custom themes and Online Store 2.0

Built from your brand, not a template. Sections your team can edit without a developer.

ERP and back office integration

Two-way sync of orders, inventory, pricing and product data with STORIS, Epicor and custom systems. No re-keying.

Migration to Shopify Plus

From Magento, BigCommerce, WooCommerce or custom. URLs, SEO, customers and order history carried over.

Checkout and conversion work

Checkout extensibility, promo logic, shipping rules, A/B tested product page and cart changes.

B2B on Shopify

Company accounts, price lists, net terms, catalogs per customer group.

Ongoing development and support

A senior engineer on your account after launch. Backlog worked by revenue impact.

What we shipped

Real stores, real integrations. Here is what we built.

Two sites replatformed to Shopify Plus, STORIS ERP sync built from scratch

Shopify Plus referred Levin Furniture & Mattress to us. We moved two furniture sites onto Shopify Plus and built a custom two-way connector to STORIS so products, pricing, inventory and orders stay in sync between the stores and the showroom floor. Total sales up 83% and conversion rate up 17% since launch. Levin owns the stack.

Free two-day shipping logic, bot traffic cleanup, then a CRO program

Victrola needed free two-day shipping with product-level constraints their previous agency could not deliver, and bot traffic was distorting every conversion number. We fixed both in days, then ran a CRO audit and A/B/n tests and built the winners into the theme.

Magento 2 to Shopify Plus migration with redesign

A full migration off Magento 2 for a made-to-order manufacturer with a deep catalog. Products, customers and SEO carried across, then a redesign built for the way their buyers actually shop.

How it works

From estimate to a senior engineer on your store.

1. You send the form

Store URL and what you need. That is all we ask for up front.

2. A senior engineer reviews it

Not a salesperson. If we need a look inside, we ask for collaborator access.

3. You get a scoped estimate

What we would do, in what order, and what it costs. Written, not a deck.

4. The same engineer does the work

No handoff to a junior team or an offshore bench. You keep everything we build.

No discovery fee and no deck. If we are not the right fit for the work, we will say so in the estimate.

What that's worth in practice.

Success stories

Shopify Plus stores we build and support.

Enterprise ecommerce teams do not hand their platform to just anyone. Here is what we were brought in to fix, what we changed, and where the business ended up.

Senior engineers. In the US. On your account.

No offshore handoffs

The engineer on your call is the engineer on your project. Offices in Sheridan WY, Philadelphia, Charlotte and New York.

We work on merchant-owned code

You keep everything we build. No proprietary layer you have to keep paying for.

We start with what's broken

A replatform is sometimes the answer. It's rarely the first one.

Before you ask

Yes. Most migrations we do land on Plus, but we build and support standard Shopify stores too.

STORIS, Epicor and Oracle so far, plus custom systems. If it has an API or a file drop, we have probably connected to something like it.

Senior engineers based in the US. Offices in Sheridan WY, Philadelphia, Charlotte and New York. No offshore handoffs.

Yes. Everything we build lives in your repo and your store. No proprietary layer you have to keep paying for.

We take on support and ongoing development retainers. Say so in the form.
