Shopify Systems Partner
Shopify & Shopify Plus
Most brands don't
have a traffic problem.
They have a
system problem.

Built for Shopify and Shopify Plus brands doing $50k-$1M+/month.
What we do

What we fix
How we work
Audit first. Implement second. The team that scopes the work writes the code. Two to four engagements at any time.
Trusted Shopify Work
From Shopify Plus storefronts to booking systems, custom product workflows, app integrations, and operational tools. Selected engagements over the last several years.
The Problem
Traffic is not
always the problem.
Most ecommerce teams keep buying more traffic when the real leaks are buried inside the Shopify system. Slow pages, weak product flows, bloated apps, broken checkout logic, and manual operations quietly reduce revenue every day.
High traffic, weak conversion
You are paying for visitors. The store cannot close. Mobile PDPs are slow, the cart is leaking, and the checkout has friction your team has stopped noticing.
Rising CAC, shrinking margins
Acquisition costs keep climbing. The unit economics get tighter every quarter. There is no infrastructure pulling more lifetime value from the customers you already paid for.
Bloated app stack and technical debt
Apps stacked on apps. Theme code patched over the years. No one knows what every app does, what each one costs, or which ones are slowing the store down.
Manual operations behind the scenes
Orders, customer data, inventory, and post-purchase work still rely on spreadsheets and copy-paste. The team scales linearly with revenue instead of compounding.
We build revenue systems,
not just Shopify stores.
For brands past theme
edits and app installs.
What We Fix
Where revenue
quietly leaks inside
Shopify systems.
Six areas growing brands lose revenue inside. Most engagements start with two of these and expand into implementation from there.
Storefront & checkout conversion
Mobile PDP rebuilds, cart and checkout friction removal, Plus checkout extensibility, Functions logic. Where the buying flow loses real revenue.
App stack & theme debt
Audit every app, retire overlap, clean up years of theme patches, reduce monthly app spend, recover store speed.
Retention infrastructure
Klaviyo flow architecture, post-purchase journeys, winback, memberships, repeat purchase triggers. Built to compound LTV.
Custom Shopify apps & workflows
Embedded admin apps, app proxy experiences, configurators, B2B and booking logic, ERP and Klaviyo integrations.
Operational workflows
Order, inventory, fulfilment, and customer data work pulled out of spreadsheets into Shopify-native systems.
International & multi-store
Multi-country architecture, shared theme + GitHub workflow, currency / tax / shipping logic, market-specific merchandising.

Why Signature Works
A Shopify systems partner
The team that scopes also writes the code
No handoff from a sales engineer to an offshore build team. The people on the audit call write the Functions code, the app proxy, the Klaviyo flows, the Liquid.
Every recommendation is judged against the P&L
Unit economics, CAC payback, retention math, operational leverage. We do not ship a recommendation we cannot justify against the actual numbers in your store.
Two to four engagements at any time
No rotating juniors. No project mill. We take on the work where systems-level changes actually move the business and stay involved long enough to make it stick.

Insights
Most Shopify brands don't have a traffic problem. They have a system problem.
When CAC keeps climbing and conversion stays flat, the leak is rarely in the ad account. It is inside the Shopify system. Here is the pattern we see across growing brands.
Why Shopify CRO is an engineering problem, not a design problem.
The conversion leaks we surface most often inside Shopify audits live in PDP architecture, theme performance, and checkout logic. Not button colors.
Retention infrastructure on Shopify: what compounds vs. what decays.
Klaviyo flows, post-purchase journeys, memberships, and segmentation as infrastructure, not one-off campaigns. The architecture decisions that make LTV compound.
