What is included in a Shopify theme project?

Every project ships against the same delivery baseline. Scope changes the template count and the complexity, not the standard.

Storefront build

  • Custom Shopify 2.0 theme, or a hardened Dawn build
  • Pixel-accurate Figma-to-Liquid development
  • Reusable section and block library your team can rearrange
  • Mobile-first responsive build, tested on real devices
  • Handover documentation and team training

Conversion and automation

  • Metafield-driven PDPs: variants, bundles, subscriptions, sizing
  • Collection filtering, search, and merchandising rules
  • Optimized cart, upsell slots, and checkout extensions
  • A/B-test-ready sections so you can keep optimizing
  • Shopify Flow automations for orders, inventory, and tagging

Three ways to work with BrillMark

Which model fits depends on how much of the design and platform work is already settled.

Full store design and build

Concept and Figma design through Liquid development, automation setup, QA, and launch.

Figma-to-Shopify development

You bring the approved design. We build it as a responsive, pixel-accurate Online Store 2.0 theme your merchandisers can edit.

Replatform and theme rebuild

We audit the current store, migrate products, customers, and content, rebuild the theme, and validate parity before cutover.

Conversion first

Why CRO experience changes the build

Layout decides conversion rate, not just appearance. Each theme starts from patterns that have already won in live tests.

Add-to-cart on PDP layout

Variant selection, price clarity, and shipping proof placed where our test history says they carry the decision.

โˆ’_._s

Median LCP on mobile

Lean Liquid, deferred app scripts, and image discipline. On mobile commerce, every second of LCP shows up in the conversion rate.

Checkout completion

Cart and upsell hierarchy built from patterns that survived testing across apparel, supplements, and home goods.

Sections are isolated and events are instrumented, so your team ships test variants after launch without a developer rewriting the template.

Ask for the test log
  • Product and inventory sync from your ERP, PIM, or supplier feeds
  • Order routing, fraud holds, and fulfillment handoff via Shopify Flow
  • Automated collection and tagging rules for merchandising
  • Discount and bundle logic with Shopify Functions
  • Abandoned-cart, win-back, and post-purchase flows in Klaviyo
  • Returns, exchanges, and support ticket triage
  • Scheduled reporting into Sheets, Looker, or your warehouse
Process

How the two-week cycle is spent

Four stages, on a fixed calendar. AI-assisted where it is faster, senior-reviewed where it matters.

STEP 01 Days 1โ€“2

Discovery

We review your catalog, templates, apps, integrations, and revenue goals, then fix the scope and the price.

STEP 02 Days 3โ€“4

Audit

AI-assisted crawls flag funnel friction, script bloat, and migration risk. Our specialists turn that into the build plan.

STEP 03 Days 5โ€“12

Build and automate

Agentic workflows write the theme and the automations. A senior engineer reviews and approves every commit.

STEP 04 Days 13โ€“14

Launch

We publish the theme, verify tracking on live orders, and hand over documentation and training.

Client stories

What Our Clients Say About Us

Teams who handed us their storefront and their test roadmap, in their own words.

1:30
I canโ€™t imagine any other companies out there in a similar situation where we are that couldnโ€™t benefit from the services that BrillMark offers.
1:10
Finding competent professionals to bring conversion research ideas to life without breaking their websites was challenging โ€” until I found BrillMark. A group of technical A-players with whom anyone serious about CRO and experimentation should work.
Custom or Dawn

Should you build a custom theme or harden Dawn?

Dawn is the faster, lower-cost start. A custom theme earns its cost when the PDP logic outgrows what Dawn models natively.

Dimension Hardened Dawn Custom 2.0 theme
Time to launch Around two weeks Two to four weeks depending on logic
Starting cost $1,499 $4,900
PDP complexity Standard variants and options Bundles, subscriptions, B2B pricing, custom metafield logic
Merchandiser control Familiar Dawn editor with added custom sections Purpose-built section and block library
Upgrade path Inherits Shopifyโ€™s Dawn releases Maintained by you or by us
Best fit Standard merchandising, first storefronts Complex catalogs and Shopify Plus
Why choose us

Three reasons teams pick BrillMark

We are a testing company first

Most Shopify shops build what the design says. We have run 45,000+ experiments, so we can tell you which parts of your design are likely to cost you revenue before a line of Liquid is written.

Agentic build, senior review on every commit

AI writes the repetitive Liquid and the automation scaffolding, which is how two weeks is possible. No commit reaches your store without a senior engineer approving it.

You own the theme outright

No proprietary page builder, no license, no monthly app stack standing in for logic. You get the repository, the documentation, and a team that can edit it without us.

Questions

Shopify theme development FAQ

It is the build of a storeโ€™s storefront layer in Liquid, JSON templates, and sections. A custom Online Store 2.0 theme controls the product, collection, and cart experience directly in code, rather than depending on a stack of paid apps for merchandising, layout, and page building.
Projects start at $1,499 USD for a hardened Dawn build, $4,900 for a custom Online Store 2.0 theme, and $7,500 for a replatform. Every quote is fixed before development begins. Final cost depends on template count, catalog size, integration depth, automation scope, and migration volume.
Yes, for a standard scope: up to eight templates, a settled design, and a catalog already in Shopify. Larger catalogs, ERP integrations, and B2B pricing logic extend the cycle, and we tell you that at quote time rather than at week two.
We are. Agentic workflows write the repetitive Liquid and automation scaffolding, and a senior engineer reviews and approves every commit before it reaches your store. You get the same warranty and the same repository you would from a fully hand-written build.
Completely. You get the Git repository, the theme files, the Flow and Functions configuration, and handover documentation. There is no proprietary page builder, license, or monthly fee attached to anything we build.
Yes. Figma-to-Shopify is our most common engagement, and we deliver white-label for agencies. We work from your approved design, flag any pattern our test history suggests will underperform, and build what you decide.
