Shopify Development Case Study: Rebuilding a Grill & BBQ Brand's Store for Higher Order Value

Kitchen, grills & BBQ equipment (D2C) · United States · 4 months

Project Overview

Industry:

Kitchen, grills & BBQ equipment (D2C)

Service:

Shopify & E-Commerce Development

Objective:

Migrate to a faster, more conversion-capable Shopify platform and increase average order value through bundling and accessory upsells, suited to a high-ticket, infrequent-purchase product category.

Grills and outdoor cooking equipment are a considered purchase — customers research extensively and often buy accessories alongside the main unit, which made the previous platform's limitations a direct revenue problem, not just a technical one.

The Challenge

The brand had strong product quality and real demand, but its existing e-commerce platform was holding back both experience and revenue per order:

The platform couldn't support true product bundling (grill + cover + accessories), so customers bought the main unit alone and upsell opportunities were lost at checkout

Product pages loaded slowly, especially on mobile, where high-resolution grill imagery and spec sheets are essential for a buyer comparing models

The checkout process wasn't optimized for a higher-ticket purchase — no clear reassurance (warranty, shipping timeline, financing options) at the point customers hesitate most

No post-purchase upsell flow existed for obvious accessory add-ons (grill covers, tools, replacement parts)

The site couldn't scale promotional or seasonal campaigns (summer grilling season, holiday sales) without manual, error-prone workarounds on the old platform

The challenge wasn't demand or product quality — it was that the platform itself was capping how much revenue each visitor and each order could realistically generate.

Research & Discovery

Before migrating anything, we looked at how customers were actually buying, and where the current platform was constraining that:

  • • GA4 review of the existing purchase path, identifying where bundle or accessory interest existed in browsing behavior but didn't convert into additional items in cart
  • • Competitor Shopify store audit (other grill and outdoor cooking brands), reviewing bundling, upsell, and checkout patterns already proven in the category
  • • PageSpeed Insights and Core Web Vitals audit of the existing platform, isolating what was specifically causing slow mobile load times
  • • Review of seasonal sales data, to understand the demand spikes (spring/summer) the new platform needed to handle reliably
  • • Customer support ticket review, to identify common pre-purchase questions (warranty, delivery for large items, assembly) that weren't being answered clearly enough on existing product pages

This stage showed the core opportunity wasn't more traffic — it was more revenue per visit, through bundling and a checkout experience built for how people actually buy a grill.

Development & Measurement Setup

Before building, we established a clean baseline so the migration's actual impact could be measured, not assumed:

  • ✓ Shopify Analytics and GA4 configured in parallel during migration, with baseline AOV, conversion rate, and mobile page speed recorded on the old platform first
  • ✓ PageSpeed Insights baseline scores recorded page-by-page (homepage, product pages, checkout) before any rebuild work began
  • ✓ Funnel tracking set up to separate single-item purchases from bundle/multi-item purchases, so the impact of bundling specifically could be isolated
  • ✓ A defined testing window post-launch before drawing conclusions, since e-commerce platform migrations can show temporary dips before settling into a true new baseline

This meant results could be attributed to specific platform and design changes, not just normal seasonal demand fluctuation.

Proven Case Study Impact
Shopify Development: +34% Average Order Value

Higher revenue per order through bundling and upsells the old platform simply couldn't support — without increasing traffic or ad spend.

Shopify Development Strategy

1. Migration to Shopify Plus

Migrated the full catalog, customer data, and order history to Shopify Plus, chosen for its native support of advanced bundling, higher checkout customization limits, and better handling of seasonal traffic spikes than the previous platform.

2. Bundling & Accessory Upsell Build

Built native product bundles (grill + cover + starter accessory kit) directly into product pages, along with a post-purchase upsell step for commonly paired accessories, addressing the single biggest AOV gap identified in research.

3. Performance-First Product Page Rebuild

Rebuilt product page templates with optimized, compressed high-resolution imagery and faster-loading spec sheets, since product visuals are central to a grill purchase decision but had been the main cause of slow load times.

4. Checkout Reassurance & Simplification

Added warranty, shipping timeline, and financing-option messaging directly into the checkout flow at the points research showed customers hesitating, alongside a reduction in unnecessary checkout steps.

What We Did & When

Month 1 — Audit & Baseline
Audited the existing platform's performance and purchase behavior, recorded baseline AOV, conversion rate, and PageSpeed scores, and planned the Shopify Plus migration.
Month 1–2 — Migration & Core Build
Migrated catalog, customer, and order data to Shopify Plus, and built the core bundling and checkout infrastructure.
Month 2–3 — Product Page & Upsell Build
Rebuilt product page templates with optimized imagery and specs, and launched the post-purchase accessory upsell flow.
Month 3 — Launch & QA
Launched the new store after full cross-device testing, with parallel tracking in place to compare against the pre-migration baseline.
Month 4 — Monitoring & Refinement
Reviewed AOV, conversion rate, and page speed against baseline, and adjusted bundle offers and upsell placement based on real post-launch purchase data.
Before After
No native product bundling Bundles (grill + cover + accessories) built into product pages
Slow mobile load times on image-heavy product pages Optimized imagery, faster mobile load times
No post-purchase upsell flow Accessory upsell step added after purchase
Checkout lacked reassurance for a high-ticket purchase Warranty, shipping, and financing messaging in checkout
Platform struggled with seasonal traffic spikes Shopify Plus built to handle peak-season demand
Results

Improvements came from matching the platform and purchase flow to how a high-ticket, considered product actually sells — not from a general redesign.
