How We Work
Our proven process.
A conversion-focused store build needs more than theme setup. It needs structured UX, the right integrations, and clean implementation throughout the funnel.
- 01
Discovery & Strategy
We review your offer, customer journey, competition, and existing data to define the conversion goals the build should improve.
- 02
Design & UX
Storefront layouts, product detail pages, cart behavior, and mobile touchpoints are designed around how your customers actually buy.
- 03
Shopify 2.0 Development
We build custom Liquid sections and templates that are flexible in the editor without compromising front-end quality.
- 04
Integrations & Automation
Email, payments, subscriptions, reviews, analytics, and app setup are configured deliberately around the store workflow.
- 05
QA, Speed & Launch
Cross-device testing, performance checks, and analytics validation are completed before a phased rollout.
Why GAP3 in France
Why businesses choose GAP3.
Checkout Expertise
We treat checkout as the highest-leverage part of the store and optimize trust, flow, and upsell opportunities accordingly.
Data-Driven CRO
Heatmaps, recordings, analytics, and testing are used to improve conversion rather than relying on design preference alone.
App Stack Discipline
We recommend the smallest, highest-impact app setup possible and avoid piling on complexity where custom code is cleaner.
Mobile-First Commerce
Thumb zones, tap targets, fast product galleries, and native-feeling mobile flow are treated as non-negotiable.
Post-Launch Iteration
Launch is the starting point for CRO work, campaign support, and refinement based on store performance.
