FIND THE REAL PROBLEM

Identify What Is Limiting Your Shopify App

A visible app error may be caused by outdated code, incorrect permissions, failed webhooks, theme changes, or conflicts with another installed app.

We review the complete affected workflow before recommending a solution. This helps us determine whether your app needs configuration, code repair, customization, compatibility updates, or ongoing maintenance.

OUR APPROACH

How We Diagnose and Prioritize Shopify App Problems

We look beyond the visible error to understand how your app interacts with Shopify, your theme, store data, and connected tools. This allows us to recommend a stable solution rather than a temporary patch.

Quick Fix Approach
Structured App Maintenance
— Addresses only the visible error
✓ Identifies the root cause
— Reviews one action or screen
✓ Reviews the complete workflow
— Ignores connected dependencies
✓ Checks apps, themes, APIs and data
— Provides limited testing
✓ Tests affected journeys
— Leaves changes undocumented
✓ Documents completed changes

How We Prioritize the Work

FACTOR 01

Business Impact

We identify which customer, sales or operational workflow is affected.

FACTOR 02

Urgency

Business-critical and sales-blocking issues receive priority.

FACTOR 03

Dependencies

We review themes, APIs, webhooks, app extensions and connected applications.

FACTOR 04

Maintainability

The solution should remain manageable after future Shopify and app updates.
