CUSTOM SHOPIFY APP DEVELOPMENT
WHY BUILD A CUSTOM APP?
FILL FUNCTIONAL GAPS
The App Store doesn't have everything. We build private apps to handle your specific business logic, unique workflows, or complex product customization requirements.
CONNECT YOUR STACK
Need to sync data with a legacy system? We build middleware apps that act as the bridge between Shopify and your ERP, WMS, or proprietary 3PL software.
LAUNCH A SAAS
Have an idea for the next big Shopify App? We offer full-cycle product development—from MVP to App Store submission—helping you tap into millions of merchants.
AUTOMATE OPERATIONS
Stop using spreadsheets. We build internal dashboards and automation tools that trigger background jobs, tag customers, or update inventory without human input.
PRIVATE APP DEVELOPMENT
Secure, internal tools built specifically for your store. Whether it's a custom returns portal or a commission calculator, we extend your Shopify Plus Store capabilities beyond the basics.
PUBLIC APP STORE SAAS
We build apps that meet Shopify's strict submission guidelines. We handle billing API integration, GDPR compliance, and embedded Admin UI using Polaris.
CHECKOUT EXTENSIONS
Customize the checkout experience. We build Checkout UI Extensions to add upsells, custom fields, or loyalty points, essential for Shopify B2B implementations.
API & MIDDLEWARE INTEGRATION
We speak GraphQL. We build robust connectors similar to our own Shopify NetSuite Connector to ensure high-volume data flows smoothly between systems.
HEADLESS BACKEND LOGIC
Running a decoupled frontend? We build the backend functions and API endpoints required to power your Headless Commerce Architecture.
LEGACY APP MIGRATION
Still running on legacy REST APIs or old frameworks? We refactor and modernize your existing apps to use GraphQL and React, ensuring long-term stability and speed.
APP DEVELOPMENT LIFECYCLE
WHY TRUST IWD WITH YOUR CODE?
We don't use outdated methods. We build using the "TALL" stack or MERN stack (MongoDB, Express, React, Node), ensuring your app is fast, responsive, and scalable.
Data leaks kill businesses. We implement OAuth 2.0, rigorous encryption, and GDPR webhooks to ensure your app handles merchant and customer data securely.
We architect apps to handle thousands of requests per minute. Whether you have 1 user or 10,000, our serverless or containerized setups auto-scale to meet demand.
Unlike some agencies that hold code hostage, you own the Intellectual Property. We hand over the Git repository and documentation so you have full control.
