Shopify development and custom apps
Whatever your Shopify needs
Whether you're launching a new Shopify store, improving an existing one, migrating from another ecommerce platform, integrating third-party systems, or implementing AI-powered ecommerce features, we can help through a Fixed Price Project or Continuous Monthly Development.
What we build
Complete Shopify stores
Full store setup including theme implementation, product configuration, payment and shipping setup, third-party integrations, and launch.
Custom Shopify apps
If existing apps don't fit your needs, we provide Shopify app development for checkout logic, specialized workflows, unique product configurations, and proprietary integrations.
Shopify Plus development
Advanced functionality for Shopify Plus stores including custom checkout experiences, wholesale channels, B2B portals, complex automation, and enterprise integrations.
Theme customization
Modify existing themes or build custom themes within Shopify's architecture to keep your store maintainable and update-safe.
Shopify support and Continuous Monthly Development
Send tasks whenever they arise. With Care, everything runs in writing at one fixed monthly price: no estimates to approve, no cost overruns.
Care Plus gives you everything in Care at its own fixed monthly price, plus up to two hours of meetings per month with a Project Manager or any 1902 Software expert (for planning, advice, and technical discussion), up to two ongoing tasks at a time, and up to two developers working on your tasks at the same time.
Care Ultimate is for ongoing engagements, often across multiple systems, that need close collaboration: a fixed price for every task or group of tasks, approved by you before work begins, people with the right expertise added to your project as your needs grow, and meetings with any 1902 Software expert whenever you need them (billed at the going project management rate for the actual time spent).
Typical work includes:
- Bug fixes
- New functionality
- Theme improvements
- Shopify app integration
- Shopify API development
- Performance optimization
- Checkout improvements
- Payment integrations
- Shipping integrations
- Marketplace integrations
- Design improvements
- AI implementation
- WriteText.ai installation and configuration
System integrations
Connect Shopify to ERP, PIM, inventory systems, CRM, shipping providers, fulfillment services, and marketplaces through existing apps or custom integrations.
Fixed Price Projects
For a single, well-defined Shopify project (a new build, a major upgrade) you get one agreed price for the whole thing, fixed before work begins.
Typical projects include:
- New Shopify stores
- Shopify migrations
- Shopify Plus implementations
- Major redesigns
- Custom Shopify applications
- Large integrations
Large projects typically start with a Project Scoping phase at an agreed, prepaid fixed price. The purpose is to precisely define what will be built and to establish the final price. This ensures full clarity for both you and us before development begins.
Taking over existing Shopify stores
Many of our Shopify clients originally worked with another Shopify development company.
We regularly take over existing Shopify stores, review the existing implementation and continue development with minimal disruption to your business.
How we use AI in our work
Our developers, designers, testers, and project managers use modern AI-assisted tools for planning, design, development, and testing. This results in higher quality and faster delivery. Every solution is still thoroughly reviewed, tested, and verified by experienced software developers and testers before delivery.
When you need a custom Shopify app
The Shopify App Store has thousands of apps, but sometimes you need something specific:
- Your business logic doesn't fit standard apps: unique checkout processes, specialized product configurations, or complex pricing rules.
- You need proprietary integrations to internal systems that standard apps can't handle.
- Monthly app subscription costs have grown high enough that custom development is more economical.
- You want functionality specific to your business that gives you a competitive advantage.
Why businesses use Shopify
Fully hosted platform
No server management, security patches, or performance optimization. Shopify handles infrastructure.
Automatic scaling
Handles traffic spikes during sales or seasonal peaks without infrastructure changes.
Fast to launch
Choose a theme, configure products, set up payments and shipping, and start selling.
Non-technical admin
Manage inventory, process orders, and update content without developer help for basic tasks.
24/7 Shopify support
Basic platform questions get handled by Shopify directly.
Shopify Plus considerations
Shopify Plus makes sense for:
Higher transaction volume
Negotiated transaction fees often pay for the upgrade.
B2B or wholesale
Separate pricing for client groups, wholesale portals, complex hierarchies.
Advanced automation
Shopify Flow for complex workflow automation.
Custom checkout
Modify checkout beyond standard Shopify limitations.
Multiple stores
Centralized management across multiple Shopify stores.
AI capabilities for Shopify stores
We can add AI features directly into your store:
WriteText.ai integration
We install and configure WriteText.ai for AI-powered agentic product content generation, helping Shopify merchants generate product descriptions, meta descriptions, page titles, image alt text, and other ecommerce content more efficiently.
Intelligent product recommendations
Personalized suggestions based on client behavior.
Inventory forecasting
Predict demand and get low-stock alerts based on sales patterns.
Client service automation
AI support agents that answer questions and take action, check an order, start a return, escalate to your team with full context. A live example: WriteText.ai, our own product, handles all of its support through an AI voice agent visitors simply talk to.
Improved search
Better understanding of client intent, misspellings, and synonyms.
Conversion optimization
Automated testing of page variations to improve conversion rates.
Our approach
Quick turnaround
Simple tasks typically completed in 24-48 hours.
Team continuity
If one developer is unavailable, another takes over without delays.
Specialized developers
Frontend or backend focus for better quality work.
QA before launch
Every change tested before going live.
Direct communication
Work with a Project Manager who coordinates and keeps you updated.
Fixed Price Projects
Larger projects are delivered as Fixed Price Projects: agreed scope and price upfront, so you know what you're getting before work begins.

Commonly asked questions
Do you provide ongoing Shopify support?
Yes. Continuous Monthly Development is our primary Shopify support service. It allows you to continuously improve your Shopify store without requesting a quotation for every individual task.
Can you take over an existing Shopify store?
Yes. We regularly take over existing Shopify stores developed by other software development companies and continue development with minimal disruption to your business.
When should I build a custom Shopify app instead of using one?
Build custom when your business logic doesn’t fit standard apps, you need proprietary integrations to internal systems, monthly app subscription costs have grown high enough that custom development is more economical, or you want functionality specific to your business that gives you a competitive advantage.
What's the difference between regular Shopify and Shopify Plus?
Shopify Plus offers negotiated transaction fees (beneficial for higher volume), separate pricing for B2B or wholesale client groups, advanced automation through Shopify Flow, ability to customize checkout beyond standard limitations, and centralized management across multiple Shopify stores. It makes sense when transaction volume justifies the upgrade cost or when you need these advanced features.
Can you customize Shopify themes without breaking future updates?
Yes. We modify existing themes or build custom themes within Shopify’s architecture to keep your store maintainable and update-safe. This approach ensures your customizations don’t conflict with theme updates or platform changes.
How do you use AI in your Shopify development work?
AI-assisted, human-verified: every solution is thoroughly reviewed, tested, and verified by experienced software developers and testers before delivery.
What AI features can be added to a Shopify store?
We can integrate WriteText.ai for automated product content, intelligent product recommendations based on client behavior, inventory forecasting with low-stock alerts, AI support agents, improved search with intent understanding, and conversion optimization through automated testing of page variations.
