Custom Software & App Development

Solve Complex Problems with Code
Sometimes, "off-the-shelf" software just doesn't fit. You find yourself fighting against the tools instead of them working for you. When spreadsheets become unmanageable and subscriptions start stacking up, it’s time to build your own solution.

At Yarn Digital, we specialise in building custom web applications and internal tools that streamline your specific business operations. We don't just write code; we engineer efficiency.

What We Build

1. Client Portals & Dashboards
Stop drowning in emails. We build secure portals where your clients can log in to view their project status, download invoices, or upload files. This reduces admin time by up to 40% and makes your business look incredibly professional.

2. SaaS (Software as a Service) Products
Have an idea for the next big app? We help startups in Belfast take their concept from "napkin sketch" to MVP (Minimum Viable Product). We build using scalable technologies like React, Node.js, and Supabase, ensuring your app can handle 10 users or 10,000.

3. API Integrations & Automation
Your software shouldn't live in silos. We write custom scripts to connect your different tools (e.g., connecting your Xero accounting to your Shopify store, or your CRM to your email marketing). If it has an API, we can make it talk.

Our Development Standards

• Security First: We build with enterprise-grade security practices, ensuring user data is encrypted and GDPR compliant.

• Scalability: We write clean, modular code that is easy to expand. You won't need to rebuild from scratch when you grow.

• User Experience (UX): Internal tools shouldn't be ugly. We apply the same high design standards to our software as we do to our public websites.

Frequently Asked Questions

Do I own the code?
Yes. Once the project is paid for, the Intellectual Property (IP) belongs 100% to you. We don't hold your code hostage.

How long does a custom app take?
It varies wildly. A simple internal dashboard might take 4–6 weeks, while a full SaaS platform could take 3–6 months. We work in "Sprints" so you see progress every two weeks.

Can you take over an existing project?
Yes, provided the code is relatively modern. We offer a code audit service to assess the health of your current software before we begin work.
