Systems That Run Your Operations. Not Just Your Website.
Most software projects end with a handover document and a wave goodbye. That is not how we engage.
We design and build platforms that sit at the core of how your business runs. Customer portals, ERP systems, internal workflow tools and API integrations. Engineered for the complexity of real operations, not a generic brief.
Whether you are starting from nothing, modernising a system that is slowing you down or scaling a platform that has outgrown its architecture, we stay involved through the entire lifecycle.

Custom ERP, APIs and Everything Between
These are the capabilities we bring to every custom web engagement. Each one is grounded in real project experience across our client base.
How We Approach Every Web Project
We do not start building until we understand the problem.
Every technical decision on a Collatzinc engagement traces back to something operational you told us in discovery.
Map Operations
Focused sessions with your team to map workflows, users, existing systems and failure points. Scope, timelines and success metrics are agreed before a single line of code is written.
Build Systems
Iterative delivery with staging environments and client review at every milestone. You see progress throughout. Nothing reaches production without your sign-off.
Run and Optimise
After launch we stay in. Performance monitoring, feature releases, security updates and scaling support. The handover document is not the end of the engagement.
Built with Tools Your Platform Will Still Depend On in Five Years
These are the technologies we use across our custom web and ERP projects. Chosen for stability, ecosystem maturity and long-term support. Not recency.

Custom Cloud-Native ERP for a National Food Service Operation
- Cloud-Native
- Full-Stack
- Custom ERP
- Ireland
A leading institutional catering provider needed a technology partner from day one. Not a vendor to hand a brief to. Their operation spans schools, healthcare institutions and correctional facilities across Ireland, coordinating high-volume meal ordering, kitchen management and institutional billing in real time.
We designed and developed the full-stack cloud-native ERP that now runs their entire national operation. Real-time ordering and demand forecasting, multi-platform smart kiosk management, AI-driven waste reduction and third-party institutional integrations. The platform has scaled with the business from 20 sites to over 100 without an architectural rebuild.

Is This the Right Fit?
Custom web development works best when there is a real operational problem that off-the-shelf software cannot solve cleanly
You are a good fit if
- Your operations have outgrown your current platform
- You are running critical processes on spreadsheets or disconnected tools
- You need a platform built to your workflow, not a workflow built around a template
- You have tried a SaaS product and found it doesn't quite do what you need
- You are modernising a legacy system without disrupting live operations
What to expect from us
- A senior engineer on your discovery call, not a salesperson
- Fixed scope or phased delivery, clearly agreed before work begins
- Weekly progress updates and a shared communication channel throughout
- Code you own, documentation your team can work from
