Web apps that extend Excel — or take you beyond it.
We build dynamic web applications using technologies like Java and cloud databases — including the Google Cloud ecosystem — to extend Excel functionality or migrate users from spreadsheet applications into full multi-user web apps. Browser-based, any device, with the option to keep Excel connected for reporting.

Signs it is time for a proper web application.
An Excel application that works for one power user but cannot support concurrent multi-user access
Field or mobile staff who need the same data as the office team without opening a desktop workbook
Spreadsheet logic that has outgrown Excel and needs a proper application layer with roles and audit trails
Business processes trapped in a single workbook with no way to expose them securely to customers or partners
Need to keep Excel for reporting while moving day-to-day operations into a browser-based system
IT wanting cloud hosting, managed databases and modern deployment — not macros emailed around as attachments
Web application examples
Hybrid and full web solutions delivered for New Zealand organisations.
Valet Parking Hybrid App
Pullman Hotel Auckland: mobile web apps for parking attendants connected to a cloud SQL database, with Excel remaining the admin analytics console — the same data, two interfaces.
Claims Analysis Platform
NZI: a web application for collecting claims data into MS SQL, feeding management dashboards while Excel remains available for deeper analyst work on the same dataset.
Range Planning Multi-User System
Fashion retail: buyers kept familiar spreadsheet workflows while a shared cloud database replaced fragile linked workbooks — enabling concurrent planning and POS integration.
Field-to-Office Workflow App
Browser-based capture for in-field teams with role-based access, cloud storage and optional Excel exports for finance and management reporting.
How we work
From spreadsheet pain point to production web application.
Architecture and scope
- Map current Excel or spreadsheet processes and who needs access
- Decide: extend Excel, hybrid (web + Excel), or full migration off Excel
- Choose stack — Java/.NET, cloud database, Google Cloud or similar — to match your IT environment
Deliverable: Architecture recommendation, user roles and delivery milestones.

Web applications across New Zealand
We design and build web applications for businesses throughout New Zealand — Auckland, Wellington, Christchurch and beyond. Projects are typically delivered remotely with regular demos. Whether you need to extend Excel with a browser front-end or migrate fully to a cloud-hosted application, we keep the path practical and aligned with how your team already works.
Frequently asked questions
How is this different from Enterprise Excel Applications?
Enterprise Excel Applications keep Excel as the primary application — governed workbooks, VBA and optional SQL hybrids. Web Applications are browser-based systems built with web technologies (Java, cloud databases, Google Cloud and similar) that either extend Excel or replace spreadsheet apps for multi-user, any-device use.
Can you extend our existing Excel tools rather than replace them?
Yes. A common pattern is a web front-end for capture and operations, with Excel remaining connected for analytics, budgeting or offline reporting. We design the split so each tool does what it does best.
What technologies do you use?
Depending on the project we use Java, .NET, React and other modern web stacks, with cloud databases and platforms such as Google Cloud. We match the stack to your IT standards, security requirements and existing systems.
When should we migrate off Excel entirely?
When you need concurrent multi-user editing, mobile or customer-facing access, strong role-based security, or data volumes and workflows that Excel cannot reliably support. We help you decide based on users, risk and cost — not a one-size-fits-all rebuild.
Do you host the applications?
We can deploy to your cloud account (for example Google Cloud) or work with your IT team on hosting you already use. Ongoing support and enhancement retainers are available after go-live.
