Enterprise-grade Excel applications for large NZ organisations.
Large organisations often need the flexibility and familiarity of Excel combined with the stability, access control and data management of a proper application. We design and build enterprise Excel applications for New Zealand organisations — pure VBA, cloud-hybrid or database-connected — that hold up under real enterprise conditions.

The gaps between spreadsheet tools and enterprise requirements.
A spreadsheet that started simple has grown into a mission-critical application with no governance
Multiple teams using different versions of the same tool — with no single source of truth
No access control — anyone can change any part of the spreadsheet, including the logic
Excel used to do something a proper application should do, but a rebuild isn't justified
Existing Excel applications that need SQL back-ends as data volumes grow beyond Excel's limits
A tool that works in one department but cannot scale to a business-wide deployment

Enterprise Excel development for large NZ organisations
We have designed and delivered enterprise Excel applications for some of New Zealand's largest organisations — including Contact Energy, AMP Financial Services and NZI Insurance. We work with IT teams, business analysts and end users across Auckland, Wellington, Christchurch and other New Zealand locations. Most delivery is remote with on-site engagement for discovery and deployment.
Frequently asked questions
What makes an Excel tool an "enterprise application"?
An enterprise Excel application has structured access control, validated inputs, error handling, logging, documentation and a deployment mechanism. It is designed to be used by many people reliably over time — not just one person who built it.
When should we consider a VBA + SQL hybrid rather than pure Excel?
A VBA + SQL hybrid is appropriate when data volumes exceed Excel's reliable range (typically 100,000+ rows for performance-sensitive operations), when you need a central data store multiple users access simultaneously, or when other systems need to read from or write to the same data.
Can enterprise Excel applications be deployed via SharePoint?
Yes. SharePoint is a common deployment platform for enterprise Excel applications in NZ. It provides a familiar, IT-managed location, integrates with organisational security and access control, and allows controlled distribution across teams.
How do you handle access control in Excel applications?
We implement sheet and workbook protection, hidden admin functionality, user-level access via VBA login routines and, in SQL-hybrid applications, database-level access control. The appropriate level depends on the sensitivity of the data and the number of users.
What does ongoing support look like after delivery?
We offer a support retainer for enterprise applications — covering bug fixes, minor enhancements and version updates. For larger enhancements, we quote separately. We aim to build solutions that your own team can operate and maintain, with clear documentation.
