Custom Excel spreadsheets built to last — not just to work once.
Most business spreadsheets are built under pressure and never properly engineered. We design and build custom Excel spreadsheets for New Zealand businesses that are structured, validated and maintainable — so they keep working as your business grows.

Sound familiar? These are the issues NZ businesses bring to us most often.
Spreadsheets that break when someone adds a row or changes a formula
Multiple versions of the same file circulating across teams
Hours spent manually copying and pasting data between sheets
No input validation — anyone can type anything anywhere
Reports that take half a day to update instead of minutes
Critical business logic locked in one person's head (or one cell)

Excel spreadsheet development across New Zealand
We work with businesses throughout New Zealand — Auckland, Wellington, Christchurch, Hamilton, Tauranga and beyond. Most projects are delivered remotely, with on-site visits available for Auckland-based clients. Whether you need a simple tracker or a complex multi-sheet reporting system, we scope and deliver to your timeline and budget.
Frequently asked questions
How long does a custom spreadsheet take to build?
Most projects take one to three weeks depending on complexity. A simple tracker might be two or three days. A full reporting pack with multiple data sources and automated outputs is typically two to four weeks.
Can you improve an existing spreadsheet rather than build from scratch?
Yes. We regularly take over existing spreadsheets, restructure them for stability and performance, and add missing functionality. We will always advise whether a rebuild or enhancement is the better investment.
Will the spreadsheet work on our version of Excel?
We build to match your environment. If you are on Excel 2016, Microsoft 365 or a mixed environment, we test and confirm compatibility before delivery.
Do you work with businesses outside Auckland?
Yes. We work with businesses across New Zealand including Wellington, Christchurch, Hamilton and Tauranga. Most spreadsheet development is delivered remotely with video calls for discovery and review.
What happens if we need changes after delivery?
We provide a short support period after every project. For ongoing changes and enhancements, we offer a support retainer or quote individual change requests.
