I will build custom business automation tools in google sheets
James H
About this gig
Custom Google Sheets & Apps Script Systems Built for Small Business
Does your business run on spreadsheets that are disorganised or just not quite right for how you work?
I build custom tools in Google Sheets and Apps Script automating the repetitive parts and creating systems that fit your business, not the other way around.
Why Sheets & Apps Script?
Everything runs in your Google account no subscriptions, nothing new to learn, your data stays yours, no lock-in.
What I can build:
- Lead, job, or task trackers
- Invoice/quote generation
- Custom dashboards & reports
- Automated emails & reminders
- Multi-sheet workflows
- Full web app interfaces
If you're doing something manually and repetitively in a spreadsheet, there's a good chance it can be automated.
I built these tools because I needed them myself- practical, no-nonsense, built to get used. I work full-time alongside this, so I'm upfront about realistic timelines.
Message me with what you're wanting to achieve, and I'd be happy to confirm scope before you order.

Hi, I'm James, based in NZ.
I build custom Google Sheets & Apps Script tools for small businesses who want something practical, without dedicated software costs.
Before this, I worked in transport, trades, mechanics, and sales — so I understand the businesses I build for, and what actually needs tracking vs what's just extra admin.
I started building tools because I needed them myself and couldn't justify subscriptions. Everything runs in Google Sheets — nothing new to learn, and your data stays in your account.
I work full-time alongside this, so I'll be upfront about realistic timelines.

FAQ
What information do you need from me to get started?
A description of what you're trying to achieve, your business type, and how you currently do this (a messy spreadsheet or a description of your process is fine). The more detail upfront, the more accurate I can be with scope, timeline, and which package fits best.
How long will it take?
Basic automations typically take 2-3 days. Standard systems usually take 5-7 days. Premium web app builds may take 7-10 days. I'll confirm a realistic timeline once I understand what you need, and flag early if something looks like it needs more time than the package allows.
Do I need any special software?
No — everything runs in Google Sheets and Google Apps Script, which are free with any Google account. If you can use Google Sheets, you'll be able to use what's built for you.
Will you have access to my data?
No. Everything is built to run inside your Google account. For Standard and Premium packages, I'll need temporary access to set things up, but I don't retain access afterward and your data never leaves your account.
What if my project doesn't fit neatly into one of the packages?
Send me a message before ordering with details of what you need. I'll let you know honestly whether it fits a package as-is, needs a custom quote, or should be broken into phases.
What if I need changes after delivery?
Each package includes a set number of revisions for refining what was originally agreed. If you'd like to add new features beyond the original scope, I'm happy to quote separately — or you can add the 'Additional revision' extra.
Can you make changes to my system later on, or add new features?
Yes — feel free to message me anytime after delivery if you'd like changes or additions. I'll quote separately for any new work.
How quickly will you respond to messages?
I work full-time on a shift roster alongside this, so response times can vary — usually within 24 hours, sometimes sooner. If I'm mid-project with you, I'll let you know if a busy stretch of shifts might affect message timing, so there are no surprises.
