I'm Christian Murphy and I build custom software for small businesses.

Software built around how your business already works.

Mostly that's business systems, Windows apps, web tools and websites. I do all the work myself, which means the person you email is the one who builds it and looks after it later.

A day in Ledgeline.

Ledgeline is one of my own products. It looks after bookings, deposits, invoices and reminders for a small business, and the screens below are from the first business running it.

01 / Booking
A booking works out the price and deposit.
Fill it in once and the deposit, balance and due dates are set, then the customer gets a link to check the details and pay.
Price and deposit worked out
Plate 01 / New booking
02 / Deposit invoice
The deposit invoice comes from the booking.
It stays linked to that booking for good, so you never have to match payments up by hand.
Deposit on the invoice
Plate 02 / Deposit invoice
03 / Reminder goes out
Reminders go out without anyone sending them.
Ledgeline lines them up when the booking is made and each one goes out on the right day.
Due today and queued
Plate 03 / Outbox
04 / Run the day
Staff run the day from their phones.
Today shows the next jobs and anything that needs attention, and it keeps working when there's no signal.
Alerts and next jobs
Plate 04 / Phone view

That business flies pets on charter aircraft and a courier version is next.

It's only a demo so nothing gets sent to anyone.

What happens when you get in touch.

First chat

You tell me how things run now and what you'd like to fix, and we work out what's worth building.

A written quote

Then I send a written quote so you know the cost before anything gets built.

Support afterwards

When it's finished I hand it over properly and I'm still around if anything needs looking at.

Other things I've built.

There's a Windows app for people who record games and a few free web tools you can use right now.

Substrike

Point it at a folder of game recordings and it writes the captions and works out who's speaking. It also finds the loud moments and cuts clips for Discord, TikTok or Shorts. Everything runs on your own PC so the footage stays with you and nothing is charged by the minute.
