One place for the whole job.
Bookings, customers, crew and paperwork in one app — not five subscriptions and a group chat.
System 04 Apps
The tools your crew runs on. Built around how you actually work.
Customer portals, booking flows, job boards and dashboards — software shaped to your business instead of you bending to someone else’s. Fast on a phone, simple enough to use on day one.
What it does for you
What changes when it’s running.
Customers serve themselves.
A portal where clients book, pay, sign and check status without calling you.
The business at a glance.
A live view of what’s booked, what’s owed and who’s where.

A clickable preview on your phone before any production code. Change anything.

One build fee, then own it outright or let us run it. The price comes in your proposal, after the call — never off a menu. How ownership works →
Fair questions
Asked on almost every call.
Why not off-the-shelf software?
Off-the-shelf works until it doesn’t fit — then you pay for features you don’t use and work around the ones you need. A custom app runs your process exactly.
Do I own it?
Yes. The source code, every account and every login are yours. Run it yourself or let us run it.
Can it connect to what I already use?
Usually — calendars, payments, accounting and email. We confirm every connection on the call.
How long does a build take?
It depends on the scope. Your report lays out the stages and the timeline before you decide anything.
