Pressure Wash CRM
Desktop and Android apps for pressure washing businesses
Desktop and phone software for pressure washing businesses, which began as a favour for a friend’s business, Premier Power Wash. It works offline and plans the round itself.
- Windows and Mac app
- Android app
- Works offline
- Syncs between devices

The challenge
It started as a favour for a friend. Premier Power Wash, a family-run business, was running its round on pen and paper: which houses had been cleaned, who had paid and who still owed were all written down and tracked by hand.
On top of that, a new calendar had to be created every fortnight. It was repetitive manual work that took time away from the business itself.
The brief was simply what the app needed to do. The design and concept were ours, and Premier Power Wash tested it and advised on fine-tuning it for the work. None of those problems is unique to one business, so it is becoming Pressure Wash CRM: a product for other businesses in the same industry.
What we built
The apps are built around the way a round actually runs: a fixed two weeks, Monday to Friday. Each client is given a round day once, and the app places them on that day every fortnight, or every four weeks for monthly clients. The calendar is worked out, not written out.
On the desktop, one screen shows the fortnight’s money and every house for the day, grouped by street. One click produces the whole fortnight’s daily sheets, one A4 page per working day, ready to take in the van.
On the phone, the Today tab shows the day’s streets, with a tap to open one and mark each house done. Every client and everything owed are a tab away. All of it works with no signal, and syncs with the desktop later.
Inside the product



Key capabilities
A calendar that makes itself
Fortnightly and monthly clients appear on their round day automatically, with what is not due shown as not due.
The round on the phone
The day’s streets and houses, ready to tick off on site, with directions to the next street.
Every kind of job
Drives, patios, roofs, windows and bins alongside the round, on request or repeating.
Cash, bank and part payments
Record how each job was paid, take part payments, and take money in advance from any client.
Who owes what
Every address that owes money, most owed first, with a payment taken from the same screen.
Missed visits
Any house that was due and not done is flagged until it is dealt with.
Money and profit
Money in, money out, cash and bank totals and profit for each fortnight, with a spreadsheet export for the accountant.
Printed daily sheets
One A4 sheet per working day, with what has been paid in advance marked, so nobody collects it twice.
Offline, synced and backed up
No connection or separate database needed, with syncing between devices over Wi-Fi or USB, an optional PIN lock and automatic backups.
The result
- Pen-and-paper records replaced by one app, with who has paid and who owes visible at a glance
- The fortnightly calendar is worked out by the app, not made by hand
- Tested and fine-tuned with a working pressure washing business
