The challenge
Premier Power Wash 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.
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 tick in the van.
On the phone, the Today tab shows the day’s streets and the houses on each, with a tap to mark each one done. The full round, every client and everything owed are a tab away. All of it works with no signal, and syncs with the desktop later.
