Regular rounds, one-off commercial cleans, high-rise specialist work — SlotFixer helps window cleaning businesses manage round-based scheduling, route optimisation, customer communication, and automated billing for recurring visits.
If any of these hit close to home, you're in the right place.
You have hundreds of customers on rotating rounds. Keeping track of who's due, who's been done, and who's moved is chaotic.
High winds or heavy rain wipe out a whole day. Rescheduling an entire round and notifying customers takes hours.
Many residential customers still pay cash. Chasing small amounts from dozens of people is not a good use of your time.
You cover an area but don't have an easy way for new customers in that area to find and book you.
Every tool you need to schedule, manage, invoice, and grow — purpose-built for the way window cleaning companies actually work.
Organise customers into rounds — weekly, bi-weekly, or monthly. Schedule entire rounds with one action and track completion as you go.
SlotFixer orders your round into the most efficient route. Walk up one side of the street, down the other — minimum time, maximum coverage.
Tap to check in at each property. Your customer record updates automatically — they know you've been, even if they weren't home.
Bill customers automatically after each clean or on a monthly cycle. Send payment links by SMS — collect online and stop knocking on doors.
Customers skip a clean, request an extra clean, update their details, or pay outstanding balances — all through a self-service portal.
Send 'We're on our way' messages before each visit and 'All done' confirmations after. Professional communication with zero effort.
See which postcodes you cover and where you have gaps. Target new customer acquisition in areas you're already working.
Photograph completed work — especially useful for high-rise or commercial jobs where the client can't see the result from ground level.
Send monthly statements to residential customers with a summary of cleans and outstanding balance. Professional and automated.
See the revenue and time spent on each round. Identify which rounds are profitable and which need restructuring.
“I used to spend Sunday evenings planning my rounds for the week. Now SlotFixer does it automatically, sends messages to my customers, and collects payment while I sleep.”
