Window cleaning round software, free for your first 5 customers
A window cleaning round is a beautiful business when it runs itself. Bookso is the round software that schedules every customer, sends the heads-up, and keeps the cash coming through without the chasing.
Free for your first 5 customers. No card required.
Your customer list
Every customer in one place.
Auto-scheduled reminders
Service due? We send the nudge.
They tap, you book
Customers book themselves in 30 seconds.
Set each customer up on the interval they pay for: 4-weekly, 6-weekly or 8-weekly. Bookso schedules the next visit automatically and lines up the round so you can see your week at a glance. When the day comes, your customer gets a quick email reminder so the gate is unlocked and the car is moved off the drive.
The free plan covers your first 5 customers, which is enough to test it on a small patch of your round before moving the rest across. There is no card required and no time limit. When you are ready, Pro is £14.99/month for unlimited customers, the CSV importer for moving a full round in one go, and removal of the Bookso footer from your booking page.
Bookso is built for the way window cleaning actually works. You can set a price per customer, mark visits as done from your phone, and the next visit is scheduled automatically based on the interval. If a customer wants to skip a wash or move to a different interval, they can do it from the booking link without needing to ring you.
There is no contract. Cancel from your account settings whenever you like. The aim is simple: less admin, fewer missed cleans, more time on the ladder.
The problem
Rounds leak. It's the quiet killer of window cleaning businesses. A clean gets missed because it rained on the day and never got rescheduled. A customer can't quite remember when you're next due, so they book someone else 'just for this once'. Someone moves house and you find out three visits later. A customer goes to the gate expecting you and finds nobody there. Each of those is a small thing on its own, and each one drops a customer off the round.
A leaky round means you spend every quiet week canvassing new streets just to stand still. That's fine when you're building, but exhausting when you're supposed to be established. The maths is brutal: lose one customer a week to leaks and it takes 50 canvassed doors a week just to break even.
The fix isn't more canvassing. It's making sure every customer you've already got knows when you're coming, gets a heads-up they can act on, and can rebook or skip in one tap without needing to ring you.
How Bookso works for window cleaners
You set each customer's frequency once: 4-weekly, 6-weekly, 8-weekly, monthly, or whatever they've agreed to pay for. Bookso schedules the next visit automatically and lines up the whole round so you can see your week at a glance.
When the customer is due, they get an automatic heads-up from your business name - a text-the-night-before style reminder so the gate is unlocked, the car is moved off the drive and the side access isn't blocked. Fewer wasted trips, fewer 'sorry we missed you' cards.
You mark each visit done from your phone as you leave. The next visit is scheduled automatically based on that customer's interval - not from an ideal date on a spreadsheet, but from the actual date you cleaned. So if the round slips by a week because of weather, everyone stays in the right cycle rather than piling up.
Add-on jobs work the same way. Conservatory roof clean once a year? Add it as its own job type on a 12-month interval. Gutter and fascia wash every 12 months? Same. UPVC clean every 6 months? Same. Each add-on has its own price and its own reminder that goes out at the right time - the customer just gets an email offering the job, they tap to book, it drops into the diary.
If a customer doesn't respond to a reminder, an automatic chaser goes out, and on the paid plans one SMS follow-up. After that Bookso stops - the customer stays visible in your pipeline so you can phone them yourself or leave them.
Plug the leaky round
A customer who's got their next clean already in their calendar never drops off. That's the whole game. When the reminder comes from your business name, on time, every time, the customer doesn't drift - they treat you like the gas man or the milk delivery, not a supplier they might replace.
The other quiet earner is add-on jobs. Most window cleaners never systematically offer conservatory roofs, gutter clears or fascia washes to their existing round - not because customers wouldn't buy them, but because remembering to ask 300 customers once a year is impossible. Bookso does it for you. Set each add-on as its own job type on a 12-month cycle and every customer on your round gets asked automatically, at roughly the right time of year, with a one-tap booking link. Even a small conversion rate can double revenue per customer.
Why window cleaners pick Bookso alongside Cleaner Planner / George / Squeegee
Cleaner Planner, George Systems and Squeegee are proper round-management tools built by round-management people. They're good at what they do: routes, days, payments, arrears reports. If you already use one, you probably don't need to move.
Bookso is different. It's customer-communication first, not round-logistics first. The strength is in what the customer sees and does: the branded email, the one-tap booking link, the chaser, the add-on offers, the confirmed booking landing back in your diary. That's the layer round software has historically been weak at.
Plenty of window cleaners use both: Cleaner Planner or George for the round and the money, Bookso for the customer-side communication and add-ons. You don't have to move anything - just add Bookso alongside and let it handle the talking-to-customers bit.
Works alongside your existing tools. Already using Cleaner Planner, George Systems, Squeegee, RoundPartner or a paper round book? Keep them. Bookso is designed to sit alongside your existing round software rather than replace it - it handles the customer-side communication and add-on rebooking so your round logistics can stay exactly as they are.
Frequently asked questions
Can customers be on different frequencies in the same round?
Yes. 4-weekly, 6-weekly, 8-weekly, monthly and one-off customers can all live in the same account. Each customer has their own interval, and the dashboard shows you who's due this week regardless of frequency. When you mark a visit done, the next one is scheduled automatically from that date - so weather slippage doesn't pile the whole round up in one week.
How do gutter, conservatory and fascia add-ons work?
Add each add-on as its own job type with its own price and interval - typically 12 months for gutters, 12 months for conservatory roofs, 6 or 12 months for fascia and UPVC. Every customer on your round automatically becomes a candidate for whichever add-ons you've set up, and Bookso emails them a one-tap booking offer at roughly the right time of year. Any bookings drop straight into your diary.
Does Bookso replace my round software?
Not necessarily. If you're already happy with Cleaner Planner, George or Squeegee for the day-to-day round, keep them. Bookso is designed to sit alongside them and handle the customer-communication layer they're weakest at: branded reminders, one-tap rebooking, add-on offers and confirmed bookings landing back in your diary. Some window cleaners run Bookso as their only tool; others run it alongside their existing round software.
What happens if a customer ignores the reminder?
Bookso sends one automatic email chaser after a few days, and on the Pro or Business plan one SMS follow-up if they still haven't booked. After that Bookso stops - the customer stays visible in your pipeline so you can phone them, skip them, or leave them. Bookso will never keep spamming a customer who's clearly not engaging.
How much does it cost for a window cleaner?
Your first 5 customers are free forever, no card required. Pro is £14.99/month (or £149/year, which is 2 months free) for unlimited customers, email and SMS reminders, chasers and CSV import. Business is £44.99/month (£449/year) and adds team members plus more SMS credits. No setup fee, no contract, cancel any time.
Is my round data safe and GDPR compliant?
Yes. Customer data is stored in the UK/EU region, encrypted at rest and in transit, and Bookso operates under UK GDPR. Customers can unsubscribe from reminders with one tap, and you can export or delete any customer's data on request from your dashboard. Bookso only uses your round to send the reminders you configured - we never market to your customers ourselves.
