If you work a regular round in the UK and collect by direct debit, the best window cleaning software is a round-based app built for window cleaners. If you quote one-off and recurring jobs with a crew, a field service platform with a window cleaning set-up fits better, and how many people you'll add over the next year decides which pricing model ends up cheapest.
Which one is yours? Picture next Tuesday. Is it 40 houses on the same four streets you did four weeks ago, with most customers paying by mandate before you've even knocked? Or is it two shopfronts, a quote for a conservatory roof and a post-construction clean, with a lad on the second van? The first is a round. The second is a field service business that happens to clean glass. Software built for one handles the other badly, and that's the whole decision in a sentence.
Try this on twenty real customers before you choose
Every trial looks tidy with demo data. Yours won't be. Pick your two front runners and give each one an hour with this test, using your own customers, not made-up ones.
- Import 20 real customers from your book or spreadsheet, including one with a gate code, one who wants frames and sills done every other visit, and one commercial account billed monthly.
- Set each on its real frequency (four-weekly, eight-weekly, monthly) and see whether the next six months of visits appear without you typing them in.
- Mark one house as rained off and move the whole day. Count the taps. Rain is the test most demos skip, and it's the one you'll run every few weeks.
- Mark three jobs done and send the invoices or payment requests from your phone, standing up, one-handed.
- Take a payment the way your customers pay now: a direct debit mandate, a card on the doorstep, or a bank transfer. If the tool can't do your main method, stop there.
- Export the customer list back out to a spreadsheet. If you can't find the export now, you won't find it when you want to leave.
Whichever tool gets through all six without a workaround is your pick. If neither does, the one that failed on rain or payments is out first; you'll live with a clunky export, but you won't live with chasing money.
Rounds or jobs: the fork that decides it
The tools window cleaners shortlist fall into two camps, and they think about work differently.
Round apps treat your customers as a repeating route. The round is the unit: you work it, mark what's done, and the money follows, often by direct debit. They're built for owner-operators and small crews doing residential work on a cycle, and the UK round app on this list puts unlimited rounds and jobs on every plan, with direct debit and card payments built in.
Field service platforms treat each visit as a job with a quote, a schedule slot, a technician and an invoice. Most of the big US platforms here publish a dedicated window cleaning page and offer a free trial, but underneath, the core product is general field service software sold across many trades. That's a strength if you also do gutters, pressure washing or commercial contracts with formal quotes, because the job record holds all of it. It's a weakness if 90% of your week is the same houses on a cycle, because you'll spend your evenings fighting a scheduler built for one-off call-outs.
There's a third, smaller group: general booking and service platforms that list window cleaning among a dozen trades. They suit businesses that take a lot of new bookings online and want the booking page to be the front door. If your work comes mainly from repeat customers, you won't use half of what you'd be paying for. If you're comparing across trades, our guide to cleaning business scheduling software covers that wider field.

How the monthly bill grows as you add a van
Read the vendors' own pricing pages this week and you'll see two currencies, so treat them as two ranges. The UK round app starts at £19 a month for a single user. In US dollars, the cheapest entry plans start just under $30 a month, and the dearest entry plan here is $208 a month, billed yearly, with unlimited users. Several of the dollar figures are monthly prices that only apply if you pay for the year up front, so check the monthly price before you compare. One of the eight shows no figure on its pricing page, so you'll need a call to price it.
What moves the bill is people. You'll meet three patterns. Some tools charge a flat fee with unlimited users, which costs more on day one and nothing extra when you hire. Some include a set number of users in each tier, so the price jumps when you cross the line, for example from one user to five. And some charge a base fee plus a monthly amount for every extra user or employee. For a solo cleaner the per-user model is usually cheapest. For a business with three vans and a part-timer on Saturdays, work it out both ways, because the flat plan can overtake it.

I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
Then add the extras that sit outside the plan: text message bundles for reminders, card processing fees on every payment, and the direct debit provider's charge per collection if your tool connects to one. On a round of small, frequent payments, those per-transaction fees can matter more than the subscription.
If you're already on a per-user platform and the charge for each extra person is what's hurting, our guide to Jobber alternatives walks through the flat and tiered routes.
Where window cleaners go wrong
Buying the biggest name for a one-van round. A full field service suite will do everything, and you'll pay for dispatch boards and job costing you never open. If you work alone on a cycle, start with a round app.
Choosing before checking payments. The fastest way to hate new software is to find it can't collect money the way your customers already pay. Test your main payment method on day one of the trial.
Moving in the busy season. Switch in a quiet month, run the old book alongside for one full cycle, and only cancel the old system once every customer has been visited and paid through the new one.
Forgetting the UK question. Plenty of field service software is written for US trades. If you're UK-based, check direct debit, VAT on invoices and pounds before anything else; our list of field service management software for the UK is a useful second shortlist.
Do you make window cleaning or field service software? Tool makers can ask to be considered for a featured place on this list.
Before you move your round across
Clean your customer list before you import it: merge duplicates, add the frequency and price you charge each customer, and note who pays how. A tidy spreadsheet imports in minutes; a messy one turns the first week into data entry.
Then tell your customers before the first new-style reminder or payment request lands. A one-line text saying you're moving to a new booking system, and that the next message will come from it, stops people ignoring a link they don't recognise. If you're moving to direct debit for the first time, give them a reason that helps them, such as never having to remember to pay, rather than one that only helps you.
Last, keep the old export somewhere safe for at least a year. You won't need it often, but the day a customer disputes a payment from last spring, you'll be glad it's there.
Which kind of tool I'd pick for your business
Working a round on your own, mostly residential, paid by direct debit: a round app built for window cleaners. You'll pay the least, and the tool thinks the way your week runs.
Two to five people, or a lot of quoted work such as commercial contracts and one-off cleans: a field service platform. Pick one that includes several users in its tier or charges a flat fee, and price it at your size today and with one more van.
Most new work arrives through an online booking form: a booking-led service platform, so the booking page does the selling and the scheduling follows from it.
UK-based with a crew and commercial accounts: start with the round app's team tier, and only move to a field service suite if quoting and job records start to outgrow it. Whichever way you lean, run the 20-customer test before you move a single customer across.
