How to organise a window cleaning round

1. Start with one reliable customer list

To organise a window cleaning round, keep each customer's service, frequency, next due date and unpaid balance in one place. Group due work by area, allow time for travel and access, then record the completed visit separately from payment. You can use this method in a book, a spreadsheet or round software.

Start by making one row or record per customer. If you have records in two phones, an old book and a spreadsheet, reconcile them before planning the next week. Keep the original copies until you have checked the new list.

• Who and where: customer name, address, postcode and the contact details you need.
• What you do: service, agreed price and practical notes such as access, parking or a conservatory.
• When you return: frequency, last completed visit and next due date.
• What happened: whether the visit was completed, moved or skipped, and any reason you need to remember.
• What is owed: opening unpaid balance, charges for completed work and payments received.

Keep notes useful and factual. A short note that the gate must be unlocked is easier to act on than a long account of every conversation. Check the customer's number before sending any message.

2. Group the work by area, then by due date

Give each area a name you recognise: a village, an estate or a group of nearby streets. Within that group, check which customers are due in the coming week. The goal is to spend more of the day cleaning and less of it crossing the same town repeatedly.

Keep the service interval attached to each customer. Four-week, six-week and eight-week customers will fall together on some visits and apart on others. Do not change everyone's frequency just to make a tidy calendar. If you agree a new interval or price, update the customer record and confirm the change.

Before making the list final, check access windows and any customer arrangements. A house that can only be reached at a particular time may determine the order more than its position on the map.

3. Plan a day you can actually finish

Estimate the cleaning time from your own previous visits, then add travel, parking, setting up and packing away. Allow for a break and some spare time. A route that looks short on a map can still be too full when several houses take longer than expected.

Planned minutes = cleans × average minutes per clean + total travel, parking and setup + breaks + delay allowance. Subtract the planned minutes from your available day to see the time remaining.

This example is a planning illustration, not a target for how quickly to work. Replace every estimate with timings that fit your services, equipment and customers. If the total does not fit your available day, move some work before promising arrival times.

4. Give moved and skipped visits a clear result

When weather or access interrupts the day, start with the affected visits. Decide which will move, which the customer has asked to skip and which were already completed. Do not mark unfinished work as done just to clear the list.

For a moved visit, write down the new working date and review what happens to the following due date. You may keep the original cycle or restart it from the actual clean; choose deliberately and agree any material change with the customer. A delay should not silently turn a four-week service into a different arrangement.

Check the space in the receiving day before carrying the work forward. If Tuesday is already full, moving all of Monday into it only hides the problem. Use your area groups to find a realistic catch-up slot, then tell affected customers what to expect.

5. Keep the visit record separate from the money

At the end of a clean, record the completed work and the agreed charge. If the customer pays later, leave that amount outstanding until you have received and checked it. Marking a customer as paid because they said they would transfer the money makes the balance unreliable.

For example, a fictional customer who owes £20 and receives another £20 clean has a £40 balance. A subsequent £20 payment brings it back to £20; it does not erase the newest visit. A clear sequence of charges and receipts is easier to check than overwriting a single note.

Set aside a regular time to match payments and review unpaid balances. Check the figures before sending a polite reminder, especially if a transfer may have arrived under another person's name. Keep using your normal invoicing and accounting process where needed.

6. Close the week and keep a copy

Before planning the next week, look for uncompleted visits, overdue customers, notes that need a reply and payments waiting to be matched. Compare your planned timings with the days you actually worked. Adjust the estimates for difficult access, bigger properties or slow travel rather than repeatedly overfilling the diary.

Keep a dated backup or export of your records in a place you can recover. If you switch systems, check a sample of names, addresses, prices, frequencies and opening balances against your original list. Check the full totals too; a few correct examples do not prove the whole move is complete.

When round software becomes useful

A book or spreadsheet may work while the round is small and the records stay clear. Software becomes useful when finding due work, handling changes and checking balances takes too much time or causes repeated mistakes. Test those tasks with realistic examples before switching.

Knockround's window cleaning workflow brings the day's list, customer notes, map and balances together in a browser. It is in early access; the public demo uses fictional customers and sends nothing to anyone. WhatsApp messages are prepared for you to review and send from your own number, rather than delivered automatically.
