Window cleaning invoices for rounds, one-offs, and gutter work.

SayInvoice helps window cleaners turn fresh job notes into professional quote and invoice PDFs, with the customer details, job description, totals, VAT and payment terms kept together.

  • Your logo and business details perfectly formatted.
  • Bank details and payment terms automatically attached.
  • Pre-written messages for WhatsApp or email.

Made for window cleaners who would rather be on the tools than doing admin.

After a job, say the customer name, what you did, materials, price, VAT and payment terms. SayInvoice turns it into a draft quote or invoice you can check and send as a PDF.

1

Talk to your phone

Hit the big mic button. Tell it the client's name, what you did, and the price.

2

Check the draft

The app types it out, does the maths, and adds VAT if you need it. You approve before anything is sent.

3

Send & get paid

Send a proper PDF by WhatsApp or email before the admin follows you home.

Straight answers.

No tech jargon, just how it works for your business.

Can I handle recurring customers?

Yes. Save customer details and create new invoices quickly after each visit.

Can I include gutter clearing?

Yes. Add gutter clearing as a separate line when it is outside the normal round.

Can I use this for quotes as well as invoices?

Yes. SayInvoice supports quotes and invoices, so you can quote first and turn accepted work into a final invoice later.

Does SayInvoice send anything before I check it?

No. The app creates a draft first, so you can check the customer, work details, totals, VAT, and payment terms before sending.
