Flat roofs, balconies or a problem leak — price by the square metre, spell out the guarantee, and invoice the day it’s sealed.
The waterproofing specialist who sends a proper quote first looks the most professional — and gets the work.
A verbal price for a job nobody can see the value of, and a customer who queries the bill because the guarantee was never written down.
A clear quote by the square metre that spells out the system and the guarantee, so the price makes sense and the invoice isn’t questioned.
Standing on the job? Build a branded, VAT-sorted quote and send it as a clean PDF before you’ve packed your tools.
A professional quote in their hand right now beats “I’ll email you next week.” Looking legit is how you win the work.
Job done — tap once to turn the quote into a tax invoice, log the payment, and watch what you’re owed in real time.
