Each screen does what makes sense where you are. Everything syncs, and nothing is lost when the signal drops.
Estimate: about 30 min per quote in the evening, versus 10 min on site. One evening counts as 2 hours. This figure has not yet been measured with our testers.
Try it on my real quotesMost disputes with a client start with “that wasn't in the plan”. KYNA keeps a record of every step.
What you'll do, how long it takes and at what price: written in the quote the client accepts.
The client wants more? A numbered, priced change order, accepted by link or signed on screen before you start.
Deposit invoice in one click, automatically deducted from the final invoice.
No foreign template to adapt. Calculations are exact to the cent, never done by AI.
Several rates on one quote, with a total per rate.
The official “home over ten years old” wording printed on the invoice.
Building work for a VAT-registered business: legal wording and zero VAT.
Structured payment reference and a transfer QR code that banking apps can read.
Numbering with no gaps; an issued invoice can't be changed, you correct it with a credit note.
VAT numbers and IBANs checked as you type.
