The reality
Paperwork is not your trade
Yet it decides your evenings - and often your margins.
One missed lineand the margin vanishes
An unbilled call-out or forgotten material: it looks fine on paper, not on your bank balance.
A late quoteand a competitor wins
A fuzzy document sent three days after the visit often means the job goes elsewhere.
What if the quote happened while you are still with the client?
How it works
A professional quote in 3 steps
From mic to sent PDF - no spreadsheet, no sacrificed evening.
Step 1: You speak
Describe the job out loud, like you would to a client: work, quantities, call-out. Ninety seconds is enough, even with noise around you.
Step 2: AI structures - with your prices
Lines, quantities and labels are extracted automatically and priced from your personal catalogue. No invented rates, no forgotten lines.
Step 3: You review, you send
PDF with your logo, legal mentions automatic, email in one click. Quote accepted? It becomes an invoice - deposit, balance or credit note included.
