Hey Product Hunt! I'm Sal, the founder of Larzo.
I built this because I kept hearing the same thing from tradespeople — electricians, plumbers, builders — they hate doing paperwork in the evenings. Most are still using Word templates or handwriting quotes, then chasing payments with no real system.
Larzo fixes the whole loop: describe the job, AI writes up a professional description of works, you add your prices, and it generates a PDF quote you can send on WhatsApp in under 2 minutes. When the customer accepts, convert it to an invoice with one tap. Track payments, snap receipts for expenses, and your accountant gets an automatic monthly financial report with everything they need.
It's a PWA so it works straight from the phone — no app store needed. We're live with real users in the UK and just launched Making Tax Digital compliance (the new HMRC requirement hitting 780,000 sole traders this year).
Would love your feedback — especially if you work with tradespeople or know someone who does. Happy to answer any questions!
