How the team uses this app

Set your accurate prices once in Price Book.
Open New Quotation, describe the customer or use the auto-suggestion panel (bill or appliances) — or ask Groq AI.
Check the totals, save, then Print / PDF or copy the WhatsApp summary.
When the customer confirms, convert the quotation to an Invoice and track payments.

Groq AI Assistant Free tier
