Instant Price Quote n8n Form: Data Tables + Gmail + Telegram

Instant Price Quote in n8n—turn your Data Tables into a 2-page customer estimator

Give leads a real number in seconds. This Instant Price Quote n8n Form uses your Data Tables price list to build a two-page quote form, emails the estimate via Gmail, saves it to price_estimates, and alerts you on Telegram—so you stop waiting for replies.

What this workflow does

• Collects contact details on page 1 (name, email, phone).
• Loads active services dynamically from your price_list Data Table, then generates page 2 so the dropdown always reflects current services.
• Lets the customer select service, quantity, optional express option, and notes.
• Calculates the estimate using: unit price × quantity, two volume discount tiers, express surcharge, per-service minimum charge, then applies VAT.
• Generates an estimate ID (e.g., EST-20261018-4821) and saves the full quote into the price_estimates Data Table.
• Notifies you on Telegram and sends the quote to the customer via Gmail, with the breakdown shown on the last form page.

Use cases

• Service businesses that publish pricing (installation, maintenance, creative services) and want instant lead quotes.
• n8n builders who want a repeatable Data Tables + form pattern for dynamic quoting.
• SaaS operators collecting estimates and tracking quote submissions automatically.
