Send instant price quotes from forms with Data Tables, Telegram and Gmail

Description

Quick overview For small service businesses: a two-page n8n form turns your Data Tables price list into an instant price estimate, emails it to the customer, saves it and alerts you on Telegram, so leads get a number in seconds instead of waiting for a reply. How it works Page 1 of an n8n form collects name, email and phone. The active services are loaded from the price_list Data Table and page 2 is built from them, so the dropdown always shows your current services. The customer chooses a service, quantity, an optional express option and notes. The estimate is calculated: unit price × quantity, two volume discount tiers, express surcharge, per-service minimum charge, then VAT. The estimate gets a number (for example EST-20261018-4821) and is saved in the price_estimates Data Table. You get a Telegram alert, the customer gets the estimate by Gmail, and the full breakdown is shown on the last form page. Setup Run the "Run once: create tables and sample prices" branch. It creates both tables and adds 4 sample services. Re-running it does not overwrite your prices. Replace the sample rows in price_list with your services, units, prices and minimum charges. In Settings, set business name, currency, VAT rate, discount tiers, express surcharge, validity days and Telegram chat ID. Add Telegram and Gmail credentials, activate the workflow and link the form from your website. Setup takes about 15 minutes. Requirements An n8n instance with Data Tables and multi-page Forms; a Telegram bot and chat ID; a Gmail account (or any email node). A Gmail credential (one click on n8n Cloud; on self-hosted n8n it needs a Google Cloud OAuth client), or replace the Gmail node with Send Email (SMTP) or Outlook. Customization Change tiers, surcharge and VAT in Settings; set active to false to hide a service. Replace Gmail with Outlook or SMTP and Telegram with Slack. Add fields such as address or preferred date on page 2, or turn accepted estimates into invoices or bookings. Additional info Volume discount tiers are global (they use the quantity of any service). For per-service tiers, add tier columns to price_list and adjust the Calculate the estimate node. The result is an estimate; the final price is confirmed by you. If the email cannot be sent, the customer still sees the estimate and is told that you will get in touch. If the form is public, link it only from your own website or add a captcha: each submission sends an email from your Gmail account. An n8n automation workflow template by Tomasz Kaczyński.
