Problem

Micro-agencies spend 2–4 hours preparing a single commercial proposal: manually gathering client data, searching for relevant case studies, calculating costs in Excel, and formatting the document. Templates aren't personalized, history gets lost, and there are no CRM integrations.

Solution

The application automates the entire cycle: a form with validation collects client data and saves it to SQLite, the LLM core generates text from templates with variable substitution, the calculator computes cost and timelines using formulas, and the export module produces a branded PDF. History is stored in the database, with search and re-export available. Webhooks and CSV import make it possible to connect a CRM and automate launches via n8n/Make.

More details

AI Commercial Proposal Generator is a deployment-ready web application that turns client data input into a structured commercial proposal in minutes. You fill out a form: niche, pain points, budget, timelines, contacts — the system inserts them into proven templates, calls an LLM (OpenAI, Anthropic, or a local model), and generates a ready document with an introduction, pain point analysis, solution, case studies, cost calculation, and timelines. The application solves the main problem of micro-agencies: manually drafting proposals takes hours, and Google Docs templates don't account for client specifics. Here you get personalization at the level of meaning — the LLM adapts the text to the niche and pain points, while the calculator automatically computes cost using formulas with complexity coefficients, discounts, and taxes. All client data is stored in SQLite, and the generation history is available for search and re-export. Included is a library of templates for marketing, development, and consulting with customization rules for budget and pain points. PDF export is customizable to your brand: logo, colors, fonts. The web interface on React + FastAPI (or Express) includes input pages, proposal viewing/editing, and history. Deployment via Docker or Vercel — with instructions on environment variables and basic authentication. For integrations, webhooks, CSV import, and ready-made examples for connecting to HubSpot and Bitrix24 are provided, along with sending notifications to Telegram and automation via n8n/Make. All documentation consists of 8 detailed .md files with code, diagrams, and examples. This is not a prompt pack, but a working system that you can launch today and use in your agency's daily work.
