How to Generate Commercial Proposals Automatically with n8n (Form → Research → PDF → Email)
Writing a commercial proposal eats 60 to 90 minutes per prospect: you research the company, tailor the value proposition, format the document, and send it before they go cold. With n8n you can compress that into the time it takes to fill out one short form — and the prospect gets a polished, personalized PDF in their inbox the same minute.
The problem: proposals are slow, manual, and inconsistent
Most sales teams lose deals not because the offer is wrong but because the proposal arrives two days late and reads like a template. Reps copy-paste from old documents, forget to update the client name, and skip the research step that makes a proposal feel bespoke. Speed and personalization are exactly where a workflow beats a human.
How the n8n workflow solves it
This n8n automation triggers on a form submission, enriches the lead by researching the company online, drafts a tailored proposal with an LLM, renders it as a branded PDF, and emails it to the prospect — end to end, no human touch required.
- A webhook or form node captures the prospect's name, company, and need
- An HTTP/research step pulls public company context (industry, size, site copy)
- An AI node writes a structured proposal: problem, solution, scope, pricing, next step
- A PDF node renders it into a branded, on-brand document
- An email node delivers it instantly with a personalized subject line

Step by step: building the automation
- Add a trigger — Use a Form Trigger or Webhook node to capture the prospect details. Keep the form to 4-5 fields so reps actually use it.
- Enrich the company — Call a research step (web scrape or an enrichment API) to gather context about the prospect's business so the proposal speaks their language.
- Draft with AI — Feed the lead data plus company context into an LLM node with a strict prompt that outputs sections: situation, solution, scope, investment, and call to action.
- Render the PDF — Map the AI output into an HTML template and convert it to PDF so every proposal looks designed, not generated.
- Send and log — Email the PDF to the prospect and write a row to your CRM or a sheet so you can track which proposals convert.
What you get out of it
- Proposals go out in minutes instead of hours
- Every document is researched and personalized, not copy-pasted
- Consistent branding and structure across the whole team
- Faster response = higher close rate while the lead is still warm
Frequently asked questions
Do I need coding skills to set this up?
No. n8n is visual — you connect nodes. The hardest part is the AI prompt, and the ready-made template ships with one that already works.
Which LLM should I use?
Any model with a strong writing capability works. Claude and GPT-class models both produce clean, structured proposals; pick based on cost and your existing API access.
Can it match my brand?
Yes. The PDF is generated from an HTML template, so you drop in your logo, colors, and fonts once and every proposal inherits them.
