AI Sales Proposal Workflow: n8n Form → OpenAI → PandaDoc

Turn sales-call notes into a PandaDoc proposal—automatically

This AI Sales Proposal Workflow captures your client details in an n8n form, uses OpenAI to generate structured proposal content, creates a tailored PandaDoc document from your template (including pricing), and then emails the client a link to the presentation plus an invoice note via Gmail.

What this workflow does

• Collects sales-call details using the n8n “Sales Call Logging Form” submission (client and project information).
• Generates proposal copy with OpenAI by sending the form inputs to OpenAI and receiving a JSON object that includes proposal titles, problem/solution text, scope items, and timeline milestones.
• Creates a PandaDoc document from a template by filling your PandaDoc template tokens with the OpenAI-generated fields—covering client/company data, scope, timelines, and pricing.
• Sends client communications with Gmail using the client’s email address, including a note that an invoice has also been sent and a link to the Google Slides presentation.

Use cases

• When your team logs a new opportunity after a call, automatically draft and generate a proposal package without manual copy/paste.
• SaaS operators who want faster turnaround: convert call notes into a PandaDoc proposal with consistent structure and pricing.
• Automation engineers standardizing sales deliverables: keep scope and timeline sections aligned to a template while using OpenAI for wording.

Technical details

• n8n Form Trigger receives submissions from the “Sales Call Logging Form.”
• OpenAI node generates structured JSON proposal content.
• PandaDoc API creates a new document from a specified PandaDoc template and populates tokens (update the template UUID and token names to match your template).
• Gmail node emails the client with the Google Slides link and an invoice note.
• Includes related nodes such as HTTP Request and nodes listed in the workflow’s tech stack (e.g., sticky note, and n8n-nodes-langchain-openai).

Setup basics: add OpenAI credentials and choose a model, configure PandaDoc API access, and set up Gmail OAuth credentials and sender details before publishing your n8n form.
