Why It Matters

Sales teams lose hours every week copy-pasting CRM data into proposal templates — time that should be spent closing deals. An AI proposal generator closes the loop between your CRM and your documents, ensuring every proposal is accurate, on-brand, and delivered fast.

Platform Capabilities

Everything you need to build, deploy, and manage a production-grade AI proposal agent — without touching infrastructure.

CRM-Aware Context Retrieval

The agent reads deal name, contact details, company size, deal value, and pipeline stage directly from HubSpot to inform every section of the proposal.

Dynamic Document Generation

Architect populates a branded Google Docs template with CRM data fields, AI-written sections, and pricing tables — producing a fully formatted, shareable document automatically.

Event-Driven Triggers

Configure the agent to fire on HubSpot deal stage changes, Slack slash commands, webhook calls, or scheduled batch runs — all without writing a single line of code.

Automated Delivery & Notification

Once the proposal is generated, the agent shares the Google Doc link with the assigned rep via Slack or email, and logs the document URL back to the HubSpot deal record.

Guardrails & Safety Controls

Set pricing floors, content policies, and approval gates so the agent only sends proposals within defined parameters — keeping your revenue team in control at all times.

Observability & Audit Logs

Every agent run is logged with inputs, outputs, and timestamps. Track which proposals were generated, when, and what CRM data was used — full audit trail included.

How It Works

1
Configure the Trigger
Select the HubSpot deal stage, Slack command, or webhook that fires the agent. Takes under two minutes.
2
Connect HubSpot
Authorize the HubSpot integration. The agent reads deal, contact, and company properties automatically.
3
Set Your Template
Upload or link your branded Google Docs proposal template. Define which fields map to which CRM properties.
4
Deploy & Deliver
The agent generates the Google Doc, shares it with the rep via Slack or email, and logs the link in HubSpot.

Before & After Architect

Without Architect
  • Reps spend 2-3 hours manually drafting each proposal from scratch
  • Pricing errors from manual copy-paste cause costly re-negotiations
  • No consistent format — every rep produces a different-looking document
  • Deal context from HubSpot is never fully reflected in the final document
  • Proposal sent days after the meeting — momentum is lost
With Architect
  • Complete, branded proposal generated automatically in under 60 seconds
  • Pricing and deal values pulled directly from HubSpot — zero copy-paste errors
  • Every proposal follows the same branded template — consistent across the entire team
  • Document link logged back to HubSpot and shared to rep via Slack instantly
  • Reps focus on closing — not formatting documents

Sample Agent System Prompt

This is a representative system prompt you would configure in Architect when building your AI proposal generator. The agent uses this context to retrieve CRM data, draft proposal sections, and format the final document.

You are an AI Proposal Generator agent for a B2B sales team.

On each run, you will receive a HubSpot deal ID. Your tasks:
1. Retrieve the deal's contact name, company, deal value, and stage from HubSpot.
2. Identify the relevant product tier and pricing from the internal pricing table.
3. Populate the branded Google Docs proposal template with the retrieved data.
4. Write a 2-paragraph executive summary personalized to the company's industry.
5. Insert the correct pricing table and proposed start date based on deal value.
6. Set sharing permissions so the assigned HubSpot owner can edit the document.
7. Post the Google Doc link to the deal owner's Slack DM with a short summary.
8. Log the document URL to the HubSpot deal's "Proposal URL" custom property.

Rules: Never fabricate pricing. Use only values from HubSpot or the pricing table.
If deal value is missing, pause and notify the owner via Slack before proceeding.

Frequently Asked Questions

How does the AI proposal generator connect HubSpot and Google Docs?
Architect's AI agent reads deal and contact data directly from HubSpot via its native integration, then uses that data to populate a branded Google Docs template — creating a complete, personalized proposal automatically.
Do I need to write code to build this agent?
No. Architect provides a no-code visual builder. You configure the agent's trigger, data sources, and document template through a guided UI in under 10 minutes.
Can the agent personalize proposals based on deal stage or company size?
Yes. The agent can reference any HubSpot deal or contact property — such as deal stage, company name, industry, or deal value — to tailor the proposal content and pricing sections dynamically.
What triggers the proposal generation?
You can configure triggers such as a HubSpot deal moving to a specific pipeline stage, a manual Slack command, a form submission, or a scheduled batch run for all qualifying deals.
Can the generated proposal be shared automatically?
Yes. After generating the Google Doc, the agent can automatically share it with the assigned sales rep via email or Slack, and log the document link back to the HubSpot deal record.
