Answer Capsule

DocuQueue is an API-first proposal generation tool. Upload a .docx template, connect your CRM data source, and generate sales proposals, SOWs, and quotes in under 10 seconds. MCP integration lets Claude, GPT, or any AI agent generate proposals directly. No proposal software required.

What is Proposal Generation API?

A proposal generation API creates PDFs from templates and CRM data programmatically. Instead of manually building proposals in Word or Google Docs, you send a POST request with client details, pricing, and scope — and receive a branded PDF in seconds.

Think of it as mail merge, but via API. Your backend, CRM, or AI agent triggers proposal generation. No UI required, no manual steps, no copy-paste errors.

The result? Your reps stop spending 30-45 minutes per proposal and start generating them programmatically in under 10 seconds.

Start Saving Time

When to Automate vs. When to Stay Manual

Not every document needs automation. Here's a simple framework:

Automate if...
  • ✓ You send the same document 10+ times/month
  • ✓ The document uses data from your CRM
  • ✓ Errors cost you deals or create legal risk
  • ✓ Your reps spend 30+ min per proposal
Keep manual if...
  • × You send it less than 5 times/month
  • × Every instance is truly unique
  • × The document requires heavy creative writing
  • × You're a solo operator with simple needs

How It Works — API vs. Manual

Here's what changes when you switch from manual proposal drafting to DocuQueue's API:

The Old Way (Word / Manual)
  • × Open old proposal, "Save As" new file
  • × Find client data in CRM, copy-paste
  • × Manually update pricing, line items, scope
  • × Hope you didn't miss a field
  • × Export to PDF, email manually
Time: 30-45 minutes
The DocuQueue Way (API)
  • POST deal data to DocuQueue API
  • API pulls client data automatically
  • Template fills with correct pricing, scope
  • Conditional logic handles edge cases
  • PDF generates, ready to send or sign
Time: Under 10 seconds
Build Your First Template Setup takes under 5 minutes
