How to Build a Document Version Control System for Sales

This document version control system for sales proposals ensures reps always use the latest templates. No more sending outdated pricing or old case studies.

What You Need Before Starting

• Python 3.8+
• Claude or GPT API key
• Jinja2 for templating
• weasyprint for PDF generation

Step 1: Define Your Data Model

Set up the structure for version control records.

import json
import sqlite3
from datetime import datetime

def init_db():
    conn = sqlite3.connect("version_control.db")
    conn.execute("""CREATE TABLE IF NOT EXISTS version_control (
        id INTEGER PRIMARY KEY AUTOINCREMENT,
        deal_id TEXT, content TEXT, status TEXT DEFAULT 'draft',
        created_at TEXT, updated_at TEXT
    )""")
    conn.commit()
    return conn

Step 2: Pull CRM Context

Get deal and company data to populate your version control.

def get_context(crm_client, deal_id):
    deal = crm_client.get_deal(deal_id)
    company = crm_client.get_company(deal["company_id"])
    return {
        "deal_name": deal["name"],
        "company": company["name"],
        "industry": company["industry"],
        "amount": deal["amount"],
        "notes": deal.get("notes", ""),
    }

Step 3: Generate Content with AI

Use Claude to create customized version control content.

import anthropic

def generate_content(context):
    client = anthropic.Anthropic()
    message = client.messages.create(
        model="claude-sonnet-4-20250514", max_tokens=2000,
        messages=[{"role": "user",
            "content": f"Generate version control content for {context['company']} in {context['industry']}.\nDeal value: ${context['amount']:,.0f}\nNotes: {context['notes']}"}]
    )
    return message.content[0].text

Step 4: Format and Export

Create a professional output document.

def export_document(content, context, output_dir):
    filename = f"{context['deal_name']}_{datetime.now().strftime('%Y%m%d')}.md"
    path = os.path.join(output_dir, filename)
    with open(path, "w") as f:
        f.write(f"# {context['company']}\n\n{content}")
    return path

Step 5: Track and Measure

Log every document and track conversion.

def log_document(conn, deal_id, path, status="draft"):
    conn.execute(
        "INSERT INTO version_control (deal_id, content, status, created_at, updated_at) VALUES (?, ?, ?, ?, ?)",
        (deal_id, path, status, datetime.now().isoformat(), datetime.now().isoformat()))
    conn.commit()

What to Build Next

Add notifications when templates update so reps always know about changes.
