Expected Output​

Recommended Stack Example:

## Proposed Tech Stack

### Website & CMS
- **Webflow** (£25/month)
  - Rationale: Client-friendly CMS, fast hosting, good SEO
  - Alternative: WordPress (more complex, requires maintenance)

### Analytics & Tracking
- **GA4** (Free)
- **Google Tag Manager** (Free)
- **Stape sGTM** (£50/month)
  - Rationale: Privacy-first tracking, ad blocker bypass
- **BigQuery** (£10/month estimated)
  - Rationale: Raw event data for custom analysis

### Advertising
- **Meta Ads** (Ad spend only)
- **Google Ads** (Ad spend only)
- **LinkedIn Ads** (Ad spend only, if B2B)

### CRM
- **TwentyCRM** (Self-hosted, £16/month server)
  - Rationale: Open source, customizable, cost-effective
  - Alternative: HubSpot (££ - more features, higher cost)

### Automation
- **n8n** (Self-hosted, £55/month server)
  - Rationale: Flexible workflows, no per-execution cost
  - Alternative: Zapier (££ - easier, but expensive at scale)

### Consent Management
- **Termly** (£12/month)
  - Rationale: GDPR/CCPA compliant, easy setup

## Cost Summary

**Monthly**: ~£168/month + ad spend
**Annual**: ~£2,016/year + ad spend

**Breakdown**:
- Webflow: £25/month
- Stape sGTM: £50/month
- BigQuery: £10/month (estimated)
- TwentyCRM server: £16/month
- n8n server: £55/month
- Termly: £12/month

## Implementation Timeline

**Phase 1: Foundation (Weeks 1-2)**
- Set up Webflow project
- Configure domain and hosting
- Basic GTM implementation

**Phase 2: Tracking (Weeks 3-4)**
