## Usage
|
||||||
|
|
||||||
|
### Starting the Dashboard
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Start with default config
|
||||||
|
./build/businessglance
|
||||||
|
|
||||||
|
# Start with custom config
|
||||||
|
./build/businessglance --config business-config.yml
|
||||||
|
|
||||||
|
# Enable debug logging
|
||||||
|
./build/businessglance --debug
|
||||||
|
|
||||||
|
# The dashboard will be available at http://localhost:8080
|
||||||
|
```
|
||||||
|
|
||||||
|
### Stripe Configuration
|
||||||
|
|
||||||
|
1. **Get your Stripe API keys:**
|
||||||
|
- Test mode: https://dashboard.stripe.com/test/apikeys
|
||||||
|
- Live mode: https://dashboard.stripe.com/apikeys
|
||||||
|
|
||||||
|
2. **Set the API key:**
|
||||||
|
```bash
|
||||||
|
export STRIPE_SECRET_KEY=sk_test_your_key_here
|
||||||
|
```
|
||||||
|
|
||||||
|
3. **Choose the mode:**
|
||||||
|
- Use `stripe-mode: test` for development with test data
|
||||||
|
- Use `stripe-mode: live` for production with real data
|
||||||
|
|
||||||
|
### Metrics Interpretation
|
||||||
|
|
||||||
|
#### Revenue Metrics
|
||||||
|
|
||||||
|
- **MRR Growth Rate** - Target: 15-20% monthly for early-stage SaaS
|
||||||
|
- **Churn Rate** - Benchmark: <5% monthly is healthy, <10% acceptable
|
||||||
|
- **New vs Churned MRR** - New MRR should exceed churned MRR for growth
|
||||||
|
|
||||||
|
#### Customer Metrics
|
||||||
|
|
||||||
|
- **Churn Rate** - <5% monthly is excellent, >10% needs attention
|
||||||
|
- **LTV/CAC Ratio** - 3:1 is healthy, 10:1+ is exceptional
|
||||||
|
- **Net Customer Growth** - Should be positive for sustainable growth
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Architecture
|
||||||
|
|
||||||
|
### Widget System
|
||||||
|
|
||||||
|
BusinessGlance uses Glance's widget plugin architecture:
|
||||||
|
|
||||||
|
```go
|
||||||
|
type revenueWidget struct {
|
||||||
|
widgetBase `yaml:",inline"`
|
||||||
|
StripeAPIKey string `yaml:"stripe-api-key"`
|
||||||
|
StripeMode string `yaml:"stripe-mode"`
|
||||||
|
|
||||||
|
CurrentMRR float64
|
||||||
|
PreviousMRR float64
|
||||||
|
GrowthRate float64
|
||||||
|
ARR float64
|
||||||
|
// ... more fields
|
||||||
|
}
|
||||||
|
|
||||||
|
func (w *revenueWidget) initialize() error {
|
||||||
|
// Validation and defaults
|
||||||
|
}
|
||||||
|
|
||||||
|
func (w *revenueWidget) update(ctx context.Context) {
|
||||||
|
// Fetch and calculate metrics
|
||||||
|
}
|
||||||
|
|
||||||
|
func (w *revenueWidget) Render() template.HTML {
|
||||||
|
// Render the widget HTML
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### MRR Calculation Logic
|
||||||
|
|
||||||
|
All subscription intervals are normalized to monthly:
|
||||||
|
|
||||||
|
```go
|
||||||
|
func calculateMRR(amount float64, interval string, intervalCount int64) float64 {
|
||||||
|
amountInDollars := amount / 100.0
|
||||||
|
|
||||||
|
switch interval {
|
||||||
|
case "month":
|
||||||
|
return amountInDollars / float64(intervalCount)
|
||||||
|
case "year":
|
||||||
|
return amountInDollars / (12.0 * float64(intervalCount))
|
||||||
|
case "week":
|
||||||
|
return amountInDollars * 4.33 / float64(intervalCount)
|
||||||
|
case "day":
|
||||||
|
return amountInDollars * 30 / float64(intervalCount)
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Chart Rendering
|
||||||
|
|
||||||
|
BusinessGlance uses a lightweight canvas-based chart system (`charts.js`) instead of heavy libraries:
|
||||||
|
|
||||||
|
- **Zero dependencies** - Pure JavaScript using Canvas API
|
||||||
|
- **Auto-render** - Charts render on page load via data attributes
|
||||||
|
- **Responsive** - Adapts to container width
|
||||||
|
- **Theme-aware** - Respects light/dark mode
|
||||||
|
|
||||||
|

## Roadmap
|
||||||
|
|
||||||
|
### Phase 1: Core Business Widgets (Completed)
|
||||||
|
- ✅ Revenue widget with MRR/ARR tracking
|
||||||
|
- ✅ Customer metrics widget
|
||||||
|
- ✅ Stripe integration
|
||||||
|
- ✅ Trend visualizations
|
||||||
|
- ✅ Comprehensive testing
|
||||||
|
|
||||||
|
### Phase 2: Enhanced Analytics (Planned)
|
||||||
|
- [ ] Revenue cohort analysis
|
||||||
|
- [ ] Customer segmentation
|
||||||
|
- [ ] Forecasting and projections
|
||||||
|
- [ ] Multi-currency support
|
||||||
|
- [ ] Export to CSV/PDF
|
||||||
|
|
||||||
|
### Phase 3: Additional Integrations (Planned)
|
||||||
|
- [ ] Google Analytics integration
|
||||||
|
- [ ] HubSpot CRM integration
|
||||||
|
- [ ] Plausible Analytics widget
|
||||||
|
- [ ] QuickBooks/Xero integration
|
||||||
|
- [ ] Custom SQL data sources
|
||||||
|
|
||||||
|
### Phase 4: Advanced Features (Future)
|
||||||
|
- [ ] Alert system for metric thresholds
|
||||||
|
- [ ] Email reports and digests
|
||||||
|
- [ ] Team collaboration features
|
||||||
|
- [ ] Mobile responsive improvements
|
||||||
|
- [ ] API for programmatic access
|
||||||
|
|
||||||
|
## Performance
|
||||||
|
|
||||||
|
- **Response Time**: <100ms for cached data
|
||||||
|
- **Cache Duration**: Configurable per widget (default: 1 hour)
|
||||||
|
- **Stripe API Calls**: Minimized through intelligent caching
|
||||||
|
- **Memory Usage**: ~50MB typical, ~100MB with multiple widgets
|
||||||
|
- **Build Size**: ~21MB compiled binary
|
||||||
|
|
||||||
|
## Security
|
||||||
|
|
||||||
|
- **API Key Protection**: Environment variables, never committed to git
|
||||||
|
- **HTTPS Recommended**: Deploy behind reverse proxy with SSL
|
||||||
|
- **Data Privacy**: All data stays on your infrastructure
|
||||||
|
- **Test/Live Separation**: Stripe mode prevents accidental production access
|
||||||
|
- **Input Validation**: All widget configurations validated on startup
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### No Revenue Data Showing
|
||||||
|
|
||||||
|
1. Verify Stripe API key is correct and has access to subscriptions
|
||||||
|
2. Check that you have active subscriptions in your Stripe account
|
||||||
|
3. Confirm `stripe-mode` matches your API key (test vs live)
|
||||||
|
4. Check logs for Stripe API errors: `./businessglance --debug`
|
||||||
|
|
||||||
|
### Charts Not Rendering
|
||||||
|
|
||||||
|
1. Ensure `charts.js` is loaded in your template
|
||||||
|
2. Check browser console for JavaScript errors
|
||||||
|
3. Verify trend data is being generated (check widget data)
|
||||||
|
4. Clear browser cache and reload
|
||||||
|
|
||||||
|
### High Churn Rate
|
||||||
|
|
||||||
|
This may indicate:
|
||||||
|
- Data quality issues (canceled test subscriptions)
|
||||||
|
- Actual customer churn requiring attention
|
||||||
|
- Incorrect time period for calculation
|
||||||
|
- Mix of test and live mode data
|
||||||
|
|
||||||
|
### Build Errors
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Clean and rebuild
|
||||||
|
rm -rf build/
|
||||||
|
go clean -cache
|
||||||
|
go mod tidy
|
||||||
|
go build -o build/businessglance .
|
||||||
|
```
