- Payment intervals (weekly, monthly, etc.)
|
||||
- Description matching (fuzzy logic)
|
||||
- Category grouping
|
||||
- **Confidence scoring** (0-100%) for each detection
|
||||
- **Minimum 3 occurrences** required for pattern
|
||||
- **Auto-suggests subscriptions** based on detected patterns
|
||||
|
||||
### 2. **Subscription Management** 💳

## 🧠 Detection Algorithm
|
||||
|
||||
### Pattern Matching Logic
|
||||
```python
|
||||
1. Fetch all expenses from last year
|
||||
2. Group by similarity:
|
||||
- Same category
|
||||
- Amount within 5% or $5
|
||||
- Description match (60% overlap)
|
||||
3. Analyze intervals between transactions:
|
||||
- Calculate average interval
|
||||
- Check consistency (variance)
|
||||
- Map to frequency (weekly, monthly, etc.)
|
||||
4. Generate confidence score:
|
||||
- Base: 50-70% (interval consistency)
|
||||
- +15% for monthly patterns
|
||||
- +10% for low amount variance (<5%)
|
||||
- -10% for high variance (>20%)
|
||||
5. Create suggestion if confidence >= 70%
|
||||
```
|
||||
|
||||
### Supported Frequencies
|
||||
- **Weekly** (7 days ± 2)
|
||||
- **Bi-weekly** (14 days ± 2)
|
||||
- **Monthly** (30 days ± 3)
|
||||
- **Quarterly** (90 days ± 5)
|
||||
- **Yearly** (365 days ± 10)

|

## 🐛 Troubleshooting
|
||||
|
||||
### No patterns detected?
|
||||
- Need minimum 3 similar transactions
|
||||
- Check amounts are within 5% similarity
|
||||
- Ensure consistent payment intervals
|
||||
- Verify same category used
|
||||
|
||||
### Low confidence scores?
|
||||
- Irregular payment dates reduce confidence
|
||||
- Varying amounts affect scoring
|
||||
- Try manual entry for irregular subscriptions
|
||||
|
||||
### Subscriptions not showing on dashboard?
|
||||
- Verify `next_due_date` is set
|
||||
- Check subscription `is_active` = True
|
||||
- Ensure date within 30 days
|
||||
