### Check Full Account Status
```bash
ACCOUNT_ID="your-account-id"

# Account details with balance

# Unpaid invoices
curl -s -u admin:password \
  -H "X-Killbill-ApiKey: fresh-tenant" \
  -H "X-Killbill-ApiSecret: fresh-secret" \

```

## Key Findings & Best Practices

1. **Overdue Configuration**: `initialReevaluationInterval` must be INSIDE `accountOverdueStates` element
2. **Payment Method**: Must be set as DEFAULT for overdue system to activate
3. **State Order**: Overdue states must be ordered from highest to lowest threshold
4. **External Payment**: System works with EXTERNAL_PAYMENT but needs time to process
5. **Traefik Access**: All KillBill API calls can be made via `http://billing.62.171.153.219.nip.io`
6. **File Uploads**: Catalog and overdue config uploads require docker exec due to file access requirements

## Important Notes

- Replace `CUSTOMER_ID_HERE`, `ACCOUNT_ID_HERE`, `SUBSCRIPTION_ID_HERE`, etc. with actual IDs
- All dates must be in ISO 8601 format with UTC timezone (e.g., `2027-03-25T03:00:00.000Z`)
- Commands requiring file access (catalog/overdue uploads) need docker exec
- **Traefik URL** (host accessible): `http://billing.62.171.153.219.nip.io`
- **Internal URL** (Docker network only): `http://killbill:8080`
- Always check logs after webhook events: `docker logs saasodoo-billing-service --tail 100`

## Troubleshooting

### KillBill Not Responding
```bash
# Check container status
docker ps | grep killbill

# Check health
curl -s "http://billing.62.171.153.219.nip.io/1.0/healthcheck"

# Restart if needed
docker restart saasodoo-killbill
```

### Webhooks Not Firing
```bash
# Check webhook configuration
curl -s -u admin:password \
  -H "X-Killbill-ApiKey: fresh-tenant" \
  -H "X-Killbill-ApiSecret: fresh-secret" \
  "http://billing.62.171.153.219.nip.io/1.0/kb/tenants/userKeyValue/PUSH_NOTIFICATION_CB"

# Check billing-service logs
docker logs saasodoo-billing-service --tail 100 2>&1 | grep -E "webhook|INVOICE|SUBSCRIPTION"
```

### Overdue States Not Triggering
```bash
# Verify payment method is default
curl -s -u admin:password \
  -H "X-Killbill-ApiKey: fresh-tenant" \
  -H "X-Killbill-ApiSecret: fresh-secret" \
  "http://billing.62.171.153.219.nip.io/1.0/kb/accounts/ACCOUNT_ID/paymentMethods"

# Check overdue config is loaded
curl -s -u admin:password \
  -H "X-Killbill-ApiKey: fresh-tenant" \
  -H "X-Killbill-ApiSecret: fresh-secret" \
  "http://billing.62.171.153.219.nip.io/1.0/kb/tenants/userKeyValue/OVERDUE_CONFIG"
```
