## Common Queries

### Unpaid Bills by Vendor
```sql
SELECT v.Name, b.BillNumber, b.BillDate, b.Amount, b.AmountDue
FROM Bills b
JOIN Vendors v ON b.Vendor = v.id
WHERE b.Status IN ('Open', 'Partial')
ORDER BY b.DueDate
```

### Bills Summary by Vendor
```sql
SELECT v.Name as Vendor, COUNT(b.id) as Bills, SUM(b.Amount) as Total, SUM(b.AmountDue) as Due
FROM Bills b
JOIN Vendors v ON b.Vendor = v.id
GROUP BY v.Name
ORDER BY Total DESC
```

### Account Balances (Non-Zero)
```sql
SELECT Code, Name, Type, Balance
FROM Accounts
WHERE Balance != 0
ORDER BY Code
```

### Owner Reimbursement Balance
```sql
SELECT Balance FROM Accounts WHERE Code = '2203'
```

### Expense Summary by Account
```sql
SELECT a.Code, a.Name, a.Balance
FROM Accounts a
WHERE a.Type = 'Expense' AND a.Balance != 0
ORDER BY a.Balance DESC
```

### Transaction History for Account
```sql
SELECT t.Date, t.Description, t.Reference, tl.Debit, tl.Credit
FROM TransactionLines tl
JOIN Transactions t ON tl.Transaction = t.id
WHERE tl.Account = {account_id}
ORDER BY t.Date DESC
```

### Verify All Transactions Balance
```sql
SELECT id, Description, Total, IsBalanced
FROM Transactions
WHERE IsBalanced = false
```

## Financial Reports

### Balance Sheet

Shows Assets = Liabilities + Equity at a point in time.

**Important:** Parent accounts roll up child balances. Query only top-level parents (Parent = 0) to avoid double-counting.

```sql
-- Assets, Liabilities, Equity (top-level only)
SELECT Code, Name, Type, Balance
FROM Accounts
WHERE Type IN ('Asset', 'Liability', 'Equity')
  AND Parent = 0
ORDER BY Type, Code
```

```sql
-- Net Income (for Equity section)
SELECT
  COALESCE(SUM(CASE WHEN Type = 'Income' THEN Balance ELSE 0 END), 0) -
  COALESCE(SUM(CASE WHEN Type = 'Expense' THEN Balance ELSE 0 END), 0) as NetIncome
FROM Accounts
WHERE Type IN ('Income', 'Expense')
  AND id NOT IN (SELECT DISTINCT Parent FROM Accounts WHERE Parent != 0)
```

**Presentation:**
| **Assets** | |
|---|---:|
| Cash & Bank Accounts | $X.XX |
| Accounts Receivable | $X.XX |
| **Total Assets** | **$X.XX** |

| **Liabilities** | |
|---|---:|
| Accounts Payable | $X.XX |
| Due to Owner | $X.XX |
| **Total Liabilities** | **$X.XX** |

| **Equity** | |
|---|---:|
| Retained Earnings | $X.XX |
| Net Income (Loss) | $X.XX |
| **Total Equity** | **$X.XX** |

| **Total Liabilities + Equity** | **$X.XX** |

### Income Statement

Shows Revenue - Expenses = Net Income for a period.

```sql
SELECT Code, Name, Type, Balance
FROM Accounts
WHERE Type IN ('Income', 'Expense')
  AND Balance != 0
  AND id NOT IN (SELECT DISTINCT Parent FROM Accounts WHERE Parent != 0)
ORDER BY Type DESC, Code
```

**Presentation:**
| **Income** | |
|---|---:|
| Service Revenue | $X.XX |
| **Total Income** | **$X.XX** |

| **Expenses** | |
|---|---:|
| Software & Subscriptions | $X.XX |
| Professional Services | $X.XX |
| **Total Expenses** | **$X.XX** |

| **Net Income (Loss)** | **$X.XX** |

### Trial Balance

Lists all accounts with non-zero balances. Debits should equal Credits.

```sql
SELECT
  Code,
  Name,
  Type,
  CASE WHEN Type IN ('Asset', 'Expense') THEN Balance ELSE 0 END as Debit,
  CASE WHEN Type IN ('Liability', 'Equity', 'Income') THEN Balance ELSE 0 END as Credit
FROM Accounts
WHERE Balance != 0
  AND id NOT IN (SELECT DISTINCT Parent FROM Accounts WHERE Parent != 0)
ORDER BY Code
```

### Accounts Payable Aging

```sql
SELECT
  v.Name as Vendor,
  b.BillNumber,
  b.BillDate,
  b.DueDate,
  b.AmountDue,
  CASE
    WHEN b.DueDate >= strftime('%s', 'now') THEN 'Current'
    WHEN b.DueDate >= strftime('%s', 'now') - 2592000 THEN '1-30 Days'
    WHEN b.DueDate >= strftime('%s', 'now') - 5184000 THEN '31-60 Days'
    ELSE '60+ Days'
  END as Aging
FROM Bills b
JOIN Vendors v ON b.Vendor = v.id
WHERE b.Status IN ('Open', 'Partial')
ORDER BY b.DueDate
```

## Reconciliation Queries

### Cleared Balance for Bank Account

Use `get_records` to avoid the `Transaction` reserved word issue:

```python
# Step 1: Get all TransactionLines for Checking (id=14)
lines = get_records("TransactionLines", filter={"Account": [14]})

# Step 2: Get cleared transaction IDs
txn_ids = list(set(line["Transaction"] for line in lines))
cleared = sql_query(f"SELECT id FROM Transactions WHERE Status = 'Cleared' AND id IN (...)")
cleared_ids = set(row["id"] for row in cleared)

# Step 3: Sum Debit - Credit for cleared lines
cleared_balance = sum(
    line["Debit"] - line["Credit"]
    for line in lines
    if line["Transaction"] in cleared_ids
)
```

### Outstanding Items (Not Cleared by Bank)

```sql
SELECT t.id, t.Date, t.Description, t.Status,
       tl.Debit, tl.Credit
FROM TransactionLines tl
JOIN Transactions t ON tl.Transaction = t.id
WHERE tl.Account = 14
  AND t.Status != 'Cleared'
ORDER BY t.Date
```

### Reconciliation History

```sql
SELECT id, StatementDate, StatementBalance,
       ClearedBalance, Difference, Status
FROM Reconciliations
WHERE Account = 14
ORDER BY StatementDate DESC
```

### Active Bank Rules

```python
get_records("BankRules", filter={"Account": [14], "IsActive": [true]})
```
