# Source

The `source` field in `sourceOfFunds` declares the origin of the funds being sent. The available values depend on who is sending and receiving.

## Individual to Individual

Use these values when both the sender and recipient are individuals:

| **Value** | Source          | When to use                                              |
| --------- | --------------- | -------------------------------------------------------- |
| **1**     | Salary          | Funds from regular employment income                     |
| **2**     | Savings         | Personal savings or accumulated funds                    |
| **3**     | Lottery         | Lottery or gambling winnings                             |
| **4**     | Loan            | Borrowed funds (personal or bank loan)                   |
| **5**     | Business Income | Revenue from a personal business or freelance work       |
| **6**     | Business Profit | Profit distributions from a business the individual owns |

## Business Transactions

Use these values when either the sender or recipient (or both) is a business entity. Applies to: Individual → Business, Business → Individual, and Business → Business transfers.

| **Value** | Source     | When to use                                                 |
| --------- | ---------- | ----------------------------------------------------------- |
| **7**     | Settlement | Payment settlement between businesses (invoices, contracts) |
| **8**     | Others     | Any source not covered by the above categories              |

## Example

A freelancer sending business income to family:

```json
"sourceOfFunds": {
  "purpose": 3,
  "source": 5,
  "relationship": 2
}
```

* **source: 5** → Business Income (freelance earnings)
* **purpose: 3** → Family Maintenance
