# Trade Accounting

Run your trading operation like a business. Every SOL spent, every token acquired, every fee paid, every gain realized — tracked with double-entry bookkeeping so your books always balance. Whether you trade through a personal wallet or an LLC, proper accounting turns chaos into clarity.

**Core principle**: Every transaction touches at least two accounts. Buy a token? Cash goes down, token holdings go up — by the same amount. This double-entry constraint catches errors automatically: if debits do not equal credits, something is wrong.

## Why Traders Need Accounting

Most traders track P&L loosely — "I started with 50 SOL and now I have 62 SOL." That tells you nothing about:

- How much came from realized trades vs unrealized positions
- What you paid in cumulative fees (gas, priority fees, swap fees)
- Whether your staking and LP income covers your operating costs
- Your actual cost basis for each holding (critical for taxes)
- Cash flow timing — are you profitable but illiquid?

Proper accounting answers all of these. It also separates **trading P&L** (mark-to-market, useful for strategy evaluation) from **tax P&L** (realized gains using a specific cost basis method, required for compliance).

## Account Types

A trading operation uses four account categories following standard accounting:

| Category | Normal Balance | Examples |
|----------|---------------|----------|
| **Assets** | Debit | Cash (SOL/USDC), token holdings, LP positions, staking deposits, receivables |
| **Liabilities** | Credit | Margin borrowing, accrued taxes payable |
| **Income** | Credit | Realized trading gains, staking rewards, airdrop income, LP fee income |
| **Expenses** | Debit | Trading fees, gas/priority fees, subscription costs, data feeds |
| **Equity** | Credit | Owner capital contributions, retained earnings, withdrawals (contra) |

## Double-Entry Bookkeeping

Every transaction records equal debits and credits. Debits increase asset and expense accounts; credits increase liability, income, and equity accounts.

### Entry Examples

**Buy 1000 BONK for 0.5 SOL (0.001 SOL gas fee):**

| Cash – SOL | | 0.501 SOL |

Or with the fee broken out explicitly:
