## QBO Specifics Implemented

✓ **SyncToken** - Required for all updates (optimistic locking)
✓ **SQL-like queries** - Full support for `SELECT * FROM Entity WHERE ...`
✓ **Pagination** - 1-indexed startPosition + maxResults (max 1000)
✓ **Report endpoints** - Special handling via `getReport` method
✓ **Void operations** - Proper handling via delete with operation parameter
✓ **Entity reads** - Standard `/company/{realmId}/{entityType}/{id}` pattern

## Tool Naming Convention
All tools follow the pattern: `qbo_verb_noun`
- Examples: `qbo_list_invoices`, `qbo_create_customer`, `qbo_run_profit_loss`

## TypeScript Compliance
✓ All files compile without errors (`npx tsc --noEmit`)
✓ Proper imports from `../clients/quickbooks.js`
✓ Type-safe handlers with QuickBooks types from `../types/index.js`

## Next Steps
1. Update `src/server.ts` to import and register all tool files
2. Test with actual QuickBooks sandbox credentials
3. Add integration tests
4. Update README with tool documentation
