請問年終交給什麼交易資料給會計公司作AUDIT?

The auditor firm will ask you to supply what document is needed. But at least you have to give the above document.

Also all the vouchers, General Ledger, Stock List, Bank Book,Cheque Book, Saving & Muti Currencey Book, Account Receivable and Payable Reports, 銀行帳戶核對表 Bank Reconciliation...

存貨、購貨、銷售、貨倉 及 薪金、強積金...

The best is you can supply the Balance Sheet, Profit & Loss A/C otherwise the fee will be higher. More you can do, less you need to pay.

審計工作是要匯報公司業務狀況及於結算日之資產負債表。正常需要提供業務記錄(Business Records)在稅務局網頁中有小冊子列出。由你嘅問題我估你係屬於Shipping部門，而會計師一般祇會抽樣調查，所以不用掛心！
希望幫到你！
