Bid bond refers to the amount of liability guarantee provided by the bidder to the tenderer in order to ensure effective bidding during the bidding process.

Debit: Other receivables.

Loans: bank deposits

Debit: bank deposit

Credit: other receivables

3. When the enterprise returns the bid bond and the attached interest, the accounting entries are as follows:

Borrow: other monetary funds-security deposit

Loans: financial expenses-interest income

Other monetary funds refer to all kinds of monetary funds except cash and bank deposits, including foreign deposits, bank draft deposits, cashier's check deposits, credit card deposits, credit card deposits and investment deposits.

Do I need an invoice for the deposit?

No need to invoice. Invoice refers to the business vouchers issued and collected by all units and individuals in buying and selling goods, providing or receiving services and engaging in other business activities. They are the original basis of accounting, and also an important basis for law enforcement inspection by audit institutions and tax authorities. A receipt is a receipt for payment, and an invoice can only prove that the business has happened, but not whether the money has been received or paid.

Invoice refers to the text issued by the seller to the buyer in economic activities, including the name, quality and agreed price of the products or services provided to the buyer. In addition to the advance payment, the invoice must also have the elements paid by the buyer to the seller according to the agreed conditions, as well as the date and quantity, which are important vouchers for bookkeeping.

According to China's accounting system, valid invoices for purchasing products or services are called tax invoices. Government charge vouchers have different names in different periods and different charge items, but they are generally called administrative charge receipts. For internal audit and verification, each invoice must have a unique journal number to prevent invoices from repeating or skipping numbers.
