Navigating the world of invoicing can be challenging, whether you're embarking on a new business venture or dealing with invoices for the first time in a professional capacity. Understanding the nuances of what an invoice should contain is crucial.

Defining an Invoice

An invoice is a financial document generated by a business to detail services rendered or products sold, and similarly, businesses receive invoices from suppliers for their goods.

It's important to distinguish between an invoice and a tax document. The latter is specifically issued by VAT-registered entities, and therefore, they include slightly different components.

For VAT-registered businesses, every transaction must be accompanied by a tax invoice, which should encompass:

  • The names and details of the supplier and the customer,
  • The registered address of your company,
  • Company identification and VAT numbers,
  • Registration details in the Commercial Register,
  • Details of the services provided or products sold,
  • Dates of issue, due date, and completion of the taxable transaction,
  • Payment method and bank account details,
  • Information on the tax amount.

Invoices for Non-VAT Registered Entities

For non-VAT payers, such as entrepreneurs or self-employed individuals, the requirements vary based on whether they maintain formal accounts and their annual income. A significant threshold here is CZK 25 million.

The primary difference for non-VAT payers is the absence of VAT details and the format of the invoice number (which could be numerical or written, like invoice No. 202006).

Key details include:

  • Supplier and customer information (names and company names),
  • Your company's official address,
  • Company identification number,
  • Registration information in the Commercial Register,
  • Description of services or products sold,
  • Issue date, due date, and completion date of the transaction,
  • Payment terms and bank account information.
