A Full Guide to Preparing Primary Documents for Novice Entrepreneurs

What is a primary document?

Primary documents are the foundation of any accounting system. They serve as a record of each economic transaction and include documents such as contracts, invoices, bills of lading, certificates of completed works, and others. These documents confirm the fact of transactions and serve as the basis for all subsequent accounting entries and reports.

The Importance of Accuracy and Precision

Accuracy and precision in preparing primary documents are essential for ensuring legality, transparency, and efficiency in business management. Errors or oversights can lead to financial and legal issues.

Fundamentals of Documentation for Non-VAT Payers (Value Added Tax)

If you are not a VAT payer, the primary focus when preparing documents should be on the content of the transaction, the period in which it was made, and its key parameters - quantity, price, and total amount. When dealing with companies, additional information will be required, including data about your and the client's company, as well as the document number. In other words, taking any primary document from such a company, it should be clear what happened, what goods or services were sold, when it happened, who was involved in the transaction, and the volume, amount, and cost of the deal.

Requirements for VAT (Value Added Tax) Payers

In addition to the requirements mentioned in the previous paragraph, VAT payers must consider additional requirements such as the invoice issue date, addresses of the parties involved, VAT registration number of the payer, price excluding VAT, VAT amount, total transaction amount in euros, tax rate, and the date of service provision or goods delivery if it differs from the invoice issue date. This level of detail is necessary for accurate and correct tax accounting.


There are transactions for which simplified documentation is permissible. For instance, when selling transport tickets or using vending machines for goods and services. In these cases, it's necessary to state the date, VAT payer's information, description of the goods or services, as well as the amounts with and without VAT. You can read more about this in this article.

Specialized Documents and Reports

Various situations require different types of documents. For example, there are reports for travel expenses, operational expenses, and route sheets. Each of these has its own structure and requirements for preparation.

Practical Tips

  • Planning: Develop a system for recording and preparing documents in advance.
