Traditional accounting practices typically depend on centralized databases, which can be vulnerable to data manipulation, fraud, and security breaches. This paper proposes an innovative accounting system built on the Ethereum public blockchain, designed to effectively manage critical functions such as inventory management, customer interactions, sales transactions, and invoicing. By leveraging smart contracts, this system automates key processes—including invoicing and payments—resulting in reduced manual intervention and fewer human errors while improving operational efficiency. The decentralized framework of blockchain guarantees that every transaction is permanently recorded in an immutable ledger, offering unparalleled security and transparency. Additionally, this system reduces reliance on intermediaries, streamlining business operations and decreasing costs. However, challenges such as scalability and fluctuating transaction (gas) fees still persist within the Ethereum ecosystem. As Ethereum continues to evolve with the introduction of Layer 2 scaling solutions and Ethereum 2.0, these issues are anticipated to be resolved, positioning blockchain as a revolutionary solution for the accounting sector.
