I have been a tax agent for 15 years. Throughout my practice as an accountant, I have met thousands of businesses. I understand that most business owners do not have a proper system for keeping documents. Especially, when they face a tax audit, they often feel frustrated. 

During the last MCO in 2020, I was fortunate to learn Python programming, one of the most popular programming languages. Given that the implementation of e-invoicing will have a significant impact on SME businesses, I have decided to dedicate myself to resolving these challenges together. 

Both How E-invoicing and How Self-billed are simple to learn and apply, especially since Excel files are familiar to everyone. Furthermore, they allow multiple suppliers/buyers and multiple line items to be submitted for validation in one go. There are no limitations—you can use Android, iOS, a laptop, or a desktop to work on them. This offers great flexibility and saves time.
