What Our Students Love

I have taken two interesting courses on e-invoicing. The 1st one on mandates, country and business segments requirements and actual practice and the 2nd one on e-invoices formats, coding languages. Both helped me to be oriented in the status of requirements and stage of adoption per country, and provided me lots of useful information, links and sources where to find out information. I liked the training, both videos and handouts forms, very nicely structured, good flow and nice presentations done by Peter from RSAgile. I also liked practical examples.

Also, there is a tutorial on how to create your own simple e-invoice using XML language - even for real code beginners like me :). I really recommend courses for all who are responsible for e-invoicing topic and specifically adoption in their companies or even for people with general interest. Armed with the knowledge obtained from your school, I feel more equipped to navigate the challenging aspects of the real world and become a professional in my field of choice.

This online course is fantastic. The speaker is excellent, and the course has exceeded my expectations. I appreciate all the hard work the speaker has put in. I highly recommend it to all accountants or finance teams.

Absolutely FANTASTIC experience! I've just learned the XML language (my first programming language!) and also created the first e-invoice in less than an hour. I am so excited.

Peter's teaching style is exceptional; he effortlessly explains complex topics in a simple and straightforward manner and leaves details in comprehensive PDFs for further exploration. This was truly one of my best learning experiences.

Having taken an accounting course two years ago, I now wanted to learn basics about e-invoicing and formats, and Peter's course exceeded my expectations. I looking forward to his next courses on this subject.

I was looking for another Peter’s course, which is great again! This course by Peter has quality, comprehensive information, and excellent supplementary materials.

Many countries are trying to implement e-invoicing mandates, each with different rules, Peter calls it a jungle. But he found six real-world scenarios representing the mandate situations in all actual countries. Thanks to this I could understand it easily and quickly.

Something extra for me - I often struggled to search and verify information about a difficult topic. But now I have gained valuable skills in searching and validating requirements in any country, which I will apply in other work areas. Peter's ability to make complex subjects accessible is truly remarkable. I highly recommend this course and eagerly look forward to Peter's next offerings!
