COMPETITOR ANALYSIS
Notazz and Enotas are the most biggest platforms that automates the issuance of electronic invoices to digital entrepreneurs and online businesses offering integration service with platforms like Hotmart, allowing users to manage directly within their sales environment. From a UX/UI perspective they prioritize functionality and automation. However, the interface could benefit from enhanced visual hierarchy and more intuitive navigation to improve user experience.
