A topic of interest is in open specifications for interacting with government entities using electronic systems. As an example, KRA mandates use of approved ETA systems for VAT: https://kra.go.ke/images/publications/List-of-Approved-ETR-Suppliers--Manufa... Many of these systems transfer information over the internet to a KRA server: https://damitechsolutions.com/incotex-777-kra-tims-etr/ Having an API specification would enable easier integration tax payments into locally produced retail systems. In addition it would enable audit of the specifications for privacy and security. It would also enable companies to provide online accounting, reporting and remittance services, increasing efficiency, reducing compliance costs and still maintaining integrity with a high quality of service.
