This app is a dedicated app that allows Naris cosmetics dealers who have a commission contract with Nakamura Accounting Office to easily create books. Since there were many requests from dealers who are not good at personal computers and want to create sales tables and expense books on smartphones while on the move or during breaks, Nakamura Accounting Office has developed its own app.The books that can be created are "Business member sales table", "General sales table", "Esthetic sales table" and "Expense book". If you have a smartphone, invoices, receipts, passbooks, etc., you can easily create books on the spot, so please download the app and use it. * To use the app, you will need the ID and PW issued by Nakamura Accounting Office. Also, the ID and PW are different for each person.
