hello, dear. I'm glad to answer your question. The method/steps about how to add notes to electronic invoices are as follows: 1 Enter the invoicing system and click Invoice to fill it out. 2 Click on the general invoice. 3 Enter the invoice page and click the remarks box. 4 Enter the contents that need to be noted. There are 7 categories that need to be noted: cargo transportation services, construction services, real estate sales, real estate rental, differential tax invoicing, prepaid card sales, and others. 5 Finally, click Open.
