What is the difference between a general invoice and a specific invoice?

General Invoices There are a number of general items that are in all invoices. Such as rows, product descriptions, unit prices, total sums, etc., but the specific invoice of all tables and items inside is different and is designed specifically for the same job. For example, the specific invoice of a gold shop can include description, gold gram, gold carat, daily price of that gold, packaging, etc., which is designed in the required style in the table.
