Why do travel agency accountants travel with tour groups?

Why do travel agency accountants travel with tour groups? It is an international practice to arrange government and business travel through travel agencies, and it is also one of the main businesses of foreign travel agencies. Because the travel agency has a certain scale of business, its price is often more economical and convenient than self-organized travel, so it can reduce administrative and commercial costs, facilitate post-event review and help standardize official travel activities. It is reported that at least 3 billion public funds flow into private pockets every year before the plane tickets are clearly marked and discounted. The unified arrangement and quotation of accommodation and transportation of travel agencies can not only effectively prevent corruption, but also save the administrative expenses of the unit as long as the management and operation are orderly and the promotion is orderly.
