Is it better to set up secondary subjects or auxiliary accounting for management expenses and financial expenses?

You can use it together. Detailed account and supplementary accounting do not conflict. Accounts with cross attributes such as income and expenses are very suitable for consolidated accounting. Generally, it is divided into different subsidiary accounts according to the nature of the business, and different auxiliary accounting according to the business object, so that your income and expenses accounting will be more clear. However, the workload is much greater. It is suggested that accounting computerization can be considered and determined according to the management needs of your company. If it is computerized accounting, it is very simple to set up auxiliary accounting. This option is available in the account properties. After the supplementary accounting is set for the parent account, the subordinate account will automatically have supplementary accounting, so it is not necessary to set it separately.
