Bad: not free. Sometimes it's controlled by people. For example, when signing a contract and other external matters, you must issue official seals, financial seals, copies of business licenses and other things, and also apply to affiliated units. If you don't have your own independent account, the customer's funds are in the account of the affiliated unit, and it will be very troublesome to withdraw money.
In fact, it is more complicated for a company's financial affiliation to the company, mainly in tax treatment, because VAT is not only the output tax generated by sales, but also the input tax generated by purchase, and income tax should also be considered. Therefore, as yourself: 1, you should consider paying the value-added tax. If there is no VAT input invoice, you can negotiate to pay *% VAT to the affiliated company without calculating how much VAT to pay for each business. 2. Consider paying the income tax payable. Of course, we can negotiate to use the expense sheet to offset the profits, so that we don't have to pay corporate income tax. 3. It is very simple to use the funds alone: open a settlement account and control the private seal yourself. 4. If the external legal effect of the affiliated agreement is very low, you'd better appear in the form of the business department of the affiliated company, otherwise the tax department will think that the affiliated company has falsely made out the value-added tax, and the punishment is very heavy.
