I am a small-scale taxpayer. I don't have an invoice when I buy it, but I have to issue an invoice when I sell it. How do I keep accounts?

In fact, many enterprises have this problem. When you buy goods, you don't need an invoice, which means that your supplier has not issued a corresponding income invoice, which means that he probably has not declared his income, and of course his income has not been taxed, so you are evading taxes. Of course, the tax bureau is willing, and your account can't be balanced.

This is not good for you. Revenue-cost-expense = profit. If you have no cost, your company's profit will be high and the corresponding income tax will be high. You can work out the account yourself. 17% invoice or 25% income tax?

What you added later, many enterprises have it, because now it is a buyer's market, and the supply exceeds demand, so you can lower the price. If the negotiation is good, you can get 5% of the invoice of 17%, but you must pay at face value. Otherwise, it will be difficult to settle this account.
