Can the company buy food with self-employed people?

Of course. Self-employed individuals can issue invoices and go through the formalities of receiving and purchasing invoices at the competent tax authorities. When the company buys vegetables from the self-employed, the self-employed can issue invoices and reimburse them in the company's finance, so the company can buy vegetables with the self-employed. Self-employed is the common name of urban and rural individual industrial and commercial households, and is a self-reliant worker who does not exploit others within the scope permitted by our laws.
