Running a medical shop in a Pharmacists name

My uncle is running a medical shop. Since he is not a pharmacist, he has employed a pharmacist to run the shop for a salary. But the medicines from the pharma companies are issued in the name of the pharmacist. The gross turnover per year is about 30 lakhs. The shop owner, my uncle is filing itr 4 u/s 44ad. Is this legally wrong? If there is scrutiny the medicine bills are in the name of the pharmacist, hence will there be a problem ?
