Hello. Can you please advise me on the best way to solve the issue of cleaning in the office? Is it worth hiring a person who will do the cleaning every day or is it better to sign a contract with a cleaning company?

I disagree. I think it is too expensive to hire such an employee. You'd have to pay taxes on the salary. Plus buy household chemicals and all sorts of equipment - all these costs will fall on you. So my advice to you - it is better to think contract in the cleaning company. It will be much more profitable. Here you can find out the domestic cleaning prices: https://briiz.com.mt/ .
