Turning to in house staff for saving cleaning costs – hidden challenges in terms of pinching expenses

It has been witnessed that many offices in order to cut costs of Office Cleaning Services in Melbourne turn to in-house staff for cleaning and avoid outsourcing them to commercial vendors. It might look like a cost saving, but will turn out to be expensive due to certain hidden expenses. Let’s enlist a few of them.
Training costs - it might be easy to give orders but an untrained resource cannot handle the cleaning requirements of the commercial buildings. They need to be trained from scratch right from cleaning techniques to planned cleaning schedules and ensuring availability of items like toiletries or coffee cups etc. 
Supervisor cost - you need a dedicated resource to supervise all the in house cleaning staff because they are not professionals. Someone is needed in order to oversee what they are doing and ensuring they complete all the listed duties. This resource cost is additional.
Equipment and supplies – you will have to buy all the equipment and supplies by yourself, which is a higher cost than paying for an outsourced service using the same equipment and supplies.
Payroll costs -  on top of all this, since all these resources are hired by you, you will have to treat them as any other employee and pay their medical, insurance, provident fund etc. which is a big expense.
As compared to professional Office Cleaning Service in Melbourne, doing it in house is not just expensive but full of hassles.
