When you need commercial cleaning services, your first thought is likely a cleaning company that hires in-house staff. One Source does things differently, and you reap the benefits of this.
As a vendor management company, we outsource your cleaning services to the best and most suitable businesses. Before choosing them, we vet them closely and ensure they have a reputation meeting our demands. Plus, our relationship with them is ongoing. We give them feedback based on your input after every job to help them improve, and if they don’t meet our standards, we fire them and find a team that will do better by you.
We pay our teams by the job, not the hour, ensuring they have the necessary time to complete every project with care. Furthermore, we make sure all our services comply with state and local regulations, and we communicate with you regularly to keep you up to date on any work our teams complete for you.
At One Source, Inc., our name says it all. We strive to be your one-stop shop for all your commercial cleaning needs, ensuring you spend less time thinking about janitorial services and more time focused on the rest of your business.
