Can I use external media without being UTE?
Of course, a company can pull external media without being a UTE. That is, it is not necessary to set up a temporary union of companies to seek help outside - you can subcontract what you want: personal, equipment, materials, what you need to meet the requirements of a public tender.
Now, what is that of UTE and why people get into that mess? Basically, a UTE is like a band of companies that come together to introduce together a tender, because alone they do not even joke to fulfill everything they ask. Thus they can distribute responsibilities, resources and, of course, brown.
But, if you decide to throw only with external media and raisins of utes, eye, that is not so easy either. You have to have well -tied contracts, no word agreements or half things. If the external supplier fails, the brown is all of yours, because the administration will demand it to you, not them.
And if that were not enough, there is a tax and responsibility issue. If you hire people through an external supplier, the Treasury and Social Security may see you as the boss, and that means more paperwork and more obligations. I do not cool anything that caught your bull out there.
Total, yes, you can use external media without being UTE, but it is not to take a walk in the park. You have to know well what you sign, manage suppliers as if they were part of your team and, if necessary, ask for help from a good lawyer or advisor to save you from scares. In the end, the important thing is to present an offer that pete it and comply with what the tender asks for, either alone, in a group or with external help.
