Employees don't invoice you, you pay them a salary. Contractors invoice you. If your team is contractors (or you're paying them as contractors for tax/liability/whatever reason), they invoice you and, if you're in the US, you should also ask for a tax form (usually a W8 or W9) based on where their tax residency is.
There's many apps/services to handle your payroll out there. Gusto comes to mind but I've never used it so I don't know what they're like. Some accountants / CFO firms also may handle payroll for you for a fee.
But really, I don't know your situation so ask that question to an accountant. There may be critical details you're not immediately aware of; your accountant will be.
Thanks!
How do most companies hire? Employees or contractors?
As far as I researched - most companies hire from outside the US as contractors. And they file invoices, and you pay the amount for it.
Do you know of companies that hire people from outside the US as employees and keep them on the same payroll?
Hiring non U.S.employees on your U.S. payroll is a bad idea. The employee will have a dual tax nightmare having to reconcile the tax and social security against their home country regime.
