All our experts should be able to provide you with an invoice for the service they provide through Peerwith. However, most of these experts are self-employed individuals, most of them are not tax registered and/or "official" companies. Especially in cases where you need your institution to make the payment, this might become an issue.
This is why we (Peerwith) offer the Institutional solution. We can do consolidated billing and "collect" the invoice(s) on your behalf, and forward them as an invoice coming from Peerwith, a company registered at the Dutch Chamber of Commerce.
