Most companies don't need to become processors, only those who specialise in providing financial services to others.

Unless you have a very small company you already probably have an accountant or bookkeeper. In most situations, the e-invoicing is provided by your accountant as part of their comprehensive financial management solution. I pay about 120€/mo. for a solution that includes bookkeeping, electronic and traditional invoicing, electronic and traditional expenses management, salary/payroll and all tax declarations for my 1-person company. The effort saved/cost ratio is bonkers, and in the grand scheme of things the monthly fee is marginal.

There might be indeed a usecase for SMEs that don't want to buy a comprehensive financial management solution and instead want to send their e-invoices manually. It's probably a pretty niche usecase and someone could probably provide a "proxy" processor for something like 100€/year. It's still a very marginal cost for almost any imaginable going concern. And to receive any money you anyway need a bank account, which is not free for companies.

> That's my only negative point about this whole system is that money is being pulled away from freelancers and small SME's for every invoice they send.

I don't pay anything to send or receive e-invoices on top of my monthly plan. But I do pay a very small fee to my bank for each transaction they process.
