B2C and B2B billing for US clients?

Question

Payment systems

Hey habr!
It is necessary on the site to make it possible to accept payments from both private clients and on behalf of companies.
It seems clear with B2C - companies like Recurly and Chargify allow you to do this.
Are there similar services for accepting payments from companies? Or a bank to this name?
I just don't know how it generally works on the internet right now. Always worked only on B2C.
We have a website, we sell services that can be used by both individuals and companies (SaaS). The service is provided immediately upon payment. And it is important to receive the service immediately after payment.
Payment amounts from $10 to $30,000.
