Currently, the "New Client Onboarding Form" link from the Customer screen looks like https://billing.ourcompany.com/core/Registration but when visited, it redirects to https://ourcompany.flexpmts.com/core/Registration/CustomerBasicInfo and it should retain the custom white-labeled subdomain like the main portal does.

Also the "Client Payment Portal" and "New Client Onboarding Form" link descriptions use the word "Client" when the rest of the dashboard mostly uses the word "Customer" instead for the same thing. I personally prefer Client, but the terminology should remain consistent once chosen (either unchangeable, or if there was a preference for the terminology in Settings which would be nice).
