It is possible you have been using Viewpost for some time, and only now this information is being requested.
These questions are for you to answer and have no bearing on the vendor you are paying.
Because there are a variety of payment types it is possible that you did not receive this prompt in the past, and are now receiving it. All payment and customer types will need to provide Beneficial Ownership information.
This would be your individual information as a company owner. This information is only entered once, encrypted, and not visible to other users, or anyone on the Viewpost platform.
If you are not the owning party, or are unable to obtain that information, the pertinent party will need to fill out it out.
