When the system refuses

It needs a company or an agent first

A booking billed to somebody else needs that somebody on file.

The booking says it is billed to a company or an agent, and none is named.

Create the company or agent first, with its billing address and GSTIN. A company billed without a GSTIN produces an invoice they will send back.
A company may have branches; the booking is billed to a branch, because that is what the invoice is addressed to.
An agent carries a commission, which is why an agent booking is not the same as a company booking even when the same firm does both.

Until the party exists, bill the folio to the guest and change it before check-out — changing it afterwards means cancelling and re-raising the invoice.
