Plant visits, supplier audits, project travel, across sites and state-wise GSTINs. In manufacturing, the defining problem isn't volume. It's entity complexity: credit that exists, filed to a registration that can't use it.
Mostly to one failure mode: the right invoice, filed to the wrong registration, invisibly.
An engineer flies for a plant project, is the invoice against the plant's GSTIN, the head office's, or the project company's? Get it wrong, and the credit is stranded in a registration that can't claim it.
Whatever GSTIN sits in the booking profile is what gets filed, usually head office, regardless of which plant the trip actually served. The airline isn't wrong; the routing is.
A filing against the wrong entity doesn't appear as a loss in anyone's report. It just sits, unusable, in a 2B nobody cross-checks against the others, which is why this leak survives good finance teams.
The switchboard below routes travel invoices to your state GSTINs, the way the airlines do it. Watch line two.
In a multi-GSTIN structure, the question isn't "was it filed?", it's "was it filed to the entity that can claim it?"
Your plants reconcile materials to the gram. Travel GST deserves the same disciplinerouted to the right registration, every ticket.
