Taxora PRA is software that posts invoices to Punjab Revenue Authority on your behalf. PRA issues POS IDs and fiscal InvoiceNumbers. Taxora does not.
You must use sandbox, whitelist, and production tokens as PRA requires. Retry uses the same USIN. Do not create a second USIN for a sale PRA may already hold.
Print and QR are allowed only after Code 100. A queued or failed invoice is not a fiscal invoice.
Subscription invoices from Taxora are not PRA fiscal documents and must not be submitted to GetInvoiceNumber.
