Orders and invoices are different documents
An order records what was purchased and its fulfilment progress. An invoice is the official accounting document and exists only after it has been issued with its own invoice number. Keep both references when asking about a payment or activation problem.
Invoice access
Each invoice belongs to one client account and one Silurian country site. Access requires billing permission for that account on the matching country site. The same authorisation applies to the invoice record and its PDF; possessing a URL alone is not sufficient.
Checking your outstanding balance
The outstanding balance is the invoice total less payments already recorded. Payment is available only while that balance remains due. Paid, cancelled, refunded and zero-balance invoices do not accept another payment.
Paying by link, without logging in
An invoice email may include a unique, revocable payment link. It permits payment of that invoice without granting access to the wider account or stored payment methods. Opening the link does not create a charge; the payer must still complete the processor's payment flow.
How payment gets confirmed
An invoice becomes paid only after Silurian verifies an authenticated processor result whose invoice reference, amount and currency all match. Until that result arrives, retain the processor reference and do not start a second payment attempt.
