How do calculation credits work?
One completed calculation consumes one credit. Queries that fail validation or return no covered rate do not consume anything, and credits bought outright do not expire.
The Single Executive Report is a one-off purchase that includes one credit and the formal PDF export. Pro Pass grants 100 credits at the start of each monthly cycle, and a top-up pack adds 50 credits without changing the subscription.
A credit covers the full calculation: the complete duty, surcharge and VAT breakdown, the audit trail and the narrative risk commentary. Re-opening a report you have already generated does not cost a further credit.
When the balance reaches zero the interface offers a top-up or an upgrade rather than silently degrading the result. There is no partial or estimated output for an out-of-credit account.
