Open Billing › AWS Billing in the portal to reconcile infrastructure cost for your organization’s AWS account. This page is separate from both your wallet balance and the inference request log: An ECS task can therefore appear in AWS Billing and Financials without being an inference Event Log row. AWS Billing links the provider bill to the wallet; it does not create a second wallet ledger.

From a hold to a final charge

AI Reserve meters the AWS resources it can observe in near real time. Every five minutes it places wallet holds for running Fargate task time and load-balancer time. Holds keep long-running infrastructure from building a completely unreserved bill while AWS prepares its report. AWS later delivers a month-to-date CUR restatement. Each delivered line has:
  • AWS provider cost — the amount AWS billed AI Reserve;
  • AWS list amount — public on-demand pricing, or the public Spot market amount where Spot applies;
  • customer-policy amount — what your organization owes under the current AWS pricing policy;
  • hold matched — the part already reserved by real-time metering;
  • booked — an additional charge or credit posted after CUR arrived; and
  • outstanding — any difference still waiting for a wallet booking.
The page labels a line settled when its customer amount is fully covered by matched holds and bookings. A credit means CUR came in below an earlier hold or restatement. Deferred means the line is still waiting for a booking. Refused means the wallet lacked funds; the amount remains visible and retries after funds arrive. Generic booking failures are shown without exposing internal error details.
AWS can restate a line more than once. The opaque CUR reference and version shown in the portal are safe values to send support; they are not AWS credentials or wallet transaction ids.

​
Day and month status

AWS Billing closes on UTC days:
  • Open — CUR can still add or restate lines, or a wallet difference remains outstanding.
  • Settled — the day ended at least 48 hours ago and every delivered line is fully booked.
  • Final — AWS assigned invoice evidence and the scheduled month-close pass completed.
A settled amount is no longer waiting on known lines, but it can remain non-final until AWS invoices the month. The delivery-freshness indicator shows when the latest CUR delivery arrived. A delayed indicator means the page may understate very recent usage; it does not mean resources stopped running.

​
Amounts AI Reserve does not charge

Absorbed cost is provider cost for platform plumbing in the tenant account, such as AWS Config and CloudTrail. AI Reserve records it for reconciliation but does not charge it to your wallet. Provider credits, refunds, tax, and fee rows appear as AWS adjustments and are not automatically posted as customer wallet charges.

​
Load-balancer fixed-hour delta

The real-time load-balancer hold uses measured elapsed time, including the last partial hour. Implementing a separate fixed-hour minimum in the hold lane is deliberately deferred: CUR remains authoritative and applies any final provider-policy difference during settlement. This avoids charging the same fixed-hour delta once in a provisional hold and again in AWS’s final line. For the resource-metering scope, see Repoint Amazon ECS to AI Reserve.
