Why does a card transaction look pending and completed at the same time?

Start with the two-stage explanation, then verify it

A card purchase can first appear as an authorisation that reduces available funds, then as a completed transaction after the merchant finalises it. During the handover, an app may temporarily show both lines. That does not automatically mean two charges, but it also is not proof that everything is correct.

CommBank and ANZ describe these stages for their own accounts. Their display labels and timing are not universal, so use your bank's current help page and statement. This article is educational, is not a dispute decision or legal advice and receives no commission from the official links below.

Identify which balance each line affects

CommBank says its available funds or available card credit reflects what can be used now, while the account balance shown for a card does not include pending transactions. ANZ Plus says an authorisation is deducted from Everyday Funds while it is pending. These are issuer-specific descriptions, not definitions for every Australian bank.

Write down four fields for each line: merchant label, transaction date, amount and status. Then record the app's account balance and available amount at the same time. A screenshot taken later can show a different stage, so include the time and avoid combining observations from different days.

Reconcile a changing amount without double-counting it

Assume an account has A$900 available before a hotel authorisation. A pending A$140 authorisation leaves A$760 available under this simplified illustration. The hotel later submits a final A$155 transaction. If the final line replaces the authorisation and there are no other movements, the resulting available amount is A$745.

Do not subtract both A$140 and A$155 and call the purchase A$295 merely because both lines are visible during processing. First test whether the merchant, timing and reference indicate one purchase moving stages. The example assumes no other transactions and does not reproduce any bank's ledger formula.

Expect estimates where the final total is not yet known

ANZ Plus says hotels and car-rental businesses may use an estimated authorisation and can update it as charges accrue. That explains why the pending amount and final amount may differ without being two purchases. Ask the merchant what amount it authorised and what final amount it submitted.

An estimated authorisation can remain longer than an ordinary purchase in ANZ Plus. This is precisely why a single universal deadline would be misleading. Keep enough funds for the larger plausible final amount and check the issuer-specific timing before scheduling another payment from the same balance.

Use timing as a trigger to check, not as proof

CommBank says its pending payments generally process in three to five business days. ANZ Plus says pending transactions typically take five to seven business days and that estimated or incremental authorisations can take sixteen or more. Those windows belong to those issuers and products; they are not an industry guarantee.

If an unfamiliar line appears, use the bank's official contact route promptly rather than waiting just because it says pending. For a known transaction, follow your issuer's instructions on when a pending item can be queried or disputed. ANZ Plus says it cannot investigate a transaction while it remains pending, but another bank may use a different process.

Finish with a one-purchase reconciliation

Match the pending and completed lines by merchant, date, amount or changed amount, and any reference the app provides. Save one dated screenshot, the receipt and the merchant's final invoice. Then calculate available funds using one current stage—not both stages—unless the bank confirms there are two settled transactions.

Your next step is to open the bank's current pending-transaction guidance and label each app line as authorisation, completed or unknown. Recheck both issuer pages by 12 October 2026. If both lines settle, an amount is unrecognised, or the pending line exceeds the issuer's stated window, contact the bank through its official channel with the evidence.
