Make the amounts comparable.

Compare the same period, currency and transaction population before treating a difference as an error.

Explain the movement from gross activity to a payout with supported components and an explicit unexplained difference.

A nonzero clearing balance needs a dated explanation; it is not automatically a mistake or a reason to zero the account.

Separate the settlement’s activity dates from its final payout date before comparing month-end totals.

Match a refund to its settlement treatment before expecting it to reduce the same period as the original sale.

A hold changes availability; a release is not automatically new revenue. Preserve the movement history.

A settlement with no positive transfer can still contain real activity and a useful accounting trail.

Reconcile source currency first, then explain the separate conversion and bank-currency view.
