• Adjusted books are 5190 less the unrecorded 40 fee, also 5150. I debit bank fee expense and credit cash for 40 because the statement reveals a book omission; I retain the source statement as support.
• I match individual transactions, dates and identities because equal totals can conceal offsetting missing or duplicate records. I inspect old outstanding items and make sure the opening balance agrees to the prior signed reconciliation.
• I retain the statement, item-level reconciliation, supported fee entry and reviewer approval because a zero difference alone isn't an audit trail. I leave genuine outstanding items open and assign investigation of stale ones rather than using an unexplained adjustment.

• One month of service earns 100, so I debit deferred revenue and credit service revenue 100. One month of insurance costs 100, so I debit insurance expense and credit prepaid insurance 100 because the case assumes even monthly recognition.
• Deferred revenue is 1100 and prepaid insurance is 500. Net cash from these transactions is plus 600; the October revenue and expense offset in profit, but that doesn't mean cash is unchanged. I reconcile both schedules to the ledger.
• I keep the contract and policy dates, schedules and journal support because recognition depends on the service pattern. I review remaining balances monthly, check cutoff and avoid recognizing the same month through both an automated schedule and a manual entry.

• I apply the supported credit to the payable with the offset to the relevant expense or inventory because its accounting must follow the original purchase facts. I don't treat a credit as a cash receipt unless money is refunded.
• I match the downloaded payment to the existing book transaction because adding it again would duplicate cash movement or expense. I verify account, date and payee as well as amount, then reconcile to the statement.
• I use approved supplier master data, duplicate detection and segregation of approval from payment where practical because one person approving an unchecked duplicate weakens the control. I reconcile the supplier statement and retain the invoice-credit-payment links.

• I debit service expense 900 and credit accrued liabilities 900 because expense recognition increases the obligation without a cash movement. The entry includes the supplier, service period and receipt reference so the later invoice can be matched.
• I clear the 900 accrual against the invoice and recognize the 40 difference under the close policy because posting all 940 as a new expense would duplicate October's amount. I compare the invoice detail with the estimate and determine whether the difference is new information or an error requiring correction.
• I reconcile the accrual schedule to the ledger and track subsequent invoices because a standing accrual can otherwise remain after settlement. I review unbilled receipts, assign aged exceptions and retain approval evidence rather than carrying forward unsupported balances.

• Standalone prices total 1560, so equipment receives 1300 times 1200 divided by 1560 equals 1000 units and support receives 300. I use relative standalone value because allocating the full list price to equipment would ignore the bundled discount.
• Equipment earns 1000 units and October support earns 300 divided by twelve equals 25, so October revenue is 1025. Deferred support revenue is 275 because eleven months of the support obligation remain; cash received was 1300 regardless of that recognition split.
• I retain contract terms, transfer evidence and the support schedule because a cash receipt alone doesn't establish performance. I reconcile the allocation and deferred balance to the ledger and review cancellation or modification terms before processing a later change.

Mid standard

• I compare opening agreement, invoice and cash batches, manual journals and failed-interface logs because each can change the control account or subledger differently. I trace transaction identity and posting date so offsetting errors aren't hidden by a net difference.
• I escalate the unresolved exception to the controller with the amount, evidence and remaining tests because materiality and close approval are authorized decisions. I distinguish a provisional internal report from a finalized close and document any approved limitation without asserting that 300 is immaterial.
• I match the control to the confirmed failure because a generic reminder may not prevent recurrence. For an interface failure I reconcile batch counts and amounts with owned exception alerts; for an unauthorized manual journal I restrict and independently review control-account postings.
