5.Procedure

  1. 5.1

    Publish the close calendar

    Senior Accountant

    The senior accountant publishes the close calendar for the period, listing task owners and deadlines for subledger cutoff, accruals, reconciliations and review.

  2. 5.2

    Close subledgers and confirm cutoff

    Staff Accountant

    The staff accountant confirms accounts payable, accounts receivable and payroll subledgers are closed for the period, following their respective SOPs, and that no late transactions are missing cutoff.

    Checkpoint: Subledger totals used for close match the final accounts payable, accounts receivable and payroll reports for the period.

  3. 5.3

    Prepare and post accruals

    Staff Accountant

    The staff accountant prepares accrual entries for revenue earned or expenses incurred but not yet recorded, such as unbilled services or received but uninvoiced goods, with supporting calculations.

  4. 5.4

    Reconcile balance sheet accounts

    Staff Accountant

    The staff accountant reconciles assigned balance sheet accounts, including cash, prepaid expenses and accrued liabilities, tying the general ledger balance to supporting detail.

    Checkpoint: Every balance sheet account has a reconciliation with no unexplained difference before the close proceeds.

  5. 5.5

    Review fixed asset and depreciation entries

    Senior Accountant

    The senior accountant confirms the monthly depreciation entry from the fixed asset register has posted correctly and matches the fixed asset subledger.

  6. 5.6

    Review intercompany transactions

    Senior Accountant

    The senior accountant reviews intercompany charges and balances for the period, confirming they are recorded consistently on both sides and net to the expected amount.

  7. 5.7

    Run preliminary financial statements

    Senior Accountant

    The senior accountant runs preliminary income statement and balance sheet reports from the general ledger system once accruals and reconciliations are substantially complete.

  8. 5.8

    Prepare the flux analysis

    Senior Accountant

    The senior accountant compares account balances to budget and the prior period, and documents an explanation for any variance above the threshold set in the close calendar.

  9. 5.9

    Review and approve adjusting entries

    Controller

    The controller reviews proposed adjusting entries and the flux analysis, questions any unclear variance, and approves the final adjustments before the period is locked.

  10. 5.10

    Hold the management close review

    Controller

    The controller and CFO review the final financial statements and significant variances together before the statements are distributed outside the accounting team.

  11. 5.11

    Lock the period

    Controller

    Once the review is complete, the controller locks the accounting period in the general ledger system so no further postings can be made without a documented reopening.

    Warning: Reopening a locked period should require documented approval, since it affects reported results that may already be distributed.

  12. 5.12

    Distribute financial statements

    Controller

    The controller distributes the final financial statement package to management according to the standard distribution list and close calendar deadline.

  13. 5.13

    Archive close documentation

    Staff Accountant

    The staff accountant archives reconciliations, accrual workpapers and the flux analysis in the document management system, organized by period for future reference and audit support.

Perfect Wiki AIExample answer

One expense account is way higher than budget this month, what should I do before we close?

Document the flux analysis explaining the variance, checking for a timing difference, a missed accrual or a coding error, and get it reviewed before the controller approves the adjusting entries and locks the period.Source: step 5.8 ยท Prepare the flux analysis
