Month End Closing Checklist: What Actually Goes Into a Clean Close

At its core, the checklist covers four buckets: reconciling (bank, credit card, AR, AP), recording (accruals, deferrals, depreciation, payroll), reviewing (variance analysis, balance sheet review), and reporting (finalized statements, management commentary). A good checklist is a workflow with named owners and due dates attached to each line, not a static list someone printed once and forgot about.

Most businesses that come to us with a broken close have a checklist that exists only in one person’s head. That works fine until that person is on vacation, gets sick, or leaves. Then the close either slips or someone downstream inherits a mess they did not create.

A standard close, in order, looks like this:

1. Cut off the period: stop new transaction entry for the prior month and lock the subledgers.
2. Reconcile bank and credit card accounts against the general ledger.
3. Reconcile accounts receivable and accounts payable subledgers to the GL.
4. Record accruals for expenses incurred but not yet invoiced, and defer revenue not yet earned.
5. Post depreciation, amortization, and any inventory or WIP adjustments.
6. Review payroll postings and any related benefits or remittance accruals.
7. Run a variance analysis against budget or prior period and investigate anything that moves more than it should.
8. Review the balance sheet line by line: every account should have a reason for its balance.
9. Finalize statements and get sign-off from whoever owns the close.
10. Communicate results, not just numbers, to whoever is waiting on them.

That last step gets skipped constantly, and it is the one we push hardest on. In our view, doing a good job is two things: getting it done on time and accurate. But you have not done a good job until you have communicated it. A perfect close nobody reads or understands has not done its job.

Every close, regardless of industry, includes some version of: accrued expenses (utilities, professional fees, unbilled contractor time), prepaid amortization, depreciation on fixed assets, deferred revenue recognition for anything billed in advance, bad debt or allowance adjustments on aging receivables, and intercompany or clearing account cleanup. Clearing accounts in particular are worth watching. We regularly see staff clear a discrepancy with an adjusting entry instead of asking what caused it, which buries the actual problem instead of fixing it.

Our controllership teams run structured closes on a shared drive with a supporting-documents folder for each month, plus a formal review and sign-off step before anything is called final. That structure is the SOP, not an exception we make for careful clients.

We also push hard on what the controller role should look like day to day. A controller should be doing almost nothing as part of the month end itself: adjusting journal entries, reviewing, and that is it. The controller’s real job is training the team underneath them to do the work.

That is the difference between a close that scales and what we call the heroic close: one person doing everything by hand, holding the whole process together by memory and effort. It works right up until volume grows, that person is out sick, or the file gets more complex. A five-day close is a point of pride for our controllers, and it is only possible because the work is distributed and documented, not hoarded.

A checklist is not the same thing as controls. You can complete every line on a checklist and still have no segregation of duties, no second set of eyes on payments, and no real audit trail. We apply a processing-plus-approval model on payables specifically because a checklist alone will not catch someone with too much unchecked authority over cash.

It is also not a one-time cleanup. Businesses often confuse a deep cleanup after books have drifted with an ongoing close process. The cleanup gets you current. The checklist keeps you current.
