How to shorten your month-end close

It’s the 12th of the month and last month’s close still isn’t done. One bank account is unreconciled because nobody downloaded the statement, the warehouse handed in its count late, and purchase invoices from three weeks ago turned up on someone’s desk. By the time the financial statements finally come out, management has already made the month’s decisions without them. And the following Monday, four adjusting entries are posted to a month that was supposed to be closed.

A long close is rarely about how fast your accountant works. It’s about order: tasks that depend on each other get done out of sequence, information arrives late and nobody knows who has the ball. This guide proposes a method you can apply starting next month.

The principle: move work before month-end

The biggest gain isn’t working faster in the first few days, but doing before the 30th everything that doesn’t depend on the 30th. Reconciling banks every week, reviewing the chart of accounts or chasing supplier invoices doesn’t have to wait for the close.

Ordered checklist

Order matters: each block uses what the previous one left behind.

1. Document cut-off. Set the cut-off date and time and communicate it. Everything sold, shipped, received and invoiced up to that moment goes into the month; the rest goes into the next one. Pay special attention to goods shipped but not invoiced and goods received without a supplier invoice.
2. Bank reconciliations. Every bank account and cash box, against its statement. Anything outstanding must be identified: deposits in transit, uncashed checks, unrecorded fees or debits.
3. Inventory. Close the month’s movements, match the stock ledger balance to the general ledger account and, if there was a physical count, record the differences.
4. Accounts receivable. Apply all collections, review the aging and reconcile the customer subledger to the general ledger.
5. Accounts payable. Record every invoice received, apply payments and reconcile the supplier subledger to the general ledger. If you received goods or services without an invoice, decide with your accountant how to recognize them.
6. Accruals and provisions. Utilities, professional fees, rent, interest and payroll provisions that belong to the month even if the invoice arrives later. Your accountant sets the criteria and parameters.
7. Depreciation. Review the month’s additions and disposals and post depreciation on fixed assets.
8. Taxes. Match the purchase and sales registers to the books before preparing the returns; your accountant confirms deadlines and forms.
9. Entry review. Trial balance, suspense or clearing accounts at zero, accounts with a balance opposite to their nature, and significant variances against the previous month.
10. Financial statements and period close. Issue them, review with management and lock the period so nobody can post to it anymore.

Day-by-day close calendar

Assume a target of closing on business day 5. One possible calendar:

Day	Tasks	Owner
Day −3 to −1	Cut-off reminder, bank reconciliation up to date, pending supplier invoices chased	Accounting, treasury
Day 0 (last day of the month)	Document cut-off, physical count if applicable	Sales, warehouse
Day 1	Bank statements, final reconciliations, inventory movements closed	Treasury, warehouse
Day 2	Receivables and payables reconciled to the general ledger	Accounting
Day 3	Accruals, depreciation, purchase and sales registers matched	Accounting
Day 4	Entry review and trial balance, variance analysis	Chief accountant
Day 5	Financial statements, management review, period locked	Chief accountant, management

If you close on day 12 today, don’t try to jump to day 5 at once. First set the calendar at day 10 and meet it two months in a row; then cut further.

Who does what

The close breaks down when everything depends on one person. Assign clear responsibilities:

• Sales: everything shipped is invoiced by the cut-off and the month’s credit notes are issued.
• Warehouse: movements closed and physical count delivered on day 1.
• Purchasing: supplier invoices handed to accounting, no drawers full of paper.
• Treasury: statements downloaded and banks reconciled.
• Accounting: accruals, depreciation, review and issuing the statements.
• Management: reviewing the statements and deciding on significant adjustments.

A shared list with columns for owner, committed date and status (pending, in progress, done) is enough so nobody has to ask.

Metrics for the close

Metric	How to calculate it	How to read it
Days to close	Business days from month-end to approved statements	The main metric; track it month by month
Post-close adjustments	Number and amount of entries posted to the month after it was declared closed	If high, the close is fast but not reliable
Old reconciling items	Bank reconciliation items older than 30 days	If they grow, someone is putting off postings
On-time tasks	Calendar tasks completed on their day ÷ total tasks	Shows which area is slowing the close

Suppose this month you closed in 9 business days, with 6 post-close adjustments totaling Bs 45,000, and 14 of the 20 calendar tasks were done on time (70%). The six late tasks tell you where to start. Be careful not to improve days to close at the expense of post-close adjustments: a 4-day close that gets corrected the following week isn’t a close.

Common mistakes

• Reconciling banks only at month-end: you pile up a month of differences instead of a week.
• Not defining the cut-off: sales and the warehouse cut on different dates and inventory never matches what was invoiced.
• Posting adjustments to a closed period without control: if the period can be edited freely, closing it means nothing.
• Keying in documents that already exist in another system: every transcription costs time and adds a point of error.
• Leaving the review for the end and discovering on day 5 an error from day 1.
• Not documenting the process: if the person who closes goes on vacation, the close stops.

If you want to automate it

With this calendar and a list of owners, a company can close in a few days even with spreadsheets. When volume grows, an ERP like MKA can generate entries from sales, purchases, collections and payments using posting rules you check in a preview, and close the period so it accepts no more postings (see accounting).
