Prepare Transactions for the Monthly Close
Begin by establishing the month-end cutoff date and confirming that transactions for the period have been entered and reviewed. This includes vendor invoices, customer invoices, cash receipts, payments, inventory activity, sales transactions, and general ledger journal entries. Confirm that transaction dates and posting periods reflect when the activity belongs in the accounts.
Purchasing records deserve particular attention because goods or services may be received before a supplier invoice arrives. Reviewing requisitions, purchase orders, receiving records, and approvals helps finance identify obligations that belong in the current month. Purchase Order Automation: End-To-End Procedures & Benefits provides related context on connecting procurement controls with spend visibility and accounting records.
For businesses using multiple ERP-connected systems, confirm that relevant transactions have transferred into Sage 100 and that integration exceptions have been reviewed. An ERP integration strategy, such as the approach discussed in Closing Datacor ERP Finance Gaps with Hyperbots AI Agents, illustrates how finance workflows can be extended around an existing ERP environment.
Reconcile Accounts and Supporting Records
Month End Reconciliation is the process of comparing general ledger balances with supporting records to verify that the figures agree and are adequately explained. Common reconciliations include bank accounts, accounts receivable, accounts payable, inventory, fixed assets, and intercompany balances where applicable.
For each reconciliation, identify the account balance, compare it with the supporting schedule or external statement, investigate differences, and document the resolution. Timing differences should be distinguished from missing entries or coding errors. For example, an outstanding payment may explain a bank reconciliation difference, while a supplier invoice posted to the wrong account may require a correcting entry.
When several legal entities or business units report together, Month End Consolidation brings their financial information into a combined view according to the organization's consolidation rules. Confirm that entity-level balances and intercompany transactions are reviewed before consolidated results are finalized.
Review Accruals and Month-End Expenses
Accruals ensure that expenses and revenue are recognized in the period in which they are earned or incurred, in line with the company's accounting policies. Finance teams should review received-not-invoiced goods, services performed but not yet billed, utilities, freight, commissions, and other expenses that relate to the closing month.
For each estimated accrual, document the supporting evidence, calculation basis, general ledger account, amount, and expected reversal or settlement process. For example, if a business receives services worth $8,400 in April but the supplier invoice arrives in May, the accounting team may record an $8,400 April accrual if that amount is supported and appropriate under its accounting policy. The accrual is then cleared or reversed according to the company's established procedure.
The guide month-end closes discusses structuring accrual accounts and using reconciliation practices to identify discrepancies. GRNI Explained: Fix Hidden Month-End Liabilities offers additional context on goods received not invoiced and the importance of recognizing obligations before monthly reporting is completed. Cut-Off Date Accruals: 2026 Guide for Finance Teams also addresses accrual discovery, estimation, booking, and reversal around the reporting cutoff.
Post Adjustments and Review Financial Statements
After reconciliations and accrual reviews, prepare required journal entries for supported adjustments, reclassifications, depreciation, prepaid expenses, or other accounting items. Check the account coding, posting date, amount, description, and approval status before posting. Confirm that each entry affects the intended accounting period and retains adequate documentation.
AI-supported finance workflows can assist with activities such as document capture, data extraction, validation, and coding. In suitable workflows, invoice processing and straight-through processing can help move validated information through configured approval and posting steps. The Hyperbots Platform supports finance and accounting automation, while Process Specific Capabilities address distinct workflow requirements. Ready to Deploy Capabilities provide pre-trained agents and ERP connectors for suitable tasks, and Self Learning Capabilities use human feedback to refine supported workflows.
Once entries are posted, review the trial balance, income statement, and balance sheet. Compare results with the prior month, budget, or forecast, investigate material variances, and verify that significant balances have supporting schedules. Human in the Loop oversight keeps finance staff involved in exception handling and approval decisions. Use Company Specific Configurations to align supported workflows with the organization's ERP setup, roles, and general ledger structure.
Finalize and Certify the Month-End Close
Before treating the month as complete, confirm that required reconciliations, adjustments, reviews, and reports have been finished. Month End Certification is the documented confirmation that designated close tasks and control checks have been completed by the responsible individuals. A close checklist should identify task owners, deadlines, reviewers, unresolved items, and supporting evidence.
Store final reports and reconciliation records according to the company's document-retention policy. Period End Reporting provides the reporting view used to communicate financial results and support analysis. After authorized reviewers approve the results, follow the organization's Sage 100 procedures for period status and subsequent posting activity. Verify the exact steps for the installed version and modules before restricting or closing a period.
