Handling Balance Sheet Reconciliation in the Automation Age

​​Balance sheet reconciliation: it doesn’t sound exciting, but it’s one of the most important checks in accounting. Accuracy is everything when your financial statements are concerned, and reconciliation is what upholds this. Done properly, it confirms that balances are complete, correct, and evidence-backed before statements are finalized.¹ Done badly, mistakes (and, sometimes, major control issues) can slip through – potentially leading to uncomfortable conversations with auditors and regulators in the future. So it’s essential to get this process right. 

‍

In this blog post, we look into what balance sheet reconciliation involves, why it matters, and how automation and AI can make it faster and easier to manage. 

What it is – and why it’s important 

Balance sheet reconciliation is the process of checking that the balances in your general ledger (GL) match the evidence behind them. That evidence might be bank statements, subledger reports, or detailed schedules that explain how each balance was calculated.

‍

The goal here is simple: making sure assets, liabilities, and equity balances are complete, accurate, and recorded in the correct period, as part of the broader account reconciliation process. Accurate reconciliations help to make sure financial statements present a fair, reliable picture of a business, whether under GAAP², IFRS³, or other reporting standards.

‍

For auditors and regulators, reconciliation is a key internal control over financial reporting. It’s one of the main ways for companies to show that the numbers in their external filings and reports can be trusted.

‍

Common examples include reconciling cash to bank statements, or matching accounts receivable (AR) and accounts payable (AP) balances to their aging reports. Any differences, like timing gaps or missing entries, have to be clearly explained and documented.⁴

‍

Strong reconciliations rely on clear procedures, capable preparers, and timely completion. These are all emphasized in internal control frameworks like COSO.

The traditional reconciliation process, step by step

For most accounting teams, balance sheet reconciliations follow a fairly consistent process. Some of the steps below might change depending on a business’ size and financial complexity, but the aim is always to make sure every balance in the ledger is backed up with evidence.

‍

1. List the accounts that need reconciling
   Start with a full list of balance sheet accounts. For each one, identify the supporting documents you’ll need – things like bank statements, subledger reports, contracts, or fixed-asset registers.⁵
2. Compare the ledger to the supporting records
   The preparer checks the GL balance against the independent source. Any differences should be flagged for deeper investigation.
3. Work out what caused the difference
   Some issues are normal timing differences (e.g. transactions still in transit). Others are true errors (e.g. missing, duplicated, or misclassified entries).
4. Fix errors while the period is still open
   If a discrepancy reflects an error or omission, a correcting journal entry needs to be posted so the financial statements reflect the right balance.
5. Get a final expert review
   A knowledgeable reviewer should check that the reconciliation truly supports the balance and isn’t just rolling forward last period’s numbers.
6. Focus attention where the risk is highest
   Accounts like cash, AR, AP, inventory, and key accruals should usually be handled with the highest priority, because errors there have the biggest impact.

Common challenges in balance sheet reconciliation 

Spoiler: a lot of the problems here come down to manual workflows and a lack of structure. Even though reconciliation is a fundamental control, it isn’t always easy to execute well. Many finance teams often run into recurring challenges:

‍

• Spreadsheet risks: When reconciliation’s done in spreadsheets, formula errors, missing items, or simple copy-paste mistakes happen. Over time, these ‘small’ issues can have a big impact on the balance sheet’s integrity.
• Inconsistent processes: If reconciliations aren’t handled the same way each period, or if procedures aren’t clearly defined, controls can break down and cause reporting problems.
• Heavy documentation work: Gathering evidence, attaching support, and documenting explanations can take up a surprising amount of time during the close.
• Limited visibility: If reconciliations live across a blend of emails, shared drives, and individual files (old habits die hard…), it’s difficult for leadership to see which accounts are finished, in review, or still outstanding.⁶
• Scaling problems as companies grow: As transaction volumes increase, manual reconciliation processes often struggle to keep up, raising the risk of missed issues or delayed reporting.

Best practices for handling the process effectively

Balance-sheet reconciliation works best when it follows a clear, consistent structure. One of the first steps is setting up formal policies that define which accounts need to be reconciled, who should prepare them, how often they should be completed, and what supporting documents are needed. Having these rules in place keeps the process consistent, even as companies and responsibilities change.

‍

A risk-based approach is also important. As we mentioned in the step-by-step overview earlier, higher-risk balances – cash, AR, AP, inventory, and major accruals – should always be reconciled before the close. Depending on your business’ size, lower-risk accounts might sometimes be reviewed using analytical checks instead of a full reconciliation.

‍

Strong internal controls also depend on a clear segregation of duties. Meaning that, ideally, the person responsible for processing transactions isn’t the same person preparing or approving reconciliations.

‍

Timing matters too. Reconciliations should be completed while the accounting period is still open – so if you need to make any adjustments, they can be posted before financial statements are finalized.

‍

Finally, bringing technology on board makes reconciliation more efficient. Automation can handle routine data collection and matching, so accountants get more time to focus on investigating unusual or complex items.

The future of balance sheet reconciliation

Balance sheet reconciliation is gradually moving beyond the traditional month-end routine. Many finance leaders are now working toward a “continuous close” model – meaning reconciliations and control checks happen more regularly, instead of being compressed into a few busy days at period-end. 

‍

Several trends are pushing this shift:

‍

• More automation in everyday processes: Routine matching, roll-forwards, and data gathering can run continuously rather than waiting for month-end.
• Predictive tools that flag issues early: AI models can identify unusual balances or suggest potential reconciliation matches before teams even start the close.
• Stronger digital audit trails for ICFR: Regulators increasingly expect reconciliations, approvals, and supporting documents to be clearly recorded and easy to trace.
• Broader reporting needs: New sustainability and ESG reporting standards depend on reliable financial data – which starts with well-reconciled balances.

‍

We’re looking toward a future where the routine parts of reconciliation happen automatically. Finance professionals' jobs are changing fast: there’s an increasing focus on reviewing exceptions, interpreting results, and tackling strategic work rather than manually matching transactions.

Where AI and automation fits in

AI and automation are changing how reconciliations are handled. To save accountants from manually comparing thousands of transactions, software can automatically collect data from ledgers, subledgers, and external sources, then apply matching rules to reconcile most items hands-free.

‍

AI-powered platforms take this idea further by recognizing patterns in historical reconciliations. Over time, they learn how transactions typically match and can suggest pairings even when amounts or references aren’t perfectly identical. Automation also improves exception handling, only flagging up items that genuinely need investigation, like unusual balances, missing entries, or duplicate transactions.

‍

Of course, this all has a big impact on the close process. As more reconciliation steps are automated, companies can shorten reporting cycles, put last-minute adjustments in the past, and feel more in control, keeping track of the process in real time.
