Reconciling transactions at the end of the month can quickly become stressful. Managing multiple transactions, across several platforms, in huge volumes, is a mountain to climb for any financial institution. When every transaction needs to align perfectly, a single slip in record-keeping can end up drowning you in compliance risks, inaccurate reports, cash flow disruptions, and regulatory penalties.

It’s impossible not to be daunted by reconciliation as the calendar flips to the next month. Month-end reconciliation is the process of comparing and matching internal financial records against external sources, and with such a task at hand, there is no room for mistakes. With a good month-end reconciliation strategy ready to fire, you’ll be able to breeze through this period with half the worries.

Here, we’ll explore what month-end reconciliation is, why it matters, steps to automate the process, and the best practices for monthly reconciliations at your financial institution.

What are Monthly Reconciliations?

Monthly, or month-end reconciliation, is the detailed process of comparing your financial records, such as your bank and credit card statements, to your accounting records to ensure that they match. 

Depending on the use case, data can come from different sources. For instance, a loan reconciliation will need data from internal loan databases and external payment rails. Similarly, data for insurance reconciliation will come from settlement records, policy records, and premium payment records. For payment reconciliation, we will require bank statements, invoices, and receipts as source data.

For financial institutions, this can mean matching general ledger entries with documents like bank statements, payment gateway records, loan disbursement records, customer ledgers, and clearing accounts and avoiding discrepancies at all costs. 

The grind of month-end reconciliations comes with its rewards. Despite its troubles, monthly reconciliations are about accuracy and accountability. Coordination within the operations team, attention-to-detail, and regularly scheduled reconciliations can save you from regulatory non-compliance down the road.

How Month-End Reconciliation Works

Financial statements need to be balanced between the internal data sources, like ledgers and subledgers, and external sources and operational systems like payment processors, CBS vendor loan management systems, or more. Once the monthly reconciliation is completed and a reconciliation record has been made, it can be passed on to key stakeholders in your company. You can be sure of your overall financial integrity, and further decisions can be made based on the reconciliation report. Finally, you can rest assured that you’re keeping up with compliance requirements. 

Here’s the steps involved in a typical month-end reconciliation.

Month-End Reconciliation Workflow

1. Data Collection

Month-end reconciliations start by collecting all relevant data for the month. This relevant data will change, depending on the type reconciliation being done. 

For example, when doing a month-end loan reconciliation, data will likely be fetched from: 

  • The payment processor, such as a third party provider, a bank, or an internal company service, providing data on payment rails, Loan Management Systems, and Loan Origination Systems.

For an insurance reconciliation, these external data sources change:

  • Data from policy management systems, CRMs, third-party administrators.

And for a payment reconciliation, such as credit card or bank reconciliation, your data can include:

  • Bank statements, invoices, receipts, records in the accounting system.

For all reconciliations, your internal data sources will likely include the internal ledger, where all internal records of transactions are stored.

2. Data Standardization

Once this data is collected, cleaned, and transferred to a secure location, reconciliation can begin. Data usually comes in multiple formats and file types, such as CSV, JSON, XML, and more. This is influenced by what ecosystem partner you are getting the data from, too, such as payment gateways or loan servicing systems. This means they first have to be converted and standardized before the reconciliation process can begin. 

Doing this manually can be quite time consuming. However, with a platform like Osfin.ai, the standardization process is taken care of automatically and files are auto-matched and cleaned to remove discrepancies and duplicate entries. 

2. Matching Transactions

With the data foundation now established, the operations team will reconcile internal data with the external statements, aligning the transactions across their amounts, timestamps, and more. Challenges are apparent at this stage, as timing differences, aggregated payments, and currency differences can all add to the chaos. This process can be carried out manually, where each transaction is compared, or with an automation tool. The latter is definitely more efficient for larger institutions, with even larger volumes of data.

3. Checking for Discrepancies

When transactions are being reconciled, some discrepancies may be flagged–mismatched amounts, duplicate or missing entries. Maybe a customer payment has been recorded but not settled in the bank account. The operations team will look into these discrepancies further, investigating them, and making sure they’re addressed before they become too big to handle. 

Automation tools like Osfin.ai can be useful here. Not only can Osfin flag such discrepancies, but also label them appropriately with an accurate reason showing why they are still unreconciled, which helps the team address the issue and makes your records audit-ready.

At this stage, the team may need to double-check data sources, communicate with internal departments, correct errors, and review transaction histories, but it all builds up to the perfect month-end reconciliation report.

4. Document Preparation

With the discrepancies resolved and the data reconciled, all supporting documents are organized and compiled, creating a ready reference for the month's financial activities. This should include all matched transactions, discrepancies and their solutions, and additional comments for context. 

This audit trail keeps you prepared for internal reviews and regulation checks, making it stress-free for everyone involved.

5. Final Review

The final step in the monthly reconciliation process is the review of all reconciled transactions, usually by senior operations staff.  At this stage, the operations team is busy ensuring every discrepancy has been resolved, and that the financial statement meets the requirements of central banks and financial regulators. Once validated, these documents are locked and can be used for future decision-making.

Importance of Month End Reconciliation

An organized month-end account reconciliations process is a strategic move that impacts multiple areas of your organization.  

Importance of Month-End Reconciliation

There’s more than one way an organized month-end reconciliation can benefit your organization. Let’s break it down:

1. Maintain Your Financial Data

Accurate reconciliation ensures every transaction is accounted for. Balanced amounts in internal records align with external records, ensuring that your financial data is a true reflection of your position. 

2. Make Informed Decisions

With reconciled data at your fingertips, your decisions become better in a domino effect. Solid reconciliation gives executive teams a dependable foundation for budgeting and capital allocation, improving the quality of decisions made for the company.

3. Stay Compliant

If you work for a financial institution, you are well acquainted with the list of rules and regulations to be complied with. Month-end reconciliation helps meet these regulatory requirements on time and accurately. In the US, Sarbanes-Oxley Act (SOX) and Bank Secrecy Act (BSA) regulations define their requirement for financial monitoring, while Basel III and IFRS 9 are international frameworks. A month-end reconciliation reduces the risk of compliance breaches for these regulatory frameworks

4. Maintain Stakeholder Relations

Investors, board members, and partners want transparency and reliability. Month-end reconciliation shows that you’ve got things under control, building confidence with your stakeholders.

5. Stay Ahead of Problems

What if there are discrepancies in your records, duplicate entries, or unmatched trade settlements? Reconciling regularly helps catch these anomalies early, letting you soften the blow early on. This early detection contributes to the effectiveness of your financial operations, and prevents compliance issues. 

Another factor to consider is the rapid evolution of the financial industries. With new products or account types ready to be introduced at any point, make sure that your ledger documentation is adaptive to new changes.
