Automating bank reconciliation with Banking-as-a-Service

Data reliability, cash flow management and financial health: bank reconciliation plays a central role. It ensures consistency between bank statements and accounting entries. When performed manually or using spreadsheets, this process is time-consuming and exposes teams to a high risk of errors.
While many software solutions now exist to facilitate bank reconciliation, Banking-as-a-Service and API integration represent the most effective automation approach. Far more than a simple technical optimisation, this strategic transformation enables finance teams to gain efficiency and agility.

Bank reconciliation is a fundamental accounting process. It involves comparing transactions recorded in the bank account with the operations shown on bank statements provided by one or more financial institutions. This verification ensures that all transactions are accurately recorded and that the balance faithfully reflects the actual cash position available.

This operation requires the collection of a large amount of data from different sources:

• the general ledger extracts,
• bank statements for the relevant period,
• supporting documents for transactions (transfers, direct debits, cheques, card payments).

The objective is to match each line of the bank statement with the corresponding accounting entry. Unreconciled transactions are then recorded in a reconciliation statement, which explains the differences between the bank balance and the accounting balance at a given date.

Although complementary, it is important to distinguish bank reconciliation from account matching.
Account matching involves linking accounting entries together, such as an invoice with its payment, whereas reconciliation aims to validate consistency between two distinct sources of information: the bank and the accounting records.

Although it may appear easy to implement using an Excel spreadsheet, manual bank reconciliation has many drawbacks that heavily impact productivity and the reliability of financial management.

Manual matching of bank transactions is one of the most tedious administrative tasks. For companies handling a high volume of transactions, it is not uncommon for this process to require several hours, or even several days, of work each month. By automating reconciliation, up to 70% of the time spent can be reallocated to higher value-added activities such as financial analysis, cash flow management or payment flow optimisation.

The repetitive nature of manual reconciliation encourages human error. A missed line, an incorrectly entered amount or a transaction recorded twice can have significant consequences. Beyond their direct impact on cash accuracy, such errors can distort strategic decision-making, complicate audits and expose the company to penalties for non-compliance with accounting standards. Automation drastically reduces these errors and helps ensure compliance with accounting principles such as accuracy and consistency of methods.

Spreadsheets such as Excel, despite their popularity and ease of access, are not scalable tools suited to modern financial management needs. A lack of traceability, risks associated with formula changes, limited collaboration and difficulty managing multiple accounts simultaneously make them unreliable solutions once transaction volumes increase.

Faced with these constraints, automating bank reconciliation has become essential for companies seeking to optimise their financial management and remain competitive.
It transforms a tedious task into a smooth and secure process, allowing finance teams to focus on more strategic priorities: managing unpaid invoices, collections, negotiating supplier payment terms or preparing cash flow forecasts. This reallocation of resources represents a genuine growth lever.

Automating bank reconciliation relies on several technologies.
APIs enable a direct connection between a company’s banking data and its accounting software or ERP.
While Open Banking plays a key role in data access, Banking-as-a-Service provides greater control over flows and checks throughout the entire process.

Through an API interface, the company connects its various bank accounts to its management platform. This connection, secured by strong authentication, enables automatic aggregation of banking data in real time. Users benefit from a consolidated view of all their accounts directly within their management tool.

Based on rules defined by the finance department and analysis of bank transaction codes, descriptions and amounts, transactions are automatically assigned to the appropriate accounting categories.

Once the data has been categorised, automatic reconciliation between bank entries and accounting records takes place. Customer invoices, expense claims and other supporting documents are automatically matched with the corresponding bank transactions, without manual intervention.

The finance team focuses solely on reviewing the reconciliation statement and handling exceptions. At this stage, anomalies are identified: payment rejections, duplicate postings, fraudulent transactions or allocation errors.

Automating bank reconciliation delivers measurable and significant benefits for businesses.

Automation drastically reduces the time required for reconciliation, making it possible to produce a reconciliation statement in just a few clicks where several hours were previously needed. This increased efficiency frees up finance teams for higher value-added tasks.

Automatic recognition of transaction descriptions and amounts significantly limits the risk of human error, ensuring the reliability of accounting and financial data.

Thanks to continuous synchronisation, companies are able to anticipate their cash position in real time. This transparency improves the reliability of financial reporting and enables better strategic decision-making.

Automated reconciliation supports the detection of suspicious transactions, facilitates compliance with accounting standards and strengthens the robustness of internal controls (strong authentication, audit trail).
