Accounting And AI: The Impact of Artificial Intelligence and Machine Learning

Generative AI and machine learning are shaking up financial processes, making them faster, smarter, and more strategic. These tools are transforming the game — and they’re doing it fast.

But we are still in the early stages, with unprecedented growth expected. The estimated market size for AI in accounting is $6.68 billion in 2025, with a projected increase to $37.60 billion by 2030, according to data from Mordor Intelligence.

A big factor behind the accelerated growth is advances in large language models and their support of generative AI. This has introduced unprecedented scale and pre-training on diverse datasets.

Let’s take a look at the current state of AI in accounting and finance and what the future holds.

AI in Accounting Today

The accounting industry has traditionally centered around meticulous number-crunching, complex calculations, and compliance-driven tasks. The demanding nature of this work has taken a toll on the accounting talent pipeline. Fewer students are pursuing accounting degrees, partly because the prospect of long hours spent on tedious, manual tasks is far from appealing.

However, AI is ushering in a new era where machines take on repetitive, rule-based functions, allowing accountants to focus on higher-value, strategic activities.

From automated data entry to real-time financial analysis, incorporating AI into accounting software streamlines financial processes and reduces the risk of human error. 

Here are some of the major functions incorporating AI:

Efficient Invoice Processing and Reconciliation

By some estimates, incorporating accounting AI into e-invoicing will save up to $28 billion in the next 10 years.

If that number is too big to wrap your head around, consider how many hours an AP team spends reconciling transactions with invoices. 

AI technologies, particularly optical character recognition (OCR) and machine learning (ML) algorithms, are pivotal in streamlining invoice processing. 

How exactly does AI simplify this process?

• Easy data extraction. OCR extracts relevant information from invoices, including invoice numbers, dates, line items, and amounts. AI automatically assigns transactions a category based on past behavior.
• Automatic tagging. Transactions are coded, tagged, and recorded in the general ledger automatically. This eliminates the need for manual data entry, reducing the likelihood of human errors and accelerating the overall processing time.
• Touchless AP. Users can choose to have invoice details coded at the line level by vendor or summarize the bill into one line item after the invoice is scanned. Generative AI and ML automatically populate the description and category, improving accuracy with every transaction.
• Smart reconciliation. Through pattern recognition and data analysis, AI systems can swiftly identify discrepancies and exceptions, flagging them for further review by human accountants. This expedites the reconciliation process and enhances accuracy by minimizing the risk of oversight.

In essence, AI transforms invoice processing and reconciliation from time-consuming manual tasks to efficient, accurate, and automated accounting processes that contribute to overall financial transparency and integrity.

Touchless Expense Reporting

Nobody likes filling out expense reports. Now, technology can take over that often-procrastinated task.

AI allows employees to simply take a photo of a receipt in the mobile app or submit it through a dedicated receipt inbox. The accounting technology takes it from there, automatically populating expense request details using the latest OCR technology. Built-in ML extracts the relevant information, including GL category, date, amount, and vendor, and generative AI fills in the purpose based on past patterns.

Fraud Detection

AI can analyze vast amounts of data far faster than any human.

The ability to simultaneously analyze financial data from diverse sources, including transaction history, user behavior, and external data feeds, empowers accounting professionals to uncover subtle signs of fraudulent activity that may escape human eyes. Suspicious transactions can be instantly flagged for further investigation.

AI is trained on historical fraud cases, so its detection skills are continuously evolving.

Budgeting and Forecasting 

AI in financial planning and analysis (FP&A) empowers data-driven decisions and helps organizations navigate complex financial forecasting with agility and precision.

By analyzing large datasets, AI can provide insights into market conditions, competitive landscapes, and other factors that affect planning and strategy.

Machine learning algorithms enable more accurate forecasting by analyzing historical data and identifying patterns and variables. This predictive capability supports accurate scenario planning and risk assessment.

AI-driven automation also takes over manual, routine accounting tasks like data entry and report generation so that the FP&A team can focus on strategic analysis.

Document Intelligence

AI can instantly identify key information from order forms and Service Organization Controls (SOC) documents to save time and improve accuracy. When built into intake workflows, AI extracts crucial data such as payment terms, auto-renewals, and pricing details. In Paylocity, generative AI prefills all of these purchasing details and GL links to reduce manual data entry.

AI can also scan SOC documents to detect and highlight potential exceptions and tested controls so approvers can efficiently review and manage related purchase requests within existing workflows.

Back-Office Functions 

Back-office functions are the administrative and support tasks critical to a company’s operations, including data entry, processing, payroll, and compliance activities. AI helps automate these repetitive tasks to save time.

But AI’s impact on back-office functions extends beyond mere task automation; it introduces a paradigm shift by leveraging continuous learning from historical data.

These systems evolve to handle intricate tasks that conventionally necessitate human intervention. AI then minimizes the inherent risk of errors in manual work, elevating the overall accuracy and efficiency of back-office business processes everywhere.

By harnessing AI’s ability to learn from experience, organizations benefit from streamlined operations, reduced reliance on repetitive manual efforts, and an enhanced ability to navigate complex and dynamic business environments.

Automating Bookkeeping Tasks 

Many bookkeeping and accounting tasks can be taken over by AI, including: 

• Categorizing transactions 
• Reconciling transactions 
• Data entry, including extracting information from receipts and invoices 
• Identifying errors and discrepancies in financial data 

It’s often said that AI will elevate the accounting profession by freeing up more time to focus on more rewarding value-added activities.  

Bookkeepers, on the other hand, do face declining job prospects. They can protect their career path by developing soft skills such as critical thinking, problem-solving, and effective communication. This can distinguish them in roles that require a human touch, such as client interactions and strategic financial advisory services. 

Proactively learning to integrate AI tools into their skill set can further enhance job security. 

Challenges of Adopting AI in Accounting and Finance 

Despite the many advantages, incorporating AI in accounting is not without challenges. Here's how to tackle those challenges head-on and make the case for AI efficiency. 

Hesitance Around New Technology 

A 2024 Thomas-Reuters survey revealed that 79% of accounting firms have no plans to adopt generative AI technology or are still considering it.  

One significant hurdle is the resistance often encountered within traditional accounting practices. Accountants may question the reliability of AI accounting software, particularly in areas requiring nuanced judgment or interpretation.
