Unlock Efficiency: A Step-by-Step Guide to Generative AI for Accounts Payable and Beyond

Generative AI, like ChatGPT, is rapidly transforming how businesses operate, especially within finance departments. With hundreds of millions of users, this powerful technology from OpenAI offers unprecedented opportunities to boost productivity and streamline operations.

This article explores practical applications of generative AI in accounting, providing a step-by-step guide to generative AI for accounts payable and highlighting its broader impact. We’ll show you how to leverage AI for tasks ranging from financial analysis to business communications, always emphasizing the importance of human oversight.

What Exactly is ChatGPT?

ChatGPT is a sophisticated generative AI model developed by OpenAI, leveraging natural language processing (NLP). It functions as a conversational AI chatbot, designed to understand and respond to user queries with human-like text, images, or audio.

This advanced tool uses a multi-layered deep learning neural network, a subset of machine learning, to process information. Through API integration, other software applications can also incorporate ChatGPT’s powerful functionalities, extending its reach across various platforms.

Understanding ChatGPT’s Current Limitations

While incredibly powerful, ChatGPT is not without its limitations. Its effectiveness largely depends on the quality of your input and your ‘prompt engineering’ skills. Human judgment, fact-checking, and iterative refinement of outputs remain crucial for accuracy and relevance.

OpenAI also advises against entering sensitive information due to ongoing privacy and security considerations. Furthermore, its core training data has a cutoff date (September 2023 for GPT-4o, November 2023 for GPT-4). However, newer features like ‘Search’ and ‘Deep Research’ allow access to more current information.

12 Smart Ways to Use Generative AI in Accounting

Generative AI can significantly enhance various accounting functions. Here are twelve practical applications that human accountants can explore:

1. Streamlining Invoice Processing

Generative AI can assist with aspects of invoice processing, such as coding expenses. However, for maximum efficiency and accuracy, integrating AI features directly into AP automation software, like Tipalti, offers superior results.

Tipalti’s AP automation, for example, uses embedded ChatGPT features to enhance account coding predictions and improve purchase order matching. This integration is crucial for effective end-to-end payables and automated invoice processing, including global payments.

2. Automating Expense Coding

While you can use ChatGPT to attempt coding expenses to your chart of accounts, dedicated AP automation software with built-in AI proves far more accurate and efficient. Solutions like Tipalti AP automation, combined with Tipalti Expenses, provide seamless employee expense reimbursement and automatic coding.

This digital transformation eliminates manual data entry, reduces payment errors by an impressive 66%, and strengthens financial controls. Tipalti’s robotic process automation (RPA) identifies exceptions and saves businesses up to 80% of the time spent on payables processes.

3. Enhancing Data Cleansing

Generative AI can effectively clean accounting data. For instance, you can use it to remove unnecessary characters from customer names or eliminate duplicate entries in spreadsheets and customer master files. This step is vital before migrating data to new software systems, ensuring data integrity.

4. Formatting Financial Output

If your current accounting software’s financial statements or reports don’t meet your formatting preferences, ChatGPT can help. You can input files and use prompts to reformat financial statements, reports, tables, and even generate CSV files for imports or other applications.

5. Crafting Report Narratives and Notes

Leverage generative AI to create narratives, notes, and visualizations for financial reports and statements. It can analyze significant changes in account balances, revenues, expenses, and profitability across comparative periods, offering suggestions for improvement in internal reports.

For formal notes to financial statements, always fact-check and supplement AI-generated content with the latest GAAP or IFRS standards. ChatGPT can also assist public company CFOs in preparing conference call scripts and anticipating questions from financial analysts.

6. Generating Computer Code

Need custom code? ChatGPT can generate computer code in various languages, including JavaScript, Python, R, or Excel macro code and formulas. If the code has errors or needs revision, simply provide feedback, and ChatGPT will help refine it.

7. Analyzing Data for Informed Decisions

Generative AI excels at analyzing financial data to detect anomalies in trends, amounts, or percentage changes that require deeper investigation. This insightful information directly supports better decision-making.

For example, a financial analysis powered by ChatGPT might reveal opportunities for operational improvements, leading to significant cost reductions and improved profitability. Tipalti’s Ask Tipalti AI, for instance, provides real-time financial data insights and spend analysis.

8. Research for Business Plans and Pitch Decks

Preparing a business plan or pitch deck demands extensive research. ChatGPT can perform preliminary research, helping you brainstorm ideas and generate text or images. Always fact-check the information and provide up-to-date inputs for the best results.

9. Creating Preliminary Financial Forecasts and Budgets

Generative AI can assist in making preliminary demand predictions, financial forecasts, and budgets. While not accurate enough to stand alone, it provides a solid starting point that you can refine with your expert judgment and additional information.

10. Supporting Audit Processes

In external audits, analytical reviews help identify anomalies in financial data. ChatGPT can act as an auditing aid by analyzing financial data. As audit automation programs increasingly incorporate ChatGPT via API connections, its role in public accounting firms will become even more prominent.

11. Conducting Tax and Legislation Compliance Research

While not yet ready to prepare accurate tax returns, ChatGPT is a valuable tool for tax research. You can use it to summarize new or existing legislation, such as tax laws. For current information, utilize ChatGPT’s ‘Search’ feature or provide PDF documents with the legislative content.

12. Enhancing Business Communications and Brainstorming

ChatGPT is excellent for brainstorming ideas and drafting emails, reports, and other business communications. You can provide prompts specifying your desired writing style, context, and tone. Always review and revise the suggested content for accuracy and clarity.
