AI application in procure to pay

With the unprecedented pace of the AI evolution, CFOs are looking to use Generative AI (GenAI) in particular to improve process efficiency, reduce costs and mitigate risks for the finance function. A critical challenge, however, is identifying the right approach and process to begin this transformation. While GenAI has applications across finance processes, the technology has matured significantly for P2P process, supporting end-to-end automation of tasks, enhanced decision-making and optimised costs and workflow.

P2P landscape and AI/GenAI application

Traditional P2P processes can present challenges due to:

  • disintegrated data across systems;
  • lack of end-to-end automation;
  • limited visibility for internal and external stakeholders; and
  • compliance risks, which hinder efficiency and increase functional costs.

AI tools can help streamline the end-to-end P2P process using machine learning (ML), natural language processing (NLP), optical character recognition (OCR), virtual assistants and AI-powered contract management tools.

Procure to Pay

Vendor Management:

  • Vendor On-Boarding: Gen AI can help streamline the vendor assessment and on-boarding process by providing comprehensive analysis of suppliers across multiple parameters and automating data-entry to ensure supplier creation in ERP and mitigating risks of bias and manual errors in the process.

  • Vendor Evaluation: Gen AI can define parameters for vendor evaluation and periodically flash performance reports collating information from disparate sources against identified leading to objectivity and transparency in the overall evaluation process. 

  • Query Management: Virtual assistants can independently manage vendor queries across the P2P life-cycle including addressing queries on company policies, tender status or their payment status leading to overall reduced costs and enhanced process efficiency.

Order Management

  • Demand Forecasting: Gen AI can analyse massive datasets of procurement history and support defining the economic order quantity and overall contract value to optimise vendor negotiation process. There are Out of the box (“OOTB”) capabilities offered by standard financial analytical tools for forecasting and simulations, which can be significantly leveraged by teams with the right training. 
  • Purchase: Gen AI and Virtual bots can help simplify and automate processes for raising Purchase Requisition, defining and release of RFQs to suppliers and release of Purchase Order enabling risk management and assisting procurement team to focus on strategic initiatives and complex negotiations.
  • Contract Management: Gen AI enabled contract management platforms can generate draft contracts, review contracts to identify potential risks, help define critical KPIs/SLAs, monitor performance obligations and analyse performance data to identify opportunities for contract optimisation.Most of these platforms have seamless integration capabilities across CRMs, ERPs and collaboration tools; significantly reducing the effort in monitoring contract compliance and improving overall process efficiency.  

Inventory Management

  • Predictive Analytics: ML based AI models can calculate the optimal inventory levels for each item, considering variable factors like lead times, consumption and safety stock requirements.

Invoice Processing

  • Invoice Extraction and Accounting: Historically organisations used OCR based Bots to automate the invoice extraction process. However, it involved significant time and effort in training Bot. had it’s limitations in operational terms for managing unstructured data, data accuracy leading to constant development and training. Gen AI based tools have been trained over significant data and formats, leading to largely “plug & play” deployment. Gen AI tools can integrate seamlessly across ERPs and applications enabling overall extractions, processing and accounting to be truly touchless, allowing teams to focus on exception management. 
  • Helpdesk Leveraging NLP and ML, Virtual assistants can update on invoice status, approval and payment schedules to internal and external stakeholders leading to reduced operational costs and faster resolution.

Analytics

  • Spend Analytics: AI tools can be leveraged to provide insights on overall cost drivers, supplier performance and cash-flow for strategic decision making. 

Procure to Pay

  • Vendor onboarding: AI can streamline the vendor assessment and on-boarding process. It does this by providing independent, comprehensive analysis of the accuracy of information provided by suppliers across multiple parameters and by automating data-entry in enterprise resource planning (ERP). This mitigates risks of fraud, bias and manual errors in the process.
  • Vendor evaluation: AI can define parameters for vendor evaluation, monitor them and generate periodic flash performance reports collating information from disparate sources. This creates objectivity and transparency in the overall evaluation process.
  • Query management: Virtual assistants can independently manage vendor queries across the P2P life cycle. This includes addressing queries on company policies, tender status or their payment status leading to enhanced process efficiency and overall cost reduction.

  • Purchase: AI and virtual bots can simplify and automate processes for raising purchase requisitions, defining and releasing requests for quotation (RFQs) to suppliers and releasing purchase orders. This enables risk management and assisting procurement teams to focus on strategic initiatives and complex negotiations.
  • Contract management: AI-enabled contract management platforms can generate draft contracts and review them for potential risks. They can help define critical key performance indicators (KPIs) and service level agreements (SLAs), monitor performance obligations and analyse performance data to identify opportunities for contract optimisation.

Most of these platforms have seamless integration capabilities across customer relationship management (CRM) platforms, ERP and collaboration tools. This significantly reduces the effort in monitoring contract compliance and improves overall process efficiency. 

AI in inventory management using predictive analytics offers several benefits and functionalities including:

  • Forecasting: AI-enabled platforms leverage ML and historical data to provide real-time insights into trends, demands fluctuations and seasonality, enhancing supply chain visibility and improving inventory accuracy.
  • Cost optimisation: AI enables data-driven decision making by continuous refinement of predictive models through feedback loops to reduce fulfillment, storage, handling and transportation costs and improve resource allocation.

  • Invoice extraction and accounting: Historically, organisations used optical character recognition (OCR)-based bots to automate the invoice extraction process. That involved significant time and effort in training bots, however, and had operational limitations for managing unstructured data and data accuracy. This meant constant development and training. AI models have been trained over substantial number of invoices across a range of formats, leading to largely ‘plug and play’ deployment. They enable automated extraction, processing and accounting of invoices; improving process efficiency and reducing risks of compliance and incorrect payment.
  • Helpdesk: By leveraging NLP and ML, virtual assistants can update internal and external stakeholders on invoice status, approval and payment schedules. This leads to reduced operational costs and faster resolution. 

Spend analytics involves the aggregation and classification of spend data from multiple sources to identify opportunities for cost reduction and performance improvement. AI tools can significantly assist with:

  • Automated data categorisation: AI tools can clean and categorise vast amounts of data from various sources, eliminating manual effort and ensuring data accuracy for internal reporting.
  • Pattern recognition and anomaly detection: AI algorithms can help identify patterns and anomalies across large sets of data, enabling enhanced risk management.
  • Predictive analytics: By leveraging real-time data with historical spend data, AI-powered tools enable proactive budget management, forecasting future spending and uncovering potential cost savings to enable strategic decision-making.

Key actions businesses can take today

As technology and solutions evolve, finance functions are evaluating where to begin with AI and GenAI in particular. The P2P process is where you can start small and simple, experiment at pace, and foster creativity and curiosity. Our survey in association with ACCA and Chartered Accountants ANZ showed 60% of CFOs were considering deploying AI for P2P in the next three to five years.

As organisations embark on their AI journey in P2P, it’s important to consider:

  • The transformation landscape: Organisations should ensure all AI tools and platforms they are evaluating for implementation can seamlessly integrate with their technology architecture and overall transformation landscape.
  • Data security and governance policy: Organisations should review their data security and governance policies considering the AI playbook. Each organisation’s data policy could significantly influence the evaluation of AI platforms. Some platforms, for example, might only be available in cloud environments while their organisation policy may dictate their preference for in-house stack.
  • Global operations: Organisations with global operations that need localised support across multiple languages should critically evaluate the AI models being considered for deployment to ensure seamless adoption and integration across the operating units.
  • The deployment approach: Organisations should critically assess processes for AI implementation to ensure that they will derive tangible value and a return on their transformation investment.

While the underlying technology is available for a complete suite of P2P processes, organisations may consider modular deployment, deploying relevant and specific use cases.
