This article will take the procure-to-pay (P2P) process at the core of enterprises as an example to illustrate how AI is gradually integrated into ERP, from discovering demand to creating value.
ERP systems are like enterprise stewards, responsible for the management of funds, materials and personnel, but in the face of massive data, changing markets and complex processes, there are practical problems such as low efficiency, easy to make mistakes, and relying on experience for decision-making. The addition of AI can inject new vitality into it, but the integration of the two is not a simple superposition, it must start from the business pain points, and the core of the integration is data-driven, model decision-making, and process automation.
1. Tap the value of AI from business pain points
Many enterprises fall into the misunderstanding of technology first in the practice of AI+ERP and invest a lot of resources to develop large models, but with little effect. Effective integration begins with the deep deconstruction of business processes, establishing a closed-loop logic of “business pain points→ process disassembly→ and AI function mapping”.
Demand mining starts with process visualization and pain point quantification
For example, an auto parts company used BPMN (Business Process Model and Labeling) tools to draw a P2P full flow chart containing 12 key nodes through management interviews and front-line personnel scenario restoration. The analysis found that the procurement department handled an average of 200+ demand orders per day, of which 30% needed to be reworked due to vague material specifications; The average time for supplier sourcing is 14 days, far exceeding the industry benchmark of 8 days. The company uses the “influence × frequency” matrix to evaluate the priority of pain points, and finally locks in “low supplier sourcing efficiency” (influence 9/10, frequency 8/10) and “high error rate of three-order matching” (influence 8/10, frequency 9/10) as the core improvement goals.
Three-layer architecture for technical adaptation
Data Layer:It is not enough for the data layer to rely only on static data (materials, supplier master data) within ERP; It is necessary to integrate internal and external multi-source heterogeneous data through ETL/API to build a unified data view and provide high-quality input for model training and real-time decision-making.
B-end product manager’s ability model and learning improvement
The first challenge faced by B-end product managers is how to correctly analyze and diagnose business problems. This is also the most difficult part, product design knowledge is basically not helpful for this part of the work, if you want to do a good job in business analysis and diagnosis, you must have a solid …

Algorithm layer:Select the model that matches the business scenario.
- Handle invoices and fuzzy descriptions: OCR (Optical Character Recognition) is responsible for extracting text from images/PDFs, and NLP (Natural Language Processing) is responsible for semantic understanding (e.g., parsing “about 500 pieces” into a reasonable interval of “450-550 pieces”). (Principle: OCR recognizes characters based on CNN and other models; NLP uses part-of-speech annotation, dependent syntactic analysis, and entity recognition to understand context).
- Forecasting inventory demand: LSTM (Long Short-Term Memory Network) models excel at capturing long-term dependencies (such as seasonal fluctuations) in time series. (Principle: LSTM’s gating structure effectively learns long-term patterns).
Application layer:Design practical and scalable solutions. For example, an intelligent reconciliation system developed by a group supports loosely coupled integration with mainstream ERPs such as SAP and Oracle (usually through API gateways or middleware), and allows business personnel to configure reconciliation rules through low-code platforms. (Principle: The low-code platform provides visual interfaces and pre-built components to lower the technical threshold).
2. AI-driven P2P full-chain scenarios
The P2P process involves key links such as demand planning, sourcing, contracts, logistics, reconciliation, and payment, and AI technology can effectively solve the pain points of each link.
Demand planning and sourcing
Pain point: The vague description of material requirements leads to mismining; Low supplier screening efficiency and incomplete information bring risks.
AI Solutions: From Empiricism to Data-Driven
- Intelligent Demand Generation:Based on the Transformer model, it learns from historical procurement data to automatically complete material specifications and parameters, and predicts the proposed purchase quantity based on the production plan. (Principle: The model learns material attributes, purchase volume, and production planning characteristics to make predictions).
- Intelligent supplier sourcing:Build a supplier knowledge graph and integrate multi-dimensional data such as certification, performance records, and risk information. (Principle: Construct an entity relationship network based on graph database, vectorization using embedding technology). The cosine similarity algorithm is used to match the optimal supplier. (Principle: Calculate the similarity between the query vector and the vendor feature vector).
- Smart price comparison and negotiation:Access real-time market data, combine with suppliers’ historical quotations, and use game theory algorithms (such as the Nash equilibrium solver) to generate optimal bargaining strategies. (Principle: Simulate multiple rounds of strategy interaction and predict the other party’s reaction).
Contract signing and execution
Pain point: Disputes arise due to vague contract terms; Delays in fulfillment nodes affect production.
AI Solution: Automated Review and Proactive Warning
- Smart Contract Review:Based on the large model based on RAG (retrieval augmented generation) + BGE (text embedding) + MoE (expert hybrid) architecture, it automatically identifies risk points such as “acceptance criteria are not quantified” and “rights and responsibilities are not equal”. (Principle: RAG accurately retrieves relevant terms, BGE calculates text similarity, and MoE comprehensively judges risks).
- Intelligent Performance Monitoring:NLP is used to parse the key nodes of the contract (entity identification and relationship extraction), and the time series model is constructed with ERP order data for deviation warning. (Principle: The model learns historical performance data to predict the completion time and sets a threshold alarm).
Order collaboration and logistics tracking
Pain point:Order change information is out of sync, leading to supply chain disconnection; Logistics abnormalities cause cargo damage.
AI solution: real-time linkage and dynamic optimization
- End-to-end collaboration:Leverage RPA (Robotic Process Automation) to synchronize order change information to the supplier portal in real time. (Principle: RPA automatically captures, fills, and transmits information between systems).
- Intelligent logistics scheduling:Integrate GPS, meteorology, and traffic data, and apply reinforcement learning algorithms to dynamically plan optimal routes. (Principle: RL agents learn to maximize the action strategy of “on-time delivery + lowest cost” in a simulated environment).
Invoice processing and reconciliation
Pain point:the workload of three orders matching is large and the error rate is high; Variance analysis is time-consuming and labor-intensive.
AI Solution: Automation and Intelligence
- Multimodal invoice identification and matching:OCR extracts information with high precision (99.7%), and NLP understands semantics (such as “discounted price”) and automatically matches three orders. (Principle: CV+OCR+NLP combination, rule engine or model for field matching).
- Intelligent Variance Analysis:Apply machine learning classification models (e.g., XGBoost, random forest) to automatically identify the reasons for discrepancies (e.g., price mismatch due to promotion, quantity difference due to loss). (Principle: The model learns historical discrepancies to predict the root causes).
Payment & Vendor Management
Pain point:Rigid payment strategies miss out on discounts; Supplier evaluation is highly subjective.
AI solution: pay equal attention to efficiency and risk control
- Dynamic Payment Optimization:Based on the supplier’s credit rating and enterprise cash flow forecast, the linear programming (LinearProgrammingLP) algorithm is used to generate the optimal payment plan. (Principle: Construct an objective function to solve the optimal payment time combination under constraints).
- Supplier Health Assessment:Establish a multi-indicator weighted scorecard model (such as 40% on-time delivery rate, 30% quality pass rate, etc.) and automatically generate graded reports. (Principle: Quantitatively evaluate supplier performance).
Compliance & Audit
Pain point:Low efficiency in manual monitoring of compliance risks (such as over-budget procurement and related party transactions); Hidden fraud is difficult to detect.
AI Solution: Intelligent Monitoring and Risk Insight
- Real-Time Compliance Monitoring:Build a knowledge graph to associate order, payment, and supplier relationship data, and set up a rule engine to scan for exceptions. (Principle: Build an entity relationship network and scan abnormal patterns in real time).
- Intelligent audit analysis:Apply correlation rule algorithms (e.g., Apriori) to mine anomalous patterns (e.g., unusual high-frequency combinations) in transaction data. (Principle: mining frequent item sets and strong association rules).
3. Intelligent upgrade landing path
The successful implementation of AI+ERP needs to follow a scientific path:
- Consolidate the data foundation: For example, an automobile group faced problems such as 30% of supplier information missing and 5% of invoice images blurring leading to OCR failure in the early stages of the project. By establishing data standards, master data management and cleaning processes, and setting up quality boards such as “supplier information completeness rate” and “image clarity rate” to continuously track data, data quality has been significantly improved within half a year. In addition, sensitive data is encrypted with the national secret SM4 algorithm (principle: symmetric encryption ensures security).
- Focus on value pilots: Choose scenarios with clear pain points and quick results to start. For example, first use “invoice processing” as a pilot to develop the MVP version for A/B testing (AI group: 2 minutes/order, error rate 0.5% vs manual group: 25 minutes/order, error rate 8%), and the effect is significant before it can be promoted quickly.
- Continuous iterative optimization:Establish a model monitoring dashboard to track key business indicators (KPIs) and model performance indicators (such as accuracy, recall, and data drift), and gradually iterate trial and error upgrades by introducing more advanced model algorithms or supplementary data.
4. Rationally view the risks of intelligence
- Data bias:A company has a geographical bias in the recommendation results due to the high proportion of southern suppliers in the training data. (Principle: Uneven data distribution leads to model bias). Solved by data rebalancing and regular monitoring of data distribution.
- Algorithm Black Box:Use techniques such as SHAP values to improve model interpretability, such as demonstrating key rationale when referring to suppliers (e.g., “98% on-time”).
- System dependencies:The API gateway is used to realize the low-coupling integration of AI modules and ERP (microservice architecture), and high-availability solutions (redundancy and disaster recovery) are designed to ensure that core services are not interrupted.
