Automating Three-Way Matching and Accounts Payable Processing with AI on AWS
Learn how a leading real estate developer partnered with 1CloudHub and AWS to automate purchase order, goods receipt, and invoice reconciliation using AI-powered document intelligence, reducing processing time, improving accuracy, and accelerating vendor payments.
Benefits
~70% reduction in RFP and APV preparation effort
85% of document sets processed automatically without manual intervention
Automated three-way matching across PO, GRN, and Invoice documents
Overview
The customer is one of the Philippines’ leading real estate development organizations, managing a diverse portfolio of residential, commercial, and mixed-use developments.
Operating across multiple business entities and handling a high volume of procurement transactions, the organization works with a large ecosystem of vendors, contractors, brokers, and partners. Managing procurement and payment workflows efficiently while maintaining financial controls had become increasingly critical to supporting business growth and operational excellence.
The Challenge
Accounts payable and procurement teams relied heavily on manual document validation and reconciliation processes.
For every payment request, staff were required to manually compare Purchase Orders (POs), Goods Receipt Notes (GRNs), and Supplier Invoices to verify quantities, pricing, and fulfillment status before approving payments.
The process was labor-intensive, time-consuming, and vulnerable to human error.
Additional challenges included:
🔹Manual comparison of PO, GRN, and Invoice documents
🔹High transaction volumes across multiple vendors and projects
🔹No automated extraction or validation of procurement documents
🔹Limited visibility into processing status and bottlenecks
🔹Manual preparation of Request for Payment (RFP) and Accounts Payable Voucher (APV) forms
🔹Difficulty identifying mismatches and exceptions quickly
🔹Lack of a centralized audit trail across document workflows
🔹Delayed payment cycles impacting vendor experience
The organization required an intelligent automation platform capable of streamlining accounts payable operations while maintaining accuracy, governance, and compliance.
The Solution
1CloudHub partnered with the customer to design and implement an AI-powered three-way matching and disbursement automation platform on AWS.
The solution combines document intelligence, OCR, Generative AI validation, workflow automation, and real-time monitoring to automate the entire reconciliation process from document submission through payment preparation.
The platform enables procurement, materials management, and accounts payable teams to process transactions significantly faster while improving accuracy and transparency.
Intelligent Document Ingestion and Extraction
The platform provides a secure centralized channel for document submission and processing.
Purchase Orders, Goods Receipt Notes, and Supplier Invoices are uploaded and securely stored within AWS.
Using Amazon Textract, the solution automatically extracts:
- Header information
- Vendor details
- Invoice references
- Line-item data
- Quantities
- Pricing information
- Tax details
- Transaction dates
The extracted information is normalized into a unified schema, creating a consistent foundation for downstream validation and matching processes.
AI-Powered Three-Way Matching
Once document data is extracted, Amazon Bedrock validates and standardizes information across all documents involved in the transaction.
The AI engine intelligently resolves common challenges such as:
Vendor Name Variations
Different naming conventions across documents are automatically identified and normalized.
Item Code Discrepancies
The system recognizes equivalent item descriptions and coding formats across procurement documents.
Numeric and Currency Standardization
Amounts are normalized into a consistent format regardless of source document formatting variations.
Data Validation
Extracted information is validated and scored before entering the matching workflow.
This allows the platform to perform highly accurate PO-GRN-Invoice matching while reducing false exceptions.
Advanced Document Intelligence for Real-World Scenarios
Unlike traditional rule-based matching systems, the platform was designed to handle complex procurement workflows commonly encountered in enterprise environments.
Split-Value Invoice Processing
The AI engine automatically aggregates invoice values spread across multiple line items and formats before validation.
Numeric Format Normalization
Regional currency and decimal formatting differences are standardized automatically to ensure accurate comparisons.
Low-Quality Document Detection
A built-in quality assessment layer detects unreadable or low-resolution files and routes them for resubmission before processing.
Multi-GRN Matching
The system supports scenarios where a single Purchase Order is fulfilled through multiple deliveries and Goods Receipt Notes, ensuring accurate matching against consolidated supplier invoices.
These capabilities significantly reduce manual intervention while maintaining high validation accuracy.
Automated Exception Management
When discrepancies are identified, the platform automatically generates structured exception alerts and routes them to the appropriate teams for review.
Instead of manually reviewing every transaction, teams only need to focus on genuine mismatches requiring attention.
This exception-based processing model enables faster throughput while improving operational efficiency.
Automated RFP and APV Generation
For successfully validated transactions, the platform automatically generates key payment documentation.
Request for Payment (RFP)
Required procurement and payment information is automatically populated into RFP templates.
Accounts Payable Voucher (APV)
Accounts payable forms are generated with key transaction data already completed.
By eliminating repetitive data entry, teams can focus only on review and approval activities that require human judgment.
Visibility, Governance, and Auditability
The solution was designed with strong operational governance and financial control requirements in mind.
Every transaction records:
- Source documents
- Extracted data
- Validation outcomes
- Matching decisions
- Exception logs
- User activities
- Workflow status updates
Real-time dashboards provide management teams with visibility into:
- Processing volumes
- Match success rates
- Exception trends
- Workflow bottlenecks
- Operational performance
Comprehensive monitoring and audit trails support compliance, accountability, and process transparency.
AWS Services Used
The solution was built using a scalable cloud-native architecture powered by AWS services including:
- AWS Amplify
- Amazon Cognito
- Amazon API Gateway
- AWS Lambda
- Amazon Textract
- Amazon Bedrock
- Amazon S3
- Amazon EventBridge
- Amazon SES
- Amazon RDS
- Amazon CloudWatch
- Amazon VPC
Together, these services provide secure document processing, AI-powered validation, workflow automation, monitoring, and enterprise-grade scalability.
Outcome & Business Impact
The implementation delivered substantial improvements across procurement and finance operations.
Accelerated AP Processing
End-to-end accounts payable processing time was reduced by approximately 80%, transforming manual reconciliation workflows into automated validation processes completed in minutes.
Faster Payment Documentation
Preparation time for Request for Payment and Accounts Payable Voucher forms was reduced by approximately 70%, eliminating repetitive manual data entry.
Increased Automation
More than 85% of document sets are now processed and validated automatically without human intervention, compared to a fully manual process prior to implementation.
Improved Accuracy and Control
Automated validation and exception detection significantly reduced processing errors while strengthening compliance and auditability.
Enhanced Vendor Experience
Faster reconciliation and payment workflows improved transaction visibility and accelerated payment processing for suppliers and partners.
