Frequently Asked Questions
How does AI handle complex three-way matching when EPC invoices include split shipments and variable freight charges?
Advanced AI models utilize intelligent document processing and natural language understanding to ingest multi-page invoices, line-item purchase orders, and bill of lading documents simultaneously. The system dynamically calculates prorated freight, handles split shipments across multiple delivery dates, and automatically reconciles minor price variances against pre-configured tolerance thresholds, routing only genuine anomalies to human approvers.
What is the typical implementation timeline for procurement workflow automation with Kresto Labs?
A standard enterprise deployment across an EPC organization typically spans 12 to 16 weeks. This timeline includes initial workflow discovery, legacy ERP integration, AI model training on historical procurement data, rigorous testing, and comprehensive user training to ensure seamless adoption across engineering, procurement, and finance teams.
Can AI procurement workflows integrate with legacy ERP systems like SAP, Oracle, or custom databases?
Yes. Kresto Labs designs non-destructive middleware integration layers that connect securely with legacy enterprise resource planning systems, project management software, and document repositories via robust APIs and secure connectors, ensuring data flows bi-directionally without requiring costly or disruptive core system replacements.
How does automated vendor onboarding ensure compliance with international safety and regulatory standards?
Automated onboarding workflows instantly ingest vendor-submitted documentation—such as ISO certifications, safety records, insurance certificates, and tax compliance forms—and cross-reference them against global regulatory databases and corporate compliance rules. The system flags expired credentials or non-compliant records instantly, preventing unqualified vendors from entering the active supplier database.
What specific security measures protect sensitive commercial pricing and supplier contract data during AI processing?
All procurement data processed through Kresto Labs architectures adheres to enterprise-grade security protocols, including end-to-end encryption in transit and at rest, strict role-based access controls, and private-cloud deployment options that ensure proprietary pricing data and commercial contracts are never utilized to train public AI foundation models.
