Project Overview: ProcureAI – n8n Accounts Payable Vision OCR & 3-Way PO/GRN/Invoice Matching
ProcureAI is an intelligent accounts payable and construction procurement pipeline built on n8n for contracting and manufacturing enterprises managing hundreds of daily supplier deliveries.
The Business Challenge & Technical Requirements
Construction subcontractors and material vendors submit invoices in diverse formats—scanned Arabic paper bills, multi-page PDFs, and WhatsApp photos. Finance teams spent days manually cross-checking every line item against the original Purchase Order (PO) and the site engineer’s Goods Received Note (GRN).

Technical Architecture & Full-Stack Implementation
Cynsera engineered an n8n workflow that monitors the AP inbox and WhatsApp channel, preprocesses images, extracts structured line items via a multimodal Vision LLM with strict JSON schema enforcement, queries PostgreSQL for the matching PO and GRN records, verifies that quantity and unit-price variances fall within a 1.5% tolerance, and either auto-posts the payable voucher or routes exceptions to the project manager.
Key Outcomes & Measurable Impact
Achieved 99.2% bilingual extraction accuracy, eliminated 85% of manual AP data entry, and audited each supplier invoice in under 12 seconds.
