Accounts payable automation in construction: a key performance lever for contractors in Canada and Ontario

AP automation construction

The construction industry including civil engineering, major works and general contracting is characterised by complex and voluminous document management. Purchase orders, supplier invoices, subcontracting contracts, progressive payment schedules, SEAO tenders, 10% retainage, CCQ and RBQ attestations: each construction site generates hundreds of administrative documents to validate and file. Accounts payable automation has become a strategic necessity for Canadian construction firms.

Preconfigured construction workflows

Viridem ships preconfigured workflows built for jobsite reality, covering the full AP cycle: automated PO management per site/phase/cost-centre, multi-level invoice validation, automatic 10% retainage calculation, CCQ/RBQ/CNESST attestation checks, and native integration with Sage 300 CRE, Maestro, Vision Construction, Avantage, Acomba, Procore and Acumatica Construction.

Proprietary technology enriched by AI

Viridem's OCR + AI technology has been deployed and improved in construction since 2013. 80% of standard documents are processed by our classic engine; the remaining 20% (non-standard formats, handwritten subcontractor invoices) trigger our generative-AI assist layer. AI can be toggled on/off at any time.
