The average construction firm uses 10–15 different software applications per project — project management, accounting, scheduling, estimating, safety, BIM. Most don't talk to each other. Field data reaches the office days late. Budget-impacting changes slip through the cracks.
Connect Your StackGeneric integration platforms weren't built for this industry. Here's what they miss.
Construction software spans cloud (Procore, Autodesk Build), hosted on-premise (Viewpoint Vista), and legacy desktop (Sage 300 CRE). Generic iPaaS platforms only handle the cloud tier, leaving the most critical financial systems disconnected.
Cost codes, WBS structures, submittals workflows, AIA billing formats — construction has specialized data models that generic automation tools don't understand. A change order isn't just a form; it cascades through scheduling, accounting, and subcontractor billing.
Daily logs, safety inspections, progress photos, and RFIs are captured in the field but don't flow automatically to project controls and accounting. Manual re-entry introduces errors and delays.
Purpose-built integration infrastructure for construction technology.
Point our AI agent swarm at any construction vendor's API docs. Seven specialized agents analyze endpoints, detect auth, generate OpenAPI specs, map to a canonical project data model, build connectors, validate, and fix issues — automatically.
One API call handles translation between your PM system, accounting ERP, scheduling tool, and field apps. Auth, schema translation, circuit breaking, rate limiting — all handled. Your platform talks to OneHazel; we talk to every vendor.
Projects, cost codes, change orders, submittals, daily logs — normalized into a unified schema. Switch from one PM tool to another without rebuilding your reporting or accounting integrations.
When a change order is approved in Procore, automatically update the budget in Sage, notify the subcontractor, and adjust the schedule. Cross-system automation without custom code.
Connect the tools your teams already use — from field to back office.
The difference between stitching integrations together yourself and having a purpose-built layer.
From project management to accounting to field operations — one integration layer that understands construction.
