Construction APIs that connect your project management, accounting, and field operations into one data layer.
We build API integrations for construction companies — Procore and Buildertrend integrations, accounting system connectivity, subcontractor data exchange, document management APIs, and the data pipelines that keep your project data accurate without manual sync. Fixed scope, fixed price.
Project data lives in Procore. Financial data lives in Sage 300 or QuickBooks. Field data is in email and spreadsheets. Getting a real picture of where a project stands requires pulling data from three places and doing math in a spreadsheet.
Construction project data is distributed across more systems than almost any other industry. A general contractor managing 10 active projects simultaneously operates project data in Procore or Buildertrend (schedules, RFIs, submittals, change orders), financial data in Sage 300 CRE or QuickBooks (job costing, AP, AR, committed costs), field data in daily reports, photos, and safety inspection apps, and subcontractor data in subcontract management tools or email.
The project manager's job includes a significant amount of data reconciliation work that has nothing to do with managing the project — pulling the job cost report from accounting, comparing it to the budgeted cost in Procore, identifying where the variance is, and figuring out if a change order is needed. That reconciliation takes time that should be spent on the project, and it's only as accurate as the last manual sync between systems.
The highest-value integration for most construction companies is the one between Procore and the accounting system. Approved change orders in Procore should automatically create contract modifications in the accounting system. Approved invoices in accounting should update the cost data in Procore. Subcontractor certifications and insurance from Procore should be visible in the AP workflow. These two-system syncs eliminate the majority of manual data reconciliation.
A construction API integration layer that connects your project management system, accounting software, and field reporting tools — with a unified project data view that doesn't require manual reconciliation to produce.
Procore API integration
Procore REST API integration for project, budget, change order, RFI, submittal, and daily log data. Budget snapshots synced to the financial system. Approved change orders pushed to accounting as contract modifications. RFI and submittal status accessible in the project reporting layer without logging into Procore.
Buildertrend integration
Buildertrend API integration for residential construction — project schedule, selections, change orders, and client communication data. Budget and actual cost sync to accounting.
Accounting system connectivity
Sage 300 CRE, Vista by Viewpoint, or QuickBooks integration for job cost sync — committed costs (subcontracts, POs), actual costs (AP invoice approvals), and contract values (owner contracts + change orders). Real-time job cost position without manual reconciliation.
Subcontractor compliance management
Subcontractor insurance certificate tracking with expiration alerts. Lien waiver collection workflow. Subcontractor payment status from accounting visible in the project management system.
Field reporting data pipeline
Daily field report data from Fieldwire, Raken, or custom-built field apps aggregated into the project reporting layer — labor hours, equipment hours, quantities installed. Comparison to budgeted quantities for progress percentage calculations. Built on Next.js API routes, Postgres, Procore REST API, Buildertrend API, and accounting system REST or CSV-based integrations.

Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
Construction companies evaluate technology investments against project overhead cost. If an integration reduces the project manager's data reconciliation time by 5 hours per week across 10 active projects, the ROI calculation is direct. Fixed scope, fixed price.

Yes — Procore's ERP integrations require the ERP Integration module in your Procore subscription. Some integrations (Sage 300 CRE, Vista) have Procore-certified connectors available. Custom API integrations using Procore's REST API require the Procore API access, which is included in Enterprise tier subscriptions.
Subcontractor data exchange happens through structured data exchange (email confirmations, subcontractor portals, or Procore's subcontractor access features) rather than direct system integration. The integration layer standardises subcontractor data from these sources into the GC's system of record.
Multi-entity job costing with cost allocation between JV partners requires custom handling in the accounting integration — the split logic, allocation percentages, and entity-specific reporting are scoped as specific integration requirements based on your JV structure.
Procore integration, accounting system connectivity, and field data pipeline typically runs $35k–$70k. Custom accounting system integrations and multi-company structures are the main scope variables. Fixed-price.
