General contractor software helps GCs coordinate subcontractors, track multi-phase project costs, manage permits and inspections, and bill clients at project milestones from one connected system. When scope changes happen mid-project (a hidden condition in the wall, an owner-directed addition, or a subcontractor delay that changes the schedule), those changes need to be captured, documented, and reflected in the final billing. Without a system built for that level of moving parts, something always falls through at cost to the relationship and the margin.

IRONGRID is general contractor software built around the real demands of multi-trade project management. Use it as your GC software for work order creation, subcontractor coordination, and phase-based job tracking, your general contractor CRM to keep client records and project history organized, and your contractor field management software to keep labor hours and material costs tied to every job. Construction management software that gives your whole team, office and field, a single place to see the truth about every project.

How general contracting businesses use IRONGRID

A commercial tenant buildout kicks off with a signed contract. The project manager opens IRONGRID and creates the work order, breaking the project into phases: demo, framing, MEP rough-ins, insulation, drywall, finish work, and punch list. Each phase is assigned to the responsible party: your framing crew for structural, the electrical sub in the Partners database for the rough-in, the HVAC sub for the mechanical work. Everyone knows their phase, their schedule, and their deliverables before the demo crew shows up.

Through the project, the superintendent logs daily labor hours, tracks materials delivered to the site, and attaches inspection documentation to the work order as each phase passes. The project manager can see cost actuals building against the bid in real time. When the final punch list is complete and the certificate of occupancy is in hand, the office generates the final invoice from the work order with the full project cost breakdown and sends it the same day the job closes.

For GCs with repeat commercial clients (property developers, restaurant groups, retail chains with ongoing buildout programs), IRONGRID keeps every project in a linked client record. When the same developer starts a new location, their contact details, preferred subcontractors, and project history are already in the system. A new work order takes minutes to create and the project history gives you real data on labor rates and material costs to sharpen your next bid.

Frequently asked questions

Common questions about using IRONGRID for general contracting businesses.

Can IRONGRID manage multi-trade GC projects with subcontractors?

Yes. Coordinate subcontractors through the Partners feature, assign them to work orders, and track their progress alongside your own crew across every phase of a project.

How does IRONGRID handle job costing for general contractors?

Build custom cost calculations that factor in labor hours, materials, and subcontractor costs. Track actual costs against each work order to monitor margins in real time.

Can IRONGRID manage large-scale projects with multiple phases?

Yes. Break projects into phases with subtasks covering demolition, framing, rough-ins, inspections, finishes, and punch lists, all tracked from a single work order.

How does IRONGRID help general contractors manage scope changes on active projects?

When the scope changes (an owner-directed addition, unexpected conditions behind a wall, or a subcontractor delivering materials outside the original spec), the project manager logs the additional labor and materials against the work order. Those additions are reflected in the job's cost total in real time, and the final invoice generates from the work order with the full updated scope. A clear activity log documents when and why the change was made.

What is the best software for general contractors?

The best general contractor software connects job creation, subcontractor tracking, phase-based checklists, materials and labor cost tracking, and client invoicing in a single platform your whole team can access from the field or the office. IRONGRID is GC software built for multi-trade project operations, with warehouse inventory, partner management, and analytics included alongside the core field management tools. Unlimited team members on every plan.

Do general contractors need a CRM?

Yes. A general contractor CRM needs to hold project history, bid records, subcontractor relationships, and client communication alongside contact information, and it needs to connect directly to active work orders. When an owner calls about a project from two years ago, you need to pull up that record instantly and see every cost, every subcontractor, and every invoice from that job. IRONGRID keeps all of that organized in one place.

Is there a mobile app for general contractors?

IRONGRID runs as a Progressive Web App on any iOS or Android device. Project managers and superintendents add it to their home screen in under a minute. From the field, they can view work order details, update phase status, attach inspection photos, log materials, and communicate job updates without returning to the office. The office sees every update in real time.

Can IRONGRID handle milestone-based billing for general contracting projects?

Yes. Invoice clients at project milestones (deposit, foundation complete, framing complete, final inspection) by generating invoices from the work order at each stage. Each milestone invoice is tracked separately so you always know what has been billed and what is outstanding. Payments are collected electronically by card or ACH. On Pro and Business plans, you can push each milestone invoice to QuickBooks in one click, keeping your project billing and accounting in sync automatically.
