For many contractors, Sage 100 Contractor provides that foundation. The platform tracks labor, materials, subcontractors, and overhead — all linked to specific jobs and cost codes. Over time, though, many teams discover they need more: deeper reporting, better forecasting, and easier collaboration between finance and project managers.

What Is Job Costing in Sage 100 Contractor?

Job costing in Sage 100 Contractor helps construction companies track every dollar spent on a project.

Instead of lumping costs together, the system assigns them to jobs, phases, and cost codes. This structure creates a detailed view of:

  • Direct costs (labor, materials, equipment, subcontractors)
  • Indirect costs (overhead, insurance, and fees)
  • Committed costs (purchase orders and subcontracts you’ve signed but haven’t fully billed)

📌 Why it matters: Accurate job costing ensures you see whether each project is profitable — and highlights where costs are creeping out of control.

Key Job Costing Features in Sage 100 Contractor

Sage 100 Contractor offers several built‑in tools for job costing, and each plays a key role:

📂 Job Setup & Cost Codes

Jobs can be broken into phases and cost codes, allowing for detailed tracking. For example, site prep can be tracked separately from framing, or labor can be separated from materials.

⏱ Labor Cost Tracking

Because payroll is integrated, labor hours and burden (like taxes and benefits) flow directly into job cost reports — no duplicate entry required.

📑 Purchase Orders & Subcontracts

Every PO and subcontract links to the job and cost code, so you can see committed costs before invoices even arrive.

🧾 Change Order Management

Approved change orders automatically update the job’s budget and are reflected in cost reports, giving you an updated financial picture in real time.

📊 Job Cost Reports

Dozens of reports show costs by job, phase, or cost code — and make it easy to compare budgets to actuals.

How to Use Sage 100 Contractor for Job Costing

Here’s a straightforward workflow for making the most of Sage 100 Contractor’s job costing features:

1️⃣ Set up jobs and cost codes.
Break each project into meaningful phases and categories.

2️⃣ Enter budgets.
Load estimated costs for every cost code — this becomes your baseline for analysis.

3️⃣ Record costs in real time.
Post labor, invoices, and purchase orders promptly so expenses hit the right job and code.

4️⃣ Run job cost reports.
Review job profitability, committed costs, and budget vs. actual comparisons regularly.

5️⃣ Adjust and forecast.
Use those reports to catch overruns early and update projections for the rest of the project.

The Limitations of Sage 100 Contractor Job Costing

Sage 100 Contractor is a strong backbone for job costing — but it isn’t perfect. As companies grow, common pain points emerge:

❌ WIP reporting is cumbersome
Yes, Sage has WIP reports, but they aren’t flexible. Most teams export data into Excel to calculate percentage‑of‑completion and build schedules for bonding.

❌ Budgeting and forecasting are basic
Sage handles historical reporting well, but it doesn’t offer multi‑scenario forecasting, “what‑if” planning, or cash flow projections.

❌ Project manager collaboration is limited
PMs can’t simply log in and update percent complete. Instead, they email updates or fill spreadsheets that finance later consolidates.

❌ No multi‑entity consolidation
If you operate multiple companies, combining job cost data requires lots of Excel work.

❌ Custom reports require Crystal Reports
Any serious customization — even changing columns — often means diving into Crystal Reports or paying a consultant.

Taking Sage 100 Job Costing Further

When Sage 100 Contractor starts to feel restrictive, contractors usually take one of two paths:

🔄 Excel Add‑Ins (Like Liberty Reports)

Liberty Reports connects Sage 100 Contractor to Excel, letting you pull job cost data directly into spreadsheets.

✅ Pro: No more manual exporting — you hit refresh for live data.
❌ Con: You still have to design every WIP schedule, job profitability report, and forecast yourself.

🚀 FP&A Tools (Like PivotXL)

PivotXL goes much further. Like Liberty Reports, it connects to Sage 100 Contractor — but it also adds structure and automation:

✅ Automates WIP reporting — PMs can update % complete directly, and finance rolls up the data instantly.
