Contractor Business OS – Estimating, Quote & Job Costing Excel Spreadsheet

Stop guessing whether your jobs are actually profitable.

Contractor Business OS is a complete contractor estimating, quoting and job costing spreadsheet designed to help contractors manage the financial side of a job from the first estimate through final payment.

Instead of juggling separate estimate templates, expense sheets, change-order files, invoices and profit calculations, you get one connected Excel system built around the real contractor workflow:

Estimate → Quote → Job Budget → Purchase Orders → Actual Costs → Change Orders → Progress Billing → Payments → Final Profit

Whether you are a general contractor, remodeler, electrician, plumber, painter, landscaper, carpenter, flooring contractor, HVAC contractor or other trade professional, the workbook gives you a structured way to price work and monitor where your money is going.

Build Better Estimates

Create detailed estimates using quantities, unit costs, labor, materials, equipment, subcontractors and other project costs.

The system helps you calculate:

• Direct project costs
• Labor costs
• Material costs
• Equipment costs
• Subcontractor costs
• Other job expenses
• Markup
• Target margin
• Contingency
• Tax
• Estimated profit
• Final customer price

Use the reusable price book to save commonly used items and reduce repetitive estimating work.

Create Professional Contractor Quotes

Turn your estimate information into a clean client-facing quote that can be printed or saved as a PDF.

Keep internal costing information separate while presenting customers with a professional document containing the project information, scope, pricing and acceptance details they actually need.

Know What Every Job Is Costing You

Winning a job does not automatically mean making money.

Track actual project costs across:

• Materials
• Labor
• Equipment
• Vehicles
• Subcontractors
• Miscellaneous expenses

Compare those costs with your original budget so you can see where a project is over or under budget.

Track Committed Costs Before the Bills Arrive

Purchase orders and subcontractor commitments can affect profitability before money actually leaves your account.

Contractor Business OS helps you separate:

Budgeted Costs

Actual Costs

Committed Costs

Remaining Costs

Forecast Final Costs

This gives you a much clearer picture of where a job is heading instead of only showing what has already happened.

Forecast Final Job Profit

See more than historical expenses.

The system helps you monitor:

• Original contract value
• Approved change orders
• Revised contract value
• Estimated job cost
• Actual cost to date
• Committed costs
• Forecast final cost
• Estimated profit
• Current profit
• Projected final profit
• Gross margin
• Cost variance

Use the Job Overview and dashboard to identify potential overruns while you still have time to act.

Manage Change Orders

Keep additional work separate from the original contract instead of losing track of changes in emails, notes or conversations.

Track:

• Change order number
• Description
• Requested amount
• Cost
• Customer price
• Status
• Approval
• Approval date
• Related job
• Profit impact

Approved change orders can be reflected in the revised job value so you can see the updated financial position of the project.

Track Purchase Orders & Vendors

Record project commitments and purchase orders so you can see what has already been ordered or committed.

Track information such as:

• PO number
• Job
• Vendor
• Description
• Quantity
• Cost
• Expected delivery
• Received status
• Payment status
• Notes

This makes it easier to understand future project costs before invoices arrive.

Track Labor Properly

Labor can destroy a job's margin when estimated hours and real hours drift apart.

Track:

• Employee or worker
• Regular hours
• Overtime
• Labor rates
• Labor cost
• Estimated hours
• Actual hours
• Labor variance

The included labor-rate calculator can also help you work toward a more realistic billable rate rather than pricing labor based only on hourly wages.

Handle Progress Billing

For projects that are not billed in one payment, use the system to monitor progress billing and payment schedules.

Track:

• Contract value
• Deposit
• Progress invoices
• Amount billed
• Amount received
• Retainage
• Outstanding balance
• Remaining contract value

A Schedule of Values worksheet is also included for projects where billing needs to be broken down by project phase or work item.

Track Invoices & Payments

Keep an organized record of customer invoices and incoming payments.

Monitor:

• Invoice number
• Invoice date
• Customer
• Job
• Invoice amount
• Tax
• Retainage
• Amount paid
• Outstanding balance
• Payment status
• Payment date

Quickly identify unpaid balances instead of searching through separate spreadsheets or paperwork.
