Frequently asked questions
What is contractor estimating and change order software?
It is software that helps specialty contractors build versioned estimates, document and approve change orders, track live job margin, and invoice from approved work. WorkGrid Pro focuses on that workflow—without payroll, ERP modules, or spreadsheet chaos.
Who is WorkGrid Pro for?
Remodelers, painters, flooring installers, roofers, HVAC, electrical, plumbing, and specialty subcontractors who outgrew spreadsheets but do not want a full ERP. If your pain is estimate revisions, change-order approvals, and margin, you are the audience.
How do estimate versions protect contractor margin?
Sent estimate versions stay locked. Revisions create a new version instead of overwriting the old quote. That audit trail proves what was offered, reduces disputes, and gives change orders a clear baseline so extras do not become unpaid work.
How much does WorkGrid Pro cost?
Plans start at $29/month for estimates, change orders, and basic invoices. Growth, Pro, and Business add job costing, scheduling, mobile field tools, and team features.
