From calculating material costs and labor requirements to presenting detailed project proposals, Sunbase helps contractor teams create clear, professional proposals that improve customer confidence and speed up project approvals.
Solar Proposal Software
Solar companies must present solar system designs, panel layouts, energy production estimates, and installation costs clearly to homeowners. Sunbase solar proposal software helps solar installers generate professional proposals that combine PV system design, shading analysis, energy production modeling, and project pricing in one presentation.
Instead of using multiple tools for solar design, proposal generation, and customer presentations, Sunbase allows solar teams to create complete solar proposals that include system layouts, equipment specifications, financial projections, and installation timelines.
Solar sales teams can quickly move from solar site assessment and system design to customer-ready proposals, helping close deals faster while ensuring accurate system sizing and cost estimates.
Key capabilities include
• Solar panel layout and system design visualization
• Energy production estimates and system performance projections
• Equipment configuration including modules, inverters, and mounting systems
• Solar project pricing and installation cost breakdowns
• Solar savings calculations and customer proposal presentations
• Integration with solar sales and installation workflows

Roofing Proposal Software
Roofing contractors must create accurate estimates based on roof measurements,
rooftop design layouts, material requirements, and labor costs. Sunbase roofing proposal software helps contractors generate professional roofing proposals that combine roof inspection data, rooftop measurements, material estimates, and project pricing in one clear proposal.
Instead of manually calculating roofing estimates using spreadsheets, Sunbase allows roofing teams to quickly generate proposals based on roof dimensions, material selections, and installation requirements, ensuring accurate project pricing and faster customer approvals.
From roof inspection and rooftop design planning to bill of materials (BOM) generation and proposal presentation, Sunbase helps roofing contractors streamline the entire estimating and proposal workflow.
Key capabilities include
• Rooftop measurement and roofing layout visualization
• Roofing material estimation and bill of materials (BOM) generation
• Labor cost calculations and installation cost estimation
• Scope of work documentation for roofing projects
• Professional roofing proposal creation and customer presentations
• Integration with roofing sales and project workflows

Construction Estimation & Takeoff Software
Construction companies must generate accurate project bids based on material quantities, labor costs, equipment usage, and project timelines. Sunbase construction estimating software helps contractors prepare professional project proposals that combine quantity takeoffs, cost estimation, bill of materials (BOM), and project scope documentation in one streamlined workflow.
Instead of manually calculating project estimates across spreadsheets and disconnected tools, Sunbase allows construction teams to create detailed project estimates based on material quantities, labor requirements, equipment costs, and construction schedules.
From project takeoffs and material estimation to bid preparation and proposal presentation, Sunbase helps construction contractors generate accurate bids and manage project proposals more efficiently.
Key capabilities include
• Quantity takeoff and material estimation for construction projects
• Bill of materials (BOM) generation for project components
• Labor cost estimation and workforce planning
• Equipment and resource cost calculations
• Construction bid preparation and proposal documentation
• Integration with construction sales and project workflows
