• Measurements, quantity take-off
• Bills of quantities
• Construction log
• Progress reports, status reports
• Amendments
• Optional document management
• Optional overview of costs from all trades
• It would also be nice, but not mandatory, to have customer and subcontractor management
• Invoicing
• Quotes
• Orders
• Delivery notes
• Invoices
• Progress invoices
• Final invoice
• Reminders
• Open item management
• Permission assignment, user management
• Mobile compatibility (mobile devices running Android and iOS), mobile data entry, etc.
• Construction site reports, notes
• Protocols
• Construction log
• Quantity takeoff, measurement
• Defect tracking
• On-premises, no cloud solution!
