Practical use cases for hourly invoices in construction

Subcontractor payroll reconciliation

A subcontractor submits daily digital timesheets that are consolidated into a single invoice with itemized hours and approved rates

  • Field supervisors sign off electronically
  • The GC receives a standardized invoice that matches payroll records

Resulting in faster verification and reduced back-and-forth when approving payments.

Change order labor billing

A general contractor logs additional hours for a change order and creates an attached invoice documenting hours, crew, and task codes

  • The invoice includes overtime calculations and contractual markup
  • The owner reviews line-level details before authorizing payment

Leading to clearer change order settlements and fewer disputed charges.
