AIA Billing vs. Progress Billing
Though they sound similar, AIA billing and progress billing have key differences in format and transparency. Choosing the right method can impact how quickly and reliably contractors get paid.
- AIA billing – standardized pay apps (G702/G703) widely used in commercial projects
- Progress billing – more flexible, often based on milestones or percentages agreed with the client
How Billing Methods Affect Cash Flow
Billing structure directly impacts when money comes in. Contractors who understand the differences can plan better for expenses like payroll, materials, and equipment.
- AIA billing creates clear, lender-friendly documentation but can slow approvals
- Progress billing is faster to issue but may lack transparency
- Retainage is easier to track in AIA forms than informal progress billing
Pros and Cons of Each Method
No method is perfect—contractors should weigh pros and cons based on project type and client requirements.
- AIA billing pros: standardized, transparent, lender-approved
- AIA billing cons: slower, more paperwork, risk of errors
- Progress billing pros: flexible, faster invoicing
- Progress billing cons: less detail, higher risk of disputes
