Definition
Progress billing Billing is a payment method in contracting and construction where the client pays the contractor in stages as the work progresses, based on the actual progress of work, rather than in making a single final payment.
The process involvestypically includes:
Agreeing on the total contract value and work schedule.
Dividing the project into measurable phases or percentages of completion.
Submitting progress reports at agreed Submit Payment Applications based on Progress Reports at regular intervals (e.g., monthly) to confirm completed work.
Receiving payment for the portion completed, not the entire project, upfront.

document completed work.
Registration of Payment Certificates Received from client to record certified value of work done.
Generating Progressive Invoices, adjusted for any advances received and retentions withheld.
This approach ensures that payments are directly tied to certified project progress, supporting contractor cash flow while protecting the client’s financial interests.
