Frequently Asked Questions
What is progress billing in construction invoicing?
Progress billing, also called schedule of values billing or percentage complete billing, allows contractors to invoice clients incrementally as defined project milestones are completed rather than waiting until the entire project is done.
What is a retention or retainage in a contractor invoice?
Retainage is a percentage (typically 5–10%) of each payment that the project owner withholds until substantial completion of the contract. It protects the owner against incomplete or defective work and is released upon final sign-off and lien waivers.
