Frequently Asked Questions
How do contractors bill for large projects?
Large projects use progress billing based on milestones or percentage completion. Invoice at 25%, 50%, 75% completion, with final payment after inspection.
What is retainage on construction invoices?
Retainage is 5-10% of each payment held back until project completion. Show it clearly on invoices: 'Total due: $10,000 less 10% retainage = $9,000 payable now.'
Should contractors bill change orders separately?
Yes, always create separate invoices or clearly marked line items for change orders. Get signed approval before starting additional work.
