When a subcontractor is not paid on time, the first operational move is to organize the facts: invoice date, payment due date, contract terms, approved change orders, work proof, and prior messages. A payment delay notice should be factual, specific, and tied to the contract and applicable prompt-payment rules.
Include these details
- Project name, contract reference, and invoice number
- Invoice delivery date and amount outstanding
- Approved change orders included in the balance
- Payment due date and any notice deadline
- Request for written reason if payment is being withheld
- Attachments that prove work and approval
Not legal advice. Payment notices, lien rights, and adjudication deadlines vary by jurisdiction and contract.
