For a multi-phase project, a milestone schedule can make billing easier to follow than treating the entire project as a single final invoice. The schedule should match the contract and any applicable deposit or progress-payment rules.
Choose milestone descriptions that a contractor and customer can identify from the written scope, such as completion of a defined phase. Avoid vague labels that make it unclear what event triggers the next invoice.
ProQuote Pro milestone invoices can show the approved contract total, amount billed, amount collected, outstanding billed balance, and remaining unbilled value. That is an accounting view of the project; the contract and applicable law determine the parties’ legal payment obligations.
When scope changes after approval, document and price the change rather than silently altering the original contract amount. ProQuote Pro formal change orders preserve the original approved scope and the later adjustment as separate records.
