The direct answer
Review a contractor payment schedule by matching every payment to a defined milestone, understanding what the deposit funds, confirming how stored materials are documented, checking whether early payments exceed visible progress, and reserving a meaningful final amount until agreed completion and closeout items are delivered.
What to check in the documents
Deposit purpose
Understand whether the deposit reserves scheduling, funds permits, orders custom materials, mobilizes labor, or serves another documented purpose.
Milestone definitions
Use observable accomplishments such as rough inspection approval or cabinet delivery instead of dates alone or vague percentages complete.
Stored materials
Identify ownership, invoices, insurance, storage location, protection, and whether products are properly allocated to the project.
Change-order billing
Confirm when approved changes are billed and whether deposits, markup, or schedule extensions apply before changed work begins.
Final payment
Connect final payment to agreed completion, inspections, punch-list handling, warranties, manuals, releases, and required closeout documents.
Warning signs to clarify
- Most of the contract price is due early
- Milestones are based only on calendar dates
- Payment is required before materials are ordered without supporting terms
- No procedure for disputed or incomplete work
- Final payment is due before punch-list or closeout responsibilities
Questions to ask the contractor
- What work or material supports each payment?
- How will completion of a milestone be documented?
- Who owns and insures paid-for stored materials?
- How are approved changes added to billing?
- What must be complete and delivered before final payment?
Practical context
Example: equal monthly payments may not follow progress
Construction spending is rarely even from month to month. A schedule of equal date-based payments can move ahead of work during a delay or fall behind during heavy procurement. Milestone-based billing gives both parties a clearer basis for deciding when payment is earned.
