Accurate invoices support preliminary notices—ask a construction attorney for state-specific steps.

Retainage on every draw?

Show it explicitly so your customer’s accounting matches yours.

Union or prevailing wage?

Break out classifications as required by your contracts and regulations.

Contractors need invoices that match how jobs actually progress—especially when owners finance through banks and GCs batch pay weekly.

Tie invoices to percent complete or milestones your customer already approved. Photos and signed daily reports back up your numbers.

Text approvals are better than nothing, but signed change orders protect you. Invoice extras separately from base contract work.

Stage material purchases against deposits or lines of credit. Invoice early in the week to land in Friday pay runs.
