FAQ

Is advance payment always bad?

No, but a high advance increases owner risk before visible site progress.

Why keep retention?

Retention helps protect against incomplete work, defects, and unresolved handover items.

Should milestones total 100%?

Yes. If they do not total 100%, the payment schedule should be corrected before signing.
