Free Construction Tools

Free, fast, cited construction finance & lien tools. No signup required to use them — run the numbers, then decide. Built by VoiceLogPro, the voice-to-PDF court-ready daily report.

Prompt-Pay Interest Calculator →

How much statutory interest to add to an overdue payment — all 50 states, with a cited rate table.

Retainage Calculator →

Earned, withheld, and releasable retainage — with the 50%-complete reduced-rate rule.

Why these tools exist

Contractors lose money to four avoidable things: missed preliminary-notice deadlines, under-billed retainage, signing away lien rights on bad waivers, and not charging the prompt-pay interest they're owed. Each tool above targets one of those.

Every result is backed by a cited statutory source and clearly disclaimed — these are reference tools, not legal advice.
