Never miss a lien deadline or a retention check again

Monthly billing was a high-stakes scramble where one missed date could permanently kill the right to get paid. We built the system that made it routine.

How an electrical sub stopped missing lien deadlines
01The situation

Monthly billing meant rebuilding pay applications in spreadsheets with broken links, chasing retention held across jobs, generating the right lien waiver each cycle, and tracking lien deadlines by state, where one missed date permanently kills the right to get paid. Cash sat 90 days out.

02What we built

A billing system sized for a small sub, not a general contractor. It generates pay applications that reconcile to the penny, tracks retention and release eligibility per job with the current state caps built in, produces the correct conditional and unconditional waivers automatically, and runs a deadline engine that counts down every preliminary notice and lien window with plain alerts. It syncs to the books they already keep in QuickBooks.

03How the engagement worked

A ten-week build, with a construction attorney reviewing the deadline rules before launch, then quarterly updates as state retention law changes.

04The outcome

Billing day went from two stressful days to an afternoon. Not one deadline missed since launch. Days to payment trended down as draws stopped bouncing for paperwork errors. This is the kind of hard, boring, high-stakes place other vendors avoid, and exactly where going deep pays off.
