Marapone CostLine

In development · coming soon

ARE YOU GOING TO
FINISH UNDER BUDGET?

CostLine is the financial control layer AI Estimator doesn't cover — the Estimator prices the bid once; CostLine tracks what actually happens to that budget once work starts, and produces the WIP schedule bonding companies and banks ask for. Every cost line carries a real cost-to-complete forecast, not a manual guess. Opens on Pro and Firm once it ships; still being built today.

Start on Pro today — CostLine opens the moment it ships → See it on the roadmap

No screenshots or a demo run yet — those come from the finished application, not a mock-up, and go up here the moment it is done.

Where it picks up

AI Estimator prices the bid once, at tender. CostLine is what happens after: budget vs. committed vs. actual, by CSI division, for the life of the job — the piece none of the pre-construction programs are built to track.

What's built

THREE SCREENS,
ONE FORECAST.

Portfolio

Every job, one glance

Every active project with contract value, committed cost, forecast cost, budget variance and estimated margin at a glance, plus an over/underbilled flag per job.

Job Cost Detail

Budget, committed, actual — by division

Budget vs. committed vs. actual-to-date by CSI division, with a real cost-to-complete forecast per line and a change-order ledger tracked alongside it.

WIP Schedule

The standard percentage-of-completion report

Contract value, costs to date, estimated cost to complete, estimated total cost, earned revenue, billed to date, and over/(under) billing — with a portfolio total row. The exact format bonding companies and banks ask for.

Why the forecast isn't decorative

Two views of "what's left to spend," and the more conservative one wins.

Each cost line's estimated cost to complete takes the more conservative of two figures: remaining committed subcontract value (committed minus actual), and what the current burn rate implies (actual divided by percent complete, projected to 100%). The second view is what catches a line where the subcontract value still looks fine on paper but the crew is spending faster than they are progressing.

On the seed project used to build it, a concrete division was doing exactly that — the app correctly flagged it as a roughly $268,000 overrun risk even though nothing about the subcontract itself had changed. That is the difference a burn-rate check makes over reading the subcontract value alone.

Nothing to buy separately, ever

COSTLINE OPENS ON
PRO AND FIRM.

The same rule as everything else on the roadmap: anything shipping when you subscribe is included in what you subscribed to. Start on Pro or Firm today for the five programs that are live now, and CostLine appears in your dashboard the moment it ships — no upgrade fee, no new tier.

Start on Pro — $249/mo → See the full pricing table
