Product/Cashflow

See the money before it moves.

Cashflow forecasting and S-curves built from the live commercial record, so payment timing is visible before the money moves.

Cash timing is a commercial fact, not a spreadsheet guess.

01 · Forecast the flow

Built from the live record.

A cashflow forecast assembled from claims, commitments and payment terms, not a static spreadsheet kept alive by hand. As the commercial record moves, the projected timing of money in and out moves with it.

02 · S-curves

Planned, applied, certified.

One S-curve carries three lines: what was planned to bill, what has been claimed, and what has been certified to pay. The gap between claimed and certified is what assessment took out; the gap back to plan is how far ahead or behind the works are running. Both read as shape, well before they reach a bank balance.

03 · Plan with confidence

The timing of money in and out is visible ahead of time, so cash decisions are made on a clear picture, not a month-end shock. No surprises before the money moves.
