This post was published in August 2014 and introduces a module built for Odoo V7. It does not work with current versions.
We have built a receipts and payments schedule list. It shows the outlook for your cash balance at future points, by taking the cash balance as it stands and adding and subtracting unreconciled receivables and payables. In concept it resembles the Stock Forecast module posted about earlier.
We built this module a while ago and released it to the community, but we have lately made improvements, Japanese among them, so we are announcing it afresh. Download it here, on the Apps page!
