Where does the completed earlier column come from?
From the previous period cumulative record, specifically its total since work began column.
What counts as an overstatement?
A line whose total since work began exceeds the design quantity. Such lines get their own status.
Are the form header fields filled in?
Yes. The contractor, client, construction site, facility, contract, reporting period, the person keeping the record and the person who checked it are entered on the page. What you type stays in the browser, is never sent to the server, and goes into the header of the result and the XLSX export. Fields left blank are omitted from the document.
How is the retainage computed?
Line by line from the value completed in the period and earlier, at the percentage set by the contract. The retainage accrues cumulatively, and once no item is left outstanding the record reminds you to invoice its release.
