Commercial fit-out and refurbishment contractors turn offices and commercial spaces around on tight programmes. Each project runs as its own account: a quote and a cost estimate for each package of work, then purchase orders and supplier invoices on one side, and monthly valuations, variations and retention on the other.
Margins are thin and cash depends on valuing work on time. So finance needs to know, for every project, what has been done, what has been invoiced and what is still to come. That figure, work in progress, drives the forecast and the year-end accounts.
