revenue recognition in the construction industry

Two undergraduate accounting learners discussed the timing of revenue recognition for long-term construction contracts in their online course discussion area. The discussion focused on which method was most like the typical revenue recognition method of recognizing revenue at the point of product delivery. William argued that recognizing revenue upon project completion was preferable because it was analogous to recognizing revenue at the point of delivery. Sarah disagreed and supported recognizing revenue over time, stating that it was analogous to accruing revenue as a performance obligation was satisfied. Sarah also pointed out that as an advantage of recognizing revenue over time is that it provides information sooner to users.
