Equipment companies want to track profitability of long-term projects which involve fixed assets. If they could link the fixed assets to a project, then the fixed asset transactions would automatically flow to the project and the project could be kept up to date.
For example: an company builds cell phone towers. Each tower becomes a project so they can track direct expenses, indirect expenses, and rental revenues for the tower. Depreciation expense is a key component of the expense line.
I have received few pre-sales requests for this over the past years.
