One of the biggest mistakes that far too many A/E firms make is in over-estimating their percentage of completion on fixed fee projects at month end. The potential implications of this error are far reaching as it often results in overstating profit, inflated invoicing to clients and ultimately longer collection periods.
For fixed fee projects, these firms simply look at their monthly project report to see what percentage of the project budget has been expended. They then proceed, with ruthless efficiency, to invoice the client for an equivalent percentage of completion – without any regard for the percentage of work actually completed.
One can only imagine what the client’s reaction is when they receive an invoice for 50% completion when only 30% of the work has been accomplished. The A/E firm then wonders why it takes the client 120 days to grudgingly process the invoice?
