fee bookings

[Maria Klavdieva]

Помогите, пожалуйста, перевести fee bookings в следующем контексте:

Using a simple form of earned value management provides the following benefits to any project in the management of their cost reimbursable type procurements:
1. It allows the project to focus its attention on the physical
earned value achieved to accurately measure the percentage
completion of each procurement (Earned Value divided by the
total Budget at Completion equals the percentage completion);
2. It allows the project to use seller's potential fee (Fixed or Award)as a motivator, authorizing their FEE BOOKINGS only as the phys
ical work is accomplished (not simply funds expended)

Может быть,"вознаграждение поставщику начисляется только по выполнении реальной работы, а не когда будут потраченные все выделенные средства"?
