English to French Bus/Financial Business/Commerce (general)

J´hésite à employer la traduction "déduction" ici. Il s´agit d´une solution pour le commerce électronique et on trouve le terme à plusieurs endroits :

Identifying and processing ***vendor deductions*** is typically a complex, manual process.
The variety of trading partner connections, data complexity, and frequency of change makes it nearly impossible for your company to capture every ***deduction*** opportunity.
Many retailers identify and capture only 60% of possible ***deductions*** and are unable to recover the costs incurred from these transaction errors.
Deduction Management automates your ***vendor deduction program***.

Merci.
