Provider uses 2-digit currency precision to display prices in a format like "100.00" as descibed in OA Billing Provider's Guide. But customers receive e-mail messages where prices are shown with 4-digit precision (e.g. 100.0000).
This behaviour is confirmed as software-related issue #PBA-81625. It will be fixed in future versions of the product.
