What is a special billing arrangement in Foreign Military Sales?

A Special Billing Arrangement (SBA) is an alternative to the international partner DD Form 645, FMS Billing Statement that otherwise serves as an official USG claim for payment to the international partner. In much the same manner as cross-leveling, international partners may be able to minimize cash flow using collections for all (or some as desired by the international partner) cases and average cash flows on a country (vice case) basis via a process known as special billing. Since requirements and procedures are unique to each country, they are normally established in an agreement between the international partner and DSCA. If an international partner has a SBA, total expenditures for the forthcoming billing period are subtracted from total available cash resources to determine the billing amount. The Special Bill Letter supersedes Column 14 (Amount Due and Payable) of the DD Form 645, FMS Billing Statement. SBAs are established by DSCA and managed at the country level.
