News and Information

· Fewer rejections, as the service includes streamlined, enhanced invoice entry and validations to prevent submission errors;


· Greater transparency with invoice payment tracking information;


· For ITSS acquisitions…no more dual submission!...a single invoice submission into the Central Invoice Service eliminates any need for redundant submission to GSA Finance and ITSS;
