Del. Code tit. 29 § 6411
All agencies are directed to remit payment for services rendered by the Department of Technology and Information within 30 days of receipt of invoice. Services may include, but are not limited to, postal metering, distribution supplies, telecommunication and telephone services, professional services, and data processing services.
If a prompt payment problem exists, the Department of Technology and Information may require all agencies and school districts receiving services to make monthly estimated payments toward their invoice. The estimated payments should be equal to the average of the last three months of reconciled payments or based on a schedule established by the department. The department will continue to be responsible for the actual payments to telephone companies and other vendors. In addition, the department will be responsible for the reconciliation of accounts with the user agencies and school districts.
