The client is an independent federal agency based in Washington, DC that provides conflict resolution services to industry, government agencies, and communities from ten regional offices and over 60 field offices. Its travel and miscellaneous expense vouchers moved entirely on paper: invoices could only be submitted by mail, receipts were handled by mail, and payment went out as paper checks through the postal service. i3solutions built an electronic voucher system to replace it, a secure cloud-based custom web application in which staff submit a voucher with its staff information, transportation costs, expenses, comments, and attachments, and reviewers then authorize, audit, and pay it without any of it going through the mail. i3solutions reviewed the existing process before building and applied Business Process Management (BPM) principles, so this was process automation and not a paper form moved on screen: a one-voucher-at-a-time rule prevents multiple unsubmitted vouchers, a search feature retrieves previous vouchers, administrators control users, departments, roles, and per diem rates, and accountants control fiscal year budgets, field budget allocations, fund numbers, and the lookup values vouchers are built from. CONUS and OCONUS per diem rates for lodging and meals published by the Defense Travel Management Office load in XML format and update automatically each year, and the accounting lookup values update automatically each month. The system is an ASP.NET and C# application over Microsoft SQL Server, with pay.gov handling payment electronically, SQL Server Reporting Services handling reports on voucher processing and user activity, and SMTP notifying users when a voucher is submitted, approved, and paid.
