Expense Station: government compliance-first travel expense automation

PM Solutions' travelers and reviewers were reconciling government-facing travel reimbursements largely by hand: matching receipts to GSA and State Department per-diem rates, watching each contract's spending against its annual ceiling, and manually completing the official government travel claim form for every trip. International travel added currency conversion, foreign-language receipts, and per-post lodging ceilings on top of routine audit and approval requirements, and any post-payment correction risked losing the original record.

Product design, application engineering, AI document processing, compliance rules-engine design, government form automation, and role-based workflow design.

Gulfturn Creative designed and built a role-based expense platform that combines: — AI receipt extraction that auto-splits multi-receipt pages, multi-page PDFs, and itemized hotel folios into confirmable line items — Daily currency conversion and foreign-language receipt translation for international travel, with the original values preserved for audit — Google Maps-powered personal-vehicle mileage with selectable routes and rendered route maps for every leg — GSA per-diem lookups for domestic travel and U.S. State Department foreign per-diem lookups for international travel, both date-aware and re-verified server-side — A configurable, rule-based compliance audit that grades every receipt and mileage leg pass, flag, or fail — Per-contract annual budget tracking with automatic administrator alerts at 75% of a contract's spend ceiling — A four-role workflow (Employee, Reviewer, Expense Admin, System Admin) with a shared reviewer queue, automated notifications, and a System-Admin-only reopen path for post-payment corrections — Export that fills the official government travel claim form in place, with fillable signature fields, continuation pages for long reports, and a matching Excel export for finance — Spend analytics covering monthly and quarterly trends, per-employee and per-category breakdowns, and contract budget utilization — An immutable, server-enforced audit trail across every privileged action

GSA Per-diem API, State Department Per-diem data, international currency converter, AI vision and OCR calls, PDF and XLSX write capabilities, Google Maps API

The platform moves compliance checking from a manual, after-the-fact review into an automated step inside the submission flow itself. Contract budgets are monitored continuously instead of discovered after an overage, GSA and State Department rates are resolved and re-verified on the server rather than trusted from the browser, and every export stays reconciled to the same underlying numbers reviewers approved. Corrections found after payment can be made without losing the original audit history.
