From a foreign-currency receipt to a completed settlement without manual calculation.
A web system automates travel-expense processing: currencies, exchange rates, people, document numbering, reports and controlled access.
CONTEXT
Manual processing of international receipts was slow and error-prone.
Each document could use a different currency, payment date and expense category. The correct exchange rate had to follow a defined accounting rule.
The goal was a system that applies the correct rate automatically, manages numbering, validates data and produces a consistent final PDF.
Consistent settlement workflow
Users enter expense lines, person, document type and currency while the application enforces completeness.
- automatic line numbers
- document type
- currency
- person / driver
Final document generation
The completed settlement is generated as a PDF with numbering, summaries and amount-in-words logic.
- portrait PDF
- annual numbering
- totals
- amount in words
Roles and control
Administrative and operational functions are separated through role-based access.
- roles
- audit
- restricted functions
- settlement history
ENGINEERING TAKEAWAYS
Key engineering and business lessons.
- Automated rate retrieval removes repetitive work and reduces accounting mistakes.
- Business rules should live in the system rather than in user memory.
- Document numbering and PDF output should be part of the workflow architecture.
- A focused internal application can replace spreadsheets, calculators and manual procedures.
