The Challenges
1
Manual Calculations,
Maximum Risk
Allowance computation relied on manual validation and static spreadsheets, increasing chances of human error and delay.
2
Compliance Complexity
Frequent rule changes, rest-hour slabs, exclusions (e.g., freelancers), and cross-month calculations made accurate compliance tracking difficult.
3
Disconnected Workflows
Data had to be collected from the Crew system, processed, validated, then emailed across multiple departments and tools—slowing down the monthly process.
4
No Self-Serve Transparency
Crew members lacked access to historical per diem data and had no direct way to raise discrepancies, leading to communication gaps and delays.
5
Scalability Bottlenecks
Any extension to other client entities or introduction of new rules would require significant manual effort and technical overhead.
