Payroll system for travel and expenses
Mountalis optimized compensation inputs and expense submission processes to help teams prepare payroll with trusted data.

Client
A payroll and employee administration platform helps companies and accounting teams manage payroll preparation and employee records. Working hours, absence, expenses, reports, approvals and financial integrations are managed through a coordinated system.
Challenge
Payroll administration required confidence in the information used to calculate compensation.
Payroll data confidence
Accurate employee records, absence tracking, travel and expense data were essential for reliable salary calculations.
Expense submission reliability
Travel and expense entries had to be easy to submit, validate and approve from mobile without creating extra work for administrators.
Preparation and integration alignment
Reports, accounting integrations and preparation data had to reflect the same values before each payroll run.
Solution
- 01
Calculation input controls
Employee information was structured to support reliable compensation calculations.
- 02
Travel and expense submissions
We established a clearer path from employee entry to administrator review.
- 03
Payroll preparation screens
Redesigned administrator views reflected calculation results and reporting data in the same way.
Result
Administrative effort associated with payroll preparation decreased by 34%. More employee updates and travel submissions could be handled without increasing administrative capacity. Payroll operations remained efficient as transaction volumes increased.
