1Channel Expense Management is a cloud-based claims and reimbursement module for organizations with distributed field teams. Administrators set expense categories, claim limits, receipt requirements, and approval levels. Employees submit claims in the mobile app, attach receipt photos or PDFs, and save drafts offline to sync when reconnected. Claims are checked against configured policies and routed through reporting hierarchies; higher-value claims can require multiple approvals. Travel claims can be calculated from GPS-logged distance. Employees track claims through processing and disbursement, and approved reimbursement data syncs with Attendance Closure for payroll. Managers review claims and export reports by category, employee, and period. Workflows cover travel, fuel, meals, accommodation, communication, and daily allowances for field sales, retail, FMCG, pharmaceutical, logistics, insurance, real-estate, and service teams.
