Payroll is the module where a small mistake costs real money, and a borrowed spreadsheet makes small mistakes too easy to make. The goal isn’t to replicate an accounting suite; it’s to keep pay accurate, approval decisions visible, and history easy to pull up when someone asks.
Here’s how to think about the pieces: payslips at the center, with advance payments, overtime, expenses, and leave encashment feeding into a clear, role-based picture of who gets paid what.
Payslips are the record that matters most. In SimpleHR, pay periods can be monthly, weekly, or daily, and most fields are optional, so you can create a one-line salary slip or a detailed breakdown with deductions, whichever your team needs.
Who sees what
Advance payments cover situations where an employee needs part of their salary early (medical bills, rent, an unexpected expense). Instead of an informal arrangement, make it a tracked, approvable request that repays through future deductions.
The employee specifies the amount, the number of repayment installments (default 1), and a reason. The manager or admin approves or rejects, and the employee is notified of the decision.
A salary advance should be a visible, approved line item, not a favor that lives in someone’s inbox.
Overtime is easy to lose track of when it’s logged informally. Employees declare their overtime (date, hours, and reason), and a manager or admin reviews and approves it, so it can be compensated reliably on top of regular salary.
| Module | Who requests | Who approves |
|---|---|---|
| Advance payment | Employee | Manager or admin |
| Overtime | Employee | Manager or admin |
| Expenses | Employee | Manager or admin |
| Leave encashment | Employee | Manager or admin |
Expense reimbursement deserves more than an email thread and a photo of a receipt. Employees submit expenses with a receipt image, and the receipt is stored securely (in a private cloud bucket in cloud deployments, or in a private local folder when self-hosted).
Only authorized people can view a receipt: the employee who submitted it, their managers, and admins. That keeps sensitive images out of shared drives while still giving approvers what they need to sign off.
Across payroll, advances, overtime, and expenses, managers and admins get summary cards and charts they can filter by month, year, or all time (total amounts, pending requests, and monthly trends). That turns a pile of individual approvals into a view of what compensation is actually costing the company.
Small-team payroll works best when the pieces are connected and role-limited: accurate payslips, a visible path for advances, declared overtime, and secure expense receipts. With approval workflows and analytics in one place, you keep compensation accurate and disputes rare, and you always know where the money is going.
