+Instant Pay structure
+=====================
+
+This structure is used when off-cycle payslips are required to make payments to employees for
+special situations, such as one-time or advance salaries. Examples of one-time payments include:
+
+- Commissions
+- Bonuses
+- Allowances
+
+Salary Advances
+===============
+
+Employees may request a portion of their salary before the end of the pay cycle. In such cases, the
+payroll officer can issue a salary advance using the following steps:
+
+#. Create an off-cycle payslip using the United Arab Emirates: Instant Pay structure.
+
+#. Add another input of type Salary Advance and specify the amount to be paid to the employee.
 
-The *Master report* provides a detailed view of the amounts paid to employees for a specific period
-based on the payslips that are generated for them during that period with payslip lines being set as
-columns in an Excel report.
+#. Confirm the payslip and process the payment.
 
-It is mainly used to make the auditing process for the human resources department easier and faster.
+In the next cycle, when a payslip is generated for the employee using the `United Arab Emirates:
+Regular Pay` structure, another input type, `Advance Recovery` is automatically added for the same
+amount that was previously paid.
 
-To access this report, go to :menuselection:`Payroll --> Reporting --> Master Report`.
+.. tip::
+   If the employee and payroll officer agree to recover the advance over two consecutive cycles, the
+   payroll officer can adjust the Advance Recovery amount on the first payslip. The remaining
+   balance is automatically added to the following cycle.
