--- title: Payroll settings description: Set rounding, accounting groups, reminders, alert thresholds, reference periods, proration, 13th month and payroll engines. url: "https://illizeo.com/en/centre-aide/payroll-settings/" updated: "2026-11-11" category: Payroll / Preliminary salaries --- # Payroll settings Payroll settings set the rules shared by every month: rounding, accounting groups, reminders, alert thresholds, reference periods, proration method and additional salaries (13th, 14th, 15th month). This article goes through them page by page. It is intended for administrators and payroll managers who configure the module. ## Before you start - Settings open from **Settings › Salary & Payroll**. Each page has its own permission: **Payroll general settings** (also used for payroll engines), **Proration — Calculation method**, **Additional salary — 13th/14th/15th month**, **Reference periods**, **Compensation types — CRUD**. At the Access level you read the page; at the Execute level you change it. - The Settings menu also requires the **Settings — Access** permission. Among the default roles, the Administrator has both; another role must be given this permission to reach the payroll settings. - A field your role cannot change is shown read-only, or hidden with the note “not available with your permissions”. ## General settings Open **Settings › Salary & Payroll › General Settings**. Change the cards you need, then click **Save Changes** at the bottom of the page. ![Payroll general settings: rounding rules (Base salary 0.05, Bonuses & Premiums 0.01, Advances & Loans 1.00) and Accounting group with its eight options, Do not group selected.](https://i0.wp.com/illizeo.com/wp-content/uploads/2026/11/paie-10.en_-scaled.png?resize=800%2C514&quality=80&ssl=1) General settings: rounding and accounting group. ### Rounding rules by type Choose the rounding precision of each family: **Base salary** (fixed salary, hourly, prorated), **Bonuses & Premiums**, **Advances & Loans**. The values offered are 0.01, 0.05, 0.10 and 1.00; in Switzerland, 0.05 is common for salaries. ### Accounting group The accounting group splits payroll: each group produces a separate export and is approved independently. Choose **Do not group** (all employees in a single export), **Sub-company**, **Department**, **Workplace**, **Salary type** (fixed and hourly separated), **Occupation type**, **Nationality** or **Marital status**. The groups then appear in the breadcrumb at the top of the payroll screen. ### Payroll - **Attributes in payroll exports**: the employee data added to the exports (notably the accounting export). Pick them from the list. - **Separate salary tab**: shows or hides the Salary data tab of the payroll screen. - **Add an absence type**: the absence types carried into payroll. ### Reminders Turn on **Send the monthly reminder** and choose the **Monthly reminder day** (1st to 28th): administrators receive a reminder to check the payroll cycle, and the day is shown under the month on the payroll screen. ### Alert thresholds - **Alert threshold — Salary variation** (± 3% to ± 20%): an alert is raised if an employee’s gross salary varies by more than this threshold; Medium severity above the threshold, High above three times the threshold. - **Alert threshold — Produced amount** (± 20% to ± 100%): an alert is raised if the amount actually produced varies by more than this threshold, for example when an hourly employee’s hours change sharply from one month to the next. ### Global notifications Turn on the email and in-app alerts sent to payroll administrators: **Unvalidated payroll**, **Late cycle**, **Approaching deadline**, **Temporary role expiration**, and set the **Notification delay before deadline** (1 to 7 days). ## Reference periods The reference period sets the dates of each month’s payroll period (for example from the 1st to the end of the month, or from the 21st to the 20th). Each group can have its own. 1. Open **Settings › Salary & Payroll › Reference Periods**. Each group is shown with its **Frequency**, its **Period**, its start date (**Since**), its scopes and its history. 2. Click **Add a group**, or **Edit** on a group. 3. Fill in the **Group name**, the **Frequency**, the **Period start** and, if you change the start, the effective date: leave it empty to apply from the current month’s payroll, or choose a later month. Earlier months keep their period. 4. If needed, set the **Payment delay (days)** between the end of a period and its payment (0 to 31), and the attached scopes. 5. Click **Save**. A group’s switch activates or deactivates it, and the bin deletes it. A scheduled change is shown on the group and can be removed. The monthly payroll screen reads monthly groups without scope; a group attached to scopes serves the payrolls calculated by Illizeo and the per-period entry of the Attendance tab. ![Reference Periods page: Add a group button and one active group, monthly frequency, period from the 1st to the end of the month, since 02.11.2026, no scope, with switch, Edit, bin and History.](https://i0.wp.com/illizeo.com/wp-content/uploads/2026/11/paie-11.en_-scaled.png?resize=800%2C251&quality=80&ssl=1) A reference period group. ## Prorata Proration sets how the month’s salary is calculated when an employee joins or leaves during the period, or when their salary, rate or contract changes. Absences are not covered: they are sent to the payroll software, which applies its own rules. 1. Open **Settings › Salary & Payroll › Prorata**. Choose the **Scope**: the whole company, or a sub-company (which otherwise inherits the company setting). 2. Choose the **Prorata method**: **Working days per contractual schedule** (recommended), **Hours per contractual schedule**, **Calendar days of the month**, **30th method**, a fixed divisor or annual working days. 3. Under **Advanced options**, adjust if needed the **Mode** (**Deduction**, recommended, or **Presence**), **Public holidays**, the **Full month rule**, the **Cap at the monthly salary**, **Minimum one day** and the **Rounding of each segment**. 4. Choose the **Effective from** date and click **Create the version**. The change applies to non-approved periods from that date; the screen says how many periods will be recalculated. The simulator compares the six methods on a hire and/or a departure, with the current setting, without saving anything. The version history keeps successive versions. The **Where this applies** card reminds you that the method applies to the profile salary, the amounts in the Payroll tab and the payroll file. ![Prorata page: whole-company scope, six methods (working days per contractual schedule selected, recommended), Advanced options, and the simulator comparing the methods for a 6,000 CHF salary in November 2026.](https://i0.wp.com/illizeo.com/wp-content/uploads/2026/11/paie-12.en_-scaled.png?resize=800%2C597&quality=80&ssl=1) The proration method and the simulator. ## Additional salaries Open **Settings › Salary & Payroll › Additional Salary**. Turn on the **13th month**, **14th month** or **15th month** and choose the **Payment months** for each; one additional salary can be spread over several months. Each is worth one monthly salary. The rule cascades: the 14th month requires the 13th, and the 15th requires the 13th and 14th. Click **Save Changes**. The number of salaries for an employee (12 to 15) is then chosen in the frequency of their base salary, within the limit of what is enabled here. ## Payroll engines If your workspace has one or more calculated payrolls (such as Swiss payroll), the **Payroll engines** page designates the payroll that calculates each scope: the company (contracts without a sub-company) and each of its sub-companies. A scope is calculated by only one payroll, and only installed payrolls are offered. Choose the engine for each row, then click **Save**. ## Good to know - A proration change never affects an already approved period. - Without an accounting group, the payroll screen shows a banner pointing to the general settings. - If your role can only change part of a page, saving keeps the permitted fields and reports the others. - Compensation types and your payroll software’s codes are set separately: see [Compensation types and payroll items](https://illizeo.com/en/centre-aide/payroll-compensation-types/). ## Frequently asked questions ### I cannot see Salary & Payroll in the settings. Your role has either none of the payroll settings page permissions, or not the Settings — Access permission. ### Which proration method should I choose? The screen recommends working days per contractual schedule. The simulator shows you the difference between methods on a real case before saving; choose the one your payroll software and your collective agreement apply. ### Why is the 13-month option not offered in an employee’s salary? The 13th month is not enabled in the additional salaries. Enable it, then choose the frequency in the base salary. ### *Similaire*
