Page 1 of 1 ## Frappe HR Business application An HR foundation for employee records, recruitment, leave, attendance and related workforce processes. ### Why we recommend it We recommend Frappe HR when you want several HR processes to share one employee model and approval structure. ### When to choose it - Build an employee portal covering onboarding, requests, recruitment and workforce administration. ### What to consider - Plan around compatible Frappe and ERPNext versions. Payroll and employment rules vary by jurisdiction; built-in features still need local validation and careful personal-data permissions. ### Start with this project Prototype one employee's journey from hiring to leave approval with separate employee, manager and HR roles.

It does not install dependencies or start the application. ### Official sources - [https://github.com/frappe/hrms](https://github.com/frappe/hrms) - [https://github.com/frappe/hrms/blob/develop/README.md](https://github.com/frappe/hrms/blob/develop/README.md) - [https://github.com/frappe/hrms/blob/develop/license.txt](https://github.com/frappe/hrms/blob/develop/license.txt) - [https://docs.frappe.io/hr/job-applicant](https://docs.frappe.io/hr/job-applicant) ## Kimai Business application A time-tracking foundation that connects work hours to customers, projects and activities. ### Why we recommend it We recommend Kimai when your main question is who worked on which client or project and for how long. ### When to choose it - Build project timesheets, agency time accounting or a reporting workflow connected to billing. ### What to consider - Kimai uses Symfony rather than Laravel and is not a complete HR suite. Check the availability and terms of optional extensions and validate local time-recording requirements. ### Start with this project Record a sample project week, review the report with a manager and test the required billing export.

Validate migrations, local HR rules and the chosen modules' behavior before adoption. ### Start with this project Follow one candidate through application, interview and employee creation, then test manager and employee permissions.

Assess upgrade effort and local personal-data requirements. ### Start with this project Compare the Starter screens and permissions against one real HR process before planning custom modules.

Complex country-specific leave rules, payroll links and broader HR functions may require additional development. - At the source check, the latest repository push was in March 2024 and the README referenced an old Node.js baseline. ### Start with this project Test leave balances, overlapping requests and manager approval using your company's actual rules.
