HR management software for companies in Spain: when custom HRIS outperforms Personio or BambooHR

Personio, BambooHR, and Factorial solve 80% of the HR needs of a mid-sized company. The remaining 20% — proprietary approval workflows, internal payroll integration, competency management modules — is exactly where these platforms create more friction than value.

• •A custom HRIS makes sense when you have more than 80 employees with complex organizational structures (matrix, project-based, functional), when integration with your internal payroll system is critical, or when approval workflows are more complex than what SaaS tools offer.
• •The hidden cost of adapting your HR operations to the data model of a standard SaaS can easily exceed the development cost: if your team spends more than 2 hours per week exporting/importing data between systems, you already have the ROI calculated.
• •Spanish companies have specific labor compliance requirements (collective agreements, ERTE/ERTO, mandatory time tracking since 2019) that international SaaS tools don't always implement correctly for Spanish regulations.
