How to Build a SaaS for HR Teams on Bubble.io
HR technology is one of the most underserved markets for niche SaaS products. Generic HR platforms are expensive and over-featured for small businesses. A Bubble.io application built for the specific HR workflow of a specific type of business delivers exactly what small HR teams need at a fraction of the cost.
Why This Vertical Is Underserved
The HR software market is dominated by large platforms that serve mid-to-large enterprises: BambooHR, Personio, HiBob. For a company with 10-50 employees, these platforms are expensive and feature-heavy. The boutique HR SaaS opportunity: a Bubble.io application built for one specific HR workflow (employee onboarding, performance review cycles, leave and absence management, or training completion tracking) for one specific type of company can deliver the specific feature set that small HR teams actually use daily, at a price point attractive relative to both the large platforms and the manual spreadsheet alternative.
What to Build
Employee onboarding automation
Creates a personalised onboarding checklist based on the employee’s role and department, sends scheduled welcome emails and task reminders, collects completed onboarding documents, tracks task completion for each employee, and reports to the hiring manager. Replaces HR managers spending 3-5 hours per new hire manually emailing onboarding materials and chasing document returns.
Performance review and feedback platform
Creates review cycles, sends review forms to employees and managers simultaneously, collects self-assessments and manager assessments, generates a consolidated review report, and tracks completion rates across the organisation.
Leave and absence management
Self-serve leave request and approval: employees submit leave requests; managers approve or decline; the system tracks leave balances; HR views a calendar overlay of all approved leave. Replaces the email-based leave request process universal in small businesses.
Training and compliance tracking
Assigns mandatory training modules to specific employee groups, tracks completion rates, sends reminders to employees who have not completed mandatory training by the deadline, and exports compliance reports for audit.

What Is a Discovery Sprint? The Smart First Step Before Building Your App
How SA’s Discovery Sprint converts an HR workflow automation idea into a buildable specification.
Q: Does an HR SaaS need to comply with employment data protection requirements?
Yes. Employee data is personal data subject to GDPR in the UK and EU. An HR SaaS must: have a lawful basis for processing each category of employee data; provide employees with a privacy notice; implement data retention and deletion policies; and provide a data processing agreement to client companies. SA builds data protection compliance workflows into every HR tech product.
Q: Should I build HR software for a specific industry or for all small businesses?
Build for a specific industry first. An onboarding platform built specifically for tech startups (with tasks like GitHub access setup, Slack workspace invitation, equipment request, tool account creation) is significantly more compelling to a tech startup HR manager than a generic onboarding platform.
Q: How do I integrate a Bubble.io HR SaaS with existing payroll software?
Most UK payroll software (Xero Payroll, Sage Payroll, Brightpay) and US payroll software (ADP, Gusto, Rippling) expose REST APIs that Bubble.io’s API Connector can call. SA configures payroll integrations as part of HR tech builds that require payroll system connectivity.
