Custom HR Management System

Stop paying per-employee for HR features you don't use. Build an HRMS that matches your organization's actual processes.

BambooHR, Gusto, Namely, Rippling — every HR platform charges per employee per month and gives you a generic set of features designed for the average company. But your organization isn't average. Your onboarding has specific steps, your leave policies are unique, and your compliance requirements are industry-specific.

A custom HRMS eliminates the compromise between what your HR team needs and what your platform provides. Purpose-built employee records, your exact leave policies, integrations with your payroll provider, and compliance tracking that matches your regulatory requirements.

We build HR systems for companies with complex organizational structures, multi-province compliance needs, industry-specific certifications, and teams that have outgrown the one-size-fits-all approach of SaaS HR platforms.

When Custom HRMS Makes Sense

For companies under 50 employees with standard HR needs, BambooHR or Gusto is probably fine. Custom HRMS makes sense for organizations with complex compliance requirements, multi-location operations, industry-specific HR workflows, or per-employee SaaS costs exceeding $15,000/year.

Common triggers: you're maintaining spreadsheets alongside your HR platform because it can't track what you need, your compliance audits require manual data gathering across multiple systems, or your HR team spends more time fighting the tool than helping employees.

US Compliance Built In

US HR is complex. State employment standards vary significantly, holiday schedules differ by state, and payroll rules change regularly. Off-the-shelf HR tools often handle multi-state requirements as an afterthought.

We build HRMS platforms with US compliance as a first-class feature: state leave entitlements, holiday calculations by state, W-2/1099 generation support, and integration with payroll providers like ADP, Gusto, and Rippling.

Integration With Your Existing Tools

A custom HRMS doesn't replace everything — it connects everything. We integrate with your existing payroll provider, benefits administration, recruitment tools (Greenhouse, Lever), learning management systems, and accounting software.

The result is a single source of truth for employee data that feeds all your other systems automatically. No manual exports, no sync issues, no conflicting data.

Frequently Asked Questions

How much does a custom HRMS cost?
Most custom HRMS projects range from $50,000 to $120,000. For a 200-person company paying $12/employee/month for BambooHR ($28,800/year), custom HRMS typically pays for itself within 2-3 years.
Can you handle US payroll?
We integrate with US payroll providers (ADP, Gusto, Rippling) rather than building payroll from scratch. Payroll calculation is complex and heavily regulated — it's better to use a specialist provider and integrate tightly with your HRMS.
How long does it take to build?
Core HRMS (employee records, leave management, self-service portal) takes 10-14 weeks. Adding payroll integration, compliance tracking, and advanced analytics extends to 16-24 weeks.
Can you migrate from BambooHR?
Yes. BambooHR provides CSV exports of all employee data. We handle the full migration including employee records, leave balances, documents, and historical data.
