HR Foundations

Startup HR Foundation Systems

A practical guide to building HR infrastructure for growing companies, covering HRIS selection, payroll setup, benefits administration, and compliance systems.

Building a solid HR infrastructure early is one of the highest-leverage investments a growing life sciences company can make. The decisions you make in the first 20–50 employees about systems, processes, and compliance frameworks will either accelerate your growth or create costly rework later. This guide walks through the core components of an HR foundation, HRIS, payroll, benefits, and compliance, with practical checklists to help you assess where you stand and what to build next.

Choosing Your HRIS

Your Human Resource Information System is the backbone of your people operations. For early-stage life sciences companies, the right HRIS is not necessarily the most feature-rich, it's the one your team will actually use and that can scale with you through your next two or three headcount milestones.

What to evaluate

  • Scalability: Can it support you from 30 to 200 employees without a full platform migration?
  • Integrations: Does it connect cleanly to your payroll provider, ATS, and benefits platforms?
  • Compliance support: Does it handle multi-state employment, I-9 management, and audit trails?
  • Regulated environment fit: If you operate in cGMP environments, consider whether the system can support role-based access controls and documentation requirements relevant to quality systems
  • Implementation lift: What does onboarding actually require from your team?

HRIS selection checklist

  • [ ] Defined current headcount and 18-month growth projection
  • [ ] Identified must-have integrations (payroll, ATS, equity platform)
  • [ ] Evaluated at least three platforms with a structured demo
  • [ ] Confirmed multi-state capability if you have or anticipate remote employees
  • [ ] Reviewed data security and SOC 2 compliance status of vendor
  • [ ] Confirmed contract terms allow for scaling without punitive repricing

Payroll Setup

Payroll errors erode employee trust quickly and create compliance exposure. Getting this right from the start matters more than most founders expect.

Core decisions to make early

  • In-house vs. outsourced: Most companies under 100 employees are better served by a managed payroll provider than running payroll internally
  • Pay cadence: Bi-weekly is the most common and operationally practical cadence for most life sciences organizations; confirm state-specific requirements before finalizing
  • Classification framework: Establish clear criteria for exempt vs. non-exempt classification, especially relevant for lab technicians, research associates, and field-based roles, misclassification is a frequent and costly error
  • Equity and bonus handling: Ensure your payroll system can handle supplemental wages, RSU vesting events, and bonus tax withholding correctly

Payroll readiness checklist

  • [ ] EIN established and state tax registrations completed in all states where employees work
  • [ ] Payroll provider selected and integrated with HRIS
  • [ ] Direct deposit authorization collected for all employees
  • [ ] Exempt/non-exempt classification reviewed and documented for each role
  • [ ] Payroll calendar published and communicated
  • [ ] Process owner identified for payroll approval and exception handling
  • [ ] Year-end W-2 and 1099 process documented

> Note: State payroll tax registration, final-paycheck timing rules, and pay-frequency requirements vary significantly by state. When you add employees in a new state, Trimaren can set up the compliance infrastructure and coordinate legal review where required. Reach out before you hire across state lines.


Benefits Administration

Benefits are a primary lever for attracting and retaining the scientific and commercial talent that life sciences companies compete for. Your benefits infrastructure needs to be administratively sound and market-competitive.

Benefits foundation priorities

  • Medical, dental, and vision: Carrier selection, contribution strategy, and plan design should be benchmarked against life sciences peers, not general industry
  • Equity: Ensure your equity plan and grant documentation process is in place before you make offers that include equity components
  • Retirement: A 401(k) plan with a reasonable employer match is expected by most experienced hires; establish this earlier than you think you need to
  • Leave policies: PTO, parental leave, and sick leave policies should be documented and compliant with applicable state mandates before your first employee starts

Benefits administration checklist

  • [ ] Benefits broker selected with demonstrated life sciences client experience
  • [ ] Open enrollment platform configured and tested before first enrollment window
  • [ ] Employee benefits guide drafted in plain language
  • [ ] COBRA administration process established (in-house or outsourced)
  • [ ] ACA compliance tracking in place if approaching 50 full-time equivalent employees
  • [ ] Leave policy documentation reviewed for state-specific mandates
  • [ ] 401(k) plan documents executed and plan administrator identified

Compliance Systems

Compliance in a life sciences HR context has two layers: standard employment law compliance and the regulated environment considerations specific to your work. Both require intentional infrastructure.

Employment compliance essentials

  • [ ] I-9 process documented and audit-ready (remote I-9 procedures confirmed if applicable)
  • [ ] Employee handbook in place, reviewed for compliance (Trimaren can build or audit this and coordinate legal review), and acknowledged by all employees
  • [ ] Job descriptions on file for every active role, with FLSA classification noted
  • [ ] Required federal and state labor law posters displayed or distributed to remote employees
  • [ ] Anti-harassment policy and training program established
  • [ ] Complaint and investigation process documented
  • [ ] Background check policy documented and applied consistently

Life sciences-specific compliance considerations

  • IP protection: Proprietary information and invention assignment agreements (PIIAs) should be executed at hire, not as an afterthought
  • cGMP environments: If employees work in regulated manufacturing or lab settings, HR records supporting training completion and role qualification may intersect with quality systems; coordinate with your Quality team on documentation standards
  • Export controls: Roles with access to controlled technology or materials may carry additional hiring compliance requirements; Trimaren can help you build the right process and coordinate specialized legal review early
  • Drug and alcohol testing: If required by your operations or contracts, ensure your policy is documented, consistently applied, and reviewed for state compliance, Trimaren can build the policy and coordinate legal review

Building Your HR Calendar

Once systems are in place, the work becomes operational rhythm. A simple HR compliance calendar prevents the reactive scrambles that consume leadership time.

Annual HR calendar anchors

  • [ ] Open enrollment planning (typically 60–90 days before renewal)
  • [ ] Performance review cycle
  • [ ] Compensation benchmarking review
  • [ ] Employee handbook annual review
  • [ ] Required harassment prevention training (state-specific deadlines vary)
  • [ ] 401(k) plan compliance testing and nondiscrimination testing deadlines
  • [ ] ACA reporting deadlines (if applicable)
  • [ ] I-9 audit
