Building an HR Department from Scratch: A Founder’s First 100-Day Plan

For founders of growing companies, there comes a point when managing people ad-hoc fails. Employee issues and compliance risks explode, pulling leaders into endless admin work.  

This 100-day plan gives founders a clear path to build a real HR foundation, focusing first on legal safety and essential systems to protect and scale the business. 

Phase 1: Days 1-30 – Laying the Legal and Administrative Foundation 

The first month is for risk management. Founders should prioritize compliant employment paperwork and core administrative setup, shifting from informal to professional standards. 

Secure Core Employment Documentation 

Your first essential step is a signed employment agreement tailored to your province. It must define the role, pay, and important policies. This contract is your best defense, so avoid verbal deals and free templates. 

Establish a Compliant Payroll System 

Mistakes in payroll damage trust and cause legal trouble. Founders need a system—either in-house software or an outsourced partner—that correctly processes pay, deductions, and required filings. Outsourcing to an expert like Wages Canada often provides immediate relief from this complex burden. 

Develop Mandatory Workplace Policies 

You need three basic policies to meet the law and set clear rules: 

• A Health & Safety Policy for reporting hazards. 
• An Anti-Harassment Policy that meets human rights standards. 
• A Privacy Policy explaining how you handle employee data. 

Distribute these, get signed acknowledgments, and keep them on file.  

Phase 2: Days 31-60 – Building Structure and Process 

With the legal basics covered, focus on empowering your managers. Provide them with structured tools and clear processes to lead effectively. This builds managerial confidence and shows employees the systems are fair and reliable. 

Implement Foundational HR Processes 

To maintain fairness while scaling, implement clear and simple processes. This includes a repeatable onboarding routine, a defined method for booking vacation, and a step-by-step approach for performance management. This reduces confusion and documents actions. 

Define a Compensation Philosophy and Structure 

Establish a clear pay philosophy early. Draft a short document stating your market position, creating salary ranges, and outlining a bonus process. This simple structure ensures fair and transparent compensation decisions. 

Select and Deploy Foundational HR Technology 

Choose a payroll partner, a basic HR platform, and time-tracking software. Connect them to end manual work and keep everything in one spot. 

Phase 3: Days 61-100 – Planning for Growth and Culture 

The final step is strategic: creating programs that develop and retain your team. This is where HR starts driving growth, not just managing risk. 

Design a Basic Performance Management Cycle 

Performance reviews should not be a shock. Start with twice-yearly meetings to talk about goals. Teach managers how to give feedback and use a clear review form to track achievements and skills. 

Develop a Professional Development Strategy 

Support your team's growth to keep them engaged. Provide a budget for courses, connect them with mentors, and clarify what it takes to advance. This commitment is key to retaining your best people. 

Phase 4: Days 1-100 (Ongoing) – Ensuring Continuous Compliance 

Think of compliance as routine maintenance, not a single project. Since employment laws are always updating, you need to regularly check your own rules to stay legally safe. 

Schedule Quarterly Policy and Process Reviews 

Spend a few hours every quarter on your HR health. Update your handbook, verify your payroll using the latest tax tables, and ensure your workplace posters are not outdated. 

Maintain Meticulous Employee Records 

Use a locked digital system to store employee documents like contracts and reviews. Keep them for the required number of years. If your files are a mess, you lose credibility fast in any audit or claim. 

Phase 5: Beyond 100 Days – Scaling the HR Function 

With core HR processes in place, the next step is bringing in an expert. This move transitions people management from a founder's side task to a dedicated function that drives growth. 

Hiring Your First HR Generalist 

You need an HR hire when you hit certain milestones, like a specific team size or a rapid scaling plan. Find someone who knows compliance but can also partner with managers to develop talent and strengthen your culture. 

Integrating HR into Company Leadership 

Give your HR lead a voice in leadership meetings. When they share insights on turnover and morale, they become a true partner in your business decisions. 

Build Your HR Foundation with Confidence 

For founders, building HR is the ultimate operational challenge. A single error in payroll or policy has serious consequences.  

To ensure it is done right, you can get expert guidance from a leading HR & Compliance Administration firm. Partnering with experts like Wages Canada creates a secure and scalable foundation so you can focus on what you do best.
