Most HR guides are written for people who already have an HR department. This one isn’t. If you run a business with anywhere from a handful of employees to around fifty, and you’re the one who ends up handling hiring, payroll, leave requests, and the occasional awkward exit conversation, this guide is for you.
Nothing here requires hiring an HR manager, buying software, or reading legislation cover to cover. It is a practical walk through of the things that actually need to be in place, in the order they tend to matter, with a calculator linked at each step so you can do the actual maths rather than guess at it.
Do You Actually Need “HR” as a Function?
Not necessarily, and that is worth saying clearly before anything else. HR is not a department you need to build. It is a set of responsibilities that exist in your business whether or not anyone has a job title for them: someone has to write offer letters, run payroll correctly, track leave, and handle an exit properly when it happens.
The goal of this guide is to make sure those responsibilities are covered well, not to convince you to formalize them into a bureaucracy your business doesn’t need yet. A five person business and a fifty person business both need the fundamentals below. They just need different amounts of process around them.
The Legal Thresholds Every Small Business Should Know
A lot of confusion in small business HR comes from not knowing which laws apply at which headcount. Here is the reference most owners end up needing sooner or later.
| Requirement | Applies When |
|---|---|
| Shops and Establishments Act registration | Every commercial establishment, regardless of size (state specific process) |
| ESI (Employees’ State Insurance) | Generally 10 or more employees; individual employee coverage applies only below Rs 21,000 monthly wages |
| Gratuity | 10 or more employees, and the obligation continues even if headcount later drops below 10 |
| POSH Internal Committee | 10 or more employees, under the Prevention of Sexual Harassment Act, 2013 |
| PF (Provident Fund) | 20 or more employees is the mandatory threshold; smaller businesses can register voluntarily |
| Professional Tax | State specific, generally applies regardless of employee count wherever the state levies it |
Since November 2025, most of the central labour laws behind these requirements, including the Payment of Gratuity Act, have been consolidated into four new Labour Codes. The practical thresholds above are largely unchanged, but implementation is still rolling out state by state through 2026, so it is worth confirming your specific state’s current status with a compliance professional rather than assuming uniform rules everywhere.
Step 1: Build a Real Hiring Process
Hiring is where most of the downstream HR problems either get prevented or get created.
Write a real offer letter, not just a CTC number. The single most common source of new hire frustration is a CTC figure with no breakdown, followed by a payslip that looks smaller than expected. Every offer should include a clear salary breakup showing Basic, HRA, allowances, and the employer side contributions that make up the rest of the CTC. If you want the full explanation of why this gap exists and how to explain it clearly, see our guide on CTC versus in-hand salary. The CTC Breakup Calculator and In-Hand Salary Calculator will do the actual maths for any offer you’re preparing.
Structure Basic salary correctly from day one. Since the Code on Wages took effect, Basic plus Dearness Allowance must make up at least 50 percent of total remuneration. Getting this right in your very first offer letters saves a messy correction later.
Track your hiring process, not just your headcount. Three numbers are worth knowing even for a small business: how much each hire actually costs you (the Cost Per Hire Calculator), how long it takes from a candidate entering your pipeline to accepting an offer (the Time to Hire Calculator) or how long a role sits open overall (the Time to Fill Calculator), and what share of the offers you extend actually get accepted (the Offer Acceptance Rate Calculator). None of these require a recruiter to track. They just require noting a few dates.
Step 2: Get Payroll and Compliance Right From Day One
This is the part of small business HR with the least room for error, since mistakes here tend to compound quietly for months before anyone notices.
Deduct what you’re actually required to deduct. Depending on your headcount and each employee’s wages, this typically includes Provident Fund, ESI where applicable, Professional Tax, and TDS. The PF Calculator and ESI Calculator handle the two most commonly miscalculated deductions.
Issue a proper payslip every single month. A payslip is not optional paperwork. It is what an employee relies on for loan applications, tax filing, and simply understanding their own pay. The Payslip Generator produces a clean, print ready payslip without needing separate payroll software.
Calculate overtime correctly, not approximately. Overtime pay has specific statutory rules depending on your state and industry, and getting it wrong is one of the more common small business compliance gaps. The Overtime Calculator applies the correct multiplier so you’re not estimating.
Know your salary components properly, including TDS on salary. The TDS Calculator and Professional Tax Calculator cover the two deductions that vary the most by individual circumstances and state.
Step 3: Put a Basic Leave Policy in Writing
Even an informal small business needs a written leave policy, if only because unwritten policies tend to be applied inconsistently, which creates real resentment over time.
At minimum, decide and document: how many casual, sick, and earned or privilege leave days employees get annually, whether unused leave carries forward, and whether it can be encashed. The Leave Balance Calculator keeps a running tally for each employee so leave disputes come down to a number, not a memory. If your policy allows unused leave to be paid out, the Leave Encashment Calculator handles that calculation directly.
Step 4: Plan for the Exit Before It Happens
Every employee who joins your business will eventually leave it, whether through resignation, retirement, or something else. Handling exits well protects you legally and keeps your reputation intact with future hires who will inevitably talk to people who left.
Understand gratuity eligibility before someone resigns, not after. Gratuity becomes payable after 5 years of continuous service for most employees, with important exceptions, including a newer rule that gives fixed-term employees pro-rata gratuity after just 1 year. The full breakdown, including worked examples, is covered in our gratuity calculation guide, and the Gratuity Calculator handles the actual computation, including the correct formula and any rounding for partial years.
Get the full and final settlement right. This typically includes any pending salary, encashable leave, gratuity if applicable, and the correct tax treatment of each component. Rushing this step is a common source of disputes that were entirely avoidable with a clear checklist.
Step 5: Measure the Things That Predict Problems Early
Most small businesses only start paying attention to turnover and engagement after they’ve already lost someone they didn’t want to lose. A handful of simple, regularly tracked numbers catch problems earlier.
Turnover and retention. The Employee Turnover Calculator and Retention Rate Calculator give you the two sides of the same picture. A rising turnover number, even in a small team, is worth investigating before it becomes a pattern.
Engagement and satisfaction. A short quarterly pulse check, turned into a number using the Engagement Index Calculator or the simpler Employee Satisfaction Score Calculator, tells you far more than waiting for someone to hand in their notice. Our guide on employee engagement for small businesses covers exactly what to focus on without needing an enterprise budget. The eNPS Calculator is a useful complement if you specifically want to know how likely your team is to recommend working at your business to someone else.
Absenteeism. The Absenteeism Rate Calculator flags a pattern that often shows up well before someone actually resigns.
Step 6: Invest in People Once the Basics Are Solid
Training and development tend to get pushed to the bottom of the priority list in a small business, which is understandable, but a small amount of structured investment here goes further than most owners expect.
Set a training budget deliberately, rather than reactively. The Training Budget Calculator helps you plan this against your headcount and priorities rather than approving requests one at a time with no overall picture.
Check whether training actually paid off. The Training ROI Calculator compares what a program cost against its measurable benefit, which is useful both for justifying future spend and for being honest with yourself about what didn’t work.
Know where your team’s skill gaps actually are before choosing what to train on. The Skill Gap Estimator compares what your team currently has against what their roles require, so training budget goes toward the gaps that matter most.
A 90 Day Starting Checklist for a New Small Business
If you’re setting up HR fundamentals from scratch, this is a reasonable order to tackle them in.
Days 1 to 15: Register for Shops and Establishments, confirm whether ESI or PF thresholds currently apply to you, and set up a proper offer letter template with a full salary breakup.
Days 16 to 30: Build your payroll process, including the correct deductions and a proper monthly payslip for every employee.
Days 31 to 45: Write down a basic leave policy, even a simple one, and start tracking leave balances properly.
Days 46 to 60: Set up a lightweight way to track hiring metrics (cost per hire, time to hire, offer acceptance) so future hiring decisions are based on data, not memory.
Days 61 to 75: Run a first engagement or satisfaction pulse check to establish a baseline before you need one urgently.
Days 76 to 90: Document your full and final settlement process, including gratuity eligibility rules, so an eventual exit doesn’t need to be figured out from scratch under time pressure.

Frequently Asked Questions
At what point does a small business need to hire a dedicated HR person? There’s no fixed headcount rule, but many businesses start feeling the need somewhere between 20 and 50 employees, when the owner can no longer handle hiring, payroll, and people issues alongside actually running the business. Below that, the responsibilities can usually be covered directly with the right tools and a bit of structure.
What’s the single most important thing to get right first? Payroll compliance. Mistakes in PF, ESI, or TDS deductions compound over time and are far more expensive to fix retroactively than to get right from the first payslip.
Do I need a written HR policy even with just 5 employees? A full policy document isn’t essential that early, but a written leave policy and a standard offer letter template are worth having regardless of size, since both prevent the most common early disputes.
How do the new Labour Codes affect a small business specifically? Most day to day obligations remain similar to before, but a few specifics changed meaningfully, including the 50 percent wages rule affecting salary structuring and new gratuity eligibility for fixed-term employees after just 1 year. Both are covered in more depth in our gratuity and CTC guides.
What should I track even if I don’t track anything else? Turnover and a basic engagement pulse. Both tend to surface problems weeks or months before they show up as a resignation, which gives you time to actually do something about it.
Where to Go From Here
This guide covers the fundamentals, but every section links to a calculator built specifically for that step, and the deeper guides on gratuity, CTC versus in-hand salary, and employee engagement go further into the topics that tend to raise the most questions. Bookmark this page. Most small businesses don’t need all of this on day one, but nearly all of them need it eventually, and it’s easier to build it deliberately than to patch it together after something goes wrong.
