Guide
Build or buy your HR toolkit
When you carry the HR load yourself, every policy, tracker, and calculator is a choice. Build it yourself from a blank file, or buy one that is already built and checked. This guide walks the real tradeoff, cost, time, and risk, so you can decide per task instead of by default.

The real cost of building is not the file
Every file states the jurisdictions it covers and the date it was last reviewed.
A turnover calculator is an afternoon in a spreadsheet. Getting the replacement-cost assumptions right, checking them against current research, and making sure the formula holds when someone changes an input takes time. It is a week of part-time work you do not have. The same is true of a leave policy, an attendance points system, or a pay band structure. The template is the visible cost. The invisible cost is the research, the version control, and the sign-off, and it lands on the one person handed HR without a team.
Where building makes sense
Every file states the jurisdictions it covers and the date it was last reviewed.
Build when the work is genuinely yours. Your org chart, your specific job families, your internal comp philosophy, a workflow that only makes sense inside your operation. These are things no one can sell you off the shelf because they do not exist outside your company. Building here is not a shortcut you are skipping. It is the actual work, and no vendor can do it for you.
Where buying makes sense
Every file states the jurisdictions it covers and the date it was last reviewed.
Buy when the work is standard, carries exposure, or requires more research than drafting. A FMLA eligibility checker, a WARN Act timeline, a records-retention schedule, a cost-per-hire model. These are the same in every company. They cite federal rules that change, and a wrong answer has consequences. Buying is not paying for a document. It is paying so you do not have to become an expert in a rule you will use twice a year. It also means the figure behind your decision is defensible.
A quick test for any HR task
Every file states the jurisdictions it covers and the date it was last reviewed.
Ask three questions. Is this specific to my company, or is it the same everywhere? If a number in here is wrong, does someone get hurt or does the company get exposed? Would getting this right from scratch take me more than an afternoon? If it is standard, high-stakes, or research-heavy, buy it and spend your hours on the parts only you can do. If it is specific, low-risk, and quick, build it.
The bottom line
The point is not to buy everything or build everything. It is to stop defaulting. Build what is yours. Buy what is standard, exposed, or slow to get right. For a lean team, that split is the difference between HR that runs and HR that quietly falls behind.
Start from the standard
Every file here states what it was built against and when it was last reviewed.
