People is the register of the human side of your business. Every employee has one record here: where they sit — their department and branch — who they report to, when they joined, and the two numbers the rest of the application borrows from them: what an hour of their time costs the business, and what an hour of it can be charged at.
It is the foundation under Time Tracking (Chapter 9): no employee record, no timesheet. Its headcount feeds the governed numbers in Chapter 2. And it holds Contacts — the named people at your customers and suppliers whom your team actually deals with (§8.5).
One boundary, stated plainly: People is not a payroll. It keeps no pay runs, no tax or pension deductions and no payslips. The record carries the bank details a payroll provider — or a manual pay run — needs, but paying people happens outside this application. What People guarantees is that the record of who works here, and what their time is worth, lives in one place, stays current, and is shared by every module that needs it.
