> Please list the responsibilities of a company with 100 employees in detail.


For a company with about **100 employees**, responsibilities are usually divided among management, finance, HR, sales, operations, IT, administration, and compliance. The exact structure depends on the industry, but the following is a fairly complete responsibility list for a typical small-to-medium-sized company.

* Business-interruption coverage.

## 25. Internal controls

This becomes increasingly important at around 100 employees.

The company should establish controls such as:

**Purchasing**

> Employee requests → manager approves → purchasing orders → goods received → accounting verifies invoice → authorized person approves payment.

**New employee**

> Manager requests position → HR approves documentation → IT creates account → equipment assigned → payroll activated.

**Departing employee**

> HR confirms departure → IT disables accounts → equipment returned → access cards returned → payroll settled → confidential information protected.

**Customer payment**

> Sales confirms order → accounting invoices → payment received → bank reconciliation performed independently.

The general principle is to avoid allowing one individual to **request, approve, execute, and verify the same financial transaction**.

## 26. Management reporting

Management needs regular information rather than waiting until problems become obvious.

A 100-person company should normally review at least monthly:

* Revenue.
* Gross margin.
* Operating profit.
* Cash balance.
* Accounts receivable.
* Accounts payable.
* Outstanding customer debts.
* Sales pipeline.
* New customers.
* Lost customers.
* Employee headcount.
* Employee turnover.
* Absence.
* IT incidents.
* Security incidents.
* Major customer complaints.
* Operational performance.
* Major project status.

## A practical organizational structure

A typical 100-person company might organize these responsibilities approximately as follows:

| Function                               | Approximate staffing |
| -------------------------------------- | -------------------: |
| Executive management                   |                  3–5 |
| Finance/accounting                     |                  3–5 |
| HR/administration                      |                  2–4 |
| IT/security                            |                  2–5 |
| Sales                                  |                10–20 |
| Marketing                              |                  3–6 |
| Customer service                       |                 5–10 |
| Operations/production/service delivery |                35–55 |
| Purchasing/logistics/facilities        |                  3–8 |

These numbers are only illustrative. A software company, manufacturer, consulting company, retailer, and web-hosting company would allocate people very differently.

### The most important distinction

For a company of this size, I would separate responsibilities into **three levels**:

**Board/CEO responsibility:**
What must the company accomplish and what risks can it accept?

**Department-manager responsibility:**
Who owns each business function and whether it is performing properly?

**Operational responsibility:**
Who actually performs each procedure every day?

The common management mistake is to have many employees who *perform tasks* but nobody who is explicitly **accountable for the function**.

For example, it is insufficient to say *“John manages the server.”* A stronger organizational definition is:

> **IT Manager is accountable for IT availability, cybersecurity, backups, access control, hardware/software inventory, vendor management, and disaster recovery. John is responsible for daily server administration.**

That distinction becomes particularly important once a company reaches roughly 100 employees.
