How do you record business costs in NettoWise

NettoWise keeps input intentionally simple so you can get insights quickly without running a full bookkeeping system. Here is how it works and what happens behind the scenes.

Add costs manually

You add costs per tax year in the portal.

1. Go to Portal -> Data -> Expenses.
2. Click Add.
3. Enter the details and save.

Meaning of the fields

When you add a cost, you decide how it should be treated.

Cost type

The type indicates what kind of cost it is. This keeps your overview organized and helps group costs logically.

Frequency

Here you set how often the cost applies:

• One-time: a single expense that applies once.
• Monthly: a recurring expense that applies each month.
• Yearly: a cost that applies once per year.

Negative costs and corrections

You can also use negative amounts. This is useful for corrections or to reverse a previously entered cost. NettoWise applies it in the same period where you enter it.

Example: correction and spreading

Suppose you enter a one-time cost of € 1,200 in June. NettoWise spreads this over the remaining 7 months, so € 171.43 per month. Later you discover the cost was not business-related. You then enter a correction of -€ 1,200 in August. The correction is spread over the remaining months (August through December), so you will see a negative amount per month that offsets the earlier cost.

Why NettoWise does not require invoices or VAT

NettoWise is not a bookkeeping tool. We do not require invoice numbers or VAT details, because the goal here is to calculate your profit and net income. That keeps input fast and low friction.

What happens technically when you save

Your costs are stored per tax year and immediately included in your calculation. For recurring costs, the amount is distributed over the relevant months. This keeps your overview consistent and makes it easy to review what you entered per year.
