Making change is when you add cash to a point (for example, for giving change to customers) that is not tied to revenue.
- Open "Money" → "Balances and Collections".
- Next to the till you need (zone or "Goods"), click "Make Change".
- Enter the amount, save.
What to Do If… #
…you need to make change for "Abonements"? That button is intentionally absent — this till only holds amounts actually paid by clients.
