Aurio
Two approaches

Your expenses need tax context

A generic expense app usually tells you how much you spent and in which category. That may be enough for a personal budget. A freelancer's tax-aware view adds different questions: whether an expense may be deductible, which quarter it belongs to, how it affects forms 303 or 130, and which deadline is approaching. Aurio calculates and estimates; it never files taxes.

Beyond recording

The expense is the start

A tax-aware view adds questions that a personal category does not need to answer.

Tax category

Separates where money went from its possible tax treatment.

Deductibility with context

Applies conservative guidance for VAT and income tax.

Calendar and forms

Connects each period with forms 303, 130 and their deadlines.
