TAXOS

TAXOS is bookkeeping for everyone: snap a receipt, done. The app classifies every receipt for tax purposes and shows at any time what will be due to the tax office at year end – or what comes back. For freelancers, SMEs and groups of companies in Austria and Germany.

The challenge

For many freelancers and small businesses, bookkeeping is a black box: receipts pile up in a shoebox, and only the tax assessment reveals whether there is money to pay. Existing software often assumes accounting knowledge – and two countries with different tax rules do not make it easier.

The solution

A setup assistant asks for country, legal form and VAT status – from then on TAXOS knows which rules apply. Receipts arrive as a phone photo, PDF or e-invoice; TAXOS reads amount, date and tax rate and classifies them: fully, partly or not deductible, with input VAT, depreciation and a note on what is still missing for the full deduction. A fixed rule engine makes the tax decision; the AI only supplies facts. The tax meter continuously projects whether a back payment or refund is likely and suggests a monthly reserve. On top come invoices with a check of mandatory details and e-invoicing, bank matching via account statements, deadlines that account for public holidays and the figures for the VAT return.

The outcome

The result is a working web app with its own landing page, several companies per account, roles for the team and the tax adviser, and subscription billing via AUTOMATA. E-invoices are tested with the official validation software, and numerous automated checks safeguard the calculations. Next up are a field test and a review by a tax adviser. The tax estimate is guidance and does not replace professional tax advice.
