Services

Six areas, one team. Ongoing work is billed as a fixed monthly fee based on how many receipts and employees you have. You know the cost up front.

  1. Bookkeeping

    Double-entry or cash-basis accounting, monthly or quarterly.

    • Receipts via the portal, bank accounts connected directly
    • VAT returns and EC sales lists
    • A monthly report with a few lines of comment
    • Receivables and payment reminders if you want them

  2. Payroll

    For businesses from one employee up to around 120.

    • Monthly payroll, payslips, contribution reporting
    • Registering and deregistering staff with the health insurer
    • Collective agreements, overtime, benefits in kind, travel expenses
    • Advice on employment contracts and terminations

  3. Annual accounts

    Balance sheet and P&L or cash-basis accounts – and a conversation about them.

    • Full accounts with notes for GmbH, KG and OG
    • Filing with the company register
    • Key figures compared with previous years
    • A review meeting at the office or by video

  4. Tax advice

    • Financial plans for banks and funding bodies
    • Start-up relief under the NeuFöG: what is exempt and what is not
    • Tax number, VAT ID and registrations

    • Handover options compared for tax
    • Coordination with notary and bank
    • Support in the first years after the handover

Slips of paper become numbers.

Receipts arrive however they arrive: as a photo, a PDF or in a binder. We sort them, book them and put a monthly report with a short comment into your portal.

What a month with us looks like

Fixed dates instead of last-minute calls: every month you know when we need something from you and when you get something from us.

Receipts arrive Day 1–5
  1. 1st–5th

    Upload receipts

    Snap a photo, forward a PDF or drop it into the portal. Bank statements arrive automatically via the bank connection.

    Paper works too. If you prefer bringing a binder, bring a binder. We scan it, and you still see every receipt in the portal.

  2. 6th–10th

    We do the books

    We collect our questions and ask them once, together, in the portal – not ten separate emails.

  3. 15th

    Deadlines met

    VAT and payroll taxes go to the tax office. You see the amount due in the portal beforehand, with the debit date.

  4. by 25th

    Report

    Trial balance and monthly report are in the portal, with a short note on anything that stands out.

The client portal

Upload receipts, see deadlines and amounts, download reports, ask questions – in one place, any time. Sign-in is protected by a second factor, and the data is hosted on servers in Austria.

  • Deadlines with status and amount due
  • Drag-and-drop receipts, with a category
  • Messages instead of scattered emails
