We use single-entry accounting, which is suitable for sole traders. We take care of both the monthly accounts and the declarations to the authorities on your behalf. Your job is to provide us with the necessary materials - we do the rest.

What does this mean in practice?

✅ Bookkeeping is done on an ongoing basis, as you provide us with invoices and receipts.

✅ VAT returns are submitted according to the VAT period - either monthly, quarterly (quarterly) or once a year.

✅ Tax returns are filed once a year.

Once the mandates are in place and the material is delivered on time, the accounting will automatically roll in the background - just as it should 🔥
