Built for §25a UStG margin-scheme dealers

Margin-scheme bookkeeping, without the spreadsheet.

From the purchase to the settlement

One workflow for the margin scheme.

Record purchases where you buy

Record a lot bought from a private seller on your phone, have the seller sign on screen, and keep working without a connection. It syncs when you are back online.

Import sales from a CSV export

Upload a marketplace CSV export, map its columns, and preview every row before anything is saved. Sales that need a decision are flagged for review.

Margin-scheme VAT per period

Pooled and individual margin-scheme calculations under §25a UStG, per settlement period, with every revision kept.

Accountant preparation

For each settlement, a preparation package for your Steuerberater: PDF, CSV and JSON with a checksummed manifest.

How it works

Four steps, every period.

  1. Record a purchase

    Add the seller, the items and the price when you buy a lot — even offline.

  2. Import your sales

    Bring in sales from a marketplace CSV export.

  3. Review flagged sales

    Resolve the sales that need a human decision.

  4. Settle the period

    Calculate the margin-scheme VAT component and prepare it for your accountant.

Works offline, at the market

Purchases you record without a signal are kept on your device and sync when you are back online.

Built with your Steuerberater in mind

Every settlement is versioned, and its preparation can be exported, so your accountant can trace each figure.
