Discover all our ProductsContact us

Start with one integration, scale across markets. Stay compliant with every transaction.

With fiskaltrust, your PSP integration covers fiscal requirements in Austria, Germany, France, Italy and beyond.

Fiscalization Compliance Built Into Your Payment Flow

fiskaltrust connects payment flows with fiscal compliance. Our middleware ensures that every transaction processed through a PSP can be linked to a compliant, audit-proof receipt.

  2. Payment at POS

    POS sends payment request to PSP’s gateway.

  3. Authorisation

    PSP routes to card schemes or payment rails.

    Banks approve/decline, PSP returns result to POS.

  4. Fiscalisation

    fiskaltrust generates a compliant receipt.

    PSP transaction data (amount, method, ID) is tied to the fiscal journal.

  5. Receipt Linking

    A fiscal receipt ID connects PSP authorisation data with signed journal entries.

  6. Reporting & Storage

    Receipts are stored locally or in the cloud, and reported to tax authorities in real time or during audits.

  7. Settlement

    PSP settles funds to the merchant. Reports may include fiscal references for reconciliation.

  8. Audit

    Authorities check that every PSP transaction has a matching fiscalised receipt.

PSP’s Problem

PSPs already carry heavy compliance weight: PCI, PSD2, AML. On top of this, every fiscalised country adds its own technical rules for receipts, signatures, and reporting.

Each market forces you to build a custom integration, slowing merchant onboarding and inflating support costs. When tax rules change, your teams scramble with patches and updates. Compliance becomes another drag on margins.

Monitoring is built in. Legal changes flow through the platform automatically. You stay focused on scaling transactions, not untangling tax laws.
