About FiscalGeek

The fiscal geeks behind your cross-border revenue.

We are a small team of payments and EU tax specialists. We came from fintech, acquiring and cross-border VAT. We saw the same problem on repeat. Sellers run a gateway team and a tax team that never talk. So revenue leaks in the seam between them. FiscalGeek closes that seam.

Why one engagement

Payments and tax, run as one ledger

Most firms sell VAT as an add-on. Most agencies stop at the gateway. Cross-border revenue needs both to work together. A failed payment costs you a sale. A late OSS return costs you a fine. We own both halves on one team. So the two reinforce each other.

That means your authorisation rates, SCA exemptions and VAT filings get tuned in step. No hand-offs. No finger-pointing. One plan, start to finish.

How we work

From gateway audit to live launch

Every engagement runs the same four steps. Each one is hands-on. You see the work, not just a slide deck.

  1. Audit

    We map your current gateways, VAT registrations and reporting. We mark every gap and revenue leak first.

  2. Design

    We pick the right acquirers and the right VAT scheme per market. One plan covers both stacks at once.

  3. Build

    We do the work with you. Gateway setups, SCA tuning and OSS/IOSS filings are wired up and tested live.

  4. Run

    We reconcile payouts, fees and VAT line by line. Your books stay audit-ready every quarter, not just at year-end.

What we stand for

Specialist focus, held on purpose

We say no a lot. That focus is the point. Here is what shapes every engagement we take.

  • Two stacks, one team

    Payments and tax sit in the same engagement. You brief one team, not two separate firms.

  • EU cross-border, by design

    OSS/IOSS, distance-selling rules and filing across all 27 member states are our daily work.

  • Hands-on, not advice-only

    We carry out integrations, setups and filings. We stay until the new market is live and clean.

  • Gateway-agnostic

    We are advisors, not a payment provider. We pick what fits you and never lock you into our tools.
