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.
-
Audit
We map your current gateways, VAT registrations and reporting. We mark every gap and revenue leak first.
-
Design
We pick the right acquirers and the right VAT scheme per market. One plan covers both stacks at once.
-
Build
We do the work with you. Gateway setups, SCA tuning and OSS/IOSS filings are wired up and tested live.
-
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.
