Country Prioritization by Certification Cost
All researched markets ranked by certification cost, from free to most expensive.
Pricing Model
Zyntem charges a flat fee per location with graduated tiers. Pricing is country-agnostic — adding a country doesn't change what ISVs pay, it increases the value of their existing subscription.
| Tier | Locations | Price per location |
|---|---|---|
| Starter | 1-10 | €15/month |
| Growth | 11-50 | €12/month |
| Scale | 51-250 | €9/month |
| Enterprise | 251+ | €7/month |
Revenue driver: Each new country increases the addressable ISV market (POS providers operating in that country) and retention (ISVs are less likely to churn if we cover all their markets). Revenue scales with ISV count × their location count, not with transaction volume or per-country pricing.
What matters for prioritization:
- Market size = number of businesses requiring fiscalization (drives location count per ISV)
- ISV overlap = how many ISVs operate in multiple countries we cover (network effect)
- Certification cost = our upfront investment per country
- Dev cost = engineering time to add the adapter

Revenue Math (Flat Fee Model)
Revenue doesn't come from individual countries — it comes from ISV subscriptions.
Example ISV: A POS provider with 500 locations across 3 countries.
500 locations × €9/mo (Scale tier) = €4,500/month = €54,000/year
Adding Germany doesn't change their bill. But if we don't support Germany and a competitor does, they leave.
The real multiplier: Each new country increases:
- Addressable ISVs — more POS providers can use Zyntem
- Retention — ISVs operating in 5+ countries we cover won't switch
- Location count per ISV — ISVs expand into new countries using us
Break-even per country: At average €9/location/month, each country needs to contribute enough new locations (directly or via ISV retention) to justify dev + cert cost:
| Investment | Months to break-even at... |
|---|---|
| 100 new locations | |
| €50K (cheap adapter) | 56 months |
| €100K (typical adapter) | 112 months |
| €300K (complex adapter) | 334 months |
Key insight: No single country justifies a €300K adapter on direct revenue alone. The value is in the network effect — covering Germany + Austria + Croatia + Slovenia together converts ISVs who need all four. The bundle sells; individual countries don't.
Deployment Mode Compatibility
Not all countries work with a pure Cloud API. Countries that require local signing, hardware security modules, or certified on-premise devices need the Embedded Local SDK — or are Cloud-incompatible entirely.
| Mode | Meaning |
|---|---|
| Cloud OK | Signing happens server-side, no local crypto required. Pure Cloud API works. |
| Embedded Required | Per-transaction signing with local certificates/keys. Must use Embedded SDK. |
| Hardware Required | Requires certified physical device (TSE, control unit, FDM). Neither Cloud nor Embedded alone works — need device integration. |
Per-Country Breakdown
| Country | System | Cloud OK? | Embedded OK? | Hardware? | Why |
|---|---|---|---|---|---|
| Germany | TSE | No | No | Yes | BSI-certified TSE device required per transaction. Cloud TSE (fiskaly) abstracts this but is still a "device" — we'd integrate via their API, not sign ourselves. |
| Spain | Verifactu | Yes | Yes | No | SHA-256 hash chain, no local device required. Server-side or local signing both work. |
| Spain | SII | Yes | Yes | No | Mutual TLS with FNMT cert. Cloud server can hold the cert and submit. |
| Spain | TicketBAI | Yes | Yes | No | XAdES signing with qualified cert. Cloud or local both viable. |
| Hungary | NAV Online | Yes | Yes | No | REST API with token auth. No local signing. Ideal for Cloud. |
| Austria | RKSV | No | Partial | Yes | Requires certified signature creation device (HSM/card/cloud). Cloud TSE providers (fiskaly SIGN AT) abstract this. Similar to Germany. |
| Slovenia | FURS | Yes | Yes | No | SOAP/XML with digital cert from SI-TRUST. Cloud server can hold cert. |
| Croatia | CIS | Yes | Yes | No | SOAP/XML with FINA digital cert. Cloud or Embedded. |
| Poland | Online Fiscal | No | No | Yes | Requires government-certified cash register (hardware or virtual). Virtual registers exist but need certification. |
| Portugal | SAF-T/ATCUD | Yes | Yes | No | RSA signing with AT-certified software. Cloud or local. |
| France | NF525 | No | Yes | No | Local signing chain mandatory (ECDSA P-256). Each register maintains its own chain in-process. Cloud breaks the per-register chain model. |
| Italy | SDI (B2B) | Yes | Yes | No | REST API with channel auth. No local signing required. |
| Italy | DC/SSW (B2C) | No | Yes | No | Requires QTSP electronic seal certificate. Local signing with eIDAS seal. Cloud could work if seal is server-hosted, but regulatory intent is local. |
| Greece | myDATA | Yes | Yes | No | REST API. Cloud-first design. |
| Denmark | SAF-T | Yes | Yes | No | File-based reporting, no per-transaction signing. |
| Norway | Cash Register | No | Partial | Yes | Requires certified control unit (similar to Sweden). Partnership-only. |
| Sweden | Control Unit | No | No | Yes | Certified control unit hardware required. Cloud providers (efsta) abstract this. |
| Belgium | GKS/FDM | No | No | Yes | Government-certified Fiscal Data Module hardware required. |
| Romania | Hardware Fiscal | No | No | Yes | Hardware fiscal device mandatory. API integration only for relay. |
| Slovakia | eKasa | Yes | Yes | No | Online API to Financial Directorate. Cloud or local. |
| Finland | eKutti | Yes | Yes | No | Voluntary, no signing. Cloud trivial. |
| Ukraine | Software Cash Register | Yes | Yes | No | Online API. Cloud OK. |
| Lithuania | Fiscalization | No | Partial | Yes | Joint certification with hardware vendor required. |
| Albania | Fiscalization | Yes | Yes | No | Online API with certified POS. |
| Moldova | MEV | Unclear | Unclear | Possible | ECC certification needed, details sparse. |
Summary
| Deployment Mode | Countries | Count |
|---|---|---|
| Cloud OK | Spain (all 3), Hungary, Slovenia, Croatia, Portugal, Italy SDI, Greece, Denmark, Slovakia, Finland, Ukraine, Albania | 14 |
| Embedded Required (Cloud won't work) | France NF525, Italy DC/SSW | 2 |
| Hardware Required | Germany TSE, Austria RKSV, Poland, Sweden, Norway, Belgium, Romania, Lithuania | 8 |
Key takeaway: 14 of 24 markets work with Cloud API. France and Italy B2C specifically require Embedded Local. 8 markets require hardware device integration (which is a third category — neither our Cloud nor Embedded SDK, but integration with a certified device provider's API like fiskaly).
Product implication: Our biggest market opportunity (Germany, 95 priority score) requires hardware device integration, not our SDK at all. The Cloud API covers the most markets. Embedded Local is specifically needed for France NF525 and Italy DC/SSW — two markets we already support.
Key Insights
The value is in the bundle. No single country justifies its dev cost on direct location revenue alone at €7-15/month per location. The network effect — covering a cluster of countries that ISVs need together — is what converts and retains customers.
Prioritize by ISV overlap, not by individual country size. Germany + Austria + Slovakia is more valuable than Germany alone because the same ISVs operate across all three.
13 of the top 18 markets cost under €5K to certify. The four countries we built first (France, Spain, Italy, Portugal) include two of the most expensive paths. Expanding to zero-cert markets (Germany, Hungary) adds the most ISV value per euro invested.
14 of 24 markets work with Cloud API — but the highest-priority market (Germany) requires hardware device integration. Consider a third product tier: device integration partnerships (fiskaly, efsta) alongside Cloud API and Embedded Local.
