 DELIVERABLE 2: Moj-eRacun Deep-Dive 
 Company: ELEKTRONICKI RACUNI d.o.o., Zagreb
Website: https://portal.moj-eracun.hr
OIB: 42889250808 | Phone: +38517777810
Status: Officially certified posrednik | "Najkorišteniji posrednik u Hrvatskoj" 
 SERVICES: eRacun sending/receiving (B2B, B2G, B2C), Fiscalization 2.0, eArchive (11yr), DMS 
 API STATUS: NOT publicly documented. Available on-request to registered partners.
Developer portal (kreirajapp.moj-eracun.hr) exists but requires registration.
developer.moj-eracun.hr redirects to main portal — no separate dev docs found.
API type (REST/SOAP) UNCONFIRMED — requires direct contact. 
 PRICING: "Paket po mjeri" (custom packages only). Receiving is FREE. Sending = custom pricing.
For Bilko volume (250-10,000 invoices/month): negotiated — no published tiers. 
 KEY FACT FOR BILKO: Bilko does NOT need Croatian d.o.o. to call Moj-eRacun API.
Bilko (Norwegian company) calls their API. Moj-eRacun holds the posrednik cert. 
 Partnership contact: prodajna-podrska@moj-eracun.hr / +38517777810 
 
 DELIVERABLE 3: Sveracun (PostLink d.o.o.) — CONFIRMED PRICING 
 Company: PostLink d.o.o. | Address: Jurisiceva 13, Zagreb 10000
Website: https://www.sveracun.hr | OIB: 53625326797
Phone: +385 1 410 1130 | Email: info@sveracun.hr
Status: Officially certified posrednik 
 CONFIRMED PREPAID PRICING (source: https://www.sveracun.hr/cjenik, verified 2026-05-10):
No monthly minimum. Bundles valid 1 year. Includes send+receive+fiscalize+report+archive. 
 MINI: 120 invoices/year = 54.00 EUR excl. VAT (0.45 EUR/invoice)
PLUS: 360 invoices/year = 144.00 EUR excl. VAT (0.40 EUR/invoice)
PRO: 720 invoices/year = 259.20 EUR excl. VAT (0.36 EUR/invoice)
MAX: 1200 invoices/year = 408.00 EUR excl. VAT (0.34 EUR/invoice) 
 API: Available on-request ("API dokumentacija dostupna je na zahtjev") 
 TECHNICAL MODEL (confirmed from Sveracun website):
"Sve sto vam je potrebno je: a) aktivna registracija, b) F1 certifikat, c) ovlastenje za
fiskalizaciju u FiskAplikaciji."
= Customer holds their own F1 cert. Customer grants authorization to Sveracun in FiskAplikacija.
Sveracun then submits invoices on behalf of customer. Standard Croatian model. 
 
 DELIVERABLE 4: Path C Feasibility (Italy SDI-Style) 
 ITALY SDI vs CROATIA COMPARISON: 
 Italy: Intermediary accreditation OPTIONAL. Any software can send via SDI if technically
compliant. Software houses commonly hold delegated signing rights. No mandatory cert list. 
 Croatia: 34 state-certified posrednici (mandatory registration). Regulated under cybersecurity
law (NIS2 equivalent — "kljucni subjekti"). Strict cert custody rules. 
 CRITICAL FINA RULING (source: https://www.fina.hr/poslovni-digitalni-certifikati/poslovni-certifikati-za-fiskalizaciju):
"Certifikat moze zatraziti obveznik fiskalizacije. Informaticka tvrtka koja implementira sustav
fiskalizacije NE MOZE umjesto obveznika zatraziti certifikat."
= The FINA fiscal certificate can ONLY be requested by the taxpayer. Bilko CANNOT request it. 
 PATH C REALITY: 
 
 Customer holds FINA F1 cert (software cert, no hardware USB required) 
 Customer registers in FiskAplikacija and grants ovlastenje to chosen posrednik 
 Posrednik fiscalizes using customer's OIB + their certified platform 
 Bilko generates UBL XML: YES feasible 
 Customer signs with their own cert: YES 
 Customer submits via MIKROeRACUN (free govt app): YES 
 Bilko holds or manages certs: NO (FINA prohibition) 
 Bilko submits without being certified posrednik: NO 
 
 BILKO-SPECIFIC PATH C BLOCKERS: 
 
 ZKI generation requires OIB in plaintext — L4-A encrypted per security policy; audit exception needed 
 MD5 in ZKI prohibited per DATA-ENCRYPTION-POLICY.md line 222 — architectural exception required 
 Customer FiskAplikacija setup is per-customer manual burden 
 No Balkan SaaS vendor precedent for Path C found 
 
 PATH C CONCLUSION: Legally possible as tool, but cannot submit without routing through posrednik.
Path C effectively becomes Path B with more customer burden and no reduction in complexity. 
 
 DELIVERABLE 5: Croatian d.o.o. Incorporation Cost + Timeline (Path A Only) 
 Sources: Croatian START portal (start.gov.hr), FINA, secondary agency data. 
 COST BREAKDOWN: 
 
 Minimum share capital: 2,654.46 EUR (HRK 20,000 equivalent, since 2013) 
 Court registration fee: 350-500 EUR 
 Notary fees (foreign founders): 500-1,500 EUR 
 Attorney/agent fee: 1,500-3,000 EUR 
 OIB assignment: Free 
 FINA fiscal cert per customer: ~70-150 EUR / 5yr period (estimate)
TOTAL INCORPORATION: 4,500-8,000 EUR one-time 
 
 ANNUAL ONGOING: 
 
 Croatian bookkeeper/accountant: 150-400 EUR/month (legally required for RGFI filings) 
 Corporate tax: 10% if revenue under 1M EUR; 18% above 
 VAT mandatory threshold: 60,000 EUR turnover 
 
 TIMELINE: 
 
 Croatian citizens via START: 2-3 business days (requires Croatian e-ID — NOT available to ALAI) 
 Foreign founders: 30-60 business days via court — requires notarized POA, apostille, Croatian translation 
 OIB assignment: 1-3 days after court registration 
 Posrednik certification AFTER d.o.o.: Additional 60-120 days (Porezna uprava evaluation + NIS2 compliance)
TOTAL PATH A TIMELINE: 6-12 months minimum from today (2026-05-10)

 RECOMMENDATION: PATH B — Partner Integration 
 PRIMARY PARTNER: Sveracun (PostLink d.o.o.) 
 
 Only partner with PUBLICLY CONFIRMED per-invoice pricing: 0.34-0.45 EUR/invoice 
 API on-request 
 Transparent pricing for Bilko to build reseller margin 
 Contact: info@sveracun.hr / +385 1 410 1130 
 
 SECONDARY PARTNER: Moj-eRacun (ELEKTRONICKI RACUNI d.o.o.) 
 
 Largest market presence in Croatia ("najkorišteniji posrednik") 
 Custom packages possible for SaaS resellers 
 Contact: +38517777810 
 
 TERTIARY (for multi-country scale): EDICOM or Fonoa Technologies 
 
 Both certified in Croatia and operate in multiple EU/Balkan markets 
 API-first; multilingual support 
 
 PER-DIMENSION RATIONALE:
Time: Path B = 60-90 days; Path A = 6-12 months
Cost: Path B = zero ALAI fixed; per-invoice passthrough with markup possible
Liability: Path B partner absorbs cert custody + 500,000 EUR fine exposure
Engineering: Path B = one API call/invoice; Path A = ZKI crypto + mTLS + cert KMS + outbox
Reusability: Partner model replicable in RS (SEF has certified operators); Path C ZKI also reusable
Control: Path C wins on autonomy but customer burden offsets at Bilko's early scale 
 
 OPEN QUESTIONS FOR DIRECT VENDOR CONTACT 
 
 Sveracun API: Multi-tenant model? REST or SOAP? Rate limits? Contact: info@sveracun.hr 
 Moj-eRacun: SaaS reseller/white-label terms? Volume pricing 250-10,000/month? +38517777810 
 EDICOM: Croatia reseller program pricing? REST API docs? +34961366565 
 APIS-IT: Is eRacun 2.0 REST or SOAP? Existing SOAP endpoint cistest.apis-it.hr:8449 is
Fiscalization 1.0 (B2C). eRacun 2.0 may use Peppol/AS4 for inter-posrednik or different endpoint.
Contact: fiskalizacija.help@apis-it.hr 
 Posrednik certification process (Path A only): Exact criteria, timeline, cost from Porezna uprava 
 ZKI in Path B: Does posrednik API compute ZKI server-side, or must Bilko generate locally? 
 
 
 BILKO CODEBASE: MINIMUM PATH B CHANGES 
 
 Replace Error throw at fisk/index.ts line 103 with posrednik API HTTP call 
 Add jir, fiskStatus fields to Invoice model in schema.prisma (currently absent) 
 Add HR equivalent of SEFSubmissionQueue (Serbia outbox pattern at lines 600-618) 
 Change FISKConfig.certificatePath: string to posrednik API credentials config 
 Fix getInvoiceStatus() returning 'pending' as terminal — poll posrednik for JIR 
 Remove/separate legacy SOAP endpoint cistest.apis-it.hr:8449 (Fiscalization 1.0, not 2.0) 
 Add UI: customer onboarding flow for FiskAplikacija authorization confirmation
