Greece has a distinctive ERP market that often surprises European IT directors evaluating it from the outside. The country has a strong domestic software industry, a long history of ERP adoption in manufacturing and distribution, and since 2026, one of the most demanding real-time e-invoicing mandates in Europe: MyData. The combination of a sophisticated local vendor ecosystem, a 40% ERP penetration gap (according to Epsilon Net Group analysis), and an imminent compliance deadline makes Greece both a challenging and an opportunity-rich market for ERP buyers.
This guide covers the ERP landscape in Greece in 2026: the two dominant local vendors, the international players with real footprint, the MyData technical requirements that non-negotiably filter the shortlist, and a recommendation matrix by company profile.
The Greek ERP Market at a Glance
A Market Shaped by Family-Owned SMEs
Greece’s business fabric is dominated by small and medium enterprises. Of the approximately 600,000 active businesses registered with AADE (the Greek independent tax authority), the vast majority are SMEs with fewer than 50 employees, often family-owned, concentrated in trade, food and beverage, hospitality, professional services, and construction.
This structure has consequences for ERP adoption. Purchasing decisions are frequently influenced by the company’s accountant or external bookkeeping firm rather than by an IT department. The accounting software ecosystem and the ERP ecosystem are more intertwined in Greece than in Germany or France. A new ERP entrant must not only convince the CTO or CFO but also the external accountant who runs the books.
The Greek ICT market is estimated at USD 8.72 billion in 2025, growing toward USD 9.79 billion in 2026, with software for SMEs advancing at approximately 10.72% CAGR through 2031, driven largely by e-invoicing compliance pressure (Greece ICT Market analysis, Mordor Intelligence, 2026).
Government Digitalization Push
The Greek government has allocated significant funding under the Greece 2.0 national recovery plan to accelerate SME digitalization: approximately USD 467 million in direct digitalization support for businesses, including voucher programs covering first-year costs for ERP, CRM, e-commerce, and accounting software. This subsidy layer is reducing the entry barrier for cloud ERP adoption among companies that previously relied entirely on local standalone accounting applications.
Key Sectors with Specific ERP Requirements
- Maritime and shipping: Greece operates the world’s largest fleet by tonnage. Shipping companies require ERP modules covering charter party management, flag state compliance, bunker accounting, and port agent billing. No generic ERP covers this out-of-the-box: certified maritime ISV overlays are required.
- Tourism and hospitality: Hotels, travel agencies, and tour operators need tight PMS/POS integration, seasonal staff management, and multi-currency billing.
- Food processing and distribution: Lot traceability, recipe management, cold chain logistics, and HACCP documentation.
- Construction: Project cost tracking, subcontractor management, and retention accounting under Greek civil construction law.
- Professional services and accountants: High volume of transactions, multi-client management, and accountant-centric workflows.
MyData: the Compliance Filter That Reshapes the Shortlist
Before reviewing any vendor, Greek ERP buyers must understand one hard constraint: if a vendor cannot transmit invoices to the MyData platform, it is not viable for a Greek entity. Full stop. MyData is not a feature, it is a regulatory operating condition.
MyData: What ERP Buyers in Greece Must Know
What MyData Is
MyData (My Digital Accounting and Tax Application) is the real-time digital bookkeeping platform operated by AADE, Greece’s Independent Authority for Public Revenue. Every Greek business must transmit a structured summary of each issued invoice to the MyData API within minutes of issuance. The platform acts as Greece’s central tax ledger: AADE can cross-check declared revenues, VAT, and expenses in real time rather than waiting for annual tax filings.
MyData was introduced in phases starting in 2021. The voluntary phase became mandatory for all businesses in January 2024 for data already subject to transmission obligations. Law 5222/2025 then elevated structured electronic invoicing itself — not just reporting — to a legal standard, turning Greece into one of the first EU member states with mandatory B2B e-invoicing. (Law 5222/2025 compliance guide, Zone & Co, 2025)
The 2026 Mandatory B2B E-Invoicing Timeline
Law 5222/2025 mandates structured B2B electronic invoicing in two phases:
- Phase A — March 2, 2026: mandatory for large businesses with gross revenues exceeding EUR 1 million in the 2023 tax year. A parallel transition period runs until May 3, 2026, during which companies may continue issuing traditional invoices alongside structured ones.
- Phase B — October 1, 2026: mandatory for all remaining businesses established in Greece. A further transition period until December 31, 2026 covers companies that need additional time to configure their ERP.
The invoice XML format follows EN 16931-1 (the European standard). Since January 1, 2024, all PDF invoices issued through MyData must include a QR code linking to the AADE verification page. Each transmitted document receives a unique MARK identifier from AADE that must be stored in the ERP record. (EDICOM, Greece Mandatory B2B E-Invoicing 2026)
ERP Technical Requirements for MyData Compliance
An ERP system must support five capabilities to operate legally in Greece:
- MyData API connector: direct REST API integration with the AADE MyData platform for real-time invoice transmission.
- Classification code mapping: mapping of each revenue account and product category to AADE classification codes (income category + VAT treatment + invoice type code).
- MARK storage: the unique registration number returned by AADE must be recorded and linked to each invoice in the ERP.
- QR code generation: PDF invoices must embed the AADE verification QR code.
- Exception handling: automatic error routing when AADE rejects a transmission, with retry logic and compliance audit trail.
ERP vendors without a certified MyData connector — or relying on manual exports to a third-party platform — create a daily operational risk and audit exposure.
Penalties for Non-Compliance
The penalty framework under Law 5073/2023 and Law 5222/2025 is structured as follows:
- Non-transmission: a fine equal to 10% of the net value of each non-transmitted invoice, capped at EUR 250 per day and EUR 100,000 per tax year.
- Late transmission: 50% of the non-transmission penalty, applied when data is eventually submitted after the deadline.
- Repeated violations: if the same infringement is committed within 5 years of a prior fine, penalties are doubled; repeated violations within the same five-year window are quadrupled, up to EUR 100,000 per year.
- VAT invalidity: any invoice not registered in MyData is deemed invalid for VAT purposes. The buyer cannot legally claim input VAT credit, and the seller has not fulfilled its bookkeeping obligations. (Fiscal Solutions, New penalties for MyData non-compliance)
The VAT invalidity rule is the most commercially significant: a supplier whose ERP fails to transmit on time puts its clients’ VAT recoverability at risk — a powerful lever for buyers to mandate supplier compliance.
Local Greek ERP Vendors: the Market Leaders
ENTERSOFTONE: The National Champion
Formation: ENTERSOFTONE was established in 2025 through the strategic merger of Entersoft and SOFTONE, creating the largest provider of business software products and services in Greece. (ENTERSOFTONE, About)
Scale: more than 1,500 employees, 700+ partners across Greece and the region, over 90,000 customers in Greece, Cyprus, Bulgaria, and Romania, and more than 50,000 cloud (SaaS) installations.
Product portfolio: the merged entity offers ERP, CRM, HCM and payroll, accounting platforms (the SOFT1 series for SMEs, Entersoft Business Suite for mid-market), electronic invoicing, e-procurement (via cosmoONE), digital commerce, and warehouse management.
Market position: ENTERSOFTONE is the undisputed market leader in the Greek cloud-based business software market. The merger combined SOFTONE’s strength in SaaS ERP for SMEs (80,000+ businesses historically served through a 600+ channel partner network) with Entersoft’s depth in retail, distribution, manufacturing, and food and beverage.
MyData: deep MyData integration is native and central to the product, given that SOFTONE was one of the first Greek vendors to build a certified real-time transmission connector. Cloud clients benefit from automatic MARK storage and QR code generation without manual configuration.
Sectors: retail and distribution, manufacturing, food and beverage, hospitality, professional services, pharmaceuticals. Strong presence in franchise management and multi-site retail POS.
International reach: Romania, Bulgaria, Cyprus — the only local Greek ERP vendor with significant regional scale.
Profile fit: the default choice for a Greek company of any size wanting a locally developed, locally supported ERP with deep MyData compliance. Particularly strong for mid-market companies (20-300 employees) in distribution and manufacturing who want a single-vendor solution without the complexity of an international ERP rollout.
Epsilon Net Group (Epsilon SingularLogic): the Accountant’s ERP
Formation: Epsilon Net S.A. acquired SingularLogic in 2020, merging it with its existing accounting and tax software divisions. The combined group is now called Epsilon Net Group (operating under the brand Epsilon-SingularLogic for enterprise products).
Scale: 1,700+ employees, 500+ partner network across Greece. The group reports approximately 35% market share in commercial ERP software in Greece, while noting that 40% of the Greek market still operates without any ERP software — a structural opportunity for the sector. (Epsilon Net Group, company overview)
Products:
- PYLON Hybrid: the group’s flagship ERP positioned as an “Agentic AI ERP” for mid-market companies, supporting cloud and on-premise deployment.
- Galaxy Enterprise Suite (via SingularLogic): the established ERP for larger enterprises and corporate groups, covering finance, HR, supply chain, and project management.
- Epsilon accounting and tax platform: the dominant accounting software for Greek accountants and fiduciaries, installed at the vast majority of Greek accounting offices. This creates a massive installed base and prescriber network that feeds ERP upsell.
SAP relationship: SingularLogic (now Epsilon SingularLogic) is a certified SAP Value Added Reseller and Services Partner, as well as an SAP Partner Center of Expertise for support services. This means Epsilon can deploy and support SAP Business One alongside its own Galaxy platform for clients requiring SAP’s global ecosystem. (SingularLogic SAP partnership, portal.singularlogic.eu)
MyData: full MyData integration across PYLON and Galaxy product lines. The accounting software heritage means the group’s products have handled AADE data transmission requirements since the early phases of the mandate.
Profile fit: strong for Greek companies that use Epsilon accounting software and want to extend into full ERP without changing their accounting provider. Also a natural fit for companies requiring SAP Business One with local Greek support.
International ERP Vendors with Real Greek Footprint
Microsoft Dynamics 365 Business Central
Microsoft Dynamics 365 Business Central has a growing presence in the Greek mid-market, primarily through local implementation partners. The Greek partner ecosystem lists several certified resellers, with strong focus on manufacturing, logistics, and professional services.
MyData: Business Central deployments in Greece require a certified MyData localization app, implemented by local partners as part of the standard Greek deployment scope. Microsoft’s official Greece localization includes VAT management and AADE reporting capabilities.
Key partners: Step One Enterprise Solutions, Data Communication (part of Epsilon Net Group), and other Dynamics-specialized firms.
Profile fit: mid-market Greek companies (50-500 employees) wanting a Microsoft-native ecosystem, particularly those already running Microsoft 365 or Azure workloads. Strong in professional services and project-based businesses.
Odoo
Odoo has approximately seven certified partners in Greece, led by established Silver and Gold partners such as Existanze, Neurons Tech, Emity, and Methodoos IKE. (Odoo partner directory, Greece)
The Greek Odoo community has developed robust localization modules covering:
- Greek chart of accounts (ΕΓΛΣ)
- AADE MyData e-invoicing transmission
- Greek VAT declarations
- Intrastat reporting
Profile fit: Greek SMEs (5-100 employees) wanting an open, modular ERP at competitive cost. Ideal for companies with strong IT competency internally and preference for an integrator-led model with community-supported Greek localizations.
SAP
SAP’s enterprise products (S/4HANA, SAP Business One) have a presence in Greece primarily through large enterprise clients and through the SAP partnership maintained by Epsilon SingularLogic. Direct SAP deployments for large Greek industrial groups or multinationals with Greek subsidiaries are handled by international integrators (Deloitte, Accenture, PwC) with local presence.
Profile fit: large enterprises and multinational subsidiaries with Greek operations where a global ERP platform is mandated from corporate headquarters. SAP Business One, via Epsilon SingularLogic, reaches the upper SME bracket.
Oracle NetSuite
Oracle NetSuite has a specific niche in the Greek maritime and shipping sector, where it is deployed as a global financial management platform for ship-owning and ship-management companies, layered with certified maritime ISV solutions (crew management, voyage accounting, bunker management).
MyData: NetSuite deployments in Greece require a certified third-party MyData connector from an ISV, as Oracle does not natively ship a Greek localization with MyData support.
Profile fit: ship-owning groups and maritime service companies with global operations requiring a cloud-native financial platform alongside sector-specific maritime modules.

How to Choose an ERP in Greece: 5 Decision Criteria
1. MyData Certification — Non-Negotiable
Verify that the ERP vendor holds a certified MyData API connector registered with AADE. Check the following before signing any contract:
- Does the vendor have a direct REST API connector to the AADE MyData platform?
- Is MARK storage automated and linked to each invoice record?
- What is the SLA for resubmission in case of AADE transmission rejection?
- How are retroactive transmissions handled for invoices issued before the go-live date?
Vendors that route MyData transmission through an intermediary “middleware” add integration complexity and an additional failure point. Native integration is strongly preferable.
2. Greek Language and Local Partner Presence
An ERP with a Greek UI and extensive online documentation in Greek is a practical requirement for non-English-speaking accounting and operations staff. Equally important is a local implementation partner with Greek-speaking consultants, physical presence, and a track record of live Greek deployments. A reference list from the partner is the minimum due diligence step.
3. Sector Expertise
Greek sectors have highly specific process requirements. A retail chain running a franchise model needs POS integration and consignment stock management. A food manufacturer needs recipe-level cost tracking and HACCP documentation. A maritime company requires entirely different software beyond the financial ERP layer. Shortlist vendors who have at least ten live references in your sector, not generic functional coverage claims.
4. International Scalability
If your company operates subsidiaries in Cyprus, Bulgaria, Romania, or elsewhere in the EU, evaluate whether the chosen ERP can serve those entities in the same instance or via a consolidated reporting model. ENTERSOFTONE has natural coverage in Cyprus and the Balkans. Dynamics 365, Odoo, and SAP cover broader EU geographies with local legal entities.
5. Total Cost of Ownership Including Localization Maintenance
MyData is a living regulation: AADE updates its API specifications, adds new invoice types, and modifies classification codes over time. Every ERP deployment in Greece carries an ongoing localization maintenance obligation. Understand who is responsible for tracking AADE regulation updates, how quickly the vendor or partner releases certified updates, and what the additional maintenance cost is. For international ERP vendors, this localization maintenance is typically handled by the Greek partner, which may change over time.
Recommendation by Company Profile
Greek SME (1-20 employees, under EUR 2M revenue): Odoo Enterprise with a certified Greek localization partner, or ENTERSOFTONE SOFT1 cloud. Both offer MyData compliance at accessible price points. Odoo is cheaper at low user counts; SOFT1 comes with a larger local support network.
Mid-market Greek company (20-200 employees): ENTERSOFTONE Business Suite or Epsilon Net PYLON Hybrid. Both are deeply integrated with the Greek regulatory environment and carry a 700+ and 500+ partner networks respectively for local support. For companies already using Epsilon accounting software, PYLON is the natural upgrade path.
Multinational with a Greek subsidiary: Dynamics 365 Business Central or SAP Business One (via Epsilon SingularLogic) for alignment with the parent’s Microsoft or SAP ecosystem. Verify that the implementation partner has active Greek MyData connectors and is committed to maintaining AADE compliance updates.
Construction or engineering company: Dynamics 365 Business Central or ENTERSOFTONE — both have project accounting and subcontractor management capabilities. Verify references in Greek construction specifically, as Greek-specific contract retention rules require local configuration.
Maritime and ship-owning group: Oracle NetSuite or a maritime-specific ERP (MACS3, Amos, Helm CONNECT) with a certified third-party MyData connector and a local Greek ISV for AADE compliance. A generic ERP rarely covers the full operational maritime scope.
