The Best ERP for Greek Ecommerce Brands in 2026

What an ERP Does for a Greek Ecommerce Brand

A founder we talked to found this out at 11pm on a Black Friday: Skroutz had sold her best-selling item three times over, because the spreadsheet tracking stock was two hours behind reality. She spent the next morning writing apology emails instead of packing orders.

That's the failure mode an ERP exists to prevent. The right one for a Greek ecommerce brand comes down to what you sell, where, and how you handle MyData.

Ecommerce-first brands fit a purpose-built platform like Prim.io best. Accounting-led shops lean toward local systems like Soft1 or PYLON, and larger export groups look toward international platforms like Dynamics 365 Business Central or NetSuite.

Strip away the jargon and an ERP is one platform running orders, inventory, fulfillment, finance, and reporting on the same live data, so nobody's copying numbers between a webshop and a separate accounting tool by hand. For the fuller version, here's what an ERP system is.

What makes Greece different is the layer most generic ERP guides skip, and this one focuses exactly on how to pick the best ERP for Greek e-commerce brands.

MyData: The Compliance Filter That Shapes Your Shortlist

MyData is AADE's real-time digital bookkeeping and e-invoicing platform, and it's the first filter any ERP has to pass. Every invoice is validated and returned with a MARK, a unique registration number that has to appear on the document before it counts. No MARK, no valid invoice, whatever your own books say.

Under Greece's Law 5222/2025 e-invoicing rules, structured B2B e-invoicing built to the EN 16931 standard became mandatory in phases.

Large businesses over €1 million in 2023 revenue started March 2, 2026, a date already pushed back once, with a grace window through May 3 for parallel systems. Everyone else follows October 1, with the same kind of grace period through year end.

Missing it costs real money. MyData non-compliance penalties reach 10% of net value per missing document, capped at €250 a day and €100,000 a year, and repeat violations double or quadruple from there.

The commercial risk bites harder than the fine, though. Without that MARK, invoices are invalid for VAT deduction, so your buyer can't reclaim the VAT on your own invoice, and that kind of thing ends a client relationship fast, fine or no fine.

There's a format rule too, and it's easy to miss. Since January 1, 2024, any QR code invoice requirement applies to invoices issued through accounting or ERP software, linking straight back to AADE's verification page so anyone can scan it and confirm the invoice was actually registered.

Whatever ERP you're shortlisting has to transmit to MyData, natively or through a certified local connector.

Confirm that specifically for your legal entity before signing, since group-level certification doesn't always cover every subsidiary the same way.

We've seen brands assume a parent company's certification carried over, only to find their new subsidiary wasn't actually covered.

The Features a Greek Ecommerce ERP Must Have

Strong ecommerce ERPs share a core set of features tied to the order-to-fulfillment lifecycle you already run every day. Score any vendor against the work your team actually does, not the demo.

A gap anywhere on this list becomes a manual workaround right when volume makes it painful.

The Best ERP for Greek Ecommerce Brands: Top Options

We ranked these on MyData fit, ecommerce integration depth, size fit, deployment, and price, opening with the ecommerce-first choice and moving through established Greek and international platforms.

Greek accounting software is really a two-horse race, Epsilon Net Group on one side and ENTERSOFTONE on the other, so most local options below trace back to one of those two groups. The table shows how each system positions on the factors that decide most shortlists.

Local vendors win on native MyData because they're built around it from day one; ecommerce-first and international options compete on integration depth and scale instead. Use the table to narrow fast, then read the notes below.

1. Prim.io: Best for Greek & EU Multichannel Ecommerce Brands

Prim.io is purpose-built for brands and retailers, running orders, inventory, fulfillment, finance, and BI on shared live data, with go-live in around six weeks and Shopify as a ready-made integration.

• Pros: 50+ native integrations and a documented Shopify connector mean less custom build work, and 3.1M+ orders handled monthly is real evidence the platform holds up under volume.
• Cons: Prim.io doesn't publish its own MyData certification the way Greek-built systems do, so get that confirmed in writing for your legal entity before signing.

2. ENTERSOFTONE EBS ERP: Best for Growing Greek Ecommerce & Omnichannel Businesses

ENTERSOFTONE EBS is the Entersoft Business Suite, born from the 2025 Entersoft-SOFTONE merger. The combined group serves 90,000+ customers across Greece, Cyprus, Bulgaria, and Romania, and Hg Capital just agreed to a majority stake valued north of €1 billion, the largest software deal Greece has seen. Its myDATA API integration has run since the platform's 2020 launch, years before the mandate made it urgent.

• Pros: a MyData connection with six years of production use behind it, plus the combined group now covers ERP, CRM, HCM, WMS, and ecommerce under one roof.
• Cons: that breadth means ecommerce-specific flows often need partner configuration to work the way a purpose-built system would.

3. Epsilon Net PYLON ERP: Best for Greek Retail & Ecommerce Businesses

PYLON comes from Epsilon SingularLogic, the Epsilon Net Group's tech arm, and it's genuinely the flagship here: over 20,000 installations among Greek SMBs that want books and store on one system. Native MyData is the reason the product exists in its current form.

• Pros: 20,000+ installations is a real track record, and the group offers multiple entry points, including a browser-based version for teams that don't want local installs.
• Cons: the accounting-first heritage shows: ecommerce sync depends on add-ons rather than a native commerce core.

4. Galaxy Enterprise Suite: Best for Mid-Market & Complex Ecommerce Operations

Galaxy is Epsilon SingularLogic's other product, for larger operations once PYLON stops being enough. Same group, same MyData handling, but with real depth in HR, project management, and supply chain that most mid-sized retailers don't need yet.

• Pros: genuine enterprise depth, including track-and-trace and multi-warehouse logistics used by real Greek manufacturers, not just retailers.
• Cons: that depth is overkill for a small ecommerce brand, and you'll feel it in setup time before you feel the benefit.

5. Megasoft PRISMA Win: Best for Small & Mid-Sized Greek Ecommerce Businesses

PRISMA Win is long-established Greek commercial software built to Greek law from the start, with e-invoicing, basic ecommerce tools, a cloud option, and barcode and warehouse tools aimed at smaller retailers rather than large chains.

• Pros: 28 years in the Greek market, plus a lighter edition built specifically for fast, simple MyData compliance if that's genuinely all you need.
• Cons: ecommerce is explicitly an add-on module here, not a native design, so multichannel sync stays limited.

6. ALTEC Atlantis ERP: Best for Large Greek Commercial & Distribution Businesses

Atlantis, sold as Unisoft Atlantis, is ALTEC's open, modular system for large commercial and industrial companies and the groups that own several of them. An Entry edition scales it down for smaller firms, delivered through certified local partners.

• Pros: three Entry tiers let a growing business start light and scale up, and mobile apps for field sales are a genuine differentiator for distribution-heavy operations.
• Cons: nothing ALTEC publishes points to native ecommerce sync, so multichannel work runs through the partner, not the vendor.

7. Odoo: Best for Flexible & Customizable Ecommerce Operations

Odoo is open-source and modular, with a genuinely low entry price since you start with one module and expand later. What's easy to miss: Odoo now ships an official Greek myDATA e-invoicing module, l10n_gr_edi, in its own core codebase, not just the community localization repo.

• Pros: that official module is a stronger MyData foundation than "third-party add-on" suggests, and the low entry price lets you grow into the system rather than paying upfront.
• Cons: real ecommerce depth still needs a partner or an in-house developer to configure well.

8. Microsoft Dynamics 365 Business Central: Best for Growing International Businesses

Business Central is Microsoft's mid-market ERP, delivered in Greece through local partners, with MyData via a certified localization app. Strong fit for export-oriented firms already running subsidiaries abroad.

• Pros: real competition among localization vendors on Microsoft's own AppSource, including one from Data Communication, part of the Epsilon Net Group.
• Cons: Greek availability runs through a Cloud Solution Provider partner rather than a direct Microsoft signup, a step most other options skip.

9. SAP Business One: Best for Established Ecommerce Businesses

SAP Business One serves the upper SME bracket in Greece, and the detail worth knowing is who implements it: Epsilon SingularLogic has been SAP's certified partner since 2001, even while selling its own competing Galaxy suite. MyData runs through that partner relationship, not natively.

• Pros: a 24-year certified partnership is a genuinely long track record, backed by SAP's global ecosystem for firms that outgrew lighter tools.
• Cons: that same partner sells a competing product under the same roof, so ask directly which one they'd actually recommend.

10. Oracle NetSuite: Best for Cloud-First and International Ecommerce Groups

NetSuite is a cloud ERP for larger, international brands and groups, and its real strength is multi-entity consolidation, seeing every subsidiary's numbers in one place without a manual roll-up. MyData needs a certified third-party connector, and it sits in a higher cost tier than most of this list.

• Pros: multi-entity consolidation built for groups running several markets and currencies at once, a real gap in the Greek-built options above.
• Cons: we couldn't independently verify a specific named MyData connector, so get one named and demoed with your own invoices before you commit.

Which ERP Fits Your Business Size and Model

Match your profile to a starting shortlist, and treat the alternative as your fallback if the first choice doesn't fit once you see a demo.

The pattern holds up: local vendors anchor the smaller, accounting-led profiles, and international suites fit exporters and groups. For fast-growing, multi-channel brands that want ecommerce-first workflows rather than accounting software with ecommerce bolted on, Prim.io is the first stop.

What an ERP Costs in Greece

ERP pricing in Greece spans a wide band: open-source and SME tools sit at the low end, enterprise and international platforms sit at the top, and the gap is bigger than most first-time buyers expect.

The sticker price is only part of the bill: implementation, MyData connectors, integrations, training, and yearly maintenance often add up to more than the license itself.

Judge total cost of ownership across three years, since the first month's price understates the real bill. You can compare ERP costs before you commit; starting from transparent ERP pricing beats an open-ended consulting quote.

Signs Your Greek Ecommerce Brand Is Ready for an ERP

A few signals tell you it's time, usually together: selling on more than one channel, overselling stock, reconciling spreadsheets by hand, reporting lagging days behind.

The 2026 MyData deadlines add pressure on top of that. There's still room to grow into this too: Eurostat found that in 2025, ERP adoption among small firms across the EU ran from 41.08% of small enterprises to 88.71% of large ones, a gap that mostly reflects smaller firms not having made the jump yet.

Public money is actively lowering that barrier in Greece. The U.S. International Trade Administration notes that Greece 2.0 digitalization funding includes a $467 million investment in SME digitalization alone. That matters because SMEs in Greece account for 99.9% of enterprises and employ nearly 87% of the workforce, per the Hellenic Statistical Authority's 2024 figures, so this isn't a niche problem.

If you run a single store with low volume and simple books, hold off. A tidy spreadsheet and your accountant's MyData tool can carry you until volume actually grows.

How to Choose an ERP Vendor in Greece

Turn the shortlist into a decision with a short check: confirm MyData certification with API and SLA proof in writing, and require a Greek-language interface and a local partner.

Then pressure-test the fit: ask for references in your sector, and audit integrations at the transaction level by watching a real order move end to end.

Finally, compare total cost of ownership across three years, not one, and re-check compliance every time AADE changes its spec.

Frequently Asked Questions

Which ERP Is Best for a Greek Ecommerce Business?

It depends on size and channels: ecommerce-first brands fit Prim.io, accounting-led shops fit PYLON, and international groups fit Dynamics 365 or NetSuite.

What Is MyData and Why Does My ERP Need to Support It?

MyData is AADE's real-time digital bookkeeping and e-invoicing platform. Your ERP has to transmit invoice data natively or through a certified connector, or the invoices aren't valid.

What Are the 2026 Greek B2B E-Invoicing Deadlines?

Under Law 5222/2025, Phase A started March 2, 2026 for large businesses over €1 million in 2023 revenue, with a grace window through May 3. Phase B follows October 1 for everyone else, with a similar grace period through year end.

Can an ERP Connect to Shopify or WooCommerce?

Yes, most ERPs connect through native connectors or an API, and Prim.io offers 50+ native integrations plus a full REST API for anything that needs a custom link.

Do Small Ecommerce Businesses in Greece Need an ERP?

Not always. A single-channel store with low volume can manage on a spreadsheet and an accountant's MyData tool until order volume grows past that.

Conclusion

Ten systems, one real split: local Greek platforms built MyData in from day one, and ecommerce-first platforms built the multichannel workflow in from day one. Most Greek ecommerce brands need both, and that's a harder combination to find than it sounds.

Of everything on this list, Prim.io is the one built for exactly that combination.

It runs orders, inventory, fulfillment, and finance for brands and retailers specifically, not a generic business suite with ecommerce bolted on afterward, and it goes live in around six weeks instead of the months a local accounting-first system or an international enterprise suite usually takes.

For a brand selling through a webshop, Skroutz, and wholesale all at once, that's the difference between running one system and stitching together three.

Start With a Platform Built for Brands

Prim.io is the ERP built for brands and retailers, with ecommerce workflows ready out of the box rather than bolted on. See the platform and book a demo to map it against your channels and your MyData setup.
