ODOO · UNIFIED RETAIL OPERATIONS

A unified operational system for 20+ retail locations across museums and cultural venues.

How Ελληνικά Αναμνηστικά built a scalable retail operation across museums and cultural venues with Odoo Enterprise, integrated inventory, ESL, loyalty, and operational automation.

At a glance

According to its articles of incorporation, ΕΛΛΗΝΙΚΑ ΑΝΑΜΝΗΣΤΙΚΑ S.A. operates in the retail and wholesale trade of cultural products, including replicas of antiquities, artworks, jewelry, folk art objects, and handcrafted items connected to Greek cultural heritage and contemporary Greek creation. Its retail network includes locations such as the National Archaeological Museum, the Hellenic Parliament, the new Thessaloniki museum at Pavlou Mela, and the Archaeological Museum of Mystras.

As a new business designed from the beginning to operate across multiple museum and cultural venues, Ελληνικά Αναμνηστικά required an operational infrastructure capable of scaling alongside its growth, not a fragmented collection of applications that would become progressively harder to coordinate over time.

Neurons Tech designed and implemented a unified architecture first solution built on Odoo, covering point of sale, warehouse and inventory management, procurement, after sales support, loyalty, electronic shelf labels, and tax compliance as part of a single operational system rather than disconnected additions.

Our approach

OPA: Observe · Plan · Act

For this project, we applied the OPA framework (Observe · Plan · Act), the methodology we use for every serious operational transformation engagement: first the operational architecture is designed, then the technology that will support it is selected.

O

OBSERVE

As this was a newly established business, there was no existing operation to observe. There was an operational model that needed to be designed from the ground up.

We worked closely with management to understand how the network needed to function in practice:

how visitors would be served at the point of sale,
how inventory would move between warehouses and retail locations,
how pricing and shelf labels would be updated,
how inventory counts and reconciliations would be handled,
and how a unified operational view would be maintained across multiple retail locations.

At the same time, we mapped the specific operational requirements of the venues themselves — museums and cultural institutions with elevated expectations around service speed, aesthetic consistency, and operational reliability — alongside the regulatory framework governing tax flows and fiscal documentation.

This understanding phase ultimately shaped the overall architecture of the system

P

PLAN

The core architectural decision was made from the beginning: a unified Odoo Enterprise environment with a centralized product catalog, real time inventory visibility, and shared operational logic across all retail locations.

On top of this foundation, a fully integrated operational environment was progressively designed:

TAGORA ESL — a Greek developed electronic shelf label system and proprietary Neurons Tech product, fully synchronized with Odoo. Price changes automatically update shelf labels in real time without manual replacement.

Inventory with structured warehouse operations — unified inventory management, stock counts, and balancing processes providing reliable stock visibility across the entire retail network.

Purchase — organized procurement and supplier order management directly connected to inventory flows.

Helpdesk — structured after sales support operating inside the same operational environment.

Loyalty / membership card — integrated directly into the POS environment for customer recognition and repeat purchases across all locations.

Payment terminal integration — a fully integrated checkout experience designed to reduce operational errors and accelerate transaction completion.

NT Connect (myDATA / ΑΑΔΕ) — native tax compliance integrated directly into invoicing and fiscal document workflows.

The rollout itself was designed as a phased expansion from the beginning: first the initial retail location, followed by operational stabilization, and then gradual rollout across the rest of the network on the same architectural foundation.

A

ACT

Implementation began in June 2025, with the first retail location going live in August of the same year.

From that point onward, the architecture expanded progressively across each new location, with every rollout benefiting from the operational knowledge and improvements gained from the previous one.

Twelve months later, the network has scaled to more than 20 POS locations operating on a unified operational system, where each new rollout is now activated in a fraction of the time and complexity required for the initial deployment.

What was designed operationally

A unified operational foundation

Instead of building a retail network with disconnected applications, isolated data, and separate operational processes that would later need to be unified, a shared operational environment was designed for the entire network from the beginning. Products, pricing, inventory, tax flows, and daily operations all operate on the same architectural logic, providing centralized control and unified visibility across every retail location.

Pricing and shelf labels synchronized

With TAGORA ESL, electronic shelf labels were integrated directly into Odoo from the initial operational design. Every pricing change updates shelf labels automatically in real time, without manual replacement and without discrepancies between the POS system and the physical retail environment. The result is a more reliable customer experience and significantly lower operational overhead for store personnel.

Inventory architecture designed

Inventory management was structured from the beginning around a multi location retail model, controlled warehouse operations, and organized stock movement flows. Inventory counts, balancing, and stock transfers operate on a unified operational foundation, providing reliable availability visibility and controlled replenishment across the network. Each new location is onboarded onto already structured operational processes rather than ad hoc workflows that would later require redesign.

Integrated procurement and replenishment workflows

Purchase management was designed as an organic part of the overall architecture rather than an isolated back office process. Supplier orders are directly connected to real inventory requirements and retail operations, enabling more controlled planning and improved visibility into replenishment needs across the network.

After sales support and loyalty integrated into daily operations

After sales support and loyalty workflows were not added later as optional features. They were integrated from the beginning into the operational POS environment itself, enabling unified customer experience, customer recognition, and repeat purchase workflows across every retail location. Each new store operates on the same customer experience and the same operational logic.

Checkout designed for high visitor traffic

Payment terminal integration was embedded directly into the checkout flow with the goal of fast, stable, and reliable transaction completion. In environments such as museums and cultural venues, where visitor experience and service speed are critical, checkout reliability becomes part of the institution's operational image rather than a simple technical detail.

Tax compliance designed as part of the operational flow

With NT Connect, myDATA and ΑΑΔΕ flows were integrated directly into the operational architecture of the platform from the beginning. Tax compliance was not treated as a later addition or separate process, but as a native part of invoicing and transaction workflows, reducing manual intervention and operational friction.

Architecture designed to expand consistently

The most important outcome was not simply the successful launch of the initial locations, but the creation of an operational architecture capable of expanding consistently over time. Every new retail location is now deployed on an already proven operational foundation, with significantly lower implementation time, reduced complexity, and much greater predictability compared to the original rollout.
