In this practical case-study presentation, Dimitar Dimitrov from Stenik and Lyubomir Boyanov from JOYA.BG shared the real story behind one of the company’s largest digital transformations – migrating three core systems while simultaneously launching three new online stores. The lecture focused on the operational, organizational, and strategic lessons learned during a complex migration process involving ERP modernization, eCommerce restructuring, rebranding, and B2B transformation.

A Large-Scale Transformation with Significant Business Risk

The speakers opened the lecture by explaining that:
JOYA is not a startup,
but a long-established Bulgarian company with over 32 years of market presence, representing more than 50 international brands in categories such as:

• office supplies
• school products
• kids products
• and art materials.

The company serves:

• small businesses
• enterprise clients
• wholesalers
• and B2C customers.

Because of this scale,
the decision to migrate core systems carried:

major operational and financial risk.

The Old Infrastructure Had Become Too Complex

The original setup included:

• two separate online stores
• Microsoft Navision ERP
• and a PIM (Product Information Management) system.

Although functional,
the architecture had gradually become:

• overly complex
• difficult to maintain
• and operationally inefficient.

According to the lecture,
the company faced multiple problems:

• slow website performance
• outdated Magento infrastructure
• complicated ERP synchronization
• fragmented business logic
• and difficult management processes.

Some pages reportedly loaded in:

up to 10 seconds,

creating serious user experience and performance issues.

The team concluded that:
the complexity of the architecture itself had become one of the company’s biggest operational barriers.

Sometimes the Simplest Solution Is the Best One

A central theme of the lecture was:

simplification.

The speakers referenced the principle of:

Occam’s Razor,

arguing that:
the simplest effective solution is often the correct one.

Instead of continuously patching the old infrastructure,
the company decided on:

• a completely fresh start
• a new ERP system
• a simplified architecture
• a rebranding strategy
• and separate storefronts for different customer segments.

This included:

• migrating from Navision to Microsoft Dynamics 365
• rebuilding the eCommerce structure
• and separating business models more clearly.

Business Models Must Match the User Experience

One important insight from the lecture was that:
different customer groups require fundamentally different purchasing experiences.

The old setup attempted to combine multiple business models inside a single interface,
which created confusion and operational inefficiencies.

The new structure introduced:

• a dedicated B2C storefront
• a separate wholesale platform
• and a dedicated corporate portal for enterprise customers.

The speakers emphasized that:

B2B is not one single audience.

Enterprise procurement users,
wholesale buyers,
and traditional consumers all have:

• different workflows
• different expectations
• and different purchasing logic.

The Company Adapted Processes to the ERP – Not the Other Way Around

One of the most important strategic decisions was:

avoiding excessive ERP customization.

In the previous system,
JOYA had heavily customized processes around the ERP,
which created:

• maintenance problems
• upgrade difficulties
• and long-term technical debt.

This time,
the company intentionally adapted its internal workflows to fit the default logic of Dynamics 365 whenever possible.

According to the speakers:
this dramatically improved:

• scalability
• maintainability
• and future upgrade flexibility.

Modern B2B Commerce Is Becoming Self-Service

The lecture also explored how B2B platforms are evolving toward:

self-service ecosystems.

The new platform introduced features allowing corporate clients to:

• manage internal users
• assign permissions
• create approval structures
• and organize procurement workflows independently.

This reduced administrative workload for JOYA while improving customer flexibility and operational efficiency.

The speakers described this as:

the future of B2B eCommerce.

Procurement Control Was a Key Enterprise Requirement

A major challenge addressed during the migration was:

procurement governance.

Large enterprise clients often need:

• manager approvals
• spending controls
• and contracted pricing logic.

The platform therefore introduced:
approval flows for purchases outside contracted product lists,
helping clients reduce:

“maverick spending”

– unauthorized or uncontrolled purchasing behavior.

According to the speakers,
this feature was critical for winning and retaining enterprise customers.

Personalized Pricing Strengthens Loyalty

Another important feature was:

personalized price lists.

Corporate users could view:

• negotiated prices
• custom catalogs
• and organization-specific purchasing terms directly within the platform.

The speakers emphasized that:
this approach may reduce short-term revenue opportunities,
but significantly improves:

• loyalty
• customer retention
• and long-term partnerships.

Lesson 1: Involve the Right People Early

The first major lesson shared during the lecture was:

involve stakeholders from the very beginning.

The speakers stressed that:
successful transformations require participation from:

• operational teams
• daily system users
• management
• and technical partners.

Without early involvement,
organizations risk:

• resistance
• misalignment
• and costly implementation mistakes.

Lesson 2: Discipline Is Critical

Another core lesson was:

discipline throughout the transformation process.

The migration required:

• long-term coordination
• structured execution
• and alignment between teams and partners.

The speakers explained that:
without organizational discipline,
even technically strong projects can fail.

Lesson 3: Strong Partnerships Matter

The final key lesson focused on:

choosing the right long-term partners.

The presentation emphasized that:
major digital transformations are not purely technical projects,
but strategic business initiatives requiring:

• trust
• collaboration
• transparency
• and long-term alignment.

According to the speakers:
technology alone does not guarantee success –
execution quality and partnership quality matter equally.
