“ Every Transition is an opportunity. “

Recent assessments by the European Commission, the ECB, and the European Parliament confirm that Bulgaria meets the convergence criteria and is on track to become the 21st euro area member.

For most businesses, this is not “just another New Year.” It’s a full-stack transformation touching prices, documents, contracts, integrations, analytics, and every line of code that assumes BGN as the primary currency.

The good news: SIX ERP is ready—and so are our customers.
Let’s walk through what the change means and how to approach the migration properly.

With euro introduction on 01.01.2026:

• EUR becomes the primary accounting and reporting currency for Bulgarian entities.
• BGN-denominated records do not disappear: historical data, documents, and reports remain in BGN with full legal validity.

Systems must:

• Apply the official irreversible conversion rate once it is set by EU Council decision.
• Respect rounding and consumer-protection rules, including preventing hidden price increases and supporting dual price display during the transition, as outlined in Bulgaria’s National Euro Changeover Plan and EU best practices.

In other words: this is a controlled, rules-driven transformation—not an ad-hoc “find & replace BGN with EUR” exercise.

Most companies already “support multiple currencies” in theory. In practice, they have one functional currency at the core—for Bulgaria, that’s been BGN.

On 01.01.2026 that core changes to EUR.

How painful or smooth this becomes depends entirely on how deeply your systems are integrated into real business processes:

• If your ERP is central (orders, invoicing, stock, production, projects, BI) → the impact is broad but manageable with the right tooling.
• If you use many disconnected tools + spreadsheets → the risk of inconsistencies, rounding errors, and audit issues rises sharply.

This is exactly the scenario SIX ERP is built for: one source of truth, coordinated changeover.

Below are the essential pillars every serious business system must handle. After each, you’ll see how SIX ERP addresses it.

3.1 Preservation of Historical Data

Requirement

All historical transactions, invoices, credit notes, payroll records, and reports in BGN must remain:

• Legally correct
• Technically accessible
• Auditable

How SIX ERP handles it

• Historical documents stay in their original currency (BGN) with all totals preserved.
• Reporting allows period-based views: pre-2026 in BGN, post-changeover in EUR, and consolidated analytics where needed.
• No destructive mass “overwriting” of history—only forward-looking changes based on the new legal tender.

3.2 Correct Conversion & Rounding

Requirement

• Use the official irreversible conversion rate (once adopted by EU legal act).
• Apply rounding rules consistently (typically to 2 decimal places) and transparently.
• Prevent “manual tweaks” that break consistency across modules.

How SIX ERP handles it

System-level configuration for:

• Official conversion rate (single source, applied everywhere)
• Standardized rounding logic for:
  • Item prices
  • Document lines
  • Totals
  • Ledger postings

Automated migration of:

• Item master prices
• Price lists
• Default currency settings
  from BGN → EUR with traceable logs.

3.3 Dual Display & Transitional Period

EU and national guidance for euro changeovers emphasizes:

• Dual price display (BGN and EUR) for a defined period before and after the changeover date.
• Clear communication to avoid hidden price increases and protect consumers.

How SIX ERP supports this

• Configurable dual display modes in:
  • Offers and invoices
  • POS/invoicing screens
  • Selected customer-facing documents

Ability to:

• Show base price in EUR
• Show reference in BGN (during the dual period) using the official rate, clearly labeled.

This helps your teams, auditors, and customers trace values with zero ambiguity.

3.4 Opening Balances & General Ledger

Requirement

• Accurate migration of:
  • Opening balances on 01.01.2026
  • Sub-ledger balances (customers, suppliers, fixed assets, inventory)
• No breaks in:
  • Trial balances
  • VAT and statutory reports
  • Management reporting

SIX ERP approach

Automated balance conversion tools:

• Take closing BGN balances at 31.12.2025
• Convert to EUR using the official rate
• Post clearly documented opening entries in EUR

Parallel validation reports:

• Before/after comparison in BGN & EUR equivalents
• Exceptions log for edge cases (legacy data, custom integrations)

3.5 Inventory & Pricing

This is one of the most sensitive areas.

Requirement

• All stock valuations, sales prices, purchase prices, and standard costs must:
• Convert consistently and
• Remain logically aligned with margins and contracts.

In SIX ERP

Automatic conversion of all inventory prices from BGN to EUR as of 01.01.2026.

Preservation of:

• Existing discount logic
• Price tiers
• Customer-specific agreements (recalculated to EUR).
• Optional “preview” mode in sandbox:

So you can validate margins, thresholds, and psychological price points before go-live.

3.6 Contracts, Documents & Templates

Requirement

Contracts, offers, frameworks, subscriptions, recurring invoices:

• Must reflect EUR from the effective date.
• May need dual display or annexes explaining the conversion.
• Legal texts and templates must be updated uniformly.

SIX ERP readiness

• Centralized document templates module:
• Enables batch updates to T&Cs, currency labels, and dual display.

Consistent handling across:

Offers, orders, invoices, credit notes, delivery notes, service contracts.

3.7 Integrations: Banks, PSPs, Accounting, BI

Requirement

Bank integrations, payment providers, accounting exports, and BI tools must:

• Switch to EUR where required
• Maintain mapping for historical BGN entries
• Avoid “currency mismatch” errors.

How SIX ERP solves this

Updated integrations for:

• EUR-based bank statements for Bulgarian IBANs
• Accounting exports aligned with EUR as main currency

BI layer:

• Handles mixed historical BGN and current EUR datasets
• Ensures KPIs and dashboards stay comparable across the changeover.

3.8 Testing, Training & Communication

Requirement

• No “big bang in production without rehearsal.”

Users must:

• Understand what changes in screens & reports
• Know how to explain EUR pricing to customers and partners.

You can frame your euro migration with these practical phases:

System & Process Audit

Identify every touchpoint where BGN is used: ERP, CRM, POS, WMS, BI, payroll, custom tools.

SIX ERP gives you a central map of currency usage across modules.

Define Conversion Policy

• Approve how you’ll handle:
  • Rounding
  • Dual display
  • Special price agreements

Configure this once in SIX ERP instead of per-system firefighting.

Prepare & Update

• Apply SIX ERP’s euro-readiness update before the effective date of 1.1.2026
• Enable dual display (where relevant).
• Update templates and legal texts centrally.

Train Users

• Short, focused sessions:
  • “What changes on 1 January 2026”
  • “How to interpret old BGN vs new EUR documents.”

Communicate Externally

• Inform customers, suppliers, partners:
  • No arbitrary price hikes
  • One official conversion rate
  • Transparent display of both currencies during the transition.

Go-Live & Monitor

At 01.01.2026, base currency is automatically switched to EUR in SIX ERP.
