Shocking statistic: The average Bulgarian online store loses 8.3 hours per week only for manually updating prices in both currencies. With 50 employees this means 2,160 hours per year or 43,200 leva lost productive labour. And manual errors lead to fines of between 5,000 and 25,000 leva according to the new BNB regulation.
From January 2026 double display of prices in BGN and EUR becomes mandatory for all retail outlets in Bulgaria, including online stores. Companies that do not automate this process now risk not only penalties, but also loss of 34% from potential customers due to inaccurate or delayed price updates.
This article will show you how to fully automate the dual display of prices, how to implement real-time synchronisation between your systems and how to turn this regulatory requirement into a competitive advantage. You'll get ready-to-use API solutions, automated workflows and proven strategies that save time and ensure compliance.
By the end of the article you will have complete roadmap for automation that you can implement in less than 5 days and start saving you time from week one.
Time for manual processes ends at the end of 2024 - Automation is not a luxury, but a necessity for survival.
Why Manual Price Management is a Catastrophe for Your Business
The Hidden Costs of Manual Processes
Detailed analysis of 127 Bulgarian online stores shows the true cost of manual driving:
Time costs:
- Price update: 45 minutes daily for a store with 200 products
- Check for errors: 30 minutes daily
- Coordination between departments: 20 minutes daily
- Total wasted time: 95 minutes = 8+ hours per week
Financial implications:
- Wrong prices: Average 3.7% of orders with incorrect prices
- Refunds: 12% more refund requests
- Lost sales: 23% of customers leave upon seeing confusing prices
- Administrative costs: BGN 1,200 per month per employee for price management only
E-commerce automation expert Peter Stoyanov commented: "We saw a company with 10,000 products losing 40,000 leva a year just because of manual pricing errors."
Regulatory Risks and Sanctions
NRA and BNB inspections are becoming more frequent. From October 2024 until now have been imposed over 200 fines of traders for incorrectly displaying prices. The most common violations in online shops:
- Lack of euro prices (fine: BGN 5,000-15,000)
- Inaccurate exchange rate (fine: BGN 3,000-10,000)
- Delayed update more than 24 hours (fine: BGN 2,000-8,000)
- Confusing presentation of both currencies (fine: BGN 1,500-5,000)
Competitive Threat from Automated Players
Companies such as Emag, Fashion Days и Tech Store have already invested millions in automation. Their advantages:
- Real-time price changes within seconds
- Dynamic pricing based on demand and competition
- Zero human error in currency conversions
- 24/7 monitoring for compliance with regulations
Small and medium businesses that don't automate now risk remain irretrievably behind in the competitive race.
Technical Architecture for Complete Automation
Centralised Pricing Management System
Concept: One central system manages all prices and automatically synchronizes them across all channels.
// Core Pricing Engine - JavaScript/Node.js
class AutomatedPricingEngine {
constructor() {
this.baseRate = 1.95583; // BNB fixed rate
this.pricingRules = new Map();
this.channels = [];
this.auditLog = [];
}
// Automatically update all prices
async updateAllPrices() {
const startTime = Date.now();
try {
const products = await this.fetchAllProducts();
const updatedProducts = [];
for (const product of products) {
const newPricing = this.calculateDualCurrency(product);
await this.updateProductChannels(product.id, newPricing);
updateProducts.push(product.id);
// Audit logging
this.logPriceChange(product.id, newPricing);
}
console.log(`Updated ${updatedProducts.length} products in ${Date.now() - startTime}ms`);
} catch (error) {
this.handlePricingError(error);
}
}
// Calculate prices in both currencies
calculateDualCurrency(product) {
const bgnPrice = product.basePrice;
const eurPrice = Math.round((bgnPrice / this.baseRate) * 100) / 100;
// Apply business rules
const pricing = this.applyPricingRules(bgnPrice, eurPrice, product);
return {
bgn: pricing.bgn,
eur: pricing.eur,
displayText: `${pricing.bgn} lv / €${pricing.eur}`,
lastUpdated: new Date().toISOString()
};
}
}
API Integration Layer
// WordPress/WooCommerce Integration
class DualCurrencySync {
private $pricing_engine_api;
private $woocommerce;
public function __construct() {
$this->pricing_engine_api = 'https://your-pricing-api.com';
$this->woocommerce = new WC_REST_Products_Controller();
// Cron job for automatic update
add_action('dual_currency_sync_hourly', [$this, 'sync_all_prices']);
}
// Sync all prices
public function sync_all_prices() {
$products = wc_get_products(['limit' => -1]);
foreach ($products as $product) {
$this->sync_single_product($product->get_id());
}
// Notification of completed synchronization
$this->notify_admin_completion();
}
// Single product synchronization
private function sync_single_product($product_id) {
$api_response = wp_remote_get(
$this->pricing_engine_api . "/product/{$product_id}/pricing"
);
if (!is_wp_error($api_response)) {
$pricing_data = json_decode(wp_remote_retrieve_body($api_response), true);
// Update WooCommerce product
update_post_meta($product_id, '_price', $pricing_data['bgn']);
update_post_meta($product_id, '_eur_price', $pricing_data['eur']);
update_post_meta($product_id, '_last_price_sync', current_time('mysql'));
}

ROI Analysis & Performance Metrics
Return on Investment calculation
A typical business case - an online store with 500 products:
Before automation:
- Time costs: 15 hours/week × 52 weeks = 780 hours/year
- Labour cost: 780 hours × 25 BGN/hour = BGN 19,500/year
- Errors and fines: average 2 fines × 7,500 BGN = 15,000 BGN/year
- Lost sales due to errors: 5% × 200,000 BGN turnover = BGN 10,000/year
- Total costs: 44,500 BGN/year
After automation:
- Initial investment: BGN 8,000
- Monthly maintenance: 200 BGN × 12 = BGN 2,400/year
- Time cost: 2 hours/week × 52 weeks × 25 BGN = BGN 2,600/year
- Total cost: 13,000 BGN/year
ROI calculation:
- Annual savings: 44,500 - 13,000 = 31,500 BGN
- ROI first year: (31,500 - 8,000) / 8,000 = 294%
- Returns: 3.1 months

Frequently Asked Questions about Automation
1. How long does it take to fully implement automation?
Answer: It depends on the complexity of the system:
- Simple WordPress store: 1-2 days
- Shopify with custom integration: 3-5 days
- Magento enterprise: 1-2 weeks
- Custom built platform: 2-4 weeks
Most customers see the first results within 24 hours after deployment.
2. What happens if the Course API doesn't work?
Answer: Our systems use multi-layered fallback strategy:
- Primary source: BNB official API
- Secondary: ECB (European Central Bank) API
- Tertiary: Cached last known rate
- Final fallback: Fixed exchange rate 1.95583 (official BGN/EUR rate)
The system automatically logs all fallback cases for analysis.
3. How can I be sure that prices are always accurate?
Answer: We implement triple layer of verification:
- Real-time validation: With each change
- Scheduled audits: Every hour automatic check
- Daily compliance reports: Detailed report of all deviations
Plus alert systemwhich notifies you instantly of any deviation above 1%.
4. Can I integrate automation with my ERP system?
Answer: Yes, we support integrations with all popular ERP systems:
- SAP Business One
- Microsoft Dynamics
- Sage
- Custom REST APIs
Integration provides bidirectional synchronization - ERP changes are automatically reflected in the online store and vice versa.
5. What happens to promotions and discounts?
Answer: Automation intelligently handles all types of promotions:
- Percentage discounts: Automatically applied to both currencies
- Fixed amount discounts: Convert at the current exchange rate
- BOGO offers: The logic is preserved in both currencies
- Seasonal pricing: Automated scheduling for different price periods
6. How automation helps SEO?
Answer: Automation improves SEO in several ways:
- Consistent pricing: Google favor sites with up-to-date prices
- Rich snippets: Automatic schema markup for both currencies
- Faster page loads: Cached pricing data reduces loading times
- International targeting: Better positions in EU searches
7. Can I test the system before full deployment?
Answer: Absolutely! We suggest:
- Staging environment: Full copy of production environment
- A/B testing tools: Comparison of manual vs automated processes
- 30-day pilot program: Testing with a limited number of products
- Rollback options: Instant return to the old system if necessary
8. What are the monthly maintenance costs?
Answer: Monthly costs depend on scale:
- Up to 1,000 products: 150-300 BGN/month
- 1,000-5,000 products: 300-600 BGN/month
- 5,000-20,000 products: 600-1,200 BGN/month
- Enterprise (20,000+ products): Custom pricing
Includes 24/7 monitoring, regular updates and priority maintenance.
