Platform
E-Commerce That Fits Your Business
Not a one-size-fits-all storefront. mercstack adapts to how you actually sell — across countries, languages, and customer types.
B2C First, B2B Ready
Retail-first commerce with trade features when you need them: quotations, net pricing, credit limits, and purchase orders — there when your business customers need them, invisible when they don't.
Industrial-Grade, Not Generic
Built for real products with real stock — not another drop-ship t-shirt store. ERP-native inventory, real-time stock sync, and proper invoicing come standard. If your business runs on a warehouse, not a spreadsheet, mercstack fits.

Go Cross-Border Without the Complexity
Markets & Languages, Handled
Add any market, and mercstack handles the rest: per-country VAT rates at any percentage, shipping zones, pricing rules, and localized URLs. Your catalog stays in sync — one product, any number of markets, zero duplication. The four shown above are just the starting point.
Each market speaks your customers' language. mercstack ships with English, German, and Slovenian out of the box — with market-specific URL structures (<code>/de-de/</code>, <code>/si-sl/</code>, <code>/it-en/</code>) so SEO and caching just work.
Capabilities
Everything You Need to Run a Modern Store
From payments to shipping to ERP invoicing — the full stack, integrated.
Multi-Language Storefronts
English, German, Slovenian, and more — with market-specific URL structures for correct SEO and caching per locale.
Real-Time Stock & Inventory
Stock levels synced live from your ERP. Customers see actual availability — not what was accurate yesterday. No oversells.
Integrated Payments
Stripe, PayPal, bank transfer, cash on delivery — online and offline. One unified checkout, no redirects, no dropped carts.
Smart Shipping
Per-zone rates, free-shipping thresholds, and express options. Rules adapt automatically to country and cart value.
ERP-Native Invoicing
Invoices, delivery notes, and credit notes live in your ERP — not locked in a siloed e-commerce database you can't access.
White-Label Ready
Your domain, your branding, your theme. mercstack runs under the hood — your customers see your brand, not ours.
AI-Powered Content
Translate product descriptions, generate copy, and analyze sentiment — powered by Anthropic. Reach new markets without the manual effort.
Customer-Specific Pricing
Per-customer discounts, last-price cache, and volume pricing rules. Trade customers see their prices automatically — no manual quoting for repeat buyers.
Margin Protection Calculator
Configurable minimum-margin floor across your catalog. Price-cascade resolver prevents selling below cost — even with stacked customer discounts and volume breaks.
