Enterprise Commerce Infrastructure.
Your store never sleeps. Multi-tenant isolation, edge-cached delivery, and background job orchestration — built for merchants who can't afford downtime.
Engineered for multi-tenant scale.
Every architectural decision optimizes for tenant isolation, low latency, and operational reliability across thousands of concurrent merchants.
Multi-Tenant Data Isolation
Every API request is scoped to a single tenant via getTenantClient(shopId). PostgreSQL row-level filtering ensures data never leaks between merchants. Each shop operates in complete isolation with dedicated connection scoping.
Edge-Cached Storefronts
Product catalogs and storefront pages are served from edge nodes closest to the customer. The Next.js App Router renders server-side at the edge, targeting sub-50ms api response times globally. Static assets are cached with month-long TTLs.

Cart recovery emails, SMS notifications, webhook fan-out, and order confirmations are processed by a dedicated BullMQ worker. Jobs are queued, retried with exponential backoff, and monitored via Sentry for real-time error tracking.

Vantemo is designed for EU regulatory compliance and enterprise-grade security from the ground up. No shortcuts, no afterthoughts.
- PCI Compliance via StripeCard data never touches Vantemo servers. All payment processing is handled directly by Stripe, maintaining PCI DSS compliance without additional merchant burden.
- httpOnly Cookie AuthenticationSession tokens are stored in httpOnly cookies with
credentials: 'include'— never exposed to client-side JavaScript, preventing XSS token theft. - GDPR-Ready with Published DPAA published Data Processing Agreement and transparent sub-processors list are available for all merchants.
- Real-Time Error MonitoringSentry is active across all four applications (storefront, API, admin, worker), providing instant alerting on exceptions, performance regressions, and unhandled errors.

Infrastructure FAQ
Architecture, security, and compliance details for technical evaluation.
What is Vantemo?
Vantemo is an e-commerce platform that lets first-time sellers open an online shop in under 15 minutes with no coding required. For technical teams: it is a multi-tenant, API-first platform built on Next.js, Node.js, and PostgreSQL. It unifies headless storefront rendering, global payment processing via Stripe, and automated cart recovery (email + SMS) into a single scalable ecosystem. The platform targets European merchants with EUR-first multi-currency support, GDPR compliance, and sub-50ms API response times.
Is Vantemo GDPR compliant?
Yes. Vantemo is designed for EU regulatory compliance from the ground up. A published Data Processing Agreement (DPA) and transparent sub-processors list are available at vantemo.com/dpa and vantemo.com/sub-processors. Tenant data is logically isolated at the database level, and httpOnly cookie authentication prevents client-side token exposure.
What technology stack does Vantemo use?
Vantemo is built as a TypeScript monorepo (pnpm + Turborepo) with four applications: a Next.js 15 App Router storefront, an Express API server, a React admin dashboard, and a BullMQ background worker. The data layer uses PostgreSQL with Prisma ORM, Redis for caching and job queues, and Stripe for payment processing. All apps share type-safe contracts via a shared Zod schema package.
How does Vantemo isolate tenant data?
Every API request is scoped to a single tenant using getTenantClient(shopId), which returns a Prisma client pre-filtered to that shop. Cross-tenant queries require getSystemClient() with explicit authorization. Raw SQL queries must include a manual WHERE shop_id clause. This three-layer isolation model ensures merchant data never leaks between tenants.
What is Vantemo's uptime and performance?
Vantemo targets 99.99% uptime with sub-50ms API response times. Storefront pages are edge-cached via Cloudflare for global low-latency delivery. The platform processes thousands of events per second natively, including webhook fan-out, cart recovery triggers, and real-time analytics ingestion. Errors are tracked in real-time via Sentry across all four applications.
How does a checkout request flow through Vantemo?
A checkout follows six stages: (1) the browser sends a cart to the Cloudflare edge, (2) the Next.js storefront forwards the request to the Express API, (3) the API validates cart contents, calculates tax, and applies discounts, (4) Stripe creates a PaymentIntent and returns a client secret, (5) the browser completes payment via Stripe Elements, (6) a Stripe webhook confirms the charge, the API creates the order, and BullMQ queues confirmation emails and webhook fan-out to external systems.
Does Vantemo support cart recovery automation?
Yes. Vantemo provides automated abandoned cart recovery via both email and SMS channels. Email recovery triggers immediately after cart abandonment. SMS recovery fires 45 minutes after abandonment (15 minutes after the first email), respecting quiet hours (10 AM to 7 PM local time). SMS uses credit-based billing with per-country multipliers and requires PRO tier or above. The system supports Twilio with per-tenant dedicated numbers and alphanumeric sender IDs for EU compliance.
