Many companies have a store on Shopify or WooCommerce. Few have a store that scales without a rewrite.

If any of this sounds familiar, you are in the right place.

✗ The store slows down at peak hours — Black Friday is a disaster, not a success

✗ Every design change needs a developer, and the costs grow exponentially

✗ Your SaaS platform (Shoper, Idosell) will not allow the custom checkout you need

✗ Integration with ERP / WMS / accounting is a constant rescue mission of macros and webhooks

✗ Competitors load faster, have better UX and higher conversion — your store has fallen behind

✗ You dread migration, because last time you moved from PrestaShop to WooCommerce and lost your SEO

Pricing

The price isn't a secret, and it isn't magic

The ranges in the calculator are based on 20+ online store projects delivered over the last 5 years. Every price accounts for:

01|ARCHITECTURE

A stack-first decision

A two-week analysis phase — mapping integrations, choosing the architecture (headless or monolith), auditing the existing store if you are migrating. Without it, a store costs twice as much once the work is under way.

02|PERFORMANCE

Scalability included in the price

Next.js + CDN, ISR (incremental static regeneration), a payment gateway matched to your scale. The store withstands a 100× traffic spike with no infrastructure changes.

03|OWNERSHIP

Code in your own repository

From day one the code is on GitHub or GitLab under your account. No vendor lock-in — you can change agency without rewriting the store from scratch.

The calculator below gives a range of ±20%. A precise quote follows the integration analysis and discovery phase.

Why

Why Digital Vantage?

Here are the concrete reasons companies chose Digital Vantage for their online store.

MIGRATION

Moving from a monolith to headless? Without losing SEO.

A staged migration plan that preserves URLs, 301 redirects, product data and order history. Your Google rankings do not drop.

B2B

A B2B store with custom logic? That's our everyday work.

Per-customer price lists, credit limits, ERP integrations (e.g. SAP), a dedicated checkout flow. We have been doing this for five years.

SCALING

Your store works, but too slowly? Scalable architecture as standard.

CDN, edge caching, lazy loading, Core Web Vitals above 90. The store loads in a second and conversion rises by 15-30%.

What does working with us look like?

  1. 01
    Free consultation

    A 30-minute call. We audit the existing store (if you are migrating) or map your needs. The plan costs nothing.

  2. 02
    Discovery

    2-3 weeks. Architecture choice (headless or monolith), payment gateway selection, ERP/WMS integration mapping. Output: an SRS and an estimate accurate to ±10%.

  3. 03
    UX / UI design

    Wireframes → Figma mockups → a checkout-flow prototype for testing. Iterations before a line of code is written.

  4. 04
    Store MVP

    8-12 weeks. The first version with the core features: catalog, cart, checkout, admin panel. Deployed to staging and tested with real products.

  5. 05
    Data migration and integrations

    4-6 weeks. Importing products, customers and orders. Integrations with ERP, WMS, couriers and payments. End-to-end testing before launch.

  6. 06
    Launch and maintenance

    A soft launch on limited traffic, monitoring, optimization. Full launch plus 30 days of stabilization included.

FAQ

Frequently asked questions

It depends on the architecture and the integrations — which is why we built an online pricing calculator. In three minutes you get an indicative range matched to your needs. In practice: a simple headless store on a Shopify backend from EUR 19,500-32,500 net, a B2B store with ERP integrations EUR 52,000-97,500, an enterprise build with a custom backend from EUR 130,000 upwards. Run the calculator, then bring specific questions to the consultation.

Headless means the frontend (what the customer sees) is separated from the backend (managing products and orders). The benefits: faster loading (Core Web Vitals above 90), a custom checkout with no platform limits, the ability to change the backend without rewriting the store, and a better position in Google. Headless makes sense when you plan to scale, have custom integrations, or your current SaaS platform is holding you back. For a first store with 50 products it is often overkill — in that case we will honestly point you to a classic solution.

Yes, and it is one of our more common scenarios. The migration plan covers: preserving the URL structure (or one-to-one 301 redirects), importing products, images, descriptions and categories, transferring order and customer history, and validating indexing in Search Console before launch. Google rankings do not drop — they often rise thanks to better Core Web Vitals.

We integrate with ERP systems (e.g. SAP), WMS, couriers (DPD, DHL and local carriers), payments (Stripe and local payment methods) and accounting software. Discovery verifies the feasibility of each integration — if something is not on the list, we check whether an API exists.

Thirty days of stabilization are included in the project price. After that we offer three levels of support:

  • Monitoring (from EUR 975/month) — uptime monitoring, alerts, a monthly performance and SEO report. No code changes.
  • Standard (from EUR 3,250/month) — the above plus hotfixes on the next business day, monthly stack updates and a 5-hour development budget.
  • Premium (from EUR 7,800/month) — the above plus five engineer-days a month, customizations, product extensions and hotfixes within four working hours.

You can also maintain the store yourself — the code and documentation are yours from day one.

Let's talk about your store

Free and without obligation.

The consultation takes 60 minutes. Whether or not you decide to work with us, you leave with an integration map and an indicative estimate.
