How much does an online store migration cost and how long does it take

"How much does a migration cost?" is the first question and, rightly, has no single answer. A store with 500 products and zero integrations is a different project from one with 100,000 products, an ERP and three marketplaces. Here are the real factors that move budget and timeline — so you know what to ask and what to compare.

Why there is no fixed price

A migration isn't "moving a website", it's rebuilding a business system with its data. Price depends on complexity, not page count. Anyone quoting a fixed price without seeing your catalog, integrations and source platform is guessing.

The factors that drive the budget

• Catalog size and complexity — number of products, variations, attributes, categories, configurable/bundle products.
• Source platform — how cleanly data can be exported (Shopify via API differs from an old OpenCart with custom modules).
• Historical data migration — just products, or also customers, orders, invoices, accounts.
• Integrations — couriers, invoicing, ERP, marketplace feeds (eMAG), payments.
• Design — reuse the visual identity or build a new frontend.
• Business rules — B2B pricing, price lists, group discounts, per-category VAT.
• SEO and redirects — the volume of URLs to map and protect.

How to estimate the timeline

Duration follows the same factors. Roughly, the phases are:

• Audit & plan — 5 working days: inventory, architecture, URL mapping, estimate.
• Development — the bulk: Sylius/Symfony backend + Next.js frontend, incremental staging deliveries.
• Data migration — in parallel: export, mapping, import, integrity checks.
• Integrations & testing — couriers, invoicing, payments, feeds, then QA.
• Launch — controlled cutover + monitoring.

A mid-sized store usually lands between a few weeks and a few months, depending on how many of the above are "heavy".

The cost of NOT migrating

Weigh the hidden cost of the current platform too: sales lost to poor mobile speed, SaaS fees and subscriptions, hours lost in a slow admin, plus security risk. Over 12 months these often exceed the cost of migrating.

How to get an accurate estimate

A firm price can't be given over the phone. That's why we start with the migration audit: 5 working days, from 1,500 lei + VAT, deducted in full from the migration price if you go ahead with us. To start it, prepare: your current platform, the approximate number of products, the required integrations, whether you want orders/customers migrated, and whether you keep or change the design.

Request the migration audit — or, if you'd like an opinion first, we take a free look at three pages of your store and tell you within 2 working days whether it makes sense.
