Ecommerce Migration and Replatforming Services

The cost is driven by four things far more than by the number of products. The first is catalog complexity: configurable products, option sets, bundles and customer-specific pricing take much longer to map than a flat list of simple products. The second is the number of live integrations, because each ERP, PIM, warehouse or tax connection has to be rebuilt and tested against real orders. The third is custom behavior on the old store, such as checkout rules or B2B quoting, that the new platform does not do out of the box. The fourth is the storefront approach, since a customized theme costs much less than a headless build. We do not publish a single price, because any number given before seeing your integrations would be a guess. The migration plan exists to replace that guess with an estimate range for each phase.

A short dip of a week or two while Google recrawls and reprocesses the new URLs is normal. A lasting loss is not, and it almost always comes from something preventable. The usual causes are old URLs left without redirects, redirects that chain through two or three hops, category and product templates that dropped their structured data or their descriptive copy, and key content that the new theme only renders with JavaScript. We prevent those by building the redirect map from a full crawl of the live site plus its backlink targets, because sitemaps rarely list everything that has links pointing at it. We then compare titles, canonicals, headings and structured data template by template on staging before launch, and keep staging behind authentication so it cannot be indexed early. After launch we watch Search Console daily for the first few weeks.

Start from what the business needs the platform to do, not from which platform is fashionable. Shopify suits brands that want low maintenance, a large app ecosystem and a checkout they do not have to run themselves, and Shopify Plus extends that to higher volume and several storefronts. BigCommerce suits mid-market and B2B catalogs that need more native catalog flexibility and fewer apps. Magento and Adobe Commerce suit businesses with complex B2B pricing, multiple store views or deep ERP integration, where the control is worth the maintenance. Salesforce Commerce Cloud suits large retailers already invested in Salesforce. We build on all four, so we have no commission riding on the answer. The migration plan scores your requirements against each candidate and states the trade-offs in writing, so the decision can be reviewed rather than taken on trust.

Mostly, yes. Products, categories, customers, addresses and past orders can all be migrated, although historical orders usually arrive as records for reference and reporting rather than as live orders that can be refunded through the new platform. Customer passwords are the main exception. Every serious platform stores them as one-way hashes, so they cannot be moved, and customers are invited to activate their accounts on the new store instead. Timing those invitations well matters more than most teams expect. Saved payment cards and subscriptions are a separate question that depends on your payment processor: card tokens can often be transferred between processors on request, but it takes planning and lead time. Loyalty points, store credit and gift card balances need their own mapping. The migration plan lists which of your data moves, which transforms, and which needs a customer-facing message.

For a mid-market store with a standard set of integrations, three to six months from kickoff to launch is a realistic range, with the migration plan itself taking two to three weeks at the start. Enterprise and B2B projects with contract pricing, multiple storefronts or heavy customization run longer, and six to twelve months is common. The timeline is set less by the size of the catalog than by three other factors: how many integrations need rebuilding, how clean the source data is, and whether the business can hold back new features during the cutover window. Most delays come from discovering an integration or a data problem halfway through the build. That is why we map the data and inventory every integration before quoting, so the schedule reflects what is really in your store rather than what came up on a discovery call.
