How to Migrate from BigCommerce to WordPress (+ WooCommerce)

BigCommerce is a capable hosted platform, but its rigid theme system, per-plan API call limits, and forced pricing tiers push many merchants toward something they can fully own. Moving to WordPress with WooCommerce trades a closed SaaS environment for an open, self-hosted stack where you control the code, the checkout, the hosting bill, and every line of the design. That freedom is real, but so is the work: a store migration touches products, customers, orders, URLs, payment gateways, and years of accumulated SEO equity.

This guide walks through the entire move from BigCommerce to WooCommerce the way an agency actually runs one, not as a one-click fantasy. You'll see what genuinely transfers, what silently breaks, and where the migration usually goes wrong, plus a concrete step-by-step process for exporting your catalog, rebuilding on WordPress, mapping redirects, and launching without tanking your rankings.

If you'd rather hand the whole thing off, our website migration services cover the technical lift end to end. But whether you DIY or delegate, understanding the moving parts below will save you from the expensive mistakes.

Why Merchants Leave BigCommerce for WooCommerce

The reasons are rarely emotional. They come down to control, cost, and flexibility as a store scales:

• Total design freedom. BigCommerce themes are constrained by Stencil and a limited component library. WordPress plus a builder like Gutenberg blocks, Elementor, or a custom theme lets you design any layout, landing page, or content-commerce hybrid you want.
• Content and SEO depth. WordPress is the strongest content management system on the web. WooCommerce stores get first-class blogging, category content, and schema control that BigCommerce's thinner blog and metadata tools can't match.
• Predictable, lower cost at scale. BigCommerce enforces annual sales thresholds that auto-bump you to a pricier plan. WooCommerce is free software; you pay only for hosting, a few plugins, and development.
• No API call ceilings or platform lock-in. You own the database and files, so you can move hosts, customize checkout, and integrate any tool without SaaS limits.
• A massive plugin and developer ecosystem. Tens of thousands of extensions and a huge talent pool mean almost any requirement has a supported solution.

What Transfers Cleanly and What Breaks

Setting expectations here prevents launch-day panic. Some assets migrate with structured exports; others must be rebuilt from scratch.

Transfers with effort (structured data):

• Products, including SKUs, prices, descriptions, weights, and inventory levels.
• Product images and downloadable files (re-uploaded and re-linked).
• Categories, though BigCommerce's category tree may need remapping to WooCommerce's structure.
• Customers and, in most cases, historical orders via a migration tool or CSV.

Breaks or must be rebuilt:

• Theme and design. Nothing visual carries over. Your Stencil theme has no WordPress equivalent, so the storefront is rebuilt in a WooCommerce theme.
• BigCommerce apps. Every installed app (reviews, subscriptions, upsells, loyalty) must be replaced with a WordPress plugin equivalent and reconfigured.
• Payment and shipping config. Gateways like Stripe, PayPal, or Authorize.Net are reconnected inside WooCommerce; you can't export live payment credentials.
• URL structure. BigCommerce and WooCommerce use different default URL patterns for products and categories, which is exactly why redirects are non-negotiable (more below).
• Customer passwords. These are hashed and rarely transfer; customers typically reset on first login.
• Redirects and metadata quirks. Any 301s you built inside BigCommerce need to be recreated in WordPress.

Step 1: Export Your BigCommerce Data

Start in your BigCommerce control panel. Under Products > Export, pull your full catalog to CSV using the default Bulk Edit template, which includes SKUs, pricing, custom fields, and image URLs. Export customers from Customers > Export, and if your plan allows, export order history as well. Separately, download or bulk-fetch your product images, because CSV rows reference image URLs on BigCommerce's CDN that will eventually go dark.

Also export your existing URL list. Crawl the live BigCommerce store with a tool like Screaming Frog and save every indexed product, category, blog, and page URL to a spreadsheet. This crawl becomes the master source for your redirect map. Finally, record your current top pages from Google Search Console and Google Analytics so you have a rankings and traffic baseline to compare against after launch.

Step 2: Stand Up WordPress and WooCommerce

Provision quality managed WordPress hosting (Kinsta, WP Engine, Cloudways, or SiteGround are common choices) and install WordPress, ideally on a staging subdomain so you can build privately. Install and activate the WooCommerce plugin, then run its setup wizard to set your store address, currency, tax, and shipping basics.

Next, build the storefront. Choose a WooCommerce-ready theme or commission a custom one, then recreate your BigCommerce look, navigation, and brand feel. This is the phase where design freedom pays off, and where a professional WordPress development team earns its fee by matching or improving on your old storefront rather than settling for a generic template. Install the plugins that replace your former BigCommerce apps now, so you can configure them alongside the catalog import.

Step 3: Import Products, Customers, and Orders

You have two realistic paths. For smaller catalogs, use WooCommerce's built-in CSV importer (Products > Import), mapping each BigCommerce column to the matching WooCommerce field. For larger or more complex stores, a dedicated tool such as Cart2Cart, LitExtension, or a WP All Import setup handles products, variants, customers, and orders in one automated pass with less manual cleanup.

Whichever route you choose, plan for hands-on QA:

• Verify that product variants, attributes, and options mapped correctly, since BigCommerce and WooCommerce model variations differently.
• Confirm images uploaded to the WordPress media library and attached to the right products, not just referenced as dead external URLs.
• Spot-check pricing, tax classes, inventory counts, and category assignments.
• Recreate custom fields, product reviews, and any specification tables that don't map automatically.

For stores with unusual data models, ERP hooks, or B2B pricing logic, custom import scripting and custom development and CRM integration often beats forcing everything through a generic connector.

Step 4: Build the 301 Redirect Map (Protect Your SEO)

This is the single most important step for preserving rankings, and the one most DIY migrations botch. Because WooCommerce URLs differ from BigCommerce's, every old URL must 301 redirect to its new equivalent so search engines and inbound links pass their authority forward instead of hitting 404s.

Take the crawl from Step 1 and build a two-column map: old BigCommerce URL to new WordPress URL. Match products, categories, blog posts, and static pages one to one. Where a page has no direct equivalent, redirect it to the closest relevant category or parent, never to the homepage in bulk. Implement the redirects in WordPress with a plugin like Redirection or at the server level in your .htaccess or Nginx config for speed at scale. Our guide to building a 301 redirect map walks through the format and edge cases in detail.

Before launch, work through a full website migration SEO checklist: preserve title tags and meta descriptions, keep your heading structure, retain image alt text, add product schema, generate a fresh XML sitemap, and confirm your robots.txt won't block the new store once it goes live.

Step 5: Test, Launch, and Monitor

On staging, run real transactions in your payment gateway's test mode, checking tax, shipping rates, coupons, order confirmation emails, and inventory decrementing. Click through mobile and desktop layouts, test search and filtering, and validate a sample of redirects.

When you're confident, launch by pointing your domain's DNS to the new host (lower the DNS TTL a day ahead to speed propagation). Immediately after cutover:

• Switch payment gateways from test to live mode and place one real order.
• Submit the new XML sitemap in Google Search Console and request indexing of key pages.
• Crawl the live site to confirm redirects fire and no critical 404s remain.
• Watch Search Console coverage, rankings, and analytics daily for the first few weeks; a small, temporary dip is normal, a sustained drop signals a redirect or indexing problem to fix fast.

A structured, professional web development process keeps these steps sequenced correctly so nothing ships broken.

Timeline and Cost: What to Realistically Expect

A straightforward store with a few hundred products, a standard theme, and clean data can move in two to four weeks. A larger catalog with thousands of SKUs, custom apps to replace, B2B pricing, and a bespoke design typically runs six to twelve weeks once design, QA, and redirect mapping are done properly.

On cost, a capable DIY migration mostly costs your time plus hosting and a few premium plugins (often a few hundred dollars a year). A professionally managed migration is usually billed hourly. At eSEOspace's $80/hour rate, a typical small-to-midsize store migration lands in the low-to-mid four figures depending on catalog size, design complexity, and how many BigCommerce apps need custom replacements. The redirect and SEO work is where cutting corners costs the most later, so it's worth budgeting for regardless of which path you take.
