Disclosure: WEBDIGITA appears at position 3. Our eCommerce migration services cover BigCommerce to WooCommerce data migration, plugin replacement audit, redirect mapping and post-launch maintenance.
The short answer:
The reasons to move from BigCommerce to WooCommerce rather than Shopify are specific. WordPress’s CMS capability is the most common driver: brands who want a large content library, editorial section or comparison hub alongside eCommerce that Shopify’s basic blog cannot support. Zero platform and transaction fees on WooCommerce is the second driver: at significant GMV with a non-Shopify Payments gateway, Shopify’s 0.5% transaction fee (Advanced) adds up where WooCommerce charges nothing. B2B pricing flexibility without paying for Shopify Plus is the third: WooCommerce B2B plugins (WholesaleX, B2BWoo) handle complex trade pricing at lower cost than Shopify Plus. The honest counter-argument: moving from BigCommerce to WooCommerce means accepting server management, WordPress and WooCommerce update responsibility, plugin compatibility management and security patching that BigCommerce handled for you. If that operational overhead is not already your team’s strength, Shopify may be a better destination than WooCommerce regardless of cost comparison.
- BigCommerce is a fully managed SaaS platform – hosting, security patches, platform updates and PCI compliance are handled by BigCommerce. WooCommerce is self-hosted: every one of those responsibilities transfers to the merchant or their agency
- WooCommerce charges no platform fees and no transaction fees regardless of payment gateway. BigCommerce charges no transaction fees but has monthly platform fees (£27-£269/month plus enterprise). The TCO comparison at scale depends heavily on WooCommerce hosting costs and maintenance overhead
- UK agency costs for a BigCommerce to WooCommerce migration range from £6,000 for a simple catalogue to £25,000+ for stores with complex B2B pricing, large catalogues and ERP integration
Why WooCommerce rather than Shopify? The honest comparison
Most BigCommerce merchants evaluating replatforming end up at Shopify. The app ecosystem, managed hosting and lower technical overhead make Shopify the more obvious destination. WooCommerce is the right choice for a specific subset. Here is the decision framework I use.
| Choose WooCommerce if… | Choose Shopify if… |
|---|---|
| Content marketing is a primary growth channel – you need a WordPress editorial environment alongside eCommerce, not a bolt-on blog | You want managed SaaS with no server responsibility and are willing to pay platform fees for that convenience |
| You use a non-Shopify Payments gateway at significant GMV where Shopify’s 0.5% transaction fee is a material cost | Your payment gateway is Shopify Payments or your GMV makes the transaction fee negligible |
| Your B2B pricing requirements are complex but your GMV does not justify Shopify Plus subscription cost (£1,800/month) | You need Checkout Extensibility, expansion stores or Shopify’s native Plus B2B module and can justify the Plus cost |
| Your team has or will have in-house WordPress developer capability to manage updates, plugins and hosting | Your team has no appetite for self-hosted platform management and wants someone else responsible for uptime |
| Complete data ownership and no vendor dependency matter commercially – you want to own the code base | You want a vendor-backed platform with dedicated support and no infrastructure decisions to make |
What BigCommerce merchants inherit when moving to WooCommerce
BigCommerce handles hosting, security patches, PCI compliance, CDN configuration and platform updates. WooCommerce on WordPress does not. Before briefing any WooCommerce migration agency, I would confirm that the following responsibilities are assigned to either internal team or agency retainer post-launch:
- WordPress core updates – major, minor and security releases. Skipping WordPress updates introduces security vulnerabilities; applying them without staging testing introduces site breakage risk
- WooCommerce updates – major releases (5.x, 6.x, 7.x, 8.x, 9.x) frequently introduce breaking changes for custom code and incompatible plugins. Every update needs testing on a staging environment before production
- Plugin compatibility management – WooCommerce plugins do not always update in sync with WooCommerce core. Plugin conflicts after a WooCommerce update are the most common post-launch emergency for WooCommerce stores. Someone needs to own this
- PHP version upgrades – WordPress and WooCommerce regularly move their minimum PHP requirements. Staying on outdated PHP introduces security risk; upgrading PHP can break plugins
- Hosting and server monitoring – WooCommerce performance at scale requires Redis caching, correct PHP worker configuration and database query monitoring. BigCommerce handled all of this natively
- Security patching and malware scanning – WordPress and WooCommerce have a larger attack surface than BigCommerce. Active security monitoring is required, not optional
WooCommerce agencies that include a post-migration maintenance retainer as a named product address this directly. Agencies that deliver the WooCommerce build and move on do not.
BigCommerce to WooCommerce: data migration specifics
| Data type | Migration notes |
|---|---|
| Products and variants | BigCommerce product export via CSV or API. WooCommerce import via WooCommerce CSV importer or Matrixify. Product options map to WooCommerce attributes; variants map to WooCommerce variations. SKUs, prices and stock levels transfer cleanly |
| Categories | BigCommerce categories become WooCommerce product categories. Hierarchical structure transfers. Navigation menu needs rebuilding in WordPress |
| Customers | BigCommerce customer export via CSV. WooCommerce import via CSV or user import plugin. Passwords cannot be migrated (different encryption). All customers need to reset passwords post-launch |
| Orders | Historical orders import via Matrixify or custom script. Order status mapping between BigCommerce and WooCommerce status labels requires manual mapping |
| URLs | BigCommerce and WooCommerce can both use clean URL structures, but they differ. Every product and category URL needs auditing and 301 redirects configured before launch |
| Blog content | BigCommerce has a basic blog. WordPress offers a significantly richer content environment. Blog content migrates via CSV or RSS import; internal link references to BigCommerce URLs need updating to WordPress paths |
| Gift certificates and discount codes | BigCommerce gift certificates and discount codes need manual recreation in WooCommerce. Automated migration tools handle basic discount code transfer with limitations |

How we selected and ranked these agencies
I evaluated seven agencies against three criteria: confirmed WooCommerce migration and development capability, evidence that their post-migration model covers the maintenance responsibilities that BigCommerce was handling, and UK presence confirmed from public sources. Kanuka Digital leads because their Platinum Certified WooExpert status, ISO27001 certification and B2B catalogue migration track record (Bacofoil, Tile Giant) provides the strongest combination of WooCommerce technical depth and information security accreditation on this list. WEBDIGITA appears at position 3 per this guide’s positioning.
Agency profiles
1. Kanuka Digital
Platinum Certified WooExpert and ISO27001 certified – the highest WooCommerce certification paired with information security accreditation, directly relevant for BigCommerce merchants in regulated or compliance-sensitive sectors moving to a self-hosted WooCommerce environment

- ISO27001 information security certification covers the WooCommerce server environment, data handling and access controls. BigCommerce handled PCI compliance and security natively. Moving to self-hosted WooCommerce means accepting that responsibility; Kanuka’s ISO27001 certification demonstrates they manage it to an audited standard
- Bacofoil and Tile Giant as named B2B clients confirm WooCommerce catalogue migration at the trade distribution scale where BigCommerce merchants with B2B requirements typically operate
Evidence sources: kanukadigital.com (Platinum WooExpert, ISO27001 and ISO9001 confirmed, Bacofoil/Tile Giant/Mountfield clients, B2B migration capability)
Ideal for
BigCommerce merchants in healthcare, pharmaceutical, veterinary or regulated sectors where moving to self-hosted WooCommerce requires ISO27001 information security certification from the agency managing the environment.
Think twice if
You need a London city office. Kanuka is Stafford-based and primarily remote. Strong WooCommerce depth, different in-person model from a city-centre agency.
2. Envisage Digital
WooCommerce Partner and Adobe Bronze Solution Partner with a 2025 eCommerce Awards Bronze win for B2B WooCommerce – and 24/7 support options for BigCommerce merchants who are accustomed to SaaS platform uptime guarantees and need comparable coverage post-migration

- eCommerce Awards Bronze 2025 for Commercial Washrooms (Best B2B Website of the Year) on WooCommerce demonstrates independently judged B2B WooCommerce delivery at the trade scale that many BigCommerce merchants represent
- Both WooCommerce and Adobe Commerce experience means Envisage can evaluate the platform decision honestly from direct operational experience of both – relevant for BigCommerce merchants who are also considering Magento as a migration destination
Evidence sources: envisagedigital.co.uk (WooCommerce Partner, 24/7 support, Commercial Washrooms eCommerce Awards 2025 Bronze confirmed), LinkedIn (Bournemouth, London specialists)
Ideal for
BigCommerce B2B merchants moving to WooCommerce who need 24/7 post-migration support comparable to their BigCommerce SaaS uptime coverage – particularly those evaluating both WooCommerce and Magento as destination platforms.
Think twice if
You need Platinum WooExpert certification for procurement. Envisage holds WooCommerce Partner status – Platinum requirements point toward Kanuka Digital.
3. WEBDIGITA
BigCommerce to WooCommerce migration where the plugin replacement audit, hosting configuration, B2B pricing mapping and post-launch maintenance retainer are scoped as a single engagement – not four separate briefings
- Specialisms
- BigCommerce to WooCommerce migration, plugin replacement audit, WooCommerce hosting configuration (Redis, PHP workers), B2B pricing migration (WholesaleX, B2BWoo), 301 redirect mapping, post-launch maintenance retainer, ERP integration
- Office Locations
- London, Reading, Birmingham
- Team Size
- 11-50
- Notable Clients
- Long-term B2B and DTC eCommerce partnerships averaging 8-10 years, founded 2016
- WooCommerce Status
- WooCommerce Partner
Why choose WEBDIGITA
- Plugin replacement audit before migration scope is agreed: every BigCommerce built-in feature and app is mapped against its WooCommerce plugin equivalent, with performance impact and configuration cost per plugin estimated before development begins. The plugin audit prevents the post-migration discovery of functional gaps that drive the most common BigCommerce-to-WooCommerce budget overruns
- Hosting configuration as part of the migration scope – Redis object caching, PHP worker sizing for WooCommerce session load, staging environment matching production and performance baselines agreed as acceptance criteria. BigCommerce handled all of this natively; the WooCommerce hosting brief needs to specify it explicitly
- Post-launch maintenance retainer from the same team that built the store, covering WordPress core updates, WooCommerce releases and plugin compatibility testing – the operational overhead that BigCommerce removed from the merchant’s responsibility and that the migration is about to return
Evidence sources: webdigita.co.uk (ecommerce-migration-services, woocommerce-development, b2b-ecommerce-solutions service pages), LinkedIn (11-50, founded 2016, London/Reading/Birmingham)
Ideal for
UK BigCommerce merchants moving to WooCommerce for content ownership and B2B pricing flexibility, who want plugin audit, hosting configuration, B2B pricing migration and post-launch maintenance retainer from one agency – at competitive pricing below the UK market average of £13,000.
Think twice if
You need 100+ developers running simultaneous parallel workstreams, or Platinum WooExpert certification for a regulated sector procurement scorecard.

BigCommerce merchants near London or Surrey who want migration and a full-stack WooCommerce maintenance retainer from one agency with in-person access available throughout.

Evidence sources: harrisoncarloss.com (Certified Woo Partner, green hosting, full-service marketing confirmed, Cottage Delight client)
Ideal for
BigCommerce lifestyle and gifting merchants with sustainability commitments who want WooCommerce migration, green hosting and full-service post-migration marketing from one Certified Woo Partner.
Think twice if
Your BigCommerce migration is technically complex – enterprise B2B pricing architecture, large catalogues or ERP integration. Harrison Carloss is a full-service marketing and web agency; technically complex WooCommerce migration engineering benefits from a more development-focused specialist.
6. Fitpixels
13 years of WooCommerce-only delivery with stores currently processing up to £400,000 per month – for BigCommerce DTC merchants who want confirmation from an agency actively managing high-volume WooCommerce stores that the platform handles their order volume
- Specialisms
- WooCommerce migration and development, performance engineering, managed WooCommerce hosting, DTC health and wellness, direct developer access, Foundation/Growth/Full-Service plans
- Office Locations
- UK
- Team Size
- 11-50
- WooCommerce Status
- WooCommerce specialist (13 years)
Why choose Fitpixels
- Actively managing WooCommerce stores at £400k/month trading volume validates WooCommerce’s production capacity for BigCommerce DTC merchants concerned about whether WooCommerce handles their order volumes without the infrastructure that BigCommerce provided natively
- Managed WooCommerce hosting as part of their service model covers the hosting configuration responsibility that BigCommerce removed from the merchant – Redis, PHP workers, CDN and monitoring are managed by Fitpixels rather than left to the merchant to configure
- Direct developer access means BigCommerce merchants do not manage the migration or post-migration support through an account manager relay
Evidence sources: fitpixels.uk (13 years WooCommerce confirmed, £400k/month stores confirmed, managed hosting confirmed, direct developer access)
Ideal for
BigCommerce DTC merchants in health, wellness and supplement sectors whose WooCommerce destination includes managed hosting from a specialist actively managing high-volume WooCommerce stores.
Think twice if
Your BigCommerce store is B2B industrial with complex trade pricing. Fitpixels’ confirmed sector is DTC health and wellness – B2B WooCommerce depth sits better with Kanuka Digital, WEBDIGITA or Brown and Brown.
7. Brown and Brown
The WooCommerce specialist whose B2B pricing and checkout depth directly covers the BigCommerce B2B merchants migrating to WooCommerce for trade pricing flexibility without Shopify Plus cost
- Specialisms
- Custom WooCommerce checkout, B2B trade pricing, payment gateway integration (Stripe, Klarna, Opayo, Worldpay), ERP integration, long-term partner model
- Office Locations
- UK
- Team Size
- 11-50
- WooCommerce Status
- WooCommerce specialist
Why choose Brown and Brown
- B2B and trade pricing in WooCommerce is the primary reason many BigCommerce merchants choose WooCommerce over Shopify. Brown and Brown’s documented trade pricing capability (customer group pricing, minimum order quantities, credit terms at checkout) means the B2B requirements that BigCommerce B2B Edition handled natively are implemented correctly in WooCommerce post-migration
- Payment gateway expertise covering Stripe, Klarna, Opayo, Worldpay, Apple Pay and Google Pay – BigCommerce merchants often have complex gateway configurations that need replicating in WooCommerce at the correct hook level, not just the plugin installation
- Long-term partner model with multi-year client relationships – WooCommerce requires ongoing PHP updates, plugin compatibility management and security patching that benefit from a long-term agency relationship rather than a project-based one
Evidence sources: brownandbrown.co.uk (B2B and trade pricing confirmed, payment gateway expertise confirmed, long-term partner model confirmed)
Ideal for
BigCommerce B2B merchants moving to WooCommerce specifically for trade pricing flexibility, whose migration priority is replicating and improving B2B checkout logic and payment gateway configuration.
Think twice if
You need Platinum WooExpert certification or ISO accreditation for procurement. Brown and Brown’s credentials are evidenced through delivery track record rather than formal certification.
BigCommerce to WooCommerce migration checklist
- Map every BigCommerce built-in feature to a WooCommerce plugin. BigCommerce includes abandoned cart recovery, multi-currency, built-in reviews, gift certificates and product filtering natively. Every one of these requires a WooCommerce plugin equivalent. Audit and cost each replacement before migration scope is agreed
- Decide on hosting before briefing any agency. WooCommerce performance at your order volume requires specific hosting configuration. Confirm the hosting provider, Redis setup, PHP worker sizing and CDN configuration as part of the migration brief – not as a post-launch discovery
- Plan the customer password reset. BigCommerce and WooCommerce encrypt passwords differently. All customers need to reset their password post-migration. Build the reset email sequence and pre-migration communication into the launch plan
- Audit URLs from Google Search Console before migration. Export every BigCommerce URL receiving organic traffic. Map each to its WooCommerce equivalent and build a 301 redirect for each one before launch
- Define the post-migration maintenance model before launch. WooCommerce maintenance is the operational overhead that BigCommerce removed. Confirm before the migration is complete which agency or team owns WordPress core updates, WooCommerce updates, plugin compatibility testing, PHP version upgrades and security monitoring
For WooCommerce development and ongoing maintenance after the migration, our WooCommerce development guide covers the agencies managing live WooCommerce stores.
Final thoughts
BigCommerce to WooCommerce is an unusual migration direction for a reason. Most BigCommerce merchants moving platform go to Shopify, where managed hosting and lower operational complexity replicate what BigCommerce provided. WooCommerce is the right destination for a specific set of businesses: content-heavy brands, B2B merchants who want pricing flexibility without Shopify Plus cost, and teams who want complete platform ownership. If none of those apply, Shopify is the more defensible choice.

For plugin audit, hosting configuration and maintenance retainer at competitive pricing: WEBDIGITA. For full-stack London retainer covering hosting and SEO: Ronins. For green hosting and full-service marketing: Harrison Carloss. For DTC health and wellness with managed WooCommerce hosting: Fitpixels. For B2B trade pricing and checkout depth: Brown and Brown.
Frequently asked questions
1. Why would a business move from BigCommerce to WooCommerce instead of Shopify?
Three specific reasons justify choosing WooCommerce over Shopify as the BigCommerce migration destination. First, content marketing: WordPress's editorial environment is substantially stronger than Shopify's blog for brands building a large content library, comparison hub or resource centre alongside eCommerce. Shopify's blog covers basic publishing; WordPress covers a full CMS. Second, transaction fees: WooCommerce is self-hosted and charges no transaction fees regardless of payment gateway. Shopify charges 0.5% on Advanced and 0.2% on Plus for non-Shopify Payments transactions. At significant GMV with a non-Shopify Payments gateway, this is a material annual cost that WooCommerce eliminates. Third, B2B pricing flexibility without platform tier cost: WooCommerce B2B plugins (WholesaleX, B2BWoo) handle complex trade pricing, customer group pricing and quantity discounts at lower total cost than Shopify Plus subscription. For BigCommerce merchants whose migration is primarily driven by content, transaction cost or B2B pricing flexibility, WooCommerce is the commercially correct destination.
2. What operational responsibilities does a BigCommerce to WooCommerce migration transfer to the merchant?
BigCommerce is a fully managed SaaS platform - hosting, PCI compliance, security patches, CDN configuration and platform updates are BigCommerce's responsibility. WooCommerce is self-hosted: every one of these transfers to the merchant or their agency post-migration. The specific responsibilities are: WordPress core updates (security releases cannot be skipped without vulnerability risk); WooCommerce major release updates (each requires staging environment testing for plugin compatibility); PHP version upgrades as WordPress minimum requirements change; plugin compatibility management after any update; server and hosting configuration including Redis caching and PHP workers for WooCommerce performance at volume; and active security monitoring and malware scanning. BigCommerce merchants evaluating WooCommerce should confirm before committing to the migration that these responsibilities are assigned to either internal team or a named agency retainer. An agency that delivers the WooCommerce build without a post-launch maintenance model leaves the merchant with operational exposure they did not have on BigCommerce.
3. How much does a BigCommerce to WooCommerce migration cost in the UK?
UK agency costs range from approximately £6,000 for a simple BigCommerce store with a small catalogue and standard plugin replacements, to £25,000 or more for stores with complex B2B pricing requirements, ERP integration and large catalogues. The UK market average for a comparable mid-complexity BigCommerce to WooCommerce migration is approximately £13,000. WEBDIGITA's BigCommerce to WooCommerce migration projects are priced competitively below this market average. The migration cost should be evaluated alongside first-year WooCommerce hosting and maintenance retainer costs, which BigCommerce absorbed in its platform fee and which need explicit budgeting for a self-hosted WooCommerce environment.
