WooCommerce development with the freedom of open source and the engineering to scale

The WooCommerce plugin is free; the cost is the build and ongoing care. Across the market, a premium-theme store typically runs about $3,000-$8,000, while a fully custom store with bespoke design and complex integrations commonly costs $15,000-$80,000+ with an agency, and maintenance retainers generally fall between $500 and $3,000+ per month. Your exact number depends on design complexity, integrations, and whether data is being migrated. At 10turtle you get a fixed, itemized quote after a free audit, so you only pay for what your store needs.

Yes - that's a core part of the work. We migrate products, customers, orders, and content with integrity, and map old URLs to new ones one-to-one so search engines keep your rankings. We validate the migration on a staging copy first and keep downtime minimal at go-live. The biggest risk in any migration is unmapped redirects and lost SEO equity; preventing that is exactly what we plan for.

Yes, when it's engineered for scale. The platform powers everything from small shops to high-traffic stores, and High-Performance Order Storage (HPOS) gives it dedicated, indexed order tables built for transaction volume - WooCommerce reports up to 5x faster order creation and order lookups up to 40x faster. The performance you get at scale depends on the architecture: HPOS, proper caching, a healthy database, and hosting sized for your order volume. That's the engineering we specialize in.

HPOS (High-Performance Order Storage) stores order data in purpose-built tables instead of the old WordPress posts tables that were never designed for commerce. It's enabled by default on new stores since WooCommerce 8.2, but millions of older stores still run the legacy structure and miss the speed gains. If your store predates late 2023, you likely benefit from migrating - we do it safely using compatibility mode and full plugin-compatibility checks so nothing breaks during the switch.

Yes. The shift to block-based Cart and Checkout (which use the Store API instead of the old jQuery checkout) commonly breaks custom fields, payment/shipping logic, and tracking pixels that listened on legacy events. We diagnose the dependency that broke, migrate custom fields to the Additional Fields API, and repair tracking at the server-side action layer so your funnel data stays accurate.

Both, as equal specialisms. We build new WooCommerce stores from scratch on the modern stack, and we redesign, redevelop, and migrate existing stores - including replatforming from Shopify, Wix, or Squarespace. We are experts in redesign and redevelopment, so you don't have to start over to get a modern store.

Both, deliberately. We use well-maintained extensions where they're the right fit and develop custom WooCommerce plugins when they're not - built on official hooks and CRUD methods so they stay compatible through core updates, rather than direct database hacks that break later.

WooCommerce core itself isn't PCI-certified because it doesn't handle card data directly - final PCI DSS responsibility sits with the store owner. We reduce that scope by integrating hosted, PCI-compliant gateways (Stripe, PayPal, WooPayments), enforcing SSL, and securing your hosting. On accessibility, we build to WCAG 2.1-2.2 AA, which also supports ADA and European Accessibility Act requirements - important now that accessibility-related lawsuits are at record highs.

You own everything - fully. WooCommerce is open source, so the code, the database, and your customer data are yours with no platform lock-in and no per-sale platform fee; you can host it where you like and take it anywhere. On timing, most custom builds run a few weeks to a few months from kickoff to launch, with migrations adding time for data and redirect work. We give you a realistic timeline in the fixed-scope proposal after the free audit, and we build on staging so you see progress throughout.
