Everything Shopify,
done properly.
01
Custom Shopify Theme Development
Hand-coded Liquid themes built to your brand, no generic templates, no page-builder bloat. Fast, accessible, and built on OS 2.0 architecture.
02
Shopify Plus Development
Enterprise-grade Shopify builds with checkout extensibility, custom B2B pricing flows, wholesale portals, and dedicated Launchpad campaigns.
03
Shopify Store Migration
Migrate from WooCommerce, Magento, BigCommerce, or any custom platform to Shopify, with all products, customers, order history, and SEO equity intact.
04
WooCommerce to Shopify
The migration we run most often. Move from the complexity of WordPress + WooCommerce to the reliability of Shopify, without losing a single product, review, or ranking.
05
Subscription & DTC Commerce
ReCharge, Bold Subscriptions, or native Shopify subscriptions, set up, tested, and with dunning management and pause/skip flows that protect your MRR.
06
Custom Shopify App Development
Bespoke Shopify apps for checkout logic, loyalty programmes, B2B pricing tiers, or any feature that off-the-shelf apps can't handle cleanly.
07
Shopify Speed Optimisation
Core Web Vitals audit, image pipeline, theme code reduction, and third-party app cleanup so your store loads faster, ranks higher, and converts more.
08
Shopify Ongoing Support
Theme updates, new product collections, app installs, discount logic, and a direct line to the developer who built your store.

FAQs
Common
questions.
Do you build from scratch or customise existing Shopify themes?
We build custom themes from scratch. We avoid editing stock themes like Dawn directly because it creates a maintenance nightmare when Shopify updates them. We build on the OS 2.0 architecture for future-proof block editing, but every visual element is custom to your brand.
Can you migrate our existing store to Shopify?
Yes. We've migrated stores from WooCommerce, Magento 1 & 2, BigCommerce, Wix Stores, and custom-built platforms. Products, variants, customers, order history, and all 301 redirects are migrated safely, your SEO rankings are protected.
Do you work with Shopify Plus?
Yes. Shopify Plus gives you access to checkout extensibility (checkout UI extensions), Scripts (now Functions), B2B wholesale portals, multi-store expansion stores, and Launchpad. We build all of these.
How much does a Shopify store cost?
A custom Shopify store from WebAnts starts from around £3,000 for a lean DTC store. A full custom Shopify Plus build with B2B, subscriptions, and custom apps typically starts from £10,000. Flat quote after a free discovery call.
How long does a Shopify build take?
A standard Shopify store takes 3–5 weeks. A Shopify Plus build with custom apps takes 5–8 weeks. A WooCommerce migration to Shopify takes 2–4 weeks depending on catalogue size and order history volume.
Shopify vs WooCommerce: which ecommerce platform should I choose?
Shopify is a hosted platform — your store runs on Shopify infrastructure with automatic updates, security patches, and a 99.99% uptime SLA. WooCommerce is self-hosted on WordPress, giving more flexibility but requiring you to manage hosting, security updates, and plugin compatibility yourself. Shopify is better for pure ecommerce businesses wanting reliability and simplicity. WooCommerce is better for businesses already on WordPress, those needing complex content alongside their store, or those requiring deep customisation at a lower recurring platform cost.
What are Shopify transaction fees?
Shopify charges transaction fees of 2% (Basic), 1% (Shopify plan), or 0.5% (Advanced) on each sale when using a third-party payment gateway. These fees are waived if you use Shopify Payments. Shopify Plus has a negotiated rate starting at 0.25%. Monthly plan costs range from £25 (Basic) to £2,300+ (Plus). WebAnts sets up Shopify Payments for all UK clients as standard to eliminate transaction fees from day one.
Can you build Shopify for B2B wholesale?
Yes. Shopify Plus includes a native B2B portal for wholesale orders with custom pricing per customer, purchase orders, payment terms, and minimum order quantities. For merchants on standard Shopify plans, we build B2B functionality using wholesale apps or customer tag-based price tiers. We advise on the right approach based on your order volume and buyer complexity.
What is Shopify OS 2.0 and why does it matter?
Online Store 2.0 (OS 2.0) is Shopify current theme architecture, introduced in 2021. It enables sections and blocks on all pages (not just the homepage), JSON templates, app extensions in checkout, and a much cleaner structure for custom theme development. All WebAnts Shopify themes are built on OS 2.0 for future-proof compatibility with Shopify editor updates and the latest checkout extensibility features.
Do you integrate with Klaviyo, ReCharge, or other Shopify apps?
Yes. We integrate all major Shopify apps including Klaviyo, ReCharge, Bold, Judge.me, Loox, Okendo, Yotpo, Gorgias, and any app with a Shopify partner integration. We also advise on which apps you actually need, many stores are over-appd.
