UK WooCommerce development means Klarna integration, ICO cookie consent in WordPress, VAT-inclusive pricing, and getting off shared hosting before the performance issues compound

The Klarna official WooCommerce plugin does not place promotional messaging at the product price by default. Adding it at the price line requires a custom action hook targeting the `woocommerce_single_product_summary` hook position — typically at priority 15 to place it directly after the price — and a call to the Klarna On-Site Messaging (OSM) widget with the correct data-key and data-purchase-amount attributes. The data-purchase-amount must be dynamically populated with the product price in the correct pence/integer format. CSS adjustment is usually required to match the widget appearance to the existing price display. This is a theme development task, not a plugin configuration task.

ICO compliance requires that non-essential tracking scripts — Google Analytics, Google Ads, Meta Pixel, Hotjar, and others — do not load until the user has accepted them. Installing a cookie banner plugin is not sufficient if the scripts still load on page load. The correct implementation either uses a consent management platform that integrates directly with Google Tag Manager consent mode (so GTM fires tags only when the relevant consent category is granted) or uses the cookie plugin's script blocking feature to wrap each third-party script in a consent condition. After implementation, verify compliance by loading the site in an incognito window with network monitoring open and confirming no third-party tracking requests fire before accepting the consent banner.

In WooCommerce, go to Settings > Tax. Set "Display prices in the shop" to "Including tax" and "Display prices during cart and checkout" to "Including tax". Ensure your tax rate is set up correctly under Tax Rates with the standard UK rate of 20% applied to taxable products. Set the "Price display suffix" to empty or to a label such as "inc. VAT" if you want to make the inclusion explicit. Confirm that the base country for your store is set to United Kingdom. If you entered product prices inclusive of VAT when adding products, and WooCommerce was calculating VAT on top of that, you will need to recalculate your product prices after changing the tax display settings — the stored prices and the display setting interact.

There is no official Sage plugin for WooCommerce. Third-party connectors exist (Codeless Platforms, Patchworks) but require configuration and ongoing maintenance. A custom integration uses WooCommerce webhooks to push order data to an intermediary API layer that maps WooCommerce order fields to Sage invoice fields and creates records via the Sage 50cloud API or Sage 200 REST API. The integration needs to handle customer matching (create new Sage customer if the email does not exist, match to existing if it does), product code mapping, tax code mapping, and inventory decrement. Payment reconciliation between WooCommerce and Sage is a separate data flow that depends on whether Sage is being used for bank reconciliation.

For UK WooCommerce stores, managed WordPress hosting with a server location in London or Dublin reduces latency for UK visitors and improves Core Web Vitals scores that affect Google UK rankings. WP Engine (UK data centre available), Kinsta (London region), and Cloudways on AWS eu-west-2 (London) are the three most reliable options for stores processing between 100 and 5,000 orders per month. Shared hosting — including WP Engine's entry-level plans, GoDaddy managed WordPress, and SiteGround's shared plans — does not provide the isolated resources needed for WooCommerce to perform consistently under load. The performance difference between shared and managed hosting becomes measurable on Core Web Vitals reports at around 200 concurrent visitors.
