Sentry's Ecommerce service builds and manages stores on Shopify, WooCommerce, BigCommerce, Magento or a fully headless stack — chosen against your margin model rather than our preference — and engineers them for sub-second pages, search and checkout conversion.

We build on the platform that gives your business the biggest edge, then engineer it to perform: sub-second pages, SEO in the architecture, a checkout tuned for conversion, and every interaction feeding your data. Every service here is available as a project, as monthly support, or as a fully managed service.

## What it does

Engineers modern storefronts for speed, search, conversion and data — edge-served, composable and measured end to end.

## Where it creates value

The point of exchange where the value stream is realised as revenue: marginal gains in speed and conversion here multiply across every order and compound the data that improves everything upstream.

## Why it cannot be ignored

In commerce, milliseconds are money — slow, generic stores haemorrhage conversion to faster rivals on every visit. The loss is invisible per session and brutal at scale: orders you already paid to acquire, walking away.

## What you get

- **The right platform** — Shopify, WooCommerce, Magento, BigCommerce, PrestaShop, Medusa JS or commercetools — matched to your catalogue, team and margins, not sold to you.
- **Composable when it counts** — Headless storefronts in Shopify Hydrogen, BigCommerce Catalyst, Next.js or Astro over Shopify, BigCommerce, Magento (Adobe Commerce), WooCommerce, PrestaShop, Medusa JS or commercetools, with content in Sanity — for maximum speed and design freedom.
- **Migrations in any direction** — Between any of the five platforms, or from OpenCart, Wix, Squarespace or a custom build — products, customers, orders, reviews and every old web address carried across.
- **Payments and shipping** — Stripe, PayPal, Adyen, Klarna, Worldpay, Apple Pay and Google Pay; ShipStation, Royal Mail Click & Drop, DPD, Evri and third-party warehouses.
- **Connected to your business** — Accounts and stock systems, product-information systems, CRM and email marketing, with custom app and API work where no connector exists. We check the order reaches the warehouse and the accounts, not just that the connection shows as working.
- **Selling internationally** — Local currency, translated storefronts that appear in each country's own search results, and local payment methods, tax and duties per market.
- **Themes built for speed** — Custom and adapted themes on every platform, tested for load speed, accessibility and mobile checkout before release.
- **A/B testing, not guesswork** — Product page, basket and checkout changes run as controlled tests, and shipped only once measured against the current version.
- **Monthly support or managed service** — Every service on this page is also available as monthly support — updates, security patches, uptime monitoring, fixes and improvement hours — or as a fully managed service that runs the store's technology and reports measured results monthly.

## Questions and answers

### Which ecommerce platform should we be on?

Whichever gives your business the biggest edge — Shopify, WooCommerce, BigCommerce, Magento, or a headless storefront in Astro or Next.js over any commerce engine. Sentry matches the platform to your margin model rather than selling the one it prefers to build on, because platform fees quietly compound against margin for years.

### Why does store speed matter so much in ecommerce?

Because milliseconds are money. Slow, generic stores lose conversion to faster rivals on every visit, and the loss is invisible per session and brutal at scale — orders you already paid to acquire, walking away. Sentry engineers for sub-second pages because that is where recovered margin actually lives.

### When is headless worth it for a store?

When speed and design freedom are worth more to you than the simplicity of an all-in-one platform. Sentry builds composable storefronts in Astro or Next.js over an existing commerce engine, so the shopfront gets edge performance while the commerce logic stays where your team already runs it.

### Do you handle SEO for an ecommerce site, or is that separate?

It is built into the architecture rather than added afterwards. Search performance, page speed and the data layer are engineered as part of the build, so that every interaction feeds your data and the store is measurable end to end from the day it ships.

### We are already on a platform. Do you have to rebuild the store?

Not by default. Sentry starts with a free Discovery session and a Financial Value Model to establish what your current store is actually producing and where margin is leaking. Rebuilding something that converts is a cost, not a strategy.

### What does managed ecommerce cost?

Sentry's managed services start at £3,000 per month, scoped to the work, with third-party tool costs for the services we manage included up to a fair-use cap; paid advertising spend is excluded. Managed services are priced as a percentage of your annual sales, and the percentage rises with the service level you choose — Protect, Enhance or Create. We confirm the figures in your quote.
