Key answer: We build online stores that sell: on WooCommerce, PrestaShop, Shopify or as custom platforms. With considered UX, serious data analytics and conversion optimisation from day one.

E-commerce is a system, not just a store
A store that sells is more than a product catalogue with a cart. It is a system of connected vessels: loading speed affects Google rankings, product-page UX affects conversion, category architecture affects visibility, and analytics affect every business decision. We design e-commerce as one system, because any one of these elements can undo the work of all the others.
Problems we solve
- Traffic without sales: we audit the purchase path, fix cart and product-page UX, and validate changes with A/B tests instead of hunches.
- The store is invisible in Google: we restructure categories, descriptions, product structured data and performance.
- Nobody knows what works: we implement e-commerce analytics that show profitability per channel, product and campaign.
- The platform blocks growth: we migrate to more flexible solutions without losing SEO equity or order history.
How much does an online store cost?
A store on WooCommerce, PrestaShop or Shopify with a custom storefront typically costs €6,000–17,000; bespoke platforms start at around €20,000. On top come running costs: hosting or platform subscription, payments, technical care. Before you sign anything, we lay the whole thing out over three years, so you compare the real cost of ownership rather than the build price alone.
What we actually do
WooCommerce, PrestaShop and Shopify implementations
For most companies an established platform is the fastest route to revenue. We design a custom storefront (no off-the-shelf themes), configure payments, shipping and taxes, and integrate inventory and accounting systems. You receive a complete store: fast, secure and ready to scale.
Custom e-commerce platforms
When processes are non-standard – B2B sales with individual price lists, product configurators, subscriptions, ERP integrations – we build tailor-made platforms on a modern headless stack, with full control over every step of the buying experience.
Data analytics and conversion optimisation
We track the entire funnel: entry, product page, checkout. We analyse where customers abandon carts and systematically test improvements. CRO at Sweet Lava is a data-driven process: heatmaps, session recordings, A/B tests. AI helps us with the analyses, but the conclusions and decisions belong to people who know your business.
Store migrations
We move stores between platforms preserving products, customers, order history and – crucially – Google rankings. Every URL gets a mapped 301 redirect, so changing platforms does not mean losing traffic.
How we work together
- Business analysis: catalogue, margins, logistics, current performance.
- Store architecture: category structure, purchase path, integration list.
- Design: a custom, on-brand storefront optimised for conversion on mobile and desktop.
- Implementation: development, payments, shipping, integrations, load and security testing.
- Analytics: full e-commerce tracking, reports, conversion goals.
- Growth: after launch we analyse data and systematically raise conversion and average order value.
Why Sweet Lava
We combine competencies that rarely come together in e-commerce: shopping-experience design, solid engineering and data analytics. A small senior team means the same people work on your store from the first call to post-launch support.
