What we ship
The commerce build, end to end
Storefront to checkout to store floor: everything that lifts conversion and AOV, shipped by one senior pod.
01 / 06Headless storefronts
Fast, locale-aware product pages on Shopify Hydrogen or Commercetools, with variants, reviews, and add-to-cart tuned to convert.
Checkout & payments
Mobile-first, smart-routed checkout with card and wallet options: card data never touches your servers.
Personalisation engines
Curated catalogues, recommendations, and mobile discovery, with uplift proven against a permanent holdout.
Merchandising & catalogue
A retail SaaS control plane wiring catalogue, sales analytics, and orders to SAP and Shopify: richer data that lifts AOV.
Order & inventory (OMS)
One inventory truth across every store: per-SKU stock levels, statuses, and reconciliation in a single view.
Subscription & loyalty
Subscription plans, billing history, and saved payment methods, built for lifetime value.
Why our engineering converts
The disciplines behind every uplift
Retail engineering is judged against counterfactual revenue. We build with the rigour to defend it, and the discipline regulated payments demand.
01
Incrementality, not vanity CTR
Holdout cohort, A/B harness, and significance gates before any model ships. Every uplift number is defended.
02
Performance as a budget
Core Web Vitals budgeted in CI: sub-1s LCP on edge-rendered product pages, because every 100ms is measurable conversion.
03
PCI scope, minimised
Card data tokenised at the PSP, never on your servers. Segmented PCI environments only where in-store PAN handling needs them.
04
One inventory truth
An OMS wired to ERP and WMS with stock cached at the edge: sub-200ms lookups at peak, per-SKU reconciliation alerts.
Where it pays off
Where it pays off in production
Selected programmes across omnichannel retailers, multi-brand groups, marketplaces, and D2C brands, anonymised where required, specific on the outcome.

Who we are
About usBritonOne Technology is a full-cycle engineering company that builds and operates production software for regulated estates. Since 2017, we have shipped programmes that clear audit on the first pass across banking, insurance, wealth, healthcare, and biotech. Our teams pair deep domain knowledge with disciplined engineering, treating compliance, security, and resilience as first-class deliverables. From architecture through to live operations, we stay accountable for the systems we build, measuring success by uptime, audit outcomes, and defensible business results.

Why teams choose BritonOne Technology
Four reasons enterprise buyers come back
We don't compete on lowest day-rate. We compete on shipped outcomes inside environments that have to clear audit.
Senior-only delivery
Every engineer on every engagement is at least senior, typically eight to fifteen years deep in their craft. No bench rotations, no junior pyramid hidden behind a glossy proposal, no bait-and-switch after contract signature. The architect who scoped your engagement is the same person committing code by week three.
Audit-ready by default
FCA, PRA, EBA, BaFin, FINMA, HIPAA, SOC 2 Type II: every framework we work under is treated as a design constraint from day one, not a final-stage gate. Evidence trails, model-risk packs, change-control artefacts, and pen-test reports ship alongside the code, ready for second-line review without a remediation sprint.
Anti-drift delivery discipline
Small pods of three to seven engineers, each with a named delivery lead who owns scope, schedule, and outcomes from kickoff to hand-off, never a faceless team you have to chase for an answer. Weekly demos run against the signed scope, frequent verification gates catch regressions early, and quarterly outcome reviews measure real progress against the original business case rather than a moving target. Together those rituals catch scope drift before it has any chance to compound, so programmes that should take six months don't quietly stretch into eighteen, budgets stay anchored to what was agreed, and every milestone ships with a written, testable definition of done that both sides sign off before we move on.
Long-tail support beyond hand-off
We don't disappear the moment the engagement closes. Managed services, hypercare windows, named on-call rotations, or quarterly health checks: pick the depth that matches your operational risk profile. About seventy percent of clients return for a second programme, usually because the team that shipped the first one is still on the other end of the page.
Retail client reviews
What commerce teams say
Anonymous under MNDA. Each quote is from a senior commerce buyer who owned the engagement end to end.
An Uplift We Can Defend
“BritonOne Technology is the only consultancy that refused to ship the personalisation engine without a permanent holdout cohort. That discipline is the difference between an uplift we can defend and one we can't.”

Shopify Plus vs Commercetools vs Adobe Commerce, what's the call?
Workload-dependent. Shopify Plus wins on time-to-market and operational simplicity (best for D2C up to ~£50M ARR). Commercetools wins on composability and bespoke flexibility (best for £50M–£500M omnichannel). Adobe Commerce wins where you already live in the Adobe Experience Cloud. We recommend on your operating model, not vendor preference, and we have shipped on all three.
