Commerce systems that hold up on the busiest day.
Storefronts and checkouts engineered for peak traffic, stock that cannot oversell, catalogue and product-feed systems that scale, and the technical SEO that faceted navigation usually destroys.
The Problems We Actually Get Called About
Retail engineering failures are almost always concentrated in three places: stock, checkout, and the day traffic spikes.
Overselling On The Last Unit
Two customers reach checkout for the same final item. Without a reservation with a time limit, the order is created and the refund is your customer service problem.
The Site Falls On Launch Day
Autoscaling the application is not the same as surviving a real peak. Cold starts, cache stampedes and unindexed queries are what actually break.
Catalogue Complexity
Variants, bundles, size guides, regional pricing and tax, marketplace and direct channels. The catalogue model is the actual product.
Checkout Leakage
Every extra field, redirect, wallet exclusion and step costs completed orders. Address forms that fail validation silently are a top cause.
Parameter Explosion In Search
Faceted navigation generates near-infinite URLs. Crawled and indexed carelessly, they burn crawl budget and let duplicate content outrank your category pages.
Feed And Marketplace Operations
GTIN and UPC mapping, taxonomy mismatches, image licensing rules and disapproval notices. Channel compliance is a recurring operational cost.
What We Build Here
Commerce touches every module, which is why retail engagements are usually our broadest scopes.
BUILD: Commerce Core
Storefront, cart and checkout, stock reservation and reservation expiry, order management, returns, and incremental product-feed generation to every channel you sell on.
DESIGN: Product And Checkout
Category and product page information architecture, size and variant presentation, a checkout that explains itself, and a design system shared with the brand site.
GROW: Discoverability And Demand
Technical SEO for large catalogues, feed-driven shopping visibility, lifecycle journeys for browse and cart intent, and structured CRO on the paths that produce revenue.
Constraints And Where We Stop
Retail has a surprising amount of legal and financial surface area. None of it is ours to adjudicate.
PCI DSS Scope Is Not Ours
Where card data touches your systems determines your PCI DSS scope, and hosted fields or embedded components exist to keep that scope small. We integrate a processor you choose. We do not scope, assess or attest PCI DSS. Your acquirer and a qualified security assessor do that.
Tax, Duty And Facilitator Rules
VAT, sales tax, IOSS and marketplace facilitator obligations are legal and accounting determinations. We implement the rules you and your accountant specify, correctly and testably. We do not advise on which rules apply.
Accessibility Is Usually Obligatory
Online storefronts are commonly required to meet WCAG conformance levels, and consumer protection regimes treat accessibility as a legal duty. We build and test to a stated WCAG level, including keyboard paths and screen-reader passes. The conformance determination and any accessibility statement are yours to make.
Fulfilment And Returns Stay With You
Warehousing, picking, shipping and physical returns are operations, not software. We build the software that records and triggers them, including RMA and refund-to-original-tender logic, but we do not run a logistics operation.
Technical Decisions That Matter Here
The order and inventory path is the part of a commerce system that must be correct. Everything else can be iterated.
Reservation, Not Counting
Stock is reserved at basket or checkout with a time limit and released when it expires. A decrement-and-hope counter is where overselling starts.
The Payment Webhook Is The Truth
Order state follows processor webhooks, not the browser return. The client is told what it is told; the server reconciles against signed events with idempotent handling.
Prices Computed Server-Side
Cart and order totals are recalculated on the server from current catalogue, promotion and tax inputs. Client-side totals are display only.
Caching That Knows What Not To Cache
Catalogue pages cache at the CDN with stale-while-revalidate. Cart, checkout and account pages never cache. Getting this boundary wrong is how pricing leaks.
Feeds Are Incremental
Large catalogues generate product feeds incrementally from a change log rather than rebuilding from scratch on a schedule. Include and exclusion rules are versioned.
A Crawl Policy For Filters
Decided in writing: which parameters are linkable, which are canonicalised away, which are noindex, and how pagination and sort are handled. This is written before the templates are built, not after.
Mapped To Real Services
Every capability below is an existing WebNuvexa service page.
➤ E-Commerce Development — Storefront, cart, checkout, and the order pipeline behind them.
➤ Web Development — Product detail and category templates with real performance budgets.
➤ API Development — Inventory, pricing and order services, plus webhook fan-in from channels.
➤ Custom Software — Stock reservation, returns handling, and back-office operations tooling.
➤ Mobile App Development — Native store apps and responsive storefronts for on-the-go purchase.
➤ Legacy Modernization — Getting off a platform, theme or plugin stack that cannot be safely upgraded.
➤ DevOps & Cloud — Capacity planning, load testing, CDN strategy and zero-downtime deploys.
➤ Technical SEO — Crawl control, canonicals and pagination for faceted navigation.
➤ SEO — Category, collection and editorial content strategy for non-brand demand.
➤ Conversion Rate Optimization — Product page and checkout testing against a defined add-to-cart and checkout-completion rate.
➤ Paid Advertising — Shopping feed campaigns, retargeting and always-on brand defence on category terms.
➤ Email Marketing — Browse, cart and post-purchase flows, with consent and unsubscribe handled properly.
➤ Marketing Automation — Segmented replenishment, back-in-stock and abandoned-checkout journeys.
➤ UI/UX Design — Product page, checkout and mobile-first search interface design.
➤ Design Systems — One catalogue component library across brand site, storefront and internal tools.
➤ Brand Identity — Identity that survives being applied to packaging, marketplace and storefront.
➤ Motion Design — Motion used for state feedback, not decoration, and disabled under reduced-motion.
➤ Maintenance & Support — Seasonal readiness, dependency currency and incident response around peaks.
Indicative Engagement Shapes
Illustrative fixed-fee phase structures only. Not a quote and not a schedule.
Catalogue And Platform Audit
Current platform, catalogue complexity, channel mix, traffic shape and integration inventory. The output is a migration or rebuild recommendation with the reasoning written down.
Core Build
The main fixed-fee tranche: storefront, cart, checkout, order management and the inventory path, with the crawl policy designed in from the first template.
Peak Readiness
Load testing against a realistic traffic profile, caching and CDN configuration, deploy rollback, and a named runbook for launch weekend.
Seasonal Support
A separately priced retainer covering peak preparation, ongoing iteration, feed and channel maintenance, and CRO work after live data exists.
Who This Is Not For
Better to know before a proposal than after.
No Fulfilment Capability
We build commerce software. If nothing physically ships, picks or returns, the hard half of the business is still unsolved.
Marketplace Without A Facilitator
Selling on a marketplace that requires a licensed facilitator relationship is a commercial and legal negotiation first. We build the software around the agreement you have.
Chasing A Conversion Guarantee
We do not publish conversion guarantees or uplift percentages. We will tell you what we think the constraint is and what we would test.
Zero Engineering Involvement
Commerce systems accumulate catalogue, tax, returns and channel exceptions indefinitely. Someone on your side has to own the rules we implement.
