eCommerce & Retail Software Development

Industry challenges we solve

Retail margins are thin and the difference between a profitable store and a closed one is often a 200ms page weight, a misrouted refund, or a stock count that lied. We focus on the things that move the funnel.

Page speed kills conversion. A bloated theme, twelve marketing pixels, and an unoptimized hero image push Largest Contentful Paint over 3 seconds. Mobile bounce climbs, paid traffic loses 20% of its yield, and Core Web Vitals tank organic.

Inventory drifts between channels. The website oversells a product that the warehouse already shipped to wholesale. Customer service apologizes, refunds the order, and the brand pays for the marketing twice.

Abandoned cart automation that nobody trusts. Email sends 90 minutes after abandonment, the discount is too generous, margin gets eaten, and customers learn to wait for the discount before completing checkout.

Search returns nothing for half the queries. No synonym dictionary, no typo tolerance, no personalization. The user types "trainers", the catalog calls them "sneakers", the search bar shrugs, the sale walks.

Payments charge more than they should. A single PSP routes every transaction at standard rates. No 3DS exemption logic, no smart routing between acquirers, no local method support. The blended cost of payments creeps past 3%.

ERP integration that breaks every Tuesday. A flat file CSV runs on a cron job. The mapping changes when finance adds a new product attribute. Orders pile up unsynced and the warehouse waits for an email confirmation that never comes.

Marketplace & B2B platforms

Multi vendor marketplaces with split payments via Stripe Connect, Adyen for Platforms, or Razorpay Route. Vendor onboarding with KYC, per vendor inventory and shipping, dispute handling, and DAC7 reporting where applicable. B2B portals with quotes, approvals, and account hierarchies.

Compliance & regulatory considerations

Retail compliance is light compared to fintech, but the small obligations add up: PCI for card data, sales tax in every US state, distance selling rights in the UK and EU, and the new platform reporting regimes that catch marketplaces unaware.

PCI DSS v4.0 (scope reduction) GDPR & UK GDPR CCPA / CPRA UK Consumer Rights Act EU Consumer Rights Directive DAC7 marketplace reporting US state sales tax (Avalara, TaxJar) UAE VAT (5%)

PCI DSS is solved by avoiding it. The cheapest compliant store is the one whose servers never see a card number. We push tokenization into Stripe Elements, Adyen Drop-in, Checkout.com hosted fields, or Razorpay's standard checkout, and audit every log line that could accidentally capture sensitive authentication data. The result is SAQ A scope rather than SAQ D, which translates to a self attestation rather than a four week audit program. For subscription products that need vaulted card data, we isolate the cardholder data environment and use processor managed vaults rather than rolling our own.

UK and EU consumer law shapes the checkout, not just the legal page. Distance selling rights mean clear cancellation flows, refund timers that do not exceed 14 days, and unambiguous "buy now" buttons. The EU Consumer Rights Directive applies to digital goods too, and the latest Geo-blocking Regulation forbids redirecting EU customers between country stores without consent. We bake these constraints into the checkout flow rather than bolting them on with disclaimer text.

Marketplaces face a new reporting regime. DAC7 in the EU and the equivalent UK regulations now require platforms to collect, verify, and report seller information annually. We build the data collection flow into vendor onboarding, validate VAT numbers and tax residency at sign up, and produce the XML reports HMRC and EU member state authorities expect. US state sales tax via Avalara or TaxJar handles nexus thresholds that move every year.

Tech stack we use for eCommerce & retail

Boring infrastructure where it lets us move faster. The interesting code is in payments, search, and the integration boundary, not in reinventing the storefront.

Retail / DevOps Transformation 120 store UK retail chain · 10 weeks · 4 engineers

Retail platform DevOps transformation: from monthly Sunday night releases to daily deploys

A 120 store UK retail chain with a growing ecommerce operation shipped to production once a month in a Sunday night maintenance window: SSH into bare metal, pull code, run migrations, restart services, with tar backups as the rollback plan. Two of the last six releases had caused 2 to 4 hour partial outages, and Black Friday traffic routinely overwhelmed a single Nginx front door. We dockerized the five services without rewriting them, moved them onto EKS provisioned with Terraform, built GitHub Actions pipelines with a production approval gate and automatic rollback on failed health checks, and added Prometheus, Grafana, Loki, and Jaeger with PagerDuty alerting. Daily deploys became normal, the pipeline dropped from 3 hours to 12 minutes, the storefront now autoscales from 3 to 30 pods for peak trading, and the team finally had time to ship the headless storefront they had been promising.

FAQ

Common questions

Should we go headless or stay on a monolithic platform like Shopify or Magento?

It depends on your conversion ceiling and team. Shopify Plus and Adobe Commerce (Magento) get you to market fast and handle PCI for you. Headless commerce on Medusa, Saleor, or commercetools wins when your storefront performance, content velocity, or omnichannel surface area starts to bottleneck. Our usual answer for D2C brands under $20M GMV is to stay on Shopify and harden the theme. Above that, or when a native app and a kiosk and a website all need the same catalog, headless usually pays for itself within a year.

Can you keep us out of PCI DSS scope?

Usually yes. The cleanest path is to never let card data touch your servers: Stripe Elements, Adyen Drop-in, Checkout.com hosted fields, or Razorpay's standard checkout tokenize the PAN inside the processor's iframe. Your application only ever sees a token. That keeps you in PCI DSS SAQ A territory and avoids the four week SAQ D audit program. Where you genuinely need vaulted card data for subscriptions or one-click checkout, we isolate the cardholder data environment with network segmentation and short-lived credentials.

Can you integrate our store with SAP, NetSuite, or another ERP?

Yes. We have built bidirectional sync layers between Shopify, Magento, and headless storefronts and SAP S/4HANA, NetSuite, Microsoft Dynamics 365, Odoo, and bespoke ERPs. The hard problems are not the API: they are reconciliation when an order, an invoice, and a stock move drift apart. We design idempotent message flows on Kafka, RabbitMQ, or Azure Service Bus, with a reconciliation dashboard and replay tooling so finance can fix a bad day without engineering.

Do you build search and recommendations engines that actually convert?

Yes. Our default is Algolia or Elasticsearch for search, with synonym dictionaries, typo tolerance, and personalization rules tuned to your product taxonomy. For recommendations we use a mix of collaborative filtering, content based scoring, and LLM driven semantic similarity for cold start products. We measure with click through rate, add to cart rate, and revenue per session against a holdout, not vanity dashboards. The honest answer is that an 8 to 12% revenue lift is achievable on most catalogs; anything beyond that depends on your baseline.

Can you build a multi vendor marketplace platform?

Yes. We have built marketplace platforms on Medusa with custom vendor logic, on Saleor, and from scratch on Node.js plus PostgreSQL. The core problems are split payments (Stripe Connect, Adyen for Platforms, Razorpay Route), per vendor inventory and shipping rules, vendor onboarding with KYC, and dispute handling. We also handle the consumer law obligations: UK distance selling, US state sales tax via TaxJar or Avalara, and the EU DAC7 reporting where it applies.

How fast can a new D2C storefront go live?

A focused D2C storefront on Shopify with custom theme, payments, ERP sync, and abandoned cart automation typically ships in 6 to 8 weeks with a 3 person team. A headless build on Medusa or Saleor with a Next.js storefront, search, and a back office takes 10 to 14 weeks. Marketplace platforms run 14 to 20 weeks for a credible v1. AI agents handle scaffolding, schema migrations, and tests; senior engineers own performance, payments, and the integration boundaries.
