eCommerce and Retail Software Development for Commerce Platforms

Commerce systems built for peak day, not launch day.

DigiWagon builds storefronts, order and inventory systems, loyalty and personalization platforms and the integrations behind them for retailers, D2C and B2B brands, marketplaces and consumer-goods companies in the United States, the United Kingdom and India. Every platform is engineered for the peak-day order and the returns desk, not just the launch.

What Does Your Commerce Platform Have to Prove?

Pick the situation closest to yours. We’ll show what we would build for it, where it sits in the commerce services below, and which rule shapes it.

Pick what your platform has to prove

What it has to prove

A Storefront That Buckles on Peak Day

The site is fine at Tuesday traffic and falls over on the promotion the marketing team forgot to mention, checkout errors spike, and nobody can say whether it was the search service or the payment provider.

What we would build
What you could end up with
  • A storefront that renders fast on a phone on a bad connection
  • Checkout tested against the peak the plan expects, not the average
  • Catalog, pricing and promotions as data merchandisers change without a release
What it works with
  • Your commerce engine, PIM and payment providers
  • CDN, search and media services
  • Marketing, analytics and consent tooling
What it has to prove

Inventory the Store, the Site and the Warehouse Disagree On

The site sold what the shelf did not have, the store cannot see what the warehouse holds, and the promise date was made by a system that never asked either of them.

What we would build
What you could end up with
  • One inventory position across stores, warehouses and 3PLs, updated as events
  • Order orchestration that picks the cheapest promise you can keep
  • Returns and exchanges built into the order, not bolted on
What it works with
  • Your ERP, POS and WMS
  • 3PL, carrier and marketplace feeds
  • Customer service and finance
What it has to prove

Customers You Recognize in One Channel and Not the Other

The loyalty member in the store is a guest on the site, the app knows a different address, and marketing sends an offer for a product the customer returned last week.

What we would build
What you could end up with
  • One customer profile across store, site, app and marketplace
  • Loyalty and offers that respect consent and margin
  • Segments and lifetime value the merchandiser can act on
What it works with
  • POS, commerce and CRM systems
  • Consent and preference records
  • Marketing automation and support
What it has to prove

A Platform Migration Nobody Wants to Own

The platform is end-of-life, the customizations cannot be upgraded, and every proposal to move it is a proposal to risk the rankings, the orders and the customer accounts at once.

What we would build
What you could end up with
  • A migration plan with URL, SEO and order continuity as first-class requirements
  • Capabilities moved one at a time behind a routing layer
  • A rollback position at every step
What it works with
  • Your current platform, data and integrations
  • Search, marketing and analytics tooling
  • The teams who run the store today

What we build

Commerce Software Services

Retail and ecommerce software for the storefront, the store and the back office, from an ecommerce software development company that has built for both: the storefronts, order systems, customer platforms and integrations below, each linked to the DigiWagon practice that builds it. Retail software development here means the systems a retailer runs; ecommerce software development means the ones a customer touches; most programs need both.

01

Retail & Commerce Digital Strategy

Most commerce programs fail on the eleventh promotion, not the first: the platform assumed a catalog that does not change weekly, an order flow that never splits, or a returns rate the business case ignored. Discovery starts with how the business actually sells — channels, margins, promotions, fulfillment promises, returns — and settles the sequence: what to build, what to buy, what to integrate, what to retire. The output is a roadmap costed against conversion, cost to serve and peak-day risk, and a first release the teams will use.

02

Headless Storefronts & Commerce Platforms

Storefronts built as fast, accessible front ends over a commerce engine, so the experience changes at the pace of marketing and the engine changes at the pace of finance. Catalog, pricing, promotions and content are modeled as data merchandisers edit without a release; checkout is instrumented, tokenized and tested against the peak the plan expects; and search, media and consent are integrated rather than pasted in.

03

B2B Commerce Portals & Marketplaces

Account-specific catalogs and pricing, quotes, approvals, credit terms, punch-out and bulk ordering for distributors and manufacturers selling to businesses, and multi-vendor marketplaces where the platform owns the buyer relationship and the vendors own the stock. Contract pricing and entitlements are data with effective dates; orders flow into the ERP with the references finance needs; and vendor onboarding, catalog ingestion and settlement are built as product features.

04

Retail Mobile Apps & In-Store Digital

Shopping apps, loyalty wallets, click-and-collect, scan-and-go, store associate tools and kiosk experiences built for the aisle and the queue, not the boardroom demo. Apps share the same catalog, inventory and customer services as the storefront, so a price or a stock position is never different on the phone. For a multi-brand service network we built the consumer web and mobile platform for booking, real-time tracking and workshop coordination in several languages — service tracking 50% faster, coordination 40% smoother — the same pattern a retail chain’s customer app and store tools follow.

Mobile App Development

05

Order, Inventory & Fulfillment Systems

Order management that orchestrates every channel’s orders against one inventory position, chooses the fulfillment node that keeps the promise cheapest, and handles splits, backorders, exchanges and returns as part of the order rather than as exceptions. Inventory is a stream of events from stores, warehouses and 3PL partners, reconciled to the ERP, so the site never sells what the shelf does not have. Returns and reverse logistics are designed in from the start, because a retailer’s margin is decided as much at the returns desk as at checkout.

06

POS, ERP, Payments & Logistics Integration

A retailer’s stack is a dozen systems that were never introduced to one another: POS, ERP, WMS, payment providers, tax engines, carriers, marketplaces, loyalty, support and marketing. We build the integration layer that makes them one flow — event-driven, idempotent so a retried webhook never duplicates an order, with dead-letter queues and monitoring that tells you a feed stopped before customers do. Payments are integrated through tokenizing providers, so card data never touches your systems and the PCI DSS scope stays narrow, and tax, shipping and marketplace connectors onboard by configuration.

07

Customer Data Platforms & Loyalty

One customer record across store, site, app and marketplace, built on a governed data layer with consent, preferences and lawful basis attached to every attribute, so recognition is a service you offer rather than a surveillance the regulator asks about. Loyalty programs, tiers, offers and gamified rewards run as configuration on that record; lifetime value, churn and segment analytics run on the same data, so marketing and finance read the same numbers.

08

Personalization, Search & Recommendations

Recommendation, search ranking, next-best-offer and dynamic merchandising models trained on your own browsing, purchase and inventory data and constrained by margin, stock and consent. Every model ships with documented features, an offline and an online evaluation, guardrails for the products it must never promote, and monitoring for drift and for the fairness questions a regulator may ask. The retail data analytics behind it — which products convert, where journeys break, what a segment is worth — runs on the same governed layer, so the model and the dashboard never disagree.

09

Retail Analytics & Demand Forecasting

Sell-through, margin, stock cover, promotion lift, basket and channel analytics calculated once and read the same way by merchandising, stores, e-commerce and finance, with lineage from the dashboard back to the transaction. Demand and replenishment forecasts by store and SKU sit on the same data, so the forecast and the actual it is compared against come from one source. For a global consumer-goods company we built a knowledge platform over millions of documents for R&D and compliance teams — information 70% faster to find — and the analytics discipline is the same.

Product Education & Content Experiences

Interactive product hubs, simulators, guided selling and self-serve learning tools that explain a product’s technology to sales teams, partners and customers better than a PDF ever did. For a leading consumer-goods brand we built an interactive web hub that turned its product technology into simulators and self-serve learning, streamlining internal communication and building confidence in the product across teams. The design work is research-led: who needs to understand what, in which moment, on which device, and what confident adoption looks like when it is measured.

Commerce Replatforming & Modernization

Replatforming a store is the migration nobody wants to own, because everything is visible: URLs, rankings, orders, customer accounts, integrations. We do not switch it off and on. URL mapping and redirects, search continuity and order history are first-class requirements; capabilities move one at a time behind a routing layer; each cutover runs in parallel and reconciles before the old path is retired; and there is a rollback position at every step.

Who we build for

Retailers We Build For

Five kinds of seller, each with its own margin, calendar and failure modes. The order, customer and integration patterns transfer between them; the promise made to the customer does not.

Online Retailers & D2C Brands

A storefront, a promise and a returns rate. Fast, accessible storefronts over a commerce engine, subscription and replenishment models, and the order and customer platforms that keep the promise the site made — engineered for the promotion day, not the launch day.

Brick-and-Mortar & Omnichannel Chains

Stores that must now behave like the site: click-and-collect, ship-from-store, scan-and-go, associate tools and one inventory position across the network. Integration with POS and ERP is most of the work, and the customer app is built on the same services as the store.

B2B Distributors & Marketplaces

Account pricing, quotes, approvals, credit and bulk orders for buyers who would otherwise phone, and marketplaces where vendors own the stock and the platform owns the buyer. Portals that buyers prefer to the spreadsheet are the only kind that pay back.

FMCG & Consumer Goods Companies

Products that change fast and knowledge spread across teams and documents. For a leading consumer-goods brand we built an interactive product-education hub with simulators and self-serve learning; for a global one, a knowledge platform that made information 70% faster to find.

Franchise & Multi-Brand Groups

Headquarters needs one view, outlets need autonomy, and the customer expects the same experience under every sign. Multi-tenant platforms, shared catalogs with local pricing, consolidated reporting and loyalty that works across brands — the pattern of the multi-brand service network we built.

Compliance by design

Compliance Is Architecture

Commerce software is judged by rules the customer never sees: how card data is handled, when a payment must be challenged, what a customer must be told before buying, what consent covers, whether the storefront can be used with a screen reader, and which tax applies to which basket. We treat each as a design constraint rather than a badge. Every framework below binds at least one of the services above, because that is where it is implemented.

01

PCI DSS v4.0.1

Card data security for every storefront, app and store system that takes payment; tokenizing providers and hosted fields keep the platform in the narrowest SAQ, and the evidence is produced by the pipeline.

Checkout & paymentsIntegration

02

PSD2 Strong Customer Authentication (EU) and UK SCA; EMV 3-D Secure 2

Two-factor authentication rules for card payments in Europe and the UK, applied through 3-D Secure with exemptions handled, so conversion is not sacrificed to compliance.

Checkout & payments

03

GDPR, UK GDPR, CCPA/CPRA and India’s DPDP Act 2023

Lawful basis, consent, cookies, marketing preferences, profiling limits, retention and subject rights for the customer data a retailer necessarily holds, applied per market.

Customer dataPersonalizationStorefronts

04

WCAG 2.2 Level AA; ADA Title III; the European Accessibility Act (applies from 28 June 2025)

Accessible storefronts, apps and kiosks as a legal duty in the US and Europe and a conversion advantage everywhere; tested with assistive technology, not only with a checker.

StorefrontsMobile appsIn-store digital

05

UK Consumer Contracts Regulations 2013, the EU Consumer Rights Directive and India’s Consumer Protection (E-Commerce) Rules 2020

Pre-contract information, cancellation and returns rights, seller and grievance disclosures for online sales; modeled as data per market rather than as a footer paragraph.

CheckoutReturnsMarketplaces

06

US sales tax after South Dakota v. Wayfair (2018); UK and EU VAT with the OSS and IOSS schemes

Nexus, destination-based rates, marketplace facilitator rules and cross-border VAT collection; handled by a tax engine integrated at checkout and reconciled in the ERP.

CheckoutIntegrationMarketplaces

07

GS1 standards — GTIN, GS1 Digital Link and EPCIS 2.0

Product identification across channels and partners, QR codes that resolve to product data, and the event vocabulary traceability and recall queries are built on.

CatalogInventory & fulfillment

08

CAN-SPAM and the TCPA (US), PECR (UK) and the ePrivacy rules

Consent and opt-out rules for email, SMS and tracking; loyalty and personalization engines read the preference record before they send anything.

LoyaltyMarketing integration

09

ISO/IEC 27001:2022 and SOC 2 Type II

Information security management and evidenced controls. DigiWagon holds ISO/IEC 27001 and ISO 9001 certification; the platform’s pipeline generates the SOC 2 evidence as it runs.

Every engagement

Certification is a claim we make only about ourselves. For everything else on this list, the platform is built for the rule and the evidence is produced with the code.

How we work

How a Commerce Build Runs

Ecommerce software development starts from the order path and the peak calendar, not the feature list: how the business sells and returns, which systems hold the truth, what the promotion calendar will do to load, and what the storefront cannot afford to lose during a change. Everything else is sequenced from there.

01

Discover the Order Path

Follow an order from search to return across every channel and system, read the promotion calendar and the returns data, and map the systems of record before scope is fixed, so the plan is costed against conversion and cost to serve rather than against a demo.

Focus
Order pathChannelsPromotionsSystems of record
02

Design for Peak and Returns

Checkout under the load the plan expects, inventory as events, returns inside the order, consent attached to every customer attribute and accessibility from the first component are designed as features, because retrofitting any of them costs a season.

03

Build Behind the Live Store

New capabilities ship behind a routing layer while the store trades, integrations are certified against sandboxes before a live order touches them, and each cutover runs in parallel and reconciles orders and inventory before the old path is retired.

FAQ

Frequently Asked Questions About eCommerce and Retail Software Development

Direct answers on what a modern commerce platform needs beyond the storefront, how POS, ERP and payment systems are integrated without disrupting trading, how personalization respects privacy law, how a store is replatformed without losing rankings or orders, and what an ecommerce software development company should be able to show you.

01What should a modern eCommerce platform include beyond the storefront?

Order management across every channel, one inventory position updated as events, returns designed into the order, a customer record with consent attached, tokenized payments, tax and shipping engines, and integrations that fail loudly rather than silently. The storefront is the visible tenth; the other nine tenths decide whether the promise the site makes is one the warehouse and the returns desk can keep.

02Can you integrate with our POS, ERP, WMS and payment providers without disrupting trading?

Yes. Integrations are built event-driven and idempotent, so a retried message never duplicates an order, and each one is certified against the partner’s sandbox before a live transaction touches it. Cutovers run in parallel with the existing flow and reconcile orders, payments and stock before the old path is retired. Payments go through tokenizing providers, so card data never enters your systems and the PCI scope stays narrow.

03How do you personalize the customer experience without breaking privacy rules?

By attaching consent and lawful basis to every attribute in the customer record and letting the models read it. Recommendations, offers and messaging respect the preference record per market — GDPR and UK GDPR, CCPA, India’s DPDP Act — profiling is explainable and reversible, and the products a model must never promote are guardrails, not hopes. Personalization built this way converts better, because customers trust it.

04How do you replatform a store without losing SEO rankings and orders?

URL mapping, redirects, search continuity and order history are treated as requirements, not migration chores. Capabilities move one at a time behind a routing layer while the store trades; each cutover runs in parallel and reconciles before the old path is retired; and there is a rollback position at every step. Rankings are monitored through the change, and the release calendar respects the promotion calendar.

05What retail and eCommerce work have you shipped?

One published case study is consumer-goods work: an interactive product-education hub with simulators and self-serve learning tools for a leading consumer-goods brand. The rest of the proof is adjacent and named as such — a consumer web and mobile platform for a multi-brand service network with real-time tracking, paperless onboarding with 98% identity-verification accuracy, and a knowledge platform for a global consumer-goods company. Ask for the detail behind each.
