Ecommerce software development
use cases
Standard platform features cover a lot. Custom development pays off when they can’t support your business rules, integrations or growth.
Typical situations where ecommerce software development delivers the most value:
-
Bespoke architecture for unique business models
You sell across several storefronts, brands, regions or channels, or mix B2B and B2C, and standard setups limit you.
-
Custom business logic
Your tiered pricing, quotes, contract catalogs, approvals or subscription rules no longer fit plugins and workarounds.
-
Unique checkout, pricing, and promotions
Your buying process is a competitive advantage: multi-step checkout, volume discounts, bundles, loyalty redemption or one-click B2B reorder.
-
Custom catalog and product management
Product configurators, attribute-heavy catalogs, compatibility filters, variant logic or dynamic pricing need more than standard catalog tools offer.
-
ERP, PIM, OMS, and CRM integrations
Stock, orders, customer data and product content must move reliably between your store and the systems that run your business.
-
Scalability, flexibility,
and ownershipYou want a codebase you control, with no wait for a vendor’s releases and no feature gaps limiting your roadmap.

This helps CTOs and Fractional CTOs stay strategic while having a reliable team to execute.

Ecommerce website development
within software delivery
The storefront is where customers meet your software.
We build it for conversion and speed, not just looks.
We deliver:
-
01
Storefront development
Product and category pages, search, cart and checkout, built from clean components your team can maintain and extend.
-
02
UX and UI design
User-centric design that reflects your brand, reduces friction and is checked against how shoppers actually buy.
-
03
Responsive frontend implementation
Fully responsive builds for mobile, tablet and desktop, with special attention to mobile checkout performance.
-
04
Theme customization
We extend platform themes to match your brand and features, without technical debt that complicates future updates.

Checkout flow, product page structure, cross-sell and upsell placement, and trust signals designed to reduce cart abandonment.

06
Speed, core web vitals, and SEO-friendly implementation

Typical project scope
Dinarys works across all four layers, taking full ownership or coming alongside your existing team:
-
01
Storefront
Product catalog, search, product pages, cart, checkout and customer accounts: the layer where shoppers decide to buy.
-
02
Backend
Order management, pricing rules, inventory logic, promotions and APIs. Its quality sets the ceiling for your storefront.
-
03
Integrations
ERP, PIM, OMS, CRM, payments, shipping and marketplaces. They decide how accurately your store reflects your business.
-
04
Architecture
Tech stack, data model, API design, caching, hosting, deployment. Early decisions here shape performance, cost and maintainability.
Ecommerce platforms we work with
-
Adobe Commerce (Magento)
Complex B2B and B2C environments with sophisticated catalog, pricing, and integration needs. Custom modules, performance optimization, and multi-site architecture.
-

02
Complex multi-party or multi-tenant transaction models
-

Marketplace & P2P
Multi-vendor platforms. Seller onboarding, commission logic, escrow, trust systems, and the infrastructure to support multiple parties transacting in one place.

Replatforming and migration
Done poorly, migrations cause data loss, SEO drops and downtime. We plan, test and launch them in controlled stages.

Platform audit
Codebase, data model, integrations, SEO footprint. A clear picture of risk before anything moves.
-
Migration roadmap
A phased plan with milestones, rollback procedures, and go/no-go criteria at every stage.
-
Data migration
Catalogs, customer records, order history, content and media, transferred and checked against the source.
-
SEO continuity
All redirects mapped in advance, implemented on launch day, rankings monitored post-launch.
-
Integration preservation
Every connected system documented and rebuilt or reconnected as part of the scope.
-
Minimum-downtime launch
Blue-green deployment and a staged cutover to keep customer-facing disruption to a minimum.

FAQ
Storefront and frontend, backend business logic, platform setup and custom modules, ERP, PIM, OMS, CRM, payment and shipping integrations, infrastructure, performance and ongoing support. Most projects combine several of these.
When standard platform features can’t support your pricing, catalog, B2B workflows, integrations or performance needs, and workarounds keep piling up. We check configuration and existing extensions first, then build only the gaps.
Yes. We build and maintain connections to ERP, PIM, OMS and CRM systems, payment gateways, shipping providers and marketplaces, and test how each one handles failed or repeated data transfers.
Yes. We can own the storefront and the backend behind it: business logic, APIs, data models, integrations and infrastructure. We also work alongside your in-house team or another partner.
A redesign changes how the store looks. Replatform when the system itself blocks you: performance limits, integrations you can’t maintain, missing B2B or B2C features, or workarounds costing more than migration.
Your current architecture and reusable code, must-have functions, custom pricing or bundle rules, the number of integrations, data quality and support after launch. We separate known costs from open questions.
