Custom Ecommerce Development for Scalable Online Businesses
The Runner Software Solutions builds and modernizes ecommerce platforms for B2B distributors, B2C retailers, DTC brands, manufacturers, and enterprise sellers across the United States and Canada. Whether you need a custom storefront built from scratch, a migration off an aging platform, or deeper integration with your ERP and CRM systems, our ecommerce developers design architecture around how your business actually operates — not around a template's limitations. We work with businesses facing real operational friction: slow storefronts that lose customers before checkout, product catalogs too complex for off-the-shelf platforms, inventory that falls out of sync across channels, and checkout flows that don't reflect how B2B buyers actually purchase. Our team designs, builds, integrates, and maintains ecommerce systems engineered for growth, security, and long-term maintainability.

Ecommerce development is the process of designing, building, and maintaining the software systems that power an online store — including the storefront, product catalog, shopping cart, checkout, payment processing, customer accounts, order management, and the backend infrastructure connecting all of it together. Building an online store is not the same as building a complete ecommerce system. A basic store might display products and accept payments. A complete ecommerce system also has to manage:
Ecommerce development sits at the intersection of software engineering, UX design, and business process design. Getting the architecture right early avoids expensive rework later, particularly once a catalog or integration footprint grows.
Custom ecommerce development means building a platform around your specific business logic — pricing rules, catalog structure, checkout flow, and integrations — rather than adapting your operations to fit a pre-built platform's constraints. This approach makes sense when your business has workflows that don't map cleanly onto standard ecommerce software: tiered B2B pricing, configurable products, multi-warehouse fulfillment, or approval-based purchasing.
For consumer-facing stores, we build the components that shape how shoppers discover, evaluate, and buy products: - Customer account creation and login - Product discovery through search, filtering, and recommendations - Product detail pages with variant selection and rich media - Cart and checkout flows optimized for conversion - Payment processing across cards and digital wallets - Promotions, discount codes, and loyalty mechanics - Order tracking and post-purchase communication
B2B ecommerce has fundamentally different requirements than B2C. We build: - Business accounts with multiple linked buyer users - Approval workflows for purchases above defined thresholds - Customer-specific and tiered pricing - Bulk ordering and quick-order tools (SKU/CSV upload) - Purchase order and net-terms payment support - Segmented catalogs based on account type or contract - Account management dashboards for reordering and order history
Enterprise ecommerce platforms need to handle large product volumes, high concurrent traffic, and multiple integrated systems without performance degradation. This includes architecture for complex catalogs, multiple customer segments and roles, ERP and CRM synchronization, and workflow automation across departments.
Marketplace platforms connect multiple sellers to a shared storefront and require distinct architecture: seller onboarding and verification, per-seller product management, commission calculation, order routing, and seller payout processing. Marketplace administration also needs dedicated tooling so platform operators can manage disputes, listings, and seller performance.
Beyond the main storefront, many businesses need dedicated portals: distributor portals with negotiated pricing, wholesale portals with bulk order tools, or partner portals with restricted catalogs and custom permissions. These portals typically share backend infrastructure with the main store but present a distinct front-end experience tailored to that user group.
Modern ecommerce platforms rarely operate in isolation. We build and integrate REST APIs connecting the storefront to ERP systems, CRM platforms, inventory management tools, payment processors, shipping carriers, and accounting software — enabling data to flow automatically instead of through manual entry.
Migrating to a new ecommerce platform involves moving products, customers, order history, and categories while preserving URL structure, redirects, and SEO equity. We plan migrations to minimize downtime and data loss, and validate that search rankings and indexed content transfer correctly to the new system.
Post-launch, ecommerce platforms need ongoing attention: security patching, bug fixes, performance monitoring, integration upkeep as third-party APIs change, and incremental feature development as the business evolves.
Step 1
Business & Ecommerce Discovery — We learn your business model, customer types, existing systems, and pain points. This ensures the technical approach matches actual business needs rather than generic assumptions.
Step 2
Requirements Gathering — We document functional requirements: catalog structure, checkout logic, integrations, user roles, and admin needs. You receive a clear scope before development begins, reducing surprises later.
Step 3
Ecommerce Architecture Planning — We design the technical architecture — database structure, API design, integration points — appropriate to your scale and complexity. This planning phase reduces costly rework during development.
Step 4
UX/UI Design — We design storefront and admin interfaces around usability and conversion principles. You review and approve designs before development, keeping the team aligned on the intended experience.
Step 5
Product Catalog Planning — We structure categories, attributes, and variants to support both customer navigation and backend management at your catalog's actual size.
Step 6
Frontend Development — We build the customer-facing storefront using the agreed technology stack, translating approved designs into functional, responsive interfaces.
Step 7
Backend Development — We build the application logic, database layer, and internal APIs that power the storefront and admin systems.
Step 8
Payment Integration — We connect chosen payment gateways, implement transaction handling, and test failure and edge cases before launch.
Step 9
ERP/CRM/Inventory Integration — We build and test the data connections between your storefront and existing business systems, validating synchronization accuracy.
Step 10
Database Development — We finalize database schema, indexing, and query optimization to support expected traffic and catalog size.
Step 11
QA & Testing — We test functionality across devices, browsers, and user flows, identifying and resolving issues before they reach customers.
Step 12
Security Testing — We review authentication, authorization, input handling, and API security before launch.
Step 13
Performance Optimization — We tune loading speed, caching, and Core Web Vitals metrics ahead of launch.
Step 14
SEO Validation — We confirm technical SEO elements — structured data, canonical tags, sitemap, redirects — are correctly implemented.
Step 15
Deployment — We deploy to production using a controlled release process, minimizing downtime risk.
Step 16
Monitoring — We monitor system health, error rates, and performance immediately post-launch to catch issues early.
Step 17
Continuous Improvement — Post-launch, we support ongoing feature development, optimization, and maintenance as your business evolves.

Ecommerce development is the process of designing, building, and maintaining the software systems that power an online store — including the storefront, product catalog, shopping cart, checkout, payment processing, order management, and backend infrastructure. It covers everything from the customer-facing shopping experience to the administrative tools businesses use to manage products, orders, and customers. Ecommerce development goes beyond simply putting products online; it involves databases, APIs, integrations with business systems like ERP and CRM platforms, security architecture, and performance engineering.
If your current ecommerce platform is holding your business back — through poor performance, limited integrations, outdated architecture, or a catalog structure that no longer fits how you sell — we can help you plan a path forward. Next steps: 1. Share your ecommerce requirements and current pain points 2. Discuss your business model — B2B, B2C, enterprise, or marketplace 3. Review the integrations and functionality your platform needs 4. Define technical scope and architecture direction 5. Plan a development timeline and engagement structure
