E-Commerce Challenges We Solve

Rising customer expectations, tighter margins, and complex multi-channel operations are straining online retail teams

High Cart Abandonment

Confusing checkout flows, unexpected costs, and forced account creation drive shoppers away before they complete a purchase.

Slow Page Loads

Bloated storefronts and unoptimized media hurt conversion rates and search rankings alike.

Poor Mobile Experience

Clunky mobile layouts and slow mobile checkout leave revenue on the table as mobile share of traffic keeps growing.

Inventory & Order Sync Failures

Disconnected systems across storefronts, marketplaces, and warehouses lead to overselling and fulfillment errors.

Payment & Checkout Friction

Limited payment options and clunky gateway integrations add friction right at the moment of purchase.

Peak Traffic Scalability

Flash sales and events like Black Friday can crash under-provisioned storefronts at the worst possible moment.

Security and compliance

Security & Compliance Built In

E-commerce carries a higher bar for security than most other web applications – every checkout touches cardholder data and customer trust. We design payment handling, fraud prevention, and access control into the architecture from day one – then validate it with independent security testing.

  • PCI-DSS Compliance

    Tokenized payment processing and secure checkout flows mapped to PCI-DSS requirements for any site handling card data.

  • Fraud & Chargeback Prevention

    Fraud detection and chargeback protection built into the checkout and order-management flow.

  • DDoS & Bot-Attack Mitigation

    Traffic filtering and rate limiting to keep storefronts online during high-traffic sales events.

  • Penetration Testing

    Independent security testing of storefronts, checkout flows, and APIs, backed by our in-house pentesting team.

  • PCI-DSS
  • GDPR
  • CCPA
  • SOC 2
  • ISO 27001
  • OWASP Top 10

Accessible, Inclusive Shopping Experiences

As a WCAG and ADA compliance specialist, D2i Technology builds storefronts, product listings, and checkout flows to WCAG 2.1/2.2 AA from the ground up – then verifies them with manual assistive-technology testing, not just automated scans.

What we build in

  • WCAG 2.1 / 2.2 AA conformance
  • Accessible end-to-end checkout flows
  • Keyboard navigation for filters & search
  • Screen reader friendly product listings & alt text

Why Accessibility Matters in E-Commerce

  • Shoppers with visual, motor, auditory, or cognitive disabilities need to browse, compare, and complete purchases independently.
  • Retail and e-commerce is one of the most heavily litigated sectors for ADA web-accessibility demand letters and lawsuits in the US.
  • An inaccessible checkout is a lost sale - excluding any share of your audience from purchasing has a direct revenue impact.
  • Accessible design also improves usability for older shoppers and anyone on a low-bandwidth or assistive device.
