Next Olive builds eCommerce apps and marketplaces that convert: fast catalogs, frictionless checkout, real-time inventory and AI-driven recommendations.

What we deliver

  • Custom storefronts and multi-vendor marketplaces
  • Headless commerce on Shopify, Magento or custom backends

Why Next Olive

  • Checkout flows tuned for conversion
  • Scales for sale-day traffic spikes
  • Integrations with ERP, POS and logistics partners
  • Growth features: loyalty, referrals, push campaigns

From single store to marketplace

We have built D2C brand apps, B2B ordering portals with tiered pricing and credit limits, and multi-vendor marketplaces with vendor onboarding, commission rules and payouts. The right architecture depends on your catalogue size, vendors and margins — we help you choose before writing code.

Performance is a feature

Slow product pages cost sales. We optimise image delivery, cache catalog data, pre-compute search indexes and load-test checkout so your app stays fast during campaigns.

AI that sells more

Add visual search, smart recommendations, dynamic bundles and an AI shopping assistant that answers product questions from your own catalogue data.

Our delivery process

  1. Discovery: We map goals, users, integrations, and success metrics in a focused workshop.
  2. Architecture: Solution design, milestone plan, and transparent estimate with clear assumptions.
  3. Design: UX flows and prototypes validate the experience before full build.
  4. Agile delivery: Two-week sprints with staging demos and visible backlog progress.
  5. QA & launch: Testing, UAT, production deployment, documentation, and optional SLA support.
