What We Build

Comprehensive Custom E-Commerce Engineering

01

Modular Microservices Architecture

Building lightweight microservices (Catalog, Cart, Inventory, Checkout) that run independently, ensuring platform updates can be pushed without downtime.

02

Transactional Database Architecture

Designing relational databases (PostgreSQL) optimized for ACID-compliant purchase ledger records, preventing transaction collisions.

03

Multi-Warehouse Inventory Sync

Engineering inventory systems to track stock allocations across multiple physical stores, warehouses, and suppliers in real-time.

04

Bespoke Checkout & Cart Engines

Building checkout pipelines that calculate dynamic shipping fee models, coupon combinations, and local tax requirements.

05

API-First Headless Storefronts

Decoupling frontends (using React, Next.js, or mobile clients) from backend databases, connecting via fast GraphQL API gateways.

06

Enterprise ERP & Accounting Sync

Connecting custom engines to existing ERPs (SAP, NetSuite), warehouse systems, and accounting platforms via secure adapters.

The Challenge

When your business model outgrows Shopify, you need proprietary engineering.

SaaS commerce tools (like Shopify) are powerful, but they enforce limits: strict catalog sizes, rigid checkout layouts, high per-transaction fee structures, and limited multi-warehouse inventory configurations. For businesses with complex logistics, multi-entity tax structures, or proprietary subscription rules, modifying standard platforms becomes a costly engineering workaround. Worse, you are locked into their ecosystem, paying escalating licensing and app subscription costs. Quecko builds custom e-commerce platforms from the ground up. We map your specific logistics, order routing, and catalog rules to architect a unified, secure database and codebase that you own entirely.

FAQ

Frequently Asked Questions

A custom platform offers complete freedom. You pay no monthly subscription fees or transaction commissions, have total control over checkout layouts and catalog attributes, and can build custom inventory workflows that Shopify does not natively support.

We use PostgreSQL or similar enterprise relational databases that enforce strict transactional boundaries. If a transaction fails mid-checkout, the database rolls back the database state to prevent corrupt orders or data loss.

Yes. We build custom API connectors and secure middleware to sync inventory stock quantities, shipping statuses, and customer profiles with external enterprise tools (SAP, NetSuite).

Timelines typically range from 4 to 6 months based on the complexity of catalog structures, ordering logic, and integrations. We deliver modular features using a phased launch strategy.
