Edvantis provides front-end development, UI/UX design, Makeswift visual editing setup and performance optimization for strong Core Web Vitals.

BigCommerce Integrations and Custom Apps

Use BigCommerce’s APIs to connect your store with ERP, PIM, OMS, CRM, BI and payment systems. We build secure, event-driven integrations and custom apps.

B2B Ecommerce Development

Give business buyers the self-service experience they expect. We set up and extend BigCommerce B2B capabilities, including company accounts, buyer roles, custom price lists, quotes, purchase orders and invoice portals. We also integrate them with your ERP so wholesale and direct-to-consumer (DTC) sales run on one platform.

AI and Agentic Commerce

AI agents now search, compare and buy on customers’ behalf, and they rely on accurate product data to do it. We help you enrich and structure your catalog and product feeds so AI channels can find and recommend your products. We also build AI shopping assistants, personalized recommendations and generative AI content workflows.

Ecommerce Analytics

Understand how customers find, compare and buy your products, including through AI-driven channels. We combine data from your store, marketing, ERP and other channels into a single source of truth. On top of it, we deliver self-service dashboards, demand forecasting and customer lifetime value (LTV) and churn models your teams can act on.

Ecommerce Testing and Security

Protect revenue and customer trust. We provide automated functional, performance and checkout testing, plus penetration and API security testing.

How Edvantis Helped Modernize a Global Ecommerce Platform

After integrating a new application into their portfolio through an acquisition, our client, a well-known global SaaS e-commerce platform, was looking for an experienced software development team to enhance their solution. In this next phase of product development, they aimed to bring in experts to modernize legacy software, implement new features, and maintain core platform components.

After a meticulous selection process, Edvantis was chosen as the partner for this initiative. Over the past four years, our Dedicated Team of 30 to 50 Software Developers and QA Engineers has played a crucial role, contributing to the success of multiple client projects, from modernizing legacy software to deploying new ecommerce features.

Together we:

Performed code updates and migration of the company’s core product components to a modern tech stack
Implemented end-to-end back-office internalization and localization to Chinese, Ukrainian and French languages
Developed a new application that allowed the client to replace third-party products with native app features
Integrated third-party payments, enhancing the e-commerce platform's capabilities for a broader range of transactions

With the help of Edvantis Engineers, the client managed to deploy new robust ecommerce features and attract a new cohort of international sellers to their platform.
