- Named work
- Atwix's Shopify Partner Directory profile features its role in Burpee's 2026 migration from Adobe Commerce to Shopify Plus, alongside the brand's internal team. ERP-heavy B2B work on Adobe Commerce includes Byrne Electrical's B2B portal with Epicor integration, built in 8 weeks (case page), with a 35% improvement in order accuracy reported on Atwix's Infor solution page; PowerPak, whose eCommerce grew 230% in the year after relaunch (client quote on the case page); and Turf Care, an Infor CSD client that has grown revenue roughly 70% in five years (case page).
- Engineering
- Sirius ERP Connector, its own middleware, built for Epicor Prophet 21, Infor, Kodaris and Expertek on Shopify, Adobe Commerce and Shopware 6; most deployments take 6-12 weeks (Sirius page). Its ERP page puts Shopify integrations at 2-4 weeks for NetSuite, 3-5 for Dynamics 365 and 4-6 for Infor CloudSuite, SAP Business One and Epicor.
- ERP and integrations
- Epicor P21, Infor, Kodaris, Expertek (Sirius); SAP Business One, Dynamics 365, Oracle ERP Cloud, NetSuite, Infor CloudSuite (ERP services page); ERP integration services at 6-12 weeks and $25K-$75K (B2B page).
- Best for
- Shopify builds and migrations where an ERP, pricing logic or the source platform is the hard part and the price must be settled before the build; teams leaving Magento, Adobe Commerce or Shopware who want a bench that knows the source data model (Adobe confirmed Atwix as the top contributing Magento partner in 2019; Atwix reports the top spot every year 2018-2025). Inc. 5000 #273 (2024) and #2327 (2025).
- Watch for
- built for stores with an ERP, B2B pricing or a legacy platform behind them; for a brand-led DTC launch with none of these, the DTC specialists in this directory (Anatta, Electric Eye) are a closer fit.
