Sandcastle Web Design and Development

Sandcastle Web Design & Development is a Seattle web design and development agency founded in 2001. For more than two decades we have built, migrated, and maintained ecommerce stores and custom web applications for manufacturers, distributors, and specialty retailers across the United States.

We are a nopCommerce Partner and a Shopify Partner, and we also work in AbleCommerce, WooCommerce, BigCommerce, WordPress, and Umbraco. Our specialties include:

• Ecommerce development and replatforming, with migrations in any direction across Shopify, BigCommerce, WooCommerce, and nopCommerce
• cXML and OCI punchout catalog integration (Level 1 and Level 2) connecting supplier stores to procurement systems such as SAP Ariba, Oracle Supplier Network, Coupa, and Jaggaer, including cXML invoicing
• ERP data exchange between ecommerce sites and systems such as Salesforce, NetSuite, Epicor Prophet 21, and Microsoft Great Plains
• Custom application development on the Microsoft stack (ASP.NET, C#, SQL Server) and Azure
• WordPress design, development, and monthly care plans covering plugin and core updates, off-site backups, uptime monitoring, and malware cleanup

We keep the team small on purpose. Clients work directly with the developers who build and maintain their sites, and every project gets a senior developer, not a hand-off chain.
