JWilliams & Associates

JWilliams & Associates is a US-based custom software and AI development company serving businesses since 2005. We build enterprise applications, SaaS platforms, AI agents, and workflow automation that solve operational problems and turn business ideas into working software.

Our services include custom application development, API development and systems integration, SQL Server engineering, data migration and ETL, and legacy application modernization. We connect ERP, WMS, and CRM systems—including Epicor Prophet 21 and HighJump—to reduce manual work, automate processes, and make business data more useful.

We also design, own, and operate our own software platforms. That experience shapes how we approach client projects, from UI/UX and architecture through deployment and ongoing support. Our engineering team is US-based, with no offshore outsourcing.

Clients deserve clear expectations and visibility into the work they are funding. We offer fixed-price projects with defined scope, deliverables, milestones, and payment terms agreed upfront. Throughout development, our Command Center gives clients visibility into project progress, keeping them informed and involved as we build.

For selected projects, an MVP or product demonstration lets clients evaluate the interface, workflow, and core functionality before committing to a complete build. In-house financing and flexible payment plans are available for qualified projects, subject to approval.

Whether you need a focused integration, a modernized application, or a new software product, we start with your goals, existing systems, and operational requirements—and build around them.
