SoftDoes is a Kansas City custom software and AI development company, founded in 2019, that builds custom software, web platforms, mobile apps, MVPs and AI automation for startups, growing businesses and enterprise teams in the United States. One SoftDoes team handles discovery, UX and UI design, development, testing, launch and ongoing support. What SoftDoes builds: Custom software: internal operations platforms that replace spreadsheets, customer and patient portals, SaaS products and integrations, built with React, Node.js, Python and .NET on AWS and Azure. AI development: AI agents, chatbots, document extraction and workflow automation on OpenAI and Anthropic Claude models, added to the systems a business already uses. Web and e-commerce: custom web applications, business websites and online stores, including Shopify. Mobile apps: iOS and Android apps for customers and field teams.

They were communicative and reliable, consistently delivering quality work on schedule." (Upwork client review, AI-powered SaaS platform for construction) How SoftDoes prices work: every project starts with a written scope and price before any code is written.
