Custom software and AI development, scoped and priced before code
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. Best fit for SoftDoes, with results from client reviews: Operations teams replacing manual work: an educational support company cut time spent on administrative work by 30% and internal follow-up emails by 35%, and a real estate agency cut time spent on manual administrative tasks by 35%. AI automation: an education company cut student-teacher matching from 15 minutes to under 5. Enterprise and public sector: a $200,000+ reporting platform for a government agency with more than 10,000 employees cut reporting time by 30%. Customer-facing apps: a marketing company's new mobile app raised engagement by 34% and 90-day retention by 22%. "[SoftDoes] built our full AI-powered SaaS platform from scratch. 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. A paid discovery and estimate costs $490 and is credited toward the build. Hourly development starts at $50, AI automation projects at $2,500, MVPs at $8,000, dedicated developers at $4,000 per month and support plans at $500 per month. Clients own 100% of their code, accounts and IP from day one.
