Why Custom Instead of Off-the-Shelf?
Generic software forces you to adapt your operations to the tool. Custom software adapts to you. The upfront cost is higher, but you eliminate monthly SaaS fees, workarounds, and ceiling limitations.

- No recurring platform fees after launch
- Scales with your business without tier limits
- Full data ownership and portability

Common Questions
How much does custom web application development cost?
Custom web apps at 47 Industries start at $5,000 for simple tools. Most business applications with user accounts, databases, and a dashboard run $10,000 to $30,000. Complex platforms with multiple integrations and roles start at $30,000+.
What is the difference between a website and a web application?
A website displays information. A web application lets users log in, manage data, and take actions. Examples: a restaurant website is a website; a reservation system where restaurants manage tables and customers book online is a web application.
How long does it take to build a web application?
Simple apps take 6 to 10 weeks. Business apps with multiple roles and integrations take 12 to 20 weeks. Complex platforms take 6+ months. We give you a timeline before any work starts.
Can you build a web app that connects to existing software?
Yes. We build integrations with QuickBooks, Stripe, HubSpot, Google Calendar, Zapier, Twilio, and any service with a public API. Third-party integrations are quoted as part of scope.
Do we own the code when the project is done?
Yes. Full source code ownership at project completion. No licensing, no hosting lock-in, no ongoing fees unless you choose a maintenance contract.
