Turning an Excel File into an App: What 4 Weeks Actually Look Like
When we say "your app in four weeks, fixed price," we sometimes get a polite smile. That's fair, we've all seen projects drag on. So let's pull back the curtain.
Week 1: we scope
We sit down with you, we understand your process, we sketch the screens together. Above all, we lock the scope. This is the most important step: a clear scope guarantees the timeline and the price.
Week 2: we build the foundation
Database and first screens. By the end of the week, you see something real, not a diagram. We adjust quickly, while it's still easy to change.
Week 3: we add the intelligence
Business logic, automations, connections to your tools. The app goes from "pretty mockup" to "tool that does the work."
Week 4: we test with you, and we ship
Your users take the app for a spin, we gather their feedback, we adjust, we move to production. At the end, an app that runs, not a prototype.
What throws a short project off the rails (and how to avoid it)
Just one thing, almost always: scope that swells along the way. "While we're at it, we could also...". Each little addition seems harmless, but stacked together they blow up the timeline. Our method: we note these ideas in a "version 2" list, we celebrate them, and we ship the working version 1 first. Then we improve, on solid ground.
Key takeaways
- Four weeks: scoping, foundation, intelligence, testing and go-live.
- The number-one risk is scope that swells. We park it in "version 2."
- The fixed price commits both sides: locked price, guaranteed timeline.
- Lock in the testers' availability from the start.
