If you have never commissioned custom software before, the process can feel opaque. You know you need something built, but you are not sure what the journey looks like from initial conversation to launch.
Understanding the process reduces anxiety, sets realistic expectations, and helps you be a better partner to your development team. In this article, we walk through each phase of a typical custom software project so you know exactly what to expect.
Phase 1: Discovery (1-2 Weeks)
Every well-run project starts with discovery. This is where the development team learns about your business, your current processes, your pain points, and your goals. The output is a shared understanding of what needs to be built and why.
During discovery, expect a series of conversations — sometimes with different stakeholders in your organization. The development team will ask questions you might not have considered: Who are all the users of this system? What happens when something goes wrong in the current process? What data do you need to report on?
At the end of discovery, you should receive a scope document or proposal that describes the system in plain language, outlines the features, estimates the cost and timeline, and identifies any risks or dependencies. This document is your contract — make sure you understand and agree with everything in it.
Phase 2: Design (1-3 Weeks)
With the scope defined, the team designs the user interface and system architecture. You will typically see wireframes — simplified layouts that show the structure and flow of each screen without visual design details.
This phase is your best opportunity to catch misunderstandings before any code is written. Review wireframes carefully. Walk through the key workflows mentally: If I am a user logging in to submit a request, does this flow make sense? Are all the fields I need here? Is anything missing?
Changes during design are inexpensive. Changes during development are costly. Invest your attention here.
Phase 3: Development (4-12 Weeks)
This is the build phase, and it is typically the longest. A good development team works in sprints — short cycles of one to two weeks where they build a set of features, test them, and show you the progress.
Expect regular demos or updates. You should be seeing working software, not just status reports. At each demo, provide feedback. Does this match what you expected? Is anything confusing? Did you think of any new requirements?
Be responsive during this phase. Development teams frequently need decisions from you — clarifications on business rules, approval on design choices, or input on edge cases. The faster you respond, the faster the project moves.
Phase 4: Testing (1-3 Weeks)
Before launch, the software goes through structured testing. The development team tests for bugs, performance issues, security vulnerabilities, and edge cases. But they also need you to test.
User acceptance testing (UAT) is where you and your team use the software the way you would in real life. You are not looking for code bugs — you are verifying that the system supports your actual business processes. Test the happy paths (everything goes right) and the unhappy paths (what happens when data is missing, a step is skipped, or an error occurs).
Document any issues you find and prioritize them. Not every issue needs to be fixed before launch — some can be addressed in a post-launch update. Your development team will help you triage.
Phase 5: Launch and Handoff (1 Week)
Launch day is when the software goes live. Depending on the system, this might be a big-bang launch (everyone switches at once) or a phased rollout (starting with a small group and expanding gradually).
Your development team should provide training for your staff, documentation for common tasks, and a clear support process for reporting issues after launch. They should also monitor the system closely during the first few days to catch any problems quickly.
Expect a few bumps. No matter how thorough the testing, real-world usage always surfaces issues that were not anticipated. A good development team treats these as expected follow-ups, not failures.
Phase 6: Ongoing Support
Software is a living product. After launch, you will need ongoing maintenance: security updates, bug fixes, performance monitoring, and eventually new features as your business evolves.
Clarify the support arrangement before the project starts. What is included? What costs extra? What is the response time for critical issues? Having this defined upfront prevents misunderstandings later.
