Custom software can transform how a business runs - fewer spreadsheets, faster decisions, happier customers and staff. But many projects fall short: they run late, cost more effort than expected, or launch and quietly go unused.
In our experience across 1,500+ projects, the cause is rarely the technology. It is almost always a handful of planning, communication and ownership mistakes made early on. The good news is that each one is preventable. Here are the twelve we see most often, and what to do instead.
The mistakes at a glance
| Mistake | Early warning sign | Prevention |
|---|---|---|
| Unclear goals | Nobody can say how success will be measured | Write one measurable outcome for the project |
| No product owner | Decisions take weeks or contradict each other | Appoint one decision maker with authority |
| Skipping discovery | Estimates vary wildly between vendors | Fund a short discovery and requirements phase |
| Building everything at once | Huge feature list, distant launch date | Phase the project, start with a focused first release |
| Ignoring end users | Only managers are consulted | Involve daily users from day one |
| Underestimating data migration | "We will just import the Excel" | Plan, clean and test migration early |
| Uncontrolled scope creep | Many "small" changes by phone or WhatsApp | Written backlog and change process |
| Weak testing | Bugs found by customers after launch | Acceptance criteria and user testing |
| Ignoring non-functional needs | Slow pages, no backups, security as an afterthought | Define performance, security and backup needs upfront |
| Choosing on the lowest quote alone | Vague proposal, unclear team | Compare scope, team, process and ownership |
| No ownership terms | Code lives in the vendor's private account | Contract for code, data and credential handover |
| No adoption or support plan | Staff keep using the old method | Training, champions and a post-launch support plan |
Let us look at each in more detail.
1. Starting without a clear goal
"We need an app" or "we need an ERP" is not a goal. Without a clear outcome, every feature request seems equally important.
Instead: write one sentence that defines success - for example, "Dispatch should be able to see every approved order in one place, so that no order waits more than a day for dispatch planning." Every feature should support that outcome.
2. No single product owner
When the founder, the operations head and the accounts team all give instructions, developers receive conflicting priorities and decisions stall.
Instead: appoint one product owner on your side who gathers input from others, makes decisions and is available to the development team regularly.
3. Skipping discovery to "save time"
Jumping straight to development without analysing processes, users and rules almost always costs more time later, when misunderstandings appear in working software.
Instead: invest in a short discovery phase - process mapping, user interviews and a written requirements document - before committing to the full build.
4. Trying to build everything in version one
Large, all-at-once projects take longer to deliver value, are harder to estimate and carry more risk.
Instead: break the project into phases. Start with the workflow that causes the most pain, launch it, learn and then expand.
5. Designing without the people who will use it
Managers know what reports they want, but the people entering data every day know where the real friction is.
Instead: involve end users in interviews, wireframe reviews and testing. Software that suits daily users gets used; software they find awkward gets bypassed.
6. Underestimating data migration
Old data is messy - duplicate customers, inconsistent product names, missing fields, years of history in different formats. Leaving migration to the last week is a classic cause of delayed launches.
Instead: inventory your data early, decide what must move, clean it before migration and run trial imports well before go-live.
7. Letting scope creep in through the side door
"Can you just add one more field?" said on a call is how projects slowly double in size. Each change seems small; together they move the launch date.
Instead: keep a written backlog. Every new idea is recorded, estimated and prioritised. You decide consciously whether it joins this phase or the next.
8. Treating testing as the developer's job alone
Developers test that code works. Only the business can confirm that it works the way the business needs.
Instead: agree acceptance criteria for each feature and schedule user acceptance testing with real scenarios - including returns, cancellations, partial payments and other edge cases.
9. Ignoring non-functional requirements
Speed, security, backups, access control and audit trails are invisible until something goes wrong.
Instead: define them upfront: how many users, which devices, what uptime expectations, how often backups run, who can see what. If the software handles personal data, plan for consent, access control and secure storage in line with the Digital Personal Data Protection Act, 2023. A sound hosting and deployment setup - our cloud and DevOps team handles this - matters as much as the code.
10. Choosing a partner on the lowest quote alone
Quotes vary because scope interpretations vary. The lowest quote may simply include less - fewer tests, no documentation, no support.
Instead: compare proposals on scope clarity, team composition, process, communication, testing approach, ownership terms and support. Ask who exactly will work on your project and whether they are in-house.
11. Not securing ownership of code and data
Some businesses discover too late that their source code sits in a vendor's private account, or that they have no access to the server.
Instead: make sure your contract states that, on payment, you own the source code and data and receive repository access, server and third-party credentials, and documentation. Ideally, the code repository is in your organisation's account from the start.
12. Launching without an adoption and support plan
Launch day is the beginning, not the end. Without training and support, staff drift back to spreadsheets and WhatsApp.
Instead: plan training sessions, nominate internal champions, run the old and new processes side by side briefly if needed, and agree a support and enhancement arrangement for the months after launch.
What good communication looks like
Many of the mistakes above come down to communication. A healthy project usually has:
- A regular rhythm - for example a weekly call and a demo at the end of every development cycle, so progress is visible in working software, not only in status reports.
- One shared place for decisions - a project tool or shared document where requirements, decisions and change requests are written down, rather than scattered across phone calls and WhatsApp chats.
- Honest early warnings - a partner who tells you about risks and delays as soon as they appear, with options, rather than at the deadline.
- Clear points of contact - a project manager on the vendor side and a product owner on yours, each with a backup.
If you are not seeing working software at regular intervals, ask why. It is the single most reliable signal of a project's real progress.
A simple project health check
Ask these questions at any stage of a project:
- Can everyone state the project goal in one sentence?
- Is there one named decision maker on each side?
- Is there a written, prioritised backlog?
- Do we see working software at regular demos?
- Have real users tested the latest version?
- Is data migration planned and trial-tested?
- Do we have repository access and current credentials?
- Is there an agreed plan for training and post-launch support?
If you answer "no" to more than a couple, it is worth pausing to fix the process before writing more code.
If you need extra hands
Sometimes the issue is capacity rather than process - your internal team is stretched or lacks a particular skill. In that case, adding experienced developers to your team through a hire developers arrangement can be more effective than starting over with a new vendor.
Key takeaways
- Most software project failures are caused by planning and ownership gaps, not technology.
- Start with a measurable goal, one product owner and a proper discovery phase.
- Phase the work, involve end users and manage change through a written backlog.
- Plan data migration, testing and non-functional requirements from the beginning.
- Secure code and data ownership in the contract, and plan adoption after launch.
