You have a feeling something isn’t right with your company’s software. Things take longer than they should, changes cost an arm and a leg, and when you ask the technical team, the answer doesn’t quite convince you.
The problem is you don’t know how to program. So you have no way to check whether that feeling has any grounding.
The good news: you don’t need to know how to code to audit software. You need to know which signals to look for. A good technical auditor doesn’t start by reading code: they start with the business, the processes and the money. The code comes later.
This guide explains how to run a first review yourself, which signals should put you on alert, and when it’s worth asking for an external second opinion.
Why audit your software even when “it works”
Software that works is not the same as software that is well built. Many systems hold on for years working badly, eating up money and opportunities without anyone noticing.
The most common invisible costs:
- Lost team hours on manual tasks the software should be automating.
- Expensive changes. Every new feature costs more than the one before because the system is tangled up.
- Dependence on one person. Only one developer (or one agency) understands the code, and that leaves you negotiating from weakness.
- Lost customers. A slow website or an app that crashes drives users away without a complaint ever reaching you.
Auditing isn’t about finding culprits. It’s about knowing the real state of what you have, before a problem forces you to find out.
Step 1: what you can check yourself (without touching code)
Before hiring anyone, you can run a first inspection with the eyes of the business. These are the signals that matter.
Red flags: your software probably has a problem
| Signal | What it means |
|---|---|
| Nobody wants to touch it. The technical team avoids changes or delays them. | High technical debt: the code is fragile and developers are afraid of breaking it. |
| Every change costs more and takes longer than the one before. | The system is accumulating poorly managed complexity. |
| Only one person or agency understands it. | You’re in vendor lock-in. They raise prices, and you wait. |
| Frequent crashes or errors, especially at key moments. | Stability or scalability problems. |
| There is no documentation, or what there is is years old. | If that person leaves, the knowledge leaves with them. |
| The system has no tested backups. | Serious risk. If something happens, you lose everything. |
If you recognise two or more of these signals, you don’t need to know how to program to know there’s a problem.
What you should be able to ask your team
Even if you’re not technical, you can (and should) ask these questions:
- When was the last time something important was updated without breaking anything?
- What would happen if the person who maintains the system stopped showing up tomorrow?
- Do we have backups, and have they ever actually been restored (not just verified that they exist)?
- How much does adding a new feature cost today compared to a year ago?
- Is there documentation someone new could understand within a week?
The answers tell you more about the health of the system than any technical metric.
Step 2: when you need an external second opinion
The first review tells you whether there’s a problem. To know what to do about it, you usually need an outside look.
Why it should be external
The team that built the system, however professional it may be, is not impartial. They have legitimate interests: defending their work, justifying past decisions, selling more hours. It’s not malice, it’s incentives.
An external audit brings three things your team can’t give you:
- Impartiality. No stake in the verdict being “it’s fine” or “it has to be rebuilt”.
- Comparative perspective. Someone who has seen dozens of systems knows what’s normal and what isn’t.
- Business judgment. It’s not about whether the code is pretty, but whether the technology serves the business or holds it back.
What to ask of a serious technical audit
An audit worth what it costs must hand you, at a minimum:
- A clear diagnosis, in language you understand, of the real state of the system.
- A risk classification: what’s urgent, what’s important and what’s cosmetic.
- A prioritised action plan: what to do first, what can be left for later, what each thing costs.
- An opinion on the current team/provider (are they reliable, do you need reinforcement, or is it time to change?).
- A cost estimate for the recommended actions, so you can decide with a clear head.
If an audit doesn’t deliver this, you paid for hot air.
Step 3: how to choose who audits you
This also calls for care. These are the signs of a good auditor:
- They ask about your business before your code. If they start talking about technology without understanding your model, they’re not what you need.
- They deliver bad news if there is any. An auditor who only finds small problems to avoid awkwardness is no use to you.
- They don’t sell their own execution as the only option. If the only solution on the table is hiring them to rebuild everything, be suspicious.
- They talk in euros and timelines, not just technical jargon.
- They explain the why behind every recommendation, so you can defend it internally.
What an audit is NOT
To avoid confusion:
- It’s not a deep security review (that’s a pentest or a cybersecurity audit, a different thing).
- It’s not a development roadmap (that comes later, once the audit is done).
- It’s not a quick 15-minute opinion based on a quick glance. A serious audit takes days of analysis.
What to do after the audit
Once you have the diagnosis and the plan, the most important thing is not to rush. Typical mistakes:
- Wanting to rebuild everything from scratch. It’s almost never necessary, and it usually goes badly.
- Doing nothing because the plan scares you. Cheap ends up expensive.
- Handing the decision to the same team that created the problem.
The reasonable path: prioritise what’s urgent, plan what’s important, and decide with a cool head what to do about everything that doesn’t hurt so much.
Conclusion
You don’t need to know how to program to know whether your software is costing you money. You need to know which signals to look for, ask the right questions and, when the time comes, get a second opinion that has no stake in selling you anything.
