Why your DIY integration works: until it doesn’t
We’ve all seen it: a few well-crafted prompts, a bit of AI assistance, and suddenly you’ve got working code. The rise of ‘vibe coding’ — building software based on intent rather than deep technical expertise — is opening the door for more people to create their own tools and integrations.
At Xero, we’re leaning into this shift. It’s an incredible era for creativity, and we’re building tools like the Xero AI Toolkit to help all types of builders move faster than ever. But while the barrier to entry for coding has never been lower, the stakes for financial data have never been higher.
When that same approach is applied to financial workflows, the margin for error shrinks fast. What looks like a working integration on the surface can quickly unravel when it meets real-world accounting logic, compliance requirements, and scale.
We recently sat down with two of our seasoned Xero development partners: Andrew Sirianni from DCODE and Nathan Harper from AhoyAhoy. They are increasingly brought in after DIY builds hit their limits. Their message is simple: getting something to ‘work’ is one thing, but making it reliable, secure, and scalable is another entirely.
When vibes meet reality
The appeal of building your own integration is obvious. It’s fast, accessible, and often cheaper upfront. However, Andrew and Nathan are finding their teams being called in for ‘rescue’ projects to fix builds where the ‘vibe’ didn’t quite match the accounting logic.
“We see people picking up a lot of vibe coding that introduces major security flaws,” Nathan explains. “They’ll build something that works, then realise they’ve inadvertently exposed sensitive data to the public domain.”
Financial systems aren’t just about moving data from A to B. They rely on structured logic: tax rules, reconciliation processes, regional compliance, and edge cases that aren’t always obvious until something goes wrong.
Nathan sees the risks firsthand. “One of the biggest issues is security. We’ve seen builds where sensitive API keys are exposed or data isn’t handled safely. It might not be intentional, but it’s a real risk.”
What starts as a quick solution can turn into duplicated transactions, reporting inconsistencies, or worse: compromised financial data.
Three signs your integration has outgrown the ‘vibe’
While vibe coding is a great way to prototype, if your integration is showing any of the signs below, it is time to consider bringing in expert support.
- Your data isn’t as secure as you think
If your integration handles API keys, customer data, or financial records without robust security practices, you’re exposed. This includes things like hard-coded credentials, lack of encryption, or missing error handling. - It doesn’t understand accounting workflows
Moving data is easy. Mapping it correctly is not. If your integration isn’t accounting for tax rates, multi-currency transactions, or reconciliation logic, issues will surface: often at the worst possible time, like end of financial year (EOFY). - It breaks every time something changes
DIY integrations are often built once and left untouched. But APIs evolve, businesses grow, and requirements shift. Without ongoing maintenance, even a well-built script can quickly become unreliable or stop working entirely.
From quick fix to long-term solution
This is where the role of a development partner becomes critical. Unlike a one-off build, a development partner brings both technical expertise and a deep understanding of how Xero works in practice. They don’t just connect systems: they design integrations that hold up under real-world conditions.
“The goal isn’t just to make something work,” says Andrew. “It’s to make sure it continues to work as the business grows and changes.”
For businesses that have outgrown standard apps, this can be the difference between switching platforms entirely or building a solution that keeps everything running smoothly within Xero.
Finding the right fit: What to look for in a development partner
If you’re considering bringing in expert support, here are a few things to prioritise:
- Proven experience: Look for real-world examples of similar integrations or challenges solved.
- Regional expertise: Especially important for payroll, tax, and compliance requirements.
- Industry knowledge: Partners who understand your vertical can design far more effective solutions.
- Ongoing support: Integrations aren’t just ‘set and forget’ — long-term reliability matters.
Don’t let your business logic rest on a vibe alone. Connect with a partner who can turn that inspiration into a secure, scalable reality.
From idea to impact
Vibe coding has made it easier than ever for new builders to get started, and that’s a good thing. It’s unlocking creativity and helping more people build solutions tailored to their needs. But when it comes to financial data, reliability matters just as much as speed.
If your integration is moving beyond a simple prototype, working with a development partner can help turn a promising idea into something secure, scalable, and built to last.
