There's a familiar pattern in IT procurement. Someone needs to connect two systems. They find a tool, available in a marketplace, easy to trial, inexpensive to get started. It seems to do the job. So they sign up, get it running, and move on.

Six months later, they're managing a consultant, paying invoices they didn't budget for, and fielding questions about why something broke over the weekend. Not to mention all the tricky questions their security team is asking them.

This is a common issue across an entire category of software. And it's worth understanding before you commit to it.

What synchronisation tools actually do

Synchronisation tools - for example Exalate - are designed to do one thing: move data between systems. Connect Jira to ServiceNow. Sync tickets from Zendesk to Azure DevOps. Keep a field mapping in place between two platforms so that teams working in different tools stay aligned.

For simple, contained use cases, they work. They’re quick to trial, low-cost to start, and available where IT teams are already looking - in marketplaces, on comparison sites, on a colleague’s recommendation. The pitch is usually the same: configure it yourself, no specialist required, up and running in days. There’s no problem with that. Yet.

The problem isn't what they do. It's what they can't do. And what happens when your environment outgrows them.

The cost you don't see on the pricing page

Synchronisation tools are typically cheap to license. A few hundred euros a month is common. That number looks good in a business case.

What doesn’t appear in that business case is the implementation cost. These tools are configurable, which is a nice feature until you realise that configuring them requires specialist knowledge your team probably doesn’t have in-house. That’s rarely made clear upfront. Most teams only discover it after they’ve committed. So you hire someone. A consultant, a partner, a specialist who knows the scripting engine well enough to make it do what you need.

Exalate, one of the more widely used tools in this category, typically comes with a consultant day rate of around €1,000 just to get it properly configured. And when something breaks - a platform update, a field mapping conflict, an edge case your scripts didn't account for - you need them again.

The total cost of a "low-cost" integration tool is rarely the number on the pricing page. It's the licence, plus implementation, plus ongoing maintenance, plus every incident that requires someone to come in and fix it.

What happens when complexity grows

Synchronisation tools are at their best when the use case is simple and stable. The challenges compound when environments evolve.

More systems are added. More custom requirements emerge. More business-critical processes depend on data flowing reliably, constantly. At that point, a deeper problem surfaces: these tools are built for developers and technical builders, not for the business stakeholders accountable for outcomes. 

The technical team keeps extending the tool, keeps requesting more resource. The business keeps asking where the results are. The gap between the two widens. Meanwhile, the scripting-based architecture becomes a liability - ‘secret coding’  no one knows how to use, more code to maintain, more points of failure, more things that silently break when one of your platforms pushes an update.

Organisations that have tried to scale on sync tools describe the same experience. What worked for one or two integrations starts deteriorating at five or ten. The tool that solved the first problem becomes the new problem.

And the response process is always the same. Find the consultant, explain the situation, wait for a diagnosis, wait for a fix, pay the invoice. There's no proactive monitoring built into the model. No one is watching your integrations on your behalf. 

The platform is available. So the outcomes are your responsibility.

The architecture question

Most synchronisation tools are built around a specific starting point, often a single platform like Jira or ServiceNow. They are then extended from there. The architecture reflects this, point-to-point connections from one system to another, configured from one side to work with the other.

That creates a constraint that becomes more visible as your environment grows. If the tool was designed for one platform, everything else is an adaptation. You're working against the grain of how it was built, and you feel it.

ONEiO takes a different approach. ONEiO sits as a translation layer. It adapts to how each platform wants to communicate independently, rather than forcing one to speak the language of the other. Our integration logic is transparent by design - visible, auditable, and built to be understood by the business, not just the developer who configured it. 

The result is an integration that’s genuinely system-agnostic, and one that doesn’t break when either side evolves.

The accountability gap

This is where the distinction matters most for IT leaders running complex environments.

Synchronisation tools are designed for developers and technical builders, not for the business leaders who are accountable for the outcomes. When you buy one, you’re getting access to a platform that your team (or the consultant you’ve hired) operates on your behalf. The technical team has something to configure. The business still doesn’t have a guaranteed result. If something goes wrong, you manage it. There’s no SLA on outcomes. Nobody on the other side of the contract is accountable for whether your integrations run reliably day-to-day.

ONEiO is a different proposition entirely. ONEiO owns the integration end-to-end. That means everything from implementation, monitoring, to maintenance and resolution. If something needs fixing, we fix it. If a platform update creates a conflict, we handle it before it reaches you. The outcome is guaranteed. Not just the platform uptime, but the actual delivery that you set out to achieve.

For organisations where integration failure has direct consequences (like SLA breaches, service disruption, missed commitments to clients), that accountability gap is not a minor consideration.

Data residency and compliance questions sync tools can't answer

For many organisations, integration isn't just an operational concern. It's a compliance one. Security policies, data protection regulations, and client contracts increasingly require knowing exactly where data flows, how it's handled, and where it's processed and stored. Sync tools like Exalate weren't built to answer these questions. 

There's no guarantee of data processing location, no clear audit trail for compliance teams, and no straightforward answer for the security team asking where customer data actually sits. 

For IT leaders in regulated industries, or those managing integrations that cross borders or organisational boundaries, that's not a fundamental liability. ONEiO gives you full control over where your data is processed and stored. It’s visible, auditable, and answerable to whoever is asking.

Quick comparison: Integration sync tools vs. managed integration services

Who should be paying attention

If you're running one or two simple integrations on a sync tool and they're working, this may not be your problem today.

But if you're starting to see the cracks at the edges - more complexity, more systems, more incidents, more consultant involvement than you expected - the question worth asking is whether the tool you chose for a simple use case is the right foundation for where your environment is heading.

Yes, the cost of switching is a consideration. But the cost of staying on a platform that can't support your environment at scale is usually higher, and harder to quantify until you're already in it.

Time to change?

Synchronisation tools are an attractive starting point. Low entry cost, quick to trial, available where IT teams are already shopping. For simple, defined use cases, they deliver.

The problems surface when complexity grows, when platforms change, when the integration environment needs to scale. At that point, the tool model breaks down — and the real cost of ownership becomes visible.

ONEiO is a different proposition: a fully managed service, with guaranteed outcomes, that scales with your environment rather than against it. It costs more upfront. It costs less overall.

If your integrations are mission-critical, predictability - of cost, of outcome, of what you’re actually buying - matters more than the number on the first invoice.
