SaaS Sprawl: tackling finance’s biggest challenge head-on

When was the last time you audited your finance team’s tool stack? Over the years, you’ve probably tried out different software for expense management, invoicing, and budgeting. There’s never been so much technology available as there is now, and it’s only normal that your tech stack grew organically, but that, at some point, you lost track of it. This is what is coming to be known as SaaS Sprawl.

Each tool acquisition seemed reasonable in isolation, but what happens when the sum of those parts doesn’t equal a whole that makes sense? You can end up with slower processes and disconnected data because the tools intended to fix a problem ended up creating new ones.

Keeping your tool stack from becoming a problem, or reverting it if it already is, is part of a your role, and it means building frameworks to help you decide what to keep, what to cut, and how to redesign your stack to best meet your team’s needs. Whether you’re being proactive or reactive about it, this article serves as a practical guide for finance leaders looking to improve their tool stack processes.

The tools that were supposed to fix everything

Over the past decade, the finance software market has been growing at a steady pace. For almost every finance pain point, from expense management to procurement, there is now a dedicated tool. Far from having already peaked, the market is projected to reach US$16.3 billion by 2030, according to a report by Research and Markets.

Finance tools promise automation and speed, a key selling point for finance teams. The problem starts when tool acquisition goes unchecked, enter SaaS sprawl, which can undermine that initial promise.

There is such a thing as too much of a good thing, and software is no exception. Nintex reports that 41% of businesses add new tools to their stack every one to three weeks, and 51% of mid-market organisations report having between 100 and 300 tools in their tech stack. Another report by Productiv shows that 48% of enterprise applications are unmanaged, with no one assigned to monitor or audit their use.

The tools themselves aren’t the problem, but rather a lack of strategy for their adoption. Without a clear overview of existing processes and software architecture, your tech stack can lead to duplicated tools, workflow delays, and even security risks.

The hidden cost of a fragmented stack

For each tool added to your stack, there’s an associated cost that chips away at your budget. 

87% of businesses surveyed by Nintex report that SaaS sprawl has a moderate-to-major financial impact on their organisations. However, the real impact is on operations and team efficiency.

If your tool stack isn’t optimised to your team’s processes, they end up having to switch between systems, manually exporting data to bridge tools that aren’t connected, and spending time on training every time you adopt new software. While individual tools may help automate and speed up certain tasks, if each of those tools doesn’t work well together, you end up with a fragmented and inefficient stack.

This can further lead to shadow processes. When your tool stack becomes too difficult to manage, for example, if one of the tools isn’t straightforward to use, people end up finding workarounds. Instead of not only not fixing the problem it was meant to solve, this tool also created a side process that not everyone is following because, most of the time, it isn’t documented or officially approved by a manager.

When integrations become the bottleneck

Shadow processes can also originate from tools that don't work well together. Most finance stacks rely on integrations to function. To exchange data between tools, you need APIs, middleware, or manual exports. If just one tool updates its API or changes its data structure, these connection points fail, leading to broken processes, more manual work, slower reporting, and even stalled projects.

This is what we call the integration tax, which most teams are unaware of but are still paying. And there’s a compounding risk to it as well. The more tools in the stack, the more integrations there are, increasing the likelihood that the whole system will break. 

What was meant to be automated ends up creating friction and more tasks for those using the software.

Data quality and the single source of truth problem

SaaS sprawl, shadow processes, and the integration stack aren’t the only issues a tool stack can create. A fragmented stack can also generate fragmented data. If the tools don’t sync in real time, or, worst-case scenario, at all, the same metric may exist in multiple platforms with slightly different values. These discrepancies lead to finance teams that lose confidence in their own data.

Being a finance leader today means you need to have both technical and soft skills. One of them is breaking data silos between teams through listening and observation. But they also have to do it inside their own teams.

Finance teams facing this kind of data problem need leadership to decide where the single source of truth lies. This means understanding exactly where data lives, who owns it, and which platform takes precedence when the numbers don’t match.

How to audit and rationalise your finance tech stack

If this has resonated with how your team has been working so far, what you need to do is audit your current tech stack. 

1) Start by mapping out your stack. 

List every tool and what it’s used for, its integrations and licence cost, and which team/employee and process(es) it serves. Simply by taking this first step, you’ll often notice redundancies, for example, two different tools for the same task.

Most finance leaders have never systematically done this audit, but once you have the initial map, it’s easier to keep the process going. The next step is deciding which tools to keep and which to cancel. 

2) For each tool, ask yourself and your team three diagnostic questions:

• Does this tool solve a problem that couldn't be handled by something we already use?
• Would removing it require a workaround, or would the process actually improve?
• Is it used consistently across the team, or only by a subset of people?

Your role is about more than approving tools. You should also take a strategic approach to the technology used, asking questions such as: “What capabilities do we need that our current setup doesn’t handle?” or “What are we keeping out of habit rather than necessity?”

The goal is not about cutting tools for its own sake or simply to save on licence costs. Auditing and rationalising your finance tech stack ensures that every tool in your stack has its place, in terms of cost and operational purpose, and works along with the rest of your stack. Tools like Spendflo, which centralise SaaS purchases, renewals, and compliance, can help finance teams keep their tech stack under control so it doesn’t become a problem again.

Preventing SaaS Sprawl: fewer tools, better outcomes

In the future, you’ll probably remember the last time you audited your tech stack, because it shouldn’t be a one-off exercise. Your team’s needs might change, and the finance software market doesn’t stop. At any time, there might be a new tool that’s more cost-effective or tackles a roadblock you didn’t know you had.

The modern CFO’s role includes keeping up with market evolution and understanding which changes to make and when to make them. And remember: more tools don’t mean more capability. Finance teams who’ve made deliberate decisions about which tools (not) to use are often those who keep a competitive advantage.
