Why Today's Business Tools Are Better – But One Big Challenge Remains

In the past, businesses often relied on all-in-one systems: big, heavy platforms designed to handle everything in one place. They got the job done, but they came with a major downside. If you wanted to change or improve one part of the system, you had to overhaul the whole thing. Imagine trying to replace just one module in an ERP system — nearly impossible without disrupting everything else.

Today, businesses are moving towards specialised, flexible apps that work together seamlessly. It is a shift from monolithic platforms to a modular toolkit, and it changes how a business chooses, runs and grows its software.

What was wrong with the old all-in-one platforms?

All-in-one platforms promised simplicity: one system, one login, one provider for everything. In practice, that convenience came at a cost. Because every part was tightly bound to every other part, a small change rarely stayed small. Upgrading one function meant testing and reworking the whole system, so many businesses simply left things as they were.

That rigidity also meant paying for features you never used, and being tied to a single provider's pace and priorities. When the platform fell behind, so did you.

Why are specialised, modular apps better?

Modular apps take the opposite approach. Instead of one system that does everything, you assemble a set of specialised tools that each do one job well and connect to the others. This approach comes with real benefits:

• Pick what works for you. Specialised tools let you choose exactly what you need for each job, without paying for extra features you will never use.
• Switch easily. If one app no longer works for you, you can replace just that app without touching the rest of your setup. It is like swapping out a single tool in your toolkit instead of buying a whole new set.
• Less risk, less stress. You can roll out changes step by step, so it is easier to adapt without disrupting your entire workflow.
• Get the best of the best. You are not locked into one provider. You can mix and match apps from different providers to create a setup that works perfectly for you.
• Grow as you go. Add new tools or features as your business evolves, without having to start over.

Choosing the right tool for each job matters more in this model, because each tool is a deliberate decision rather than something bundled in by default. Even a familiar workhorse like a spreadsheet deserves the same scrutiny — it is worth asking whether Excel is the right tool for the task in front of you, or whether a specialised app would serve you better.

How do all-in-one platforms and modular apps compare?

The contrast is easiest to see side by side:

Consideration	All-in-one platforms	Specialised, modular apps
Changing one part	Overhaul the whole system	Replace a single app
What you pay for	Features you may never use	Only what you need
Risk when you change	High — disrupts everything	Lower — roll out step by step
Provider choice	Locked to one provider	Mix and match the best
Growing your setup	Start over to scale	Add tools as you go

Each row points the same way: modular setups give you more control over cost, risk and pace than a single bundled platform can.

What is the one big challenge that remains?

For all their flexibility, modular setups still leave one hurdle in place: data migration.

Switching tools often means moving your data — files, records and attachments — from one system to another, and this process is rarely straightforward. Formats differ, attachments go missing, and the mapping between old and new systems is seldom clean.

Why is data migration so difficult?

Some of the difficulty is technical, but not all of it. To make matters worse, some platforms intentionally create "stickiness" for commercial reasons, designing systems that make migration even harder. These barriers can leave businesses feeling trapped, even when they know better solutions are available.

The result is a quiet form of lock-in. A business may have outgrown a tool, found a better one, and still stay put simply because moving the data feels too painful or too risky.

How can businesses avoid getting stuck?

The way out is to treat data portability as a feature, not an afterthought. Favour tools that make it easy to export and move your data, adopt changes gradually rather than all at once, and avoid depending on a single provider for everything. Where data does need to move between systems, techniques for reshaping and connecting data — such as those used to streamline consolidation with Power Query — can take some of the pain out of the process.

The takeaway

Modern systems are giving businesses more flexibility, but data migration remains a key hurdle to unlocking their full potential. Staying stuck should not be the answer — businesses deserve tools that work for them, not against them. For teams thinking about how their tools and skills will need to change, it is part of a wider conversation about the role of accountants and their future as work becomes more modular and more automated.

So, what do you think? Are today's tools helping businesses work smarter, or is the migration challenge still holding us back?
