Custom Business Software Is Getting Quicker and Cheaper

Most businesses keep a quiet list of projects that never quite happened:

• The stock system that would have ended the spreadsheet juggling

• The customer portal everyone agreed was a good idea

• The reporting tool that would have saved the finance team two days a month

None of them were bad ideas. They were simply too slow or too costly to build, so they lost out to whatever else was competing for the budget that year.

In 2026, that maths is starting to change.

What has actually changed

A new generation of AI-assisted development is steadily making custom business software quicker and cheaper to build. Claris, the company behind the platform we have built on for more than two decades, describes a shift where work that once took weeks can be done in an afternoon, and projects once dismissed as too costly to pursue become worth building again. For a business owner, that is the direction of travel. Over time, the system you parked because it would have taken three months and a sizable invoice could become a far smaller undertaking.

Speed is the headline, trust is the real story

Faster is only useful if what you end up with can be trusted to run your business. This is where a lot of the current AI excitement quietly falls down. As Claris chief executive Ryan McCann points out, an app built by AI still needs everything a proper system needs: a database, user permissions, audit logging, backup and recovery, and infrastructure your business controls. Which raises the question every owner should ask:

Where does it actually run, and how is it kept secure and managed?

A clever tool knocked together in an afternoon is not the same thing as a business system. The difference is everything that surrounds it, namely where your data lives, who can see it, and whether it will still be working this time next year.

The answer is to build on a proper foundation rather than a loose collection of parts. Claris FileMaker brings data, logic, interface and security together in one platform, so anything built on it inherits those protections from the start. Speed without that footing is a liability. Speed with it is a genuine advantage.

You are not the only one thinking this way

This is not a fringe idea. Gartner expects that by 2026, eighty per cent of the people using low-code tools will sit outside the IT department, up from sixty per cent in 2021. In other words, decisions about software are increasingly being made by the people who run the business, not only the technical team. The appetite for bespoke business systems is clearly there. What separates a good outcome from a frustrating one is having the right partner to shape it.

Built to keep running, even on a difficult day

The Claris FileMaker 2026 release, now available, leans into exactly the things that matter to an owner: resilience, business continuity and staying power. It strengthens how a system keeps a safe copy of your data and how quickly it can recover if there is a problem.

In plain terms, less risk of downtime and a quicker route back when something does go wrong. Peace of mind, built in. We will take a proper look at what the 2026 release brings in a dedicated post soon.

Time to dust off the wish list

If you have a process still held together by spreadsheets, workarounds, or software that almost fits, this is the moment to look at it again. At iSOS we have spent more than twenty years building bespoke business software on Claris FileMaker, and the 2026 release is gradually widening what is realistic for budgets that previously would not stretch. Have a look at the kind of systems we build, then get in touch and tell us what you shelved. We will tell you honestly whether it is worth a second look.

Frequently asked questions

Is custom business software worth it for a small business?

In many cases, yes. If your team is propping up daily operations with spreadsheets, manual rekeying or several disconnected apps, a single bespoke system usually pays for itself in saved time and fewer mistakes. The calculation is shifting in 2026, because AI-assisted development is gradually bringing the cost of building down, so projects that did not stack up a year ago are increasingly worth a fresh look.

How long does it take to build custom business software?

Less time than it used to, and that gap is widening. AI-assisted development is steadily compressing work that once took weeks, and over time a focused first version of a system can increasingly be in your team's hands within days rather than months. The exact timescale depends on how complex your processes are.

How much does custom business software cost compared with off-the-shelf software?

Off-the-shelf tools look cheaper at first, but the monthly licences, unused features and manual workarounds add up. A custom system is built around exactly how you work, and with faster modern build methods the upfront cost is far more accessible than it used to be. We are always happy to give you an honest view of the numbers for your situation.

Is software built with AI secure and reliable enough to run a business?

It can be, as long as it is built on the right foundation. A tool generated in isolation still needs a proper database, controlled access and dependable backups. Building on an established platform like Claris FileMaker means your system inherits that security, and the Claris FileMaker 2026 release strengthens business continuity further with new resilience and recovery capabilities.
