Is custom software cheaper than five SaaS subscriptions?

Often, yes, once the subscriptions, the duplicate data entry and the hidden admin hours are all counted, not always, but more often than the headline subscription prices suggest.

What does SaaS sprawl actually cost a business?

Beyond the subscriptions themselves, fragmented systems commonly cost a typical £3–8m UK business £125,000 to £400,000 a year, mostly through margin loss, wasted labour and cash-flow friction.

When does SaaS still make more sense than bespoke software?

When a business's needs are genuinely generic, small team, standard processes, an off-the-shelf tool is usually the right call.

Is custom software cheaper than buying five SaaS products?

Q: When does bespoke software cost less than SaaS?

Once a business is running more than three or four separate tools with regular duplicate data entry between them, one bespoke system usually costs less over three years than the sprawl it replaces.

By Euan Pallister

Often, yes — once you count the subscriptions you're already paying for, the ones you'll need next, and the hours lost re-entering the same data into each. Five disconnected SaaS tools can cost more than one bespoke system, even before fragmentation is counted as a cost in its own right.

What does a typical SaaS stack actually cost?

Add up the subscriptions most £3–20m businesses accumulate over a few years of growth — a CRM, an invoicing or job-management tool, a reporting or BI add-on, a couple of smaller point tools for specific teams — and the combined monthly total is rarely small, even before you count what those tools fail to do for each other. Each one is justified on its own. Together, they rarely add up to one coherent picture of the business.

What does SaaS sprawl cost beyond the subscriptions?

We've put a number on this elsewhere on this site: finance directors we've spoken to put the cost of fragmented systems at well into six figures a year for a typical £3–8m business — a realistic range of £125,000 to £400,000 — mostly through margin loss, wasted labour and cash-flow friction, not through any one dramatic failure. See what we can claim, and what we borrow for where that figure comes from. That's the subscriptions' hidden running cost: the admin hours spent re-entering the same order in two systems, the report someone rebuilds by hand every month because none of the tools talk to each other.

When does bespoke software cost less than SaaS?

Once the number of separate tools climbs past three or four, and once duplicate data entry becomes a daily habit rather than an occasional annoyance, one system that actually reflects how your business runs usually costs less over three years than the sprawl it replaces — not because the software itself is cheaper, but because the labour it saves is real money, not a rounding error.

When does SaaS still make more sense?

When your needs are genuinely generic — a small team, standard processes, nothing distinctive about how you operate — an off-the-shelf tool is usually the right call, and we'd say so if you asked us. Bespoke software earns its cost when your business does something specific enough that a generic tool keeps getting in the way of it, not before.

How do you actually compare the two?

Guessing at the comparison is how most businesses end up either overpaying for software they don't need or underpaying for years of hidden labour. The honest way to compare is to put real numbers against both paths — your actual subscription spend and admin hours, against the real cost of a bespoke build.
