Legacy software replacement

Legacy software replacement, with software made to fit.

Growing businesses collect software. Each tool made sense once; together they cost more than they return. Isomorph Labs replaces legacy software and overlapping subscriptions with systems built for how your business works, then cancels what they replace.

01Retire, replace, keep

Every system in scope gets one of three decisions. The decision is written down with its reason before anything is cancelled.

  • Retire

    Platforms whose price has outgrown their use, tools that need a specialist to operate and services kept only because switching felt harder than staying.

  • Replace

    Purpose-built software that does exactly what the business needs, owned by you and running on infrastructure you control.

  • Keep

    Systems that already earn their place stay. Replacing working software for its own sake is a cost, and we avoid it.

02When legacy software replacement pays

Any one of these is a reason to look. The best time to start is about ninety days before the next renewal, so the replacement runs before the contract rolls over.

  • Renewals that rise faster than the value received
  • Specialists needed to run routine tasks
  • Data copied by hand between tools
  • Features paid for and never used
  • Workarounds that have become the process
  • Vendors that slow every change you request

FAQQuestions

Plain answers to the questions we hear most.

What does legacy software replacement involve?
It involves mapping what each system actually does for the business, building replacements for the parts that matter and cancelling the rest. Data is migrated and checked before any contract ends.
Is custom software more expensive than a subscription?
Not over its life when it replaces several subscriptions. The proposal states the build cost and the recurring cost it removes, so the payback period is known before work starts.
What happens to our data?
It moves to systems you own. Migration is checked record by record against the source before the old system is switched off.
Which systems do you replace most often?
Back-office platforms, reporting tools and niche industry software with high per-seat pricing. Core systems that work well are usually kept.
