Software

Custom software or
off-the-shelf software?

Buy when a product fits. Build when your process is the point, or when the cost of working around a product keeps growing. This guide gives you the questions, the cost comparison and a week-long way to decide.

The honest default

If a good product fits your process closely, buy it. Off-the-shelf software is cheaper to start, proven by other users and supported by someone else. Custom software earns its place in specific situations, and they are easy to recognise.

The deciding questions

Which way each question points
QuestionPoints to off-the-shelfPoints to custom
Does a product fit most of the process unchanged?YesNo, you would bend the process to fit
Is the process a source of advantage?No, it is standardYes, it is how you win work
How many tools are stitched together by hand?One or twoSeveral, with copy and paste between them
How quickly must it be live?SoonYou can phase delivery
Will licence costs grow with headcount?SlowlySteeply
Do you need to own and export the data freely?Standard exports are enoughOwnership and portability are critical
Are there audit or compliance needs?The product covers themYou need controls specific to you

Compare the cost over three to five years

The first invoice is a poor guide. Compare the full cost of each option over the period you expect to use it.

  • Licences, including per-user growth and add-ons.
  • Staff time spent on workarounds and manual steps.
  • Integration upkeep between tools.
  • Customisation limits and the price of getting around them.
  • For custom: build, hosting, maintenance and support.
  • The cost of changing course later.

The middle path

It is rarely all or nothing. A common, sensible pattern is to keep a proven product for the standard work and build only the layer that makes you different: an integration, a customer portal, a dashboard or an approval flow. You keep the maturity of the product and add the fit you are missing.

Signs you have outgrown off-the-shelf

  • Your team keeps a spreadsheet beside the system to do what it cannot.
  • Data is typed into more than one place.
  • You pay for features you never use and lack the one you need.
  • Each change request ends with “the software cannot do that”.

Red flags on either path

  • No way to export your data in a usable form.
  • Only one person understands how it works.
  • No documentation, tests or handover plan (for custom).
  • A roadmap that depends entirely on the vendor’s priorities (for off-the-shelf).

How to decide in a week

  1. Map the process as it runs today, including the workarounds.
  2. List the must-haves and the nice-to-haves.
  3. Trial two suitable products against the must-haves.
  4. Ask for a rough scope for a custom build.
  5. Compare the three-year cost of each option.
  6. Decide, and write down why, so you can revisit it honestly.
