Custom software or ready-made SaaS: which should you choose?

When a business decides it needs software, the first big question is: should we buy a ready-made tool (SaaS), or get software built just for us? Both can be the right answer. Here's how to decide.

What each option means

  • Ready-made SaaS: software already built for many businesses. You sign up, pay a monthly plan, and start using it. (New to SaaS? Read What is SaaS?)
  • Custom software: software designed and built for your business alone, around the way you already work. You usually own it.

Ready-made SaaS: pros and cons

Good: start today, low upfront cost, updates included, proven by many users.

Not so good: you adjust your process to the software; features you need may never come; monthly costs add up with many users; you don't own it.

Custom software: pros and cons

Good: fits your exact process, only the features you need, connects to your other tools, and can become an advantage your competitors don't have. You can even sell it to others later as your own SaaS.

Not so good: higher upfront cost, takes weeks or months to build, and needs a reliable development partner for support.

A quick way to decide

Choose ready-made SaaS if…Choose custom software if…
Your process is common (basic billing, email)Your process is unique to your business or trade
You need something this weekYou can plan a few weeks or months ahead
A good tool already does 90% of what you needEvery tool you tried misses something important
You have a small teamYou have many users, branches or partners
Software is not your advantageSoftware could become your advantage, or your product

The smart middle path

Many businesses do both: they use ready-made SaaS for common jobs (email, accounting) and build custom software only for the part that makes them special, like a dealer panel, a distributor network system or a customer app. Custom software can also connect your existing tools so data flows automatically.

Questions to ask any software partner

  1. Will I own the source code?
  2. Will I get a written quote with the scope and timeline?
  3. Can I see the screens before you start coding?
  4. How often will I see progress?
  5. What support do I get after launch, and what does it cost?
