Look at your credit card statement. How many software subscriptions are on it? Some you use every day. Some you forgot you had. And some you use every day while your team still does the real work by hand, because the tool doesn't quite fit how your business runs.

Now AI tools are piling on. So which do you need: a ready-made AI tool you rent by the month, or an AI assistant built for your business?

Here's the short answer. Buy a ready-made tool when it already fits most of your process. A custom build makes sense when three things are true. The job is costly to do by hand. The steps are specific to your business. And the ready-made tools still leave your team doing the real work. Below is a simple way to decide, with real published prices for custom work.

Your three options

The AI builder SuperDupr describes three honest options. Here they are in plain English.

  1. Build it yourself with a no-code tool. No-code means you set it up by clicking and filling in forms instead of writing software. It can work for one simple task if someone on your team enjoys this kind of work.
  2. Rent a ready-made tool. You pay a monthly fee for software someone else built and keeps running. It's best when the product already fits most of how you work.
  3. Have it custom built. A builder makes an AI assistant that works inside your tools and follows your rules. It's best when nothing ready-made fits, or when you want to own the system instead of renting it.

When a ready-made tool makes sense

  • The tool already does most of what you need, the way you need it.
  • It connects to the software you already use, without extra work.
  • Your process is common, like booking appointments for a single location.
  • The task is small, or you're still figuring out how you want it done.

SuperDupr's advice is direct: "Do not pay for a custom build of a solved problem." Naurra.ai, another builder, says a ready-made tool is "usually" cheaper to start. Its list of reasons not to build custom includes this one: "Off-the-shelf tools already cover 90% of the need."

When a custom build makes sense

  • The job eats a lot of hours or money when your team does it by hand.
  • Your steps are specific to your business, so ready-made tools don't fit.
  • The ready-made tool still leaves your people copying, checking and re-entering.
  • It has to work inside your own systems and follow your own rules.
  • You want the system, the accounts and the data to belong to your business.

Naurra.ai describes the same three signs: "the manual workflow is expensive, the process is specific to your business, and the SaaS still leaves your team doing the real work by hand." (SaaS means software you rent by the month.)

A simple way to decide between renting a tool and a custom build.

Two examples

What custom work costs

These are three builders' own published prices, which I cover in detail in what a custom AI build costs:

  • For a small, focused build, their published ranges run from $3,000 to $20,000.
  • Monthly running costs in their lists range from $50 to $500 (Aayush Jain) up to $200 to $2,000 for SuperDupr's support plan.

One more point from Aayush Jain: connecting to your other software is usually the most expensive part of a custom build. He notes that if a ready-made tool already connects to your systems, "you skip the most expensive line item." That's one more reason to check the ready-made tools first.

Five questions to decide

  1. Is there a ready-made tool that does most of this job today?
  2. Does it connect to the software I already use?
  3. With that tool, would my team still do the real work by hand?
  4. How many hours a week does this job take, and what do those hours cost me?
  5. Do I need to own the system, the accounts and the data?

If questions 1 and 2 get a yes and question 3 gets a no, rent the tool. If not, a custom build is worth a quote.

Send me your answers to those five questions with your request, and I'll send you a custom quote. No sales calls.
