Should we build ourselves, use existing software or connect systems?
Building yourself gives control. Existing software gives speed. Smart integration can sometimes be just enough. The best route is the one that fits what you actually need, even if it's the least exciting one technically.
Does this sound familiar?
This question often arises when the first search turns up dozens of AI tools, but not a single solution fits the process exactly.
Many possible tools already exist
It's hard to judge which differences matter and which are mostly marketing.
No product fits completely
Standard software covers a large part, but misses a few important pieces.
Custom software sounds attractive and expensive
You want to know what control or flexibility the extra investment really delivers.
Integrations can be a middle ground
Maybe one system doesn't have to do everything if existing parts can be connected well.
Where do you want to be?
You don't want to choose a platform you later have to build around, nor fund custom software for something that already exists and works fine.
A reasoned build-buy-integrate choice
You know which parts can be standard and where custom work really adds value.
Understand dependencies up front
Lock-in, integrations, data and extensibility are part of the choice.
A practical technical route
You know where to start and which investments may come later.
Why does this happen?
Build versus buy is rarely a binary choice. Many good solutions deliberately combine standard software, APIs and custom work.
See how we approach thisComparing features is not enough
Data ownership, permissions, integrations and future changes often matter more than the feature list.
Lock-in only becomes visible later
A quick start can become expensive when important data or workflows are hard to move.
Custom work is too quickly seen as all-or-nothing
Sometimes only the distinguishing part needs to be built yourself.
AI Reality Check
The AI Reality Check compares the relevant technical routes and makes clear what you'd better buy, connect or build yourself. If you then mainly want to develop software yourself, a Vibe Code Kickstart can lay the foundation. For larger custom implementation, Build & Integrate can follow.

Why 9to5 for this?
Because 9to5 both builds software and integrates existing systems, we don't automatically reason towards one type of solution.
View casesCustom work is not a goal in itself
We only build ourselves where that offers enough advantage.
Integrations are a fully-fledged route
Good existing software doesn't need to be thrown away.
Future freedom counts
The cheapest start isn't always the best technical choice in the longer term.
What else fits your situation?
Vibe Code Kickstart · €4,950 excl. VAT
We set up the technical foundation properly. After that, you or your team keep building independently with Claude Code, Codex, Cursor, Lovable, Bolt or other AI coding tools.
View offerBuild & Integrate · Fixed price after scoping
You know what needs to be built. We build it professionally, connect it to your existing software and make sure it can be handed over production-ready.
View offerDo we need AI for our idea?
You have a problem or product idea and suspect AI could be a solution, but first want to know whether that is technically and practically the wisest route.
