Systems
Does the flow stay inside Microsoft 365, or span line-of-business systems?
Resource / Comparison
Power Automate or custom? It depends on the flow.
Power Automate is often the right first choice for simple flows in Microsoft 365. Custom automation pays off when the flow spans many systems, needs AI judgment, or must run with full control. Here is the honest comparison.

- 01
What Power Automate is best at
Notifications, approvals, simple flows between Outlook, Teams, SharePoint, and Excel, and connections to hundreds of standard services - without writing code. For a business already living in Microsoft 365, the threshold is low and early wins come fast.
- 02
Where standard tooling stops
Complex branching, advanced error handling, AI assessment of documents and images, tight logging and versioning, or flows across line-of-business systems without good connectors. Click-built flows then grow fragile, costly to change, and hard to debug.

How Aprex assesses this - also against ourselves
We do not build Power Automate solutions. Recommending the tool anyway when it fits loses us an assignment but keeps trust. Send your flow and we will honestly say whether it belongs in Power Automate, in custom code - or in a combination.
- 04
The combination most end up with
In practice: Power Automate for notifications and simple connections, custom services where AI, heavy integrations, or strict operations are required. The point is never the tool - it is that the flow gets faster, safer, and measurable.

FAQ
- Is Power Automate enough for our business?
- Often yes, for simple Microsoft 365 flows. Send a flow example to post@aprex.no - we will honestly say so even when the answer is that you do not need us.
- What does custom automation cost versus Power Automate?
- Licenses versus development hours - but total price is set by change needs and operations over time. A fragile click-flow needing constant fixes soon costs more than code.
- Can Power Automate combine with own code?
- Yes, and it is often the best solution: standard flows where they hold, own API services where AI, logging, or complex integrations are required.
- Does Aprex build Power Automate solutions?
- No, we build custom. But we openly recommend Power Automate when it fits the case - ask us for an honest assessment.
Honest against ourselves too
This page recommends a Microsoft product we do not sell, where it fits. The reason is simple: advice you can trust brings customers you can keep.
