Power Apps
Power Apps is Microsoft's low-code platform for building custom internal business applications. Trellist designs and builds Power Apps for IT and operations leaders who need a specific internal tool that off-the-shelf software doesn't cover, without a full custom development project.
Let’s TalkWhat we do
- Custom App Design & Development
- Data Integration
- Workflow Automation
- User Experience Design
- Ongoing Support
Internal tools built around your specific workflow, not adapted from a generic template that almost fits.
Connecting apps to SharePoint, Dataverse, or other systems, so the app works with data that's already accurate.
Pairing apps with Power Automate for end-to-end processes, not just a form that still requires manual follow-up.
Internal tools designed to actually be used, not just technically functional.
Maintenance and iteration as needs evolve, so the app doesn't become outdated the year after launch.

Our Approach
We start by identifying the workflow and requirements for the app. From there we architect the app's data model and user experience, develop and test inside your Microsoft 365 environment, and maintain and iterate post-launch.
Signs You Need This
- A specific workflow still runs on a spreadsheet passed around by email.
- You've looked at off-the-shelf software, but nothing quite fits how the process actually works.
- A full custom development project feels like overkill for the problem you're trying to solve.
- IT doesn't have bandwidth to build and maintain a bespoke internal tool from scratch.
What You’ll Gain
- A workflow finally out of spreadsheets and email chains, into a real tool.
- Faster turnaround than a full custom development project would require.
- An internal tool people actually want to open, not one they tolerate.
- Ongoing support so the app evolves instead of becoming outdated within a year.
How It Compares
Trellist builds on the Microsoft 365 platform you already license, with attention to actual usability. That's different from full custom software development, which costs more and takes longer for a problem this scoped, and different from forcing the workflow into a generic off-the-shelf tool that never quite fits.
Frequently Asked Questions
What kinds of processes are a good fit for Power Apps?
Processes currently living in spreadsheets, email chains, or paper forms — anywhere manual coordination creates errors or delay.
Do we need a Microsoft 365 upgrade for this?
In most cases, no — Power Apps capability is included in most standard Microsoft 365 business and enterprise plans.
Can a Power App handle a fairly complex process?
Often yes — the platform scales further than most teams expect, though we'll tell you honestly if a use case needs full custom development instead.
How long does a typical Power App take to build?
A well-scoped app is often a matter of weeks, not months — that's part of the appeal versus a full custom build.
Why Trellist
We build on the platform you already license, so there's no new software to learn or pay for.
