Power Platform consultancy, run by one management accountant.
Castlane is a Power Platform consultancy for businesses of five to fifty people that run on spreadsheets. Power Apps for the screens, Power Automate for the chasing, Power BI for the numbers, all in the Microsoft 365 you already pay for, and all built by the same person who did the finance job first.

What I build with it
Power Apps
The application your team works in: one record per job, client or candidate, with permissions and a history. An office app on the desktop and, where people are out on site, a phone app that writes to the same data.
Power Automate
The work that happens without a screen: certificate chasing, approvals, the morning unbilled summary, the pay run file. Built with a failure path on every flow so nothing breaks quietly.
Excel systems
Not Power Platform at all, and sometimes the right answer anyway. A costing model or reporting pack that one person owns is often better as a properly built workbook: no licences, no logins, from £900.
The rest of the platform, in plain words
- Dataverse is the database underneath. It holds the records, enforces who can see what, and keeps the history. Every application I build with more than one user sits on it.
- Power BI is the reporting: margin by job, by client and by engineer, from the same data the office enters, refreshed on a schedule. It is where a management accountant earns the fee.
- Power Pages is a website your clients or suppliers log into. I have built a billing-enabled client portal on it for a London tuition group; it is quoted as part of an application build when a business needs one.
- SharePoint holds the documents and, for simple single-list apps, the data. It is the no-extra-licence option where the process is small enough.
Dynamics 365 and Copilot Studio are not what Castlane sells. If your business needs them, I will say so on the call and point you to someone who does.
Why a small consultancy rather than a large one
A larger Power Platform partner is the right choice for a two-hundred-seat rollout with a change programme behind it. For a business of five to fifty people with one or two processes that have outgrown a spreadsheet, that structure is the cost: a sales call, a solution architect, a developer you never meet, and a day rate that turns an £8,000 problem into a £40,000 project.
At Castlane the person on the call maps the process, builds the system and trains the team, at a fixed price agreed before the build starts. The trade-off is scale: I take on a few builds at a time, and I say no to the ones that need a bigger team.
