Toca and Power Platform
Outgrown Power Platform? Run it on Toca.
Toca was built for the work Power Platform finds hardest: complex, regulated processes at high volume. Around 276,000 workflows run on it every day, for NHS trusts and the UK's busiest law firms. Your Microsoft 365 stays where it is, and the two work together.
Why teams move to Toca
For the app that has become hard to change, hard to run and hard to budget.
A number of law firms have come to us after building complex apps in Power Apps and Power Automate. They had run into the same three things.
- When the app gets complex
A simple app is quick to build. Every rule, screen and connection added after that makes the next change harder, and the effort of keeping it running compounds. On Toca the whole process lives in one workflow, whether a step is an API call, an RPA bot or code, and Git is built into every workspace, so a change can be branched, committed and rolled back.
- When the volume climbs
An unattended desktop bot in Power Automate runs one flow at a time, so more work at once means more bots, each under its own licence. Around 276,000 workflows run on Toca every day, in production, and we think much of that work would be close to impossible to run reliably on Power Platform.
- When the bill follows headcount
Standard connectors come with Microsoft 365, but a premium connector, a custom connector or the on-premises data gateway means every person who uses that app needs a premium licence. Toca is priced per workflow, not per seat, so the cost follows the work and you know it in advance.
Side by side
The same work on each, row by row.
Microsoft's side is taken from Microsoft's own documentation and its UK price list.
- Code when you need it
Power PlatformServer-side code is a Dataverse plug-in in C# on .NET Framework, run in a sandbox with a two-minute limit.
TocaActions and connectors in C# on .NET Core, app components in React, analytics in Python, with full NuGet, from a browser IDE. What you write becomes a drag-and-drop block in the same workflow and audit trail, and the IP is yours.
- Change control
Power PlatformSolutions and pipelines move work between environments, with Git through Azure DevOps.
TocaToca 10 builds Git into every workspace, so you can branch, commit and roll back.
- Systems with no API
Power PlatformDesktop flows run on Windows machines you register, or on Windows 365 machines Microsoft hosts, with each unattended bot under its own Process licence.
TocaRPA bots run anywhere and are managed centrally, in the same workflow as API calls and C# connectors, under a service account you control. Agent bots inside your network connect outbound to Toca, needing only internet access and an entry on your allow-list.
- Cost
Power PlatformPer user and per bot. Power Apps Premium is £15.40 per user per month, Power Automate Premium £11.50 per user per month, and each unattended desktop bot £115.30 a month, paid yearly and before VAT.
TocaPer workflow, not per seat. Typically £1 per referral in NHS acute and general hospitals, with no other costs, and £30,000 to £150,000 a year as a guide for law firms, depending on workflows, users and apps.
- AI on decisions that matter
Power PlatformMicrosoft says Copilot Studio is not intended as a medical device, and leaves clinical use to whoever builds with it. Some generative AI features can process UK data outside the UK once an administrator allows it.
TocaSpectral is UKCA-marked as a Class I medical device. More than one model reads every document, a person settles every disagreement, and the models can run entirely inside your boundary.
- Clinical and regulated work
Power PlatformBuild a clinical app yourself, in Power Apps or anything else, and your organisation is its manufacturer, carrying the clinical safety case.
TocaFor eTriage and Spectral, Toca is the manufacturer and keeps the safety case with a named Clinical Safety Officer, under ISO 42001, ISO 27001 and Cyber Essentials Plus.
- Where it runs
Power PlatformMicrosoft's cloud, in the region you choose, the UK included. Systems on your own network are reached through the on-premises data gateway.
TocaOur cloud, your own tenancy, or your own servers, air-gapped if the data can't leave the building. You choose for each deployment.
Microsoft's side is from Microsoft's own documentation, checked on 10 November 2026, and its UK pricing pages, read on 11 November 2026. Microsoft changes its licensing often; if anything here has moved, tell us at sales@toca.io and we'll put it right. Microsoft, Microsoft 365, Power Platform, Power Apps, Power Automate, Copilot Studio, Dataverse, Teams and Windows 365 are trademarks of the Microsoft group of companies.
Who runs on Toca
In production, not in a pilot.
NHS trusts and the UK's busiest law firms run on Toca today.
We needed to reduce our case handling duration so that we could process more claims.
How they work together
People stay in Teams and Outlook. The hard work runs on Toca.
Nothing needs ripping out. Keep Power Platform for the everyday team apps it does well: an approval in Teams, a form on a SharePoint list, a flow that tidies an inbox. Toca connects to the Microsoft estate you already run, and the two can hand work to each other.
- Microsoft 365 and Teams
Toca's Microsoft 365, Teams and Azure connectors read the mailbox, post to Teams and file to SharePoint, so a process can start and finish where people already work.
- One sign-in
Toca apps sign in through Microsoft Entra ID, so people use the account they already have, under the access policies you already set.
- From a Power Automate flow
Toca listens for webhooks, so a flow can start a Toca workflow with a single HTTP call and pick up the result. Microsoft licenses the HTTP action as premium.
- From a Copilot agent
Copilot Studio agents can use Toca workflows as tools over MCP, so an agent can ask Toca to act, under Toca's audit trail, with a person signing off wherever it matters.
