Can small UK businesses benefit from Microsoft Power Apps? Yes, here's how SMEs are building custom apps without enterprise budgets, starting from £4,000.
Power Apps is not just for enterprise. Small and medium-sized UK businesses are using it to replace spreadsheets, automate approval processes, build customer portals, and create mobile apps for field teams, often for less than the annual cost of an off-the-shelf SaaS subscription they outgrew years ago.
Is Power Apps Right for Your Small Business?
Power Apps makes sense when:
- Your process is specific to your business and no off-the-shelf tool fits it without heavy customisation
- You are currently managing the process in Excel spreadsheets, paper forms, or email chains
- The process involves data entry, approvals, or information lookup that could be simplified with a structured interface
- You already have Microsoft 365, licences are partially or fully covered
- Multiple people need to access the same data simultaneously and accurately
- The process is recurring and high-volume enough to justify the build investment
Off-the-shelf is better when:
- Your process matches a standard software category well (accountancy, project management, HR) and you do not need significant customisation
- You have no Microsoft 365 subscription and would need to add it purely for Power Apps
- The process only involves one or two people and a shared spreadsheet genuinely works
- You need the app to be live in a matter of days with zero development budget
What Small Businesses Are Building with Power Apps
Job and project management apps Replacing paper job sheets and WhatsApp messages with a structured app where jobs are logged, assigned to technicians, tracked through stages, and closed off with photos and customer sign-off. Common in trades, field service, facilities management, and construction.
Expense and purchase approval apps Staff submit expenses or purchase requests via a simple mobile app. Managers approve via Teams notification. Finance sees a dashboard of all pending and approved spend.
Stock and inventory tracking apps Simple inventory management built on SharePoint or Dataverse, staff log stock movements on a phone or tablet, low stock alerts are sent automatically.
Customer service and complaint logging apps A structured intake form for customer contacts, linked to the customer record, with owner assignment and follow-up tracking.
HR absence and leave management apps Employees request leave via a mobile app. Line managers approve in one tap. HR sees a calendar view of all approved leave across the team.
Health and safety inspection and incident apps Digital replacement for paper inspection checklists and accident report forms. Mandatory fields ensure nothing is missed. Photos captured on the device.
Onboarding and induction tracking apps New starter checklist app for HR and line managers. IT equipment ordered, system access requested, induction sessions booked, policy documents acknowledged.
What Does It Cost for an SME?
| Tier | Cost Range | Description |
|---|---|---|
| Simple focused app | £4,000 – £7,000 | Single-purpose app replacing a paper form or spreadsheet. 5–8 screens, one data source (SharePoint), basic Power Automate notification. 4–6 week delivery. |
| Business app with approvals | £7,000 – £15,000 | Multi-function app with approval workflows, role-based views, and Dataverse data storage. 10–15 screens. 6–10 week delivery. |
| Connected business system | £15,000 – £30,000 | Multiple integrated apps sharing a Dataverse data model. External system integration. Power BI reporting. 12–20 week delivery. |
SME budget tip: Start small and prove value. A £5,000 app that solves your most painful operational problem is infinitely more valuable than a £25,000 platform that took 6 months to build and covers every scenario.
Do Small Businesses Need Microsoft 365 to Use Power Apps?
If you already have Microsoft 365 Business Basic, Standard, or Premium: You already have access to Power Apps, with standard connectors only. You can build canvas apps connected to SharePoint lists, Teams, OneDrive, Microsoft Forms, and Outlook without paying anything extra. The limitation: no Dataverse, no premium connectors.
Power Apps Premium Licence: ~£16.70 / user / month: Required for Dataverse, premium connectors, Power Pages external portals. For a small business with 15 app users, this is approximately £3,000 per year. Alternative: the Power Apps Per App Plan at ~£3.70 / user / month per specific app, 15 users × £3.70 × 12 months = £666 per year.
If you do not have Microsoft 365: You would need to subscribe to Microsoft 365 before using Power Apps. Microsoft 365 Business Basic starts at approximately £5 per user per month.
How Long Does It Take?
| Timeline | Phase | Description |
|---|---|---|
| Week 1 | Discovery | 2-3 hour workshop to document the current process, agree on scope, and identify data requirements. |
| Week 2 | Design | Wireframes and data model design presented for review. You approve the structure before any building begins. |
| Weeks 3–5 | Build | The app is built in two or three sprints with a review at each stage. |
| Week 6 | Testing and deployment | User acceptance testing with your team. Training session. Deployment to your Microsoft 365 tenant. |

DIY vs Professional Development
DIY works well for: Simple forms connected to SharePoint lists; basic data viewing apps; personal productivity tools for one or two people; prototyping and exploring ideas.
Professional development is worth it for: Apps used by more than 5 people; any app handling financial or HR data; apps with Power Automate flows; any app your business would be disrupted without; apps that need to look professional and branded.
The hybrid approach: Many SMEs find the best value in a hybrid approach: a professional partner builds the foundation (data model, security, core screens, Power Automate flows) and trains an internal maker to maintain and extend it.
