Running a small accounting practice in 2026 means competing with firms that have embraced AI. The good news: the technology is accessible, affordable, and genuinely transformative—even for practices with limited resources.
The challenge isn’t whether to adopt AI, but where to start. This guide cuts through the noise to help small practices implement AI that actually makes a difference.
The Small Practice AI Opportunity
Why Now Matters
Small practices have unique advantages:
Agility: You can implement changes quickly without committee approval
Direct impact: Time saved goes straight to your bottom line
Client relationships: Personal service enhanced by technology
Niche focus: AI tools can make specialisation more viable
The Reality Check
Be realistic about constraints:
Budget: You can’t buy everything
Time: Implementation takes effort
Skills: Learning curves exist
Clients: Some will adapt slowly
The key is starting smart, not starting big.

Starting with AI Assistants
The easiest entry point is AI assistants like ChatGPT and Claude. No software to install, no integrations to configure—just start using them.
Essential Use Cases
Client Communication
Before AI: 15 minutes drafting an email
With AI: 2 minutes to generate and polish
Example prompt:
“Draft a professional email to a client explaining why we need their bank statements by Friday to complete their year-end accounts. Tone should be friendly but firm.”
Technical Research
Before AI: 30 minutes searching IRS or HMRC guidance
With AI: 5 minutes for a synthesised answer (always verify)
Example prompts:
“Explain the current IRS rules for claiming home office deductions for self-employed individuals. Include the simplified method calculation.”
“Explain the UK rules for claiming home office expenses for self-employed individuals under the simplified expenses method.”
Template Creation
Before AI: Hours creating engagement letters, checklists
With AI: Minutes for first draft, then refine
Example prompt:
“Create a year-end accounts checklist for a small limited company, including documents needed and key deadlines.”
Choosing Between ChatGPT and Claude
ChatGPT strengths:
- Broader general knowledge
- Better integrations
- Code Interpreter for data analysis
- Larger user community
Claude strengths:
- Better with long documents
- More nuanced reasoning
- Cautious with uncertain information
- Excellent for complex analysis
Recommendation: Start with ChatGPT for general use. Add Claude when you need to analyse long documents or want more careful, detailed responses.
Cost-Effective Approach
- Start free: Both offer capable free tiers
- Upgrade one: Choose based on your most common use

Monthly cost: £16-20 for significant productivity gain.

Adding Document Processing
After AI assistants, document processing delivers the next biggest win.
The Case for Dext
Dext transforms document handling:
Without Dext:
- Client sends receipt image
- You open image, read details
- Type into accounting software
- File the image somewhere
- Time: 3-5 minutes per document
With Dext:
- Client sends to Dext
- Dext extracts and categorises
- You review and publish
- Time: 30 seconds per document
Implementation Steps
Week 1:
- Sign up for practice account
- Connect to accounting software
- Process your own receipts to learn
Week 2:
- Select 3 pilot clients
- Set up their inboxes
- Train them on submission
Week 3-4:
- Monitor and refine
- Create categorisation rules
- Expand to more clients
Calculating ROI
Simple maths:
- Documents per client per month: 30
- Time saving per document: 3 minutes
- Monthly time saved per client: 90 minutes
- Clients on Dext: 20
- Total monthly time saved: 30 hours
At £50/hour opportunity cost: £1,500/month value Dext cost for 20 clients: ~£200/month Net benefit: £1,300/month
Practice Management for Small Firms
Once basics are handled, consider practice management software.
Why Karbon Makes Sense
Karbon provides:
- Centralised task management
- Email integrated with workflows
- Client communication tracking
- Deadline management
- Team collaboration
The Small Practice Advantage
Larger firms struggle to implement practice management because:
- Too many existing processes to change
- Staff resistance at scale
- Complex approval requirements
Small practices can:
- Start from scratch with good habits
- Implement without committee approval
- Train everyone personally
Realistic Implementation
Month 1: Set up and configure Month 2: Use for one service line Month 3: Expand usage Month 4-6: Full adoption
Don’t try to do everything at once.

Avoiding Common Mistakes
Mistake 1: Trying Everything at Once
Problem: Overwhelm leads to abandonment
Solution: Implement one tool properly before adding another
Mistake 2: Skipping the Learning Curve
Problem: Tools underperform when not properly configured
Solution: Invest time in setup and training
Mistake 3: Not Measuring Results
Problem: Can’t justify continued investment
Solution: Track time saved and improvements
Mistake 4: Ignoring Client Readiness
Problem: Client pushback derails implementation
Solution: Start with receptive clients, demonstrate value
Mistake 5: Expecting Perfection
Problem: AI isn’t 100% accurate, leading to disappointment
Solution: Understand AI augments human judgement, doesn’t replace it
The Competitive Reality
Other practices are adopting AI. Those that don’t will:
- Spend more time on routine tasks
- Charge more for the same work (or earn less)
- Have less capacity for advisory
- Struggle to attract modern clients
The gap between AI-enabled and traditional practices will only widen.
