ReAI vs Crunch

Crunch is a UK accounting platform that combines software with access to qualified accountants, targeting freelancers, contractors and small limited companies. ReAI is an AI-powered accounting platform built for UK small businesses with a focus on automation and self-service. Both serve the UK market, but they take fundamentally different approaches.

Here is how they compare.

Quick Comparison

Pricing

Crunch Plans

Crunch’s pricing includes accountant services baked into the monthly fee. You are paying for both software and people.

ReAI Pricing

ReAI starts at £22/month with all features included: invoicing, bank feeds, automated categorisation, VAT filing and reporting. Pricing scales with transaction volume rather than business structure.

Cost Comparison

For a sole trader, Crunch costs £34.50-£49.50/month versus ReAI at £22/month. The difference is £12.50-£27.50 per month (£150-£330 per year).

For a limited company, the gap widens significantly. Crunch’s limited company plan starts at £84.50/month (£1,014/year), while ReAI remains at £22/month (£264/year). However, Crunch’s price includes accountant-prepared annual accounts and Corporation Tax returns, which a ReAI user would need to handle separately or engage an external accountant.

The Accountant Question

This is the core difference between the two platforms.

Crunch

Crunch gives you access to qualified accountants as part of the subscription. Depending on your plan, this includes:

• Accountant review of your bookkeeping
• Preparation and filing of annual accounts
• Corporation Tax return preparation and filing
• Self Assessment filing
• Tax advice by phone and email
• Year-end review

For business owners who want someone else to handle compliance, Crunch removes the need to find and manage a separate accountant.

ReAI

ReAI focuses on making the software smart enough that day-to-day bookkeeping requires minimal human intervention. AI categorises transactions, matches payments to invoices, and prepares VAT returns. The business owner (or their external accountant) retains control of the process.

For businesses that already have an accountant or are comfortable managing their own bookkeeping, ReAI provides the tools without the bundled human cost.

Which Approach Suits You?

Automation and AI

ReAI

ReAI’s AI engine learns from your corrections and progressively automates more of the bookkeeping:

• Transaction categorisation – AI categorises bank transactions, improving accuracy over time
• Invoice matching – AI matches payments to outstanding invoices
• Anomaly detection – flags unusual transactions for review
• VAT coding – automatic VAT treatment based on transaction patterns

Crunch

Crunch uses basic automation (bank rules and manual categorisation) supplemented by human accountant review. The software handles data capture, but the intelligence comes from the Crunch team reviewing your records periodically.

For businesses that process high transaction volumes, ReAI’s AI automation saves significantly more time than Crunch’s rule-based approach.

Making Tax Digital

Both platforms support MTD for VAT with direct HMRC submission. For VAT-registered businesses, either platform handles quarterly VAT returns without needing a bridging tool.

Invoicing

Both platforms include invoicing:

• ReAI offers AI-assisted payment matching, recurring invoices, quotes and bulk invoicing
• Crunch provides standard invoicing with templates, recurring invoices and expense attachment

ReAI has a slight edge on automation (AI-powered payment matching), while Crunch’s invoicing is functional and integrated with the accountant-reviewed workflow.

Bank Feeds

Both platforms connect to UK banks via Open Banking, providing reliable, real-time transaction feeds. Coverage of UK business banks is comparable.

The difference is what happens after the transactions arrive:

• ReAI – AI categorises transactions automatically, learning from corrections
• Crunch – transactions require manual categorisation or rule setup, with periodic accountant review

Payroll

ReAI includes integrated payroll with PAYE, NIC, pension auto-enrolment and RTI submissions.

Crunch offers payroll on limited company plans, but it is handled by the Crunch team rather than as a self-service feature. Payroll is included in the limited company package, whereas sole traders and partnerships do not have access (as they typically do not run payroll).

Reporting

Crunch’s reports are designed to be reviewed alongside accountant guidance rather than as standalone management tools. ReAI’s reporting is built for self-service analysis.
