RentalBux vs. Neevii
Which MTD Software Is Better for UK Landlords and Sole Traders?
Overall Winner: RentalBux
RentalBux is the confirmed choice for UK landlords and sole traders who need Making Tax Digital compliance from 6 April 2026. It is fully HMRC-recognised for MTD for Income Tax across all three qualifying income types — UK property, foreign property, and self-employment — and combines that compliance with comprehensive property management, automated bookkeeping, bank feed integration, and a permanently free plan for single-property landlords. Neevii is an early-stage, AI-assisted accounting and bookkeeping app for UK small businesses, available on web and Android. It helps users track income and expenses, create invoices, and prepare Self Assessment. However, as of 6 April 2026, Neevii does not appear on HMRC's recognised software list for MTD for Income Tax (ITSA) and does not document the ability to submit MTD quarterly updates directly to HMRC. For any landlord or sole trader who must be compliant from 6 April 2026, RentalBux is the only confirmed option between the two.

What Is RentalBux? What Is Neevii?
What Is RentalBux?
All-in-One MTD Software for Landlords and Sole Traders
RentalBux is an all-in-one property management, accounting, and Making Tax Digital compliance platform built specifically for UK landlords, letting agents, and self-employed individuals. Designed with direct input from accountants who specialise in property and sole trader tax, RentalBux covers everything from tenancy management and rent collection to full bookkeeping with a pre-configured chart of accounts tailored to the property sector.
RentalBux is fully HMRC-recognised for Making Tax Digital for Income Tax across all three qualifying income categories: UK property income, foreign property income, and self-employment. This makes it one of the only landlord-specific MTD software platforms that can handle a landlord who also runs a sole trader business, all from a single subscription.
A major differentiator is RentalBux's pricing model: single-property landlords can use the platform completely free until March 2028, making it one of the most affordable HMRC-approved MTD software options for landlords entering the MTD regime.
What Is Neevii?
Neevii is an AI-powered accounting, bookkeeping, and invoicing app for UK small businesses, freelancers, sole traders, and limited companies. It is available on the web and as an Android app on Google Play. Neevii's stated purpose is to help smaller businesses track income and expenses automatically, categorise transactions using AI assistance, create and send professional invoices, and prepare Self Assessment and other HMRC-ready reports — all in one place, without the complexity of enterprise accounting tools.
As of 6 April 2026, Neevii does not appear on HMRC's official recognised software list for Making Tax Digital for Income Tax. Its website describes HMRC-ready Self Assessment workflows but does not document the ability to submit MTD quarterly updates directly to HMRC or a connection to HMRC's MTD APIs. No pricing is publicly displayed on its website — the subscription page is referenced but pricing details are not publicly available without accessing the app or signing up. Neevii has no documented Trustpilot profile, no independent review data, and a very lean web presence consistent with an early-stage product.

Making Tax Digital Compliance
How RentalBux Handles MTD Compliance
RentalBux supports all three MTD qualifying income categories: sole trader income, UK property income, and foreign property income. This makes it suitable for landlords who also earn self-employment income, eliminating the need for separate software. Most accounts are pre-mapped to HMRC Self-Assessment boxes. RentalBux also supports agent filing, allowing accountants or letting agents to submit MTD returns on behalf of their landlord clients.
Neevii's Position on MTD ITSA
Neevii helps prepare Self Assessment and describes its workflows as "HMRC-ready." However, as of 6 April 2026, Neevii does not appear on HMRC's official recognised software list for MTD for Income Tax, and its website does not document MTD quarterly update submission capability or a live connection to HMRC's MTD Income Tax APIs. The platform's described capabilities — income tracking, expense categorisation, invoice management, and Self Assessment preparation — are consistent with bookkeeping and tax preparation software, but fall short of confirmed HMRC-recognised MTD ITSA submission.
| Feature | RentalBux | Neevii |
|---|---|---|
| HMRC Recognised (MTD ITSA) | Yes | No |
| MTD Quarterly Updates | Yes | No |
| Final Declaration | Yes | No |
| Digital Record Keeping | Yes | Yes |
| Digital Links Compliant | Yes | No |
| Sole Trader Income | Yes | Yes |
| UK Property Income | Yes | No |
| Foreign Property Income | Yes | No |
| Multiple Income Streams | Yes | No |
| Agent Filing on Behalf | Yes | No |
Winner: RentalBux — RentalBux is confirmed HMRC-recognised and live for MTD ITSA quarterly submissions. Neevii is not listed on HMRC's recognised software list as of 6 April 2026. For any landlord or sole trader who is mandated to comply from this date, RentalBux is the only confirmed option between the two.
Property Management
RentalBux: Property Management
RentalBux provides comprehensive property portfolio management with tenant management, rent tracking, property expense allocation, and support for multiple properties. A standout feature is its joint ownership and profit-sharing capability: landlords can define ownership percentages once, and RentalBux automatically splits rental income and expenses. RentalBux also supports HMO properties, automatically creating individual units.
Neevii: No Property Management Features
Neevii does not offer any property management functionality. It is a general accounting and bookkeeping tool designed for freelancers, small businesses, and limited company directors — not landlord-specific workflows. Landlords who need property portfolio management, tenancy tracking, rent collection, or compliance reminders will find nothing in Neevii's documented feature set that addresses these needs.
| Feature | RentalBux | Neevii |
|---|---|---|
| Property Portfolio Management | Yes | No |
| Tenant Management | Yes | No |
| Rent Tracking | Yes | No |
| Property Expense Allocation | Yes | No |
| Multiple Property Support | Yes | No |
| HMO Property Support | Yes (auto-creates units) | No |
| Joint Ownership/Profit Sharing | Yes (auto-split by %) | No |
| Maintenance Tracking | No | No |
| Tenant Screening | No | No |
| Compliance Document Alerts | Yes | No |
| Arrears Tracking | No | No |
Winner: RentalBux — Neevii offers no property management features. For landlords, RentalBux is the only option between the two that provides any landlord-specific capability.
Bookkeeping, Accounting & Digital Record Keeping
RentalBux: Structured Accounting
RentalBux includes a pre-built chart of accounts specifically designed for landlords and sole traders, covering rental income, mortgage interest, insurance, property repairs, professional services, utilities, and tenant deposits. All accounts are pre-mapped to HMRC Self-Assessment boxes. The platform supports cash basis accounting, bank reconciliation, and journal entries.
Neevii: AI-First Bookkeeping for Small Businesses
Neevii's core value proposition is AI-assisted bookkeeping. It tracks income and expenses automatically, uses AI assistance to categorise transactions, and guides users through HMRC-ready Self Assessment workflows. The platform is deliberately positioned as simple and guided, avoiding the complexity of enterprise accounting tools. Invoicing is built in. However, bank feed or Open Banking integration is not documented on Neevii's website, and there is no documented chart of accounts, journal entries, or formal accounting report output.
| Feature | RentalBux | Neevii |
|---|---|---|
| Cash Basis Accounting | Yes | No |
| Chart of Accounts (Pre-built, Landlord-Tailored) | Yes (pre-built + custom) | No |
| Journal Entries | Yes | No |
| Bank Reconciliation | Yes | No |
| Automated Bank Feeds | Yes (Major UK banks) | No |
| Open Banking Integration | Yes | No |
| Double-Entry Bookkeeping | Yes | No |
| HMRC Box Pre-Mapping | Yes | No |
| Xero Integration | No | No |
| Spreadsheet Import/Export | Yes | No |
| Digital Record Storage | Yes | No |
Winner: RentalBux — RentalBux offers a significantly more comprehensive bookkeeping infrastructure, including bank feeds, a landlord-tailored chart of accounts, formal accounting reports, and confirmed MTD ITSA digital record-keeping. Neevii's AI categorisation is a genuine strength, but the broader bookkeeping depth is not documented.
Invoicing, Expense Tracking
RentalBux: Expense Management
RentalBux includes OCR receipt capture, structured expense tracking with landlord-specific categories, auto-categorisation, invoice creation with customisable branding, and payment tracking with reminders.
Neevii: AI-Assisted Categorisation as Core Differentiator
Neevii's defining feature is AI-assisted transaction categorisation. The platform automatically tracks income and expenses and uses AI to categorise transactions, reducing the manual effort of bookkeeping for freelancers and small business owners. Invoicing is built in. The platform is designed for users who want guidance and automation rather than manual accounting.
| Feature | RentalBux | Neevii |
|---|---|---|
| Invoice Creation & Sending | Yes | Yes |
| Invoice Customisation/Branding | Yes | Yes |
| Online Payment Collection | Yes | No |
| Payment Tracking/Reminders | Yes | No |
| Expense Tracking | Yes | Yes |
| Receipt Capture (OCR/Photo) | Yes | No |
| Expense Categorisation | Yes | Yes |
| Automated Transaction Matching | Yes | No |
| Mileage Tracking | No | No |
| AI Auto-Categorisation | Coming soon | Yes |
Winner: RentalBux has richer overall invoicing and expense management capability. For landlords, RentalBux's landlord-specific expense categories and receipt capture are the more relevant strengths.
Reporting & Tax Forecasting
RentalBux: Formal Accounting Reports
RentalBux produces structured financial reports including profit & loss statements, balance sheets, journal reports, ledger reports, and trial balances. Smart categorisation helps ensure accuracy.
Neevii: HMRC-Ready Reporting for Self Assessment
Neevii helps prepare HMRC-ready Self Assessment reports, organising income and expenses into the formats needed for tax filing. No formal accounting reports — profit and loss statements, balance sheets, or trial balances — are documented on Neevii's website. The platform's focus is on guided Self Assessment preparation rather than formal management accounting output.
| Feature | RentalBux | Neevii |
|---|---|---|
| Profit & Loss Report | Yes (formal) | No |
| Balance Sheet | Yes | No |
| Trial Balance | Yes | No |
| Dashboard/Overview | Yes | No |
| Real-Time Financial Data | Yes | No |
| Cash Flow Reporting | No | No |
| Tax Estimate/Forecast | Yes | No |
| AI-Powered Features | Coming soon | Yes |
Winner: RentalBux — RentalBux provides a full suite of formal accounting reports. Neevii focuses on Self Assessment preparation workflows. For landlords who need financial insight and formal reporting, RentalBux is the stronger option.
Collaboration & Mobile Apps
RentalBux's Collaborative Features
RentalBux enables agent filing, which gives accountants and letting agents the ability to submit directly on a landlord's behalf.
Neevii: Web and Android Only — No Documented Agent Access
Neevii is available on the web and Android (Google Play). There is no iOS app. Agent or accountant access is not documented on Neevii's website. Given the platform is designed for small businesses managing their own records, a multi-client agent workflow does not appear to be part of its current offering. Support channels are not clearly documented on the website beyond a general contact reference.
| Feature | RentalBux | Neevii |
|---|---|---|
| Accountant/Advisor Portal | Yes | No |
| Multi-User Access | Yes | No |
| Agent Filing on Behalf | Yes | No |
| Bank Integration | Yes | No |
| Platform | iOS, Android | Web, Android |
| Web Browser Access | Yes | Yes |
| FCA Regulated | Yes | No |
| GDPR Compliant | Yes | Yes |
Winner: RentalBux — RentalBux is available on all platforms including iOS, supports agent filing, and has a documented multi-client accountant dashboard. Neevii is Android-only with no documented agent access or accountant workflow. iOS users and accountants managing multiple clients cannot use Neevii.
Ease of Use, Support & Security
RentalBux: Guided Workflows
RentalBux uses guided workflows, clear dashboards, and no accounting jargon. The platform offers phone support, email/chat support, and a help centre with guides and knowledge base articles.
Neevii's Ease of Use
Neevii presents itself as a simple, guided accounting tool designed for users who are not accountants. Its AI-first approach is designed to reduce the manual effort of bookkeeping. However, Neevii's web presence is very lean — there is no published pricing, no documented support channels, no Trustpilot profile, and no independent third-party reviews available as of 6 April 2026. The platform is available on Google Play and the web, suggesting it is in early stages of market development.
| Feature | RentalBux | Neevii |
|---|---|---|
| Phone Support | Yes | No |
| Chat Support | Yes | No |
| Email Support | Yes | No |
| Help Centre/Knowledge Base | Yes | No |
| FCA Regulated | Yes | No |
| Enterprise-Grade Security | Yes | No |
RentalBux Features
Sole Trader Income Support for MTD
RentalBux is one of the few landlord-focused MTD software platforms that supports self-employment income alongside UK and foreign property income within a single account. Landlords who also run a trade, consultancy, or freelance business can manage all quarterly submissions from one dashboard. Landlord Studio covers property income only.
Custom Chart of Accounts for Landlords
A property-tailored chart of accounts covering rental income, mortgage interest, insurance, repairs, utilities, letting agent fees, and more — all pre-mapped to HMRC Self-Assessment boxes. No setup required; the system is ready to use from day one. Landlord Studio has no equivalent.
Agent Filing on Behalf of Landlords
Letting agents and accountants can submit MTD quarterly updates and the Final Declaration on behalf of landlord clients directly from the platform. Landlord Studio allows accountant access but does not support submission on the landlord's behalf.
Branded Invoice Creation
Invoice creation with customisable branding for service charges and commercial landlords. Not available in Landlord Studio.
AI-Powered OCR Receipt Capture with Auto-Categorisation (Coming soon)
RentalBux's AI will read uploaded receipts and categorise the expense automatically against the pre-built chart of accounts. Landlord Studio's Smart Scan extracts dates and amounts but does not include AI-driven expense categorisation.
Formal Accounting Reports
Balance sheet, trial balance, ledger reports, and journal reports. Landlord Studio does not produce these natively.
Free Plan Including MTD Submissions Until March 2028
RentalBux's free single-property plan includes MTD quarterly submissions. Landlord Studio's free GO plan covers property management for up to three units but requires a paid PRO plan (from £12/month) to access MTD submission functionality.
Unique Features Only Neevii Offers
Live AI-Assisted Transaction Categorisation
Neevii's AI categorisation is live and functional today — this is described as a core feature of the platform, not a Coming Soon item. For small business users who want their transactions automatically categorised without manual selection, this reduces day-to-day bookkeeping effort. RentalBux has AI categorisation in development but it is not yet live.
Designed Specifically for Early-Stage Small Businesses and Side Incomes
Neevii explicitly positions itself for "small businesses, side incomes, and early-stage companies that want simple, guided accounting without unnecessary enterprise features." This deliberate simplicity and low-friction onboarding may suit freelancers or micro-business owners who find larger platforms overwhelming; a meaningful distinction from RentalBux, which carries more accounting depth.
Limited Company Director Support
Neevii documents support for limited company directors alongside sole traders making it relevant for directors who want simple bookkeeping for their personal finances alongside their company income. Note that limited companies are exempt from MTD for Income Tax.
Who Should Choose RentalBux?
RentalBux is a strong fit if you:
Landlords with Mixed Income Streams
If you earn from both property and self-employment, RentalBux handles sole trader income alongside UK and foreign property income in a single MTD-compliant platform.
Joint Owners and Family Portfolios
The automated profit-sharing split is a standout feature. Define ownership percentages once and RentalBux calculates each owner's share automatically.
Budget-Conscious Landlords Entering MTD
Free MTD software for single-property landlords until March 2028, with no upfront commitment.
Landlords Who Want Proper Accounting Structure
Chart of accounts, journal entries, profit & loss, balance sheet, and trial balance give RentalBux a structured accounting foundation.
Accountants and Letting Agents
Agent filing on behalf, multi-user access, and spreadsheet import make RentalBux practical for professionals managing multiple landlord portfolios.
Commercial Landlords and HMO Owners
Invoice creation with branding for service charges, plus automatic HMO unit creation and tenant management.
Who Should Choose Neevii?
Neevii may be worth considering for:
Freelancers and Micro-Business Owners Below the MTD Threshold
For sole traders with qualifying income below £50,000 who are not yet mandated for MTD ITSA, Neevii's AI-assisted bookkeeping and Self Assessment preparation may be sufficient for their current needs — provided its future MTD capability is confirmed when they become mandated.
Early-Stage Small Businesses Wanting Simple AI Bookkeeping
For very small businesses, side incomes, and limited company directors who want a lightweight, guided bookkeeping tool without accounting complexity, Neevii's AI-first approach may reduce administrative burden.
Android Users Who Want Simple Bookkeeping and Invoicing
For Android users who need basic invoicing and expense tracking integrated with their Self Assessment preparation, Neevii's Android app provides that in a single tool.
Users Monitoring Neevii's MTD ITSA Development
For users who are attracted to Neevii's simplicity and want to adopt it when and if HMRC recognition for MTD ITSA is confirmed, it may be worth following — with a confirmed alternative such as RentalBux in place in the meantime.
