Both BizHub365 and KashFlow are designed with UK businesses in mind, but they take very different approaches to business management software. This comparison covers UK tax compliance, pricing, payroll, integrations, automation, and support quality — so whether you're a sole trader, a growing SME, or an accountant managing multiple clients, you can make an informed choice. We've written this as honestly as we can: where KashFlow genuinely excels, we say so.
Where BizHub365 wins
BizHub365 combines accounting, CRM, payroll, inventory management, bookings, and AI automation under a single subscription. KashFlow is primarily an accounting and payroll tool, meaning businesses that need CRM, stock control, or booking management must pay for and maintain separate software — adding cost and complexity. With BizHub365, your sales pipeline, invoices, stock levels, and payroll all live in one place and share the same data, eliminating manual duplication.
BizHub365 is purpose-built for the full UK compliance landscape: MTD for VAT, Making Tax Digital for Income Tax Self Assessment (ITSA), and Real Time Information (RTI) payroll submissions are all handled natively without needing bridging software or third-party add-ons. As HMRC's MTD roadmap continues to expand, BizHub365's compliance infrastructure is designed to grow with it — a meaningful advantage for businesses planning ahead.
BizHub365 includes unlimited users within a single business subscription, so adding team members, bookkeepers, or accountants costs nothing extra. KashFlow's pricing structure charges incrementally as your needs grow — particularly relevant if you run a team and want your accountant to have direct access. For growing SMEs, the cost difference over 12–24 months can be significant.
BizHub365 includes native AI features across the platform: intelligent receipt scanning, automatic bank transaction categorisation, cash flow forecasting, and content generation tools. These aren't bolt-on extras — they are woven into day-to-day workflows to reduce manual data entry and flag anomalies early. KashFlow offers bank feeds and basic automation, but does not match the depth of AI-driven assistance available in BizHub365.
BizHub365 connects natively with 18+ e-commerce platforms including Shopify, Amazon, eBay, Etsy, and WooCommerce, making it a strong choice for product-based businesses selling across multiple channels. It also offers a multi-tenant accountant dashboard, allowing accounting practices to manage all their clients from a single login — and a white-label reseller system for partners who want to launch a branded platform. KashFlow does offer an accountant-focused view, but lacks the breadth of e-commerce integrations and the white-label capability.
Where KashFlow has an edge
KashFlow has been serving UK small businesses since 2005 and was acquired by IRIS Software Group — one of the UK's most established accounting software providers. That pedigree means a mature, stable accounting core, a large community of UK accountants already familiar with it, and a well-documented track record. For businesses whose accountant already uses KashFlow, the familiarity and ecosystem can reduce onboarding friction.
Because KashFlow focuses primarily on accounting and payroll, its interface is deliberately streamlined for users who simply want to raise invoices, reconcile their bank, and submit VAT returns — without navigating a broader platform. Users who find all-in-one platforms overwhelming may appreciate KashFlow's more focused scope, particularly micro-businesses with very simple financial needs.
KashFlow benefits from a well-established network of certified KashFlow accountants and bookkeepers across the UK. If you want to easily find a local or specialist accountant already trained on the software, KashFlow's partner directory makes that straightforward — a genuine practical advantage for business owners who prefer to outsource their finances to a local professional.
As part of the IRIS Software Group, KashFlow integrates tightly with other IRIS products used widely in UK accountancy practices — including IRIS Accounts Production, IRIS Personal Tax, and related tools. For businesses whose accountant operates primarily within the IRIS ecosystem, this tight integration can streamline the year-end and self assessment process considerably.

|---|---|---|---|
| HMRC MTD for VAT | Both platforms support MTD-compliant VAT submissions directly to HMRC with no bridging software required. | ||
| MTD for Income Tax Self Assessment (ITSA) | BizHub365 includes native ITSA support; KashFlow's ITSA readiness relies on integration with the wider IRIS platform. | ||
| RTI Payroll (HMRC Real Time Information) | Both platforms support RTI payroll submissions, though KashFlow Payroll is sold as a separate add-on on some plans. | ||
| CRM (Customer Relationship Management) | BizHub365 includes a built-in CRM; KashFlow has no native CRM functionality. | ||
| Inventory and Stock Management | BizHub365 includes inventory tracking natively; KashFlow offers only basic stock item records within invoicing. | ||
| Unlimited Users | BizHub365 allows unlimited users per subscription; KashFlow charges incrementally based on plan tier and user count. | ||
| AI Receipt Scanning and Categorisation | BizHub365 uses AI to scan, read, and auto-categorise receipts; KashFlow offers receipt capture but without AI categorisation. | ||

| Multi-Tenant Accountant Dashboard | Both offer accountant access; BizHub365's multi-tenant dashboard is purpose-built for practices managing many clients simultaneously. | ||
| White-Label / Reseller Programme | BizHub365 offers a white-label reseller system; KashFlow has no equivalent programme for partners. | ||
| Appointments and Bookings Module | BizHub365 includes an integrated bookings system for service-based businesses; KashFlow does not. | ||
| IRIS Ecosystem Integration | KashFlow integrates tightly with IRIS Accounts Production and related tools — valuable for accountants already in the IRIS ecosystem. |
For UK businesses that need more than just accounting — whether that's CRM, inventory, e-commerce sync, payroll, bookings, or AI automation — BizHub365 offers considerably more per pound spent, with no per-seat cost penalties as your team grows. Its purpose-built HMRC compliance, including native MTD ITSA support, also positions it well for the evolving UK tax landscape. KashFlow remains a credible, mature choice for businesses with straightforward accounting needs, particularly those already embedded in the IRIS ecosystem or whose accountant is a KashFlow specialist — and its long track record in the UK market should not be underestimated. Ultimately, if you're after an accounting-only tool with a familiar UK pedigree, KashFlow does what it says on the tin; but if you want a single platform to run your whole business without paying per user or per module, BizHub365 is the stronger all-round proposition for most UK SMEs.
Is BizHub365 fully compliant with HMRC's Making Tax Digital (MTD) requirements?
Yes. BizHub365 is built natively for HMRC's MTD requirements, covering MTD for VAT and MTD for Income Tax Self Assessment (ITSA). VAT returns and RTI payroll submissions are made directly to HMRC from within the platform — no bridging software or third-party add-ons are required.
Does KashFlow support Making Tax Digital for Income Tax (MTD ITSA)?
KashFlow's core platform has historically focused on MTD for VAT and RTI payroll. For full MTD ITSA support, users typically need to work within the broader IRIS software ecosystem. If MTD ITSA readiness is a priority — especially as the mandation dates approach — it is worth confirming the current scope directly with KashFlow before committing.
How does BizHub365 pricing compare to KashFlow for a small team of five people?
BizHub365 charges a single business subscription with unlimited users, so a team of five costs no more than a team of one. KashFlow's pricing is tiered and can increase as your user count or feature requirements grow. For teams of three or more, BizHub365 is typically more cost-effective — especially when you factor in the additional modules (CRM, inventory, bookings) that would require separate tools alongside KashFlow.
Which platform is easier to use if I'm not an accountant?
Both platforms are designed for non-accountants, and KashFlow's focused, streamlined interface is genuinely easy to pick up for basic invoicing and VAT tasks. BizHub365 covers more ground, but is built with plain-language dashboards, AI-assisted data entry, and guided workflows to keep things accessible. If you need only basic accounting, KashFlow's simplicity is appealing; if you want to manage more of your business in one place without a steep learning curve, BizHub365 holds up well.
Can I switch from KashFlow to BizHub365 without losing my data?
Yes. BizHub365 supports data migration from major UK accounting platforms, and the onboarding team can assist with importing your chart of accounts, customer and supplier records, and opening balances. It is advisable to time a switch at the start of a new VAT period or financial year to keep your records clean, and BizHub365's support team can guide you through the process.
