Choosing between IRIS Elements vs BrightManager for your accounting practice often comes down to these five critical questions:
- Do you need a full accounts production and tax filing suite, or is your primary challenge managing workflows, tasks, and client communication?
- Is your practice strictly UK/Ireland-based, or do you serve clients internationally?
- Do you want rigid, compliance-driven automation, or flexible workflows you can adapt to how your team actually works?
- Are you looking for visual task management with calendar views and drag-and-drop scheduling, or do structured list-based workflows suit you better?
- Is transparent client collaboration and automated billing a priority, or are statutory accounts and tax returns your main bottleneck?
In short, here’s what we recommend:
👉 IRIS Elements is the heavyweight compliance platform for UK accountancy firms that need end-to-end statutory accounts production, tax filing, and AML checks under one roof. Built by IRIS Software Group (serving over 100,000 customers globally), it offers a unified cloud architecture where a single client record links accounts production and tax in one cohesive workflow with real-time data synchronisation, alongside modules for AML, company secretarial, and practice management.
With an over 98% HMRC acceptance rate, AI-powered anomaly detection, and tiered editions scaling from sole practitioners to large enterprises, IRIS Elements is purpose-built for firms whose primary pain point is compliance. However, its practice management capabilities are newer (the Enterprise tier launched in late 2024), the learning curve can be steep for complex features, and its rigid 90-day cancellation policy for annual contracts has frustrated users.
👉 BrightManager (formerly AccountancyManager) excels as a compliance-driven practice management tool built specifically for UK and Ireland accountants. Acquired by Bright Software Group in 2022, it automates client onboarding, chases clients for missing records via email and SMS, tracks statutory deadlines, and monitors job profitability.
Its automated communication engine and “Client Timeline” audit trail are impressive, and it integrates tightly with other Bright products like BrightPay. That said, BrightManager’s document management has limitations in organisation, it lacks visual workflow tools like Kanban boards, and it is primarily focused on the UK and Ireland market.
Both platforms are rooted in UK compliance, and both do an excellent job automating statutory workflows. But for firms that want flexible, visual practice management with powerful automation, international reach, and a intuitive experience, there’s a third option worth considering.
👉 Uku takes a different approach entirely. Instead of building around compliance filing, Uku is built around how accounting teams actually work day to day. Its three-level workflow system (task templates, client task plans, and individual tasks) can automate the vast majority of a firm’s recurring work, and its modular design means firms can start with just CRM and tasks and add features as they grow.
The platform’s standout capability is its automated billing engine, which reduces invoice preparation from days to about 30 minutes by generating invoices directly from tracked time and client contracts. A client portal with company branding provides a unified workspace where clients and accountants collaborate on the same tasks, making document collection and communication effortless.
Created from the ground up to be international, Uku serves 1000+ clients globally with support for 12 languages and multi-currency capabilities, and is a system your team will actually enjoy using.

The fundamental divide: Compliance filing vs practice management
IRIS Elements is, at its core, a compliance production platform.
Its greatest strengths are accounts production with automated iXBRL tagging, direct HMRC and Companies House filing, and a unified client record that connects tax, accounts, AML, and company secretarial modules. If your practice’s biggest bottleneck is preparing and filing statutory accounts and tax returns, IRIS Elements addresses that directly.
The practice management module exists to support the compliance workflow, not the other way around.
BrightManager sits in the middle.
It doesn’t produce accounts or file tax returns (those sit in separate Bright products), but it is tied to UK statutory compliance. Its automation engine generates task lists driven by HMRC and Companies House deadlines, automatically chases clients for missing records, and tracks every interaction in a timestamped audit trail. It’s practice management, but through a compliance-first lens.
Everything revolves around statutory deadlines, and the system is designed to ensure nothing falls through the cracks.
Uku approaches the problem from the opposite direction.
Instead of starting with compliance deadlines and working backward, Uku starts with how your team actually works and builds automation around that. Its three-level workflow structure (master templates that become client-specific plans that generate individual tasks) means you define your processes once and let the system handle the rest.
Whether those processes are tied to statutory deadlines or internal service agreements, Uku adapts to your firm’s needs rather than requiring your firm to adapt to it.
Critically, Uku’s modular approach means firms don’t need to implement everything at once; they can start with the basics and activate additional modules as the team is ready, eliminating the substantial upfront configuration that larger platforms demand.
For firms that need statutory accounts production and tax filing, IRIS Elements is the best option. But for firms whose primary challenge is managing workflows, tracking time, billing clients, and keeping their team organized, Uku offers a more flexible and intuitive solution.
Workflow management reveals different philosophies
IRIS Elements offers a practice management module with job and task management and a customizable dashboard. Jobs can be created as one-off or recurring, with tasks broken into granular assignments for specific team members.
Source: IRIS Elements
The Enterprise tier includes resource scheduling and full time and expenses tracking, while the Professional tier offers time tracking as an optional add-on. It’s a capable system, though users migrating from IRIS’s legacy desktop software have reported friction with the transition.
BrightManager relies on structured, rule-based task lists.
When a financial period ends, the system automatically generates the required compliance tasks and assigns them to team members based on the firm’s structure. Workflow templates break jobs into step-by-step subtasks, and progress is tracked through visual progress bars and column filters.
A recent UI update introduced a side panel for updating task details without leaving the main list. It works well for compliance-driven workflows, but firms that want a more dynamic, visual view of their workload may feel constrained by the list-based approach.
Source: BrightManager
Uku gives you both structure and flexibility.
The task template system lets you standardize recurring work across clients, with tasks automatically generated from client custom fields in addition to standard weekly, monthly, quarterly, and yearly recurrence options.
Calendar views and planner boards let you manage daily work visually. Tasks can be dragged and dropped to reschedule them, filtered by client, topic, or team member, and saved as custom views for quick access.
Subtask checklists ensure nothing gets missed within complex jobs, and task dependencies prevent work from starting before prerequisites are complete. All communication stays within tasks, solving the common problem of information being trapped in individual email accounts. Managers get a real-time overview of the entire firm’s workload through customizable dashboards.

The difference becomes clear in daily use. BrightManager tells you what compliance tasks need doing and when. IRIS Elements provides the tools to produce the compliance work itself. Uku helps you manage all your work (compliance-related or not) in a way that keeps your team productive and your clients happy.
Client communication and collaboration take different paths
IRIS Elements provides automated email and SMS communication, with integration into Microsoft Outlook so that all correspondence is captured in the client record.
Its Client Portal allows for secure document sharing, e-signatures, and client Q&A. The system can send automated reminders and records requests, and the Proposal Manager module handles client onboarding with branded proposals and engagement letters.
Source: IRIS Elements
BrightManager is particularly effective here.
Its automated communication engine sends emails and SMS texts to chase clients for missing records, signatures, and tax payments without any manual intervention. The system uses a wide range of client-specific variables to make automated messages feel personal.
The “Client Timeline” logs every interaction (including when a client opens an email), creating an audit trail that protects the firm’s liability. The white-labeled client portal supports e-signatures and document sharing, though some users may find the document management could benefit from more organisational features.
Source: BrightManager
Uku takes a different approach to client collaboration.
Unlike traditional portals where tickets must be connected to work items, Uku’s client portal mirrors the exact same task on both sides. Clients and accountants work on the same item with all communication, actions, documents, logs, and time tracking in one place.
When clients make requests through the portal, notifications appear on the accountant’s dashboard, and they can immediately start tracking time or communicating within that same task.
The portal uses “magic links” for access, meaning clients never need to remember usernames or passwords. Accountants can assign tasks directly to clients through the portal, create document request checklists, and set up automated reminders for overdue items.
Source: Uku
But the portal goes well beyond document collection: firms can create unique menus for each client, run onboarding with forms, share business insight reports, display price lists, embed custom content, and even collect client feedback. Clients can upload documents via drag-and-drop, ask questions, and mark tasks complete, all from a clean, mobile-friendly interface.
What further sets Uku apart is one-click document digitalization. Documents submitted through the portal can be sent directly into accounting software like Xero with a single click. This level of automation for document handling is unique in the practice management space and eliminates the manual forwarding that eats into accountants’ time.
Time tracking and billing show where priorities lie
IRIS Elements includes time tracking in its Enterprise practice management tier as standard, with timers, receipt capture, and utilization targets.
The Professional tier offers time tracking as an optional add-on. It’s functional and feeds into the broader workflow, but billing and invoicing play a supporting role to the platform’s core compliance focus. IRIS Elements is built to produce compliance work, and the time tracking is there to support resource management rather than drive revenue insights.
BrightManager offers built-in time tracking with a stopwatch and manual entry options.
Source: BrightManager
Its strength is the connection between time tracking and profitability analysis. The Insights Hub provides seven reports covering productivity, aged WIP, and client profitability.
Users can generate invoices directly from accumulated WIP data, and the system provides profitability analysis that compares chargeable time against client revenue to highlight which jobs are performing well. It’s a solid setup for firms that want to understand their profitability.
Uku treats time tracking and billing as a central part of practice management rather than an add-on.
Users can track time through multiple methods including a stopwatch, manual entry, or bulk time allocation across multiple tasks, with 90% of time tracking actions being one-click, dramatically reducing the admin overhead that makes other platforms frustrating to use daily.
The automated billing engine is where Uku separates itself from both IRIS Elements and BrightManager. The system supports complex price lists based on quantity, time, material, and ranges with different rates for different periods.
Source: Uku
Rounding rules can be configured by entry, team, client, or month. For instance, a one-minute unplanned call can be automatically billed as 15 minutes, ensuring firms properly capture revenue from interruptions and ad-hoc work.
Everything is automated through “contracts” where billing rules are set up once, and time tracking automatically calculates billable amounts in real-time. For firms that currently spend days preparing invoices, Uku reduces that process to about 30 minutes, even when invoicing over 100 clients.
Uku’s billing system also tracks both sales prices and actual cost prices, giving managers direct visibility into whether employees are profitable. If an employee costs €30/hour but bills at €45/hour, managers can see the margin instantly.
When employees work eight hours but only six are billable, Uku’s BI Reporting provides insights into whether the issue is employee efficiency, client difficulty, or pricing structure, with real-time visual reports and alerts that prevent firms from discovering losses 30 days too late.
BI Reporting offers three levels of depth (summary, tasks, and time), advanced filters, saved report templates, and specific business analytics reports that provide detailed performance metrics. Customers report seeing ~20% more profit after discovering outdated agreements where they were billing far less than the actual work required.
The learning curve and daily experience matter more than feature lists
IRIS Elements aims for an intuitive cloud-native interface, and IRIS states that users should be able to log in and use it “without looking at the manual.”
For the core tax and accounts modules, this is largely true for users familiar with accounting compliance software. However, users migrating from legacy IRIS desktop products have reported friction, and some of the newer Enterprise-tier features are still being refined.
The Essentials tier notably excludes direct telephone support (it must be purchased separately), which can make the learning experience harder for smaller firms.
BrightManager can have a steeper initial learning curve due to its comprehensive, rule-based system. Mapping a firm’s existing processes into the software can require a meaningful time investment.
The breadth of features may feel overwhelming for practices with simpler needs, and the interface relies heavily on list views. However, once the initial setup is complete, the system becomes highly capable and runs much of the practice on autopilot. Customer support channels include phone, email, and live chat, which helps during the implementation phase.

Uku is consistently praised for its intuitive design and fast & flexible deployment.
The platform’s modular approach means firms don’t need to configure everything upfront. They can start with just CRM and tasks on day one, then activate additional modules like automated billing, client portal, or BI Reporting as the team is ready.
Many Uku customers are transitioning from Excel, and the platform is designed to make that shift painless: firms can import their existing data and have automated task plans running within an hour. This “from Excel to greatness” path directly addresses the risk aversion that keeps many accounting firms stuck on spreadsheets.
Uku provides 90 minutes of free onboarding assistance and assisted import across all plans, while the “Mini Uku” Chrome extension lets users track time and manage tasks without leaving whatever website they’re working on.
The fact that Uku offers a free Solo plan and a 14-day trial means firms can test the full platform with real work before committing. The platform is also SOC 2 Type I compliant with TLS 1.3 encryption and data hosted on enterprise-grade cloud servers in Germany (EU).
For firms where ease of adoption matters (and it should, because the best practice management software is the one your team actually enjoys using), Uku has a meaningful advantage. Even resistant team members who initially push back on tracking time tend to become the biggest champions after a month of use.
Pricing models reflect who each platform is built for
IRIS Elements uses a modular pricing model where firms select individual applications and pay based on both the product tier and the number of active clients.
Base prices start very low (Accounts Production from £4/month, Tax from £10/month), but costs scale with client volume and feature complexity.
The Essentials tier charges extra for telephone support. Annual contracts carry a strict 90-day notice period for cancellation, which has been a concern for some users. Additional costs include per-client fees for Company Secretarial services (from £6.45/client) and usage fees for AML checks.
BrightManager charges £42 + VAT per user per month (with a 20% discount for annual billing).
The Standard plan supports up to 12 users and includes the full feature set: automated communications, task management, onboarding, client portal, time tracking, profitability tracking, and AML checklists. Enterprise pricing (12+ users) is custom.
Additional costs include AML credits (from £3.21 each), white-labeled portal customization (£20.50/month), and SMS credits (£0.07 each). Monthly plans require no contract, while annual plans carry a 12-month commitment.
Uku offers four tiers starting with a free Solo plan for solo practitioners (1 user, 25 clients).
The Team plan starts from £29/member/month and includes teamwork, email integration, client portal, unlimited clients, custom fields, and integrations. The Elite plan at £39/member/month adds Client Budgeting, Document Management, e-signatures, Google Drive/OneDrive integration, workforce management, and audit logs.
Both annual and monthly billing options are available, with annual billing saving 23%, and pricing is available in multiple currencies (€, $, and £). The 14-day free trial requires no credit card.
For firms evaluating total cost of ownership, the comparison is nuanced. IRIS Elements can be affordable for basic compliance work but scales up quickly with added modules and clients.
BrightManager’s per-user pricing is straightforward but the add-on costs for AML, SMS, and portal branding add up.
Uku’s per-member pricing includes unlimited clients at every paid tier, which makes costs more predictable as the firm grows. Uku also offers flexible monthly pricing. This means firms can pay from £29/month to test the system rather than committing to large upfront annual payments, which makes it easier to evaluate the platform with real work before scaling up.

Sometimes the best practice management software isn’t the one with the most compliance features. It’s the one that helps your team do their best work, every day.
