When weighing up Sleek vs Crunch, the decision usually comes down to how you want your accountant to work alongside you. Sleek bundles full-service accounting with a dedicated UK-based accountant from £60/month, while Crunch starts limited company packages from £90 + VAT/month with a modular approach that lets you add services as you go.

Both platforms are well established, technology-led, and built around making UK compliance simpler. The right choice depends on whether you want one fixed fee covering bookkeeping, VAT, payroll and your year-end accounts, or you prefer to build your plan piece by piece around proprietary software.

If you’d like to learn about a Crunch Alternative that doesn’t break the bank, Sleek’s online accounting services cover the full picture from bookkeeping and VAT through to year-end accounts, with a dedicated accountant included from your entry plan.

Prices shown are the lowest publicly listed rates on each provider’s UK website at the time of writing. Features and pricing can change, so verify before purchase. Sleek’s 50% discount with incorporation is excluded from direct price comparisons to keep like-for-like fairness. The £100 Companies House filing fee took effect from 1 February 2026 and applies to all new UK company registrations.

Both providers offer strong value at their respective entry points. The right fit depends less on the headline number and more on what’s bundled versus what gets added later.

Tip

When comparing accountants, look beyond the starting price. Ask what happens when your revenue grows, you hire your second or third employee, or you register for VAT. Will essentials like payroll, registered office, or VAT filing be bundled, or will they appear as add-ons on your next invoice? Can your accountant support funding rounds, R&D claims, or specialist tax work if you need them later?

The cheapest headline rate can look very different 12 months down the line once add-ons start stacking up. Choosing an accountant that scales cleanly with your business often saves you far more than the monthly fee suggests.

Sleek vs Crunch: Features, pricing, support and more compared

Both Sleek and Crunch position themselves as digital-first online accountants, but their pricing philosophies sit at different ends of the spectrum.

Sleek is built around fixed, inclusive packages designed to keep monthly costs predictable as a business grows. Crunch uses a modular approach where the core accounting plan covers compliance, and individual services like payroll, registered office, and Self Assessment sit alongside as priced add-ons.

Sleek vs Crunch: Pricing comparison

The headline numbers tell only part of the story. What matters is what each fee actually covers once your business starts hiring, registering for VAT, or filing Self Assessments.

Sleek

Sleek offers a fixed monthly fee starting at £60/month for limited companies, billed annually, which covers online accounting, bookkeeping, year-end accounts, Corporation Tax filing, VAT filing, Confirmation Statement filing, Director’s Tax Return, and payroll and pension filing for 1–5 employees. A dedicated UK-based accountant is included from day one.

Two packages are available, Accounting Basic and Accounting Pro, designed around revenue and stage of growth. The structure is simple, scalable, and easy to budget for. New clients on Basic get SleekBooks as standard, while Pro clients get Xero included.

Crunch

Crunch’s Limited Company Pro plan starts at £90 + VAT/month, billed annually. The base plan covers full compliance management, including Corporation Tax, VAT filing, year-end accounts, real-time tax insights, and unlimited support from ACCA-accredited accountants.

Several services sit outside the base plan as priced add-ons:

  • Director payroll above the NI threshold: £18 + VAT/month
  • Employee payroll for up to 5 employees: £18 + VAT/month (rising to £23 for 6–10 and £28 for 11–15)
  • Registered office address: £8 + VAT/month
  • Self Assessment filing: £200 + VAT (one-off)
  • IR35 solution (TwinTrack): £6 + VAT/month
  • Financial Healthcheck: £85 + VAT

A Premier tier from £124 + VAT/month is available for businesses with more complex structures, including alphabet shares, corporate shareholders, property portfolios, sector-specific needs, or turnover above £1 million.

Worked example: how the numbers compare for a £300k turnover limited company

To make the pricing tangible, here’s how Crunch’s published rates stack up for a working limited company with 1 director, 3 employees, and the most common services switched on:

Service

Crunch monthly cost

Limited Company Pro base plan

£90 + VAT

Director payroll (above NI threshold)

£18 + VAT

Employee payroll (up to 5 employees)

£18 + VAT

Registered office address

£8 + VAT

Total

£134 + VAT/month

Figures based on Crunch’s publicly listed rates on crunch.co.uk/pricing and crunch.co.uk/instant-quote at the time of writing. Add-ons such as Self Assessment (£200 + VAT one-off) and IR35 cover are not included in the total above. Actual quotes may vary, and businesses can verify their figure through Crunch’s own instant quote tool.

By comparison, Sleek’s £60/month Basic plan includes payroll and pension filing for 1–5 employees, VAT filing, and the Director’s Tax Return without needing to add them on. Annual billing converts to roughly £720 for the year, against Crunch’s £1,608 + VAT (£134 + VAT × 12) on the comparable setup above.

If a modular setup that you can build up over time suits your business better, Crunch’s approach gives clear visibility on each individual cost. If you’d rather know exactly what your monthly fee covers from the start, Sleek’s bundled pricing keeps the maths simpler.

Sleek vs Crunch: Company incorporation

Both providers offer company formation, but the structure and inclusions differ.

Sleek

Sleek offers two distinct routes to incorporation. The first is a fast, basic limited company registration from £2.99 plus the £100 Companies House filing fee, available via our sister site Limited Companies, and every tier includes a 50% discount on annual accounting.

The second is a fully managed end-to-end formation package from £265 + VAT, which includes:

  • Full managed company formation (Companies House fee included)
  • Registered Office address (Regent Street, London)
  • Director’s service address
  • First Confirmation Statement filing
  • Free business bank account referral

Higher tiers extend further into accounting, tax, payroll, VAT registration, and digital mailroom services.

Crunch

Crunch offers a single company formation product priced at £100, which covers the Companies House registration. Additional services such as registered office, director payroll, and ongoing compliance sit on the wider accounting plans rather than being bundled into the formation product itself.

If you want a quick, low-cost start and you’ll handle compliance separately, Crunch’s flat £100 formation product is straightforward. If you’d prefer everything from registration through to first-year compliance covered in a single managed package, Sleek’s £265 + VAT route consolidates the setup in one place.

Why Sleek might suit businesses planning to scale or claim specialist reliefs

Sleek and Crunch cater to different specialist needs. Here’s where each focuses.

Sleek covers growth-stage and emerging-sector services, including:

Crunch’s specialist offering sits within its Premier tier, focused on bespoke consultancy for limited companies with established complex shareholding structures.

Annual review versus always-on partner

There’s also a difference in tax planning philosophy worth flagging.

Crunch promotes a Tax Optimiser tool that reviews opportunities to reduce a company’s tax bill.

Sleek takes a continuous approach. Rather than periodic reviews, your dedicated accountant works with your numbers throughout the year, identifying allowances and planning opportunities as your business actually changes.

The difference comes down to an annual checkpoint versus an always-on partner.

Dedicated R&D tax credit service

Scaling ecommerce, contractor, or startup operations

Specialist accountants available across all packages

Continuous tax planning

For businesses that have grown into highly bespoke shareholding structures, Crunch’s Premier tier offers tailored consultancy for those specific mechanics. But for those looking for a partner that takes care of every avenue, Sleek might be the better option.

Sleek vs Crunch: Company secretarial services

Crunch vs Sleek: integrations

Sleek and Crunch take different approaches to integrations, reflecting their different software philosophies.

Sleek integrations

Sleek is a Xero Platinum Champion partner. New clients on Basic plans use SleekBooks, our in-house bookkeeping software, while Pro clients get Xero included with full access to the Xero App Store ecosystem.

Through Xero, Sleek clients on Pro plans benefit from:

  • Stripe for invoice payments and automatic reconciliation
  • Shopify with the Xero-built connector for daily sales summaries
  • PayPal as a payment service inside Xero
  • Hundreds more apps via the Xero App Store
  • Full Making Tax Digital recognition for VAT and Income Tax workflows

SleekBooks on the Basic plan delivers the core bookkeeping experience for businesses that don’t need the full Xero ecosystem yet, with the option to switch to Xero on the Pro plan when the business grows into it.

Crunch integrations

Crunch is built around its own proprietary accounting software, which integrates directly with Open Banking and offers a focused set of features for UK small businesses.

Crunch’s headline integrations include:

  • Open Banking connections to major UK banks including HSBC, NatWest, Lloyds, Santander, Monzo, Revolut, Virgin Money, and Zempler
  • CrunchPay for Apple Pay, Google Pay, Direct Debit, and card payments on invoices
  • Brixx for cashflow forecasting
  • TripCatcher for mileage tracking
  • Full HMRC recognition and Making Tax Digital readiness ahead of April 2026

The contrast comes down to ecosystem versus all-in-one. Sleek’s Xero-based setup on Pro plans connects to a wider third-party app marketplace, useful for businesses needing CRM, inventory, or specialist ecommerce tools alongside their accounting. 

Crunch’s proprietary software keeps everything inside a single platform, useful for businesses that want a tighter, simpler stack with fewer moving parts.

Sleek vs Crunch: Onboarding and switching accountants

Switching accountants should feel straightforward, not stressful. Here’s how both providers handle the move.

Sleek onboarding

Switching to Sleek is built around removing the legwork from the client. With Sleek:

  • Free company formation when you also take an accounting package
  • 50% off your accounting package when you incorporate
  • Full setup for Making Tax Digital
  • Bank feeds and app integrations connected for you
  • Complete handover from your previous accountant
  • Guided onboarding call with clear next steps
  • Ongoing support by email, phone, and chat
  • 30-day money-back guarantee

You’re set up to be compliant from day one, with a clear roadmap and a dedicated accountant who knows your business.

Crunch onboarding

Crunch’s onboarding is built around its proprietary software, so the experience starts with the platform itself:

  • Free 14-day trial available before committing to a paid plan
  • Plan selection through the instant quote tool
  • Introduction to a dedicated accountant on Pro and above
  • Bank feeds connected via Open Banking
  • Support via phone, video call, live chat, and email

The experience is platform-led, with the Crunch app at the centre and accountancy support layered on top.

Important to consider

A few things worth thinking about before committing:

  • Both providers offer annual billing options
  • Cash flow planning matters if you’re a new business
  • Check exactly what’s included in your base plan before signing
  • Confirm whether services like payroll, registered office, and Self Assessment are bundled or added later

If you want a fast start with free formation, an MTD-ready setup, and a first-year accounting discount, Sleek removes most of the setup friction. If you’d rather trial the software first before committing to a paid plan, Crunch’s free 14-day trial gives that flexibility.

FAQs on Sleek vs Crunch

Can I switch from Crunch to Sleek mid-financial year?

Yes. You can move your accounting over to Sleek at any point in the year, and we handle the transition with your previous provider on your behalf. Your dedicated accountant will coordinate the handover, transfer your historical data, and make sure no deadlines fall through the gap. Most clients are fully set up within two weeks.

Does Sleek support contractors and IR35 compliance?

Yes. Sleek’s contractor accounting service is built around IR35 expertise, with dedicated accountants who understand how to handle inside vs outside IR35 status. Whether you’re working through your own limited company, transitioning to a new contract, or managing multiple engagements, your accountant will guide you through the right setup and ongoing compliance.

What happens if my limited company becomes dormant?

Sleek will guide you through the process of declaring your company dormant and handle the filings on your behalf. Dormant company accounts are simpler than active ones but still need to be filed with Companies House on time. We help you decide whether dormancy is the right step and manage the paperwork to keep your company on the register.

Does Sleek handle Self Assessment for sole traders and directors?

Yes. Sleek’s Self Assessment tax return service covers sole traders, contractors, and limited company directors. The Director’s Tax Return is included in every Sleek limited company accounting plan from £60/month, so you don’t need to add it as a separate service. Sole traders can take it on a one-off basis or as part of a fuller accounting package.

How does Sleek’s VAT support compare to bundled VAT filing?

Sleek includes VAT filing in its Basic and Pro accounting plans for limited companies from £60/month, with no separate VAT filing fee. Your accountant handles quarterly Making Tax Digital returns, advises on the best VAT scheme for your business, and helps with VAT registration when you cross the threshold. There’s no per-quarter charge or add-on for standard VAT filing.

Does Sleek help me open a UK business bank account?

Yes. Sleek includes a free business bank account referral as part of every incorporation package, with introductions to UK banks that work well with your business setup. For non-UK residents and international traders, we can also help arrange an international business account. This is included at no extra cost when you incorporate through Sleek.

What if I outgrow my current accountant or accounting plan?

Sleek’s plans are designed to scale with your business. You can move between Basic and Pro tiers as your revenue, headcount, or compliance needs change, and your dedicated accountant stays the same throughout. For more complex setups, including multi-entity structures or higher volumes of international transactions, Sleek offers bespoke accounting packages tailored to your needs.
