IRIS KashFlow vs QuickBooks Online (2026): which should you pick?

Pick IRIS KashFlow if

• Fits if you're a UK limited company that wants VAT returns and payroll in one product
• Works for sole traders who sell through Shopify, WooCommerce or Amazon

Look elsewhere if

• Tight if you're on Starter: one user, 10 invoices and 25 bank transactions
• Not for you if you're outside the UK, since VAT goes to HMRC and prices are in pounds
• Watch out: the £1.35 and £2.75 months and the annual prices are new-customer offers
• Pricey if you need more than one user: Business is £27.50 a month plus VAT

Pick QuickBooks Online if

• Fits if your accountant wants to work in the same books as you
• Works for US businesses that expect to add payroll, inventory or project tracking later

Look elsewhere if

• Pricey if you're a small team or need inventory and budgets: $85 a month for 3 users, $140 for Plus with 5
• Watch out: the advertised prices are half off for 3 months only, then $38, $85, $140 or $340 a month
• Tight if you're on the free plan: 2 invoices a month, 1 bank, and no accountant access or mobile app
• Pricey if you need payroll, at $50 a month plus $7 an employee on top
• Skip it if you're outside the US, as these are US plans and prices and other countries have their own sites

IRIS KashFlow

• Built for UK businesses: VAT submission goes to HMRC, and prices are in pounds.
• Starter is limited to a single user, 10 invoices and 25 bank transactions to reconcile; Business lifts those limits.
• The page marks the annual prices (£97 and £178 plus VAT) as discounted offers for new customers only.
• The pricing page names a mobile app but not which operating systems it runs on.

QuickBooks Online

• The advertised prices are a 50% discount for the first 3 months; the plan then renews at $38, $85, $140 or $340 a month.
• Each plan caps users: 1 on Simple Start, 3 on Essentials, 5 on Plus and 25 on Advanced.
• Payroll costs extra: Workforce Payroll alone is $50 a month plus $7 per employee, and Premium is $88 plus $13 per employee.
• These are US prices and plans; Intuit runs separate country sites for Canada, the UK, Australia, India and others.
