The short version

  • Each has a real cost: IRIS KashFlow advertised monthly prices of £1.35 (Starter) and £2.75 (Business) are a 90% promotional discount off the standard £13.50 and £27.50 rates, and the promotion is described as lasting 6 months before reverting; QuickBooks plans cap the number of billed users, so an approver who signs off bills and a manager who only reads reports each consume a seat and can force an upgrade to a higher tier for reasons that have nothing to do with accounting complexity.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

IRIS KashFlow

  • Advertised monthly prices of £1.35 (Starter) and £2.75 (Business) are a 90% promotional discount off the standard £13.50 and £27.50 rates, and the promotion is described as lasting 6 months before reverting
  • Listed prices are in GBP plus VAT, and the platform's plans are built around UK VAT filing rather than other tax regimes
  • Annual pricing is quoted at RRP £162/year (Starter) and £291.50/year (Business) before the same promotional reduction

QuickBooks

  • Plans cap the number of billed users, so an approver who signs off bills and a manager who only reads reports each consume a seat and can force an upgrade to a higher tier for reasons that have nothing to do with accounting complexity.
  • Multi currency is confined to the higher tiers and, once enabled, cannot be turned off and the home currency cannot be changed, so a single foreign currency invoice permanently changes the shape of the file and the plan you must remain on.
  • Inventory is average cost only, with no first in first out or standard costing, so a business whose accounts or tax position depend on a different costing method has to track stock outside the ledger and post adjustments.
  • There is no multi entity consolidation, so a group runs a separate subscription and file per company and consolidates in a spreadsheet, and the cost and the manual consolidation both grow with each new entity.
  • The country edition is selected at setup and cannot be changed afterwards, and the editions differ in tax handling and features, so a business that redomiciles or discovers it chose the global edition rather than a localised one starts a new file rather than switching a setting.

Answered from the vendors’ own pages

IRIS KashFlow: What are IRIS KashFlow's core features across all plans?

All IRIS KashFlow plans include unlimited quotes, online VAT submission, mobile app access, 50+ reports, bank feeds, receipt capture, multi-currency support, and payroll for up to 5 employees.

Source
QuickBooks: Which country editions actually exist?

Intuit sells localised editions principally for the United States, United Kingdom, Canada and Australia, with a global edition for other markets that has lighter tax localisation. Check that your country has a genuine localised edition before assuming filing support, and note the edition cannot be changed after setup.

IRIS KashFlow: Are there promotional discounts for new IRIS KashFlow customers?

Yes, new customers receive a 90% discount for 6 months on both Starter and Business monthly plans.

Source
QuickBooks: Does the subscription include payroll?

No. Payroll is a separate subscription with a per employee charge in every market that offers it. Price it alongside the plan rather than after you have committed.

IRIS KashFlow: Can multiple users access IRIS KashFlow on the Starter plan?

No, the Starter plan is limited to single-user access only. Multi-user access requires the Business plan.

Source
QuickBooks: How many users do I get?

It depends on the tier, and the limits are lower than most buyers expect. Accountant access seats are free and separate, but internal approvers and read only reviewers count against the billed limit, so count everyone who needs to sign in before choosing a plan.

QuickBooks: Can my accountant work directly in my file?

Yes, that is one of its main advantages. Accountants use a separate practice console and take a free access seat in your company, which is also why so many practices standardise on it.

QuickBooks: Is QuickBooks Desktop still available?

The desktop line persists in the United States for larger installations, but Intuit stopped selling new subscriptions of the smaller desktop products to new customers and the investment is in the online product. Treat desktop as a legacy path rather than a choice for a new business.

QuickBooks: How hard is it to migrate to or from QuickBooks?

Getting in from another system is well trodden and there are tools and specialists for it, though transaction history usually arrives partially rather than completely. Getting out is the harder direction, because your accountant's working knowledge, your app integrations and years of coded history all have to be reproduced. Most businesses move at a year end for that reason.

QuickBooks: Can it consolidate multiple companies?

No. Each legal entity needs its own subscription and file, and the consolidation happens outside the system. Groups with several entities should price that reality in from the start.
