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; Workiva pricing is quoted per solution and per user and is not published, and because moving a filing cycle off the platform carries deadline risk, renewal negotiations favour the vendor heavily.

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

Workiva

  • Pricing is quoted per solution and per user and is not published, and because moving a filing cycle off the platform carries deadline risk, renewal negotiations favour the vendor heavily.
  • Cost is difficult to justify for smaller filers whose reporting burden is a single 10-K a year, where an outsourced financial printer is cheaper.
  • Getting the initial linked-data structure right is a substantial project, and companies that rush the first cycle end up with links that break and a manual tie-out anyway.
  • The spreadsheet interface is deliberately not Excel and finance teams accustomed to Excel keyboard behaviour and modelling features find it slower for anything analytical.
  • ESG and sustainability modules were added later than the financial reporting core and buyers report them as less mature, so a company buying primarily for CSRD is buying the newer and weaker half of the product.
