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; Ottimate nothing is published about price, and quotes are structured by location and invoice volume, so a group with a few high-volume sites and one with many low-volume sites can receive very different numbers for the same total spend

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

Ottimate

  • Nothing is published about price, and quotes are structured by location and invoice volume, so a group with a few high-volume sites and one with many low-volume sites can receive very different numbers for the same total spend
  • The line-item extraction advantage is trained on food and beverage distributor formats, so accuracy on long-tail suppliers, service invoices and one-off vendors falls back to general OCR and needs human review
  • It is an accounts payable layer, not an inventory or recipe costing system, so operators still need Restaurant365 or an equivalent for true plate costing and the value depends on that integration behaving
  • The company has rebranded once already from Plate IQ, and much of the third party comparison material still uses the old name or wrongly attributes it to AvidXchange, which makes independent due diligence unusually hard
  • Payment execution through the platform introduces a dependency on Ottimate for supplier relationships, and moving away later means re-establishing payment details with every vendor rather than simply exporting data
