The short version

  • Each has a real cost: Basware the e-invoicing compliance breadth that justifies the price is worthless to a company operating in a single country, where cheaper AP automation tools will do the same work.; 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

Where each one falls short

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

Basware

  • The e-invoicing compliance breadth that justifies the price is worthless to a company operating in a single country, where cheaper AP automation tools will do the same work.
  • Implementation is a substantial integration project involving ERP connectors, supplier onboarding and country-by-country compliance configuration, and it is priced and timed accordingly.
  • The user interface is dated next to newer accounts payable products, and approvers outside finance find it unintuitive, which slows the very cycle times the system is bought to improve.
  • Supplier onboarding onto the network is the hidden effort: the touchless processing rate depends on how many suppliers actually send electronic invoices, and that is a change management programme, not a software setting.
  • Growth by acquisition, including Glantus, has left overlapping analytics capability and integration work still in progress, so buyers should check which components share a data model today.

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

Answered from the vendors’ own pages

Basware: Should we buy Basware if we only operate in one country?

Probably not. Its main advantage is multi-country e-invoicing compliance. In a single jurisdiction, cheaper AP automation gives you the same result.

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
Basware: Does it handle mandatory e-invoicing regimes?

Yes, and that is the core reason to choose it. It covers a wide set of national mandates as a service rather than an integration project you run yourself.

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
Basware: What drives the price?

Invoice volume, number of countries and modules. It is quoted, and implementation with ERP connectors and supplier onboarding is separate.

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
Basware: What determines the return?

The share of invoices arriving electronically. Touchless rates depend on supplier adoption, so budget for a supplier onboarding programme, not just the software.
