The short version

  • Only Chargebee has a free tier, so it costs nothing to try first.
  • Each has a real cost: Chargebee priced as a percentage of billing, 0.80 percent on pay-as-you-go or 0.65 percent plus $99 a month on the committed plan, so the fee rises with revenue; 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
