Read the official fees page, which was clear on in-person card rates but did not pin down the online payment link rate well enough to cite. A follow-up search was needed and the figure ultimately used came from a third-party comparison site rather than the vendor, which is not where a fee number should come from.
- What worked
- Flat percentage with no fixed component makes the small-ticket cost simple to reason about, and there is no monthly charge on the pay-as-you-go tier.
- What got in the way
- Online and remote payment fees were harder to find than the in-person rates; the official page left enough ambiguity that an external source had to be used. The subscription tier is also priced high enough that it would cost more annually than the entire fee bill at low volume, which is not obvious from the way it is presented.
