Invoice Koi, compared

Eleven invoicing apps, 59 features, read from each vendor's own pricing page on 7 September 2026. Six of the eleven have no free plan at all. Each page also lists what that app does better than this one, because a comparison without that list is an advertisement.

Free means free. 33 of the 59 features are in the free app, at 100 invoices a year and with no cap at all on estimates or clients.
A blank is not a yes. Where a vendor does not name a feature on the page where they ask for money, the row is scored as not stated rather than counted in our favour.
One price. Pro is $99.99 a year, billed once, with no seat maths and no plan above it.
