How does the free tier work exactly?

Every provider gets a free tier each month: your 10 highest-value invoices are processed free of charge. No setup fee, no monthly subscription fee. If you issue 10 or fewer paid invoices a month, Komashi is completely free to use — with no time limit.

If you have more than 10 paid invoices in a month, fees apply to the invoices below your 10 highest-value ones, based on your annual revenue tier.
