Where the line crosses
Break-even is the subscription divided by the rate. At 149 zł and 3% that is 4 967 zł of turnover a month: below it a percentage is cheaper, above it the subscription is, and the gap widens in a straight line. A 10% rate moves the crossing to 1 490 zł; 30% moves it to 497 zł. So a venue taking a dozen online orders a month should not switch to a subscription because subscriptions sound modern.
