Which plan should I choose?

Plans trade a monthly fee against what comes off each sale. If you are just starting or selling occasionally, Zero costs nothing monthly and takes a larger share per sale. As your volume grows, a paid plan works out cheaper overall.

The turning point is Growth: from there up, Frontstore takes no share of your sales at all — you pay only the card-processing cost. So past a certain volume, every extra sale you make costs you nothing more in platform fees.

You can change plan at any time — there is no lock-in, and moving down to Zero is always available rather than closing your store.
