SimpleFlow is available in the following two plans:

Free Plan

This plan is available for small teams or evaluation purposes at no cost.

If more than 3 users are present on a board, workflow actions (such as progressing or approving tasks) will be disabled on cards.
To continue using SimpleFlow, please reduce the number of users to 3 or fewer, or consider upgrading to the Pro Plan.

Pro Plan

This plan allows unlimited users.

Payment

Payments are processed through Lemon Squeezy.

Important Notes

If multiple administrators attempt to purchase from the Power-Up settings at the same time, duplicate charges may occur.

This is unlikely during normal use, but we strongly recommend that only one administrator performs the purchase.

Support

For any questions or issues related to payments, please contact Lemon Squeezy directly.
