04Is Stax worth the money?
Stax is worth pricing out if you want payment processing, subscription billing and embedded payment options from one vendor. The pricing page lists subscription prices by annual processing volume, but the headline monthly fee is not the whole cost: transaction and ACH fees can add up, and equipment prices are not published. The higher-volume tier also moves to custom pricing. Compare your expected volume, payment mix and any equipment needs before treating the starting price as your budget.
