To accept payments you need to connect a payment processor, and for ManaKeep we integrate with Stripe.
You can connect a Stripe account from the Sell -> Settings tab of the Admin panel. When connecting you will be asked a few questions to create your account and can be accepting payments within minutes! With your Stripe account you can accept payments from major credit card brands including:
- American Express
ManaKeep does not charge any transaction fees on your sales, however Stripe will charge you a processing fee. You can view Stripe's fees here
