Saved payment methods
PractitionersYour card is saved securely at your first checkout so reorders take one click. Card details are stored by our payment processor, never on Kaerwell's servers.
Adding a card
We accept Visa, Mastercard, and American Express. Add a card in My Account at any time, or enter it at checkout and tick "save this card"; it appears as a saved payment method on your next order.
Removing or replacing a card
Remove a saved card yourself in My Account. To replace it, add the new card in My Account or at checkout.
Declined cards
A decline comes from your bank, not from Kaerwell, and the message at checkout depends on the reason it gives. The usual causes are an expired card, a billing ZIP that does not match, or a daily limit. Try another card or call the number on the back of yours.
Paying by ACH or invoice
Pay by card or by bank account (ACH) at checkout. Invoicing is not offered.
