Account owners can change the payment method on their account by going to https://www.instrumentl.com/card. Alternatively, you can navigate to Account > Settings. Please note that you must be logged on to Instrumentl for this link to work.
You will then be prompted to update your billing information. Instrumentl accepts payment via credit/debit card or ACH bank transfer.
If you would like to switch to ACH bank transfer and are not seeing that option in your account, please shoot us an email at hello@instrumentl and we'll be glad to help!
