Credit Card interest

I am using a credit card for my inventory purchases, I set it up.
The problem is there is an interest of 0.03% daily till paid… how to set it this in MANAGER???

You have not been clear about how this is assessed. Do you know what the interest is when you pay? Do you receive any grace period following issuance of the statement? Do you only learn what interest has been assessed after your payment is processed?

Whatever the situation is, you must enter payment of interest as a line item on a payment transaction, posted to an expense account like Interest or Bank fees. Normally, you would record payment of a credit card balance as an inter account transfer in Manager. The interest must be separately entered, however, to record the liability. Of course, the credit card processor will be the Payee for the interest.
