Zip Business Trade Plus is a reusable account.
For any purchases you make during the month you will receive a statement with your closing balance at the start of the following month.
You have until the last day of your statement month to pay off each of those orders with no fees.
Here’s an example:
If you make your first purchase on the 1st of March for $1000, you will receive a statement on the 1st of April with the closing balance of $1000 (assuming you don't make any more purchases). This balance will need to pay off by the 30th of April for no fees.
If you do choose to split your payments into installments, you will have 4 equal payments of $257.50 starting from the 29th of April. The installment to be paid includes the 3% repayment fee.
