If the tattoo you want is more than the spending limit that you have with INKPAY, you can pay the difference yourself to the studio and then the rest goes on INKPAY.
You will still need to pay the initial 40% payment on the day when accepting your INKPAY job and then 3 x 20% repayments fortnightly, from the day of getting the tattoo.
Please be aware that any payment made to the studio, is directly between yourself and the Studio and is in no way part of your INKPAY repayment plan.
