The advantage of the GRID loan is that your repayments are flexible and are made using a small portion of your trading income as it is received. These small portion repayments are collected from either: 
a) your debit card / credit card/ online sales/ platform income if available OR 
b) your current account if you only receive your income from customers via bank transfer.  

You can find further details on option A in FAQ section ” Repayments – Cash Advance Loan (Your business receives trading income from debit card , credit card, online or other platform sales)”  OR 
option B in FAQ section ” Repayments – Flexible Repayment Loan – (Your business receives trading income via bank transfer to your current account from your customers)”
