If you receive a payment to your bank account that has a reference number that:
- matches the length of Lyyti's reference numbers
- has the number 7 in the positions 2, 3, 9 and 10
- the payment cannot be linked to any payment in Lyyti
...then you will see the payment under Finance --> Failed reference transfer payments. Generally, there shouldn't be any. However, if you receive such a payment, you can edit the payment and give it a new reference number that matches the correct invoice in Lyyti.
